Jacob Pruiett Final Project

For my final project, I created a board game: Radical Robots! The main idea behind the board game was to create a game that caused players to need to make a lot of decisions and estimations of the odds to succeed. For this game I needed a large board, a number of tokens, trackers, and finally the meat of the game which consisted of almost 200 cards, with around 60 unique ones. A large portion of my time was spent developing the cards, but in terms of the physical product, here are some in progress shots:

Here were the first prototype cards I made

And a play test being setup between me and a few friends

And here are the final iterations of the cards as they are being cut out

Printing out the board proved easier than I’d thought, and it came out perfectly on the first time

Here is the final project all together during presentations

I’d say the most difficult part of the process was, ironically, the parts I’d initially thought would be the easiest, which were the printing of the cards and cutting out the tokens. For the cards, I wanted to originally use a sturdier material than plain copy paper, so I initially tried to find card stock, but we didn’t have any white card stock. I tried to print on black card stock just out of curiosity, but that didn’t work. I also tried photo paper, but that only prints on one side, and thus doesn’t work for cards. Finally, I resigned to using copy paper, with some example mock ups with a piece of card stock sandwiched between two pieces of copy paper. Additionally I had some similar issues using the laser cutter with two sided acrylic, and ended up switching to wood in the interest of time. Overall I’m pretty proud of my work, especially with the design of the art on the board and the back of the cards, and also the fact that, despite the sheer volume of rules and complexity of the game, it’s pretty playable.

 

For this project, my two main learning goals were one: “to learn how to use the poster printer to make a game board, and also how to use/design smaller objects with the laser printer since I’ve only done larger pieces so far.” and two: “to learn about game design and playability from the perspective of a creator instead of a player.”

For my first learning goal, I learned both the goals with ease. The poster printer was far easier to use than I had anticipated, as it turns out it basically functions like a normal printer, just on a larger scale. The smaller objects in and of themselves turned out fine with the laser printer. What the actual issue turned out to be was the material I used, as mentioned previously. Most notably, the settings for the double sided acrylic on the universal cutter are incorrect for 1/8″ material, and it would have required a lot of tinkering to get it right. For printing, ironically enough I learned more about printing cards on normal printers than I did for the poster printer. Most notably I learned how utterly time consuming prepping card pages for printing is, since both back and front pages must be aligned, and to get the right card ratios for balancing, it required almost 50 unique pages to be printed out, some multiple times, others only once or twice. I learned a lot about working with Inkscape as well, since I had to make all of the borders and back art for the cards, and then also all of the design for the poster. One major effect I learned was color correction of external images by overlaying a box over the image and turning down the opacity, allowing me to change the color and visibility of the picture to my liking. As I said previously, I’m especially proud of how these designs came out.

For my second learning goal, I’d say I learned quite a bit, but not as much as I’d hoped. I was only able to play test the game once before presentations, so I wasn’t able to iterate as much as I would’ve liked from a design stand point. However, what I did learn was quite interesting. In my first draft, I was so focused on the complexity of the rules and how interesting the mechanics could be, that I didn’t think about how those mechanics impacted time. The first play test we did took just over two hours, so it was quickly decided that changes needed to be implemented to reduce the amount of time it took to play. In particular, the issue of how quickly players progressed from the start was important, since it seemed to take a while for the game to ramp up. In addition, adjusting the requirements for what you need to fight bosses was also important to change. However, I did receive positive feed back about the core mechanics, so I believe the main thing to do in the future is simply to continue play testing and iterating on that. Overall the process opened my eyes to how easy it is to become overly absorbed in certain aspects of a project, and helped me appreciate just how much work goes into producing a well balanced and fun board game. Despite not being perfect, I do think the game has a solid core, and I’m proud of what I’ve accomplished with it so far. I don’t know if I’ll be able to, but in the future I would like continue working on this game and refining it, maybe even turn it into a proper product if I become confident enough in it.

 

Looking back through my write-ups, I’d say the most significant thing I’ve learned is how to fail. In most classes failure is cut and dry, and as soon as you fail that’s it, you have no chance to try again. In this class it’s been actively encouraged to fail, and then try again so that you can learn from your mistakes. In most courses failure simply results in a feeling of dread and anxiety for your grades. Here it spurs you to improve because you actually have the chance to improve, and I think this has greatly improved how much I’ve learned from this course because of it. Most importantly what this means is that I feel I can more confidently fail and move on from said failure in the future, which will be a very important skill not just in work, but in life too. 

 

This class has definitely spurred me to think about myself differently. Because of this class, I’ve relearned how to enjoy making. Prior to this class, most experience I’ve had with making were in my major, in sterile, grade driven experiences. All my previous experiences in making have been dull and life sucking, but over the course of these assignments I’ve learned that I still have the spark and drive for creativity. It’s been quite a liberating experience for me. On some projects I was not able to do as much as I’d wished, or didn’t fully implement what I’d want, but it wasn’t failure on a points or grade based level, it was failure on a personal level because I was invested in the projects themselves for their own sake, not for the sake of some grade that is supposed to somehow tell an employer my capabilities. 

I look forward to continuing to work as a maker in the future, whether in my work, or simply as a hobby. To be a maker is simple, after all: use your creativity to produce something. Previously I had thought of it in a more bland way, thinking making was just creating a product, but now I think the spark of creativity and the drive of passion are essential to being a maker as well. And I think I’ve gained these thanks over the course of the semester, in no small part thanks to this class.

I feel more confident in myself as a creative thinker, and more passionately about my work as a maker, and for that reason I’m incredibly glad I’ve taken this course.

Final Project – Grant Johnson

Q1:

For my final project I decided to construct a Bluetooth speaker. Some challenges I faced during this project include: Part shopping for the proper parts that would all work together and create a decent sound. Learning how to solder and using it to help add security to the internal wiring of the speaker. Figuring out how to power the speakers in an efficient/mobile way. Figuring out a well-designed layout for the housing/case that fits properly to help hold everything together. I’m proud of a couple different parts of my final work. I really like the aesthetic and physical design that I landed on for the final version and think that given a second go at it I could create an extremely cool looking exterior to the speaker. I also was just proud that I was able to get everything to work. I’ve never had a lot of experience with working electronics besides computers and it was cool to get a chance to mess with something set up so very differently.

 

Q2:

My learning goal for this project was perseverance – I wanted to try and take this project beyond the point of simply ‘being functional’ and make it visually interesting and finished looking. I think one thing I definitely took away in the making of my speaker was that perseverance takes a ton, ton, ton of time. Trying things out, looking at stuff in different ways, and really finalizing what you want your creation to be takes thinking and experimentation until you can’t take it anymore. I still think that I have yet to hit my peak level of perseverance – I didn’t quite end up with the final product I wanted by the time the showcase rolled around (I would have liked to have had reactive LEDs and button controls. I didn’t necessarily not meet these goals because I lack the skills to be able to take on the challenges I set for myself, it was more because I didn’t actually force myself to take the time and really try everything as much as I could. I think one thing that I could definitely benefit from more is documenting what my construction process will look like before-hand so that I can get a better idea of problems that may crop up in the process. I’ve also come to realize how much this helps you figure out what you can do at different substages and helps identify different problems you can tackle within projects while waiting on other things to get solved or become available. All that said, I’m still insanely happy with my final product. As stated earlier, I’ve never really messed with electronics much besides computers and it was fun to make something that’s more on the ‘analog’ electronic side of things because I think the simplicity of how stuff like that works is very interesting. I was also really happy with my ability to solidify this product in a very short time. I was in a huge time crunch at the end of the semester and the fact I was able to create a finished product within a week or two is crazy to me. My project is also meaningful to me for two different reasons – one, it’s my first ever Bluetooth speaker (I’ve never had one before) and I got to make it myself and decide how everything would work and what functions suit me. Two, this project (as well as the iteration project) has shown me how I can take all the stuff I’ve learned in this class, as well as others, and apply them to solving problems myself as opposed to hoping that a solution is created by someone else. This autonomy is really powerful in my eyes and something that I definitely want to foster in myself.

 

Q3:

I think there are probably two main things that I’ve built in myself over the course of the semester. The first, I would say, is the ability to get over my usual fears of talking to others and trying to have them give advice and/or help when I am trying to figure out an idea/project. The sense of community that gets fostered within a fab lab really is palpable and you realize very quickly how helpful it is to be surrounded by a community of people with similar goals/objectives as you, with skill levels across the spectrum in a broad range of topics. It’s also great to use other people as a way to figure out if what you’re trying to communicate or design is coming across in a way that makes sense or works. The second thing I think that I really gained over the semester is the ability to be unafraid to tackle a variety of different skills/crafts when approaching them from an exploratory place. There’s definitely a huge range of topics we cover in this course and I think that doing that allows people to look to even more varied skills and feel as though they have the ability to at least try something out because they know how to use the resources, tools, and documentation that can point them in the right direction. I think that the openness to at least try to learn different skills (and combine them over time) is something really beneficial that can be taken away from this class. I also think that I have built my confidence in my ability to fabricate and create things significantly. I’m an art minor so I’ve had opportunities to make tons of imaginative stuff, but never to design so thoughtfully and never to create more tangible, interactive objects. This confidence definitely makes me want to come back to making things more often in the future and taking on projects similar to those we did throughout this class.

 

Q4:

I think this course has definitely helped me feel more connected to my STEM side in some ways, which I really appreciated a lot. I first came to UIUC for CS and then switched after realizing I wasn’t nearly as prepared as a lot of people coming in. This class felt like it bridged the gap between that style of thinking and the styles of thinking I see in classes like my advertising classes or my art & design classes. Even before I took this course, I would probably describe myself as a maker – I enjoy creating my own things and realizing my own distinctions and personal needs and design principles. I think it has become harder and harder for people to describe themselves as makers as time has gone on, but that nearly everyone can take on the role should they choose to. Making is something that is totally within the grasp of anyone, you just need a lot of persistence, patience, and passion. I think this class (and this semester for me personally, as well) has spurred a lot of those three things in me. I’ve started to realize that you can easily fall into some role where none of those things are really an importance, but I personally enjoy the personal growth that can come out of trying to achieve these things. I do still agree with Papert that the most significant learning is hands-on and personally meaningful. I think this class has really shown that to me. I’ve created a ton of stuff in a very short time that’s honestly super cool and decently practical. I’ve seen this through other classes as well – the one’s where I’m making stuff that is going to benefit me and personify me definitely catch my attention the most and help me hold onto the things I’ve learned the best. I think that having the chance to just get your hands onto different things can really help you figure out how you feel about different topics and hobbies in a much quicker way than just reading about it or hearing about it. Answering tests is great and all, but actually being able to show the knowledge physically is really great as well. I also think that working with your hands also just allows more nuance to the learning process and gives you a bigger connection to what you’re working on.

Final Project: Sonar

Final Project

For the final project, I decided to use an arduino and the HC-SR04 ultrasonic sensor. Although the sensor was quite basic, I have not used it before, so I decided to use it for the final project. Another reason I used the ultrasonic sensor is because I wanted to create a sonar system with the arduino, as the sonar does use ultrasonic sounds and sensors. I also decided to create the very familiar sonar visuals we see in movies and tv shows. As I am not really well versed in making visualizations, I thought this would be a nice challenge for me.

 

Process and Finished Product

 

 

The first compromise that I knew that I had to make was to make the sonar a semicircle instead of a full circle, due to the limitation of the servo motor. I also initially tried using d3.js, a visualization engine for javascript. I chose this as it was my TA Dot’s suggestion, and also because I thought that I could use the d3.js skills that I would gain from this project, and apply it to a different project that I was working on at the time. Unfortunately, connecting the arduino to d3.js proved to be very challenging, and after a bit of searching on the internet, I decided to use Processing instead, as getting data from the arduino was more straightforward.

 

My first learning goal was to learn how to use the HC-SR04 ultrasonic sensor. Although it is included in the basic arduino kit in class, I have never thought of using it, and had never felt the need to use it. Using the sensor proved to be fairly straightforward, but synchronising the ultrasonic sensor to the servo movement was a bit challenging. Due to the nature of how the HC-SR04 sensor worked, the time it took to take a measurement varied based on how far the object was from the sensor. Eventually, I discovered a library called NewPing, which allowed me set the maximum distance to scan for, and maintain the same scanning time for each scan.

 

My second learning goal was to challenge myself to create visualizations for data. I have never been a very artistic person, and creating any kind of visuals, whether it be drawings, or UI design, was very difficult for me. However, as I had something to base my design on, I thought that creating the sonar visualization would not be too bad. Furthermore, when creating the visualization, I worked up from tools that I was familiar with. Once I had a rough design and sketch based on what I could find on the internet, I first started with creating a svg file for the acrylic print. As I did not have to worry about colors, I could just focus on the layout of the visualization, and I think it really helped me to get a solid layout that I could utilize in the graphical visualization. Then I moved onto creating the actual screen visualization. My initial attempts with d3.js did not work out, as getting the data proved to be a problem. So, I quickly switched over to Processing. Although I did not know any Processing, I was able to get a basic grasp fairly quickly, and create the visuals. As I already had a layout for the visualization, all I had to do was copy over the design, make color changes, then add dynamic visualization elements, that would interact with the data from the Arduino.

 

As a whole, I am quite satisfied with the project. I was able to achieve my main goals, which were to learn how to use the HC-SR04 ultrasonic sensor, and to create a sonar visualization that would show what the sensor was reading. I was also able to create a physical representation of the sonar visualization, so that any object that was placed on the physical representation could show up in the Processing visualization. Although my final project does not really have a practical use, I am really happy about the way it turned out, especially the visualization.

 

Looking back at this class, I realize that I’ve become to embrace failure and learn from it. I’ve been the model student in most of my classes all the way up to highschool, and even at the University of Illinois, I have never really struggled with academia. That being the case, failure wasn’t really something that I experienced often, or even at all. Throughout this class, however, I was exposed to numerous failures, which was not something that I was used to. For example, during the 3D printing section, I had to reprint, and improve my 3D model, either because the print did not work out well, or because the print did not fit the raspberry pi that I had. Even in the end, I had to file the finished casing, so that it would fit my raspberry pi. Another example is the locomoting pom pom bots. In this assignment, I had to do a complete redesign of the bot, as what I thought would work, ended up not working at all. Even with the new design, I still had to make improvements so that it would actually work.

 

One thing that I was surprised about was how much I enjoyed sewing. I have never used a sewing machine until this class, and honestly, I was not too excited for sewing. However, I ended up really enjoying sewing, and the assignment on sewing took the most time out of all assignments, simply because I enjoyed it. Sadly, the finished project wasn’t perfect, but I was still proud of myself for being able to learn a completely new skill, and being able to apply it in a functional product.

 

This class showed me that with the right tools, and within a reasonable range, I could make anything I wanted. I also learned a lot of tools and software skills to aid me, and that I could usually find them at makerspaces. Furthermore, I learned that when I don’t know how to use a certain tool, people at the makerspaces were very willing to help out. I also think the hands-on learning fits the class very well, as we all had to use what we learned in the class, to make our projects.

 

I had no idea what a maker was, but this class gave me a good definition on what being a maker is like. I don’t think I’d be able to give a concise definition of the word “maker”, but throughout this class, I have experienced to a full extent, what being a maker is all about. Being a maker is doing a lot of hands-on work, creating prototypes and projects that I can think of. Although something might not work out, makers try and try again until it turns out better. Even when you achieve what you set out to be, you then soon think of ways to improve your project. Most importantly, you get to have fun while doing it.

Final Project

For my final project I wanted to reproduce something similar to this art piece made by Ben Young using computerized machinery:

“Stead” by Ben Young

The original piece was made using cast bronze for the “positive” half and hand cut layers of glass for the “negative”. In order to reproduce this in the FabLab I decided to use the CNC machine for the positive half and layers of laser-engraved acrylic for the negative. I started off by using the laser to cut and engrave the sections of my negative half before gluing them together

Sections of the negative half fresh from the laser

Layers stacked (pre-gluing)

Layers glued

For the CNC milling I used the Manufacture tab builtin to Fusion360 to generate two passes on the model. From there I sent the tool path to the CNC machine and periodically removed sawdust that accumulated.

Result of CNC milling

CNC Toolpath

Once I completed both the negative and the positive halves of the sculpture all I had to do was glue them together and let them cure. You can see results of the final steps below.

Final Sculpture from Above

Final Sculpture from the Front

The hardest part of this process was the gluing together of the acrylic cutouts. The edges of each piece needed to be filed down with sandpaper on both sides in order to make a channel for the glue to enter and increase surface area. Then each cutout needed to cleaned with lens cleaner in order to reduce the amount of particulate stuck in the final model. Each adjacent cutout was then clamped, glued together and allowed to set for three minutes

Through out my making career in this class and prior to it I have noticed that as soon as I finish a project I always have several ideas about how to improve whatever I just made and make it better or more polished. Because of this, I decided to making one of my learning goals to make smaller prototype versions of both components of the sculpture so that I could learn from them and hopefully produce a higher quality final product.

Front View of Prototype

From this first prototype I learned several things that I implemented in the second revision. One of the things I noticed from my first prototype was that the effect was only visible for about half the depth of the model because the middle of the sphere was thicker than everything behind it. In order to address this I decided to use a cone so that the effect would be visible for the entire depth of the model from the front. Other changes included: wider surface area of each level, thinner sheets of acrylic, a new type of glue, additional tool-paths for the CNC, and a revised gluing strategy. Comparing my first prototype and my second iteration side by side I definitely think I achieved my goal of learning through prototyping.

Since this project was more artistic than my previous ones I also wanted to make one of my learning goals to get feedback from friends in order to involve them in the making progress. The majority of people’s comments were in response to the fit and finish of my first prototype. While this feedback was helpful in the sense that it lead me to make revisions before my second prototype it was not exactly the kind of feedback I was looking for. I was hoping they would suggest ways I could improve the artistic component of the project rather than the process of making the project itself. Perhaps their responses would have been different if I had asked more specific questions like “what emotions does this piece bring to mind?”.

After completing all of the projects this year I have noticed that I learn best when I am free to explore topics or area of topics that are most interesting to me. The freedom within each assignment really helped me engage with the tools being used and learn meaningful skills. The simpler and smaller learning projects that we completed in lab sections were very helpful in learning the fundamentals of each tool area, but the projects we completed on our own each week let me explore the component of each tool that most interested me. For example the name tag assignment let me explore use with acrylic even though what we did in lab section was with wood, and the copper tape assignment let me incorporate electronics into origami which was quite different from what we did in lab.

At the beginning of the semester I considered myself a maker. I had worked with 3D printers quite a bit and had other experience modifying electronics in Nerf guns. Looking back though I don’t think I would consider myself a maker back then. To me being a maker is heavily reliant on engaging with some sort of community. Whether it be a physical maker-lab or an online forum, the ability to share what you are doing, help others, and get help for yourself is really at the core of the maker movement. Additionally, I think that cross discipline thinking as well as the incorporation of multiple mediums or tools is another tenet of the maker movement. Throughout this semester I have learned to use a variety of new tools and have worked with other people in the fablab to create some really interesting projects. Although I considered myself a maker at the beginning of the semester I think now more than ever that is true because of my experiences with this class.

Final Project Reflection – Nicholas Agate

     My idea for the final project was an electric guitar pedal board. I did not previously own a pedal board, and because I play guitar, it is something that I was enthusiastic about making. In all, the project involved utilizing Inkscape, Fusion 360, Tinkercad, Meshmixer, the Universal Laser Cutter, a resin printer (my new tool area), wood conditioner and stain,  plastic primer and pewter spray paint, and a hammer and finishing nails. Please see a few in-progress images below.

     In the beginning, I had a rough idea of what I wanted the board to look like, and I am happy that the final product came out as I had envisioned it. I was planning on making a pedal board that would have dark wood and decorative metal-looking pieces on the side, and the end product definitely fits. I am also proud of the fact that I completely designed all of the pieces for the pedal board myself. I did not use any files from online, and it felt good to design the whole project from start to finish. However, even though I am very happy with my pedal board,  I did run into a couple of issues along the way. The first was that my PDF files of the pedal board were not being read correctly by the Universal Laser. I ended up fixing this by opening up my Inkscape SVGs on the laser’s computer and making sure that the width and color of my lines were correct before saving the files as PDFs. The second problem was due to the strength of the wood glue that I was using. The cross panels that serve as the platforms for the guitar pedals are able to hold up to the stress of pushing the pedals down, however the wood glue that held the panels in place gave out. My fix to this problem was nailing the panels into the sides of the pedal board with finishing nails. Please see the final pedal board below.

     The first learning goal that I had for this project was to incorporate suggestions from those around me, because I think that it is easy to work to your own beat and miss out on valuable input from others. The two parts to this pedal board that came from outside suggestions are the individual cross panels and the metal-looking pieces on the sides of the board. I originally planned to make the board’s top one solid piece of wood, but my roommate, Matt Goodalis, suggested that I use individual strips of wood so that any wiring could be kept out of the way. The second piece of advice came from Duncan Baird, my instructor. He introduced me to the idea of using the resin printers to make objects that I could paint to look like metal. I am grateful for both of these suggestions because they made it into my final product and led it be functional and aesthetically pleasing. By the end of the project, I also learned to further reflect on the design decisions that I make. The input from my roommate especially showed me that some designs can be improved upon if you just spend more time thinking about their practicality.

     My next learning objective was to use a new program that would help me during the design phase of this project. For this I used Autodesk Fusion 360. I found that being able to turn SVG files into 3d objects was very helpful. I was able to take my designs and extrude them, so that I could better understand how the pieces would fit together and look once I had them all cut out. But outside of these benefits that the program afforded, I was also able to develop my planning skills. I have mentioned before that my planning felt week in earlier assignments, so this program allowed me to slow down and consider the shape and measurements of my pieces further. I am glad that I created this goal for myself, because the success of this project has shown me the upsides to extensive planning before making, which I can utilize in the future. Please see an image of two of my pieces in Fusion 360 below.

     Finally, the learning objective of using new materials was satisfied through the use of resin. It was interesting to see how resin was formed in the printers, and the decorative pieces that I created definitely add an interesting dimension to the project. However, if I were to redo this project, I would use a different type of wood. I knew that I wanted to do laser cuts in order to get precise pieces, so I went to CU Woodshop Supply and Home Depot to see if there was any interesting wood that I could use. Unfortunately I could not find any quarter inch pieces that would fit into the Universal Laser, which caused me to go with the plywood staining route. As I said, I am happy with the project’s outcome, but this is something that I would like to have done differently.

     Next, after reviewing my previous posts, I have realized that I tend to push myself more with a tool area once I am familiar with it. I do not necessarily think that this is a bad thing, but I could learn even more by challenging myself earlier on. That being said, I have become a lot more comfortable with making. I am majoring in political science and I am attending law school next fall, and up until this point, I have had very little experience with making because it falls outside of my studies and hobbies. Using machines like the laser cutters and the 3D printers forced me to step out of my comfort zone, and I am glad that I did. I have found that I really enjoy making, and I would like to continue doing it in the future.

     The making area that I enjoyed most in the lab was laser cutting. Besides taking a middle school woodshop class, I have not had a lot of experience with wood working, and I have grown to enjoy it. Most of the staff has a specialty area and if I were to pick one, this would be it. It was exciting to plan out projects and see them take shape while using the laser cutters. And afterwards, I brought the project into my original vision by staining and putting on the final touches. Because of this project, and the class as a whole, I feel comfortable calling myself a maker. It is not something that I would have attributed to myself in the beginning of the semester, but I have learned many new skills in multiple areas, and this final project has especially made me realize that I have the ability to create unique and useful projects. To this end, I hope to continue being a maker by engaging in more woodworking for future projects.

     Lastly, I would again like to thank Duncan Baird and Matt Goodalis, who helped by contributing invaluable ideas to this project. I am also generally happy that I learned a lot in this class while getting the chance to make new friends. Hopefully I am able to stop by the Fablab during future visits to the University of Illinois.

Brandon Steinman – rPi Spotify remote

My project was a remote for Spotify that uses a Raspberry Pi! Here’s a video and some pictures:

https://drive.google.com/open?id=1MnYq4t5ndoUcT1hqxvZUtVsYOOhNk6Vr

https://drive.google.com/open?id=1KTpwBM7kF4PzIG4ypB2lqN8Es04UZvi8

https://drive.google.com/open?id=1cV3f6Mue8If9o6HH6b5eFgylF3EdY0Tl

  1. The most difficult parts of this project were getting my app to properly authenticate with Spotify’s API (their process is a little weird) and also creating a full program that combined objects from different libraries (this was my first time doing it in python). I’m most proud of getting through that last challenge, it took a lot of trial and error, and I gained a lot in terms of skill that I’d wanted to have claim to for a long time.
  2. My main learning goal was to iterate on my project once I became satisfied with it. I did embrace this mentality and made a sustained attempt to iterate on it once I had a working product. I tried to improve my Raspberry Pi project by automating the script triggers. I wanted to do this so that my project presentation would go more smoothly. I tried two routes: the first was to trigger the script to start when the Raspberry Pi boots. This caused dependency issues with the library ‘spotipy,’ and I really did not want to try to fix that and end up in over my head with a mass of hotfixes that could endanger the program and even the OS as a whole. I then tried to time the script triggers with crontab. I sank all my remaining time into this, and eventually had to give up, as the crontab logs were very unhelpful as to why the program wasn’t running. So, in a way, I ended up meeting my goal, but didn’t really have anything working to show for it. I’ll continue trying to get it to work, and to iterate on it in different ways. I’ll probably try to fill out the design and execution of the remote idea with my electronics at home. This is because this project was something I really care about and it would serve me well (and maybe others) to come up with a well-polished, finished product to show for this.
  3. I think one thing that is key to my learning is that I need ample time to make mistakes and learn over and on top of them. If I don’t end up giving myself enough resources to make mistakes, things often spiral into a mess of doubt and anxiety and sometimes things turn out right, but either way, cramming stuff in both in terms of time and by way of learning the tool on the object that I’ll be turning in as the end result. Neither of those work well for me. This feeds into how important repetition is for me, since some of my best work is in projects where I made lots of mistakes and iterated lots (sewing project, final project, stickers, etc). I also realized that I’m a lot more active and involved in a project when I believe that I’m going to end up using that experience sometime later. This makes me a bit sad, as it kind of seals my fate as a pragmatist. For example, I was instantly super involved in the sewing project because I knew it was a super useful skill and something I’d want to get artsy with later. But with the pom-pom bots, it’s pretty obvious that I didn’t get super involved as a result of not believing in it as a ‘useful’ experience. Granted, oftentimes I’m good at convincing myself either way of that, but for that project, I was probably just out of steam.
  4. I certainly feel like I’ve developed my confidence, as a maker, quite a bit. It was naturally difficult to get more relaxed while working in the makerspace, but the people there and this class gave me every opportunity to do so! It was a great experience and I look forward to spending more time on all manner of projects in the makerlab! This course has convinced me that I’ll have a happy longevity in making, due to the opportunities in community, learning, and tools resources that makerspaces offer. At this point in the year, my understanding of what all those things mean has also developed quite a lot. I’ve learned about the culture and societal dynamics surrounding makerspaces at large. Tangentially, it’s convinced me that I should go back to volunteering with the Urbana Bike Project. To call myself a maker is to recognize my incapability of doing nothing most of the time and having to act on my creative ideas. In comparison with my thoughts on the Seymour Papert quote at the beginning of the year to now, I’m in essentially the same standing. I have a good bit more experience on the personally meaningful aspect of it, that at times, that part is just as essential to the hands-on aspect. The hands-on aspect made this class much more significant, to the extent that the class wouldn’t work without being as hands-on as it is. The knowledge and experience gained is vital. To this day, I haven’t forgotten how to use a 3D printer, soldering/electronics tools, CNC lathe, Drill press, band-saw, dremel, arduino, shop-bot, and Autodesk Inventor, all because they were extremely hands-on and involved processes (all of which I learned at least 2 years ago, experiences that I am very lucky to have had). I expect the skills that I learned in this class to stick with me for the same reasons. I’m probably primarily a kinesthetic learner, so thank you for designing this class with people like me in mind!

Issues Encountered and The Pride Found

I chose to use many new modules, such as the ESP32 and the MCU-6050, which were decidedly more complex than what my project required. I also ended up using new tools, such as soldering and using Bluetooth, which complicated things further. Compiling code onto the ESP32 module only worked half the time, and learning to use Bluetooth ended up being much more complicated than I thought, since it had to comply to Bluetooth standards. This project also necessitated that the entire device would fit within a glove, and to do that would require soldering the modules onto a perforated board as opposed to attaching everything via breadboard, something I had zero experience with.

Ultimately, I am proud of finding the solutions to all my problems. Despite the project taking more time and the problems encountered were more complex than expected, I am proud of taking the time to dedicate making the project a functional reality.

Learning Goals

The first learning goal was to learn about hardware and E-Textiles, as well as learn more about wireless devices and how they work. My second was to evaluate my product of two weeks to the original 1979 Nintendo Power Glove, which had a team work on it over the span of eight weeks. I wanted to see how the advancement of technology could change what is possible and by whom.

For the first goal, I definitely felt I learned a lot about a field I did not know, particularly hardware. I learned about prototyping with perf boards, the benefits of that instead of going straight to a PCB, as well as circuit design and how to solder. This is also the first time I needed to work with fabric, and so I had to figure out a way to keep the flex sensors snug to the finger of the glove while still needing it to be easily removable. Ultimately, I feel like I gained a valuable and diverse skill set through this project, and thus I feel like I accomplished my first learning goal.

For the second goal, my end product was successfully able to play Pokemon Yellow and Tetris on the Game Boy. While possible, no participants were able to successfully complete World 1-1 in Super Mario Bros. This is on par with the original Nintendo Power Glove; the motions that players needed to use to play a game like Mario were too precise for the Power Glove to cater to. The same was true in my prototype. While I had to change how to take certain actions due to hardware limitations (such as replacing relative position tracking with a gyroscope), the problems that plagued the original Power Glove are also found in my prototype, which was constructed at a fraction of the cost over a shorter amount of time. Therefore, I believe my product is a fair representation of the Power Glove, and that the advancement of technology, while helping to reduce the costs, did not make the product any better or more intuitive than it did in the late 70s.

What I Learned From INFO490 – Makerspace

One of the biggest things I have learned about myself is my level of dedication I can to seeing something to the end, regardless of the medium it’s being done in. There have been several points in this class where I am working on a project and I forget that I’m technically doing this for a grade; in my eyes, it’s all about completing it for the sake of the product itself, and not for the sake of getting a good grade. I believe much of this inspiration came from the staff at the Fab Lab itself; seeing people just passion for making and creating struck a drive in me to do better and make better.  

 

Introspection

I believe this course definitely had an impact in what I do in the future. I don’t want to be limited by my capacity; this class has shown me the resources readily available to me, and the amount of potential one can draw from fab labs if they simply take the time to draw it. I do not want to stop making or designing or creating simply due to a lack of resources or knowledge. In my opinion, whether or not I am confident to call myself a maker is as important as the grade I get from making these projects. In my head, anyone can be a maker, if they simply try to create; the title has no qualifications on the product itself. I found deep enjoyment and satisfaction from making this semester, and am confidence I will continue to pursue this interest in the future.

Final Project: Smart Trash Picker

Where’s The Report? (It’s In an Attached PDF)

My final project was on a “Smart Trash Picker,” and I have a short slide-deck explaining what that is, and you can view it here

Fully built Smart Trash Picker

 

I wrote up my final report within a Google Doc, and aligning the images in that Google Doc was difficult.  If I copy-pasted that material into WordPress, the formatting would all go wrong.  So instead (with instructor permission) I’ve included my final report as a PDF.  You can view that report here: Final Project Written Reflection

Textiles – Grant Johnson

During these weeks in lab we worked with textiles, sewing, and embroidery. I happened to also be in a fashion class this semester, so I was excited to get the opportunity to learn some new things that could add to my clothing construction repertoire. I’ve also never been around embroidery machines before, so that was an exciting prospect.

During the first week of this lab we had to make small drawstring bags. Since I missed the actual lab section, I ended up constructing this on my own at a separate time. I was definitely still getting a hang of dealing with the ‘right’ and ‘wrong’ sides of fabric during this time and as you can see in the pictures, some of the parts of my bag ended up in the wrong spot. I decided to make the most of this and have a bag that has outer pockets instead of the lining that it was supposed to have. I decided to hand sew some parts of the bag for practice as well (although now that I know a little more I always try and avoid hand sewing). Making this bag actually ended up kind of helping me in my fashion class as well, later down the line. When making two whole(!) outfits  for my final project I needed some way to secure the waist of some shorts I planned on creating. I thought back to this assignment and realized I could make a similar drawstring (coming out of the sides of the shorts) that would both be functional, as well as stylistically unique.

The following week in lab, we learned to use the embroidery machines to sew vector images into fabric. This is something I’ve wanted to learn about and play with for a really long time since I draw and have created vector images in the past that I think would be really interesting to sew into clothes. In lab I got the opportunity to make myself the majority of a squirrel patch (side note: embroidery can be really time consuming). I was really impressed by how accurate and clean everything looked with my squirrel. I realized there were probably a ton of really cool things I could do for my final embroidery. I didn’t really experience any serious issues with this patch in lab, but when it came to making my final piece I ran into a totally different set of problems in making a patch work out, which I will discuss a little later.

Build Process

For my final textile product I decided I wanted something that could be useful to me and serve a function instead of something that just looked cool (especially since I was still working on upping my fabric craftsmanship). When I looked through all of my options I eventually came across a pencil bag that I thought would be super helpful because I’m always searching for all of my different art pens, pencils, and other tools which can be spread across my apartment, throughout my backpack, etc. With this bag I would be able to keep everything contained and in one place.

I immediately thought of a drawing I had done a while back that would make the perfect embroidery to put on it and I thought about all the extra clothes I had at my apartment that could possibly used for fabric. I ended up deciding on a tie-dye shirt as the fabric I would use for the outer lining. Once I started working on the actual bag, however, I realized all the mistakes I had unwittingly made. My original drawing, vectorized, turned out to be too much for the embroidery machines to handle. The file size was too large, even when trying to reduce the density of stitches, turn outlines into running stitches, or trying to simplify the vector image. This was a major bummer for me as I really wanted to see that image in fabric form. After I gave up and decided to create a new vector image I began starting into my patch for the outside lining. This is when I ran into even more problems!

I soon found that the embroidery machines don’t quite work with t-shirt material by itself, not matter how taut you get it on the hoop. The fabric I had cut from my t-shirt ended up getting sucked down into the bobbin pit and getting all caught up in everything. I decided to suck it up, cut a new piece (the last I could get out of the t-shirt), and try it again with some stabilizer. The stabilizer did help some, but with my specific design having the heavy filled areas, it still ripped and ended up letting the fabric get caught up in the machine again. I tried one more time to no avail and just decided to get my patch made so I could move on.

I grabbed a piece of canvas and started into it. One of the types of fabric I tried to use to embroidery immediately broke and I couldn’t get it to work no matter what I tried (it was pearlescent and I think it just wasn’t strong enough for the tension the embroidery machine needs). What happened then is still somewhat of a mystery to me. When I started into my canvas piece it was late into the night and I was unable to finish before the fab lab closed up. I left my machine until the next day and started back into the patch. Somewhere along the way it got unaligned which ended up being the final patch you see on my bag. I decided that I was fine with just using that patch to try and get this whole ordeal over with. As per usual, I decided to try and work with what I was given and decided to try and use the patch as a little pouch on the front of the bag, to help give it some utility. After attaching that to the outer lining I ironed some interfacing onto the outer lining to help give it some rigidity. I then attached my inner lining and a zipper to enclose the whole thing. My bag ended up being a little different than what the guide was looking for, but I like the way it looks personally and think it is much more unique than the standard pencil bag.

Final Reflection

I had a lot of trials and tribulations in the process of making these objects, but I think that’s a lot of what getting good with textiles takes — experimenting and trying things out until the process makes sense in your head. I definitely think I need to spend some more time around embroidery machines to try and really get my skills up to par there and test out how you can make different fabrics work out with them. I also think that designing projects to be cut into pieces and aligned later takes a certain level of organization skill and planning that I still might not be at yet. Either way, I was still really happy with the items I produced and plan on getting as much use out of them as possible. That’s one thing I really love about textiles — the opportunities are so limitless and it’s instantly gratifying to make an object that can serve some kind of real purpose for people.

I learned a lot about handling machines through these weeks and in conjunction with my fashion class, this time period was a time where I really upped my skills in textiles a visible (at least in my opinion) amount. Being able to figure out ways to turn mistakes into benefits was definitely a skill I pulled out of textile work quickly. I actually bought my own sewing machine recently due to how much fun I have had with all the textile prospect I’ve taken on now and hope to make lots more stuff soon! Since I’m a little late in turning in this write-up, I’ve decided to include some other projects I took on in my fashion class in hopes for a little credit or at the very least to show that I do kind of know my way around textiles. There are more, but here are the highlights:

Final Project

Question 1:

For the final project, I created a press-fit constellations box powered by wireless inductive coils.

Initially, I intended for the box to be powered by a solar panel circuit. But along the way I ran into some revelations and restrictions that led me to replace the intended solar panel circuit for a wireless inductive coil circuit.

I used an online press-fit box generator to get the 5×5 box I envisioned and I imported an image of the sky into Inkscape to begin working on my design. I attempted to change the image to a vector image by tracing the bitmap but the vector image was choppy. Therefore, I opted to manually create each element of the image one at a time, from the stars to the lines of the constellations. I created the stars in the sky using the circle tool and the star tool in Inkscape. I used the pen tool to create the lines of the constellations. My main goal was to make sure the majority of the constellations would allow for light to pass through so that the constellations could be seen in the dark. For the lines of the constellations, I converted the stroke to a path, and removed the fill to give it a 0.001 inch outline, therefore creating a thicker line to be vectored.

This process took an insane amount of time because I wanted to really get the design right. I felt pretty comfortable on Inkscape, but there was still a lot of features in the program that were unknown to me so I was learning as I was designing. There was a lot of back in forth in designing.

IMG_2377

Overall, I was really happy with how the box and design turned out.

IMG_2391

Question 2:

My learning goals were to (1) challenge myself by learning and integrating wireless inductive coils into my design and the all the components needed to create the circuit because I was never really knowledgeable or comfortable with circuits before, and (2) to extensively plan out each of my steps before I started the project because I’ve found that I usually just throw myself into the assignments without thinking through all the factors and outcome.

For the first goal, I hoped to create a successful circuit that could power my constellation box. I was pretty much clueless on wireless inductive coils so I did a bit of research to find sources so that I could get a better grasp of all the components and functions. I read a few Instructables, blogs, and watched a few videos. I essentially followed the circuit diagram off of https://learn.adafruit.com/wireless-inductive-power-night-light?view=all and the circuit was successful. Before, I was a bit intimidated by circuits, but now I feel a lot more comfortable working with them.

As for the second goal, I really tried to hold myself to the goal. I created a step-by-step list for myself so that I could try to plan out all the components I would need beforehand. I found it helpful in the beginning but realized as I really started getting to work on the project, a lot of factors were shifting and at a certain point my step-by-step list kind of fell apart. But I still believe writing out the steps of a project is really helpful. It got me to really think about the logistics and design of the box in respect to the circuit as a cohesive piece, rather than the two as separate projects that needed to somehow come together in the end.

Question 3:

I’ve learned a lot in this project and the course. Often times, I got really frustrated when something would go wrong in an assignment. I would end up spending more time than I anticipated in order to fix the issue or coming up with an alternative. I treated arising issues as a barrier rather than an inevitable part of the process. I’ve always considered myself a good problem-solver, but I was never very comfortable when I ran into one. I think now, I have a much better approach to problems. I’m less emotional about them and more productive. I tackle the issues head-on.

Question(s) 4:

As an advertising major, I always saw myself as a strategist. To be fair, I’m not sure where I’ll end up but I’ve always been drawn to the duality of the profession. Analytic and Creative. This course allowed for me to experience with different mediums (almost all that were new to me) and I think it sparked the creative side of myself. I would consider myself a maker. To me, a maker is anyone who devotes their time and their craft to create something. Making is collaborative, challenging, rewarding and unlimited.

Final Project – Programmable Keypad – Mohammed Faiz Patangia

For my Final Project, I worked on making a programmable keypad. I idea behind this keypad is that it could be used for multiple purposes, like data entry, coding, gaming, etc. To build it, I needed several tools and materials, like Adafruit Its Bitsy, sottering tools, wood, wires, mechanical switched, keycaps, etc. Through out the project, I was following the guideline from the instructables website. The first step of the process was to sketch different designs for keypad; I sketched many different shapes for the keypad, like square, rectangular, circular, etc. I decided to move forward with the square design, because it was easier to interact with. Then, I build a press fit box, and laser cut it. After fitting the mechanical keys in the top portion of the box, I had to sotter them with the Itsy Bitsy. Sottering was the most challenging part of the entire assignment, because it was my first time doing it. In beginning, it did not work well, but with some help, I was able to sotter the keys with one another. 

First Sottering

After that, I connected Its Bitsy to the keys. Again, it was challenging because the Itsy Bitsy was very small, its ports were very tiny; I had to be very careful in Sottering, so that I don’t damage it. 

Connecting keys with Itsy Bitsy

Wired all the keys

After wiring all the keys, I had to do the coding part of the keypad, which was very straightforward, and went very smoothly. After coding part, I just had to assemble all the parts, and also attach Itsy Bitsy into the box. Sottering took me most of the time, but it was interesting to learn a new skill. The final product looked like this:

Final Product

As I mentioned earlier, this is a multi purpose keypad, and it could be used in many different ways. For my final product, I coded it in a way that first three keys were cut, copy, and paste, and the second set of three keys were select left, select up, and select right, and the third set of three keys were undo, select down, and delete. It turned out really well, and it was as I wanted it to be. I am proud of the entire product, and specifically how convenient it could be for the users. For instance, this keypad, the way I programmed it, was doing performing cut, copy, and paste commands with just one keys, while in the standard keyboard, users have to press two keys. It was also great that how it could be used in different platforms like gaming, data entry, etc. The final product turned to be great, and I was happy with it. Below is the video of the final product:

My first learning goal, was to push my creativity in designing the keypad, and do something innovative and helpful. I believe in most of the way, I have met my first learning goal. I tried to push my creativity in designing and coding aspect of the product. In the beginning, I had many different design ideas and sketches for the product. I designed it in shape of gaming joystick, two handed gaming controller, circular shaped keyboard, etc. I chose the square design because it could easier to use, and users are already comfortable using something like this. Also, the idea was that it could be used in different platforms, so if I could have chose the design for gaming, then it would not work in data entry or coding. Because of that, I moved forward with the square design. I also programmed it in way that it could be useful in entering commands, like copy, paste, etc. In the intractable’s tutorial, it was used for typing numbers. My goal was to make it very convenient for the users. This could also be very helpful because of its convenience and usability. This could also used by the elderly people, who have trouble pressing the combination of keys. I believe that the final outcome was innovative. In future, I plan to make it more innovative, by adding some extra features.

My second learning goal was to learn and do Sottering. Through out the project, I sottered a lot. In the beginning, it was a bit challenging, but, later, I got comfortable with it. I enjoyed the learning process. I had nine keys in the keypad, and each key had two terminals in it. So, I had to sotter eighteen times on the keys. I had two to sotter on ten ports of the Itsy Bitsy, so, in total, I sottered at least twenty eight times, through the project. I met my goal of learning to sotter, through sottering to create a final product. I am happy with the final product, because it would very useful to anyone, in daily lives, and it is also very convenient to use.

Through out the course assignments, I have learned many useful skills, techniques, and tools. One of the most useful things that I have learned is the usefulness of prototyping. In most of the assignments, I created many different prototypes for the final product. I learned that how much prototypes can be useful in understanding the design of the final product, and ways to make necessary changes in design. Another important skill that I learned was design thinking. In most of the assignments, we had to come up something different or new, and coming up with something like that required a lot of thinking, creativity, and ideas. The entire process helped me strengthen my design thinking skills. With the help of all the assignments and process, I have become comfortable with coming up with something new. I also loved making things and designing stuff. The process was time consuming, but, most of the times, I was satisfied with the end result. I have definitely developed confidence as a maker and a thinker. It would be very helpful in future projects and goals.

This course was very useful in making me think, from a different perspective. Through out the course, I learned a lot, and it would help me in future goals. I consider myself as a maker. I have learned so many different making skills and techniques, and also learned to apply those is real life projects. In the beginning, I thought that making is straightforward. However, through this class, I learned that it is not very easy, and it requires a lot of planning, thinking, iterations, time, etc., to finalize a product. To create something, it requires a lot of effort and commitment. I think that I am a maker, and anyone who is able to come up with an idea and implement it should be considered as the maker. I agree with the quotation of Papert that it is very important for any type of learning to be personally meaningful. If someone is attached to something, then learning about that is fun and interesting. I think all the assignments were in some ways hands-on and personally meaningful, which made the class, a great learning experience.

The making of The Dress

The Dress

Using vinyl I created templates for screen printing the pocket.

I used tissue paper to alter the pattern while preserving the original pattern in case I ruined everything.

The almost finished dress still needs a zipper, hem, & for the pockets to be to lined & sewn on.

But look at those sleeves! They’re crisp, beautiful, the right size & on in the right direction!

My proudest moment was the first seam around the neck. You can’t even see it anymore. But the stitches were even. I don’t mean straight. I mean even. You see, my machine was originally sewing weird, loose stitches, & it took between 20 min to an hour of carefully & methodically turning knobs & dials & threading & re-threading to create strong, even stitches.

Other than a finicky machine, I dealt with several other issues, a few of which were triggers for changing my design. Bicycle spokes were going to be too tedious & messy to screen print so I changed to birds. Then I discovered that my pattern was the wrong size & had to switch patterns, which meant redesigning my color blocking. But I persevered.

Over & over, I was grateful for my learning goals, which were:

1) I would like to learn how to do multi-layer screen printing through asking questions of staff and experimenting independently. 
 
2) I struggle with understanding patterns, so I would like to use this project as an opportunity to practice/learn how to use them.
 
3) I would like to afford myself the flexibility to simplify in order to preserve my mental and emotional health, and work on being willing to make adjustments to my project as I go along. 
 
These goals provided a framework for my learning and continually called my attention back to what I cared about most.
 
The first outcome was fairly straightforward and was accomplished in a fairly straightforward way. I asked questions of Emile, Amanda, and every other employee standing close by at the time I thought of a question. In this way I learned of the basic process of multi- layer screen printing including creating a vinyl template for each layer, sticking the vinyl on the screen, applying paint, setting the paint with heat, and cleaning the screens. I mostly experimented with my vinyl pattern, but I also experimented with color mixing and by creating my print. In this way I learned that skinny pieces don’t work well and that you should clean the screen between layers. My pocket was messier than I wanted it to be, but I had enough good patches to jimmyrig it. Honestly, I like the jimmyrigged pattern better than the original one.
 
The second outcome was far less straightforward to learn. Patterns are difficult and they seem to be written in another language. But I followed each step, asked my mother and Grandma questions, and made and fixed silly mistakes, such as sewing the sleeves on upside down. By the end, I got plenty of practice and can understand patterns a little better, but could by no means call myself an expert. Though I am very proud of those sleeves.
 
The third outcome was my favorite. This was the one meant to preserve my well-being. There were still some tears, anger, and frustration. But each time something went wrong, such as discovering my pattern was twice my size, I was able to say to myself “Thank goodness I built that into my plan.” Counting on adjustments took the pressure off and allowed me to continually simplify, or build on, my original plan. I learned not only to simplify, but also to trust myself. I seem to have proven myself trustworthy.
 
Throughout the course, I have persevered, except when I haven’t. I have triumphed, except when I haven’t. I have changed, except when I haven’t. I am still me. Sure, I can win against Inkscape in a fight more often than before and I have tinkered with a few more techniques and technologies than before. But by the end of a semester of struggling with things I’m not good at, I chose a project that played to my strengths. I don’t always do that. I often do what’s needed instead of what I want. So I guess I became more comfortable being and doing what I want. Am I a maker because sometimes I want to make stuff? I don’t know. I’m just me. Can that be enough? I think it can.
