Copper Tape Card Assignment

Before beginning your project:

The third project is to make the copper tape 3d card. My lab section is 2/13 and the next day is the valentine day. I wanted to make a 3d pop-up card for valentine day that I could give to my boyfriend. The topic of my copper 3d card is love and heart. Instead of just making 3d card by cutting the background paper and sticking the 2d picture, I wanted to make a 3d card by sticking the 3 dimension paper on the card. I have all the tools that I need to make 3d card. I wanted to use pink light and green lights and there were these color-light bulb. I have the knowledge of the circuit. However, It was quite difficult to design the new circuit for my own card. I was so excited to make it. I often make the card for my family or friend’s birthday. I think it is really cool because I could use the light. One thing I worried about was that if the circuit does not work. Since the 3d heart might take a long time to make it, I would be depressed when I have to make 3d heart again because of all settings  for circuit do not work after I stick all together.

 

While working on your project:

I saw multiple LEDs parallel circuit video to make sure I am doing in the right direction. This video might help other peers to design their own circuits. Since my card tried to avoid displaying the copper tape at the outside, I should check before I stick the two layers of paper. If you do not check whether the light turns on before sticking the two papers, you should start all over again. Instead of put the LEDs on the background page, I put my LED and circuit on the bottom and made a hole for LED; so that other people could only see the LED lights shining right below the 3d heart. I also put two green LEDs in the corner so that it seems like there is a light from the cupid’s arrow. One thing I should be carefully when I work on green LEDs is that I should make the top layer not touch the part of circuit. For the green LEDs, I used parallel for making the light as bright as only one LED. As I mentioned above, I usually do stuff like this at home. It was worthy of making my own card to precious people because it seems more heartfelt gift.

After finishing your project:

I think I need to be more flexible to design the multiple LEDs circuit. I separate the two buttons for two LEDS to turn on. If I had more time, I would make more fancy design card. Since I had so many works this week, I could not fully engage in the copper card making. For this assignment, I do it all by myself. I am proud of myself:) I decided to finish my project because of the time. My goal was to make 3d cards with three LEDs and the design of cupid and heart. My final product my goal and I am satisfy with the card design. My card works for all three LEDs. One thing I had a change in my final product is that I added “LIKE” with the copper tape for design and also added the heart arrow in the background. Describe a “big moment” that moved your project forward. At Sunday dinner, I was doubted I could finish this project with my goal met. It was so difficult to make 3d heart and make it stand. Also, I took long time to consider the design of the multiple LEDs circuit. After I finished making the 3d heart, then I started to make the 3d card delightly having the self-confidence. Unlike the previous assignments, this project took more time. I was often frustrated to make the 3d heart and struggle with not-working-LEDS. Sticking small parts of heart and arrow together was so frustrated because of my shaking hands. Although, it was tough time to finish in a week, all the process was fun. I have a fun time because I made what I want to make.

Copper Tape Card – Andrew Holler

This week the INFO490 Makerspace class made copper tape crafts. I thought I had an idea of what this was about before attending lab. I’ve seen videos on various social media sites of circuits and electronics that are made by taping. I was definitely expecting more of the classic circuitry feel from the projects but was pleasantly surprised by how different copper tape circuitry is. I imagine these would be (and are) a fantastic, cost-effective education tool for any age learning about electronics and circuitry. It takes little background knowledge and results are quick. Personally, this week had me a bit worried because I was very crunched for time. I’ve been busy with some tough assignments and yet found time to successfully complete a makerspace project.

The concept behind copper tape circuits is seemingly simple. Connect the positive side of a battery to the negative side using the tape. In between the loop you can put any sort of component that you wish to receive power from the battery, just make sure to create a +- loop. Challenges arose when I attempted to put LEDs in a circuit series instead of parallel. In series, if one of the LEDs fails it will break the circuit and none light up. Conversely in parallel, if one fails all the others will still work. I also found that copper tape circuitry requires a fair amount of dexterity with tape, folding, and tight spaces between paper. My final bear project had some issues due to a lack of said dexterity. I could see this being a fun and cheap hobby at home but, I haven’t and don’t see myself working on it at home.

As I mentioned before, I was crunched for time. An upcoming artificial intelligence deadline was constantly putting pressure on me. I decided to follow the tutorial posted to complete my copper tape card and it helped me finish surprisingly quickly. I ended up customizing it for myself a bit and I used the silhouette cutters to make trees and a bear. I even ended up using the negative cutout of the bear as a background instead of throwing it away. I had trouble when it came to the LEDs lighting up and it was very finicky. It was also hard to see the lights with the classic LEDs. Using the sticky ones probably would have produced better results. With more time I could probably perfect the connections and lighting of the bear.

I had fun with the quote card assignment, too. Firstly, no, I am not that talented at drawing. How did I draw these decent looking hands? The answer lied on my phone, or at least the paper did. I laid it on my phone and traced a zoomed in picture of the hands. It was a fun, clever way of getting the “Love” part of the quote I wished to convey and I liked the results. The “light” part of the quote came in with the lights lighting up the darkness when you touched the hands together as shown. It’s probably what I’m most proud of in this learning block. Another week of making down. Can’t wait for 3D printing!

Copper Tape Card Project – Andrew Sun

For this week’s copper tape cards, I decided to honor the recent launch of the Falcon Heavy by making a card depicting Elon Musk’s Tesla floating through outer space. I chose to have the car as the popup in the foreground, with Earth and some stars in the background. For my LEDs, I would make the stars shine when the card was opened. I originally also wanted to use a LED for the headlight, but the area turned out to be too small to have both the positive and negative tape go through.

The first challenge I ran into was making the LEDs shine through the black background paper, which absorbed all the light. To solve this, I added another layer of paper, and cut a star-shaped hole in the front layer, in the same spot as the star paper. This let the light shine through, and also had the cool effect of making a bright area in the middle of the star, making it look kind of like the light was fading out the further away you were from the star.

Wiring the circuit was a little difficult, since my LEDs were on the background layer instead of the cutout. To make the circuit for the stars, I had to pass the copper tape through the “cut-in” area. One problem I ran into was getting the circuit to work. As it turns out, the battery doesn’t contain enough voltage to power both LEDs in serial. I had to rewire the circuit to make the LEDs connect in parallel. A quick tip: before laying down the circuit, test that it works by putting the battery on one side and using the unpeeled copper tape to connect the other side, so that you don’t have to ruin the paper by removing incorrect tape. Surprisingly, the switch worked really well – I didn’t need to hold it down at all. However, the connections to the LEDs were a bit loose, so I had to use some extra force to get it to stick properly.

In hindsight, I think I probably should have used the vinyl cutters from last week to make the shapes. Most of my shapes were cut out using scissors, but there were a lot of narrow areas on the car and Earth. I ended up using a razor knife to cut out those areas, which turned out a bit messy.

Copper Tape Circuit Origami – Eric Hallstrom

I was inspired by the quotes we got in at the lecture, it was actually helpful in order to start designing. I started of with the quote for the first project. For the second part I was developing the idea that Facebook owns and got ton of data about us. I wanted to make 3D origami for the last part. I was thinking, how hard can it really be with origami (never done it before) but gosh I was wrong, It’s really hard! It was fun to play with circuits and copper teip really brings electronic down to the most basic thing ever, just flow in current.

 

The best way to explain this to a peer is to just try it out and play with it, eventually one will figure out how it works even if the lights are a bit sketchy and not 100 % perfect. The biggest failure during this project was that I underestimated origami. You need to be very patient and put a lot of time into details. Both time and patient was something that I lacked for this project. I think the knowledge of paper circuits is extremely good to explain how electronic actually work for people who don’t know. So in a broader sense this project was really important and I will hopefully get to use this to show how most of our society works in terms of technology. I’ve never done this kind of paper circuits. The only circuits I’ve done is with Aurdino. This project really removes the magic of currency flow that arduino kinda hides. It would be cool to have more components to the paper circuit and like measure currency in the circuit or something.

To do origami. I mean, I wanted to do a chest at first and I found a tutorial on how to do it. But it quite fast turned out that this was not a good thing for a first time origami project. If I had more time I would put more time into origami and the details of it. I would also get decent paper because when I was trying to do the chest I think my paper ripped aparat like 4 times so I had to start over each time. The most insirpiring thing was the origami community. The stuff that you can make out of paper is awesome to see and most of the stuff was really mind blowing, like the 3D origami where they put tons of small modules into one.

 

I got really great help from the assistances at the fablab and also Youtube was a big help.

To point that made this project completed was when my origami chest ripped apart for the 4th time and I had to decide that this was way over my head and I had to go for something simpler. The biggest mistake was to underestimate origami and how hard it actually could be. My goals for this project kinda failed because of the difficulties and limitations of time I had for the last part. Initially I wanted to make a treasure chest that had LEDs inside so when you opened the chest, it would glove but that didn’t really happen.

 

The only thing that went fine in this project was the technical part of the circuits, it was no problem to make serial- or parallel circuits but the funny thing is that this doesn’t matter because the end product turned out really bad. The three unexpected things that happened during this project was that origami is really hard, or at least I suck at it. Copper teip actually is cool and works really well. And utilizing the given reflection questions is also actually good.

 

The big moment in this project was that when I realized my origami skills is not going to make it for now so I had to switch to a simpler design. I had to give up for the initial design idea I had in mind. This made me switch to a less complicated idea. The most frustrating part was that the paper I used, was way to thin because it ripped apart several times.

Copper Tape Circuit Origami- Edbert Linardi

This week project is about creating a LED Circuit based on paperboard. For the first two in-class assignment, we made two basic boards. The first one has no images. On the second boards, I picked a quote and drew a simple cartoon based on the quote.

 

The quote is saying “The only whole heart is a broken one because it lets the light in.” – David J. Wolpe

Based on this quote, I was inspired to draw a couple with broken heart between them. Then, I put the LED on the heart. Besides, I wrote “Let the light in”, and used it as a switch to turn the light on.

For the third assignment, we created a 3D objects with LEDs on it. My original idea was to make a heart shaped origami, since the Valentine’s Day is coming soon. However, I failed since the paper was too thick, while the heart origami requires a lot of bending. Therefore, I needed to get another idea. I chose to make a origami bird. I followed the tutorial on https://www.origamiway.com/easy-origami-bird.shtml. I personally do not do origami at home, since I’m not an artsy person. However, I want to make a origami circuit because I was inspired by a short movie on Youtube.

The process of making the origami bird was not quite difficult, but also not that easy at the same time. I was able to follow the steps by making some corrections. Initially, I made a paper-bird that was too small.

It was difficult to put LED on this mini bird. Besides, it will look  not that nice.

Then, I made another bird. This time, I picked a larger paper.

Some pitfalls that others can avoid while making origami was not folding the paper carefully. Origami requires a lot of attention to detail. If it was not folded carefully, there will be some gaps between the folds.

 

After done folding the paper, I drew the circuit. It was not too tidy since I only used it for guidelines for sticking the copper tape.

I chose to put the LEDs on the bird’s eyes.

Initially, the orange LED that I chose cannot be turned on. I had to change the LED to the pink one.

I put the switch on the body, so when the body or wings are touched, the eyes will be shining.

This is the final product.

Finally, there are lots of things that I still need to learn to create a better LED-origami. I think the circuit design was nice. However, the problem is on the origami itself. My foldings were not really tidy. Besides, I believe I need to use a real origami paper for a better result. Using an ordinary paper will not be enough to make a pretty origami bird.

Something that I like about my origami bird was it has pinky eyes shining brightly when it’s touched.

Foxy Copper Tape Assignment

This week in Makerspace, we worked with copper tape circuits and created three items.

  1. Basic paper switch (picture 1) – I think this might be my first time (maybe second) creating a paper switch. I don’t think I’ve ever used copper tape before. Albeit simple, I was really happy when my LED light lit up.
  2. Picture with two LEDs (picture 2) – It took me a bit longer to understand how parallel circuits work but I eventually got it.
  3. 3-d paper object with 2 LEDs – This project took way longer than necessary because I made a lot of mistakes…

We had a choice between a pop-up card or origami for this project. I wasn’t sure what I would do with a card so I thought I’d do origami. My idea was to have red LED lights for an animal’s eyes, and upon squeezing its tail, the eyes would light up because it is mad at the person. I looked on Youtube and saw a cute fox origami project. I’ve not worked in origami in many years and my inexperience really showed. I spent a long time trying to create a complicated fox piece but gave up after 20 minutes. I found an easier fox to make but that still took me a while (picture 3). After I completed the piece, I penciled in (while it was still 3-dimensional) where the LED lights would go, where the break in the circuit would be, and where the battery would be placed. After unfolding it, I planned out the copper tape circuit and piece placement.

The parallel circuit path proved really easy to plan (picture 4). I taped down the entire circuit and tried connecting the break. It didn’t work and I started panicking. One of my friends told me that the adhesive side of the copper tape was not very conductive. I peeled off the copper tape very carefully and twisted it so that the non-adhesive side would touch the LED stickers. It worked! Great. I folded the fox back up and tested it. The lights worked but it appeared that the LED stickers were not facing towards the sheet of paper but away from it. I had totally forgotten about that important factor. I think I was starting to lose it at this point. I undid the fox and tried peeling all the tape and stickers again. This time, the origami paper started coming off with the tape. It became a mess and I restarted. After another 30 minutes of folding and laying out the circuit path, I finally finished (picture 5 and 6). Next time I do a project, I need to plan more carefully.

Copper Tape Circuits Project – Nick Desai

Our third assignment was to make a 3D paper object with copper tape and LEDs. This was super fun, because I’ve played around with circuits before, but never with these kinds of materials. In the intro class, we had an introduction to circuits, and we made quotes with light-up areas powered by circuits underneath. I chose a quote about a bat by Shel Silverstein, and made the bat’s eyes glow when you pressed the quote. The in-class project was fun – I haven’t worked with crayons in a long time, so it felt like being a kid again!

 

For our more advanced week project, we had to either make a pop-up card or an origami object that incorporated lights. I always like looking at other people’s origami stuff, so I wanted to make something with origami. To see if that was remotely feasible given the fact that I have very little previous origami experience, I tried my hand at making a paper crane out of an old assignment sheet. It went pretty well, so I got some construction paper from the lab, trimmed it into squares, and made a bunch of different animals. One difficulty I had working with construction paper is that it’s kind of thick, so areas where a lot of layers sit on top of each other tend to be thick, and folds don’t press down quite as nicely as you would want. It would have been nice to work with actual origami paper. Another problem is that construction paper tends to have one direction along which it really likes to tear, so you’ve got to be careful when you’re pressing folds flat that you don’t accidentally ruin your paper (which I did 🙁 ).

After I made the crane, I was thinking about how to incorporate electronics into it, and thought of making a display case for all the different animals, where the case had the lights and the animals themselves acted as switches, so putting an animal on the case would complete the circuit and cause the case to light up. I tried it with the crane first, putting copper tape along the bottom of the model, and it worked well enough that I did it with the rest of the animals too. I then made a box for the animals to sit on, and put the battery on the inside, with tape running to the outside where the LEDs were mounted.

Then I tested the crane on the box.

It worked all right, though I had to press down to get the circuit to complete. That proved to be the case with the rest of the animals too – I had to cover every part of their bottom parts with tape and press them down to get it to work.

In the end, to take the result pictures, I had to kind of cheat and use a bit of extra tape to connect the animals to the circuit. But I like the way the result turned out!

(There’s a stingray, an attempt at a dragon, a butterfly, a crane, and my favorite, the dinosaur)

I like how the light reflects off the folds in the paper, especially on the last one! Though it was kind of a pain to get the circuit to connect, and if I were to do this again, I would have put the switch on the box itself, and weighted the animals down so they pressed a switch flat, which I think would have been more reliable.

Project 3: Copper Tape Origami

This week we worked on paper circuits! This assignment was different than previous ones because I was more fixated on the insides of the product, whereas in earlier projects I was more concerned with the aesthetics and (social) impact of the product. The basic circuit card and 2 LED card were a good way to get comfortable with figuring out how exactly the circuit would work. Sketching out the path first was helpful.

The final product was tricky. I chose to go with a paper crane, since I’m comfortable with the folds and thought that would give me an advantage. However, figuring out the route the circuits would take & where to place the switch proved a great challenge. I knew I wanted the switch to be activated when I pressed on the bottom folds of the paper crane (this way the wings of the crane would light up when I flapped them from the bottom). However, my initial routing placed the switch at a location where only one LED would be cut off. At the second attempt/re-route, the folds kept the switch in place, so the lights would always be on. After three revisions (at some point I just put the tape down and made demo circuits to understand how/why the switch works), I got the circuit and switch to do what I wanted it to do, which felt good! I’m feeling more comfortable with the re-iteration aspect of these projects.

Project #3: Copper Tape Light-Up Card

For this lab, I was thinking to make a light-up card for a recent popular game in Asia, called 旅かえる. The game is about a travel frog, and player acts like the parent who helps pack its package. So the basic idea is that the frog’s house lights up when it’s at home.
The first problem I have is that, in the game, we need to swipe left or right to get the whole scene. So I screenshot 7 images of the front door, and make it into a wide-angle image. I first thought of the panorama photo, and use an online tool called “Dermandar”, which generates both panorama photo and wide-angle photo. I found out the wide-angle photo is what I actually looking for.

And then, I measured the distance between the entrance and the window, in order to make the circuit light-up in the right place. After I finished the circuit, I cut the window and a leaf, and use another paper to make a new window and a leaf so the light can show.

After I finished everything, my friend asked me did I draw everything, I said, no, I printed it. He said if I drew it, it will be more amazing. I also notice that I can make it more 3d if I do paper-cut work on its house and leaves. I am not satisfied with what I did this time. I am thinking about doing a better one later.

Project 3: Copper Circuits

Design-

From the start, I wanted to make a pop-up card (style thing) with a scene from either movies or pop culture. I considered several options, before finally settling on the climax of Harry Potter and the Dealthly Hallows, where Harry faces Voldemort for the final time. This lent0 itself quite well to the sort of project I wanted to make, with a red LED for Harry’s wand, a green LED for Voldemort’s, and a yellow LED for the sun peaking through the window (that didn’t make it into the final version)

 

The Finished Project. Ignore the name tag/fallen fighter at the bottom

 

Rather than try and print out designs onto paper, then cut them out, I decided to go for a more stylized approach, with the characters being blank silhouettes, black for Voldemort, white for Harry, and Gray (later amended to blue) for the bystanders. Not the most subtle coloring, but one that I felt I could execute on, and make well.

I had three major goals with this project (in addition to looking good)-

    Make the electronics as reliable as possible

    Minimize the visible wiring when the card is open

    Make the card sturdy enough to survive transport, and open well

 

Fabrication-

I had had quite a bit of trouble getting my first couple of copper tape circuits to work, so ensuring the reliability of the connection was foremost among my concerns. I also did not want a lot of exposed wiring in my finished product, as I felt that detracted from the overall aesthetic.

To get the silhouettes, I found images on the internet, converted them to vectors, and cut them out with the silhouette, in a quite similar process to the sticker cutting. My major mistake here was leaving the blade at the vinyl cutting distance, rather than lowering it. This unfortunately left an outline on the cutting mat when i was done, where the blade bit into the adhesive.

 

Mooks all cut out, with harry in the corner

 

My original idea for increasing stability was to glue multiple sheets of paper together once cut out. However, James recommended that I use chip board as backing, and that worked so much better. It matched the background paper color I had chosen, as well, so it did not matter that the cutout wasn’t perfect (I had to do it with scissors). The chip board was necessary, as I planned on attaching the LEDs to the pop-out sections of my card, those sections needed to be able to support the weight.

Harry and Voldemort glued to chip board

Papercraft complete.

The chip board served two of my main goals. It both made the card far sturdier, while also giving a way to easily hide wiring, because there was now a paper layer, with chipboard behind it. So, by routing in between the layers, I could hide it, except around the switch and battery, and near the LEDs.

I had faced two major difficulties in my first couple of tape circuits. The first, was that I had trouble sticking the LEDs to the tape. The second was that the sticky side of the tape was not very conductive, so joining separate pieces of tape often caused the circuit to open.

To solve my first problem, I decided to solder the LEDs to their copper tape. This was an especially good solution, as it not only ensured that the LEDs would have a strong connection, it also held the tape to the LED far more strongly than the adhesive could, which came in very handy when mounting the LEDs.

The LEDs, Soldered

To solve my second problem (how to attach separate pieces of tape without sacrificing conductivity), I came up with a method for making double-sided “band-aid” copper tape pieces. I cut out one long, and one short piece of copper tape. I then stuck the two together, sticky side to sticky side, and placed this piece on top of the joint, so that the short piece was in contact with both of the pieces being joined. The extra length of the long piece allows the band-aid to stick, while the shiny side of the short piece bridges the connection between the two pieces.

A copper tape “band aid”. The short piece is in the center, leaving both ends of the long piece sticky

Thanks to the soldering and the wire band-aids, wiring of the first two LEDs went smoothly. However, here is where I found that, even with two batteries, my green LED was far more dim than my red. In light of this, I decided not to add the third LED, which would have been behind one of the background windows, and acted as the sun. Adding a third LED, I feared, would further dim my already dim green LED.

Wiring finished. Just need to glue the LEDs to the pop outs

Here also arose the issue of the switch. I had to run a tight balancing act with regards to it. I used a copper band aid on top to facilitate conductivity, however the switch still had an issue where if the band aid was loose on top, the connection was spotty, while if it was tight, then the switch wouldn’t move in and out when I opened and closed the card. I experimented with several tab lengths, tab thicknesses, and band aid looseness/tightness. In the end, what I found worked best is to have a tight switch, and have the tab not enter all the way, instead being held against the copper band aid (see my final picture). This was where I failed in my goal to make the electronics reliable, because my final solution, while adequate, is somewhat unreliable. Sometimes, I will open the card, and the lights won’t turn on.

 

Aside from having to scrap the third LED, and having a somewhat unreliable switch, I am quite happy with how the project turned out. I had never worked with papercraft before, and found it rather fun. I am quite proud of how the scene overall turned out. Even without the LEDs, I think it looks good, and the chip board will help the pop outs stay rigid for far longer than regular paper would. Were I to do this project over again, I would definitely have used actual wire for most, if not all, of the electronics, as well as redone the switch. The copper tape was finicky in its connections, and often difficult to work with. As far as redesigning the switch, I think one possibility that would make it better would be to have the contact surfaces be vertical (so opening the card pulls them directly together), perhaps in addition to the horizontal surfaces I tried.

Assignment 3 – copper tape circuits

For the third assignment we had to make copper tape circuits. This assignment was pretty different from the past two assignments since it was a lot of hands on / touching, whereas in the previous projects the main bulk of the work was done through a computer software. I was looking forward to this project since I don’t know much about circuits (zero knowledge!!) and I was excited to learn more and feel like a real engineer 😉 

For my quote inspired picture I chose to use a quote by Leah LaBelle that I found online. The quote read “Work hard for what you want because it won’t come to you without a fight. I wanted this to be a fun scene, since the first part of the assignment with the one LED I worked on in class was pretty serious. I began by building the circuit first. I learned that taping EVERYTHING down is the most important step. 

Making the circuit itself wasn’t that bad, but I had to restart so many times because I couldn’t get a good connection between the battery and the tape, the tape and the LEDs, etc. I ended up building the circuit and then putting a clear tape over everything on the circuit to make sure that it would connect.

I drew a person finishing a race with a STOP sign as the switch. Drawing the picture was really fun, since the everything but the eyes were free for me to create whatever I wanted. 

For the final part I decided to go for an origami and created a scene in the background.

I did not take into account the thickness of the paper, so the light didn’t show through. I was really disappointed in this, since I had imagined a really pretty scene for the finished product. I imagined the background to be a washed out dark blue, with two bright objects floating – the ship sailing towards the treasure chest. Putting the LED inside the objects would definitely have solved the problem.

Fortunately the light shows up in a dimly lit room at least, and I’m pretty happy with the finished product! I did not glue the pieces onto the board because I wanted to demo it in class and then tape the pieces flat to the board, so I can hang it on the wall of my room afterwards for a decoration at night!

Project #3 : Circuit Project

This project was very fun! I didn’t know copper tape existed (I assumed if we wanted to play with circuits we used wires)!

My first circuit with a switch was of a quote from Lord of The Rings and I placed the light as the star leading Gandalf and the dwarfs up a mountain.

Quote with switch circuit.

 

For the 2nd project, I used both a parallel circuit and a series circuit to make two lights work. It was tricky because I had to remember which way the current runs and make sure everything is taped well together.

A parallel circuit (ignore the original sketch of the circuit)

My 3D project was of a cat playing with a laser. This one was tricky because I had to play around with how to organize the circuit. Initially, it did not work. But I replaced the battery and re-tape the tape and it worked….occasionally. I drew the cats first then I tried to figure out the circuitry. It didn’t work the first time but I replaced the tape and got a new battery.

First attempt at circuit for 3D Project.

2nd Attempt with replaced battery, worked!

Final product with new battery test; worked!
