Copper Tape Pop-Up Card-David Booke

For this project, I wanted to make a basketball scene. My pop-up features were going to be two basketball players and a basketball hoop. The plan was to use two red LEDs to put behind the backboard to make it look like the buzzer was going off. The inspiration for this card can be watched through this link: https://www.youtube.com/watch?v=eYHtgiRDWbQ

Before making it, I was slightly worried about making the parallel circuit and doing the wiring from the card to the backboard; I knew it was going to be messy and require a lot of planning. The tutorial provided on compass only featured one LED, so I didn’t think I’d be able to make it look as clean as that one since there was going to be two LEDs on my card.

The first time I tried cutting out the hoop, I forgot about that inner border around the backboard so it didn’t cut how I wanted it to. Removing all the details on the net and making it just a cone shaped black blob also took some time. It required messing around with the nodes a lot. With all the pieces cut out, I quickly realized that the hoop was far too skinny to stand up on its own, especially when it had LEDs on the top of it. I also realized that there was no way I was going to be able to hide the copper tape behind the pop-up like in the tutorial due to how skinny the hoop was. I decided to diagram my circuit and handle those problems when I ran into them. As you can see, I had some issues. My pop-up square proved to not be large enough to have all my tape running up and down it. If I were to do this again, I’d definitely choose wider objects. That way the card would look much better without the tape visible everywhere. Another issue I ran into was having the tape overlap each other. To remedy this, I created a bridge over some of the tape using some cardboard so there was no overlapping happening. It can be seen in the picture above as the blue square to the left of the backboard. Another problem I had was getting the hoop to stand up straight. I was so worried about getting the circuit to work that I neglected the aesthetics of the card. Despite all my issues, both the LEDs worked when the switch was underneath the tape flap. It isn’t pretty, but it works. I think I’m most proud that my circuit worked on the first try. That was thanks to careful planning and Physics 212.

Vinyl Sticker Project-David Booke

For the griffin sticker, I wanted to make a giraftle (giraffe and turtle.) It was going to be the head and tail of a giraffe and the body and legs of a turtle. Separating the entire giraffe into the two parts of it I wanted proved to be a bit more difficult than I expected. Messing around with, adding, and deleting nodes took a bit of getting used to, but eventually I had just the tail and head of the giraffe and the body of the turtle. Once I was ready to put them together, Inkscape force closed on me and I lost all my progress. I will definitely begin saving throughout my projects from now on to prevent this from happening again. Now I needed to save some time since I was missing the next instructions from Sara, so I just used the giraffe’s head and body of the turtle.  I like the way it turned out.

For the logo decal, it took me awhile to figure out what logo I wanted to do. Sara told us that our logo needed to be only two or three colors and simple. Finally, I settled on the Tiger Woods logo. Separating the colors using the “Break Apart” tool was kind of weird because it didn’t do anything the first few times I tried using it, but it eventually worked. With the colors separated, it was easy cutting out the two shapes using Silhouette. I decided to use red and black in honor of Tiger’s Sunday outfits. 

Using the clear transfer paper worked very well and made it easy to align the two components of the logo.

For my multi-layered final sticker, I was set on doing the Minnesota Vikings viking logo. There are a lot of intricate lines and small cutouts for it, but I decided it was going to be worth it in the end. Here’s a picture of the whole logo and its constituent colors broken up.   

I imported this image into Silhouette and traced each individual image once at a time and cut them out. I didn’t get to use the colors I wanted to for the vinyl, so Viktor ended up being a Scottish viking instead of a Scandinavian viking. Also, I couldn’t find any white vinyl, so his horns are gray instead of white. The first component I cut out was the black one, and I had a lot of trouble getting only the parts of it I wanted. I made a big mistake by taking the vinyl off from the paper and then trying to take all the little unwanted pieces out after with the sticker in my hand. For the other four components, I left the vinyl on the paper and used tweezers to take out the unwanted pieces. Also, once I was done with the black part, I put it back on the paper. This proved to be a mistake because transfer paper was no longer able to pick up the vinyl from the paper. I ended up having to redo the black component because of this. 

I really underestimated how difficult it would be to pick off the unwanted vinyl pieces. It took me at least ten minutes for the black and purple components each. I figured aligning all five components right on top of each other precisely would be difficult, but it wasn’t as bad as I thought. There is some misalignment, but all in all I think it looks pretty okay.

Name Tag-David Booke

I wanted to make my name tag look like a film reel. I’m really into movies, so I thought this would be a cool idea. I wanted to have two layers with the first being the outer canister portion and the second being the black film inside. My name would be etched in the second layer so that it can be seen through the slots of the first. I thought about making the outer layer able to spin but decided I’d keep it simple and just glue the two layers together. 

I used Inkscape for the design of my name tag. Choosing a film reel from the internet was a bit difficult because most of the reels only had four or five slots (not enough for my name to look good in it.) I ended up choosing a design with eight slots, so it kind of looks like a car rim but that’s okay. With eight slots, my name would look good inside the slots. The most difficult part of my design was aligning the letters of my name symmetrically in the slots. After some help, I used the Arrange tool in polar coordinates to align the letters. 

 

 

With everything designed, I need to choose materials and cut it out. I chose a metallic silver acrylic for the outer layer and a black acrylic for the bottom layer. My name being etched in the black acrylic can be seen in the picture below. 

With everything cut and etched, all I had left to do was put them together. I used the prong of a fork to carefully place super glue in strategic positions around the outer silver layer. Then I aligned the two layers and pushed down on them until the glue set. Below is my finished product.

I’m quite happy with how it turned out. I chose an old-timey looking font because I thought it fit the movie theme. The only bump I ran into was arranging the letters, but that proved to be simple with the Arrange tool. I’m not sure if there’s a way to remove the burn marks on the silver acrylic layer, but, if there is, I’d like to learn how to do that. I think that’d really clean it up and make it look better.
