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.
