Copper Tape Card – Rebecca Tu

  I was inspired by the fact that we can use origami for this project. When I was younger, I used to love making paper stars and cranes so I wanted to incorporate my limited origami skills here and have the chance to create some stars again. When I think of lights, I usually think of Christmas so I decided to create a starry background and add a pop up snowflake and snowman.

I faced a lot of challenges when making this project. I went through this tutorial (https://docs.google.com/presentation/d/e/2PACX-1vRciVXsTLiyo8EM5m1t7bUaiPtwTFNSI9OpYfcEo7Phnc82i-A7u9maGM8dx7zhUi7v1Ot_pXWt7wox/pub?start=false&loop=false&delayms=60000&slide=id.p) until I reached a point where I didn’t understand what was going on towards the end. I was lost about where to place the copper tape on the LED lights and how the circuit should end up looking like. 

Apparently in class, when I did the basic light card, I did the wiring wrong even though it still lit up. 

Here you can see that I didn’t actually create a parallel circuit.

However it somehow still lit up here:

I learned that for my pop-up card that from the positive battery side, I had to extend the tape to the other side of the paper and add a copper tape to that tape from both positive sides of the LED lights. Then I had to connect a copper tape to both negative sides of the LED lights and connect that tape to the switch on the right. Only then did the lights light up. Originally, I had it so that there was just one long tape that went from the positive side of the battery straight to both positive sides of the LED and then back to the switch. This was wrong and nothing lit up.

If I had more time, I would’ve made something prettier. I was just so upset that my circuit wasn’t working and I was so frustrated with trying to get it to work that when I was finally able to, I was exhausted.
