For my pop-up card I began with brainstorming different ideas for the pop-up. I found a video of a pop-up flower card which I liked and thought I could use as my main idea. I took a piece of scrap paper with fire-like colors as the pattern on the outside of the card. Sticking with a fire theme, I used orange paper to cut out the multiple flowers and purposefully made them with pointy edges to enhance the theme. Next I colored the inside of each with a red marker, to give the flowers some color. I wanted my card to look clean so I chose plain white paper for the inside. I struggled with connecting the flowers in a certain way where they would open up connected in the center. The glue I was using was not strong enough leading to the individual flowers separating a lot. But in the end I was successful in making the flowers open up the right way. For the circuit I wanted the lights to shine through the flowers so I made a circuit on the fire patterned scrap paper and then cut out holes in the white paper for the lights to go through. My first attempt was unsuccessful because I realized that the lights cannot connect to the copper tape from under, leading the the lights not turning on. Therefore I remade the parallel circuit (with four lights) on the outside paper, with a switch on the left and a battery in the right corner. I also put the battery on a flap because I did not want the outside card to fold over. It was easy to resolve for I put the negative and positive copper tapes on the square piece and folded that over the battery. For the switch I taped a copper piece on the backside where when it is pushed it creates a circuit for the other 2 lights. And in the last step I connected the flower pop-up with the circuit card using glue. Overall, through my challenges I came up with a card similar to my idea but if I had more time I would've loved to add more to the design.

In class we were given 3 pieces of paper outlining how to make circuit stickers. Using a copper wire strip I traced the tape onto the lines. Making corners was difficult but as I practiced my corners became sharper. Next I chose the LED light (either blue, red, or yellow), and stuck them on the traced triangles. After putting the copper tape and LED on the papers, all I had to do was grab a battery and press it between the paper as shown below. I made sure that the positive and negative sides were on the correct outline. In the simple circuit the LED light is between a negative and positive strip that when connected (with the battery) send an electric current around powering the light. In the switch circuit the copper strip opposite of the gap (shown below) controls the light because when folded it completes the circuit. And when unfolded it breaks the circuit. In the parallel circuit there is one negative and open positive strip aligned in a way that when it is connected to a battery each light is reached with energy to power it. In my exploration I had no errors. But I observed in some that when the light wasn't turning on it was usually because of a gap or rip in the wire strip.
QUESTIONS
How do the two circuits (in the second to last paragraph) differ? Why is a short circuit bad? What is the difference between a parallel circuit and a series circuit? |
