Mobius Strip:
Hey. So here is the first circuit I made in class, it is a mobius strip (loop of paper, joined with a twist).
Materials:
-paper
-conductive ink
-conductive thread
-conductive fabric
-conductive tape
-resistive ink
-electrical tape
-3v battery
-LED
-clear tape
How it works:
The part where the paper joins has resistive ink, so the LED dims or brightens depending on the size of the strip. Here are some pictures…

Largest Loop: (Dimmest)
Smallest Loop: (Brightest)
Simple Switch:
This is the second project. A simple circuit on a 4 by 4 piece of paper.
Materials:
-vellum
-conductive thread
-conductive fabric
-electrical tape
-3v battery
-LED
How it works:
You fold the two opposing corners of the paper along the pre-folded line, and conductive fabric closes the circuit, turning on the LED, which changes colors =). Pictures:

Paper Airplane:
Finally the third circuit, which used an example from the pop up book. I used the lever, which you pull, and turns on the LED on the front of the plane…
Materials:
-vellum
-conductive thread
-conductive fabric
-electrical tape
-3v battery
-LED
-clear tape
How it works:
You pull the lever, which is one the right side of the plane, and conductive fabric closes a circuit on the inside of the plane, and the light on the front turns on. Pictures ahead:

And the videos for blinking lights and fading lights on the Arduino. =)
