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…

Open:

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:
