This project is a wearable jewelry switch with two rings, made out of aluminum bands (metal) and wrapped in copper tape, that interact with one another in a heart-shaped parallel LED circuit. Everything will be on construction paper and powered by a 3V coin cell battery. The rings are the only things that lift up off of the paper so that they are able to move and connect to close the path/circuit. Instead of traditional wires, fabric tape is used to stick everything onto the paper and to connect the battery, LEDs, and conductive thread to the rings on each side of the circuit. The conductive thread is less restricting and helps to press the rings together for the user more easily. Also, the thread assists to connect the rest of the circuit (on the paper) with the rings. The LEDs will be placed on the positive side of the circuit. When the wearer presses the two rings together, the fabric tape paths are bridged, closing the circuit and lighting both LEDs. When the rings are apart, the circuit remains open and the lights are off. The project emphasizes touch and gesture which means the human body becomes part of the circuit. Light is produced only through intentional connection. The gesture symbolizes friendship or some sort of connection/relationship. This design merges wearability, interactivity, and visual simplicity using readily available materials. 

Sketch:

Materials:
*3V Coin Cell Battery
*Aluminum Stamping Blanks (make 2 rings)
*Copper Tape (wrap around rings)
*Conductive Thread
*Fabric Tape
*LEDs (2)
*Construction Paper (Board)

Instructions:
1. Bend 2 of the aluminum bands into ring-like shapes and wrap copper tape all around them.
2. Tie a long piece of conductive thread onto each of the rings.
3. To create the negative side of the circuit, make a half-heart shape in the middle of the construction paper by using the fabric tape and sticking it onto the paper. Make sure the construction paper is portrait and vertical. At the top of the half-heart, tape down the end of the conductive thread (the side without the ring) that’s attached to one of the rings.
4. To create the positive side of the circuit (the side with LEDs), at the bottom of the half heart put some fabric tape over the coin cell battery on the positive side and stick the battery/fabric tape onto the paper. Make sure the negative side of the battery is in contact and on top of some of the fabric tape from the negative side of the circuit. Start to make a half-heart shape again with the fabric tape, but once you get to the middle area of the half-heart, your gonna make a smaller half-heart shape at that corner. Create a break somewhere in the smaller half-heart and add in one of the LEDs. Make sure the longer leg of the LED is towards the battery and the shorter leg is towards the top with the rings. Finish off the larger half-heart for the positive side of the circuit and at the top of the larger half-heart, tape down the end of the conductive thread (the side without the ring) that’s attached to the other ring.
5. Lastly, finish off the other side of the smaller half-heart on the positive side of the circuit, so that it creates a full small heart shape at the corner. Create a break somewhere again in the smaller half-heart on the other side you’re currently working on and add in the other LED. Now, you should have a small heart shape with LEDs on each side at the corner of the positive side of the circuit, and a overall heart-shaped circuit with the battery at the bottom and the rings with conductive thread at the top coming off of the paper.
6. Now that you have the full circuit, test it out and make sure it works! This is the fun part 🙂
