Paper Circuits

Print the templates 

Star Wars Lightsaber

Harry Potter Wand

Grab the Star Wars or Harry Potter template and print it out using a double sided printer. If you don't have a double side capable printer you can print each side separately and either tape or staple them together.

Place the copper tape 

Starting on the back or inside, tear off some copper tape and tape over all the brown lines on the template. Try to make each run of copper tape just one piece. While the adhesive is conductive, it isn't as good as the copper itself. Take extra caution when making turns. I like to lay down the tape then deal with the turn by folding it.

LED 

Flipping over to the front, grab the LED. It has a short leg and a long LED. Stick it through the paper at the top of the Lightsaber or wand, with the longer leg on the left. Flip over to the back, and bend each leg over the copper tape. Peel a little copper tape back and over the leg, making an LED leg sandwich. Place a piece of normal tape over the legs to ensure a good connection.

Battery 

The battery has a smooth positive side and a bumpy negative side. Place it with the positive side facing down and the bumpy negative side facing up. Fold over the corner of the paper and secure with a paper clip.

Almost Done 

Fold the paper in half and press down where the switch is. The LED should light up. If you made the Lightsaber, you can cut a section off of a drinking straw to guide the light. It should fit snug over the 3mm LED.

Troubleshoot 

If your LED isn't lighting up, double check that your battery is in right way, the LED is in the right way, and that there are no breaks in the copper tape.
