How to make a Heating and Cooling Jacket

Step 6 LEDs

You will be using the tri-colored LEDs to help tell you the temperature of the body.

Sew three LEDs on the outside of each of the arms of the actual jacket shell.

1. Sew all the positives to the positives of the three LEDs on the arm

2. Sew all the blues to the blues and then all the reds to the reds. You do not need the green port.

3. Then to connect the LEDs to the Lilypad.  You will need to sew in snaps to the inside of the liner and shell of the jacket. This way they will snap together. Each snap should correspond with its own lead. 

4. One side of the snap will be connected to the Lilypad in the liner, and the other side of the snap will be connected to all the LEDs on the arm. Use a set of snaps for the blue, one for the red, and one for the positive.
   • See the photo for more information, the larger snaps on the bottom of the collar are the three used to connect the LEDs. The two others are for the solar panel.

5. For the purpose of protection and light diffusion, sew on top of each LED a half of a ping-pong ball. It is easiest to pre-poke the holes with a thumbtack. In addition, a sewing hoop will help you keep the fabric taut.
