No Sew Light-Up Cuff

We’re going to start today by making a simple no-sew light-up wrist cuff. Use the template to guide you.

Step 1

Cut a piece of felt that is at least 2 inches wide and 6-10 inches long, depending on the size of your wrist.

  1. On the right side, make two 1/2 inch vertical slits roughly 1/2 inch from the end of the felt to create tabs.

  2. On the left side, cut two 1/2 horizontal slits roughly 1/2 inch from the edge.

Step 2

Attach the components with foam tape.

  1. Attach the battery pack to the left side, slightly toward the top of the felt, as shown. (4a)

  2. Attach the LED chip in the center. Make sure the white negative side is facing right and the red positive side is facing left. (4b)

Step 3

Complete the circuit.

  1. Apply Maker Tape as shown, wrapping the negative side over and around the felt on the right side.

  2. Add extra tape on the left side between the horizontal slits and on the right side on the back of the tabs to ensure a good connection. (Figures 4c, 4d)

 

Step 4

Complete the cuff.

  1. Turn the switch to “On.” Wrap the cuff around your wrist. Place the right side over the left and slide the tabs into the slits to complete the circuit. (Figure 4e, 4f)

  2. Decorate your cuff in any way you like! (Figure 4g)

No Sew Alternatives

Traditional LEDs

Want to use traditional LEDs and a battery? Just gently bend the LEDs and attach the battery as you did for Paper Circuits.  (Figures 4h, 4i, 4j, 4k)

Multiple LEDs

Want to add multiple LEDs? Try a parallel circuit instead. (Figure 4l)
