No Sew Light-Up Cuff

45-60 min


Ages 8-13

What Will You Learn?

You’ll take your knowledge of circuits and use it to create a soft circuit with fabric. First, we’ create a light up wrist cuff, and then you’ll make and customize your own wearable!

This project is a sample from our Circuit Scouts Kit, available in the Maker Shed with all the materials you need, a guidebook, and educator’s curriculum.

Make the 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)

What's Next?

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.

Multiple LEDs

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

Maker Camp June 14, 2021
Maker Camp is a do-it-yourself online resource to help leaders like you organize a summer camp that engages children in making. Our goal is to provide you and your campers with the inspiration and the helpful resources, along with many possible projects to fit a wide range of interests and abilities. The idea is to focus on making as a playful, social activity. Maker Camp provides enough support for anyone to get started. Making provides experiences that help children become self-directed learners and good problem-solvers.
