Introduction: Sewable Electronics - Make a Bracelet

A wearable is a piece of technology that you can wear.

A few years ago I was proposed to design a wearables workshop that should be cheap so it could be made massively and easy to be done with children.

There are a few wearables projects based on Lillypad and other electronics, but we decided to make it open-source and cheap to produce locally.

Step 1: Materials & Tools

You will need the following standard materials:

  • some felt or any other tissue
  • a standard LED (I use RGB blinking LEDs) that you should mark the negative leg (any marker pen will do) and then twist the two legs in a closed loop so you can sew each leg.
  • 3V coin cell
  • hooks & eyes clasp (on chrome finish because it must be electricity conductor).

And also some special ones like:

  • Conductive thread. This is not easy to source but we are using a thick thread similar to knitting thread.

The basic tools to use are:

  • Scissors
  • Needle
  • Pliers

Step 2: Step 2: Cut the Felt to Size

Step 3: Step 3: Sew the Battery Holder

Step 4: Step 4: Sew on Half of the Switch

Step 5: Step 5: Sew the Positive Pole of the Battery Holder

Step 6: Step 6: Sew the LED

Step 7: Step 7: Sew the Negative Side of the LED and the Other Half of the Switch
