12-Hour Bracelet

For my 12-hour challenge, I built a simple circuit bracelet with an LED, 3V Coin cell battery and a 10K resistor. Lately, I’ve been interested in way to incorporate the circuitry of wearable tech into the design instead of always trying to cover up and hide it.

Sailors knot bracelet with LED

The result is a sailors knot braided bracelet that uses the wire (purple) to complete the circuit. The LED is located in the middle of the carrick bend and the battery and resistor is located at the back.

The basic knot. LED is attached to these wires.

I’m wearing it today for 12 hours!
