Midterm for Computation Craft 

Beacon is a accessory that emits a loud alarm when the wearer triggers (closes the circuit) the sensor with a metallic ring.

I wanted to create a wearable that could possibly interrupt an attack.

Instructables Link (in progress)

Materials List

Alarm: Piezo Butter, Copper Pipe, Copper Tape, 9Volt Battery, Conductive Thread, Resistive Tape, Wool Yarn, Solder

Light: Fair Wire, 3V battery, 3V battery holder

This is an image from the prototyping phase of closing the circuit between a piezo a necklace piece (copper piping), and a 9V battery with needle and conductive thread.
