Step 1. Get a cheap black bra to customize. Step 2. Use an Adafruit Flora Arduino wearable board, a photocell detector sensor, X-wing and Death Star appliques, and make a Star Wars LED Bra that makes R2-D2 theremin-like noises. Whew. Okay, it’s a tiny bit more complicated but those are the basics as written by Instructables user caitlinsdad. He’ll walk you through a step by step to create the coolest bra the Empire has ever seen.
See the bra in action in the video after the break.
