VU Meter Guitar Strap Project

Our latest electronics project is our first wearable electronics project. The Boy plays bass in a band, and I wanted to make him something cool to wear on stage when they perform. Looking around the web for project ideas, I came across the LED Ampli Tie on the Adafruit Learning System, which is a fantastic resource for all sorts of technology information. The Boy isn’t a tie-wearer, though, so I thought I would adapt it to a strap for his bass. It’s going to require a few small changes, but should be pretty straightforward.

The project is based around Adafruit’s Flora micro controller, which is an Arduino-compatible board designed for use in wearable electronics projects. It takes the input of a small microphone and flashes a series of NeoPixels like a VU meter.

Though the plans call for using conductive thread, the hard nylon material the strap is made out of made it very difficult to tie tight knots in the conductive thread, and I ended up with a semi-working model. So, instead, I used flexible silicone coated hookup wire to make it. Of course, that meant about a bajillion soldered connections, but I eventually got it done.

Here’s the final product:
