Things I've Built

Animated Electronic Eye

An Eye on a Adafruit TFT display and Teensy 3.2 that I put into a cameo broach. It has a Li-poly battery and charges via the USB. It's a great Halloween accessory.

LED Goggles

Steampunk goggles that use the Neopixel LED Rings and Trinket from Adafruit. I also have a minor infinity effect built in. Proudly, you can actually wear them and see, but not so well. I also made several cheapo, Borg-looking versions.
