John Park’s Clockwork Goggles demo @johnedgarpark @adafruit #adafruit

Goggles are a great accessory for dressing up your costume — be it for Halloween or cosplay. There are many styles and genres which can be enhanced by goggles, including cypberpunk, steampunk, dieselpunk, Burning Man, mad science, and clockwork, to name a few.   Using a Gemma M0 running CircuitPython is a great way to drive the pair of 16 NeoPixel rings, particularly because CircuitPython makes it so fast to iterate on color and timing in our program.  

John Park’s Screaming Cauldron demo @adafruit @johnedgarpark #adafruit

This terrifying illuminated bowl will give trick-or-treaters quite a scare when they reach for candy and trip the distance sensor!   An IR distance sensor, Trinket M0, NeoPixel strip, and AudioFX sound board plugged into powered speakers combine to make a booby trapped candy bowl. The CircuitPython program measures the distance of objects in front of the IR sensor, and changes the LED colors to match. Then, when you get too close, it screams bloody murder!!  

John Park’s Chilled Drinkibot [email protected] @johnedgarpark #adafruit

Make a nice, cold beverage using thermoelectric cooling! Peltier cooler + Trinket M0 + CircuitPython = refreshing drinks! This project uses a thermoelectric cooling assembly to turn electricity into coldness!! That chill is transferred to your beverage of choice via thermal conductivity, and then transported safely to your drinking glass with a peristaltic pump.
