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.
This year, our daughter decided to be a "steampunk girl" for Halloween! So, we decided to dress up her prop costume goggles with some LED rings animated with a sort of clockwork ticking pattern.
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.
Follow along with this simple build to make your own stylish clockwork cog goggles!
In addition to the parts listed here, you will also want some foam stick tape to attach the electronics to your goggles, as well as a small drill bit and drill to run the wiring through.
You'll need a soldering iron and solder, as well as some wire cutters and strippers.
