From the Forums: Building the Pixel Box – a light-up NeoPixel coaster
Light up your drink in style! From the Adafruit Forums, user kazzle101 documents their build of a NeoPixel ring lighted drink coaster:
This all started with wanting to modify a cheap camping light replacing the LED’s with NeoPixels. So I made a PCB disc to match the existing board that held the LED’s, as well as a board for an ATtiny85 microcontroller, plus a microphone and vibrating motor. The battery and charging circuit came from a cheap (Poundland) USB powerbank. It turned out that the battery from the powerbank didn’t fit in the camping light, so what to do instead?
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
