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?
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
