Check out this Game of Life Based clock made with a 16×32 RGB LED matrix, via hackaday:
[Matthews] needed a good present to give to his brother-in-law, who just so happens to be a mathematician and programmer. He wanted something functional but equally geeky at the same time, so he decided to try his hand at making a Game of Life style clock.
He was originally inspired by a Game of Life Clock we shared a few months ago, but with a few improvements. First, he wanted a much bigger playing field, so he found a 16×32 RGB LED matrix. Second, he wanted the time to always be visible so it actually works as a functional clock.
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.
