We received these beautiful display segments at the 29th Chaos Communication Congress in Hamburg from the guys at muCCC (http://muc.ccc.de). They didn’t provide any information about how to do anything with them, so we had to do just a little reverse engineering. After figuring out the whole circuit-board layout to get an idea of what the developers intended for the interface, we verified our results using an ATmega32 on an AVR NET-IO.
Technically we’re able to drive the displays at roughly 10 FPS, which generates a considerable amount of current drewn by the e-magnets flipping the pixel-segments. To satisfy that demand we used the largest capacitor we could find around the hackerspace.
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.
