Gavan Fantom decided that new-fangled electronic LEDs weren’t enough for his office Christmas festivities. So, he came up with this beautiful 8×8 electro-mecahnical display. Each pixel is controlled by a 3D-printed mechanism that is screwed back and forth to change it from “solid” to “empty”. This mechanism is turned by a servo and there are 64 of them, requiring Gavan to use three Pololu Mini Maestro servo controllers. The entire system uses 448 3D-printed parts and 128 nails to hold it all together and the Python code to drive the servos is written in Python. The results, which you can see in the video below are astounding. You can read more and see the code on his blog
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.
