There are drawbots, and then there are drawbots. Tim Noble created this “semi-automatic” chalkboard drawbot, built around laser-cut plywood, 3-D printed drive gears, MakerBot electronics, and a lovely old oak blackboard frame. I’ll readily admit that this thing fills me with awe and terror at the same time. I’m not sure why. The idea of an automatic blackboard seems kind of ancient and sinister, and this one is exceedingly well done.
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.
