CNC Wood Burner Draws Portraits

Check out this raster drawbot that uses a wood burner instead of a pen! The effect is similar to laser-etching wood, but I suppose you could make a rig like this that would fit a much larger piece of wood than will normally fit inside your hackerspace’s laser cutter. I like the stippling effect this Arduino-controlled ditherbot produces, and wonder what other materials could be marked in this way, like maybe leather. Code is on Github. via Hackaday


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.
