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
