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.
