We like all of the innovative Halloween costumes that have started dripping in now that the holiday is lastly over, as well as people have discovered time to paper their last minute projects. Take this practical Etch A Sketch costume made by [mazinbenny]. The knobs are lawnmower wheels. The pulley system is strung with 1/16″ cable rope to step a provider for a dry erase marker. The marker draws directly on an acrylic screen. HowStuffWorks has a publish on exactly how a genuine aluminum powder based Etch A Sketch works.
We’ve covered a lot more technical Etch A Sketch jobs in the past. We’ve seen them hooked as much as computer mice, drawing portraits at maker Faire, as well as commenters have even suggested turning mechanical dry erase boards into gigantic Etch A Sketches.
