Electrographic Enlarging Sketchifier does your drawing for you

Back in the 80’s, there used to be a kid’s toy that would allow you to replicate an image by tracing a pre-drawn picture in one panel, while a mechanical arm laid down ink in another. We’d be hard-pressed to remember what the thing was called, but this Electrographic Enlarging Sketchifier would be a wonderful modern day stand-in.
flickr user [Imajilon] constructed this cool motorized pantograph out of tongue depressors, rivets, foam core board, and a handful of electronic components. Despite its bargain basement bill of materials, this thing is pretty darn cool. An optical sensor “views” an image and drives a simple FET circuit, replicating the picture automatically using an electrically driven pen mechanism.
Looking through her flickr stream, we thought the results were quite impressive. She does plan on making a second version of the Sketchifier with a smaller light sensitive area, which should allow her to resolve even smaller features of the source drawing.
