||Make a 2-d plotter that controls an etcher-sketch from the net so people can write little messages on it.
Edit: Not only that, but can also be used to draw a bitmap image.
Materials required: An etch-a-scetch, two motors, either steppers with adaquate torque, or servos, controlling hardware. Software wise will need a lampmaster interface for the motors plus an application interface for anything more complex, such as a bitmap conversion. Also need a way to shake it. A few solinoids could do the trick.

it would be pretty hard to control with a servo, you would only get 180 degrees.

Servos can be fixed to allow continuous movement.

Why not a normal motor then?

precision control. I don't have an easy way to know how far a regular motor turns, but both steppers and servos can be predicted, although both can slip if the torque isn't high enough. Not really necessary if the control is all manual, but if we want it to draw a bitmap, it'd need to have some kind of idea where it's supposed to be.

have a look at this

you could use ordinary motors but you would have to have a magnet and sensor small enough to mount to the shaft. commonly known as encoders in the industry. not really sure if theyre called something else in their primitive state.

As far as shaking it to erase... perhaps have the etch a sketch mounted with a spring at each corner. Then some type of mechanism to kind of cock/load the etch a sketch (have springs stretched). Have user draw, then a release and the etch a sketch bounces on springs, then gets drawn back into cocked position.

Hey. Etch-A-sketches were made solely to teach boys/men the proper way to tweek nipples. Let's not mess a good think up now! ok?

Egad, do I feel really old now. Before Etch-a-Sketch, there was a psorurcer toy (and I forget what it was called) that was a piece of transparent waxed paper attached to a black-covered cardboard backing. You drew on the waxed paper with a wooden stylus, and your lines stuck to the black background. Once you were done, you could simply lift the paper, and poof, the drawing was gone and you could do it all over again (at least until the waxed paper wore out). I also remember when all jack-o-lanterns were made out of painted papier mache instead of plastic.

That's a smart answer to a difficult qeustoin.
