OK, so, my wife bought son a tiny etch-a-sketch. I, of course, being me
picked it up and began playing with it. Also, being me, couldn't get the
constantly running thought out of my head: Vector Graphics and servos.
Now, here's the question. Is there available a hobbyist servo drive
system? Communication via TCP/IP a plus, but not necessarily a must I
still have serial ports, and USB is no problem provided it has good
Windows drivers and a usable API. Would be great fun to transfer vector
graphics from some vector format to an Etch-a-Sketch screen. ;) Just
need a way to couple the motors to the knobs, and mount the thing. Bonus
if the assembly is light and stable enough to just flip and shake w/o
having to remove the toy.

Sounds like it would be a good project for the magazine "Make:"
(www.makezine.com)

Some really impressive stuff there. My favourites:
- Photographic grass.
- The "melted" car.
- Modding a GPS to sound like GLaDDOS. (!)
I'm just sitting down to read how to build a CNC machine... >:-D

One project that was recently featured in the print version of the mag might
be of special interest to POVers is:

A 3D prototyping printer which uses melted sugar for the media.

Ah yes - every time I read about this I end up wanting to try it. ;-)

Your wife bought a son?
Your son bought a wife?

Sorry for being grammatically awkward ... "My wife bought my son a tiny
etch-a-sketch." ;) I do that a lot.
Better phrased would be "My wife bought a tiny etch-a-sketch for my son"
I suppose. Perfect grammar isn't my goal, obviously.

I've been thinking of building a RepRap 3D prototyper.
http://www.reprap.org
It's open source hardware, and it can make most of the parts
needed to make another one of itself.
The most current design "Darwin" is based around an Arduino board
with an ATmega processor. http://www.arduino.cc/
The Arduino can use a standard USB for interface and firmware
programming.
Darwin uses stepper motors instead of servos, but there is a
rotary encoder designed for a gearmotor that drives the plastic
extruder.
http://www.reprap.org/bin/view/Main/Magnetic_Rotary_Encoder_1_0
That could be adapted to most DC motors make some sort of
servo. It's also possible to salvage the encoder wheel out of an
old style mouse.
Kai has built an etch-a-sketch plotter...

I think it was shown in povray.org news once...

Googling "usb servo controller" gives some interesting results on the first
page...
