Sometimes we miss that old Etch a Sketch we had when we were kids. The challenge of producing a decent image using those two knobs was always fun and frustrating at the same time. This project lets us recreate this interface on our computer. The Hack a Sketch is a combination of an Etch a Sketch style input and a processing sketch to recreate the experience. They’re using an Arduino to interpret the inputs and feed it to the computer via USB. We really like this thing. Simplify the electronics and we could see this as a neat toy for sale somewhere like Thinkgeek.

An exhibition just wrapping up at the Russian Frost Farmers Gallery in New Zealand presented an interactive artwork hack. Called the Radio Assisted Drawing Device (R.A.D.D), it is a plotter that mounts on the wall. It isn’t computer controlled, but rather relies on a remote control with two sticks to move the plotter Etch-a-Sketch style.
A clear gantry mounts vertically and travels along the top edge of the wooden backing. A slot cut in the acrylic steadies the plotter and allows for smooth vertical movement. Obviously built by hand, the mechanics seem to have tight tolerances for precise movements of the stylus. See the exhibit in the video after the break.
Wouldn’t you love to have one of these on the wall at your next party? It adds a whole new spin on a guest book.

[Jeri] put together an absolutely massive Etch A Sketch for The FatMan and Circuit Girl show. She had removed the DLP chip from an HD rear projection TV and decided to repurpose the 52inch screen. The movement mechanism uses pulleys from screen doors with nylon lines. The two sets of lines are fed in a criss cross pattern so that the parallel lines move in the same direction. The lines move tent poles in the x and y which controls the movements of the golf tee stylus. It’s driven by two high torque motors from $9 Harbor Freight 18V drills. They tried several different powders, but ended up using aluminum powder from an original Etch A Sketch because it sticks to everything. It will eventually be hooked up for IRC bot control once they get a large enough h-bridge.
We love all of the creative Halloween costumes that have started trickling in now that the holiday is finally over, and people have found time to document their last minute projects. Take this functional Etch A Sketch costume made by [mazinbenny]. The knobs are lawnmower wheels. The pulley system is strung with 1/16″ wire rope to move a carrier for a dry erase marker. The marker draws directly on an acrylic screen. HowStuffWorks has a post on how a real aluminum powder based Etch A Sketch works.
We’ve covered more technical Etch A Sketch projects in the past. We’ve seen them hooked up to computer mice, drawing portraits at Maker Faire, and commenters have even suggested turning mechanical dry erase boards into giant Etch A Sketches.
