Remember those plasticy Etch A Sketch toys from childhood? Two knobs allowed you to draw line images on a flat screen. In this video demo, Jeri Ellsworth and George Sanger give a low down on their net enabled version. Replace the grey screen with a rear projection flat screen and the knobs with cheap drill motors from 18V drills. A Golf tee as the stylus and some tent poles hold everything together and complete the gizmo.
The stylus moves on the horizontal and vertical plane and sketches images using aluminum powder. Finally, they also designed a web interface for their USTREAM live chat room and are working at hooking up the device so that people in chat rooms can operate the Etch a Sketch.
The complete equipment list â€“
- A Mitsubishi rear projection TV with the DLP chip removed.
- $9 gear reduction motors hacked from 18V Harbor Freight drills.
- A Golf tee.
- Nylon wires.
- 4 pulleys.
- Tent poles.
- Aluminum tubing & powder.
Take a look at the video above and see how it has been put together. Check out some similar projects:
