LED Photo Drawing Robot

I built a robot that moves a LED around to recreate a picture :)

    @dwalton76 Very nice. Have you thought about how to improve the dot alignment? I like your "hotdog as a stylus" project quite a bit as well :).

    Thanks guys :) The left to right alignment is fairly accurate but when LED moves down to the next row sometimes I get a gap because the tension in the cable shifts and pushes or pulls the LED a little. That is what caused the gaps in the lines at the bottom of the Starry Night photo. I thought about trying to make my own NXT cables out of cat6 so that they would be more flexible but never got around to it.

    The hotdog as a stylus thing...I never thought getting a stylus touch to register with an ipad would be so difficult. When I told my friends about using the hotdog they convinced me that I had to start a blog so I could document it :)
