Servo DIY – How to Make a Servo Plotter!

For those of you circuit hackers and servo-addicts, you might be happy to learn that there’s a way to make your own servo plotter.

For this project, we wanted to build a lower cost, lower precision XY table for an installation at TeleToyland. The goal is to allow web users to draw shapes in a sand box, so we wanted a simple XY table that is easy to control from a web application. Since we already have the Web to Hobby Servo connection working well for other installations, using a hobby servo was the desired approach. Most homebrew CNC XY tables use motors like steppers and acme screw drives, but we don’t need that much precision, and they are a bit slower than we’d like.
