The Countdown to Maker Faire Bay Area is On!


XY servo sandbox drawing tool

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. The Hobby Servo approach also gives us absolute position control, and helps keep the cost down too – using industrial servos would be great, but a lot more expensive. We were also looking for a lower cost way to do the linear glides – trying to avoid costly linear bearings etc.

You can test it out yourself here!

    Glad to see the TeleToyland Sandbox on the Make web site! I’ve been a maker all my life, and love the magazine – definitley found some inspiration there!

    It’s funny since I came to the site to look up a servo hacking article (“One-Ton Linear Servo by Windell H. Oskay), for the Sandbox site! :-)

    Thanks, and have fun!
