This spacer allows you to use the codewheel sticker on a variety of wheels (from Budget Robotics or other vendors) or any mechanism that attaches to a servo with a servo control horn.
WheelWatcher kits are really well thought out rotation counters. There's many applications for such a critter that doesn't involve wheels or robotics, so here is an attachment to make it easier for you to use a WW-01/WW-02 for your application.
This spacer allows you to use the codewheel sticker on a variety of wheels (from Budget Robotics or other vendors) or any mechanism that attaches to a servo with a servo control horn. Some drilling on your part is required, but the pre-drilled guide holes make it simple.
The spacer is made of laser cut styrene with a self-adhesive backing. It fits perfectly over all common servo control horns on the servo side of the horn. Thirty two guide holes are provided which line up with all of the most usefully located holes on all common servo horns from GWS, Futaba, and Hitec.
