Good news and bad news… the bad news is, we’ve closed our web store and stopped manufacturing after selling the last of the WheelWatcher WW-11 and WW-12 quadrature wheel encoders.

Many thanks to our customers over the 3 years of direct sales (2014-2016), and the 9 before that of sales through distributors (2004-2013).

The good news is we’ve made the WW-11 and WW-12 open hardware and open source, so the designs are not disappearing forever. We may do the same for the ME-110 and ME-210 Unicoder magnetic encoders, as well as the WC-132 WheelCommander differential drive controller.

Individuals may make some for themselves, and companies may make and sell them to others.
