Wes has the only OT1m prototype in regular service.  It's a larger
OpenTracker board with an IPS5451 high side switch on it.  You can do the
same with any OpenTracker (they all take the same firmware) but you'll need
to supply your own relay, MOSFET, etc.  I haven't made any more of that
particular version because the layout needs some changes and I haven't had
time to work on it.
