Problem is, the motors are too damn slow, by the time you
get it open the window is over.
Now, a plain TPS switch setup might not be so bad. You need
a couple of relays and some sort of one-shot to get a close-
back-up duration that gets it done, but doesn't keep the motor
lit up all the time.
Thought about drawing this up before but never got around to
If you had good controls you could probably take out the
limiting resistor that many of them put in, and get faster
actuation. But better safe than sorry, unless you have
a spare motor.
