ah yes. i think i remember reading that thread too. my circuit doesnt need diodes, but it relies on a double pole single throw switch



now i think about it, my circuit is quite simple as is, but to modify that circuit with transistors would be messy. i guess i can use a change over relay in place of the switch which will only need one signal- on/off.

of course, once i get my cab here, i have to make it work again first...

Yes, I have read your first posts about your circuit. Very simple and should be a good way to go for manual only control.
You could use a relay to do the same, by swapping the switch with a DPDT relay.
I first thought about the notion of using one printer port output to rotate the monitor.
Output on, turn CW, output off, turn CCW.
But this method has some major drawbacks.
First that comes to mind is that if the output turns off for any reason, when it should be on, your monitor will take off.
Windows does crazy things with printer port outputs, and Ive seen different things on different computers.
I agree with Weisshaupts argument about using his or mine software.
You could also very easily use two relays as the drive. You can turn on the relays from the printer port via transistors of opto isolators.
Either of our programs doesnt have to see the limit switches, you can set each to turn off after a certain amount of time. But again, this has a few drawbacks too, but should work.
Anyway, good luck with your project and please keep us informed..
