rotating monitor methods
DaOld Man:
I like it. Hope you dont mind if I borrow some ideas from you.
What is sketchup? And where, pray tell, do I get it?

Somehow this thread made its way past me in February, so my apologies for being so late to the discussion.
The LED-Wiz could indeed be used to control something like this. I know AtomicFE allows for a user to tweak the LED-Wiz lighting on a per game basis, and others may as well. One would need only to designate a particular output on the LED-Wiz as "Horizontal" and another as "Vertical". Then tweak all of the control lighting definitions as necessary.
It could also be done with a small app that watches for the game title being played in MAME, searches through the game info file for whether it's a vertical or horizontal title, and then turns on the appropriate outputs.
The wiring would probably want to be such that a limit switch at the end of travel in both directions sends a signal to the software to kill the motor. The LED-Wiz+GP would be a good solution as it has both Inputs and Outputs on one board. Of course, a relay circuit with a means of reversing polarity on the DC gear motor would also be necessary.

ooh, that sounds great! and im already a fan of atomic as well. the rotation on mine is set up so that when the monitor reaches its limit, the microswitch cuts out and is set up for the opposite rotation. so signal-wise my particular set up only needs two different + signals. hmmm...

Its a 3D design program that's free, and easy to use. I think its perfect for designing a cab.

The reverse rotation would be very simple. Using two relays rated for the current of the motor, one supplying current in one polarity to the motor, the other supplying current in reverse direction. A end of travel limit (one for each direction) could turn the appropriate relay off. One output is all that would be needed. Output on, turn monitor one way, output off, turn it the other way.
I just need a software app that can tell when a mame game is called to start, and identify the game. A list could be made with each game displaying if it needs the output turned on.
Default for non listed games would be output turned off.
