Beam positioning with GM20's ?
I have a couple of GM20's enroute to me that I hope to incorporate into my projector - I plan on using them for beam shutter and beam positioning control.
Since I don't really need a variable input signal to drive them, I was thinking about using a fixed voltage input with a trimmer potentiometer to adjust the desired deflection / beam position.
Would my idea work, and if so, what is the max input voltage that could be safely used without damaging the GM20? In lieu of my idea, could anyone recommend a simple driver circuit that would provide the same results? I really want to try to avoid "cooking" any components if possible!
Thanks!
