Hey Guys, I was kicking around the idea of making a few shutter kits. Since it would only be a very limited number of sets, the circuit board would be less than professional. If I were to have pad2pad print up a dozen boards it would just be way too much in my opinion. So the circuit is just on a little cut down proto-board. The only difference between what you see in the pic and what you'll receive is that the screw terminals will be labelled, somehow.
It's very easy to operate, +5VDC to one side of the screw terminals, and modulation signal to the other side. That's it! I like keeping the voltage low to a GM-20, makes it last longer, less current draw and it's just easier. At 5V on the coil, the end of the flag will be just enough to clear a beam. Nothing to adjust, just simple and straight forward, it's the same circuit that's been running in my projector for over 3 years now. A mount would not be included with the kit since each projector is going to be different, some may mount horizontal and others may mount vertical. So it's just the driver, GM-20 and a flag. All this for $85 plus shipping.
If there's enough interest, I'll make what I have, a very limited amount.
I guess I could also make just the bare circuit boards if anyone needs them for thier existing GM-20's. Maybe if there IS enough interest I can have a pro board printed.
Well, let me know!
Thanks!
