Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I would think you could do exactly that, and that sort of bread and butter project is what the Maximite is designed to handle.

That is possible, but you should synchonise the switching to the start of each frame or you'll get some unpleasant rolling effects.

National used to make an 8-pin frame detect chip, I used one in a laser range detection system I built back in the 90s.
