I have made huge progress on my filmscreen masking controller. The PIC code, complete with independent controls/sensors for the top and bottom masking is done. The system has been working accurately for a few days now, but I still need to be 100% sure it’s perfect, so a little more testing is required before I finalize on the PC design. The current board design allows for 4 presets, 1.78:1, 1.85:1 (which is very close to 1.78:1) and 2.35.1. My screen masking goes up to 2.60, but I have yet to find a movie that sports that aspect.
Next steps are getting final boards made which will enable control via ethernet, RF as well as adding curtain control so the masking control can happen before the curtains open (or vice-versa) or controlled independently. If you are interested in my masking controller feel free to contact me.
Here are a few more photos of the prototype board for your viewing pleasure:

Let me know when they come out with wireless transmission of HDTV OK? I need it for my ancient house.

TV,
hahahah... we'll when I'm all done with the new boards... we can talk. It should be pretty easy to setup yourself.

Thanks for the reply.. again great looking job. I'm a technical person (a 'Code Monkey' as my wife calls me), but I'd have no idea how to do this.. I'd really love for some kind of instructions on what parts were used, settings, all that good stuff.

This is very interesting, both from the control and the roller part. I have a 10' wide screen that I would love to mask, but only have limited space (about 2") on either side of the frame by which to build a masking system. I'm thinking of some kind of roller system, but not sure how to make it work with that kind of space. Do you have something that describes how the system works mechanically?
Cheers!
