X, Y, RGB Box in ILDA Cable?

[Wondergy]

I'm about to do a lot of school programs, so lots of quick focusing in odd spaces will be happening.

I'd love to put a box in series with the ILDA cable with potentiometers for X, Y, R, G, B so we can set power and image size low to start, and dial it up as needed for the space. Yes, we could do it in software, it's so much better in a physical process.

Plus that way we can talk about color mixing without having to mess with software during a show. We could just "project" a white image, and adjust at the dials.

Would this work? Is someone already making one worth buying inexpensively instead of making one? If not, any recommendations for potentiometers that would keep the signal clean and have a good range?

Thanks so much for your help!

This would actually be a really easy afternoon project, just a lot of wiring. The color channels would just need potentiometers, 10K would work fine. The X/Y signals would likely need ganged potentiometers if your projector uses differential. Something like this would work for X and Y: http://www.ebay.com/itm/10-Cosmos-10...item2c5b1ebf40

So if you are running an RGB projector, you'd just need the 3 pots for color, 2 ganged pots for X and Y, a DB-25Male, a DB-25Female and a little project box from radio shack. All the signals would get wired the same, one side attaches to the incoming signal, the other side attaches to ILDA pin 25 (GND) and the wiper of the pot attaches to ILDA out connector.

I think one of Stanwax's ILDA Gem boards may do some of what you're suggesting. Just plug it into the ILDA port on the back of your projector and adjust the colour pots ;-)

Pretty much a ready made solution.
