That would be helpful but I'm looking for the whole DIY open source project, the way linuxcnc.org is for CNC for example.

Their cheapest PTZ is U$800 ! Must be a *tiny* market. :) --Winston<-- Thanks, though. I like newegg.

For that kind of cash, one would expect very good resolution and aiming capability. Odd, that. --Winston

That depends on what you consider reasonable. The link I provided has enough detail in the images that you can build a pan & tilt from scratch. You can buy 'servo testers' dirt cheap on Ebay, or use a couple 555 timers to create the PWM control signals. http://www.ebay.com/itm/320669324825 $2.55 each, free shipping. I bought this monitor: http://www.ebay.com/itm/180666114346 And this camera: http://www.ebay.com/itm/300592681299 I bought this to mount it in. I thought what better way to hide a camera, than to disguise it as a fake? ;-) http://www.ebay.com/itm/180775138157 -- You can't have a sense of humor, if you have no sense.
