Hi George, it took me some time to digest the information you gave me, thanks a lot. The websites were most helpful. I have a constraint with $ (money) and being in South Africa the exchange is against me. With this in mind I went down to the local electronics shop and bought some IR diodes and Photo transistors. I intend on making my own IR beams. What I want is a simple system just to trigger the Camera, of course this may grow. I think for the cable I will buy one of those cheep wired remotes and hack that.
