I have a Rebel XTI that I wish to make an Intervalometer for with an 08M. Try as i might I cannot get a solid state relay (that I know works with a 120volt christmas light string and 5Volts as control input) to work. I think it requires a minimum voltage push on the out put lines to turn on. So I tried a 2n2222. Base to out4 and emitter and collector to the two sides of the switch input of the Rebel. It works but i so sensitive that just touching the base with my fingers makes the camera take a shot. I am very weak on analog circuitry and don't know how to make this work or am I going to have to go buy a reed relay. I guess I am asking if anyone has worked with a 5volt controllable switch other than a regular relay and if so is there a link to a schematic.
Thanks
Steve
