First basic stamp project

Hey,
I just got my first basic stamps... first a gripe, I wish the
salesman at parallax would have mentioned those prototyping boards.
I didn't know about them and I would have bought a couple to
save me from soldering... arg!
Anyways, on to the questions, I am building a video sequencer
for some video cameras I have. What I want to do is have it cycle
to each camera every minute or so so that I can have my webcam
software grab a bunch of different views.
I want to hang a 5v coil relay off a pin and drive it. How exactly
do I set this up? I know I need to stick a xistor and a resistor in
there somewhere but all I want is a schematic that shows how to do
it. I've been looking on the web and everything I find is really
general, it never says "buy a 00-0000 xistor, 00-0000 relay and a
00-0000 resistor from radio shack. Wire them up like this."
I know I should be more into the spirit of handing over gobs of cash
to radio shack to try random components but I don't have much fine motor
control left and soldering when your hands shake all the time is hard.
That's why I bought a stamp in the first place... replace bothersome
hardware with tidy software!
TIA,

You can do this without relays and relay drive circuits. Check out the
AD8174 data sheet at http://www.analog.com/ for an example...
