i tried seaching for this as i know it's been done before but....

what you need is some small stranded wire that has 3 wires in it. stereo wire is ideal
2 momentary switches, say 1blk, 1red
a 2.5mm stereo plug, like that that comes on earphones
hook up your common wire and then hook up a wire to each pole of the plug.
2.5mm stereo plug (like a smaller headphone plug)
on the plug this is how you want to solder the leads on.
Sleeve - Common
Ring - Focus
Tip - Shutter
a little soldering is all you need to do.
i used a DPDT momentary switch. i push it one way and the cam focuses and push it the other way to trip the shutter.

I made a diy remote switch using info from Digicaminfo - homepage has link to article.

Peter Jensen - Canon N3 remote release - sorry about no web address's but I found them

using Google. And a very good page at
www.peeters.com/300d.html with illustrations of the design I based mine on.

I can recommend this one, it works great, and cost £3.00 ($5) to make. One innovation I made was to use a lead from

an old Sony Walkman defunct headphone cable, the plug is 3.5mm, but an adapter for 2.5mm costs less than £1 ($1).

The plus side of this is you use standard phono extension leads, so you can be several metres away if needed.

Hope this is helpful and I would encourage anyone to have a go.

All the best Bob
