Remote Shutter For Rebels - Would this actually work?

[Miaow]

Was just searching around on the net looking for prices on remote shutters for the Canon EOS and came across this page on how to make one using a hands-free headset for a mobile phone - Looks very interesting (and cheap lol) if it actually works.

Has anyone here actually tried making one of these?

$5 Remote Shutter Trigger for Canon Digital Rebels

I made one for the D200 but I didn't have the luxury of a 2.5mm socket. The D200 has a proprietary 10pin socket.

I'm thinking of trying it out as it seems an intersting way of making one.

I notice it was saying a few other Canons have different sockets also - This seemed to be more for the Rebel Models etc

Why would you risk shorting out the circuit on your camera when these remotes are like 20 bucks? Even Cheaper than that if you don't mind Ebay

Yes thats true - I am a little hesitant for that reason also on actually doing it - hence why I asked on here to see if anyone's actually done something like this

There really isn't any risk of that. It's not like these things are putting out any power. I made my own switch from RadioShack parts, and it works just fine.

Unfortunately it's not so simple for the 30D.

This will not short your camera. It works well, but won't give you the half press feature (which is important).

If the camera's already been focused in and using manual settings the 1/2 press wouldn't be as important would it?

As far as I know, there are 3 contacts: 1, 2 and GND. Connect 1 and GND to get the auto-focus. Connect 2 and GND to get the shutter release.

Why risk shorting the camera? That's the bloody point. You need to short one of the pins to ground

It's called TTL Logic (or CMOS logic depending on the actual parts) but it doesn't matter if you put a short or 5V into the socket, even if you stuff it up you won't ruin the camera. It will just read it as voltage high / voltage low.
