how to hack a camera to allow remote triggering
step 2 carefully remove back cover (be VERY careful not to touch any circuitry used by the flash or it will ZAP you )
step 3 locate button on circuit board
step 4 use volt meter to determine the voltage polarity across the bottun (positive reading when red it touched to something positive)
step 5 carefully solder leads to both sides of button
(at this point you can put batteries in and touch the lead together and the shudder should click)
step 6 cut hole in case for wire to escape
step 7 carefully reassemble cover and add some hot glue to wire exit to secure
step 8 attach to you favorite microcontroller neg lead to ground pos lead to pin ,to trigger bring pin low

Great post!
BTW, for those who don't want to open their cameras, you can also use a Pentax camera and the Prism remote IR trigger. It plugs into a servo port and uses the IR remote trigger in certain cameras, of which I prefer the Pentaxes.

Or just get a URBI blip device .. http://blip.com.au/item.aspx?itemID=14

There are a lot of other products and options to achieve this on various cameras here.
And then there's always strapping a servo to the shutter button, which is what I do for cameras that aren't compatible with the above remote trigger products.

cool stuff . i just wanted something cheap and easy to use.

Here's a way to do that with a BS2 with out opening the camera and with out a servo. That I found on the parallax web site.

Breaking open the camera is the most fully functional way but makes it more fragile. U get direct control of the shutter button in the least weight. For the cheap Canon's there's CHDK, which can trigger the shutter merely by applying 5V to the USB V++ pin. U can't download by USB of course.

i will probobly end up removing the case and adding more leads to power , ect and remove the flash and add a 3v reg to replace the batts.

Using a servo to activate a camera button is another method mentioned above by Chris. The idea behind this hack is to allow an onboard microcontroller to activate the camera rather than using human input from the ground. This may be done to geo-locate the image using a GPS input also on the microcontroller.

so how woudl the microcontroller know to take a picture of something you want a picture of, say your doing recon or something, then your like oh i want a pic of that, how does the microcontroller know you want a pic of it? are you sayin you hit a button to activate teh cam?
im confused, im not to clear on this micro controller thing.

well you could make it trigger when you get close to a waypoint , you can also use this

cost is $15
also you can use the same method to activate any of the other buttons like say zoom.
