Canon S3 IS - Now with Remote Cable Release Via USB Cable!

One of the people working on CHDK has managed to port the code from an A710
build, where someone found a way to apply 3V to the USB's normal 5V cable pins
to trigger a CHDK script command. Something that they thought nobody would ever
be able to do since Canon started to cripple all their P&S cameras from having a
cable-release option. Part of Canon's "let's find ways to force people to buy
DSLRs" marketing campaign.


See these pages for photos on how to build a super simple USB remote-cable
release: http://ewavr.nm.ru/chdk/remote.htm

It can be fitted into any USB cable plug and attached to the end of any USB
extension cable when needed. One small switch, one little button battery, it
doesn't get simpler than that.

Here's the link for the binaries and source code for the A710 IS version if
needed http://ewavr.nm.ru/chdk/


Here's the page for the new S3 IS version!

Now you are able to remote trigger your S3 IS camera by any device you can think
of. Just apply a small 3volt button battery current to the normal 5volt pins on
the USB cable. The same signal that tells the camera to switch to download mode
has now been rerouted to a CHDK script command. Use any devices you can think
of, IR remote controls, RF remote controls, light-triggers, any simple
electronic switching circuit in existence!

Just run this simple CHDK script, or insert this simple routine in any of your
own more elaborate specialized scripts to detect whenever 3volts are applied to
the USB cable pins. Just plugging your camera into your computer will trigger
your camera to take a photo, as that applies 5V to the pins, a simple way to
test if it's working.
