CHDK (Canon Hack Development Kit) is a software dev kit which enables some Canon cameras to do things they weren’t originally designed to do – such as using the USB port as a remote control.
We have decided we’re not going to support CHDK officially, but that doesn’t mean that we think you can’t use the Triggertrap – below are the instructions for getting the Triggertrap to work with CHDK-enabled cameras.
First of all, you need to make sure that CHDK remote controlling works on your camera. Instructions for doing that are available on the CHDK website.
Next, we need to get the Triggertrap to talk to the CHDK’d cameras…
Building the Triggertrap / CHDK interface
Putting together the interface is pretty simple; all you need to do is to add a power source (4.5v). The Triggertrap operates as a switch for the power source. Finally, you wire it all to an USB type A connector, which in turn connects to your camera.
Parts you need:
- 3x AA batteries
- 1x AA battery holder with switch
- 1x 3.5mm mini jack
- 1x USB type A connector
Wire them all together, hook up the 3.5mm mini jack to the Triggertrap, and the USB type B to your camera, like so:
Or, if you’re a slightly more visual kind of person:
