Some folks over at the HDRLabs have come up with a rather cool hack for their DSLR camera and Nintendo DS. Dubbed the Open Camera Controller (OCC), it uses an older Nintendo DS to control the functions of Canon DSLR cameras, though Olympus and Sigma cameras are also supported. The best part is, this device can make connected cameras perform functions that the manufacturers didn’t add in by default on the camera, such as the ability to capture time lapse shots with a built-in alarm and triggering the shutter by clapping your hands instead of pressing the shutter button. If you’re interested in coming up with one of these yourself, instructions on how to do so have been posted by HDRLabs. The OCC was tested with the Canon 30D, 40D, 50D, 5D and 5D Mark II, Sigma DSLRs, the Casio EX-FX1 and the Olympus E-P1.
