Shutter remote for RICOH cameras

[Toby] wanted to have a remote shutter trigger for his RICOH GR III camera. This brand doesn’t have a dedicated port for remote operation but a bit of research allowed him to build his own trigger. The camera’s USB port is used for triggering but not using the USB protocol. Instead, a pulse pattern on the 5V line identifies the half-press, full-press, and release states of the shutter button. From there it was just a matter of wiring up a circuit centering around an Arduino that leaves room for a lot of expansion into realms like¬†photo automation.

    Well at least now it’s got blog cred.

    The next logical step would be to program in an intervalometer.
