GH5 Foot Pedal Shutter Remote

A DIY foot pedal shutter remote is an absolute must-have in my tabletop photography arsenal. The GH5 remote has a few resistors in it, which makes it a bit more involved to DIY than, a Canon shutter remote, for example. I looked it up, and sure enough, the switch contact is held high at about 41.1K ohms, and the shutter triggers when the switch brings it down to about 2.2K ohms. Resistor values add up when put in series, and some experimentation shows you can successfully deviate a bit on the resistor values (try what you have that’s close).
