I do a lot of tabletop overhead photography featuring both of my hands, so a foot pedal shutter remote is an absolute must-have! Canon remotes are straightforward to DIY, but the remote for the Panasonic/Lumix GH5 (my camera) has a few resistors in it, which makes it a bit more involved.
I looked it up at doc-diy.net, and sure enough, the switch contact is held high at about 41.1 kilohms (41.1K), and the shutter triggers when the switch brings it down to about 2.2K. This isn’t hard to re-create: Resistor values add up when put in series, and my experiments show you can successfully deviate a bit on the resistor values (try what you have that’s close).
This circuit is the ideal, 41.1K configuration (with the addition of a “half press” focus button which I did not include…
