I know I can get a cheap remote shutter release but as I prefer to make things where I can, I want to make my own. It's a simple thing but I need the schematic. Ideally, once I've made one I can easily then add extra features such as interval, timed release, remote trigger etc etc. Edit: Is it the same remote shutter release for the GH1 as the GF1? If so then I have the schematic, just need to order a 2.5mm 4-pole plug!
