A device like this is so amazingly handy to have in your photo bag. With a few of these attached to a few flashes salvaged from disposable cameras you can totally light up whatever your photographing. I think I’ll try that and see what sort of effects I can get with this. I’m thinking four plus point lighting on a sub shoe string budget can be achieved with this.
This is a project to make a Slave Trigger for an electronic strobe unit. The Slave Trigger is plugged into the sync cord (PC Type) from a strobe unit and will flash the strobe when it "sees" another flash go off. An older 1970’s Epoxy cased slave trigger (AC Plug Style) was used as a guide in developing this new version. Thanks to input from some of my web friends we now use a photocell from a $1 solar powered calculator as the photo diode. This Project uses a SCR, Capacitor, Resistor, Photo Cell, an Radio Shack Adaptor Plug, and a small plastic box. The parts were found at a local electronic surplus store and the Dollar Store.
