i am onto a new project. i need to make or buy a sound activated switch. i need NO momentary functionality and the sound would be like a hard/loud clap. having adjustable threshold would also be good (a pot, etc). the relay is very low amps, on the order of 0.5mA(max). its just a trigger for a DSLR camera.
so, anything COTS i can modify, or perhaps a suggested schematic to build? i was initially thinking ATmega micro controller, which can be done, but probably too much for the need.
maybe something like this where the output is connected to the cathode side of a LED in a opto relay or a 1shot IC?
