Atherton & District Amateur Photographic Society

Just to let you know, I bought one of these triggers about a year ago. It takes a sound input and fires your flash (balloon pop etc), it also has a motion trigger, so can detect a water drop to fire the trigger. It also has a delay so you can fine tune it etc:

I have assembled it (they do an assembled version), but I ended up using the electronics for another project before getting any good shots.

Out of interest Philip, what did you use your trigger electronics for?

I bought a Raspberry Pi (google if unknown) and used the sound trigger and switch to control the GPIO board on there.
