It was a 12 volt solid state relay

Awesome video!! What cheap flash units do You recommend for a Canon and also if I buy a standard Sound Activated Electronic Switch PCB, would it work for the sound activated flash with no need for any changes/hacks?

Cheers. (:

@orieloz Look for a flash that can go to the lowest power possible - that's where the highest speeds happen . I'm pretty certain any sound activated switch that responds to noise of any kind will do the job :) .

Wait how do you keep the camera synced with the flash? Does that circuit also trigger the shutter release port on the camera? If so what shutter speed do you need to use?

@GalaticTG

The camera was on a 2 second exposure :)

Nice setup. Though you might want to consider using a MOSFET transistor instead of a relay as it will have a much faster switching time.

[dvdowns]

@GalaticTG I do have a transistor replacing the relay - it switches very fast :)

i lol'd @ the part about not shooting the chickens.

great video, very informative. i'll have to track down one of those sound triggers. I've tried water drop photography and i always ended up shooting about 200 photos to get about 5 good ones since i was trying to time the drops. thanks for the tutorial!

Awesome tip! Really cool pictures!

@dvdowns Thanks, I'll have a look at some flash units. What was the component You added to Your Sound Activated Relay, and what did it do?

Very smart set-up. Just don't shoot the chickens!
