Audio flash trigger…
I’ve spent the last couple of days building an audio flash trigger. The idea is that it fires the flash when it hears a loud noise, like a balloon popping or an egg smashing. So far, I’ve spent under £2 on the project. When I’m happy with it I’ll post some more info, build pictures and instructions etc.
It works, but it ’s going to need a little bit of practice to get any decent results. This is the best I’ve managed so far:
The next stages are to:
- Solder up what I’ve got, so I can use my plugboard for something else
- Build a delay box to give better control over when the flash fires
- Either buy a new flash with power controls, or modify my existing flash (Replace the LDR with a variable resistor) – a lower output from the flash should be a shorter burst of light, which will reduce the motion blur I’m getting
- Sort out a black background cloth, and arrange some more interesting lighting!
- Get myself a lense that’s better suited to this than the one I’ve got…
