Sound Triggered Flash Captures Split-Second Action

If you’re trying to capture a event that includes a distinct sound–like a balloon popping or a match flaring up–this DIY sound-triggered flash can help.

This DIY build uses a hacked up disposable camera, a simple 555 timer chip, and home made PCB. It’s not a simple build and probably not the first thing you’d want to cut your teeth on if you’re getting into electronics tinkering, but the design itself is simple and elegant. Hit up the link below for additional information, the design files for the PCB, and circuit schematics.
