Build Your Own Camera Flash with a Built-In Optical Slave

If you’re an electronics tinker and photographer, here’s a DIY project right up your alley: a DIY flash bulb with built in optical slave.

At DIY Photography they share a straight forward guide to building your own camera flash, including parts lists and schematics. The build itself is a pretty easy one if you have a few electronics projects under your belt. The only caution we’d throw out is that, because you’re working with flash bulbs, you’re also working with high voltage capacitors. This project includes a 450v capacitor which, under the really unfortunate circumstances, can accidentally discharge into your body and give you a heart attack–such is the nature of working with high-voltage electronics.
