Photo Flash Circuits

12 Volt Strobe Circuit: this circuit uses12V DC instead od mains AC. This is very good idea if you don't want to mess with direct mains voltage connected circuit or you want to run the Strobe from batteries.

Adjustable Strobe Light: 120-Volt mains power source, up to20 Hz flash rate

Disco Style Strobe Light: low power, works on110VAC

Easy Xenon DC to DC Converters

Emergency Strobe Flasher Generates 250V: 08/05/99 EDN-Design Ideas / PDF contains multiple circuits - scroll to find this circuit.

Flash Slave Trigger: Flash slaves are used when you need to supplement1-flash unit with1-or several more. This slave trigger simply triggers those other units. It does this by "seeing" the first flash (using a phototransistor) and triggering the other flashes a few microseconds later. The sensitivity of the circuit is adjustable to compensate for ambient light or dimmer than usual master flashes.

Hacking the Kodak Max Single Flash Camera Into a Self Repeating Strobe: this approach is recommended mainly for home brewing a strobe that is powered by a single1.5 volt battery. If you can use a higher supply voltage, there are better ways to do this.

Mini Pocket Strobe Circuit: works from two1.5-Volt AA batteries, based on modified camera flash unit
