Disposable camera, h11d2 - Electronic Circuits Projects Diagrams Free

joshua17ss2 · 6th April 2008, 05:30 PM

I am working on a project to simulate lighting for a prop i am making, and i want to use a bunch of old disposable camera flashes, i have read that the charge that is sent thought the trigger is around 400 volts, i have the h11d2 chips and im wondering if this would be a suitable tiger so i can hook all the flashes up to a microcontoller.

does any one know if this would work, or is this is even the voltage that would jump acrossed the trigger pins

thanks josh
any help or ideas are appreciated.

The CAP voltage on most of those diposable cameras are from 200V - 300V, but then there is a tiny step-up transformer that raises the voltage even higher, maybe over 1000V.

As far as using microcontrollers I can't help you there...

The circuits of these cameras are fairly similar, here is the Kodak one: http://www.geocities.com/lemagicien_.../maxflash.html
Several of these could be connected to one switch just by using isolation diodes.
