Synchronising flashes on re-used disposable cameras

Hello, all.

I'm trying to track down a circuit for stringing together and then
synchronising the flashes in some re-claimed disposable cameras I picked up
from my local Boots. I don't actually have a flash gun for my old Minolta
X-300, so the idea of stringing a load of small flashes together at a cost
of pretty much zero appeals. Presumably, I'd need a master transistor switch
to switch slave transistors in each camera? I know enough about electronics
to know that this shouldn't be too tough to do, but not enough to actually
design the circuit myself : ) How would I then hook this lot up to my
Minolta?

Any help much appreciated, Jon.

 

Before you expend too much effort, Jessops sell useful little slave
flash units under the Portaflash brand for about 20 pounds. Being mains
powered, they're not that portable, but very handy for indoor use,
especially if combined with spring clamp light sockets.

 

Hello, Willy.

Thanks for the reply.Unfortunately, I didn't make this clear in my original
post, but what I'm after is multiple flashes, and at £20 each, that'll be
beyond my budget. The great thing about the reclaimed cameras is that I can
have as many flashes as I want for next to nothing.

Cheers, Jon.
