Welcome to the photo flash-section of Johan Brouwer

"low voltage trigger" circuit

The following circuit is from Mark A. Pals and allows connection of a high-voltage flash to a modern camera with an electronic, low voltage, flash output.

Alternatively, the circuit can also trigger a high-voltage flash, initiated by a primary flash.

A suggested print lay-out (thanks to Sander van Leeuwen) can be found below:

PLEASE NOTE: the copper strip needs to be cut out at point 3C and 7D !
