Remote flash trigger


Posted on May 4, 2012

Transistor Ql is a light-activated silicon-controlled rectifier (LASCR). The gate is tripped by light entering a small iens built into the top cap. To operate, provide a 6-in. length of stiff wire for the anode andcathodeconnections and terminate the wires in a polarized power plug that matches the sync terminals on your electronic flashgun (strobelight). Make certain the anode lead connects to the positive sync terminal

When using the device, bend the connecting wires so the LASCR lens faces the main flash. This will fire the remote unit.
