Transistor photogate, assembled
|The assembled circuit comes with the emitter and detector soldered to a 3-conductor cable which is connected to the breadboard. Click on the photos for larger views.|
We assemble trigger circuits on breadboards and test them with a Vivitar 283 flash unit. You'll need to provide a 9-V battery to power the circuit. The circuits are designed to work with flash units and cameras that require a simple circuit closure for triggering. We provide a 2-conductor cable, but you'll need to splice the cable to a cord from your flash unit or order a pre-assembled cable from us. See flash connection options here. If you want to connect the trigger to your camera, you'll need a Camera Opto-Switch to isolate the camera circuitry from the trigger.
We ship assembled circuits in sturdy cardboard boxes that resist crush. Bear in mind that components can be dislodged in transit and in use. That's the nature of a breadboard circuit. We'll be happy to correspond with you about fixing tech problems that may arise in the initial use of the circuit.
