Assembled Breadboard Kits

 

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. You'll also need a cable to connect the trigger circuit to a flash unit. The cable isn't provided but can be purchased separately 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.

Multi-Trigger, assembled

You'll receive a sound trigger, photogate, and delay unit wired on a single breadboard. The delay unit includes both coarse and fine controls of the time delay. Two different style photogate sensors are included. One of them is the SPG1 style with variable separation emitter and detector for flexibility in positioning. The other is the SPG2 interrupter that is convenient for drops and splashes. Indicator LEDs show when the photogate and outputs are working. Click on the images below to see larger images of the photogate cables supplied with the Multi-Trigger.
