The HiViz WorkShop
Assembled Trigger Kits
We'll assemble kits for you on a breadboard and test them with a Vivitar 283 flash unit. The circuits are designed to work with flash units and cameras that require a simple circuit closure for triggering. We provide a cable to connect to your flash unit, but you'll need to splice the cable to your flash unit's PC cord or to a Flash-to-PC adapter. Alternatively, you could connect the trigger directly to your camera with a remote shutter cable. You would need to provide the shutter cable for your camera. You also need to provide the 9-V battery.
We ship assembled circuits in sturdy cardboard boxes that resist crush. If you prefer to have your circuit shipped in a plastic project box, you can add one to your order here. Bear in mind that components can be dislodged in transit and in use. That's the nature of a breadboarded circuit. We will be happy to correspond with you about fixing tech problems that may arise in the initial use of the circuit.

We've added this product based on a number of requests for a circuit that includes a sound trigger, photogate, and delay unit. You'll receive those three triggers 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 individual 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 universal trigger.

All of the combination kits use the same delay unit,
shown to the right. There is coarse and fine control
of the delay interval, both immediate and delayed outputs,
and an indicator LED for testing the outputs. |

The SPG1-DU-A and SPG2-DU-A use the same circuit board but different photogate cables. Click on the photos to view the circuit board and the cables. To order an assembled cable without the breadboard circuit, select below.
