This is the Remote Camera Trigger. This is an interesting and extremely useful device. This is a Relay activated by those little Red Laser Pointers that you can find anywhere for a couple of dollars. The circuit has a sensitivity adjustment so that you can use it outdoors or indoors. It has been designed to work off of the common Laser Pointers found everywhere and will work with Red, Green, Blue, and White Lasers, LEDs, & Lights.

This device can be set up to turn on just about any camera that requires a switch closure. Simply plug the Remote Camera Trigger into your camera with the 2.5mm plug. Then place the Remote Camera Trigger (RCT) in the best position for you. Apply power to the RCT and make the sensitivity and timing adjustments. From there, simply aim your Laser Pointer at the RCT.

The range is up to 50 or more feet, even in daylight. Now, you do not have to be anywhere near the camera to trigger it.

Just point the Laser at the light-sensitive resistor and the circuit will turn on for an adjustable time period, anywhere from 1/2 second up to 10 minutes or longer.

There are two LED indicators on the PCB, one that will turn on anytime the Laser Pointer hits the LDR and one that will come on while the Relay is energized.

The Relay is an 833H series SPDT relay with Form 1C contacts rated for 7 Amps @ 250VAC. It has a 12VDC coil. The Relay contacts are available as .250" quick disconnect Faston connectors. The available contacts are the Common, NO (Normally Open) and NC (Normally Closed). This means that the circuit can either turn a device ON for a set time period or turn a device OFF for a set time period.

The PCB is double-sided, plated thru-holes, 3.00" long x 1.50" wide made of .062" FR-4 epoxy glass with 1-oz copper. It has green Solder Mask (LPI) on both sides with white Silk Screen on the Top side. It includes four mounting holes. The PCB traces for the Relay outputs are extra-wide on Top and Bottom sides for current-carrying capabilities.

This kit does not include the tools you will need to assemble the circuit. You will need tools such as a soldering iron, solder, wire cutters, etc. Because it can be purchased in many places for a dollar or two, this kit does NOT include the Laser Light Pointer that may be used to trigger the Timer.

This kit is also offered as a "Built & Tested" for those that do not want to build the kit themselves.
