This is the Laser Controlled Relay Kit. 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 device from about anywhere in your home or office without you having to move. Just point the Laser at the light-sensitive resistor and the circuit will turn on for an adjustable time period, anywhere from 1 second up to an hour. After the adjustable time period is up, the Relay will turn itself off and wait for the next Laser trigger. 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. This circuit has many uses including easy access for those that are not able to move about so easily. Think of the possiblities: Remote Control from a Laser Pointer. 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. 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.

cdopeyguy asked Is there such thing as an electrical relay that has variable output voltage based on input voltage?
For example, let's say the voltage send throughout the relay is between 0 and 20V, and the voltage used to activate the relay is between 0 and 5V. Is there a type of relay that, when 2V is input, 8V is out put, or when 4V is input, 16V is output? I'm looking to be able to dim lights remotely.
And got the following answer:
What you need is pulse width controlled switching. In AC a simple circuit involving triac can do that job. But in DC it it a bit complicated using oscilators and PWM circuit.
The light activated relay circuit perform very properly with various applications which are specific to energy distribution and protection. The relays come with wide adjustment ranges using a scale that is certainly simple to study either in three or 4 digits as outlined by the model. These light activated relay circuit support in growing the flexibility in the applications, minimize the general power and upkeep expenses. You’ll find relays which are utilised for general purposes which are available in reputable designs with quick replacement choices. And there are actually models which might be applied for industrial applications and heavier duty applications that work on huge loads. These solutions are produced to meet the lifetime industrial manage demands in the applications.
Their newest solutions are the Time counter, Timer Delay, light activated relay circuit, Speedy Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and different other people. The site provides a detailed description of every model in a variety of categories of light activated relay circuit couplings and sensors. These goods are incredibly beneficial for high-risk applications. The light activated relay circuit are also available with characteristics like multiple timing ranges and functions. The organization is at present seeking agents and dealers who can promote and sell their factory created merchandise. They are usually on a lookout for building new and much more reputable products determined by the requirements and requirements on the sector.
