Car Protection and Safety
This remote works as well as a factory keyless remote. So I used it to wire a relay to the car starter power relay. Simply click OFF when leaving your car, and forget about anyone stealing your car, your keys or carjacking. It will not start with this device under the hood disabling your starter. Piece of Mind has never been cheaper.

Simple Modification Makes This RC Even More Versatile
Out of the box, this unit with its 2-button transmitters, works nicely to latch on a 12-Volt load with one button and latch it off with the other button. The 12 Volts for the load comes from the receiver's power supply through the relay contacts. But I needed a single-button, momentary (non-latching) unit where the relay closes only while the transmitter's button is held down, and opens when the button is released, for a garage door opener. This unit will serve with a simple modification. If you open up the receiver by removing two screws, you will find the 18-pin PT2272-L4 controller IC. Pin 12 of this IC latches high whenever the "ON" button of the transmitter is pressed, driving a transistor which drives the relay coil and closes the contacts. The high output remains on pin 12 until the "OFF" button is pressed. However, pin 17, the "VT" or "valid transmission" pin, goes high whenever either button is pressed, and stays high only while that button is pressed, which is perfect for my garage door opener. So I simply moved the base resistor for the driver transistor from pin 12 to pin 17, and now the relay closes when either button is pressed, but only while the button is pressed.

While you are in there, you can also disconnect the 12-V power supply from the relay contact if, like me, you want isolated contacts. You can cut the PC board etch around the common pin, which is located under the upper right hand corner of the relay as you look down on it from the top with the lettering upright. Solder a new wire to this common pin and run it out to your load with the existing white wire.
Another great All Electronics deal!

I took apart a couple of these for a project and put the pictures up here : http://blog.ericmoon.net/2009/12/remote-control-lighting/

So far, range seems excellent, even with the original batteries.

question
will this function at lower voltage? how low can ya go?

"You've Got Mail" indicator
Installed tilt switch on mailbox lid, to give momentary contact closure to "On" line of transmitter Two foot wire antenna soldered to RF transistor collector increases range. Signal is received at center of my house, over 500' away. Decoder latches on, operating a flashing LED & short musical melody. By placing a 1K in decoder supply, one can reset decoder when grounding decoder to ground. Saves wasted trips to mailbox. Love it!
