    How to Build a Wireless Remote Control:

    • Open the remote control housing and place a push button switch on the side. In the upper right corner of the housing, fasten a 3-volt battery holder. Be sure enough room is available to install and remove the battery.
    • Run a wire from the push button switch and link to the 3-volt battery holder at the negative connection. Attach another wire to the push button switch and lead it to the Meg 1/4W resistor and the NPN silicon transistor. Run a third wire from the Meg 1/4W resistor and attach it to the 22K 1/4W resistor and and the PNP silicon transistor.
    • Position the infra-red LED on the front of the housing. Attach the LED and run wires to both transistors. From the 22K 1/4W resistor, run a wire to the C220.01uF 16v ceramic disk capacitor. Run another wire between the NPN silicon transistor and the ceramic disk capacitor.
    • From the positive connector on the 3-volt battery holder, connect a wire to the PNP silicon transistor. This will allow for proper current flow in a closed circuit. Ensure the push button switch is positioned to "off" and place a 3-volt battery into the holder. Close the remote control housing.
    • Point the remote control at a receiver, making sure the LED on the control is aimed at the LED of the receiver. Push the button and the receiver should power on and off. To adjust the receiver to be programmed, point the remote control and hold down the push button switch. Adjust the pot or taper on the receiver until you hear a click. This links the remote control and the receiver.

    Usage of RF Wireless Receiver Module:

    • Car monitoring, RC, telemetering, small scale - wireless network, door access control system etc.

    Package Included:  

    • 1 x Wireless Receiver Board Module

excellent choice
00:00:00 05-23-2011
This thing is awesome. I gotta find more uses for these things as they are so cool. I have the remote hidden under a ledge. People have no idea how the disco lights seem to come on and go off "on their own". A very clever device. Love it!

Not bad
00:00:00 05-02-2011
I use this product for Fluorescent Tube Lights. The only complaint I have is that sometimes on switching on, the light is a little dim at the start (for a couple of seconds at the most). Not a major thing though, I am happy with the product otherwise.

Works well for indoor use
00:00:00 04-13-2011
I purchased this item because I have powered spealers attached to my tv. I don't have a stereo system with it's pwn remote control. I got tired of having to get up and turn the speakers on and off. After reading reviews, I purchased this device. It has worked very well indoors from a a distance of under 15 ft. I like this unit because the box has a short cord and does not crows my power strip. I have not had any issues with interference from other RF devices. The clicker sits on my coffee table next to the tv remote. It's not so small that I lose it. I'm happy with this device for indoor use.

Not easy to switch off
00:00:00 03-29-2011
I added an exhaust fan to one of my bathroom 2 years ago, to avoid the hassle of wiring and installing switch, I bought this. Turning the fan on has never been an issue, turning it off sometime is a challenge. The receiver apparently received the signal, but after a brief pause (or slowdown), the fan just keeps going. <br/> <br/>On average I need to press the button 3~6 times before it finally stops. It may be some kind of interference, or regenerated current, I am not sure but it definitely an annoyance.

Works as advertised

Works great, set up at about 35 feet as a remote switch for cabinet lights. So far, no issues, no interference. Appears to be of decent quality.

It works!
00:00:00 03-02-2011
used the product for controlling a lamp in the same room, works great. Did notice that the product requires a short delay ( 2-3 seconds) to switch on then back off again.
