A Learning Remote Control AC Power Switch
Posted: Thu Feb 19, 2009 9:12 pm
If you're not already familiar with a web site called http://www.dealextreme.com, you're in for a few hours of fun browsing through thousands of Chinese made gadgets of indescribable variety at unbelievably low prices. Example: a Bluetooth adapter that is literally smaller than your thumbnail for $2.65 -- and that includes a CD with software and FREE SHIPPING! Check it out at http://www.dealextreme.com/details.dx/sku.11866. Even if a lot of what they sell is junk, the low prices tempt you to satisfy your curiosity without spending much money. One nice thing, everything is priced with shipping included, which makes it easy to shop their excellent web site. On the negative side, be prepared to wait three or four weeks for your order to arrive.
I stumbled across a gadget in their store that is related to what we do, and I thought it was such a fantastic bargain at $5.68 shipped (three for $5.08 each), I wanted to share it with you guys. It's a plug-in AC power switch that can be controlled by most universal infrared remote controls. It's small, just 1-5/8" x 2-5/8" x 1", and has a 2-prong plug on the back and three receptacles on the front and sides. After plugging it into a wall outlet and connecting whatever you want to switch ON and OFF, such as an amplifier, lamp, TV, fan, etc., up to 500 watts, you press a button on the front to put it in "learn" mode. Then fire whatever remote control signal you want it to learn, and thereafter that signal toggles a miniature relay inside the unit that switches power to the receptacles ON and OFF. It even stores the learned signal in an EEPROM so it doesn't have to be reprogrammed after power interruption.
You can buy it here and you can read the technical evaluation of it I posted here under the name "Okasional".
I have three of these things. Other than the one I used for controlling a hard-to-reach table lamp, I don't know what to do with them. I just know they work great, and for the price I can afford to hold onto them until a need presents itself. So let's make this a sort of challenge to see who can come up with the most innovative use for this remarkable gadget.
