[Joedefa] had a Griffin Beacon Universal Remote that was collecting dust, and decided that it needed to stop collecting dust. He had a growing number of wireless devices in his house and found himself in need of a remote to control them all. The Griffin Beacon fit the bill, but most of his lights and outlets were RF controlled. So he did what hackers do best… broke out the screw driver and soldering iron and rewired it!
[Joedefa] is using an Attiny85 as the brains between an infrared LED and a RF transmit module (if anyone can identify the source of this module, please let everyone know in the comments). A pair of red and green LEDs lets him know if the remote has received commands successfully.
It’s always nice to see a discontinued product made useful once more with a little ingenuity and an Arduino some hacking skill. Hat’s off to [Joedefa] for a righteous hack!
That RF module is just a simple 433MHz modulator. You can buy the TXRX pairs for like 50¢ on aliexpress
I think this is the RF module: http://www.ebay.com/itm/RF-Radio-Wireless-Data-Transmitter-Receiver-433MHz-NEW/111415494887?_trksid=p2141725.c100338.m3726&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20141212152715%26meid%3Dd28f0df29a004887ae0322e3246d5875%26pid%3D100338%26rk%3D1%26rkt%3D26%26sd%3D230869801124

The radio module (FS1000A) is now called a PCF10 radio module and transmitts at up to 9600 BAUD. They’re available in 315MHz / 418MHz / 433MHz/ 915MHz. The one in this project is 433MHz.

There old tech now and getting hard to find. More or less obsolete.
Just look for “433mhz” on ebay ad sort by price. You can get tx+rx combos for less than 1$: http://www.ebay.it/itm/121131013435
Hey guys! Wow thanks for the featured article I grealty appreciate it. This is the rf module pair I used. http://m.ebay.com/itm/281533665689?nav=SEARCH It was 99 cents. I’m uploading the code for the project on my hackaday.io project page.
Thanks again
