[James] is one of those guys on a quest to control everything with one device. His tool of choice is an Android phone, which can do quite a lot right out of the box. But he was never satisfied with its lack of IR remote control abilities. He fixed that feature-gap by building a Bluetooth to Infrared translator.
The hardware he used for the prototype is quite simple. A cheap serial Bluetooth modem from eBay lets him connect to his phone. An Arduino board listens for data from the modem and converts incoming commands to flashes on an IR LED. Voila, he can control the tube with his phone.
We love the potential of this hack. The Bluetooth module runs from 3.3V, and reading serial data and flashing an LED is extremely simple. You should be able to use a small uC, say an ATtiny13, and a 3.3V regulator to miniaturize the module. We could see this plugging into the USB port on the back of a TV for power, with a wire extension to put the LED into position. The only shortfall is the inability to turn the TV on remotely when drawing power this way.
Remote codes aren’t particularly large to store either. So this would be pretty easy to extend to full control of all IR-compatible home entertainment devices. You just need a tool to discover the remote control codes.

Call me when you’re driving the IR led with the headphone port.

Lets see your project that is similar or better than this…
Oh wait…
I was just answering a question, not letting everyone know that I was smarter than the original poster because I would design it differently.
Ryan, I brought LIRC to Android, and I thought you might my interested: http://www.zokama.com/androlirc. I use the headphone jack output to send IR.
my first thoughts are what about the codes for an ir adapter(nyko) for the ps3 and using the phone as a remote control for blu ray playback and whatever. I would love that!
I was in the process of doing the exact same thing! Nothing irritates me more than sitting down in my lazy chair after a long day to see my wife or kids have left the remote buried somewhere else. Nice job!
It’s refreshing to see a project that uses a sensible Bluetooth device, and not one of those ridiculously overpriced ones off of SparkFun.
This is the same Bluetooth module right?
$6.60

I was wondering the same thing after spending about 3 times as much for a similar module locally.
(Sorry, i have accidentally reported your comment, hope there is no problem).
This stuff got me thinking. I have seen that most digital cameras can detect ir light. Does this mean that one could figure out the IR codes using the camera on the Android itself?
Couple that with a IR module connected directly to the phone USB, and we’re one app away from the ultimate universal remote!
@ryan call me when ur pulsing the camera flash to produce ir and have a nokia java app compiled to run on dirt cheap fones
Dr. Horrible vehicle hacking FTW!
need to control an aerial vehicle using the gravity sensor of the android i.e. i want my android to work as the transmitter (i.e. kind of x bee module)
any1 got an idea
