Have a look at this cool project that our friends from Gadget Gangster put together. It is called the Web Clicker, it gives you an easy way to control IR devices from any web connected device such as an iPhone. I think I could through a wench into the demo with an IR Jammer though. 🙂
“The Web Clicker is a web server & IR transceiver. You can record any IR command and play it back via an AJAX web interface or just by requesting a URL. It works great from a cell phone and it’s especially handy for home automation projects.
The Web Clicker is a Propeller Platform USB and E-Net Module, and a very basic IR circuit. Web server code is based on PropTCP, by Harrison Pham, and I wrote a custom object (Magic IR) for capturing and playing back IR signals.
I started researching IR control schemes – after a few days of work, I decided it would be better to code my own IR recorder – this way it’s compatible with any TV without having to look through a huge code list. It’s like a learning remote that has greater than 100ns accuracy & unlimited storage capacity.
I’m using a 38kHz IR receiver, which is the most common (95% of devices). If your devices uses another frequency, it’s easy to use a different IR receiver.”
