iPhone Infrared Remote

I purchased the HiTechnic infrared sensor, and last night was testing it out. I works great, and was having fun using it to control a shooter bot. Problem was, I needed to control 3 functions (left/right, up/down, and fire), but my Lego remote (8885) only has 2 functions per each of it's 4 channels. I could get around this by simply changing channel on the TX, but obviously this isn't ideal in the heat of battle.

I have an L5 infrared remote http://www.l5remote.com/ for my iPhone, and set up a new remote on it for my shooter bot. It was able to learn the Lego's TX signals no problem (at least on the 2 channels I was using), and I quickly made a screen to control the bots aim, and a dedicated fire button. I think the L5 unit normally sells for around $40, but I found it on sale a few weeks ago for $20. If you have one, or see one on sale, it's a quick and cool way to set up an infrared remote for your Lego's.
