Hmmm, that's excellent info. I don't actually have an Arduino, but if IR signals are really that standard, I'll bet there's an even easier and/or cheaper way...

Searching ebay, I found something for $1 that plugs into my smartphone's headphone jack and transmits IR signals. Figuring out the engrish app (Zazaremote) might be a challenge, though. They don't have Nerf or Hasbro in their existing database of device manufacturers.

Yet. =)
