Incessant tinkerer Phillip Torrone has written a how-to for transforming an iPod into a universal remote:
The idea came to Torrone on an airplane as he was falling asleep, he said this morning by IM.
LKahney: the funny thing is, it's enormously complicated
LKahney: i love it
LKahney: it's hours and hours of effort
LKahney: for a device that can be bought for $10 at walgreens
PTorrone: yah, i built it in my head, then needed to find all the elements i needed
PTorrone: sony just released a $700 remote -- this ipod remote thing is up there
PTorrone: but how can you put a price on controlling your stuff with an ipod? hehe
