A while back I blogged about possible uses for my old HTC Hero. I had decided to refit it into a standalone media player.
To begin I rooted my old phone and installed the sleeker Cyanogenmod Android OS. Then I plunked down $12 for an 8 gig microSD card. Today I capped it off with a new battery that I bought from eBay for $3.99. I've charged the battery to 52% and had it playing music for an hour straight. It hasn't budged from 52%.
I would declare success but there's one small problem. Apparently my OS has trouble playing long videos. It's minor in my book but there's I'm looking into it.
