I just put together my NASA Pod Retro MP3 player over on instructables.
Steam punk is played out, this is straight up NASA punk. Or at least I imagine if it were the 1960s space race and NASA was commissioned to make an MP3 player, this is what it would look like.
This project uses the Daisy Mp3 Player kit from MAKEzine, a VU meter from this instructable , and a case from Curious Inventor.
Check it out if you get a chance.
