Generic MP3 player emulator ( iPod, Zen etc )
ccsnet gave me a good idea about making iPod emulator.
Here is the deal. 1 end is the female dock for mp3 player (let's say iPod for example). Another end is the USB socket A cable which goes to PC. PC runs simple program which emulates responses as they were coming from the real MP3 player (Zen or iPod for ex). All data like song title etc...
On a PC screen you may just show a visual replica of a particular player. And of course emulate all buttons and stuff.
This way you may connect many devices already developed for those MP3 players and use PDA or PC in a car the same way.
I'll do simple proto in a software section to show off.
How about that ?
