while googling, i found that how can we make a handmade hard disk or mp3 player....
its located here
http://anthad.googlepages.com/
the person who has written the notes seem to have not put them up in adequate detail and therefore i need help in making one of the mp3 player out of SCRATCH so if anyone having notes on this, schematic diagrams, how to build- tutorials, you are always welcomed to post them here...im really interested in such kinds of things so even a little help would be appreiated... a more cost effective/better designed circuit etc. is also appreciated
~~~thanks sid
