hey!
one of my friend (not exactly a friend) made a one device say multimedia device.....
he can listen mp3's, see video, take a picture by 2.2 mgp camera, record video for 30 min.
device is with 1 GB inbuilt memory, he used micro controller in it (i don't no type) , can connect hard disk to it Upton 80 GB.,also connected external battery..
he told me that whole thing is made by him, he buy the components (like microcontroller , camera , display, sound, some extra slots & built such a circuit.)
i think so ......all components are seems to be placed on USB card reader pcb, i am not sure but it looks like this.............(see attachment)
can you tell me how is it so...........?
