tech question involving a usb key board, a pda, a hard drive, and a power source?

[doopata]

Ok so i want to make a cool little project that goes like this: you take a book hollow it out to put a keyboard,a pda,a hard drive,and a battery in it. you take a pda and modify the memory by adding a hard drive to it, then you attach the keyboard through the pda's usb port and have the battery connected to the whole setup and put it in a book.

Can i do it and how much will it cost and how do i add the extra memory to the pda

I really don't know, however I have seen something similar done with a small toolbok, so I'm guessing yes, you can do it. good luck...sorry i can't help more

>Can i do it

That depends on the hardware you're using and your level of geekiness.

>how much will it cost

Absolutely nothing, assuming that you have everything on hand.

>how do i add the extra memory to the pda

Try using an SD card, if your PDA takes one.
