Not a hobby level project, but the good news is you can buy one cheap. Far less than what you could build one for! Isn't that wonderful news

Yeah, you can buy a 1G for 5 bucks. No joke.

As long as the Pen is the legal age, sure I see no reason you cannot make it drive. But what car what car...

I suppose for a very first time you could do something with the flash modules that Atmel sells over at http://atmel.com/dyn/products/devices.asp?family_id=624 .

Smile very simple...

very simple...

Take the flash out of the pic microcontrollers... collect them .... interface with each other...

Try your best...

ok......but how can i interface ?........and tell me the link where i can collect information abt my project and tell me that can i use 8051 , or ATmega 32 microcontroller???? to make my project ( 1 GB, or 2 GB, ETC..PENDRIVE)

OK....SO...help me some information .....in this feild i m new .......so........first tell me ......that first what's type basics i m read completely that useful abt my project ....ok..

thanks 4 ur rply.......and fast me ur next rply.....frnd....simran.thanks...

The question is why? Is it a school project?

Start by reading the spec sheets from the manufacturer websites. Then search google and find some simple projects. You will have to start with the basics first. A usb interface is not easy. If you try doing that as your first project you will have lots of problems that you would learn to avoid by starting with simpler projects. Take small steps.

Well i am sorry... my this given formula will not work... as flash of pic microcontrollers or any other are inseparable...

I hope you understand...

Better follow this:

take an eeprom ( I2C ) interface it with PIC 18f microcontroller and then interface usb slave with PIC 18f microcontroller...

@OP
if you read in the datasheet for the 18f, it has a special mass storage mode and a dedicated 8 bit bus for transferring data from the host to a sram / nand chip. the 18f cpu handles the handshaking and then a special module inside the 18f handles the actual transfer, eliminating the slow cpu as a bottleneck.

the 44 pin pic and single unit ram chips should only cost 5x what you could buy a real flash drive for

It's a silly idea, use an SD memory card instead - a LOT simpler.

Why would you want to when you can buy one that will be alot smaller than anything you can make by hand?
