Topic: Homemade USB memory? (Read 1 time) previous topic - next topic


Hi all,

I'm looking to make some sort of USB drive for very cheap. It can be as small as 1000KB, all I want is for it to cost about $2-3 or less. Even the cheapest flash drives I can find are $5, not including shipping. I'd like to make at least 10, no more than 30. I can solder.

Is this possible? Any ideas?



At this point no, it would not be possible.

Arduino does not have a native USB host interface.

There was a lot of discussion over on the obdev forums about creating a USB memory stick using an AVR for handling the USB protocol - in the end it just wasn't practical. The furthest they got was to have the AVR appear as a storage device, but it wasn't readable using the standard Windows file manager - custom software was required.

Hopefully in the future there will be higher powered microcontrollers which will be able to do what you want. It would be a very useful thing for a lot of applications, such as mobile robotics, datalogging etc.

Spend the $5!

Ah yes, I should add that this doesn't actually have any specific tie-in to Arduino. I'm just looking for an all purpose USB drive. I couldn't think of a better place to ask this question. Does that make a difference?


With only 3$ to spend? No, not possible!
