DIY Thumb Drive
This is another one of those simple but neat ideas, a USB thumbdrive that you make your self (if you can call it making).
The idea behind it is to reuse all those old SD and MMC cards you have lying around, from forgotten phones, cameras, etc. You simply slip the card into the supplied case (that’s the making DIY part) and hey presto you have your home made USB flash drive.
You can get the full kit (with complex instructions) from Think Geek.
