Other USB Ducky

[Dog9w23]

So, I want to make my own Ducky, but most places that sell the compatible USB's are more expensive than I would like to shell out seeing as I am saving for college. I was thinking about how the first Ducky was made, and it seems to me that it wouldn't be completely impossible to get a SanDisk Cruzer 8gb to act in a similar way. I was wondering if anyone else had thought about this or even attempted it on a flash drive that isn't one of the "supported" ones.
