April Fools has left me thinking of malicious uses of micro controllers that support HID. The thought occurred to me that one could use such a micro controller to do mean things to a co workers computer since they probably wouldn't notice a small device plugged into the back of their machine, especially if disguised as a different normal peripheral device. It would be even more fun I the user could send it commands, preset or otherwise, over bluetooth or wifi or even via ir with a remote control to add to their frustration. The possibilities are endless!
