you know what would be a good design an Atmega32u4 on a circuit board not much bigger than the processor it'self with a hole in the top left corner to fit on your keyring smiley-grin some kind of plastic any old house would be used to mount it or soldered on later on if required smiley - it would be good to be able to pop the device off your keyring and stick in the back of someone's computer and then have the program do "spooky" things..like move your mouse around and type messages from "beyond the grave" you'd need to be quick though, next time April Fool... move the mouse around say you have $1Million Owing, all you do is stick it in someone's pc at work or a laptop and walk off and wait smiley-grin - since you're able to control the mouse click the keyboard, you could have a lot of fun, you could include discrete components, eg a listening device a pizeo speaker on an analog pin.... or some trickery for system commands, think the Leonardo but on a keyring, you're essentially putting as minimal components with a bit of the board that sticks out and acts as the male USB plug, a little push clip to release it from your keyring, when nobodys looking, place it in.... since it acts as a HID, there's (not that i know of....?!?! and where if so? lol) no way of reading from other USB devices, eg, you can't keylog a user, i'd like to be able to press 2 keys on the keyboard and have the device perform an action?... i really hope i'm wrong because i got a great copy and paste tool using a virtual keyboard, but if i can't activate it via some key press to use the function there's little point really is there...cheap as possible in mass design, with chip, without chip etc, how about some kind of Vote to idea's put forward to actually prototype and sell, i'm not here to make money and if this suggestion turned out popular and you make a little fortune from it , all that i ask is one thing.... Send Me one or 2 smiley Please smiley lol... and if not you, whoever can or is willing? smiley
the chip can emulate a keyboard mouse > have a look at the leonardo examples for controlling mouse/kyb
