[lug] Guitar to USB

[Bear Giles]

Size doesn't matter.

There have been some really nasty hacks from people embedding
micro-controllers into cables that are indistinguishable from standard USB
cables. Never trust any cable you didn't bring yourself, never trust any
charger you didn't bring yourself, and *never* connect to a public USB
port. The only exception is if you have a special "power only" cable... and
some knowledgeable people would probably refuse to do that either.

On the bright side there's a guy who's business card is a working Linux
computer. It doesn't do much - but it is a Linux system that you can power
and access via the USB micro port and which fits into a business card
dimensions. (Thicker, since it's surface mount components, but the same
height and width).

It's not a business card you'll drop into the bowl for a free taco but IIRC
the marginal cost is around $3, iirc. Of course the design and build would
be worth many thousands of dollars if he was doing it for someone else.
