I bought an extra one while I was there, this is a fully functioning Parallax dev board, a propeller based Dev board..
Has onboard IR functions and 8 blue LED strip.
A defcon lanyard, and parts that are not soldered onto the board yet..
The parts are a vga connector, and 2 ps2 ports to essentially make this Dev board a simple computer.
Will throw in defcon 20 cd if it helps seal the deal. (pics on request)
This is of course a true Defcon 20 badge from this year as well, if you dont know what Defcon is, google it, its in Vegas every year...
While at the conference, go'ers would sync their badges, and the aim was to sync with as many diff badge types as they could.. after doing all types, around 8 or so, the badge would spit out a code and a social rating from the usb port (terminal program)
This one has been sync'd with all types, or I can make it a virgin type (ie: not sync'd with any other badge..) Up to you...
Also willing to solder the extra parts onto the board if you like..
7 BTC to anywhere in the US,
6 BTC to any Canadian..
