Cheap, multifunctional arduino boards work brilliantly for DIY projects. Now this cheaper, semi-printable version makes the platform even more DIY.
PAPERduino is essentially a template for an Arduino board that, when mounted to cardboard, replaces your typical PCB. (It’s sort of like a printed circuit board, home edition.) Also, if you’re not interested in Arduino at all but would like some geek cred, the PAPERduino will add a free 10 IQ points when you tape it up beside your desk. [guilherme martins via MAKE]
