Hacktor is a modular PCB development platform... oh, and by the way, also a dog. It's still a work in progress, but it will be ready to bark at the moon (and to any other stranger who gets close enough) pretty soon, so stay tuned!
It will feature a proximity sensor in order to detect when you're near it, playing a barking sound with an audio IC and turning its LED eyes on. Well, and its name says it all... it will be ready for your own hacks indeed!
Added design files of prototype.
