Your mission, should you choose to accept it, is to make a PCB that fits into a 1x1 inch square, has a purpose, and is cool.

Seven projects will be awarded a prize:

One first prize winner gets $100 in credit for the Hackaday store and $50 for OSHPark.

Six other projects will get $50 in credit for the Hackaday store and $25 for OSHPark.

Hackaday store prizes are courtesy of Hackaday, OSHPark credit is courtesy of both OSHPark and Hackaday. Huge thanks to them both for this!

You don't have to use OSHPark to get your boards fabbed, but it turns out they have the lowest minimum price for this size of PCBs—for $5, you get three copies of your 2-layer, 1 in² board delivered (almost) anywhere! Check them out!
