The final twenty projects for the five categories in the Hackaday Prize have been announced, for Open Hardware, Robotics, Power Harvesting, Interfacing and Music.  Those topics cover a gamut of projects, from building your own motion tracking system through running electronics off of the energy leaked from your microwave to setting up a semiconductor lab in your garage.  As these designs are all open source and part of the competition was to create detailed build instructions you can look through all the submissions for ideas of your own, or a useful project to build for yourself.

"Over the last eight months, we’ve been deep in the weeds with this year’s Hackaday Prize. It’s five challenges, with twenty winners per challenge. That’s one hundred projects that will make it to the semifinals in the hopes of becoming the greatest project this year."
