You've got the ideas, all you need is some power! Share your projects involving power supplies in the Power Supply Contest to win prizes provided by Digi-Key Electronics. Your project can be portable or stationary, so long as a power supply is incorporated in the build. 

Prizes for this challenge include a Microsoft Surface Pro 4, DJI Phantom 3, Amazon Echo, and more. Scratch-built power supplies, as well as projects that use a power supply of some kind, are eligible, and there a special judges' prize for the best benchtop power supply.
