These Are The 100 Finalists In The Hackaday Prize

Posted on by

The Hackaday Prize is the greatest hardware competition on the planet. It’s the Academy Awards of Open Hardware, and over the last few years we’ve been doing it, we’ve seen literally tens of projects that have gone from an idea to a prototype to a finished project to a saleable product. It’s the greatest success story the Open Hardware community has.

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 …read more

Video Quick Bit: Power Harvesting Hacks

Posted on by

Majenta Strongheart is back again, this time taking a look at some of the coolest power harvesting projects in this year’s Hackaday Prize.

The entire idea of the Power Harvesting Challenge is to get usable power from something, be it solar energy, a rushing waterfall, or fueling steam turbines with hamsters. [Cole B] decided that instead of capturing energy from one of these power sources, he’d do it all. He created Power Generation Modules, or Lego bricks for harvesting power. There’s a hand crank module, a water turbine module, and enough modules to do something with all that captured …read more

Harvesting Power From Microwave Popcorn

One of the challenges in this year’s Hackaday Prize is Power Harvesting where we’re asking everybody to create something that harvests energy from something. It could be solar, it could be harvesting energy from a falling weight. If you’d like to give a TED talk, it could be harvesting energy from sound waves. It could be harvesting energy from ambient RF, and where’s the best place to harvest ambient RF? That’s right, next to a microwave.

[Jurist]’s entry for the Power Harvesting Challenge in this year’s Hackaday Prize is a simple device that mounts to the front door of a …read more

This Is Your Last Chance To Design The Greatest In Power Harvesting

Posted on by

This is your last weekend to get your project together for the Power Harvesting Challenge in this year’s Hackaday Prize. We’re looking for projects that harvest energy from the ether, and power electronics from solar, thermal, wind, light, or random electromagnetic fluctuations. Is it going to save the world? Maybe, but it’s a great excuse to build some really cool electronics. If you have an idea in mind, this is your last weekend to enter it in the Power Harvesting Challenge.

The Hackaday community has thrown itself full-force into the Hackaday Prize, and there are hundreds of projects entered in …read more

Power Harvesting Challenge: Scavenge Some Power, Win Prizes

Posted on by

It’s a brand new day as the Power Harvesting Challenge begins. This is the newest part of the 2018 Hackaday Prize and we’re looking for 20 entries who will each receive $1,000 and move onto the finals to compete for the top five spots, scoring cash prizes of $50k, $25k, $15k, $10k, and $5k.

Put simply, Power Harvesting is anything you can do that will pull some of the energy you need from a source other than wall-power or traditional battery tech. The most obvious power harvesting technologies are solar and wind. Ditch the battery in your doorbell for a …read more
