Join us Wednesday, April 17 at noon Pacific time for the 2019 Hackaday Prize Hack Chat!
The 2019 Hackaday Prize was just announced, and this year the theme is designing for manufacturing. The hacker community has come a long, long way in the last few years in terms of the quality of projects we turn out. Things that were unthinkable just a few short years ago are now reduced to practice, and our benches and breadboards are always stuffed with the latest and greatest components and modules, all teaming up to do wondrous things. But what about the next step? Do you have what it takes to turn that mess o’ wires into a product? What skills do you need to add to your repertoire to make sure you can actually capitalize on your prototype — or more importantly, to get your ideas into someone else’s hands where they can actually do some good? That’s what the Hackaday Prize is all about this year, and we want you taking your projects to the next level!
Majenta Strongheart will be hosting the Hack Chat as we discuss:
- The importance of designing for manufacturing;
- What tools we have available to turn prototypes into projects;
- How the Hackaday Prize is set up this year, and why the theme was selected; and
- Why you should participate in the 2019 Hackaday Prize
You are, of course, encouraged to add your own questions to the discussion. You can do that by leaving a comment on the 2019 Hackaday Prize Hack Chat and we’ll put that in the queue for the Hack Chat discussion.
Our Hack Chats are live community events on the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, April 17, at noon, Pacific time. If time zones have got you down, we have a handy time zone converter.
Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io. You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about.
The now-humble PCB was revolutionary when it came along, and the whole ecosystem that evolved around it has been a game changer in electronic design. But the PCB is just so… flat. Planar. Two-dimensional. As useful as it is, it gets a little dull sometimes.
Here’s your chance to break out of Flatland and explore the third dimension of circuit design with our brand new Flexible PCB Contest.
We’ve teamed up with Digi-Key for this contest. Digi-Key’s generous sponsorship means 60 contest winners will receive free fabrication of three copies of their flexible PCB design, manufactured through the expertise of OSH Park. So now you can get your flex on with wearables, sensors, or whatever else you can think of that needs a flexible PCB.

Wind turbines are great when the wind flow is predictable. In urban environments, especially in cities with skyscrapers, wind patterns can be truly chaotic. What you need, then, is a wind turbine that works no matter which way the wind blows. And just such a turbine has won the global first prize James Dyson Award. Check out their video below the break.
The turbine design is really neat. It’s essentially a sphere with vents oriented so that it’s always going to rotate one way (say, clockwise) no matter where the wind hits it. The inventors say they were inspired by NASA’s Tumbleweed project, which started off as a brainstorming session and then went on to roll around Antarctica. We tumbled into this PDF, and this summary report, but would love more info if any of you out there know something about Tumbleweeds.
Back to the turbine, though. How efficient is it? How likely is it to scale? How will a 3D-printed version drive a junk-bin brushless motor on my balcony? The jury is still out. But if a significant portion of the wind comes from otherwise unusable directions, this thing could be a win. Who’s going to be the first to 3D print one?

Hot on the heels of the 2015 Hackaday prize, with its theme of “Build stuff that matters”, comes another opportunity for hackers to make a difference. But you’ve got to think like Mother Nature for the 2016 Biomimicry Global Design Challenge.
The aim of this challenge is to transform the global food system using sustainable approaches that emulate natural process. Entries must address a problem somewhere in the food supply chain, a term that could apply to anything from soil modification to crop optimization to harvest and storage technologies. Indeed, the 2015 winner in the Student category was for a passive refrigeration system to preserve food in undeveloped areas. It’s a clever two-stage system that uses an evaporative cooling loop inspired by the way an elephant’s ears cool the giant beast, and by use of a wind-capturing funnel that mimics how animals as diverse as termites and meerkats cool their nests.
In addition to the Student category, the challenge has an Open category for teams of any composition. Up to 10 teams will be selected from the Open category to proceed to the Accelerator phase, where they’ll receive support for a six to nine month development of their design into a marketable product. The winner will be awarded the $100,000USD Ray of Hope prize, endowed by the Ray C. Anderson Foundation.
We’d love to see someone from the Hackaday community take home the 2016 prize, and there are plenty of 2015 Hackaday Prize entries that may be eligible. The deadline for submissions is 11 May 2016, so get a team together and get to work.
We anticipate a cornucopia of hacks from the top fifty 2014 Hackaday Prize entrants based on the recent awarding of the 50 grab bags of electronics. That’s right, the grand prize was out of this world but there were a lot of other rewards worth shooting for. Instead of making hardware choices without the seminifinalists’ input we went with a shopping spree on Mouser.com.
It’s a great idea if we do say so ourselves. However, it turned out not to be as easy as purchasing fifty-grand in gift cards. Did you know that none of the major parts distributors have gift card systems built into their sites? We’re of two minds on this. We’d love to open a birthday card from grannie and pull out some chits that can be traded for chips. But at the same time, it would be a longshot for your non-hacker relatives to even know what sites are our go-to parts emporiums.
Long story short these prizes are themselves a hack. We had a lot of help from the sales crew over at Mouser who abused their account tracking software in order to make these credits work. All fifty of the Hackaday prize semifinalists now have a cool G to spend and we’ll be watching their Hackaday.io accounts for updates as they inevitably use the upcoming holidays to embark on exciting builds.
A big thanks to Supplyframe Inc. for sponsoring these 50 prizes, as well as all others awarded for the 2014 Hackaday Prize. Get those workbenches cleared off and
sharpen tin your soldering tips because details about the 2015 Hackaday Prize will start to roll out in just a few weeks. Until then, occupy your time trying to win one of the many prizes offered during our Trinket Everyday Carry Contest.
Google and the IEEE are giving away a million dollar prize to an individual or team, that can build the most efficient and compact DC to AC inverter. The goal is to design and build a 2kW inverter with a power density greater than 50W per cubic inch. To put that in perspective, conventional solar string inverters have power densities around 0.5-3W per cubic Inch, and microinverters around 5W per cubic Inch. So in other words, an order of magnitude more efficient than what we have now.
For the challenge, the inverter needs to convert 450VDC, with a 10 ohm series resistor simulating a solar array, to 240VAC @ 60Hz. Testing will consist of powering various resistive, inductive and capacitive loads ranging from 0-2kVA. The inverter is expected to regulate voltage within 5%, and frequency within 0.05%, while keeping the enclosure below 60 degrees C, and conforming to FCC Part 15 B (Unintentional radiators).
If you and/or your team can figure out the most efficient topology, switching frequency, novel use of high power wide bandgap (WBG) semiconductors, physically reduce the size of the input and output filters, and keep the whole thing running cool. Then get registered before the September 30, 2014 deadline. Inverters need to be functional and the results of this test procedure (PDF warning) sent in before July 22, 2015, then 18 finalists will be chosen to bring their inverters in person to a testing facility in the United States by October 21, 2015. The grand prize winner will be announced sometime in January, 2016
