Enter The 2022 Hackaday Prize And Help Save The World

The biggest challenge facing humanity over the next century is how to do as much or more, with less environmental impact. Reducing our collective footprint on the planet is of course not any one person’s responsibility alone, and if it’s going to require a million clever solutions to create a sustainable future, then we know just the group of hackers to get to work.

This year’s 2022 Hackaday Prize challenges you to think of big or small ways to create greener energy sources, make recycling easier, hack old devices to save them from the landfill, or build out the networks that keep our local communities together and conscious of our group effort. If you’ve got a super solar harvester, a recycling robot, or even reverse engineering tools to help combat forced technological obsolescence, we want to see your hacks. Or if you’d like, you can simply save the world in the wildcard round.

As always, courtesy of our overlords at Supplyframe and the generous sponsorship of Digikey, we’ve got tons of prize money to give out to the best projects. The top ten projects in each of five challenge rounds will receive a $500 cash prize, and five winning projects will bag from $5,000 to $50,000 in the finals in November. But you shouldn’t wait — the first round, Planet-Friendly Power, starts right now!

Get your team together, start brainstorming an idea, post it up on Hackaday.io to enter in the Prize, and you’re on your way. Independent of the judging, we’ll be looking through the field and writing up awesome projects as we find them. This is your chance to be seen, to help create a better world, and maybe even to win big.

Challenge Date The Details
Planet-Friendly Power Mar 29 – May 1 Your solution should lower the cost of clean energy, through energy harvesting and/or storage efficiency improvements.
Reuse, Recycle, Revamp May 1 – June 12 Your project facilitates recycling of material that would otherwise end up in the waste stream.
Hack it Back June 12th – July 24 Your project adds new capabilities to older electrical gear to keep it useful.
Climate Resilient Communities July 24 – Sept 4 Design devices that help communities be more resilient to weather and climate disasters and/or collect data from their environments so that they may advocate for changes in local infrastructure.
Save the World Wildcard Sept 4 – Oct 16th This is where anything goes, your designs should stand apart from the other challenges but still create a more promising future for all.

A miniature Vectrex console being used

Finally, The Venerable Vectrex Gets A Mini Makeover

It appears that every great console is bound to get a miniature remake: we’ve had the PlayStation Classic, the Mini NES and SNES, and even a miniature Sega Genesis/Mega Drive. But one great console that was sorely missing from that list, at least according to [Brendan], was the Vectrex. So he went ahead and built a fully-functioning miniature Vectrex Console.

If the name “Vectrex” doesn’t ring a bell in your mind, you’re not alone: a commercial failure, it was quickly forgotten by most following the 1983 video game crash. But it has retained a cult status among enthusiasts due to its unique design featuring a monochrome vector monitor, onto which you can place transparent overlays to obtain a sort-of color display. Its games can now all be emulated using software like RetroPie, which is what [Brendan] chose to run on a Raspberry Pi Model 2 that he had lying around.

As for the display, he settled on a Pi-compatible 3.5″ TFT device. Hooking it up to the Pi was easy enough, but getting the image rendered in its proper portrait orientation was quite a headache, requiring endless fiddling with drivers and configuration files.

Once he got this working, [Brendan] set to work designing a miniature copy of the Vectrex’s original case. It took a few iterations and several 10-hour runs on his 3D printer before he ended up with a sturdy case that securely held the Pi and its display in place. A few more hours of printing later he also had a handheld controller, which he based on an Arduino Pro Mega. The Arduino reads out four regular pushbuttons and a joystick, and communicates with the Pi through a coiled USB cable.

The end result, as you can see in the video embedded below, is the cutest little Vectrex we’ve ever seen. It’s really the opposite of this big-screen Vectrex project. We’ve also seen a Vectrex projector, and even one with a real color monitor hacked in. Continue reading “Finally, The Venerable Vectrex Gets A Mini Makeover”

LEGO String Winder Hints At Greater Possibilities

Unless you’re an avid fan of 1997’s box office hit Mouse Hunt, or actively working in the string industry, you probably don’t spend a lot of time thinking about how those balls of string are made. [ord] has, however, and built a tidy little winding machine that has us contemplating the possibilities of how useful LEGO machines can really be. 

The design uses a large and imposing-looking ring gear to drive a spinning arm which carries the string onto the bobbin. The bobbin itself is rotated along with the spinning arm as the hand crank that operates the machine is mechanically linked to both. As the arm and bobbin turn, string is deposited onto the bobbin, building up into a pleasing ball of string that looks just like the ones you buy at the store.

We suspect that, unless [ord] is doing some very interesting things that we haven’t seen yet, the string was probably sourced off a reel or ball anyway, and this machine just serves to demonstrate how the process works.

However, it does go to show how LEGO machines can do real work. We’d love to see LEGO put to more practical uses like winding pickups or transformers, or other jobs that are maddeningly tedious when done by hand. Video after the break.
