Enter The 2022 Hackaday Prize And Help Save The World

March 29, 2022 by 7 Comments

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.

Announcing: The 2022 Hackaday.io Sci-Fi Contest

March 10, 2022 by 6 Comments

Ladies and Gentlemen, Sentient robots, Travellers from the distant future, or Aliens from the outer rim, it’s time to enter the 2022 Hackaday.io Sci-Fi Contest!

We last ran the Sci-Fi contest in the far, far past — before the Voigt-Kampff machine was detecting replicants on the gritty streets of 2019’s LA. Back then, we had some out-of-this-world entries. It’s time for the sequel.

Thanks to Digi-Key, the contest’s sponsor, your best blaster, your coolest costume, or your most righteous robot could win you one of three $150 shopping sprees in their parts warehouse. Create a Hackaday.io project, enter it in the contest, and you’re set. You might as well do that right now, but the contest closes on April 25th.

Sci-Fi is all about the looks, so if it’s purely decorative, be sure to blind us with science (fiction). If your project actually functions, so much the better! Of course we’d like to know how it works and how you made it, so documentation of the project is the other big scoring category. Whatever it is, it’s got to be sci-fi, and it’s got to have some electronics in it.

If you’re looking for inspiration, you could do a lot worse than to check out [Jerome Kelty]’s Animatronic Stargate Helmet, that not coincidentally took the grand prize last time around. It’s an artistic and engineering masterpiece all rolled into one, and the description of how it’s made is just as extensive. [Jochen Alt]’s “Paul” robot isn’t out of any particular sci-fi franchise that we know, but of rolling on one ball and reciting robot poetry, it absolutely should be.

Honorable Mentions

In addition to the overall prizes, we’ll be recognizing the best projects in the following honorable mention categories:

  • Star Star: Whether you’re “beam me up” or “use the force”, fans of either of the “Star” franchises are eligible for this honorable mention.
  • ExoSuit: This category recognizes sci-fi creations that you can wear. Costumes and armor fit in here.
  • Stolen off the Set: If your blaster looks exactly like Han Solo’s, you’re a winner here.  This is the category for your best prop replica.
  • Living in the Future: If your sci-fi device was purely fantasy when imagined, but now it’s realizable, you’re living in the future. A working tricorder or a functioning robot companion would fit in fine here.
  • The Most Important Device: Has no function, but it certainly looks like it does. Just blinking lights that blink back and forth, yet the government spent millions of dollars on it.

You don’t have to tell us where your project fits in. We’ve got you covered.

Engage!

Get started now by creating a project page on Hackaday.io. In the left sidebar of your project page, use the “Submit Project To” button to enter in the 2022 Sci-Fi Contest.

You have from now until April 25, 2022 to get it finished. Of course, if your time machine actually works, you can finish it whenever. Check out the Hackaday.io contest page for all the fine print.

8-bit counter made from 555s

555 Timer Contest Entry: A Digital Counter With Nothing But 555s

January 6, 2022 by 11 Comments

With a 555 on the BOM, you never know what you’re going to get. With 40 of the versatile timer chips in a build, you might just get something completely unexpected, like this 555-based eight-bit digital counter.

This one comes to us by way of [Astronomermike], who chose to make a digital circuit with nothing but 555s and a largish handful of passives as his entry in the current 555 Timer Contest. The ubiquitous timer chip is not exactly the first chip that comes to mind for digital applications, but it does contain an SR latch, which only requires a little persuasion to become a JK flip flop. His initial design for the flip flop that would form the core of the circuit had a pair of 555s surrounded with a bunch of OR gates and inverters — within the rules of the contest but hardly in its spirit. Luckily, the 555 makes a fine inverter too, and along with some diode-resistor OR gates, the basic counter module was born.

The video below shows the design and build, as well as the trip down the troubleshooting rabbit hole courtesy of a bad breadboard. Each half-nibble stage of the 8-bit counter occupies a full breadboard with ten 555s; the whole 40-chip string actually works and looks pretty cool doing it.

Truth be told, this is exactly the kind of thing we had in mind when dreaming up this year’s 555 contest, so good on [Astronomermike] for thinking outside the box for this one. To see what other uses people have found for the chip that keeps on giving, or to get your entry in before the deadline on January 10, head over to the contest page.

FlowIO Takes Top Honors In The 2021 Hackaday Prize

November 20, 2021 by 8 Comments

FlowIO Platform, a modular pneumatics controller for soft robotics and smart material projects, took home Grand Prize honors at the 2021 Hackaday Prize. Aside from the prestige of coming out on top of hundreds of projects and bragging rights for winning the biggest hardware design challenge on Earth, the prize carries an award of $25,000 and a Supplyframe DesignLab residency to continue project development. Four other top winners were also announced at the Hackaday Remoticon virtual conference on Saturday evening.

In a year full of challenges, this year’s Hackaday Prize laid down yet another gauntlet: to “Rethink, Refresh, and Rebuild.” We asked everyone to take a good hard look at the systems and processes that make the world work — or in some cases, not work — and reimagine them from a fresh perspective. Are there better ways to do things? What would you come up with if you started from a blank piece of paper? How can you support and engage the next generation of engineers, and inspire them to take up the torch? And what would you come up with if you just let your imagination run wild?

And boy, did you deliver! With almost 500 entries, this year’s judges had quite a task in front of them. Each of the five challenges — Refresh Displays, Rethink Work-From-Home Life, Reimagine Supportive Tech, Redefine Robots, and Reactivate Wildcard — had ten finalists, which formed the pool of entries for the overall prize. And here’s what they came up with.

2021 Remoticon Shirt

Last Call For Hackaday Remoticon Shirts

November 8, 2021 by 3 Comments

Hackaday conferences have a long history of excellent T-shirt designs and this year’s Remoticon is no different. If you want one of your own, you need get on that before Friday. The only way to score on is to buy one of the T-Shirt + General Admission tickets by November 11th — it gets you into all of the conference events just like the free ticket, but also scores you a shirt. (Shipping within the US is free, international delivery costs an additional $10.) What you see above is the actual test print, modeled by Aleksandar Bradic who designed this and all of the shirt from past Hackaday conferences.

Of course the most important thing is that you don’t miss Remoticon, and there is a free ticket which will remain available through the end of the conference, but you can help us with the logistics by getting one now.

The full list of speakers and the schedule is now available on the conference website. We’re delighted to have Elecia White, Keith Thorne, and Jeremy Fielding present keynote talks, and 16 additional speakers on a range of hardware-related topics. (This is notable: we originally planned for a single day of talks but were blow away by all the proposals and doubled the speaking slots!)

You can’t quite rub elbows with all your friends from afar, but you can certainly spend time together in the conference Discord, during the Hacker Trivia (form teams if you like!), at the Bring-a-Hack inside Gather Town, and at the afterparty which will include a live set from DJ Jackalope.

Everyone Who Bought a Shirt, Read This!

If you bought a shirt and have already claimed it using the code we emailed to you, thank you, you are all set.

If you already bought a shirt but haven’t claimed it, check your email. You need to respond to the Google form we sent you. If you bought a T-shirt ticket and didn’t get an email from us, let us know. All shirts need to be claimed by November 15th! Gogogo!

If you plan to order your shirt right now, here’s what will happen. Buy your ticket following the link at the top of this article. We will email you a poll question about domestic or international shipping because we have to use two different ordering interfaces for these — logistics are hard. We will then email you a redemption code and link where you can choose your size and shipping address.

We Appreciate The Patience All of You Have Shown

Thank you to everyone for your amazing patience through this process. We wanted to replicate the experience of walking into Supercon and getting a shirt at the check-in table. Shipping logistics made that a bit harder, but everyone involved has been super awesome about it and that feels really good. See you at Remoticon a week from Friday!

Spooky Winners Of The Halloween Hackfest Contest

November 4, 2021 by No comments

It was a tight race, but the results of the Halloween Hackfest contest are in. We asked you to scare up a terrifying build in one of three categories, and as usual, you didn’t disappoint! These three hackers have each won a $150 shopping spree at Digi-Key to fund their future frights.

Best Undead Tech: 3-Axis Skull Mod for a 12-Foot Skeleton

Nelson Bairos

Skelly the 12-ft Home Depot skeleton comes alive with servos.[Nelson] has been in the Halloween-based animatronics business for more than a decade, but always gets beaten to the punch when it comes to doing the really fun stuff like making things move and speak. Once [Nelson] got their hands on a 12-foot skeleton from the big box hardware store, it was time for the gloves to come off and the fun to begin.

The three axes of movement come from a rotation servo, a tilt servo, and a nod servo, all of which are connected to each other and the skeleton with 3D-printed supports. Lucky for us, [Nelson] documented this first build quite nicely and provided the 3D models, should you suddenly get the urge to go see if they have any of these magnificent skeletons left on clearance.

Best Haunted Smart House: Safety Coffin Grave Bell

Glen Atkins

What’s scarier than the undead? How about people who were buried alive, whether accidentally or not. Can you imagine hanging around in a graveyard, innocently doing tombstone rubbings or some ritualistic sacrifice when suddenly you hear someone ringing a bell and/or a terrified, muddled voice screaming for help?

[Glen Atkins]’ Safety Coffin Grave Bell build forgoes the body part, but in the dark, it’s easy to let your imagination run wild. It looks like a bell on a post, but pass too close and the ultrasonic rangefinder detects unsuspecting trick-or-treaters and gives them a scare by frantically ringing the bell with a big servo hidden inside. We hope they brought spare underwear.

Best Crazy Costume: Computer Head

Skye Rutan-bedard

Holloween costume with an old computer screen for the head[Skye] won a lot of people over last year with their computer head costume that featured a lone blinking eye and a voice. What those people didn’t know was that it suffered from three big problems: it had poor ergonomics from a heavy monitor shell, the blinkenlights matrix used to display emotions was underutilized, and using a keyboard proved to be an inconvenient UI for running the voice. This year, [Skye] set out to fix all the problems and make the costume even more awesome and comfortable to wear.

The brain of this computer head costume is a Raspberry Pi 4. As for [Skye]’s actual head, it is safely enclosed inside a hard hat that’s epoxied to the inside of the case. A wide range of emotions dance across the 16×16 RGB LED matrix that looks great behind some mirrored film, and they go great with the new voice method — [Skye] speaks softly into a small microphone, and the Raspi uses Mozilla’s DeepSpeech to repeat whatever they say in a robotic British accent.

Hack-y Halloween

Congratulations to all the winners, and a big thank you to all 45 entrants for your hair-raising hacks. Thank you also to Adafruit and Digi-Key for sponsoring this contest. We hope you had a great Halloween!
