Here Are The Ten Finalists For The Hackaday Prize Wildcard Challenge

November 3, 2021 by Tom Nardi No comments

Each phase of the 2021 Hackaday Prize challenged designers to reimagine traditional solutions within various fields, from robotics to assistive devices. But for the Reactivate Wildcard, the fifth and final Challenge of this year’s Prize, this theme of Rethink, Refresh, Rebuild could be applied on anything the entrant wanted. Today we’re pleased to announce the ten Wildcard projects that have been selected to win $500 and move onto the finals. Who will win the top spot this year? We’ll find out during Hackaday Remoticon in just a few weeks!

The MetaSense project is a perfect example of how new technology can be used to rethink what we generally consider to be a solved problem. This project leverages multi-material 3D printing to produce conductive cells which vary their capacitance in response to physical deformation. With some clever geometry, these cells can be chained together to produce single-part devices which can stand in for traditional toggle switches, joysticks, pressure sensors, and even accelerometers.

Speaking of 3D printing, the Direct Granules Extruder project imagines a future were desktop printers are no longer limited to using rolls of manufactured filament. The key is a robust extruder design that can grind up plastic pellets fast enough to feed them directly into the hotend of a conventional 3D printer. This not only means a considerable operational savings, as raw plastic pellets are much cheaper than filament by weight, but would potentially allow for printing with more exotic plastic blends and even recycled materials.

Some of the projects even made us rethink what’s possible for the individual hacker. The WiFiWart utilizes a miniature single-board Linux computer that was designed and built from the ground up by a single person, using only free and open source software. Whether it’s that this penetration testing gadget has packed a full Linux computer and two WiFi adapters into a box the size of a phone charger, or the fact that it’s been done by a dedicated hacker with free tools, you can’t help but come away impressed with this one.

Wild For Wildcard

With nearly 100 projects submitted for the Reactivate Wildcard challenge, this was clearly a theme that resonated with the Hackaday community. As always, it was extremely difficult to narrow this down to the ten finalists below:

Whether or not they made the Finals this year, the complete list of Reactivate Wildcard entries contains an incredible array of fascinating concepts that are well worth browsing through. If any of them particularly catch your eye, why not strike up a conversation with the creator in the comments and see if you can’t help out? There’s always next year.

October 26, 2021 by Mike Szczys 2 Comments

Oh, walnuts! How can we already be at the end of the last round? 2021 has been a time warp and now we are staring down the final day to enter the Reactivate Wildcard challenge of the Hackaday Prize. You must enter by 7 AM Pacific time on Wednesday or it’s too late!

Of course the good news is that the topic is wide-open. Wildcard is for all the things that didn’t fit in the first four entry challenges. If it’s a good idea, if it’s a build that really matters, it should be entered!

The ten winning projects from this round will each get $500 cash prizes, and be shuttled on to the final round. All 50 finalists will have until November 7th to hone their offerings, at which point our slate of expert judges will pick the most interesting and impactful for the $25,000 grand prize and four other top prizes.

And how, you ask, will you find out who won? The Hackaday Prize Ceremony will be held online on November 20th during the Hackaday Remoticion. So your assignment today is to warm up that keyboard, mouse, and smartphone camera to get your project entered right away! Step two is to grab your ticket to Remoticon for a weekend of wonderful talks, great people, and an inspiring lineup of hardware builds that made this year’s Hackaday Prize truly shine.

Wondering what kind of stuff makes a great Wildcard entry? Majenta Strongheart has you covered in her latest video roundup below.

It’s Wildcard Time, Your Last Chance To Enter The Hackaday Prize!

September 27, 2021 by Mike Szczys No comments

The final entry round of the Hackaday Prize begins today, and the theme is… anything! While we’ve guided you through work-from-home, robots, displays, and supportive devices, there are countless great ideas that don’t fit in those boxes. So for this round, just show us what you got!

Entering the Reactive Wildcard round is easy. Publish a page about your project over on Hackaday.io and use the left sidebar “Submit-to” menu on that page to add it to the Hackaday prize. The point is to build a better future, and we can’t wait to see what you think that looks like. Need some inspiration? Check out the four challenge update videos below to see what others have been entering so far this year.

What’s at stake here? Ten entries in this round will each receive a cash prize of $500 and move onto the final round. There, they content with finalist from the other four rounds for the $25,000 Grand Prize, and four other top prizes. There is also the geek cred of making the finals, a priceless achievement, even if we do say so ourselves.

Ten Winners Of The Hackaday Prize Supportive Tech Challenge

August 31, 2021 by Mike Szczys 5 Comments

Congratulations to the ten projects that have been selected to receive $500, and continue to the finals of the 2021 Hackaday Prize! Each of these are a different take on the Reimagine Supportive Tech Challenge that sought ways to make great hardware ideas work for more people.

Ebooks have made it possible for everyone to have a library in their pocket, and that has included the visually impaired as text-to-speech can read the printed word. But that’s not a complete replacement for reading for yourself and so the Thenar steps in as an affordable, portable braille ebook reader. It leverages a single braille cell on the edge of the device, and a tank-track-style scroll wheel for user input. Complete with a docking station to inductively charge the battery, it’s a high-end reader for those who need an alternative to epaper.

Okay, pop-quiz; how many of us want to have a future involving solar-powered everything? Most of us now have our hands up, but how many of us can set up a high-efficiency solar charge controller ourselves? If this next finalist (pictured at the top) has its way the answer will be just about everyone. The 2.5 kilowatt solar generator in a rugged brief case is packing a whopping 160 (!) 18650 lithium cells. The charging side of the design handles the maximum power-point tracking (MPPT) while the discharging side protects the user with a circuit breaker and all kinds of regulated outputs like 120 V, 24 V, 12 V, and of course all of the USB-C functionality you’d expect from a system like this.

Ten Finalists, Eight Dozen Entries

We cherry-picked two excellent finalists above, but all ten of these are easily worth their own mention (and many have already been individually featured on these pages). Congrats to the folks who will be headed to the finals in October!

It was a tight field of nearly 100 entries for this round, make sure to take some time to check those out and offer kudos in the comment sections of each project. We’re excited to see what comes of the robotics-oriented challenge currently underway!

Redefine Robots Is The Newest Hackaday Prize Challenge

August 23, 2021 by Mike Szczys 5 Comments

Roboticists and automation enthusiasts, start your engines. This 2021 Hackaday Prize challenge is made just for you! It’s the Redefine Robots challenge and it calls for a softer, more utopian side of what tomorrow’s automated future can be.

The promise of robots has always been one of making our lives better. But so far we still don’t have a robot assistant sitting next to us ready to lend a hand. That’s where you come in! Whether it’s a physical, nuts-and-bots robot or a 1’s and 0’s software bot, create something that people can see and interact with in their day-to-day lives in ways that make sense and make us feel good about where technology is going.

We make fun of the robot that’s been brought into the world to pass the butter, but honestly if that’s something someone needs help with, isn’t a robot a pretty good solution? That’s what [Michael Roybal] thought way back during the 2016 Hackaday Prize when he designed Zizzy the robot to zip around a tabletop, assisting people with limited mobility.

In the same year, [Mike Rigsby] was working on a little bot whose purpose was to wander around interacting with people. A robot companion (dare we say pet?) is one way to keep up interactivity for people spending long periods of time alone. Along the same lines is the EMOJO chatbot already entered in this year’s contest that seeks to deliver a digital companion onscreen.

Assistive robots aren’t the only ones to shine here. Consider some labor savers, like pick-and-place robots that help you build electronics. Does that reinvent robots? Maybe, maybe not, but getting a 3D printer to do your solder for you sure does. Think of how revolutionary robot vacuums were for people who own both hardwood floors and cats. Those bots are around humans all the time and seem normal now. What’s next automation to get this introduction into everyday life?

Ten finalists from this round will win $500 and be shuttled onto the final round judging in October for a chance at the $25,000 Hackaday Prize and four other top prizes. Start your project page on Hackaday.io and use the drop-down in the left sidebar to enter it into the 2021 Hackaday Prize.

New Contest: Halloween Hackfest

August 10, 2021 by Mike Szczys 4 Comments

It’s as if Halloween was made for hardware hackers. The world is begging us to build something cleaver as we decorate our houses and ourselves for the big day. And one thing’s for sure: the Hackaday crowd never disappoints. This year we’re fully embracing that with the Halloween Hackfest, our newest contest beginning today along with the help of our sponsors Digi-Key and Adafruit.

The animated video combined with the 3D-printed prop makes for an excellent effect.

Wait, isn’t it the beginning of August? Why are we talking about Halloween? The procrastinator’s dillema, that’s why! Start working on your build now and it will be epic by the time the day actually rolls around. Decorating for trick-or-treaters is a good place to start. For our money, projected heads are a really cool party trick, like these singing Jack-o-laterns, or these disembodied heads inspired by Disney’s Haunted Mansion. Or maybe you’re more of a flamethrower-hidden-in-pumpkin type of person?

It doesn’t take much tech to bring a good costume to life — a few LED strips make a plain old princess dress light up the night and builds some permanent memories for the lucky little one who’s wearing it. Speaking of memories, we doubt the little one will remember this mechwarrior family costume, which is why you’ve always got to make a video of these things.

Over the year’s we’ve seen claw machines for candy delivery, and even a pumpkin piano. Of course pumpkin carving is an entire category unto itself where five-axis CNC machines are fair game. Look around, get inspired, and build something!

Three top winners will receive $150 shopping sprees in Digi-Key’s parts warehouse. If your build happens to use an Adafruit board, your prize will be doubled. We’ll also be awarding some $50 Tindie gift cards to the most artistic projects.

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 Halloween Hackfest. You have from now until October 11th to spill the ~~beans~~ pumpkin seeds on what you’ve made.

Ten Projects Won The Refresh Work-From-Home-Life Round Of The Hackaday Prize

July 27, 2021 by Kristina Panos 3 Comments

Here we are, a year and change into this pandemic, and if you were new to working-from-home every day at the start, surely it has lost its luster by now. We asked you to stand back and assess what can be better about WFH life and you took it from there, building incredibly useful things we couldn’t have dreamed of. From a pool of more than one hundred entries, the judges have selected ten projects whose creators have each been awarded a $500 prize, and will advance to the final round of the 2021 Hackaday Prize in October.

Are your prototypes a mess of wires? Or do you spend way too much time making sure each jumper is cut to the perfect length? Either way, you’re better off using breadWare, which takes a standard breadboard and changes the connection process into a software solution. That’s right — any rail including the power rails can connect to any other thanks to a handful of analog CMOS switch chips.

Maybe you’d love to build the perfect keyboard to grace your battlestation, but are afraid of all that hand wiring. Make it easier on yourself by soldering each key switch to its own little PCB.

If your home office is sometimes overrun by little humans that need immediate attention, you’ll no doubt appreciate the value of a device that can deactivate your web camera and mic automatically when it no longer senses your presence.

You may have left that awful office lighting behind, but you’re still getting plenty of prolonged exposure to blue light. This project aims to head that off a bit by replicating the current outdoor light temperature with indoor lighting. And don’t forget — air quality is just as important, so crack open a window once in a while and build yourself a smart lamp that can give you hard numbers.

This was the second of five challenges in the 2021 Hackaday Prize, which means that the ten finalists linked below will have until the end of October to flesh out and polish their projects before the final round of judging. Meanwhile, we’ve kicked off the next round with the Re-imagine Supportive Tech challenge. Show us how you would make electronics and devices more accessible, as in more modular, hackable, or affordable.
