From Ferraris to F-16s, some things just look fast. This Rubik’s Cube solving robot not only looks fast, it is fast: it solved a standard cube in 380 milliseconds. Blink during the video below and you’ll miss it — even on the high-speed we had trouble keeping track of the number of moves this solution took. It looked like about 20.
Beating the previous robot record of 637 milliseconds is just the icing on the cake of a very cool build undertaken by [Ben Katz]. He and his collaborator [Jared] put together a robot with a decidedly industrial look — aluminum extrusion chassis, six pancake servo motors with high-precision optical encoders, and polycarbonate panels for explosion containment which proved handy during development. The motors had to be modified to allow the encoders to be attached to the rear, and custom motor controllers were fabricated. [Jared] came up with a unique board to synchronize the six motors and prevent collisions between faces. Machine vision is provided by just two PlayStation Eye cameras; mounted at opposite corners of the enclosure, each camera can see three faces at a time. They had a little trouble distinguishing the red from the orange, which was solved with a Sharpie.
[Ben] and [Jared] think they can shave a few milliseconds here and there with tweaks, but even as it is, this is a great lesson in optimization and integration. We’ve covered Rubik’s robots before, like this two-motor slow and steady design and this six-motor build that solves a cube in less than a second.
Today the 2018 Hackaday Prize begins with a roar. This is our global engineering initiative with huge prizes for those hackers, designers, and engineers who want to use their skill and energy to build something that matters. This year, we challenge you to Build Hope. Show the world the amazing ways technology enriches humanity, and that its benefits can be shared by all.
There is over $200,000 in cash prizes headed to the most interesting hardware builds of the year. With plenty of room for great ideas, the top 100 entries will each receive a $1,000 cash prize and continue the build to final judging. The top five entries will be awarded a $50,000 Grand Prize, and $20,000, $15,000, $10,000, and $5,000 for 2nd through 5th places. We even have some additional seed funding set aside to help early entries to get started.
What is Building Hope?
It feels like there is a steady drumbeat of doom and gloom surrounding technology these days. We hear this foretold in many ways, things like robots rising up to enslave humanity, artificial intelligence and big data being used to manipulate people, and quantum computing on the horizon that will invalidate cryptographic security. Our challenge? Get in there and show the incredible good that technology can do in the world.
Design something that shows the benefits of using knowledge and creativity to solve a problem. Be the shining light that proves our future is full of hope because smart people care about what happens in the world and to the people who live here. It is our responsibility as those who understand powerful technologies to show the best ways they can be used to build up humanity. This is your chance.

Five Years of Amazing Engineering
Thousands of entries have been submitted to the Hackaday Prize over the years. Founded in 2014 by Supplyframe CEO Steve Flagg, the Hackaday Prize is now in its fifth year. The challenges change each year, but the goal remains the same: to Build Something That Matters. We are consistently amazed both by the quality of the solutions, and the uncovering of new and interesting problems targeted by the entries.
Studying earth’s oceans is increasingly important be it due to climate change or pollution. Alex Williams was awarded the 2017 Hackaday Prize for his Open Source Underwater Glider, a suite of sensors built into a cleverly low-power underwater autonomous vehicle. In 2016, Alberto Molina took the top spot for DTTO, a modular robotics system made up of multiple single-hinge segments that can reorient themselves. A team working toward an eye-controlled electric wheelchair placed first in 2015 for Eyedriveomatic — a solution that improved life for two of the team members with Motor Neuron Disease, (also called ALS). And the recipients of the first Hackaday Prize were recognized for their team’s development of a network of satellite ground stations (SatNOGS) which anyone can build, add to the network, and share time on to communicate with satellites as they make their orbit. This is an important tool to make low-cost research for things like Cubesats possible, and the network has been growing ever since.
If you feel the need for more inspiration, take a few minutes to look over the Hackaday Prize hall of fame of all of the top finishers through the years.
These are impressive ideas that began with the basic question of how can we do better? A simple idea can change the world but only if you share that idea and work to make it grow. Enter yours in the Hackaday Prize now!
Guess what’ll be wrapping up in just two weeks? The Midwest RepRap Festival, the largest con for open source 3D printing in the world. MRRF is going down in Goshen, Indiana on March 23rd through March 25th. Tickets are free! If you’re looking for a hotel, I can speak from experience that the Best Western is good and close to the con, and I haven’t heard anything bad about the Holiday Inn Express.
Want to go to a convention with even weirder people? Somehow or another, a press release for Contact In The Desert, the largest UFO conference in the world, ended up in my inbox. It’s on the first weekend in June near Cochilla. Why is this significant? Because the greatest people-watching experience you’ll ever see, AlienCon 2018, is happening in Pasadena just two weeks later. The guy with the hair from Ancient Aliens will be at both events. Why are they having a UFO conference where military planes fly all the time? Wouldn’t it be better to rule out false positives?
The entirety of Silicon Valley tech culture is based upon the principle of flouting laws and regulations. We have reached a new high water mark. Swarm Technologies, a ‘stealth startup’ working on ‘Internet of Things’ satellites recently sent up four 0.25U cubesats on an ISRO flight. The satellites were deployed and are currently in orbit. This is somewhat remarkable, because the FCC, the government body responsible for regulating commercial satellites, dismissed Swarm’s application for launch on safety grounds. As reported by IEEE Spectrum, this is the first ever unauthorized launch of commercial satellites.
The TRS-80 Model 100 was one of the first, best examples of a ‘notebook’ computer. It had a QWERTY keyboard, an LCD, and ran off a few AA batteries for 20 hours. It’s the perfect platform for a Raspberry Pi casemod, and now someone has finally done it. [thecodeman] stuffed a Pi into a broken model M100 and replaced the old LCD with a 7.8″ 400×1280 pixel display. The display is the interesting part here, and it comes from EarthLCD, part number earthlcd-7-4001280.
The Flite Test crew is famous for their foam board RC airplanes, but they have historically had some significantly more interesting builds. Can you fly a cinder block? Yep. Can you fly a microwave and have it pop popcorn? Yep. Their latest crazy project is a flying Little Tikes Cozy Coupe, the ubiquitous red and yellow toy car meant to fit a toddler. The wings are made out of cardboard, the motors — both of them — generate thirty pounds of thrust each, and you can weld with the batteries. Does it fly? Yes, until the wings collapsed and the Cozy Coupe plummeted to the ground. Watch the video, it’s a great demonstration of designing a plane to rotate off the ground.
What’s your favorite OpenSCAD command? Perhaps it’s intersection() or difference()? Or are you a polygon() and extrude() modeler? For me, the most useful, and maybe most often overlooked, function is hull(). Hull() does just what it says on the can — creates a convex hull around the objects that are passed to it as children — but that turns out to be invaluable.
Hull() solves a number of newbie problems: making things round and connecting things together. And with a little ingenuity, hull() can provide a nearly complete modelling strategy all on its own. If you use OpenSCAD and your creations end up with hard edges, or you spend too much time figuring out angles, or if you just want to experience another way to get the job done, read on!
What’s the smallest controller you’ve ever used? [BitBuilt] forum user [Madmorda] picked up a cool little GameCube controller keychain with semi-working buttons at her local GameStop. As makers are wont to do, she figured she could turn it into a working controller and — well — the rest is history.
This miniaturized controller’s original buttons were essentially one piece of plastic and all the buttons would depress at once — same goes for the D-pad. Likewise, the original joystick and C-stick lacked springs and wouldn’t return to a neutral position after fidgeting with them. To get the ball rolling, [Madmorda] picked up a GC+ board — a custom GameCube controller board — just small enough to fit this project, eleven hard tact switches for the various buttons, and two squishy tact switches to replicate the original controller’s L and R button semi-analog, semi-digital functionality.
How would you approach a build that required you to hack apart a perfectly good console motherboard? With aplomb and a strong finish. [jefflongo] from [BitBuilt.net] — a forum dedicated to making consoles portable — has finished just such a task, unveiling his version of a portable Wii to the world.
While this bears the general appearance of a portable GameCube, it’s what inside that counts. A heavily modified Wii motherboard — to reduce size — forms this portable’s backbone, and it includes two infrared LEDs on its faceplate for Wii Remotes. A single player can use the built-in controller, but [jefflongo] has included four GameCube controller ports for maximum multiplayer mayhem. Although he’ll likely plan on taking advantage of the built-in AV Out port to play on a TV and charge port for those extended gaming sessions, four 3400mAh batteries — with an estimated four hour battery life — should keep him satisfied on the go until he can recharge.
While the electronics display an impressive amount of work, but the final piece is a sight to behold. Check out the demo video after the break!
If you’ve played Valve’s masterpiece Portal, there’s probably plenty of details that stick in your mind even a decade after its release. The song at the end, GLaDOS, “The cake is a lie”, and so on. Part of the reason people are still talking about Portal after all these years is because of the imaginative world building that went into it. One of these little nuggets of creativity has stuck with [Alexander Isakov] long enough that it became his personal mission to bring it into the real world. No, it wasn’t the iconic “portal gun” or even one of the oft-quoted robotic turrets. It’s that little clock that plays a jingle when you first start the game.
Alright, so perhaps it isn’t the part of the game that we would be obsessed with turning into a real-life object. But for whatever reason, [Alexander] simply had to have that radio. Of course, being the 21st century and all his version isn’t actually a radio, it’s a Bluetooth speaker. Though he did go through the trouble of adding a fake display showing the same frequency as the one in-game was tuned to.
The model he created of the Portal radio in Fusion 360 is very well done, and available on MyMiniFactory for anyone who might wish to create their own Aperture Science-themed home decor. Though fair warning, due to its size it does consume around 1 kg of plastic for all of the printed parts.
For the internal Bluetooth speaker, [Alexander] used a model which he got for free after eating three packages of potato chips. That sounds about the best possible way to source your components, and if anyone knows other ways we can eat snack food and have electronics sent to our door, please let us know. Even if you don’t have the same eat-for-gear promotion running in your neck of the woods, it looks like adapting the model to a different speaker shouldn’t be too difficult. There’s certainly enough space inside, at least.
