2018 Hackaday Prize: Build Hope. Design The Future.

March 12, 2018 by 50 Comments

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.

Build Hope. Design the Future.

This coming Saturday is Hackaday World Create Day, and the perfect time to get started with your Hackaday Prize entry. Stop by a meetup in your area (or host your own) and put your heads together and pick the design challenge you want to work on. We love seeing collaborative entries and this is a great chance to build your engineering dream team.

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!

DIY Planetarium Built From PVC Pipes And Cardboard

March 12, 2018 by 9 Comments

When you think about DIY projects, you probably don’t consider building your own planetarium. Why would you? Building the thing is surely outside the capabilities of the individual, and even if you could figure it out, the materials would be far too expensive. There’s a limit to DIY projects, and obviously building a planetarium is on the wrong side of the line. Right?

Well, apparently not. [Gabby LeBeau] has documented the planetarium she built as her senior project, and if you’ll forgive the pun, it’s absolutely out of this world. Using readily available parts and the help of family and friends, she built a fully functional planetarium big enough to seat the Physics Department. No word on what grade she got, but it’s a safe bet she screwed the curve up for the rest of the class.

After two months of research and a couple of smaller proof of concept builds, she was able to find a business who graciously allowed her to construct the full scale planetarium in their warehouse. The frame is made of PVC pipes held together with zip ties. The big advantage to using the PVC pipes (beyond being cheap and easy to works with) is that they will automatically find a hemispherical shape when bent; saving the time and trouble it would take to create the shape with more rigid building materials.

Once the PVC frame was up, white cardboard panels were cut to shape and attached to the inside. The panels were lined up as closely as possible, but gaps were covered with white tape so the fit didn’t need to be perfect. When the dome was finished, it was lifted and placed on metal trusses to get some room underneath, and finally covered with a black tarp and stage curtain to block out all light.

Of course, she didn’t go through all this trouble to just stick some glow in the dark stars on the inside of this thing. The image from a standard projector is directed at a flat mirror, which then bounces off of a convex mirror. Driving the projector is a laptop running Stellarium. While there were some imperfections she couldn’t get polished or cleaned off of the mirrors, the end result was still very impressive.

Unfortunately, you can’t really do a planetarium justice with a camera, so we aren’t able to see what the final image looked like. But judging by the slack-jawed faces of those who are pictured inside of it, we’re going to go out on a limb and say it was awesome.

We might suggest trying to quiet down the projector or adding some lasers to the mix, but overall this is a truly exceptional project, and we’re jealous of everyone who got to experience it first hand.

On A Quest For The Perfect Numpad

March 12, 2018 by 16 Comments

Often times, the only way to get exactly what you want in a device is to just build it yourself. Well, maybe not the only way, but we’ve all certainly told ourselves it was the only way enough that it might as well be true. We don’t know if the DIY imperative felt by [Olav Vatne] to construct his own Bluetooth mechanical number pad was genuine or self-imposed, but in either event, we’re glad he documented the process for our viewing pleasure.

Broken up into three separate posts on his blog, the construction of his custom numpad starts innocently enough with buying a kit from AliExpress. In a rather bizarre twist, the kit arrived assembled, which lead to an arduous period of desoldering to separate all the principle parts [Olav] wanted in the first place. So much for saving time.

Once he freed all the mechanical keys from the kit’s PCB, he went to town hand-wiring the matrix. After testing to make sure all the keys were wired correctly, the matrix got connected to an Adafruit Feather 32u4 Bluefruit. With the electronics sorted, [Olav] moved on to the software side. Here he was able to accomplish one of his primary goals, having a numpad that works over both USB and Bluetooth.

The last step of the process was creating the wooden enclosure. It basically goes together like a picture frame, with special care given to make sure there are appropriate openings in the case for the switches and USB port to pop through without ruining the overall look of the device.

Thanks to cheap USB-capable microcontrollers, hand-made artisan keyboards are now a thing. This project is a nice way to get started with custom input devices, and it only gets better from here.

Glorious Body Of Tracked ‘Mad Mech’ Started As Cardboard

March 11, 2018 by 10 Comments

[Dickel] always liked tracked vehicles. Taking inspiration from the ‘Peacemaker’ tracked vehicle in Mad Max: Fury Road, he replicated it as the Mad Mech. The vehicle is remote-controlled and the tank treads are partly from a VEX robotics tank tread kit. Control is via a DIY wireless controller using an Arduino and NRF24L01 modules. The vehicle itself uses an Arduino UNO with an L298N motor driver. Power is from three Li-Po cells.

The real artistic work is in the body. [Dickel] used a papercraft tool called Pepakura (non-free software, but this Blender plugin is an alternative free approach) for the design to make the body out of thin cardboard. The cardboard design was then modified to make it match the body of the Peacemaker as much as possible. It was coated in fiberglass for strength, then the rest of the work was done with body filler and sanding for a smooth finish. After a few more details and a good paint job, it was ready to roll.

There’s a lot of great effort that went into this build, and [Dickel] shows his work and process on his project page and in the videos embedded below. The first video shows the finished Mad Mech being taken for some test drives. The second is a montage showing key parts of the build process.

Print, Rinse, Wear. Nanowire Circuits For Your Microfibre Clothing.

March 11, 2018 by 7 Comments

While our bodies are pretty amazing, their dynamic nature makes integrating circuits into our clothing a frustrating process.  Squaring up against this challenge, a team of researchers from North Carolina State University have hit upon a potential boon for wearable electronics: silver nanowires capable of being printed on flexible, stretchy substrates.

It helps that the properties of silver nanowires lend themselves to the needs of wearable circuits — flexible and springy in their own right — but are not without complications. Silver nanowires tend to clog print nozzles during printing, so the research team enlarged the nozzle and suspended the nanowires in a water-soluble solvent, dramatically cutting the chance of clogging. Normally this would have a negative impact on precision, but the team employed electrostatic force to draw the ink to the desired location and maintain print resolution. Once printed, the solvent is rinsed away and the wearable circuit is ready for use.

By controlling print parameters — such as ink viscosity and concentration — the team are able to print on a wide variety of materials. Successful prototypes thus far include a glove with an integrated heating circuit and an electrocardiograph electrode, but otherwise the size of the printer is the only factor limiting the scale of the print. Until this technique becomes more widely available, interested parties might have to put their stock into more homebrew methods.

[Thanks for the tip, Qes!]

Hackaday Links: March 11, 2018

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.

Is That A Mars Habitat? A Submarine? A Spaceship? Nope: It’s Home.

March 11, 2018 by 26 Comments

[Jan Körbes], an architect living with his daughter in Berlin, specializes in recycling materials. Inspired by discarded grain silos he saw across the Netherlands, he converted one into a micro-home that you would almost expect to see on the surface of mars. The guided tour in the video below give a pretty good feel for the space station feel of the abode.

A lot of the silo house’s design was inspired by [Körbes’] childhood of growing up on boats. It’s exceptionally functional and nearly every nook and cranny of the home can be altered, repurposed, and changed back. For instance: the two pantries on the main floor used to the toilet and shower, but since the silo home is currently set up at ZK/U — Center for Arts and Urbanistics in Berlin — they make use of the facilities there instead.

True to his specialization of creative recycling , a lot of the materials for the house were either donated, or bought at a steep discount due to various reasons. For instance, the windows were a small, unpopular size for most houses but work well here. This led to an evolving design of the house as it was being built, but everything [Körbes] and his daughter need is present inside of fourteen square metres on three floors.

Under the floor on the main level is a bathtub with infrared heating — the cover doubling as the dining table with feet dangling into the tub underneath. The kitchen has a small oven, an old camp stove, and fridge — enough for two people — and the sink uses a foot-activated button so the [Körbes’] use only as much water as they need. A nearby small wood stove with an extendable wood storage basket heats the space.

The house’s electrical (including a solar battery) and water systems are tucked into the basement beside the books, keeping the heavier objects low in such a tall and narrow dwelling. Larger rainwater collection tanks (a hack we’re quite fond of) surrounding the silo house also add ballast in case of storm.

With a two metre ceiling height on the main floor and nearly as much in the bunking quarters upstairs — accessed by a climbing wall, [Körbes] says the space feels much larger than you would expect. Large enough, at least, to host a standing record of a 38-person party. It’s fun to see the ingenuity that goes into tiny living space design. If you missed it, check out these CNC plywood designs for building homes.
