When it comes to vintage displays, everyone gravitates to Nixies. These tubes look great, but you’re dealing with a certain aesthetic with these vintage numeric tubes. There is another option. For his Hackaday Prize entry, [castvee8] is making seven-segment displays out of vintage neon lamps. It looks great, and it’s the basis of an all-vacuum tube calculator.
The core of this build are a few tiny NE-2 neon bulbs. These are the same type of bulbs you’ll find in old indicators, and require somewhere around 100 volts to fire. These bulbs are then installed in a 3D-printed frame, giving [castvee] a real seven-segment display, a plus or minus sign, and an equals sign. It’s the beginnings of a calculator, right there.
One of the recent updates to this project is controlling these displays with modern logic. That might be a bit of a misnomer, because [castvee] is using diode steering and a TTL chip to cycle through the numbers 1 to 4. The actual code to do this is running on a microcontroller, though, so that might get a pass. This is just a test, though, and the real project looks to be an all-vacuum calculator. The project is still in its early stages, but there are still months to go in the Hackaday Prize, and we can’t wait to see what comes out of this project.
For this week’s Hack Chat, we’re talking all about the Hackaday Prize. Our guests for this week’s Hack Chat are Alberto Molina and Elecia White.
Elecia White was a Hackaday Prize judge in 2015 and 2016, and she’ll be discussing what makes a standout entry from a judging perspective. Elecia is an embedded software engineer at Logical Elegance, Inc., author of Making Embedded Systems, and host of the Embedded.fm podcast.
Alberto Molina won the Grand Prize of the 2016 Hackaday Prize with Dtto, an Open Source, self-reconfiguring rescue robot that Alberto is continuing to develop. Alberto is an Electronic engineer who wants to design the next generation of robots and he will share his insights on putting together a fantastic entry for your project.
The Hackaday Prize is the greatest hardware competition ever. It’s the Academy Awards of Open Hardware (and will remain so until we get a cease and desist). The Hackaday Prize is a competition where thousands of hardware hackers, makers, and artists compete to build a better future.
The Hackaday Prize is in its fifth year in 2018, and the theme this year is Build Hope. We’re challenging everyone to put your ideas and creativity to use and Build Something That Matters. Do this, and you’ll be in the running for the Grand Prize of $50,000. In total we’re giving away $200,000 in total cash prizes to build hardware, something no other hardware competition can match.
Also on board for this Hack Chat, like all Hack Chats, will be Stephen Tranovich, Technical Community Leader at Hackaday.io. Steven has been working hard on the logistics for the Prize this year, and will field any and all questions about entering the 2018 Hackaday Prize.
In this Hack Chat, we’ll be discussing how the Prize is judged, the new challenges for the 2018 Hackaday Prize, the achievements the winners of the Hackaday Prize have already seen, and of course, your questions. We know there’s a lot of interest in the Hackaday Prize, and we want you to ask what’s on your mind. If you have a question, just add it to the Hack Chat event page as a comment, and we’ll answer it.
Our Hack Chats are live community events on the Hackaday.io Hack Chat group messaging. This week it’s going down at the usual time, on noon, Pacific, Friday, March 23rd Want to know what time this is happening in your neck of the woods? Have a countdown timer!

Oh, boy. You know what’s happening next weekend?The Midwest RepRap Festival. The greatest 3D printing festival on the planet is going down next Friday afternoon until Sunday afternoon in beautiful Goshen, Indiana. Why should you go? Check this one out. To recap from last year, E3D released a new extruder, open source filaments will be a thing, true color filament printing in CMYKW is awesome, and we got the world’s first look at the infinite build volume printer. This year, The Part Daddy, a 20-foot-tall delta bot will be there once again. It’s awesome and you should come.
We launched the 2018 Hackaday Prize this week. Why should you care? Because we’re giving away $200,000 in prizes. There are five challenges: the Open Hardware Design Challenge, Robotics Module, Power Harvesting, Human-Computer Interface, and Musical Instrument Challenge. That last one is something I’m especially interested in for one very specific reason. This is a guitorgan.
Building a computer soon? Buy your SSD now. Someone fell asleep on the e-stop at a Samsung fab, and now 3.5% of global NAND production for March has been lost.
Need to put an Arduino in the cloud? Here’s a shield for that. It’s a shield for SIMCom’s SIM7000-series module, providing LTE for a microcontroller. Why would you ever need this? Because 2G is dead, for various values of ‘dead’. 3G is eventually going to go the same way.
A bridge collapsed in Florida this week. A pedestrian walkway at Florida International University collapsed this week, killing several. The engineering efforts are still underway to determine the cause of the accident, but some guy from Canukistan posted a pair of informative videos discussing I-beams and pre-tensioned concrete. It’s going to be months until the fault (and responsibility) will be determined, but until then we have the best footage yet of this collapse. It’s dash cam footage from a truck that rolled up to the red light just before the collapse. This is one that’s going to go down in engineering history along with the Hyatt Regency collapse.
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.
We have five challenge categories to choose from in the 2018 Hackaday Prize. The top twenty entries from each category will receive $1,000 and continue work in order to compete for the top prizes.

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!
It is extremely distressing to watch someone succumb to an uncontrollable hand tremor. Simple tasks become frustrating and impossible, and a person previously capable becomes frail and vulnerable. Worse still are the reactions of other people, in whom the nastiest of prejudices can be unleashed. A tremor can be a debilitating physical condition, but it is not one that changes who the person afflicted with it is.
An entry from [Basian Lesi] in this year’s Hackaday Prize aims to tackle hand tremors, and it takes the form of a wearable device that tries to correct the tremors by applying small electrical stimuli in response to the motion it senses from its built-in accelerometer. At its heart is an ATMega328p microcontroller and an MPU6050 accelerometer chip, and the prototype is shown using a piece of stripboard mounted in a 3D-printed box. It’s still in development and testing, but they have posted a video showing impressive results that you can see below the break, claiming an 85% reduction in tremors.
It is difficult to put yourself as an able-bodied person into the experiences of a person with a physical disability. Able-bodied people are quick with phrases such as “Confined to a wheelchair” with little idea of what that really means, and might be surprised to meet wheelchair users who would point out that far from being a prison their chair might, in fact, be their tool of liberation.
It is also difficult for an able-bodied person to understand some of the physical effects of using a wheelchair. In particular, some wheelchair users with paralysis can suffer from dangerous pressure sores without being aware of them due to their loss of feeling. Such people, therefore, have a regime of exercises designed to relieve the pressure that causes the sores, and these exercises must be completed as often as every half hour. They can be inconvenient and difficult to perform, so in an effort to help people in that position there is a Hackaday Prize entry that provides feedback on how effectively the exercise regime has been performed.
The project puts an array of force-sensitive resistors on the bed of the chair underneath its cushion and monitors them with an Arduino before giving a feedback to the user via a set of LEDs. So far they have created a first prototype, and are awaiting parts and recruiting users for testing a second.
It would be nice to think that this project would have a positive impact on the lives of the people it aims to help. It’s not the first time the Hackaday Prize has ventured into this field, as the 2015 winner demonstrates.
Hey, you know what’s happening right now? We’re wrapping up the third round of The Hackaday Prize. This challenge, Wheels, Wings, and Walkers, is dedicated to things that move. If it’s a robot, it qualifies, if it’s a plane, it qualifies, if it passes butter, it qualifies. There’s only a short time for you to get your entry in. Do it now. Superliminal advertising.
Speaking of the Hackaday Prize, this project would be a front-runner if only [Peter] would enter it in the competition. It’s one thing to have a cult; I have a cult and a petition to ‘stop’ me.
We were completely unaware of this project, but a few weeks ago, a cubesat was launched from Baikonur. This cubesat contains a gigantic mylar reflector, and once it’s deployed it will be the second brightest object in the night sky after the moon. I don’t know why we haven’t seen this in the press, but if you have any pictures of sightings, drop those in the comments.
In a mere two years, we’ll be looking at the 50th anniversary of the Apollo 11 landing. The mission control center at Johnson Space Center — where these landings were commanded and controlled — is still around, and it’s not in the best shape. There’s a Kickstarter to restore the Apollo Mission Control Center to its former glory. For the consoles, this means restoring them to Apollo 15 operational configuration.
We’ve seen 3D printed remote control airplanes, and at this point, there’s nothing really exceptional about printing a wing. This user on imgur is going a different direction with 3D printed fiberglass molds. Basically, it’s a fuselage for a Mustang that is printed, glued together, with the inside sanded and coated in wax. Two layers (3 oz and 6 oz) fiberglass is laid down with West Systems epoxy. After a few days, the mold is cracked open and a fuselage appears. This looks great, and further refinements of the process can include vapor smoothing of the inside of the mold, a few tabs to make sure the mold halves don’t break when the part is released, and larger parts in general.

This week is Def Con. That means two things. First, we’re on a hardware hunt. If you’ve been dedicating the last few months to #badgelife or other artisanal electronics, we want to hear about it. Second, [Joe Kim] made a graphic of the Tindie dog wearing a Hackaday hoodie and it’s adorable. There are a limited number of stickers of our hacker dog.
Gigabyte launched a single board computer with an Intel Apollo Lake CPU, discrete memory and storage, and a mini PCIe slot. Of course, this is being incorrectly marketed as a ‘Raspberry Pi competitor’, but whatever.
