This excellent content from the Hackaday writing crew highlights recurring topics and popular series like Linux-Fu, 3D-Printering, Hackaday Links, This Week in Security, Inputs of Interest, Profiles in Science, Retrotechtacular, Ask Hackaday, Teardowns, Reviews, and many more.
Mike Szczys is on a well-deserved vacation this week, so staff writer Dan Maloney joins managing editor Elliot Williams for a look at all the great hacks of the week. On this episode we’re talking about licensing fees for MIDI 2.0, a two-way fail while snooping on employees, and the potential for diagnosing Alzheimer’s with virtual reality. We also dive into the well-engineered innards of a robotic cheetah, a personal assistant safe enough for kids to use, and how listening to your monitor reveals more about you than you’d think. You don’t want to miss a space nerd’s quest for fire or a hacker’s guide to solder and soldering. And you’ve got to catch the story of a hapless hacker’s contact high from a vintage synthesizer. It’s quite a trip.

The artistic elite exists in a stratum above we hoi polloi, a world of achingly trendy galleries, well-heeled collectors, and art critics who act as gatekeepers to what is considered the pinnacle du jour of culture. Artistic movements that evolve outside this bubble may be derided or ignored as naive and unsophisticated, even in complete denial of their raw creative edge. When they are discovered by the establishment a few of their artists are selected and anointed, while inevitably the crucible in which they were formed is forgotten. On the streets of Bristol the incredible work of far more graffiti artists can be seen than just that of Banksy.
Our community has an art form all of its own, in the guise of PCB artwork and the #BadgeLife community. One day you will see electronic badges from darlings of the art world behind glass in those trendy galleries, but for now they live in glorious abundance in the wild. Here at Hackaday we are lucky enough to have in Brian Benchoff a colleague who is pushing the boundaries of PCB art, and at the Hackaday Superconference he took us through one of his more recent pieces of work.
Brian’s pad printer.
The colour palette of a typical printed circuit board is limited by the combination of fibreglass, copper, soldermask, plating, and silkscreen its designer selects. Thus while the variety of soldermask colours and plating materials can make for an eye-catching work, they have remained a colour-tinted near monochrome. The Holy Grail of the PCB artist has been to step into the world of full colour, and Brian has been pursuing that goal by exploring pad printing to produce extra colours beyond the sodermask..
It’s a subject he’s written about here in the past, and he introduces it in the talk with a look at existing badge artwork and a mention of an expensive commercial inkjet process before considering the type of printing you see daily on the sides of promotional pens. Those company titles are deposited on pens using pad printing, an offset process in which ink is first deposited upon a photo-etched metal plate before being picked up on a silicone rubber pad for transfer to the object to be printed. It’s not the panacea for all coloured-PCB tasks, but for adding relatively small blocks of pigment to an otherwise monochromatic board it can be very successful.
The eye-catching Kiss -themed Tindie badges.
Brian’s examples are a panelised set of Tindie badges as a homage to the rock band Kiss, and his Tide pod addon containing a serial number in an EEPROM that was part of a Blockchain-inspired game. The Kiss Tindie badges use black soldermask with extensive white silkscreen and a modest area of red pad printing for the stage makeup, while the Tide addon makes clever use of the same swoosh printed in alternate colours at 180 degrees to each other.
In both cases there is some labour involved in creating the prints, and as his detailed write-up of printing the Tide pods reminds us, the process of creating the printing plate is not exactly an easy one. But it remains the best way yet to add extra colours to a board without paying a small fortune for the inkjet process, and if you’d like to put your own designs at the bleeding edge of PCB art you might wish to read his writeups and watch the video below the break.
This is just one example of the kind of manufacturing techniques, and electronic design principles on display at the Hackaday Superconference. There’s another Supercon just around the corner, so grab your ticket and send in your own talk proposal right away!
In the “Automate the Freight” series, I’ve concentrated on stories that reflect my premise that the killer app for self-driving vehicles will not be private passenger cars, but will more likely be the mundane but necessary task of toting things from place to place. The economics of replacing thousands of salary-drawing and benefit-requiring humans in the logistics chain are greatly favored compared to the profits to be made by providing a convenient and safe commuting experience to individuals. Advances made in automating deliveries will eventually trickle down to the consumer market, but it’ll be the freight carriers that drive innovation.
While I’ve concentrated on self-driving freight vehicles, there are other aspects to automating the supply chain that I’ve touched on in this series, from UAV-delivered blood and medical supplies to the potential for automating the last hundred feet of home delivery with curb-to-door robots. But automation of the other end of the supply chain holds a lot of promise too, both for advancing technology and disrupting the entire logistics field. This time around: automated packaging lines, or how the stuff you buy online gets picked and wrapped for shipping without ever being touched by human hands.
Do you know what your router is doing? We have two stories of the embedded devices misbehaving. First, Linksys “Smart” routers keep track of every device that connects to its network. Right, so does every other router. These routers, however, also helpfully expose that stored data over JNAP/HNAP.
Some background is needed here. First, HNAP is the Home Network Administration Protocol, designed to manage routers and network devices. Originally designed by Pure Networks, HNAP is a SOAP based protocol, and has been part of securityproblems in the past. You may also see the term JNAP. It seems that JNAP is the JSON Network Administration Protocol, identical to HNAP except for using JSON instead of SOAP.
The odd part is that this is an old problem. CVE-2014-8244 was disclosed and fixed in 2014. According to the writeup at Badpackets.net, the problem was re-discovered as a result of observing active network attacks targeting JNAP. When Linksys was informed of the rediscovered problem, they responded that the problem was fixed in 2014, and devices with updated firmware and default settings are not accessible from the public internet. The presence of over 20,000 devices leaking data casts doubt on their response. Continue reading “This Week In Security: Zombieload, And Is Your Router Leaking?”→
Stop what you’re doing and get your ticket to the Hackaday Superconference. This is the ultimate hardware conference, November 15th, 16th, and 17th in Pasadena, California. It will sell out, especially the early bird tickets which are certain to be snapped up before the end of this day. (Edit: Early Bird tickets are already sold out, but you can still get the Early Bird price by submitting a talk).
Supercon is all about hardware creation. From prototypes and manufacturable designs, to one-off hardware art and products that have sold thousands, this is where you meet the people and hear the stories behind new and interesting feats of engineering. It’s a weekend filled with fascinating talks and mind-expanding workshops, but Supercon is so much more.
This is a Hacker Village where the greenest beginner and the grayest veteran sit shoulder to shoulder to solder, to code, to dream of the future, and to share stories of the past. We want you here, and you need to make it happen. Whether it’s professional development (yes! ask your boss to make this a business outing) or your hard-earned vacation, Supercon will recharge your batteries and top off your inspiration for the year to come.
Yes, I’m talking to you. Core to the mission of the Hackaday Superconference is to encourage more people to speak publicly about everything that goes into designing and manufacturing hardware. This means we want first time speakers just as much as we want seasoned presenters. You will be celebrated at Supercon; the ethos of this community is warm, welcoming, and thankful that you took the time to help everyone learn something interesting.
Don’t stop to ask yourself if you should… yes, we want to read your talk proposal. No topic is too big or too small for consideration. This is your chance to give back as a thank-you to so many people who have helped you gather your own skills over the years. We stand on the shoulders of giants, it’s your turn to be giant.
True Believer Tickets
We like to think of our Early Bird tickets as a nod to the true believers out there. We haven’t published the speakers, the workshops, or really anything else. That info will be public as everything comes together, but by then it may be too late to get a ticket. Right now all we can tell you for certain is that there will be a big celebration to name the grand prize winner of the 2019 Hackaday Prize, there will be a ton of badge hacking on a mind-blowing hardware badge being designed by Sprite_TM (Jeroen Domburg), you will have way too much fun and get far too little sleep, and tickets will sell out. In other words, this will be awesome.

Need more convincing? You can watch the recap video from 2018, or dive into the weekend overview, badge-hacking, and competitive soldering roundups. I’ve never met anyone from the first four years of Supercon who regretted buying early bird tickets. I’ve met plenty of people who regretted missing out. Don’t miss out on year five of the movement. This is your community, there is truly something for everyone, and Pasadena is a beautiful place to be in the middle of November. See you at Supercon!
Of the early crop of personal computers that made their way to market before IBM and Apple came to dominate it, few machines achieved the iconic status that the Sinclair ZX80 did.
Perhaps it was its unusual and appealing design style, or maybe it had more to do with its affordability. Regardless, [Sir Clive]’s little machine sold north of 100,000 units and earned a place in both computing history and the hearts of early adopters.
Spencer Owen is one who still holds a torch for the ZX80, so much so that in 2013, he hatched a seemingly wacky idea to make his own. A breadboard prototype of the Z80 machine slowly came to life over Christmas 2013, one thing led to another, and the “RC2014” was born.
The RC2014 proved popular enough to sell on Tindie, and Spencer is now following his dream as a retrocomputing mogul and working on RC2014 full time. He’ll be joining us to discuss the RC2014, how it came to be, and how selling computing nostalgia can be more than just a dream.

We take the everyday materials of engineering for granted, as ubiquitous components rather than as complex items in their own right. Sure, we know that an integrated circuit represents the pinnacle of a hundred years’ development in the field of electronics, but to us it’s simply a black box with some wires. Even with more basic materials it’s easy to forget the work that goes into their manufacture, as for example with the two videos below the break. They both take a look from a very different angle at the creation of the same product: metal chain. However, the approaches couldn’t be more different as the two examples are separated by about a century and with vastly different techniques and material.
The first film follows the manufacture of the chain and anchor that would have been found on a ship around the turn of the twentieth century. One of the text frames mentions Netherton Works, allowing us to identify it as being filmed at N. Hingley & Sons, a specialist anchor and chain manufacturer based in the area to the west of the English city of Birmingham known as the Black Country. It’s a window on a manufacturing world that has entirely disappeared, as large gangs of men do almost every task in the process by hand, with very few automated steps. There is scant regard for health and safety in handling the huge pieces of red-hot metal, and the material in question is not the steel we’d be used to today but wrought iron. The skill required to perform some of the steps such as forge-welding large anchor parts under a steam hammer is very significant, and the film alone can not convey it. More recent videos of similar scenes in Chinese factories do a better job.
The other video is contemporary, a How It’s Made look at chain manufacture. Here the chains involved are much smaller, everything is done by automated machinery, and once we have got over marveling at the intricacy of the process we can see that there is far more emphasis on the metallurgy. The wire is hard drawn before the chain is formed, and then hardened and annealed in a continuous process by a pair of induction heaters and water baths. I’m trying really hard to avoid a minor rant about the propensity of mass-market entertainment such as this for glossing over parts of the process. A keen eye notices that each link has become welded but we are not shown the machine that performs the task.
Most of us will never have the chance of a peek into a chain factory, so the medium of YouTube industrial films and videos is compulsive viewing. These two views of what is essentially the same process could not be more different, however it would be wrong to assume that one has replaced the other. There would have been mechanised production of small chains when the first film was made, and large chains will still be made today with fewer workers and from arc-welded steel rather than wrought iron. Plants like the Hingley one in Netherton may have closed in the 1980s, but there is still a demand for chains and anchors.
