Goodbye, TechShop

November 17, 2017 by DJ Harrigan 112 Comments

The CEO of TechShop, [Dan Woods], has hit the legal E-stop and declared Chapter-7 bankruptcy for the business. All ten US locations were shuttered on Wednesday with absolutely no advance warning. You can read the full statement from [Dan] here.

We are deeply saddened to hear of TechShop’s closing, and while it wasn’t implausible that this might happen someday, the abrupt shuttering must come as a painful shock to many for whom TechShop was an important part of their personal and professional lives. We owe a lot to the work and effort they put forth; they led the way as a pioneering makerspace and for more than ten years, TechShop provided access to tools, taught classes, and created opportunities for the DIY world that are still as important today as they were in the mid-aughts.

Leading the Way

Jim Newton, founder of TechShop, originally wanted a space to tinker with his pet projects. “I’m a frustrated inventor who needs to have access to this kind of stuff. And people always say that the best companies are the ones where the founders are passionate about what they are creating, which is exactly what I am,” Jim said in an interview in 2007, at the beginnings of TechShop.

It turned out that there were a lot of other tinkerers who wanted to work their pet projects too.

TechShop took a risk. All new business ventures are risky and most fail quite quickly, but in 2006, this whole movement, this idea that people could build things and take advantage of new technologies, personal fabrication, ad-hoc manufacturing, and rapid prototyping outside of universities and commercial R&D labs, was just a dream.

Adafruit was incubating in Limor’s dorm room. Arduino was just the name of some pub in Italy. Eben Upton was wiring prototype Raspberry Pi’s by hand. Nathan Seidle was still reflowing Sparkfun’s boards with a toaster oven. Maker Faire, “The World’s Largest Show and Tell,” wouldn’t even launch until the following year.

In the fading light of high school shop classes, people often were shown the ways of woodworking, light metalwork, and maybe how to fix a car or two. Filling a business with a smorgasbord of advanced machinery and teaching people how to use it, was, and still is, a relatively new concept. TechShop had a dream and made it real with the dedication of hardworking support staff and instructors around the country. Continue reading “Goodbye, TechShop” →

The Hacker Village Of Supercon

November 16, 2017 by Mike Szczys 9 Comments

I’m utterly exhausted and still in a state of awe. The Hackaday Superconference has grown in so many ways, but one thing remains the same: the spirit of the Hacker Village — an intangible feeling that grows up around all who attend — is bliss to take part in.

There’s really no substitute for having been there in person. I’ll go into detail below and try to share the experience as best I can. But the gist of the atmosphere is this: everyone at Supercon is the type of person you’d want to be stuck in a rowboat with, or partnered with on an engineering project, or to have next to you while trying to save the world. There are no looky-loos at Supercon. It turns out we are all stuck in a rowboat together, we are all working on engineering projects, and we are all trying to save the world. And when we all get together it feels like a drug our pragmatic minds never knew existed. This is the recharge for that sense of urgency that keeps you going all year long.

So yes, you really missed it. But start now. Become friends with all of these people over the next year. Begin building your Supercon community now and it’ll feel like a reunion when it rolls around again next November.

The Perils Of Developing The Hackaday Superconference Badge

November 15, 2017 by Brian Benchoff 22 Comments

In case you haven’t heard, the best hardware conference in the world was last weekend. The Hackaday Superconference was three days of hardware hacking, soldering irons, and an epic hardware badge. Throw in two stages for talk, two workshop areas, the amazing hallwaycon and the best, most chill attendees you can imagine, and you have the ultimate hardware conference.

Already we’ve gone over the gory details of what this badge does, and now it’s time to talk about the perils of building large numbers of an electronic conference badge. This is the hardware demoscene, artisanal manufacturing, badgelife, and an exploration of exactly how far you can push a development schedule to get these badges out the door and into the hands of eager badge hackers and con attendees.

The good news is that we succeeded, and did so in time to put a completed badge in the hand of everyone who attended the conference (and we do have a few available if you didn’t make it to the con). Join me after the break to learn what it took to make it all happen and see the time lapse of the final kitting process.

Organizing Teams With Collective Fictions

November 14, 2017 by Christian Trapp 38 Comments

There is often an observable difference between what is considered the right thing to do, and what actually is being done.

Terry Pratchett said it best when he made Death declare mercy and justice nonexistent: “TAKE THE UNIVERSE AND GRIND IT DOWN TO THE FINEST POWDER AND SIEVE IT THROUGH THE FINEST SIEVE AND THEN SHOW ME ONE ATOM OF JUSTICE, ONE MOLECULE OF MERCY.” (Note that Death is not shouting, he simply speaks upper case.)

We can’t measure justice and mercy. These are collective fictions — things we agree to believe to enable us to get along — and finding consensus on the immeasurable extends to political systems, religion, and most of economics. In a recent article [zwischenzugs] makes the point that methodologies in software development fall into the same category. Like collective societal fictions, methodologies tend to elicit strong emotional responses among those dealing with them.

A software development methodology is a playbook for getting from nothing to something. It’s a control system for how people working on the project spend their time. And there are a lot of these prescribed methods, from Agile to Waterfall, and any combination of letters is likely to turn an abbreviation for a methodology. An interesting game when hanging out in groups of software engineers is to start the “Have you ever tried the…” conversation. Just don’t expect to move to another topic anytime soon.

One disheartening aspect of methodologies is their resistance to scientific scrutiny. Two samples of development teams will differ wildly in so many characteristics that a meaningful comparison of the way they organize their work is not possible. Which will leaves us with anecdotes and opinions when discussing these things.

Current opinions regarding the impact of methodologies on the success of a project range from ‘marginal’ to ‘essential’. The latter position is mainly propagated by consultants selling agile certifications, so you may want to take it with a grain of salt. Whether a team adheres strongly to the methodology or adopts it in name only, it’s obvious they serve a purpose — but that purpose may not match the face value of the method.

Shockingly, DARPA’s Brain Stimulator Might Not Be Complete Nonsense

November 13, 2017 by Sean Boyce 53 Comments

Where does your mind jump when you hear the mention of electroshock therapy? The use of electrical current to treat various medical conditions has a long and controversial history. Our fascination with the medical applications of electricity have produced everything from the most alarming of patent medicines to life-saving devices like pacemakers and the Automatic External Defibrillator.

The oldest reference I could find is the use of the torpedo fish to allegedly cure headaches, gout, and so on in 43 CE. Incidentally, Torpedo torpedo is an awesome species name.

Dosage: Apply live fish as needed to face? Source

Much more recently, there has been interest in transcranial direct current stimulation (tDCS). In essence, it’s a technique by which you pass an electrical current (typically about 2 milliamps) between strategically positioned electrodes on your head. The precise reason to do this is a bit unclear; different journal articles have suggested improvements in cognition, learning, and/or the potential treatment of various diseases.

I think most of us here spend a lot of time studying. The idea that a simple, noninvasive device can accelerate that is very attractive. We’ve covered a few people building their own such devices.

Unfortunately, what we want to be true is irrelevant. Superficially, this looks like a DARPA-funded panacea with no clearly established mechanism of action. Various commercial products are being sold that imply (but as usual, don’t directly state) that tDCS is useful for treating pretty much everything, with ample use of ‘testimonials’.

While tDCS can be prescribed by a physician in some countries to complement a stroke rehabilitation regime, for off-label purposes you may as well just go apply a fish to your face. Let’s dig into the literature and products that are out there and see if we can find the promise hiding amidst the hype.

Open Source Underwater Glider Wins 2017 Hackaday Prize

November 11, 2017 by Brian Benchoff 8 Comments

The Open Source Underwater Glider has just been named the Grand Prize winner of the 2017 Hackaday Prize. As the top winner of the Hackaday Prize, the Open Source Underwater Glider will receive $50,000 USD completes the awarding of more than $250,000 in cash prizes during the last eight months of the Hackaday Prize.

More than one thousand entries answered the call to Build Something That Matters during the 2017 Hackaday Prize. Hardware creators around the globe competed in five challenges during the entry rounds: Build Your Concept, Internet of Useful Things, Wings-Wheels-an-Walkers, Assistive Technologies, and Anything Goes. Below you will find the top five finisher, and the winner of the Best Product award of $30,000.

Open Source Underwater Glider

Grand Prize Winner ($50,000 USD): The Open Source Underwater Glider is an AUV (Autonomous Underwater Vehicle) capable of long-term underwater exploration of submarine environments. Where most AUVs are limited in both power and range, the Open Source Underwater Glider does not use active propulsion such as thrusters or propellers. This submersible glides, extending the range and capabilities of whatever task it is performing.

The Open Source Underwater Glider is built from off-the-shelf hardware, allowing anyone to build their own copy of this very capable underwater drone. Extended missions of up to a week are possible, after which the Glider would return home autonomously.

Connected Health: Open source IoT patient monitor

Second Place ($20,000): The Connected Health project aims to bring vital sign monitoring to the masses with a simple, inexpensive unit built around commodity hardware. This monitoring system is connected to the Internet, which enables remote patient monitoring.

Assistance System for Vein Detection

Third Place ($15,000): This Assistance System for Vein Detection uses off-the-shelf components and near-IR imaging to detect veins under the skin. This system uses a Raspberry Pi and camera module or a modified webcam and yet is just as reliable as professional solutions that cost dozens of times more than this team’s prototype.

Adaptive Guitar

Fourth Place ($10,000): The Adaptive Guitar is an electromechanical system designed to allow disabled musicians to play the guitar with one hand (and a foot). This system strums the strings of a guitar while the musician frets each string.

Tipo : Braille Smartphone Keypad

Fifth Place ($5,000): Tipo is effectively a Braille USB keyboard designed for smartphones. The advent of touchscreen-only phones has unfortunately left the visually impaired without a modern phone. Tipo allows for physical interaction with modern smartphones.

Best Product Winner: Tipo : Braille Smartphone Keypad

The winner of the Best Product is Tipo : Braille Smartphone Keypad. Tipo is the solution to the problem of the increasingly buttonless nature of modern smartphones. A phone that is only a touchscreen cannot be used by the visually impaired, and Tipo adds a Braille keypad to the back of any phone. It is effectively a USB keypad, designed for Braille input, that attaches to the back of any phone.

The Best Product competition ran concurrently with the five challenge rounds and asked entrants to go beyond prototype to envision the user’s needs, manufacturing, and all that goes into getting to market. By winning the Best Product competition, the creators of Tipo will refine their design, improve their mechanical build, start looking at injecton molding, and turn their 3D printed prototype into a real product that has the ability to change lives.

Congratulations to all who entered the Hackaday Prize. Taking time to apply your skill and experience to making the world better is a noble pursuit. It doesn’t end with the awarding of a prize. We have the ability to change lives by supporting one another, improving on great ideas, and sharing the calling to Build Something that Matters.

Hacking When It Counts: Prison Locksmithing

November 10, 2017 by Dan Maloney 28 Comments

In 1978, Tim Jenkin was a man living on borrowed time, and he knew it. A white South African in his late 20s, he had been born into the apartheid system of brutally enforced racial segregation. By his own admission, he didn’t even realize in his youth that apartheid existed — it was just a part of his world. But while traveling abroad in the early 1970s he began to see the injustice of the South African political system, and spurred on by what he learned, he became an activist in the anti-apartheid underground.

Intent on righting the wrongs he saw in his homeland, he embarked on a year of training in London. He returned to South Africa as a propaganda agent with the mission to spread anti-apartheid news and information to black South Africans. His group’s distribution method of choice was a leaflet bomb, which used a small explosive charge to disperse African National Congress propaganda in public places. Given that the ANC was a banned organization, and that they were setting off explosives in a public place, even though they only had a few grams of gunpowder, it was inevitable that Jenkin would be caught. He and cohort Steven Lee were arrested, tried and convicted; Jenkin was sentenced to 12 years in prison, while Lee got eight.
