What Actually Happens At A Hardware Hacking Con

The Hackaday Superconference was last weekend, and it was the greatest hardware con on the planet. What can you build out of a conference badge? If you answered “a resin-based 3D printer” you would have won a prize. If you decided to put your badge in a conference water bottle and make a stun gun you’d receive adoration of all in attendance. Yeah, it got that crazy.

At other tech conferences, you’ll find gaggles of nerds sitting around a table with MacBooks and Thinkpads. The Superconference is different. Here, you’ll find soldering irons, tackle boxes filled with components, and loose …read more

Goodbye, TechShop

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 …read more

The Hacker Village of Supercon

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 …read more

The Perils of Developing the Hackaday Superconference Badge

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 …read more

Organizing Teams With Collective Fictions

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 …read more

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

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.

Much more recently, there has been interest in transcranial direct current …read more

Hacking When it Counts: Prison Locksmithing

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 …read more

Review: JYE Tech DSO150 Oscilloscope Kit

Do you remember your first oscilloscope? Maybe we have entered the era in which younger readers think of a sleek model with an LCD screen, but for the slightly older among us the image that will come to mind is likely to be a CRT-based behemoth. Mine was a 2MHz bandwidth Cossor from the 1950s, wildly outdated by the 1980s, but it came to me at no cost. It proudly proclaims itself as a “Portable Oscillograph”, but requires its owner to be a weightlifter to move it. I still have it, as a relic and curio.

For most of us …read more

How The Integrated Circuit Came To Be

As the saying goes, hindsight is 20/20. It may surprise you that the microchip that we all know and love today was far from an obvious idea. Some of the paths that were being explored back then to cram more components into a smaller area seem odd now. But who hasn’t experienced hindsight of that sort, even on our own bench tops.

Let’s start the story of the microchip like any good engineering challenge should be started, by diving into the problem that existed at the time with the skyrocketing complexity of computing machines.

The Problem: Tyranny Of Numbers

The …read more

How Pure is this Cup of Joe? Coffee, Conspiracy, and Citizen Science

Have you ever thought about coffee purity? It’s more something you’d encounter with prescription or elicit drugs, but coffee is actually a rather valuable commodity. If a seller can make the actual grounds go a bit further by stretching the brew with alternative ingredients there becomes an incentive to cheat.

If this sounds like the stuff rumors are made of, that’s because it is! Here in Ho Chi Minh City there are age-old rumors a coffee syndicate that masterfully passes off adulterated product as pure, high-grade coffee. Rumors are one thing, but the local media started picking up on these …read more
