The Case For A Technology Aware Lobby Correspondent

November 17, 2023 by Jenny List 24 Comments

We cover all manner of stories here at Hackaday, including awesome hardware hacks, the latest trends and inventions, and in-depth guides to fascinating technologies. We also cover a few news stories from the wider world outside our community, usually when they have some knock-on effect that has an impact on us. Recently this last category of stories has included laws which present a threat to online encryption and privacy in the UK and in the European Union, for example. They’re not the most joyful of news, but it’s vital for everyone with an interest in online matters to be informed about them.

A Long And Inglorious History

Those of us who have followed the world of technology will know that badly thought out laws with a negative impact on technology have a long and inglorious history. Some like the infamous backdoored Clipper chip encryption device die an inglorious death as industry or the public succeed in making them irrelevant, but others such as the Digital Millennium Copyright Act or DMCA live on for decades and present an ongoing malign influence. Most recently our ongoing coverage of dubious drone stories included a hefty dose of equally dubious action from lawmakers.

When considering these pieces of legislation it’s easy to characterise the politicians who advance them as gullible idiots easily swayed by any commercial lobbyist with a fistful of cash. But the reality is far more nuanced, while some of them may well be tempted by those lobbyists they are in most cases neither gullible nor foolish. Instead they are better characterised as clueless on technical issues, and thus easily swayed by received opinion rather than by technological reality. If there’s a fault in the system it’s that the essential feedback which provides the checks and balances is missing, and oddly while sitting here writing this story, the responsibility for this comes close to home. The solution doesn’t lie in changing the politicians, but in changing how they are treated by journalists. Continue reading “The Case For A Technology Aware Lobby Correspondent” →

A Look At All The Badge Hacks Of Supercon 2023

November 15, 2023 by Tom Nardi 6 Comments

For those of you who’ve had the opportunity to join us in Pasadena for Supercon, you’ll know it’s a wild ride from start to finish. Singling out a single moment as our favorite is pretty much impossible, but certainly the Sunday Badge Hacking Ceremony has to rank up there. It’s the culmination of ~78 hours of intense hardware and software hacking, and that’s not even counting the pre-show work that attendees often put into their creations. Every year, without fail, this community manages to pull off badge hacks that are beyond anything we could have imagined — and we’re the ones who made the thing in the first place.

Unfortunately, in the mad rush, we’ve never had a chance to actually photograph the hacked badges and share them with the Hackaday readers. This year, at the urging of some of the badge hackers themselves, we were able to throw together a suitable overhead light at the last minute and actually snapped shots of each badge after it was presented to the audience.

The resulting images, sorted by badge hacking category, are below. While some proved difficult to photograph, especially with an impromptu setup, we’re happy to at least have a complete record of this year’s creations. Hopefully we’ll be able to improve on our technique for 2024 and beyond. If yours shows up, or if you’d like to share your appreciation, sound off in the comments below!

Detecting Neutrinos, The Slippery Ghost Particles That Don’t Want To Interact

November 14, 2023 by Zoe Skyforest 62 Comments

Neutrinos are some of the most elusive particles that are well-known to science. These tiny subatomic particles have no electric charge and an extremely small mass, making them incredibly difficult to detect. They are produced in abundance by the sun, as well as by nuclear reactions on Earth and in supernovae. Despite their elusive nature, scientists are keen to detect neutrinos as they can provide valuable information about the processes that produce them.

Neutrinos interact with matter so rarely that it takes a very special kind of detector to catch them in the act. These detectors come in a few different flavors, each employing its unique method to spot these elusive particles. In this article, we’ll take a closer look at how these detectors work and some of the most notable examples of neutrino detectors in the world today.

Vectorscope KiCad Redrawing Project

November 13, 2023 by Chris Lott 23 Comments

When I saw this year’s Supercon Vectorscope badge, I decided that I had to build one for myself. Since I couldn’t attend in-person, I immediately got the PCBs and parts on order. Noting that the GitHub repository only had the KiCad PCB file and not the associated schematics and project file, I assumed this was because everyone was in a rush during the days leading up to Supercon weekend. I later learned, however, that there really wasn’t a KiCad project — the original design was done in Circuit Maker and the PCB was converted into KiCad. I thought, “how hard can this be?” and decided to try my hand at completing the KiCad project.

Fortunately I didn’t have to start from scratch. The PCB schematics were provided, although only as image files. They are nicely laid out and fortunately don’t suffer the scourge of many schematics these days — “visual net lists” that are neither good schematics nor useful net lists. To the contrary, these schematics, while having a slightly unorthodox top to bottom flow, are an example of good schematic design. Continue reading “Vectorscope KiCad Redrawing Project” →

JawnCon 0x0: A Strong Start With A Bright Future

November 13, 2023 by Tom Nardi 9 Comments

Last month, I had the pleasure witnessing a birth. No, not of a child. What I’m talking about is something far rarer, though arguably, just as loud and danger fraught — the birth of a new hacker convention.

The very first JawnCon took place on October 19th and 20th at Arcadia University, just outside of Philadelphia. If you’re in the Northeast US and suddenly find yourself surprised to learn that a hacker con managed to slip under your radar, don’t be. The organizers, who previously helped launch the WOPR Summit back in 2019, wisely decided to keep the scale of this first outing in check. Just a single track of talks, a chill out room, and 130 or like-minded individuals.

Although, even if they’d hatched a more ambitious plan, it’s hard to imagine they’d have had enough time to pull it off. Due to various circumstances, JawnCon had to come together at a breakneck pace, with less than 100 days separating the con’s inception and kickoff. That an event such as this could not only be organized so quickly, but go off without a hitch, is a testament to the incredible folks behind the scenes.

As for what a Jawn is…well, that might take a bit more explaining. It’s regional slang that’s perhaps best described as a universal noun in that it can be used to refer to basically anything or anyone. Think “smurf” or “da kine”. According to organizer Russell Handorf, the all-encompassing nature of the word describes not only his personal ethos but the spirit of the event. Rather than focusing too closely on any one aspect of hacking, JawnCon set out to explore a diverse array of tech topics from both the new and old schools. It would be an event where you could listen to a talk on payphone remote management, try your hand at lock picking, and learn about the latest in anti-drone technology, all under the same roof.

To that end, the team did an incredible job. Everyone I spoke to, young or old, newbie or vet, had a fantastic time. What’s more, as revealed in the Closing Remarks, the con actually managed to stay in the black — no mean feat for a first attempt. With a little luck, it seems like JawnCon is well on its way to becoming one of the Northeast’s can’t-miss hacker events. Continue reading “JawnCon 0x0: A Strong Start With A Bright Future” →

Hackaday Links: November 12, 2023

November 12, 2023 by Dan Maloney 11 Comments

Somebody must really have it in for Cruise, because the bad press just keeps piling up for the robo-taxi company. We’ve highlighted many of the company’s woes in this space, from unscheduled rendezvous with various vehicles to random acts of vandalism and stupid AI pranks. The hits kept coming as California regulators pulled the plug on testing, which finally convinced parent company General Motors to put a halt to the whole Cruise testing program nationwide. You’d think that would be enough, but no — now we learn that Cruise cars had a problem recognizing children, to the point that there was concern that one of their autonomous cars could clobber a kid under the right conditions. The fact that they apparently knew this and kept sending cars out for IRL testing is a pretty bad look, to say the least. Sadly but predictably, Cruise has announced layoffs, starting with the employees who supported the now-mothballed robo-taxi fleet, including those who had the unenviable job of cleaning the cars after, err, being enjoyed by customers. It seems a bit wrongheaded to sack people who had no hand in engineering the cars, but then again, there seems to be a lot of wrongheadedness to go around.

Supercon And Soylent Green

November 11, 2023 by Elliot Williams 10 Comments

The 2023 Hackaday Supercon is all done and dusted, and we’re still catching up on our sleep. I couldn’t ask everyone, but a great time was had by everyone I talked to. It’s honestly a very special crowd that shows up in Pasadena every November, and it’s really the attendees who make it what it is. We just provide the platform to watch you shine. Thank you all!

It all started out on Friday with an open day of chilling out and badge experimentation. Well, chill for those of you who didn’t have a bug in their badge code, anyway. But thanks to some very keen observation and fantastic bug reports by attendees, Al and I figured out what we’d done and pushed a fix out to all 300 of the badges that were given out on the first day. And thanks to the remaining 200 folks who walked in the next day, who fixed their own badges at Tom’s Flashing Station.

From then on, it was one great talk after another, punctuated by badge hacks and all the other crazy stuff that people brought along with them to show off. For me, one of the highlights was on Sunday morning, as the Lightning Talks gave people who were there a chance to get up and talk about whatever for seven minutes. And subjects ranged from a mad explosive propane balloon party, to Scotty Allen’s experience with a bad concussion and how he recovered, to a deep dive into the world of LED strands and soft sculptures from our go-to guru of blinkiness, Debra [Geek Mom] Ansell.

Supercon first-timer Katie [Smalls] Connell gave a phenomenal talk about her wearable LED art things, Spritelights. These are far from simple art pieces, being a combination of medical adhesive, home-mixed Galinstan – a metal alloy that stays flexible at human body temperature, and soon even flexible printed batteries. That this whole project hit us without warning from out of the audience just made it more impressive.

And these were just the folks who stepped up on stage. The true story of Supercon also belongs to all the smaller conversations and personal demos taking place in the alley or by the coffee stand. Who knows how many great ideas were hatched, or at least seeds planted?

So as always, thank you all for coming and bringing your passions along with. Just like Soylent Green, Supercon is made of people, and it wouldn’t be half as yummy without you. See you all next year. And if you’re thinking of joining us, get your tickets early and/or submit a talk proposal when the time comes around. You won’t meet a more warm and welcoming bunch of nerds anywhere.
