Three Years In, JawnCon Continues To Grow And Impress

Make no mistake, just getting a hacker con off the ground is a considerable challenge. But the really hard part comes after. To be more than a one-off success story, you’ve got to expand the event year after year in a manageable way. Go too slow, and attendees might lose interest. Move too fast, and you run the risk of going broke if your ticket sales don’t keep up with your ambitions.

Luckily for hackers living in the Philadelphia area, the folks behind JawnCon have once again demonstrated they’re able to thread the needle. While the ticket price remained the same as in 2024, this year an additional track of talks was introduced as well as expanded activities throughout the con. Even though it only wrapped this past weekend, there’s already buzz about what the event will look like in 2026.

Until then, let’s take a look at some of the projects that were on display at this year’s JawnCon. If it’s the talks you’re after, they’ll be edited and uploaded to the event’s YouTube page in the near future. In the meantime, the Friday and Saturday live streams are still available.

2025 Hackaday Supercon: Crafting The Final Frontier Keynote Event

In the history of entertainment, few properties have made the sort of indelible mark on popular culture as Star Trek has. In 950 episodes across the twelve television series that have carried the name, the franchise has made a spectacle not of explosions and machismo, but of competent professionals working together to solve complex problems. In the world of Star Trek, the coolest people in the room are the scientists, engineers, physicists, and doctors — is it any wonder so many in the sciences credit the show for putting them on their career path?

Hardware hacker, maker, and Trekkie Andrew [MakeItHackin] will lead the panel.
To celebrate the impact of Star Trek, we’re proud to announce our keynote event for the 2025 Hackaday Supercon: Crafting the Final Frontier. This round-table discussion led by Andrew [MakeItHackin] will bring together some of the artists that have helped cultivate the look and feel of the final frontier since Star Trek: The Next Generation and all the way into the modern era with Star Trek: Picard.

While the art direction of the original Star Trek series from 1966 was remarkably ahead of its time, these are some of the key individuals who were brought in to refine those early rough-hewn ideas into cultural touchstones. Their work ended up becoming more than simple entertainment, and ultimately helped inspire some of the real-world technology we use on a daily basis. The iconic LCARS computer interface predicted the rise of the touch screen, while its impossible to look at props such as the PADD and Tricorder and not see the parallels with modern tablets and smartphones.

Meshtastic: A Tale Of Two Cities

If I’m honest with myself, I don’t really need access to an off-grid, fault-tolerant, mesh network like Meshtastic. The weather here in New Jersey isn’t quite so dynamic that there’s any great chance the local infrastructure will be knocked offline, and while I do value my privacy as much as any other self-respecting hacker, there’s nothing in my chats that’s sensitive enough that it needs to be done off the Internet.

But damn it, do I want it. The idea that everyday citizens of all walks of life are organizing and building out their own communications network with DIY hardware and open source software is incredibly exciting to me. It’s like the best parts of a cyberpunk novel, without all the cybernetic implants, pollution, and over-reaching megacorps. Well, we’ve got those last two, but you know what I mean.

Meshtastic maps are never exhaustive, but this gives an idea of node density in Philly versus surrounding area.

Even though I found the Meshtastic concept appealing, my seemingly infinite backlog of projects kept me from getting involved until relatively recently. It wasn’t until I got my hands on the Hacker Pager that my passing interest turned into a full blown obsession. But it’s perhaps not for the reason you might think. Traveling around to different East Coast events with the device in my bag, it would happily chirp away when within range of Philadelphia or New York, but then fall silent again once I got home. While I’d get the occasional notification of a nearby node, my area had nothing like the robust and active mesh networks found in those cities.

Well, they say you should be the change you want to see in the world, so I decided to do something about it. Obviously I wouldn’t be able to build up an entire network by myself, but I figured that if I started standing up some nodes, others might notice and follow suit. It was around this time that Seeed Studio introduced the SenseCAP Solar node, which looked like a good way to get started. So I bought two of them with the idea of putting one on my house and the other on my parent’s place down the shore.

The results weren’t quite what I expected, but it’s certainly been an interesting experience so far, and today I’m even more eager to build up the mesh than I was in the beginning.

Honoring The Legacy Of Robert Murray-Smith

We at Hackaday are deeply saddened to learn of the passing of Robert Murray-Smith. The prolific experimenter had spent over a decade on YouTube, creating more than 2,500 videos where he gleefully demonstrated his seemingly endless collection of homemade contraptions. At least eighteen of which ended up on the pages of Hackaday since we first crossed paths with him back in 2013.

Like many of you, we were also shocked to find that Robert made the decision to end his own life. As cliché as it might sound, he simply didn’t seem like the type. His demeanor was always boisterous in his videos, exhibiting an almost child-like joy as he showed off his latest creation with a laugh and smile.

But as explained by his brother Dave in the brief announcement video posted yesterday, his outward appearance was a well-rehearsed mask that covered a deepening depression. Regular viewers of Robert’s videos knew he lost his wife, as he shared a memorial video for her in April of 2024. What he was less open about with his viewers was his own health, which it turns out had been rapidly declining for the last few months.

We now know that simply getting up and walking around had become painful for Robert, a fact obscured by the fact that most of his videos saw him seated at his workbench or in the back garden. That he was able to continue making so many videos at all speaks not only to his passion for technology and engineering, but the great love he had for the community that he’d built.

From the video we also learned that Robert found it very difficult to discuss his declining mental and physical health with friends and family. For men of his generation, the “strong and silent type” was often the ideal. Given all that he was going through, nobody could fault him for experiencing a sense of hopelessness, and yet his brother explains that Robert would never admit to the difficulties he was facing. Whenever pushed to talk about his feelings, he’d respond with that phrase which we’ve all heard (and maybe used once or twice) — “I’m fine.”

Because of this, Robert’s family has partnered with the suicide prevention charity CALM (Campaign Against Living Miserably) to try and raise awareness about men’s mental health. They ask that anyone who wishes to honor Robert make a donation to CALM, in the hopes that they can help others who may find themselves in a similar situation.

It’s no great secret that many in the hacker and maker communities face their own daily struggles. Whether it’s from being neurodivergent, or the inability to fit in with mainstream society. Several of the staff here at Hackaday are from marginalized groups, and even among those who aren’t, let’s just say we have it on good authority that most of them didn’t get to sit with the “cool kids” back in high school. We also know that, just like Robert, many in the community find it difficult to communicate with others about how this impacts their mental health.

The lasting legacy of Robert Murray-Smith will of course be his incredible body of work, which will continue to inspire millions of viewers. But we can also honor him by making sure that we’re looking out for the well-being of friends, family, and even ourselves. There are resources available, and there’s no shame in asking for help when you need it.

JawnCon Returns This Weekend

For those local to the Philadelphia area, a “jawn” can be nearly anything or anyone — and at least for this weekend, it can even be a hacker con building up steam as it enters its third year. Kicking off this Friday at Arcadia University, JawnCon0x2 promises to be another can’t-miss event for anyone with a curious mind that lives within a reasonable distance of the Liberty Bell.

The slate of talks leans slightly towards the infosec crowd, but there’s really something for everyone on the schedule. Presentations such as Nothing is Safe: An Introduction to Hardware (In)Security and Making the GameTank – A New, Real 8-Bit Game Machine will certainly appeal to those of us who keep a hot soldering iron within arm’s reach, while Rolling Recon & Tire Prints: Perimeter Intrusion Detection and Remote Shenanigans via Rogue Tire Stem RF and Get More Radio Frequency Curious will certainly appeal to the radio enthusiasts.

A New Generation Of Spacecraft Head To The ISS

While many in the industry were at first skeptical of NASA’s goal to put resupply flights to the International Space Station in the hands of commercial operators, the results speak for themselves. Since 2012, the SpaceX Dragon family of spacecraft has been transporting crew and cargo from American soil to the orbiting laboratory, a capability that the space agency had lost with the retirement of the Space Shuttle. Putting these relatively routine missions in the hands of a commercial provider like SpaceX takes some of the logistical and financial burden off of NASA, allowing them to focus on more forward-looking projects.

But as the saying goes, you should never put all of your eggs in one basket. As successful as SpaceX has been, there’s always a chance that some issue could temporarily ground either the Falcon 9 or the Dragon.

While Russia’s Progress and Soyuz vehicles would still be available in an emergency situation, it’s in everyone’s best interest that there be multiple backup vehicles that can bring critical supplies to the Station.

Which is precisely why several new or upgraded spacecraft, designed specifically for performing resupply missions to the ISS and any potential commercial successor, are coming online over the next few years.

In fact, one of them is already flying its first mission, and will likely have arrived at the International Space Station by the time you read this article.
