Ask Hackaday: What’s Your Worst Repair Win?

January 9, 2023 by Dan Maloney 191 Comments

Like many of you, I’ve become the designated “fix-it” person for my family and friends. While it can be a lot of work — I just finished an oil change that required me to lay in a cold, wet driveway and I can’t mention in polite company the substances I was bathed in while fixing a clogged pipe last week — I generally relish my role. I enjoy solving problems, I love working with my hands and my head, and who doesn’t like saving money and time?

But for me, the best part of being the fix-it guy is the satisfaction that comes from doing something others can’t do. I find this especially true with automotive repairs, which conventional wisdom says is strictly the province of factory-trained experts. A little bit of a hero complex, perhaps? Absolutely! After all, I don’t get paid for my repairs, so I’ve got to get a little something for the effort.

This is why a recent pair of unrelated fixes left me feeling thoroughly unsatisfied. Neither of these jobs was a clear win, at least in terms of getting the rush of being able to do something that nobody else could. At best, these were qualified wins, which both still left me feeling a little defeated. And that got me thinking that I’m probably not the only one who has had marginal repair wins like these.

Hackaday Links: January 8, 2023

January 8, 2023 by Dan Maloney 12 Comments

Something odd is afoot in the mountains around Salt Lake City, Utah, at least according to local media reports of remote radio installations that have been popping up for at least the past year. The installations consist of a large-ish solar panel, a weatherproof box full of batteries — and presumably other electronics, including radios — and a mast bearing at least one antenna. Local officials aren’t quite sure who these remote setups belong to or what they’re intended to do, but the installations obviously represent a huge investment in resources.

The one featured in the story was located near the summit of Twin Peaks, which is about 11,000 feet (3,300 meters) in elevation, which with that much gear was probably a hell of a hike. Plus, the owner took great pains to make sure the site would withstand the weather, with antenna mast guy wires that must have required lugging a pretty big drill up with them. There aren’t any photos of the radios in the enclosure, but one photo shows a 900-MHz LORA antenna, while another shows what appears to be a panel antenna, perhaps pointing toward another site. So maybe a LORA mesh network? Some comments in the Twitter thread show most people are convinced this is a Helium crypto mining rig, but the Helium Explorer doesn’t show any hotspots listed in that area. Either way, the owners are out of luck, since their gear is being removed if it’s on public land.

The Surprisingly Simple Way To Steal Cryptocurrency

January 6, 2023 by Jenny List 78 Comments

In the news a few days ago, the revelation that Luke Dashjr, a core Bitcoin developer, had his wallet compromised, and lost 200 BTC. A small fortune, and something of a shock. I’m guessing that someone with that expertise would not have left his private key lying around, so as a cryptocurrency non-enthusiast I’m left curious as to how the attackers might have done it. So I phoned a few friends who do walk those paths for an explanation, and the result was a fascinating conversation or two. The most probable answer is still that someone broke into his computer and copied the keys — straight-up computer theft. But there’s another possible avenue that doesn’t involve stealing anything, and is surprisingly simple. Continue reading “The Surprisingly Simple Way To Steal Cryptocurrency” →

The Problem With Passwords

January 3, 2023 by Jenny List 129 Comments

By now it’s probable that most readers will have heard about LastPass’s “Security Incident“, in which users’ password vaults were lifted from their servers. We’re told that the vaults are encrypted such that they’re of little use to anyone without futuristic computing power and a lot of time, but the damage is still done and I for one am glad that I wasn’t a subscriber to their service. But perhaps the debacle serves a very good purpose for all of us, in that it affords a much-needed opportunity for a look at the way we do passwords. Continue reading “The Problem With Passwords” →

2022: As The Hardware World Turns

January 3, 2023 by Tom Nardi 30 Comments

Well folks, we made it through another one. While it would be a stretch to call 2022 a good year for those of us in the hacking and making community, the light at the end of the tunnel does seem decidedly brighter now than it did this time 365 days ago. It might even be safe to show some legitimate optimism for the year ahead, but then again I was counting on my Tesla stocks to be a long-term investment, so what the hell do I know about predicting the future.

Eh, my kids probably weren’t going to college anyway.

Thankfully hindsight always affords us a bit of wisdom, deservedly or otherwise. Now that 2022 is officially in the rearview mirror, it’s a good time to look back on the highs (and lows) of the last twelve months. Good or bad, these are the stories that will stick out in our collective minds when we think back on this period of our lives.

Oh sure, some might wish they could take the Men in Black route and forget these last few years ever happened, but it doesn’t work that way. In fact, given the tumultuous times we’re currently living in, it seems more likely than not that at some point we’ll find ourselves having to explain the whole thing to some future generation as they stare up at us wide-eyed around a roaring fire. Though with the way this timeline is going, the source of said fire might be the smoldering remains of an overturned urban assault robot that you just destroyed.

So while it’s still fresh in our minds, and before 2023 has a chance to impose any new disasters on us, let’s take a trip back through some of the biggest stories and themes of the last year.

In Praise Of “Just Because” Hacks

December 31, 2022 by Elliot Williams 25 Comments

Sometimes you pick a project because the world needs it to be done. Or maybe you or a friend need it. Or maybe you don’t really need it, but it fulfills a longstanding dream. In my mind, the last stop before you reach “why am I doing this” is the “just because” hack.

The ideal “just because” hack is limited in scope. You don’t want to spend years on a whimsical project, and because of this a “just because” hack isn’t usually motivating enough to keep you going that long anyway, except for the tenacious few. A “just because” doesn’t necessarily have to be an easy win, but it makes sense for you to see your way out before you get in too deep.

I’m not sure if it’s the Baader-Meinhof phenomenon or not, but in the last week or so in the Hackaday universe, a lot of people have been singing the praises of “just because” hacks. (Check out this one discussion, for instance.) Mostly, it’s a combination of them turning out better than initially thought, or it’s about the learning that came along for the ride. Of course, many of them spin off into longer, serious projects even if they didn’t start that way.

Not everything in life can be frivolous, of course. But that makes the “just because” hack that much sweeter, and you should try to make mental room for them if you can. When the stakes are low, creativity can be high. You might still want to impose a deadline, lest you fall into eternal yak shaving, but take it easy. You don’t need a justification all the time: the journey can be the destination.

Hackaday Podcast 199: Ferrofluid Follies, Decentralized Chaos, And NTSC For You And Me

December 30, 2022 by Kristina Panos 5 Comments

This week, Editor-in-Chief Elliot Williams and Assignments Editor Kristina Panos decided against using one of Kristina’s tin can microphones to record the podcast, though that might be a cool optional thing to do once (and then probably never again).

After a brief foray into the news that the Chaos Communications Congress will be decentralized once again this year, as COVID restrictions make planning this huge event a complete headache (among other notable symptoms), we discuss the news that the EU is demanding replaceable batteries in phones going forward.

After that, it’s time for another What’s That Sound results show, and despite repeated listens, Kristina fails to guess the thing. Even if she’d had an inkling as to what it was, she probably would have said ‘split-flap display’ instead of the proper answer, which is ‘flip-dot display’, as a few people responded. Finally, it’s on to the hacks, where we talk about uses for ferrofluid and decide that it’s one of those things that’s just for fun and should not be applied to the world as some sort of all-purpose whacking device.

Check out the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!
