Ask Hackaday: Solutions, Or Distractions?

December 10, 2025 by 13 Comments

The “Long Dark” is upon us, at least for those who live north of the equator, and while it’s all pre-holiday bustle, pretty lights, and the magical first snow of the season now, soon the harsh reality of slushy feet, filthy cars, and not seeing the sun for weeks on end will set in. And when it does, it pays to have something to occupy idle mind and hands alike, a project that’s complicated enough to make completing even part of it feel like an accomplishment.

But this time of year, when daylight lasts barely as long as a good night’s sleep, you’ve got to pick your projects carefully, lest your winter project remain incomplete when the weather finally warms and thoughts turn to other matters. For me, at least, that means being realistic about inevitabilities such as competition from the day job, family stuff, and the dreaded “scope creep.”

It’s that last one that I’m particularly concerned with this year, because it has the greatest potential to delay this project into spring or even — forbid it! — summer. And that means I need to be on the ball about what the project actually is, and to avoid the temptation to fall into any rabbit holes that, while potentially interesting and perhaps even profitable, will only make it harder to get things done.

Hacking When It Counts: DIY Prosthetics And The Prison Camp Lathe

July 14, 2025 by 13 Comments

There are a lot of benefits to writing for Hackaday, but hands down one of the best is getting paid to fall down fascinating rabbit holes. These often — but not always — delightful journeys generally start with chance comments by readers, conversations with fellow writers, or just the random largesse of The Algorithm. Once steered in the right direction, a few mouse clicks are all it takes for the properly prepared mind to lose a few hours chasing down an interesting tale.

I’d like to say that’s exactly how this article came to be, but to be honest, I have no idea where I first heard about the prison camp lathe. I only know that I had a link to a PDF of an article written in 1949, and that was enough to get me going. It was probably a thread I shouldn’t have tugged on, but I’m glad I did because it unraveled into a story not only of mechanical engineering chops winning the day under difficult circumstances, but also of how ingenuity and determination can come together to make the unbearable a little less trying, and how social engineering is an important a skill if you want to survive the unsurvivable.

3D Print Yourself These Mini Workshop Tools

September 6, 2024 by 28 Comments

Kitting out a full workshop can be expensive, but if you’re only working on small things, it can also be overkill. Indeed, if your machining tends towards the miniature, consider building yourself a series of tiny machines like [KendinYap] did. In the video below, you can see the miniature electric sander, table saw, drill press, and cut-off saw put through their paces.

Just because the machines are small, doesn’t mean they’re not useful. In fact, they’re kind of great for doing smaller jobs without destroying what you’re working on. The tiny belt sander in particular appeals in this case, but the same applies to the drill press as well. [KendinYap] also shows off a tiny table and circular saw. The machines are straightforward in their design, relying largely on 3D printed components. They’re all powered by basic DC brushed motors which are enough to get the job done on the small scale.

They look particularly good if tiny scale model-making is your passion.
