Thermoforming is the process of softening a material enough so that it can be tweaked into a new shape, with the source of the thermal energy being not particularly relevant. Correspondingly, after [Zion Brock]’s recent video on his journey into thermoforming PLA with a mold and a heat gun, he got many comments suggesting that […]
The media is full of breathless reports that AI can now code and human programmers are going to be put out to pasture. We aren’t convinced. In fact, we think the “AI revolution” is just a natural evolution that we’ve seen before. Consider, for example, radios. Early on, if you wanted to have a radio, […]
Getting PCBs made is often the key step in taking a dodgy lab experiment and turning it into a functional piece of equipment. However, it can be tedious to wait for PCBs to ship, and that can really slow down the iterative development process. If you’ve got a 3D printer, though, there’s a neat way […]
Are you ready to feel old? Lemmings just turned thirty-five. The famous puzzle game first came out in February of 1991 for the Commodore Amiga, before eventually being ported to just about everything else out there, from the ZX Spectrum to the FM Towns, and other systems so obscure they don’t have the class to start with […]
A lot of hacks get inspired by science fiction. When that inspiration is taken from the boob tube or the silver screen, the visual design is largely taken care of by the prop department. If, on the other hand, one seeks inspiration from the written word– like [Math Campbell] did for his smart pocket watch […]
Typically, when we want to take images, we use an image sensor paired with some sort of lens assembly to make a picture that’s sharply in focus. However, [okooptics] is here to show us there’s another way—using Scotch tape in place of a typical lens element. If you just put Scotch tape over an image […]
[James]’ Mechanical Organ of Dutch origin has been around longer than he has, but thanks to being rebuilt over the years and lovingly cared for, it delivers its unique performances just as well as it did back in the day. Even better, we’re treated to a good look at how it works. The organ produces […]
Keeping an eye on remaining battery charge. (credit: Luke Maximo Bell, YouTube) Although not a typical focus of people who fly quadcopter drones for a hobby or living, endurance flying has a certain appeal to it for the challenge it offers. Thus, as part of his efforts to collect all the world records pertaining to […]
Here’s the Hackaday Europe 2026 announcement that you’ve all been waiting for. But wait! This year there’s a twist, or rather two. What absolutely hasn’t changed, though, is that we’d love to see you there, and we’d love to hear about what you’ve been up to, so get your talk or workshop proposal in before […]
Ever wanted to know how engineers made their calculations before digital calculators were on every workbench? [Richard Carpenter] and [Robert Wolf] have just the thing—a sliderule simulator that can teach you how to do a whole bunch of complex calculations the old fashioned way! The simulator is a digital recreation of the Hemmi/Post 1460 Versalog […]
