You’d think a paper from a science team from Carnegie Mellon would be short on fun. But the team behind LegoGPT would prove you wrong. The system allows you to enter prompt text and produce p…

It was such an innocent purchase, a slightly grubby and scuffed grey plastic box with the word “P O L A R O I D” intriguingly printed along its top edge. For a little more than a tenner…

Launching rockets into the sky can be a thrill, but why not make the fall just as interesting? That is exactly what [I Build Stuff] thought when attempting to build a self-landing payload. The idea…

Last time we talked about how the original PC has a limit of 640 kB for your programs and 1 MB in total. But of course those restrictions chafed. People demanded more memory, and there were workaro…

Metalized Mylar “space blankets” are sold as a survivalist’s accessory, primarily due to their propensity for reflecting heat. They’re pretty cheap, and [HamJazz] has perfor…

Once a printed circuit board (PCB) has been assembled it’s rather hard to look inside of it, which can be problematic when you have e.g. a multilayer PCB of an (old) system that you really wo…

The drivetrain of most modern bicycles has remained relatively unchanged for nearly a century. There have been marginal upgrades here and there like electronic shifting but you’ll still mostl…

As with all aging bodies, clogged tubes form an increasing issue. So too with the 47-year old Voyager 1 spacecraft and its hydrazine thrusters. Over the decades silicon dioxide from an aging rubber…

When you think of Singer, you usually think of sewing machines, although if you are a history buff, you might remember they diversified into calculators, flight simulation, and a few other odd busi…

Today in the it’s-surprising-that-it-works department we have a ding dong doorbell extension from [Ajoy Raman]. What [Ajoy] wanted to do was to extend the range of his existing doorbell so th…

If you want to convert heat into electrical power, it’s hard to find a simpler method than a thermoelectric generator. The Seebeck effect means that the junction of two dissimilar conductors will p…

Spectre lives. We’ve got two separate pieces of research, each finding new processor primitives that allow Spectre-style memory leaks. Before we dive into the details of the new techniques, l…

Intuitively, you think that everything that you stretch will pull back, but you wouldn’t expect a couple of pieces of plastic to win. Yet, researchers over at [AMOLF] have figured out a way to make…

Join Hackaday Editors Elliot Williams and Tom Nardi as they take a whirlwind tour of the best and brightest hacks of the last week. This episode starts off with an update about that Soviet Venus la…

For a while now part of my email signature has been a quote from a Hackaday commenter insinuating that an article I wrote was created by a “Dumb AI”. You have my sincerest promise that …

Remember The Clapper? It was a home automation tool (of sorts) that let you turn appliances on and off by clapping. [Kevin O’Connor] has built something rather similar, if more terrifying. It…

The Mac mini is the closest to an Apple-based SBC you can get, so it lends itself to unusual portable computers. [Scott Yu-Jan] is back to tackle a portable build using the latest and greatest M4 m…

Recently in material science news from China we hear that [Hailin Peng] and his team at Peking University just made the world’s fastest transistor and it’s not made of silicon. Before w…

We love clocks, but we especially love unusual timepieces that aren’t just about showing the hour of the day. [Simone Giertz] built a flip clock moon phase tracker for a friend. While in Egyp…

There’s just some joy in an instant camera. They were never quality cameras, even in the glory days of Polaroid, but somehow the format has survived while the likes of Kodachrome have faded a…
