In a saga that brings to mind the hype and incidents with ReiserFS, [SavvyNik] takes us through the latest data corruption bug report and developer updates regarding the BcacheFS filesystem in the Linux kernel. Based on the bcache (block cache) cache mechanism in the Linux kernel, its author...

You might wonder why you’d repair a calculator when you can pick up a new one for a buck. [Tech Tangents] though has some old Sony calculators that used Nixie tubes, including one from the 1960s. Two of his recent finds of Sony SOBAX calculators need repair, and we think you’ll agree that...

When it comes to hacks, the best ones go to extremes. Either beautiful in their simplicity, or magnificent in their excess. And, well, today’s hack is the latter: excessive. [HTX Studio] built an assembly line for origami pigeons! One can imagine the planning process went something like this...

You probably do not need us to tell you that Arsenic is not healthy stuff. This wasn’t always such common knowledge, as for a time in the 19th century a chemical variously known as Paris or Emerald Green, but known to chemists as copper(II) acetoarsenite was a very popular green pigment. While...

The Functionalist design philosophy that Dieter Rams brought to Braun from the 50s to the 90s still inspires the look of a few devices, including Apple’s iPod, Teenage Engineer’s synthesizers and recorders – and [2dom]’s IR7 streaming radio. The streaming radio was inspired by Braun’s portable...

If you’re into automotive hacks and don’t watch [Robot Cantina], you are missing out. This hack has [Jimbo] taking a break from automotive hacking to butcher a poor, innocent Tecumseh lawnmower to run diesel fuel (or anything else) by converting the motor into a hot bulb engine. (Video embedded...

One of the difficult things about raising chickens is that you aren’t the only thing that finds them tasty. Foxes, raccoons, hawks — if it can eat meat, it probably wants a bite of your flock. [donutsorelse] wanted to protect his flock and to be able to know when predators were about without...

Today, we think nothing of sticking thousands of pages of documents on a tiny SD card, or just pushing it out to some cloud service. But for decades, this wasn’t possible. Yet companies still generated huge piles of paper. What could be done? The short answer is: microfilm. However, the long...

PLA is probably the most-printed filament on the market these days, and is there any wonder? It’s cheap, it’s easy, and it doesn’t poison you (as quickly as its competitors, anyway). What it doesn’t do very well is take the heat. Polymaker’s new HT-PLA formulation promises to solve that, and [My...

Recently, butlers to orange-colored cats got a bit of a shock when reading the news, as headlines began to call out their fuzzy feline friends as ‘freaks of nature’ and using similarly uncouth terms. Despite the name-calling, the actual reason for this flurry of feline fascination was more...

In what could be a big step forward for consumer rights, the Texas Senate recently unanimously voted to pass HB 2963, which references the “Diagnosis, maintenance, and repair of certain digital electronic equipment”. If signed by the governor, this would make Texas the ninth US state to enact...

A new console challenger has appeared, and it goes by the name Nintendo Switch 2. The company’s latest iteration of the home console portable hybrid initially showed promise by featuring a large 1080p display, though very little official footage of the handheld existed prior to the device’s...

We aren’t sure if [Joshua Bellamy] is serious that he wants a laminar flow to water his plants, but there are many places where having a smooth and predictable flow of water is useful or even essential. With his 3D printed adapter, you can produce laminar flow from any garden hose. If you...

Some people hate cables with a passion; others are agnostic and prefer cabled peripherals to having to stop and charge their mouse. [Matt] from DIYPerks has the best of both worlds with this wireless-powered, no-cable desk setup. The secret is embedded within the plywood desk: an evaluation kit...

When purchasing high-end gear, it’s not uncommon for manufacturers to include a little swag in the box. It makes the customer feel a bit better about the amount of money that just left their wallet, and it’s a great way for the manufacturer to build some brand loyalty and perhaps even get their...

Inspired by a gag from a mid-90s sitcom Father Ted, [Stephen] decided to create his own talking tape dispenser. This project is a actually a follow-up to the first version of the dispenser he built back in 2022, and [Stephen] has documented the process thoroughly for anyone wanting to build...

Saleae logic analyzers seem to have it all: good sampling rates, convenient protocol decoding, and plenty of channels – but not a good way to set rising or falling-edge triggering. [James] found this rather inconvenient when debugging embedded devices, and shared a workaround that replicates...

Regular ding-dong doorbells are fun and all, but it can be nice to put something a little more special by your front door. To that end, [Arpan Mondal] built this neat little piano doorbell to make visiting his home just a touch more fun. The heart of the build is an ESP32 microcontroller. It’s...

Over on his secondary YouTube channel, [Jeff Geerling] recently demoed the new Mitxela Precision Clock Mk IV. This clock uses GPS to get the current time, but also your location so it can figure out what time zone you’re in and which daylight savings time might apply. On the back a blinking...

You can get just about any gear reduction you want using conventional gears. But when you need to get a certain reduction in a very small space with minimal to no backlash, you might find a wave drive very useful. [Mishin Machine] shows us how to build one with (mostly) 3D printed components...
