Over on YouTube [Drake] from the [styropyro] channel investigates what happens when you take an enormous tungsten incandescent light bulb and pump 30,000 watts through it. The answer: it burns bright enough to light up the forest at night, and hot enough to cook food and melt metal. And why on Earth would anybody do […]
Ever heard of MUMPS? Both programming language and database, it was developed in the 1960s for the Massachusetts General Hospital. The goal was to streamline the increasingly enormous timesink that information and records management had become, a problem that was certain to grow unless something was done. Far from being some historical footnote, MUMPS (Massachusetts […]
If you exclude certain companies like Peloton, the world of cycling technology is surprisingly open. It’s not perfect by any means, but there are enough open or open-ish standards for many different pieces of technology from different brands to interoperate with each other, from sensors and bike computers and even indoor trainers to some extent. […]
Back during WWII, Chrysler bodged five inline-6 engines together to create the powerful A57 multibank tank engine. [Maisteer] has some high-revving inline-4 motorcycle engines he’s trying to put together too, but unlike 1940s Chrysler, he also has a trombone… and a lot more RPMs to deal with. The Chrysler flatheads were revving at a few […]
This week Jonathan chats with Konstantinos Margaritis about SIMD programming. Why do these wide data instructions matter? What’s the state of Hyperscan, the project from Intel to power regex with SIMD? And what is Konstantinos’ connection to ARM’s SIMD approach? Watch to find out!

Color 3D printing has gone mainstream, and we expect more than one hacker will be unpacking one over the holidays. If you have, say, a color inkjet printer, the process is simple: print. Sure, maybe make sure you tick the “color” box, but that’s about it. However, 3D printers are a bit more complicated. There […]
An unlikely hit of the last few months’ consumer hardware has been a power bank branded by the German confectionery company Haribo. It first gained attention in backpacking circles because of its high capacity for a reasonable weight, and since then has been selling like the proverbial hot cakes. Now Amazon have withdrawn it from […]
Ever wonder what happens to those digital price tags you see in stores once they run out of juice? In what is a prime example of e-waste, many of those digital price tags are made with non-replaceable batteries, so once their life is over they are discarded. Seeing an opportunity to breathe new life into […]
One easy way to make a very accurate clock is with a WiFi-enabled microcontroller like an ESP32 and a display: set up NTP, and you’ll never be off by more than a minute. This water clock project by [Liebregts] is not like that — there are no electronics to speak of, and if the clock […]
