Metrology fans are usually at least a little bit in love with Mitutoyo, and rightfully so. The Japanese company has been making precision measuring instruments for the better part of 100 years, and users appreciate their precision almost as much as the silky smooth feel of their tools. If you can afford it, a Mitutoyo […]
We’ve said it before and we’ll say it again: water always finds a way in. That’s particularly problematic for things like wire splices in damp environments, something that no amount of electrical tape is going to help. Heat shrink tubing might be your friend here, but for an electrically isolated and mechanically supported repair, you […]
In this episode, the CrowdStrike fiasco has Hackaday Editors Elliot Williams and Tom Nardi pondering the fragility of our modern infrastructure. From there the discussion moves on to robotic sailboats, the evolving state of bespoke computers, and the unique capabilities of the Super Nintendo cartridge. You’ll also hear about cleaning paintings with lasers, the advantages […]
Sometimes off-the-shelf solutions to a problem don’t meet your expectations. That’s what led [TomGoff] to build his own solar pond fountain. This build features a lot of creative reuse of materials [TomGoff] already had on hand, like the end of a cable reel for the platform and a wheelbarrow inner tube for flotation. A 3D […]
It’s a bit of bitter irony, when a security product gets used maliciously, to pull off the exact attack it was designed to prevent. Enter Proofpoint, and the EchoSpoofing attack. Proofpoint offers an email security product, filtering spam and malicious incoming emails, and also handling SPF, DKIM, and DMARC headers on outgoing email. How does […]
Most people love lasers, because they can make cats chase, read music from a shiny disc, etch and cut materials, and be very shiny in Hollywood blockbusters, even when their presence makes zero sense. That said, lasers are also extremely dangerous, as their highly focused nature and wide range of power levels can leave a […]
Floppies were once the standard method of information exchange, but decades of storage can render them unreadable, especially if mold sets in. [Rob Smith] wanted to clean some floppies in style and made a Disco Rube Goldberg-Style device for the job. Starting with a disk caddy on linear rails, [Smith] has a track for the […]
Magnetic materials are typically divided into ferromagnetic and antiferromagnetic types, depending on their magnetic moments (electron spins), resulting in either macroscopic (net) magnetism or not. Altermagnetism is however a recently experimentally confirmed third type that as the name suggests alternates effectively between these two states, demonstrating a splitting of the spin energy levels (spin-split band […]
Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While quantum physics has been around for over a century, it can still be a bit tricky to wrap one’s head around since some of […]
