Pretty much every modern car has some driver assistance feature, such as lane departure and blind-spot warnings, or adaptive cruise control. They’re all pretty cool, and they all depend on …read more

If you are younger than a certain age, RLL probably doesn’t mean much to you. Old consumer-grade hard drives used MFM (modified frequency modulation like a floppy disk uses) and …read more

The Xbox 360 was a difficult console to jailbreak. Microsoft didn’t want anyone running unsigned code, and darn if they didn’t make it difficult to do so. However, some nifty …read more

Well, that was “fun”. Last week, we wrote a newsletter post about the state of Hackaday’s comments. We get good ones and bad ones, and almost all the time, we …read more

This week on the Podcast, Hackaday’s Elliot Williams and Kristina Panos joined forces to bring you the latest news, mystery sound, and of course, a big bunch of hacks from …read more

The double-slit experiment, first performed by [Thomas Young] in 1801 provided the first definitive proof of the dual wave-particle nature of photons. A similar experiment can be performed that shows …read more

Depending on who you ask, the big news this week is that quantum computing researchers out of China have broken RSA. (Here’s the PDF of their paper.) And that’s true… …read more

These days, when something electronic breaks, most folks just throw it away and get a new one. But as hackers, we prefer to find out what the actual problem is …read more

Some inventions are so simple that it’s hard to improve them. The magnetic compass is a great example — a magnetized needle, a bit of cork, and a bowl of …read more

Ah, the Sinclair ZX Spectrum. A popular computer in Britain and beyond, but now rather thin on the ground. If you can’t find one, fear not, for now—you can apparently …read more
