Ken Shirriff embarked upon a teardown of counterfeit Apple laptop chargers. On the outside, they're typo-free and very convincing. Inside, though, they're a dangerous mangle of cheap parts and inexplicably bad decisions.
The most important feature of a charger is the isolation between the potentially-dangerous AC input and the low-voltage output… The counterfeit MagSafe charger has a dangerously small distance between the low voltage side (top) and the high voltage side (bottom). This is why you shouldn't buy counterfeit chargers.
I'm puzzled as to why counterfeit chargers never manage to have sufficient clearance distances. They use simple, low-complexity circuits so the circuit board layout should be straightforward. Except in the smallest cube phone chargers, they aren't fighting for every millimeter of space. It shouldn't take much additional effort to make the boards safer.

There are many nondescript and mundane tools for data recovery, but the Spider Board is not one of them. It lives up to its name, with 25 leglike needles that, carefully placed on copper traces on a denuded card, suck the data out of them like fly juice. PC-3000 Flash Spider Board Adapter is a […]
Terence Eden found a turntable [Amazon] that cost only £30 (~$40): "I accidentally bought a load of vinyl records. So I decided to buy the cheapest, shittiest, turntable possible," he writes. For firty paands he even gets a USB port to rip the records directly to digital. Is it any good? Not really. It plays […]

Physics may have been that class you sleepwalked your way through in high school. But while it might have just slipped under your radar throughout your academic career, you probably shouldn't have given it such shallow attention. Sure, we could focus on the immediate pluses of a career as a physicist, like the more than […]
If you're out of work…well, first, you have our sympathies. Right now, about 31 million Americans are drawing some form of unemployment benefits, which makes competition for virtually any job savagely fierce. But since nobody wants to wallow in the miseries of unemployment, the only legitimate course left open is to scrap like crazy to […]
