That said, the “blue” ones are a beautiful aquamarine (the aqua/white two-tone reminds me of a Nash Metropolitan… same color scheme ) ) and the metal parts are powdercoated.

It’s untraceable because the only label on it is the JLAudio logo (…?!) and a serial number or lot code.
Some (these –> ) have an untraceable 16-pin SOIC as their only chip. You can get a 2nd gen iPod Shuffle clone from eBay for a buck fitty (or less!) now… search for “mini clip mp3 player” ) Sure, you have to wait for it to come from HK, the /slow/ way (or fork over an extra $2 or so for ePacket, in which case it’s about two weeks), and it doesn’t have a shuffle mode or voiceover features, but if you’ve got a sixteen gig MicroSD card around you’ve got eight Shuffles’ worth of storage in one vaguely similar player.īeing the wacky sort of person I am, I buy those players, and I take them apart to see what makes ’em tick. For other things, it’s a more stark contrast even than that. (They might be right, too… ) )īy the way, the “one for the price of two” deal I mention above, really only applies to their computer hardware.

You get the same hardware for roughly half the cost if you’re willing to put up with Windows - or if you install a Linux distro on top, in which case you get the pretty looks as well. Posted in Mac Hacks, Teardown Tagged #buzzfeedHeadlineFTW, #courage, apple, charger, macbook, magjack Post navigationĪpple prices are always inflated… and have been for a very long time. The takeaway from these teardowns is that cheap chargers are a false economy, and you probably should pony up the cash for the real version. He’s done iPad chargers, iPhone chargers, and other small, square, white switching power supplies. This isn’t ’s first teardown of genuine and not Apple products. The fake charger doesn’t do this, and when you poke the connector with a paper clip, sparks fly. Until then, the Magsafe connector only outputs 0.6 Volts.

It’s this microcontroller that kept you safe that one time you decided to lick a Magsafe connector not allowing the full 20 Volts to go through until the connector has connected. The genuine charger does power factor correction, uses quality caps, has real isolation on the PCB, and uses a microcontroller that’s almost as powerful (and a direct architectural descendant) as the CPU in the original Macintosh. Like the cheap copy, it’s a switching power supply, but has a few features that make it much better.
The genuine MacBook charger is much more complicated.
This output is converted into DC with a few diodes, filtered, and wired into a MagSafe adapter. The mains power comes in, it’s chopped up into pulses, and these pulses are turned into a high-current, low-voltage output in a flyback transformer. In fact, it’s almost the simplest possible AC to DC converter. The fake ones will make sparks thanks to the cost-saving design, and shouldn’t be used by anyone.Ī genuine Apple MacBook charger is a phenomenal piece of engineering, but the fake one is not. has torn apart a number of these chargers, and his investigations allowed for an obvious pun in this post. When it comes to fake MacBook chargers, you can ask for a lot more. It’s not time for a eulogy quite yet, but needless to say, Apple hardware was great, and the charger was even better. Yesterday, Apple showed the world how courageous they are by abandoning their entire PC market.
