Apple A4 chip dissected by Chipworks: Cortex A8 in package “sandwich”

iFixit's iPad teardown turned up the expected huge battery and dinky circuit boards, but of course our prime interest has been in the custom Apple A4 processor that keeps the iPad whipping along.  While we know it's ARM based, Apple have been unduly coy in spilling any other information about the 1GHz chipset; iFixit decided to send the die over to Chipworks, who specialise in taking a more forensic look at silicon.

Motorola DROID costs $187.75 to make, claims iSuppli

Chumby One teardown: yep, it’s very hackable

Barnes & Noble nook cracked open, rooted

Barnes & Noble nook cracked open, rooted

The lure of Android has brought hackers to the Barnes & Noble nook like piranhas to still-kicking meat, and it turns out there's plenty of intrigue inside the ebook reader.  Over at nookDevs they've not only stripped the device to its bare circuitboards, they've also managed to root it.

Points of note include Android seemingly being loaded onto a 2GB internal microSD card - potentially a cause of sluggish OS performance - and a Samsung S3C6410 processor that's actually capable of OpenGL ES 1.1/ 2.0 among other things.  The Android install itself, meanwhile, is a generic OS 1.5 build with some B&N customization on top

What should be interesting is how the nook gets hacked, especially given the interesting hardware.  The nookDevs contributors have already figured out a way to spoof the DNS and feed content to the nook as if it came from B&N.
