Kill A Watt Teardown

killawatt

Come on, folks. If we keep tearing apart everything that’s handed to us, we’ll never get nice things. SparkFun got their mitts on two Kill A Watts and proceeded to plug them into everything and then dismantled them to see how they work. The Kill A Watt keeps track of how much power is used over time. The largest load they found was their soda machine using 500W (should probably add a motion sensor to that). They plugged a meter on either side of a UPS and found out that it uses 5W just to charge. On the inside of the meter, there isn’t anything too substantial. One unlabeled IC runs the whole show.

Nintendo DSi Teardown

dsi_teardown

[bunnie] managed to pick up a Nintendo DSi while in Japan. It seems he had the device running less than an hour before he tore it down for an impromptu hotel photoshoot. There’s nothing too surprising and he mentions that the CPU certainly feels more capable than the previous model, which may explain the shorter battery life. The ARM processor sits under an RF shield directly below the WiFi card. The best photo is the top side of the board with every single debug point labeled in plain English on the silkscreen. We’re sure that’ll help with the development of new homebrew hardware.

[bunnie] has posted some interesting teardowns in the past. Have a look at his Sony XEL-1 teardown to see the inner workings of an OLED TV.

Xbox 360 Battery Pack Teardown

Reader, [Fox9p3400], opened up an Xbox 360 controller battery pack so we could all see what goes into one. It contains two Sanyo 2100mAh NiMH AA rechargeables (Model HR-3U 1.2V). In addition to that, there is an Atmel microcontroller (not pictured) and the copper temperature probe you can see above. He has more pictures on Photobucket.

OCZ Neural Impulse Actuator Teardown

m8ta fun did an extensive teardown of OCZ’s Neural Impulse Actuator (NIA). OCZ’s computer/mind interface is actually a fairly straight forward design. An analog front-end cleans and amplifies the ‘neural’ signal with a few op-amps before feeding it to a 24 bit analog to digital converter (ADC). A USB enabled PIC microcontroller reads the 24bit parallel ADC output through a common 7400 series parallel to serial adapter IC. The device has an ICSP programing header (top right), though it’s not yet clear if the PIC can be read or written.

Peek Email Reader Teardown

[morcheeba], who you should remember from CVS camera hacking, picked up a Peek and took some pictures while tearing it down. The Peek is a $100 QWERTY device with a simple OS designed only to check email. The device is being sold by T-Mobile with a $19.95/mo data plan. There’s nothing too spectacular to see other than 16MB of flash memory and a TI OMAP processor.

IPhone 3G: Under The Hood


TechOnline has cracked open the iPhone 3G to find out what makes it tick. They’ve released detailed diagrams as well as some videos of the dissection.

Calling this an incremental update, they note that the changes seem to be additions and improvements rather than a total rebuild of the original platform. They get into the nitty gritty, discussing not only the layout and structure, but even the importance of each chip manufacturer.

Some of the improvements are obvious, like 3G. Others include the battery not being permanently attached, and the headphone jack being flush mounted. Most of the changes were in who manufactured each chip.

IPhone: 2.0 Firmware Jailbroken, 3G Taken Apart


Oh, iPhone Dev Team, you are a hoot. It isn’t that you managed to jailbreak the iPhone 2.0 firmware on the day of its release, although we can’t help but smirk at that. It isn’t even that you revealed your handiwork in a playful way. We simply love that you expertly work us into a frenzy for the new jailbreak installer with few casual images and some aloof words. Now give us the installer before we get too antsy, please.

Not to be outshined, though, iFixit has posted a full iPhone 3G teardown, stripping away the sleek casing to feast on the goodness inside. They found some interesting changes from the last model: the glass screen, for example, is no longer glued to the LCD, which will no doubt make repairs less expensive. The battery is also unsoldered, meaning you won’t have to send the phone in for repair if the only battery needs maintenance.
