Doom On A Picture Key Chain

[vimeo http://vimeo.com/6878807%5D

Alright, so Doom isn’t actually running on the key chain itself, but rather a BifferBoard: a small 150MHz x86 containing ethernet, serial, and even USB with only one watt of power consumption! The project is to show how easy it is to program the BifferBoard and getting it talking to other hackable items – such as the picture key chain for a display. Doom does appear a bit slow, but [Biff] figures its do to how haphazardly it grabs keyboard input over SSH.

PSP Go Gets Butchered (teardown)

Dx1CSXo13YF3NYBa

Not due to be released until the beginning of October, a PSP Go demo unit (shipped to G4TV) has already earned itself a teardown from [iFixit]. Among what was discovered:

– Once a few screws are removed, the battery is user replaceable (as-in: no soldering iron required)

– Wireless connectivity is only supplied through a 802.11b chip (no update to ‘n’, or even ‘g’, by Sony)

– Almost all chips are EMI-shielded (making them a bit more annoying to get to)

With a cheaper version of the PS3 ready to hit shelves, one can only wonder whether the relatively high price tag on this new PSP is worth it.

Update: It seems as though no party involved wanted the info leaked this early, which explains why the video and picture gallaries (up courtesy of Google) have been removed.

Update 2: The article (linked above) and video are now available. An explanation on why Sony had them remove the items for quite some time (plus some repair manuals) was posted by iFixit.

Gameboy Color Boot ROM

top_view_full

It’s only been a week since the Super Gameboy’s boot ROM was dumped by [Costis] and he’s already at it again. This time he’s managed to grab the Gameboy Color’s boot ROM. He found the newer Gameboy Color’s hardware is able to cope with a clock speed up to 100MHz, so the original clock increase trick he used on the Super Gameboy wouldn’t work again.

Instead he discovered a quick disconnection of clock and power before 0xFF50 would make the Gameboy jump to a random area within the ROM. Then it was only a matter of entropy, luck, and some special NOP instructions until eventually he had the boot ROM. Keep up the good work [Costis].

With Zipit, Who Needs A Netbook?

[Hunter Davis] keeps rolling out the hacks for the Zipit. In the past he showed us how to run DOSbox, and then how to get NES emulation working on this tiny device. Now he’s got Linux kernel 2.6.29 running Fluxbox with mouse (newly added), audio, and WiFi functionality. Follow his step-by-step flashing instructions to load the kernel into the Zipit. Once flashed, a partitioned microSD card servers as the filesystem and swap.

Who needs a 10.1 inch screen or an Atom processor when you can get this 2.8″ QVGA beauty with an XScale processor for around $40?

[Thanks Matt]

Vintage Hack – Game Boy Camera

Screenshot

Back in 2005, a member of a French robotics team named [Laurent] wrote a wonderful how-to that we somehow missed on using the Game Boy Camera as a vision device for a robot. The images above are actual shots from his project. The Game Boy Camera features a stunning 128×123 pixel resolution in a gorgeous 4 color gray-scale palette. Possibly the most attractive feature of this hack is that it is still possible to get a hold of these cameras for under ten dollars on ebay.

He connected the camera sensor to an Atmel AT90S4433 using a combination of digital and analog signals, and then used the microcontroller to echo the data back to his PC. His write up includes schematics for wiring up the sensor/microcontroller, the datasheet for the sensor, his C code for the whole project, and an easy to read pin out of the GBC connector. Although his project simply offloaded the image to a computer, it would be entirely possible to have the microcontroller respond to the image or simply just log and store it. It would also be just as easy to replace his Atmel chip with your own favorite microcontroller, as long as it has a couple Digital I/O ports and at least one Analog port (or an external analog to digital converter).

UPDATE: Good catch r4v5, it would require an ADC, not a DAC.

MP3 Hand Grenade

One man’s useless machine is another man’s treasure… or something. [Matt] shared a link to his MP3 gr3nade in the comments of our useless machines post. The project took a decomissioned hand grenade and shoehorned an MP3 player into it. His decision to locate the headphone jack where the safety pin goes is a nice touch.

This reminds us of the boss from a previous job who had a chrome plated hand grenade on his desk.  Now that was a useless object (and a useless boss). This project actually does something, but are you really going to ride around on the subway rockin’ out to the Bee Gees while holding a hand grenade?

Zune HD Teardown

dfkaj

Our friends over at ifixit are at it again, how they get these devices so early before release and make a complete teardown in time still amazes us. Today they bring us the latest Microsoft media device, the Zune HD. Some features worth mentioning: The astoundingly thin, 1mm we’re talking, OLED screen. The Nvidia Tegra 2600 processor, hinting at 3D game capability. And finally who could forget the 660 mAh battery. But isn’t that 129 mAh less than the iPod touch? Microsoft’s reply, supposedly the Zune HD is using many more low power hardware solutions in this device. Either way, the competition is on, who will be the victor?
