Deadly Computer Blog
So, this is something mike has been looking to make for the past few days, ever since he got his new computer case for his awesome new computer. He originally wanted to buy a server rack, so he can mount his case in it, and mount the NAS he has with it, but those cost lots of lots of money. So, our solution, after thinking up at night, was to make one ourselves. I suggested iron gas piping, and mike suggested angle iron. Mike won because in the end, it would be easier to build with angle iron.
5 Reasons We May Live in a Multiverse
The universe we live in may not be the only one out there. In fact, our universe could be just one of an infinite number of universes making up a "multiverse." Though the concept may stretch credulity, there's good physics behind it. And there's not just one way to get to a multiverse — numerous physics theories independently point to such a conclusion.
My Own Server Part 1: DIY 1U Rack Servers : Introduction
The 19" form factor for rack servers represents a pervasive set of dimensions. There is hardly a component that does not accommodate this server form factor, including switches, and routers, patch panels, USVs, KVMs and, finally, complete computers. The main advantage of a 19" case is how it can save space by accommodating components that can be stacked on top of it.
Quantum gas goes below absolute zero
PHOTOCREO Michal Bednarek/Thinkstock Temperature in a gas can reach below absolute zero thanks to a quirk of quantum physics. It may sound less likely than hell freezing over, but physicists have created an atomic gas with a sub-absolute-zero temperature for the first time1. Their technique opens the door to generating negative-Kelvin materials and new quantum devices, and it could even help to solve a cosmological mystery.
How-To: USB Keyboard Breakout Board
If you’re building a standalone project with an embedded PC (say, a CNC rig or a MAME cabinet) one of the easiest ways to get instructions to the software is using the PC’s baked-in keyboard interface. But if you don’t want to actually use a keyboard to control the thing, you need some way to convert button presses and/or joystick movements from your custom control panel into signals that look like keyboard input. In this offering, UK hacker Rupert Hirst shows us how to reverse-engineer the key matrix on a scrap keyboard and attach a breakout board, ready to wire straight to the switches in your custom control panel. Sure, manually mapping the membrane switches with a multimeter may be a bit tedious when compared to using a drop-in keyboard simulator like PoLabs’ PoKeys, but it’s also a lot cheaper, and a lot more instructive.

Veronica – EEPROM Programmer « Blondihacks
An onboard way to program an EEPROM, or fake one. Well, now that Veronica is up and running in real hardware form, she needs some real ROM to play with. That means I need a way to burn an EPROM (UV-erasable) or flash an EEPROM (electrically-erasable).
7 Man-Made Substances that Laugh in the Face of Physics
The universe is full of weird substances like liquid metal and whatever preservative keeps Larry King alive. But mankind isn't happy to accept the weirdness of nature when we can create our own abominations of science that, due to the miracle of technology, spit in nature's face and call it retarded. That's why we came up with... #7. Ferrofluids What do you get when you suspend nanoparticles of iron compounds in a colloidal solution of water, oil and a surfactant?
