From a thermodynamics standpoint this project is damn near pornographic. The goal is to cool both the CPU and GPU down to -100 degrees Celsius using a dual evaporator cascade system. The project is fully documented starting with making the CPU/GPU blocks and polishing them to 0.005 microns. Next step is the case build up followed by a ton of brazing. He got everything assembled and pressure tested with only a few bugs. Right now they’re troubleshooting the system. They can get one of the heat exchangers down to -48.9degC, but not both. I’m sure they’ll get through this. Head over and check out the beautiful work they’ve done so far.

We’ve been linking to a couple proxy options in the links posts recently and [tom] thought it would be a good idea to write up how to use Privoxy. In [tom]’s case he wanted to route all of his internet surfing at work through an encrypted tunnel to his home machine. The guide is Windows based, but it won’t be to hard to translate to your OS of choice. It starts by setting up an OpenSSH server and new user on the home machine. Then Privoxy is installed. Next PuTTY is used to establish the secure tunnel from the work machine. The last step is to configure the browser to use the proxy. You can use this for IM too. You may not need this at work or school, but it should offer you some decent protection if you’re out using open access points.

Lew’s wheels is a great resource for building your own gaming wheels. It has advice on components, mounting and wiring. Not satisfied with just wheels? There are plans for pedals and paddle shifters as well. Full pin charts and calibration advice are also available.

No there aren’t a lot of good reasons for building your own laptop. If you’re an Acorn enthusiast you don’t really have an alternative. It’s got a nice metal case and the hinge has been designed to balance the screen. It looks pretty slick; the only unfortunate thing is that the LCD has to be plugged in externally.

Sure, I’ve known for quite a while that Linux is good for scratch building devices like routers, but I never considered that there might be an online community dedicated to doing exactly that. It isn’t just Linux either; whether you want to run Windows, DOS, BSD or Linux, RDP has compiled summarys and links to the software you need. They’ve got a gallery of projects that you can rate and luckily only a few feature cardboard. If you’ve got some specialized networking needs this is definitely worth a look. Me, I’m going to remain firmly entrenched in my WRT fanboyism.

Reader Jay was so mesmerized by the original oil computer story that he had to try it out himself. He had other good reasons: producing an experience report in English and creating a case that didn’t look slap-dash. It turned out to be a partial success and definitely a lesson. First thing he discovered was how not to oil proof a hard drive. He does get the chance to use the phrase “rock out with my caulk out”; which only goes to show: if you mess with bad puns, you will get burned. The rig did drop the computer temp quite a bit and Jay’s got numbers to prove it. Within hours of completion the case developed a fatal crack and redistributed the oil to the floor. Better luck next time Jay. It has been a couple months since the first story so if you’ve completed a similar project feel free to post your pics and/or comments.

No, I never wondered what meteorologists did when they were bored. I’m happy to discover that they’re building slick little devices like this. It is a mini-ITX based system that uses StormPredator for the generating the display. Everything is housed inside an old marine weather display. It is a really thorough write up covering the entire build process even covering bugs found along the way.
