computer hacks
We’re not 100% sure what exactly is going on here. It appears to be a massive evaporative cooling rig for a computer, though the title has us wondering if it doesn’t have any other uses. There isn’t much of a description, but we felt the sheer magnitude of this cooling system warranted some publicity. Some digging around shows that this was out in 2003, but it is new to us.

This came in on the tipline: [Ville ‘Willek’ Kyrö] wanted to build a fully passively cooled computer. That means no fans at all. He started with scrap aluminum heatsinks, ripped apart a cpu heatsink to get the copper heat pipes, and began surrounding the boards with heatsinks to form a case. Cooling down the powersupply was the hardest part, as it did not lend itself to the flat surfaces of heatsinks. Any passive case with powerful components will inevitably be huge and heavy; this one weighs over 20 kg. He says, “It might not have been worth it, but it sure was weird watching the computer boot up with no sound at all”.
[acabtp] has already started hacking on his Dell Mini 9. He wanted to add GPS functionality, but didn’t want a dongle or anything external. After ordering the smallest GPS unit he could find, he found a place to wire it in internally. The end result had no bearing on the external looks of the computer. I wonder if he used the modification guide dell released?
Marketed as direct competition for the EEEPC, we’ll probably start seeing a lot more hacks for these. We’ve already seen the EEEPC taken hacked more than we ever expected.

In a bit of serendipity, reader [Tim Molter] had decided on the IKEA Helmer cabinet for his new cluster right before seeing the previous IKEA cluster we covered. He and his coding partner recently completed building their own version of the IKEA Linux cluster. The cabinet was $30 and holds six headless boxes. Each board has a quad-core AMD processor for a total of 24 cores. They also feature 1GB of RAM and an 80GB laptop SATA drive. The latter was chosen because of space limitations in the case. [Tim] describes the Helmer cabinet as being almost perfect. The power supply lines up with the top edge of the drawer and the motherboard fits with a millimeter to spare. Power buttons were added to the front plus slots for airflow. It looks like a really clean installation and at $2550, incredibly cheap for the processing power.
Normally case mods are all show and no go, but [Fredrik Perman] and [Michael Stabile] took their old render farm and made it a working showcase for the front lobby. This is a perfect combination of function, beauty, and practicality. It is a great conversation piece, allows easy working access, and provides a tremendous space savings in one sweet looking wall-mounted case. The frame is aluminum, the back consists of sheets of polished diamond plate, with a clear acrylic sheet for a cover. The case sides are left open to allow the blue LED fans to circulate air. Cooling a render farm crammed in a closet can be quite difficult, but isn’t a problem with this open design. This build is also much prettier and maybe more manageable than the setup in ExtremeTech’s Build Your Own Render Farm article.
There are a few more pictures after the break.
[Plusea] made her own touchpad using some anti-static gloves and an Arduino. This proof of concept is fairly small, but the system could be scaled quite large if you could find the fabric. She cut apart the anti-static glove, mounted it and wired it to the Arduino. A special piece is made to fit over the finger that is also wired to the Arduino. The location of where she touches is determined by the resistance between the finger and each corner. Watch the video on the instructable to see how it measures.
She mentions that there are a few different ways to build it, some which would not require anything on your finger, but would use another piece mounted behind the touchpad. The method she is currently using though, would allow for the fabrick to be any size or shape, even molded around something.
Maybe you saw the previous post and thought, “Well, that’s all well and good, but why is such a stylish case being used to ventilate cat feces?” Antec has heard your cries and has created a computer case with all the lovely curves of a litter box and just as much airflow. The Skeleton case has an open frame design with a 250mm fan on top. You mount the motherboard to a sliding tray. The power supply and hard drives are mounted underneath. It’s an interesting idea and easily replicated, but if cooling had been the goal, it would be a lot more enclosed. You can see the case with components installed on TweakTown.
