Update: Foundation PC Cooling

[gigs], whose foundation-based PC cooling project we covered earlier, has posted his initial test results. There was a large debate going back and forth in the comments as to whether or not this would work, and hopefully this should clear most of it up. He used a 150W fish tank heater to simulated his system’s heat output, and used a quiet fish tank pump to keep the water flowing. Over 8 hours, he was able to maintain a constant temperature 16° C (61° F). While not quite frigid, this would definitely provide ample cooling for normal operation with some headroom for overclocking.

Chart of results after the jump.

[thanks to gigs for getting back with real data so soon]

Foundation Cooling

August 26, 2009 by James Munns 67 Comments

Foundation with Copper

Overclockers are always trying to come up with new, colder, and quieter ways to keep their PCs cool. [gigs] was so dedicated to this, he decided to lay 6 meters of copper pipe to use as a radiator in his new house’s foundation. As of now, the foundation is laid (copper pipes and all), and the forum posts come complete with finished slab pics, though there is no house to speak of yet.

Bench Power Supply Adapter

Every electronics workbench could benefit from having a bench power supply. Converting a PC power supply works, but often, it involves splicing wires and limits the supply to only bench use, and building one from scratch is definitely an undertaking. To counter this, [silic0re] and his father came up with a detachable adapter that simply plugs into the existing connectors. The adapter provides posts for four different voltages and can be built in no time. It’s nice to see a solution that will let you use any power supply laying around without having to worry about the dangers of opening it or cutting it up.

[Thanks silic0re]

A Linux Server That Tweets Power Changes

August 22, 2009 by Matt Schulz 21 Comments

Twitter has been used for lots of experiments, both useful and just for fun. [FIRESTORM_v1] sent in his project that falls under the useful category. When he wanted a way to monitor his server’s power statistics, Twitter was a logical choice. Similar to the Tweet-a-Watt, he wrote a script that posts messages from APCUPSd to a Twitter account that he follows, and gets the updates on his phone. [FIRESTORM_v1] documents all of the scripts he used and the steps to get your server up and tweeting.

OpenPogo, An Alternative To Pogoplug Software

August 21, 2009 by Matt Schulz 21 Comments

pogoplug

Many of us heard the news of Marvell’s SheevaPlug plug-in PC being released alongside its consumer solution counterparts. One of the prominent products based on the SheevaPlug hardware is the Pogoplug. The Pogoplug is essentially a no-configuration media server that allows you to plug in a hard drive and network cable to make data readily available anywhere you have Internet access. It’s a great idea, but the underlying software is closed source, limiting the demographic of the device to consumers who are happy with an out-of-the-box solution. Enter OpenPogo, a solution for people who want a bit more control over their device. OpenPogo gives users more say over what their Pogoplug does; from running a torrent client to a web server to a Ruby on Rails server. The possibilities for the device are limitless, and OpenPogo makes turning our ideas into reality it just that much easier.

Reverse Engineering USB Drivers

When [Jespersaur] purchased a Luxeed LED keyboard, he was disappointed to find that the drivers were not open source and didn’t support all the features he wanted. His solution? Hack the drivers that come with it, and implement his own. In his article, he gives a basic rundown of beginning reverse engineering by multiple methods and a brief introduction to libusb. For the Linux drivers, check out [Kurt Stephens]’s site, where he supplies a link to the source code, instructions on building it, and a tutorial on sending commands to the keyboard.

Modular Computing

This is the Illuminato X Machina, a “cellular” style computing system. Each unit is a fully functioning computer with its own processor, storage and communications. You can watch above as a change in the operating software is propagated across the grid. You can see the LEDs in the video going nuts, there are actually LEDs on the sides too. [Justin] described it to us as a personal fireworks show on your desk. This system is fully open with the schematics and source code available on their site. You might recognize these guys too, we covered their Open Source GameBoy.
