Hackaday Links

September 14, 2005 by 15 Comments

Congratulations to [Markie] for making it onto BoingBoing and MAKE with his Hack-A-Day iPod sock. I can Digg it. We know he’s just trying to shake the moniker of “cute bunny photographer“.

Episode 002 of NerdTV is available now, even though they haven’t updated the homepage. Fbz got a little impatient and decided to dig for it. UPDATE: It’s been officially released.

[Jon] downplayed his cd dividers when he sent in the link, but I think they look pretty appealing.

You don’t need a serial number to get a new Playstation AC cord from the recall. [Ozmotear]

[Wiltj] knows that no one will want to steal his Bazooka sub knockoff.

German gallery of UAVS [thanks dad]

[Seth fogie] wrote this roundup of PSP emulators and ISOs. This is actually one of the few reasons I’d buy a PSP since it has the correct number of buttons to emulate a SNES, unlike the GBA.

[sulk] modified his Playgear PSP case so he could use it with USB.

A beautiful gallery of old iron [j. peterson] UPDATE: There might be a trojan on this page. [Anon]

[sega01] saw our spudgun victim and decided to show some pictures from his laptop+fireworks period. What have you guys got against Toshibas? I just take my stuff to hazmat like a good citizen. I wouldn’t have if I had known I’d be hired here a week later.

[Jake] is going to hell for this link.

If you missed it in the comments [dick] sent in his friend’s April fools printer hack.

[jaa] modified his T610 cameraphone for IR.

Google recently rolled out Blog search. We’ve got a Google hack category now; if you come up with something clever/abusive send it in. Read the FAQ to get started.

I hope you enjoyed all of the linkage.

HOW-TO: Folding@Home Competitively

September 13, 2005 by 110 Comments

folding

UPDATE: For troubleshooting your F@H setup head to the unofficial Team Hack-A-Day forum.

After announcing the Hack-A-Day Folding Team last week it has become one of the fastest gaining teams. [BillytheImpaler] put together this great guide for not only getting started with folding, but also getting the best folding performance out of your machine. Read on and join the team so we can break into the top 1000!

From Wikipedia

Folding@home is a distributed computing project designed to perform computationally intensive simulations of protein folding. The project’s goal is to add greater understanding to protein folding, misfolding, aggregation, and related diseases. Such diseases include BSE (mad cow), Creutzfeldt-Jakob disease, Alzheimer’s, Parkinson’s, among others.

Folding@home does not rely on powerful supercomputers for its processing; instead, the primary contributors to the Folding@home project are many thousands of personal computer users who have installed a small client program. The client runs in the background, and makes use of the CPU when it is not busy. In most modern personal computers, the CPU is rarely used to its full capacity at all times; the Folding@home client takes advantage of this unused processing power.

Build Your Own Surfboard

surf

We’ve covered snowboards and longboards on previous Mondays, but it would be a shame not to mention their precursor the surfboard. [biscuitdough] suggested this online book by Stephen Pirsch for getting started with board building. The introduction does a good job of covering why you would want to pursue this and also reasons not to. It even suggests that reading the guide would help you if you plan on ordering a custom board. Make sure you check out the “Helpful Links” section for a description of their small wave design. (photo via)

-100degC Cascading CPU Cooler

September 11, 2005 by 8 Comments

cooler

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.

Ladyada.net Is Back Online

September 11, 2005 by 18 Comments

Yes, I’m going to dedicate an entire post to this. Limor is one of our favorite hardware hackers, but her site was unfortunately down last week when we picked it for Editor’s Choice. Well, she is back from vacation and has gotten the site back online as promised. Take some time to check out her great projects: the Minty MP3, Mini POV, and my favorite, the x0xb0x.

Mac Mini Robot

The University of Oklahoma wanted to get a good idea of what it is like to operate a robot using visual and aural sensors before they built one of their own. They started with the Pioneer 3-AT robotics platform. They added a Mac Mini and powered it using a 12V battery and an inverter (this was only a temporary setup). The Pioneer is controlled through a USB-to-serial connection. An iSight camera provides visual feedback. Turning control is jerky over the WiFi connection, but since this will eventually be an autonomous system it isn’t a concern. It is a nice quick proof-of-concept.

[thanks Jason Striegel]
