Fully Submerged Cooling

oil bath computer
Markus Leonhardt has taken the shortest route possible to liquid cooling.

  1. throw motherboard in fish tank

  2. cover in vegetable oil

  3. there is no step 3

Markus has been using this system for over a year. it is quiet and is cooled by the still functional fans circulating the oil. he has swapped components and even successfully used pulled hardware in other pcs. the pages are in the process of being translated to english, but the english forum is already up with links to other projects. I’ve got some extra hardware and fish tanks are cheap, so I’ll give this a try some time. I doubt my roommate will feel this is an improvement over my plan of just nailing the motherboards to the wall.

oh my gosh, look what we have here: some links. bet you guys didn’t see that coming did you?

now aside from cnet stealing certain ideas from around here, they’re also reporting that pgp has announced full hard-drive encryption. thus making it harder for hackers to get in.

and as for copy protection required by federal law? pshhh, forget it. Them 0, Us 1.
the uk is on the right path, how long until we catch on?

laser keyboards are up there with the piano necktie [zinquaff]
a $14 steadicam? you can’t beat that when you DIY [john]
tell your pc to take a chill pill using dry ice
violins, speakers, and sounds oh my

two things left. one is important, the other is really important.
important: lego jewelry is available…do you dare make your own?
really important: next time we have ourselves a lazy afternoon (read: wednesday), the senate will be voting for the real id bill. this isn’t good (despite it’s flashy graphics and sim-card-esque features) because freedoms are limited (once again), so check this out: unreal id

Remote Controlled Orb

poplight
Check out this wet and wild spring break story. Actually, Nate True spent his break hacking a tap light to make it emulate an Ambient Orb. It is wireless and you have full control over the color. You could have it indicate almost anything: new mail, rss feed activity, cpu temperature.  It isn’t a perfect copy of the orb: it is $100 dollars cheaper and you don’t have to pay any monthly fees. I guess that just means you’ll have more money left over to throw at other executoys, or you could save it and take a real trip next year.

though we may be hackers in one way or another, we still must think of the ones who put us here..
…so, a huge happy mother’s day to all and go spend time with your mother or at the very least, call them up and let them know that my birthday is friday how much you love them!

now that the links are off the grill and onto your plate, let’s see if you can stomach the fact that google probably got hacked, but they claim it was a DNS error (read: something bad happened)

this has to be one of the best things yet. remember that talking parrot at the toy store you’d always go up to and whisper some expletive in it’s ear? well now you can make it gawk away from the web.

who thought a worm could be responsible for 5% of all e-mail out there

and we end this mother’s day with what else: another exploit found in Mozilla browsers.

hot links tomorrow and by looking at the weather for this week, we might be in for some very lazy afternoons.

Proximity Card Spoofer

proximity toy
It is really hard to find good information online about proximity cards. I’m sure some companies consider this obscurity a form of security, but Jonathan Westhues demonstrates how severely flawed that notion is. He found a data sheet mentioning a 125kHz carrier frequency. He was off and running from there, eventually building a device that can read and repeat a proximity card’s data. It’s been argued that RFID technology is safe because of the short read distance. Jon actually found it easier to passively read cards that were being energized by a legitimate reader than by the device alone. Make sure you check out his home built PCB mill while you’re at the site.

you know it’s gotten popular when the manufacturers start throwing ideas at you [jake]

Linux is now running on the Nintendo DS. woohoo! [pingu]
interesting encryption methods…very old school
ipod to ipod. simple and fun.
oh linux, you treat us very well. we applaud you.

and we end with something that really is a marvel….the aussies from down under have come up with an encryption method that is 100% unbreakable by using diamonds and fiberoptics. first melbourne, then a phone to ip service, and now this. im moving, who’s with me?

DIY Projector From A Pocket TV

diy projector tv

since DIY projectors are all the rage, we thought it’d be cool if you could make one for yourself. you know, when you have that urge to go out and show the public your artsy film work. well now it’s possible, cheap, and effective thanks to this DIY projector made from wood, a pocket tv, magnifying lens, and some other stuff. you’ll need one of those old school pocket TVs (yes you’ll need a color one if you want color silly) from the 1980s to get it goin, but after that it’s smooth sailing.

thanks [stewart]
