The Perpetual Clock

Atmos clock

 

 

 

 

When I fist read the description on how this worked I was totally amazed. The clocks never need winding by hand because the mechanism is powered by a difference in temperature. A variance of a degree between 15-30 C is enough to cause a liquid (ethyl chloride) in a sealed container to expand or contract and in turn wind a spring with a ratchet. The clocks are exquisitely made and are fairly rare. If you find on, even a non working one you can expect to pay over $2,000 US for it. I find the concept of a temperature driven clock fascinating. I can’t help but wonder if the dynamic properties of ethyl chloride could be used in other projects.

Network Attached Storage, a DIY Story

Network Atached Storage

If your like me you have way too many files on way too many hard drives. One way to help this is to have a network attached storage (NAS). Yeah, you could just stuff a bunch of hard drives in a beige box of death and load up XP. A few network shares later and you have a NAS. You could do that, sure, if you wanted to take the easy way out. But I can tell you want to live a little, be on the edge. Yeah… The Edge. It’s where the alpha nerds meet for a midnight snack of Jolt Cola and double stuffed pizza before going back to their tricked out 733t hax0r boxes. It’s where you want to be. Building your own NAS out of the cast offs from the junk bin of a local thrift store will get you closer to that edge.

So gather up your hard drives, your mother boards, your USB key drives (you want all the IDE channels open for drives man!) and grab a copy of FreeNAS (just about the coolest software for this sort of thing) and go to town. I’m working on consolidating my collection of hard drives (everything from 20GB to 120GB) into a big pile of storage that is at least running in RAID 1. RAID 5 is my goal but that’s only if the hardware gods smile upon me.

Like me, soon you will be on the Edge.

Floating Nuke Plant

Nuclear sub

 

Ok, I can kind of see how this might cause some people to run in terror. The basic idea here is to take a nuclear power plant (the kind that would have run a nuclear sub) and stick it on a big ‘ol raft. That would be moored in remote locations of the Arctic circle and used to power what have you. Research stations, small towns, your guess is as good as mine. Sounds cool, except if it sinks. Or if someone makes off with it. Yeah…

Talking Flames

Talking flames

How very facinating! 

Talking Flames, was in 1990, the newest technical achievement from the Logos Laboratory for experimental music research. It uses a plasma in ionised air, an electric arc that is modulated with a PWM-audiosignal. Herewith a sound-radiator is created that does’nt make use of any moving parts such as cones or coils. It sets air into vibration in a most direct way. Moreover, it is also capable of converting digital audio-information into sound, using the ionised air arc as an digital to analog converter by simply integrating the PWM- signal. This digital loudspeaker operates on a very high voltage and pretty high frequency: de carrier wave should be at least two times the highest audiofrequency. Ignition voltage is ca. 20kV. The electrodes are made of tungsten enriched with 5% radioactive thorium. The points have to be sharpened every so often.

 I’m going to keep an eye out for more information on this technique.

Defcon, The Game

DEFCON PC 

Funny how this comes only a few days after I forced my kids to watch the classic movie "Dr. Strangelove". Defcon is a game where both sides are going to lose, it’s just a question of who loses first (or the worst). It reminds me of the classic DOS game ‘Scorched Earth‘ (or the updated 3D version called ‘Scorched 3D‘) where your trying to kill the other tank with tactical nuclear weapons. Perfect relaxation on a Sunday afternoon if you ask me. The graphics are right out of ‘War Games‘!

Taking the role of our favorite Cold War nations, players duke it out on a retro style vector display. They begin with the careful placement of radar dishes and silos, then move on to feeling out each other’s defenses with subs, aircraft, and warships. Tensions rise, conventional warfare erupts, and it eventually escalates into a full scale nuclear exchange. Meanwhile, the computer calmly reports the death toll in terms of millions of lives lost. In a nuclear holocaust everyone loses, but through clever tactics, alliances, and well timed backstabbing, it may be possible to "lose the least."

Oh yeah, it’s a networked game so you can play with your friends. 

This is a game that needs to be played on the biggest screen TV you can find, in the dark, and after you’ve spent a day in a cold war movie marathon. ‘Multiple inbound targets are being tracked… Suggest counter measures immediately.’
