    Here [army.mil] is a link to the Army Landwarrior system which uses ruggedized 4x1x8" dual-processor pentium systems to help foot soldiers. It's part of the Advanced Warfighting Experiment [army.mil]. The systems are encased in gel to ruggedize them, cool then and shock proof them.

  • No, we don't really have "space". We just have "zero-g". :o)

    Nothing mentioned so far would properly operate *outside* the space shuttle when in orbit. I imagine such a machine would have to be hardened enough that it would also operate just fine underwater - and in any environment it is possible for a suitably protected human to visit.

    This sort of device would probably be a requirement for any future manned expeditions to the moon or mars - a mobile computer for data collection, mapping, email, reading /.

    Those machines would be the ultimate road-warriors...

    (Which brings up another point - how would remote internet access from another planet be handled - with round-trip signal delays of minutes rather than the seconds that the current generation of zero-G space hardware is designed to deal with?)

  • Ummm...could I take my laptop in my shower or surf the net while bathing? That sort of thinking scares me....ussually, when someone takes an electronic device into the bath with them...it is for FAR different reasons then surfing the net...more like making some *toast*


  • Don't know, but I know they can run at 100 Deg C.

    My uncle works for GoodYear in their internal systems design department. I am told that the machines that they stick out on the assembly line must be super reliable. (ie, they can't afford to close down an entire section of the plant so that a human can enter the highly toxic/hot enviro. to fix a broken box.)

    So, during the testing phase, I am told that they litterly seal up the box (they run i486 cpu's w/their own motherboards), hook up the sealed mux cable, start the canned software, and then toss (no joke) the system into a tank of fluid kept at approx. 180-208 Deg F. (if my memory serves me correctly) for 2 weeks.

    I have no idea how the cooling works. I just know for a fact that it is done. Apparently there are a LOT of trade secrets in this stuff.

    Just FYI,

  • Hmmm, assuming this isn't just trawling, has it not occurred to you that there are plenty of working divers, who stay down a *lot* deeper than where it takes just a few minutes to come up again. Also there are divers who spend an awful lot of time underwater such as oil-rig divers etc, for whom having a computer to log faults etc would be very handy.

    Not that I'm an expert or anything - deepest I've ever dived is when I've dropped the soap in my bathtub!

  • Okay, a couple things to comment on here.

    1) Once science invents a computer that can withstand blast forces and still operate with a melted processor, nuke blasts are covered.

    2) Vacuum tubes are immune. The old style MiGs in the Russian Air Force were immune to the electromagnetic pulses from nuclear weapons. The U.S.A.F. planes were exceedingly vulnerable because they have every shiny nice new toy that the Air Farce wants to put in there, wherein it becomes next to impossible for one of those overpriced monsters to fly without electrical power. The MiGs didn't have the best glide ratio, but they could still operate in the bounds of the EMP.

    So, if you want to make a computer that goes back to vacuum tubes and steam powered analytical engines, you could make it nuke-resistant. Either that, or slap 4 inches of lead on every side of the case, peripherals and cables.

    I think the lack of a keyboard is bad, but I guess needed in such an environment. I wonder how they make the monitor work? The interesting thing is that (despite the I/O connections) you could waterproof a current computer with something as simple as epoxy.

    Back in the '80's the guy who taught me BASIC on a TRS 80 was working on some sort of encrypted security sensor (I was allowed to see it, and only know a little of what it did, but hey, I was 11 at the time!) Anyways, since the sensor and its electronics had to be in a variable environment, what he did was encase the electronics in epoxy. The small board and chips easially fit inside an ice cube, and thats exactly how he encased them. He left the wires for the power and sensors out of the ice cube tray, then poured epoxy into the trays. Bingo. Totally encased eletronics. Now this did not look too great, but it worked...

    You could do a similar thing with todays electronics though. the only problem would be the power supply and peripherals (and TOTAL lack of upgrades....) (Cooling would be easy, use a water-soluble material to mould around the heatsink, when the epoxy sets, wash away the mould, leaving a hole to the outside.

    Thats my theory anyways. I think epoxy would work. (At least to a depth of 30 feet, I don't know if it could handle the pressure of say 150 feet. You would have to design the system carefully for those depths!)

    Of course, I guess that simple pressure cases could do this just as easially simply hook the system up to the bcd and it should work for keeping the system properly pressurized...

    Just some random geeky thoughts...
    I feel like encasing one of my 486's in epoxy now to try that out....

  • ...but I'd sure like to see a laptop that could be safely and effectively used during sex. Just think of the extra stimulation that could be gained while pr0n-surfing while getting it on with your (we hope) flesh-and-blood mate!

  • Sure thats soda you keep spilling...
  • So I'm thinking, Why would an underwater computer be necessary? While under the sea, you happen to come across a great find or area that must absolutely be logged into your computer? Is it so important that it couldn't wait the several minutes for you to get back up into your boat and log it in then?
    Don't get me wrong, I'm certainly not anti-technology, but I think proliferation is better used elswhere. When I'm underwater, there's a lot of other things that I've got my mind on rather than downloading my e-mail, overclocking my Celeron, or anything pertaining to my computer for that matter.
    Even for serious government-funded research. the computers should stay onboard the boats and leave the divers to explore in a hands-free environment.

  • Under water wireless networking is a much harder problem than you might expect. Electro-magnetic Waves don't travel very far in water, so you'd have to line the ocean with repeaters...

    It might be possible if the diver had a bouy above where he was diving. He would transmit to the bouy (that he couldn't be too far from), and the bouy would repeat the signal to a ground base.

    It'd add a bit of latency, so quake while your diving would still be out of the question :)
  • Would sound waves work better? They can travel very quickly under water, and although it'd be an analog signal, I'm pretty sure you could get more than 56k...
  • I don't think the keyboard is that big a deal. Use the hall effect sensors, or other non-physical sensor systems. That way the keys of the keyboard can be open and exposed to the water - no pressure differential.

    What other frontiers or environments are left for computers to work in?

    What about very hot environments? It would be pretty easy to make a computer work at very cold temperature, but what about one that would work at very hot temperature like would be needed for a mission to Venus (200-400 C). This is really a fundamental semi-conductor problem. Does anyone know what's the hottest environment they've managed to make a processor run so far?
  • I'd love to see some of this technology perfected, commercialized and made lighter. Not so i can dive, but so I can have a laptop I can really throw around, if you know what I mean. Laptops are still relatively delicate, I would love one I could treat like any other notebook.
  • Ziplock bags are about 5 &#162 each. :)

  • Think about it you can overclock your computer and not have to worry about cooling. At 60 meters down the water is a constant tempature. So overclocking the heck out of the processor(as long as it is set directly on the metal case) you would not have to worry about needing more cooling.

    Though it would make it pretty hard to change cd's.

    does the internet go that low?
    Though the fish might get annoyed by to many MP3's playing. As sound travles better in water...

    Upgrade to P3s and eliminate your hot water bills! Not to mention that annoying fan noise.

    Great idea!

    And when I'm taking a dump and a piece hits the water a little too fast, the water that sprays up from the bowl will give me third-degree burns.

    On the other hand, I will agree with you that it does have its merits. Certainly, hot water in the toilet will probably reduce the incidence of stains and things in the bowl.

  • Y'know, they make those keyboard condoms for the *food* industry, ya skanks. Maybe he shouldn't do those things above his keyboard.

  • "What other frontiers or environments are left for computers to work in?" How about in the human mind?

  • It'll blend in with the water. Camoflage computing!
  • The interesting thing about keyboards underwater must be the same challenge as underwater cameras. I've taken the crappy underwater disposable cameras down to 80' before with no leakage of the housing. The reason they are rated for no deeper than 10' is because once you push the button to take a picture below 20' or so, it stays pushed! You have to return to the 10' ceiling for the spring to overcome the water pressure and push the button back out. The challenge would seem to be getting some kind of set-up that the spring was strong enough to overcome the water pressure while not so strong as to be un-pushable with the finger tip.
