Underwater Calculators?
Posted by Nick on 4 July 2000, 19:48 GMT

I have absolutely no idea what value this would actually have in the consumer marketplace, but it looks like an underwater calculator has been developed by Roberto Guerra. I'd love to see someone try this with an old piece of junk, like an 81 or a 92 :) I heard a little about electrically inert substances such as 3M's Fluorinert from Slashdot a few days back... a good link exists on the subject, as does information on the Cray 2, which used Fluorinert to cool it.

The downside to Fluorinert? It's $500 a gallon. Dang.

Re: Underwater Calculators?

What? Underwater calculators? Why would we need them? Probably just to play games that we don't even like that much! :-) Happy 4th! Cyaalll8r!

> Underwater calculators? Why would we need them?

Well, I see you've never been SCUBA diving.
A calculator may not be very useful, but if someone could program a depth gauge in it or something, that would have LOTS of use in the SCUBA communtiy.

Most dive computers cost $100-$700. If someone could build a much cheaper one, and sell it for less, you could corner the market. :)

Is it just me, or could we submerge our computers in Fluorinert and run it through some sort of radiator/fan thing and overclock a lot?

You could, but why? You'd have to carry a giant bag of Fluorinert around wherever you wanted your calculator. And it still wouldn't be as fast as your computer.

I am accepting illustrations of that ... so that I can laugh harder than with the images I am imagining right now.

I don't know about you, but I've found that my imagination is better than most illustrations at most things.

i read an article somewhere that a guy wanted to over clock his CPU
so he submerged his entire system in "Liquid Nitrogen coolled florient"

that is just beyond extreme

well you have to remember that the Fluorinert is $500 a gallon and 2 gallons were needed to cover teh entire computer then you need something really cold to cool the Fluorinert both liquid nitrogen are expensive and the disapate into the air so you will need to constantly buy more.........if your going to spend that much money just get a new faster computer

To heck with flourinert...

Forget flourinert, I've got an old 486 motherboard immersed in mineral oil right now and working beautifully. Mineral oil is cheap and doesn't conduct. Do a search for dr. ffreeze on google and read the cached pages about his adventures with mineral oil and the cooling coils out of an old A/C (unfortunately, dr. ffreeze's site is no longer up). You could also do a search on slashdot for it and read the comments for more information (I believe the story was posted about a 5 months ago, iirc).

I made an underwater mp3 rio.

I took a $150.00 RIO that plays MP3's and dipped it in tool handle coating. it works fine when I go lap swimming so I figure since the same electronics are involved that it would work with a calc. If you would like to see a jpeg of it, just e-mail me at spigget@usa.net.

Yes, yes I would.
I happen to be the proud owner of a $0 Rio myself :)

Now do you only have to dip it once and then its permanent?

Where are ti's message boards.

I tried to enter their boards, it said file not found. Did they finally cave to the trolls? I am hopping this time you won't delete this post like you did of that constructive post I did that one time in the solar list that was on topic.

Kewl... Now all we need is for someone to make a driver so the Calculator can be an extension of the computer. We can call it the "T" drive or something. T:\89\Main\Pheonix.89p
Hey, it could happen...

I reckon better would be a website where you just checked the games you wanted to play for your calculator, and it would automatically download them from the net and upload them to your calculator would be better.
You see, I'm a lazy git. Problem is it would need to be V4 browser only... :(

How about a linkport-to-USB port device, with a chip that emulates a USB storage device? That would need no drivers, be cross-platform...
