$1,000 Spray Makes Gadgets Waterproof
Rio writes "A new $1,000 spray claims to protect notebook computers, iPods, cell phones and other electronic gadgets from liquid, making them completely waterproof, a Local6.com report says. A creator of the technology said it could be used for emergency first-responders, bio-medical devices and historic preservation." This might be a bit of a flashback from last year.
The FAQ for the Golden Shellback (what they call this stuff) site says:"9. What aspects confuse people most about this process:
a. People get confused and think this is a spray. It is not, the coating needs to be applied in a piece of equipment.
b. People seem to wonder a lot about the contacts and how they are sealed. The contacts are not, the surfaces are sealed. So, water can run in and out.
That right there ought to deal with a lot of the statements and questions that are about to be made in this thread.
It's hard to believe that's how Micronians are made. Why don't we see it right now by having you both kiss one another?
In order to waterproof anything electronic, every entry point for water needs to be completely sealed. Does anybody else see the problem here? Yes, that Blackberry might still be powered on. But no, you probably can't depress the keys any more and you almost certainly can't charge it or plug in headphones.
Also, 0.001" thick? I bet it scrapes off on accident rather easily. I also highly doubt that anybody could apply a coating that thin from a hand-held spray can.

From the FAQ on the website:

Geeks like to think that they can ignore politics, you can leave politics alone, but politics won't leave you alone.-rms
Sounds like a conformal coating which is nothing new, you can buy a can of the spray on type at your local electronics store for a few bucks.
That is true. The motherboard inside it could crack from pressure, The multi-touchscreen could become inoperable, the screen could warp, and I can 100% guarantee that the speakers would blow out.
Not to mention you would have to prepare yourself for the bends if you ever manage to get that deep ;)
Like a month ago we had to make something IP54 Compliant This is part of the IEC 60529 Standard

So even though I am the Linux Software GUY, I started to investigate water repellent coatings.
I think they are just using a hydrophobic coating.

Hardly worth $1000 a bottle.
Similar to Scotchgard, Rain-X, Aquapel, Jigaloo, RainClear and Magic Sand.
These use Organosilanes like Trimethylsilanol (TMS) (CH3)3SiOH, or perfluorooctanesulfonates (PFOS) C8HF17O3S.

Look at the fluorene chains on this one,
fluorocarbons are the basis for things like Teflon and Fluorinert that don't react with anything and so in Teflon's case make good non-stick surfaces.
Unfortunately Scotchgard has been "reformulated" to make is "safer" PFOS never breaks down, good for electronics, bad for people and the environment. the new Formula (Perfluorobutane sulfonate PFBS ) is designed to break down after a month, so you'd have to keep reapplying.
If you want to research this further see Patents, 3574791, 6676733, and 6994890
Also get on youtube and look up magic sand, some cool videos there.

Hate to say it but 3G (1900MHz) is microwave.
3G isn't tied to any particular frequency. IIRC, AT&T is in the process of moving all of their towers to operate at 850 MHz because the range per mW is better. They've been working on that for some time. That includes 3G coverage.

Actually, water droplets are thicker than water. Go to a mattress store and ask about their mattress covers; buying a waterproof cover is pretty much mandatory for a foam mattress (think *sponge*), and the current level of technology stops water and allergens but not air.
Mattress sellers often have a demo device, basically a closed tube where one end is covered only by their fabric and the tube has a whole bunch of colored mouthwash in it. Air goes through it, but you can't shake the mouthwash out.
This would obviously ding fan efficiency, but fanless laptops already exist...
I would wonder about their claim of "Completely Waterproof" ... does that mean I can drop it in the tub and scrub it clean? There has to be a limit somewhere...

Regulators don't flow air until there is (slight) negative pressure...
normally, yes, however they have a purge button on them that overrides this and forces air to flow, quite useful for clearing them out, or using the regulator to inflate other things, or in case of a malfunction of some form.
During training to become SCUBA certified you remove the regulator from your mouth, hold the purge button, and breathe the air as it passes your mouth. This is a required skill as it will allow you to breathe even if there is some form of equipment failure.
Yes you do. The trick is to position your tongue so that it touches the top of your mouth as you breath in carefully. This stops the water from going straight to the back of your throat and causing a dangerous coughing fit.
You don't breath in too much water, really no worse than the first breath or two from a snorkel you just purged (where you use the same tongue technique to prevent coughing).
You learn this technique so that you can breath from a regulator that is in free flow which can happen when the diaphragm in the regulator fails. Normally you would try to fix the free flow under water (there's a couple of easy tricks you can try) but if that doesn't work you need to know this technique. In addition to sipping air from the regulator you would also theoretically be ascending to the surface as fast as you can safely since you'll quickly run out of air.
I don't know where the poster got the price of a grand. The site quotes a price range of $50-$70 for a cellphone or similar device.
