    At one point we’ve all done it – spilt a drink over a laptop, gotten our tablets soaked in the rain, or even dropped our phone in the toilet.

    I've never done any of those things with my expensive tools/toys. It baffles me how badly people treat expensive and hard to replace tools. It's not limited to technology either; a friend of mine has a collection of rusted saws, screwdrivers and other tools because he's too lazy to bring them in out of the rain after a big home improvement project. Pathetic.

      I am a destroyer of keyboards. So I've learned simply to not buy expensive keyboards. Everything else, yeah, I try to treat gently, from my beloved Honda which is about to tick over 200K miles, to my late grandfather's violin 110 year old violin. Even my $80 mouse gets more care and attention and caution than my keyboard, though.

      My dilemma is this: If I get an expensive heavy duty mechanical keyboard, I will somehow managed to drop a gallon of paint on it no matter how careful I am. So I just use $20 el cheapo Microsoft Curve keyboards, which invariably wear out after a year because I hammer it so bad.

        I've killed two separate MS Natural 4000s, one about 30 minutes after getting it. It's very rare that I'll spill, but man, it seems like just a little splash has a high probability of rendering it useless.

        Personally though, the extra comfort of a comfortable-to-use keyboard is worth an occasional fairly-expensive (at least for a grad student) replacement. I never understand people who spend like $1500 for an awesome gaming rig or something and then get a cheapass keyboard, which is one of the couple components you actually use. But I might just be overly sensitive or something; I do pay a lot of attention to arm ergonomics as fallout from wrist problems many years back.

            (I'm well aware of the model M's reputation, but I don't find the better "button feel" to be anywhere near worth the noise, let alone the lack of a split keyboard or the Natural 4000's reverse tilt which I really really wish was more common. That alone makes typing far more comfortable; I don't understand why it's basically the only keyboard out there with that feature.)

        Now usually on most phones I've seen, the battery connects via bare copper. How can it still actually function, without allowing water to short circuit it?

          Water with ions in it, such as from salt or contamination, is conductive and will corrode. I'd like to see them dunk a "waterproofed" phone into seawater.

          My guess is that the video used distilled water, which is highly resistive. Water only conducts if it contains impurities.

          For the actual product, I would expect them to apply the coating with the battery already in, and you simply can't take it out without needing to reapply the coating.

          • Or the copper contacts have small plastic lips/edges on the battery/phone contacts, so they're watertight enough when the battery is seated (held in with the battery tension).

          I thought that too. I would suspect that it is thin enough that it doesn't prevent the flow of electrons between the copper contacts, but pushes the water away enough to prevent the electrons from flowing across them. Amazing yes, but it doesn't seem impossible.
        • Does this coating prevent conduction, or is it merely a method to avoid the corrosion water causes? That's the real problem - shorts are bad, yes - but that's usually not what kills a gadget.

    why is my $15 Walgreens watch waterproof to a depth of 20 meters, but if I sneeze on my $400 Android / iPhone it's ruined and I voided the warranty?
    • by QuasiSteve ( 2042606 ) on Thursday January 12, 2012 @11:37PM (#38682088)

      I think you'd have to do a little more than sneeze on it - but I am well aware of stories in the past where e.g. sporters who sweated a little (much) got told by the service center that the humidity indicators in their iPod (or similar) indicated the device got wet and thus the warranty was void.

      But just to address your specific example - your $15 Walgreens watch probably has little to no openings and whatever interface controls are there are very easy to make waterproof. Compare to the many slots and compartments on a typical smartphone which often are required to be easily user-accessible. You wouldn't want to have to unscrew the back of your smartphone every time you'd just want to recharge it (if it ran for 2 years on a few button cells like your watch, then that wouldn't be much of an issue).

      But, more importantly, your $15 Walgreens watch is $15. If they actually got a claim from somebody with valid proof that they only dove to 19.95m and not over 20.00m, sending out a new $15 Walgreens watch is a heck of a lot cheaper than going over that paperwork and trying to tell you that you must be mistaken.
      For $400+ devices, on the other hand, it's a lot cheaper to open it up, point at the humidity tags, and say "sucks to be you".

      why is my $15 Walgreens watch waterproof to a depth of 20 meters, but if I sneeze on my $400 Android / iPhone it's ruined and I voided the warranty?

      A couple of thoughts, here.

      1) How do the microphone, micro SD slot, speakers, and charging/data port on your watch work after you've taken it down to 20 meters?

      2) Has it ever occured to you that the makers and retailers of your $15 watch are simply banking (literally) on the fact that essentially nobody will every submit that cheap watch to 20 meters of water? And if someone does do so, and the watch inevitably fails, what percentage of that already tiny percentage are going to actually bother to pursue warranty service/replacement on something that costs less than a decent pizza? They could simply replace that costs-them-$3 watch every time all three people in that group take a shower, and they'll still make more money than they would have by not saying "Waterproof to 20 meters!" on the packaging and not having to service such claims.

    • why is my $15 Walgreens watch waterproof to a depth of 20 meters, but if I sneeze on my $400 Android / iPhone it's ruined and I voided the warranty?

      Your $15 Walgreens watch has rubber seals on the backplate and around any buttons/knobs.
      Your $400 Android / iPhone doesn't. If it did, the phone would be a lot bulkier.

      Looking at their list of "approved devices" [liquipel.com], I'm wondering how the nanocoating interacts with user removable batteries.

    How could you coat the interior of a microSD card slot that's covered with a loose-fitting cover and make it waterproof? If the nano-coating doesn't conduct electricity then any card you insert won't make contact with the contacts. If it does conduct, then it's useless as a waterproofing seal over electronics. The same would seem to hold true for any earphone plug or charging port, right?

      I don't know how it works for sure, but I imagine its just surface tension. The coating doesn't physically close the slot, it coats the outside of the slot with a film that repels water. Water doesn't go into very small places at routine pressure -- the raindrop-size drops you encounter all the time are its least-energy state, the "natural" curvature of water drops. The coating keeps water far enough away so this curvature radius doesn't contact the inside of the slot.

      Not only conductivity, but how does the coating hold up under the friction of plugging in the charger every day? If you peek at the metal contacts of a USB cable with a flashlight, I'll bet they have spots worn into them from being plugged in. I doubt any coating could survive that, and the parts which suffer the most wear are also the parts that need waterproofing the most.

        I have done Paralyne coating back in the 1980's. It is a vapour deposited plastic. If you are putting down Paralyne 'C' (the chlorinated version - there was no fluorinated version back then as far as I knew) then it could give a tough plastic coating that could be 100 nm deep. This forms a thin coating over all surfaces including under electronic components on boards. I have even seen it creep between stacks of microscope slides that aren't quite flat. This coating was transparent. If you put down a thinker coating you could get interference colours, and if you kept going it would look milky - particularly with Paralyne 'N' (the unchlorinated version)..

        Paralyne was a standard 'tropicalization' process for electronics to be used in harsh environments. You tended to 'tropicalize' circuit boards with masking over the board edge connectors. As Paralyne was good at penetrating, you probably could not coat anything with a 2-way switch, or plugs. But things like earphones and displays would probably be fine.

        Yellowing? I never saw it go yellow. It would have to go amazingly yellow because the coat is so thin.

    Prior to studying Computer Science in University, I went to college and studied Electronics Engineering. I worked for an industrial electronic design and manufacturing company for 3 years between one and the other. Most products went into the oilfield. Scada, wellhead controllers, remote sensing equipment, etc. When manufacturing circuit boards 50 at a time, they would put them into a commercial *DISHWASHER* to get all the water soluble solder flux off and wash the board clean. Because chips follow the original Texas Instruments Mach32 procurement process (as outlined by the US Air Force in the 1960's and 1970's), they are hermetically sealed, must past gross leak, and fine leak tests, thermal shock, high altitude testing, centrifuge tests, and other tests, water won't 'leak' into the chips and wreck them. When power is applied, damage can happen. When there is no current, electronics are inert. To keep things 'dry' under power, silicone spray can keep the rest of the electronics from creating short circuits (due to conduction through water, etc.). This was also important in highly corrosive environments (hello petrochemical plant). They also used Hall-effect keyboards and switches to eliminate any chance of an electric arc in hazardous environments (when a seal fails in a methane/ethane/propane plant and you need to press a button to shut off a pump to stop the leak, and pressing the switch blows up the plant you have failed). As stated previously, you can enjoy this new 'wonder technology', or you can get a can of silicone spray. Have fun!

    • When there is no current, electronics are inert.

      Galvanic corrosion can occur whenever two dissimilar metals meet and are provided with an electrolyte, so you might want to be careful about that. I wouldn't get anything with a copper heat sink wet, for example.

    Their site reads:

    If my electronic is accidentally exposed to water after being Liquipelled what do I do?

    Do not panic! Please follow the aftercare instructions such as drying the device as much as possible, powering down the unit (if it is not an emergency and you do not need to make a call), removing the battery and battery cover if possible and not restarting until it has dried. Please note not to charge your device for 24 hours until it has dried out.

    Most electronics will survive water contact if dried out. After all, one of the last steps in PC board manufacture is a pass through a dishwasher-like device. This "nanocoating" starts to sound like a placebo.

    It's lame that phones have connector holes in them at all. With inductive charging, Bluetooth headphones, and WiFi or cellular for everything else, why should there be connectors at all. I'm surprised that Steve Jobs didn't eliminate holes years ago on uglyness grounds.
