New Android App Encourages Users To Throw Device As High As Possible 156

        Which was wrong. Refusing to play may prevent a loss (or tie), but that does not constitute a win. Does a baseball team score a win for each team if the game is rained out?

    • Heh heh.

      I was just thinking this is something like a skill-based version of the $1000 "I'm rich" app. Show off your high score and total disregard for the various costs of breaking your phone. Ideally the app should keep track of your number of "losses" and prominently display your phones/week score.

  • Tie a string to the phone and spin it in circles. New world record and no broken phone.
    • When you throw something it experiences momentary very high gs followed by zero gs (except from air resistance). I doubt you can simulate that with a string.

        My fancy trick yoyo begs to differ - what you've described is, essentially, "walking the dog"

        • My fancy trick yoyo begs to differ - what you've described is, essentially, "walking the dog"

          Uhhh, no. The snap of sending the yoyo to the end of the string is a high acceleration, but while it is spinning on the ground it is feeling 1G. It is that 1G that keeps the tiny amount of friction from the string from catching the hub and ending the trick. If the yoyo wasn't pulling against the string it would easily catch and strart to wind back up.

          • Yoyo, yes.

            Extrapolate the same movements to a phone on a string - since it's not spinning on a free axis (like the yoyo), the force at the end of string travel is effectively 0g.

              The phone at the end of the string is subjected to much more than 1G as you spin it around. It is that force that is keeping the phone from simply dangling at the end of the string. Why do you think you need to pull back on the string so hard if there is "0g" on the phone at the other end? That pull you exert is the "equal and opposite" part of the laws of motion. It is the same principle that makes centrifuges work; the rotation of the centrifuge creates HIGHER forces (more g's) on the thing being sp

              • Thank you for clearing that up. The misconceptions/ignorance about basic physics displayed in the string/yo-yo comments makes me think that an app graphing accelerometer output (3 axis and/or total) as a function of time would be an eye opening demonstration to quite a few people. Much more useful and educational than a phone throwing app. See what happens when you shake the phone, hang it on a string, spin it on a string. Of course you can throw the phone too-- figuring out how far up it went could be left

              • The rotation of the yoyo is not why there is 1g during "walk the dog". There is 1g experienced by the yoyo because it is subject to the earth's gravitational field and is being prevented from accelerating downward by the carpet/floor it is in contact with. If you simply hang a phone from a piece of string, it will experience 1g because the string will be pulling upwards to keep it from falling to the floor.

                I knew that... must not have ingested enough caffeine yesterday...

      If the developers have half a brain, they'll check for deceleration up and acceleration down according to gravity.

      I'm thinking a 20 foot vertical air cannon with a throwaway phone, the phone encased in foam in an aerodynamic shell. But then they may factor in human strength limits too.

        deceleration up and acceleration down according to gravity.

        Sorry, you fail physics. As someone has already pointed out, once the phone leaves your hand, and if we neglect air resistance (which would probably be negligible), then the phone will measure *no* acceleration at all at any point during its rise and fall. Determining how high it was thrown is likely done simply by knowing how long it was in free fall, and how strong the Earth's gravitational field is.

        • If I let go of an object from my hand, and it doesn't accelerate towards the ground, then it will never hit the ground. That seems unlikely.

        • if we neglect air resistance (which would probably be negligible), then the phone will measure *no* acceleration at all at any point during its rise and fall.

          When anything falls to Earth under gravity it is accelerating at ~9.8m/s downwards. The reason why you are weightless during free fall is because you are not resisting the acceleration.

          Sorry, you fail physics

          Ironic, no?

            Einstein says "wrong" [wikipedia.org].

            From this principle, Einstein deduced that free-fall is actually inertial motion. Objects in free-fall do not really accelerate. In an inertial frame of reference bodies (and light) obey Newton's first law, moving at constant velocity in straight lines. Analogously, in a curved spacetime the worldline of an inertial particle or pulse of light is as straight as possible (in space and time).[2] Such a worldline is called a geodesic.

  • Next up: the app that uses accelerometers to detect sudden deceleration and encourages you to throw your cell phone against the wall as hard as possible.

    Because, really, why take chances when you can have a sure thing?

  • Cool.
    Now what they need is an app that detects when it's pointed at the ground, and snaps a couple of pictures!

    • Based on my image gallery, mine already seems to have a variant on that: whenever I ask it to take a picture of something outside my car, it waits until it detects that it's aimed at my steering wheel, dashboard, side mirror, etc. instead. (I've heard it's related to the well-known one that waits to photograph a pet until they're either in motion or showing off their privates.)

    Step 1:)

    Purchase a waterproof smartphone enclosure from a sporting goods store. Like say, these generic ones. [aliexpress.com] insert the phone inside the protector, and seal it.

    Step 2:)

    At the local post office, purchase a normal cardboard shipping box. I understand walmart also carries these. Then, buy a can of expanding foam insulation. Squirt the expanding foam insulation into the cardboard box, then, while the foam is still expanding and workable, embed the enclosure inside the foam. (You want to be able to get the phone out of the enclosure later. Keep that in mind.)

    Step 3:)

    Load the cardboard "shock box" into a "pumpkin chucker" trebuchet. You may need to troll newspapers or craigs list to find someone who has one. (they tend to advertise having them [pumpkinfarm.com], so all you need to do is look.) Set the angle nigh, then let it rip.

    • Load the app up in an Android emulator, and feed the accelerometer canned data to simulate orbiting the earth. Indefinite freefall! High score!
    • someone puts their phone in a model rocket

      You know, I thought about that, but two problems: model rocket motors are not very powerful. Your standard D12 motor is designed to output 12N of thrust. Your .25kg phone* + .25kg rocket** is being pulled to the earth with a force of (.5 * 9.8) = 4.9N. So you get a net upward thrust of 7.1N for right about 1.5s. For the hypothetical half-kilo load you get 14.2 m/s^2 for 1.5s. This gives you a max vertical distance (discounting wind resistance and suchlike) of d = 1/2(14.2)*((1.5)^2) = 7.1 * 2.25 = 15.9

      • Relevant "What If" XKCD [xkcd.com]. TL;DR. The average person can throw something about 15 meters high. Someone with a good arm could throw about 25 meters. Even the best of athletes could probably only throw 80 meters high, and that's using a golf ball, which is pretty much ideal. Really people aren't good at throwing things up, and are much better at throwing things horizontally. The comic assumes a device which converts forward speed to vertical speed without causing the projectile to lose any energy.
      • The important thing to consider when throwing (or launching) a phone in the air is how are you going to save it from impact.

        Sure, you could probably thrown your phone 45 feet or more into the air - but could you catch it? Would you dare, considering how much a replacement might cost?

        But, you could launch it - and allow it to be carried down by a parachute.

        And you might use 2 or more motors. If you're going to such lengths to cheat - why not cheat it up right?

      • Thank you for the ballistics calculations. I think that the phone throwing app would register a much lower throw than your calculations predict. Presumably the app measures the time of 0g acceleration. In that case, this would start at the end of boost, ie when the rocket motor burns out and then end when the parachute opens (sudden jolt followed by constant,1g, fall to earth).

  • I'd just put it on my quadcopter drone and fly that sucker straight up to the FAA-mandated flight ceiling for such craft; 400 feet ABL like it was nothing.

    Take any random idea and code it. Post it on /. and two things happen:

    - People find prior art of it, to different degrees of precedence.
    - People start finding ways to improve/cheat the system, to different degrees of sophistication, complexity and plausibility.

    Electronic device IQ tests...

    I wrote a program on a similar principle in 1983. It ran on a mainframe, and was called "He-man, Dangerous-man". Here's how it worked:

    1) Draw an ASCII art carnival hammer strength meter
    2) Put up text on the terminal telling the user that it is a strength meter
    3) Tell the user "When I say 'go!', hit the return key as hard as you can!"
    4) Count down from 10, and then print "go!"
    5) When the return key is hit, make the little ASCII art "weight" go a random amount 2/3-3/4s way up the screen toward the "bell"
    6) If the key to the left of the return key is hit, make it go all the way up and print ^G so you can demonstrate superior strength

    Obviously, I was forced to remove it, the first time some idiot actually fell for it and broke the keyboard on a Televideo 912 terminal.
