Track a Soda Can with GPS? 346

And in another bit of Coke news, they've got a new high-tech billboard: jhkoh writes "Reuters/Yahoo is reporting that Coca-Cola has unveiled an 'intelligent' billboard in London's Piccadilly Circus -- at 99 feet wide, the world's biggest -- that supposedly will respond to weather, movement, and SMS text messages. The billboard itself is 52 square meters of LED display. How soon before someone hacks it?"

Turns out it was at an old, practically adbandoned, city park. It appears to still be maintained, but in the several times I have gone back down there I haven't seen another soul.

Maybe it's hidden downtown, on the fifteenth floor of some office building. Maybe it's hidden on the other side of a small mountain range that you have to either climb over, or drive around. Maybe it's hidden deep in some cave. Maybe it's hidden in your backyard ... you never know.

    • I have had this argument many times, and am still very skeptical about GPS transponders.

      GPS (if that's being used, which is likely) is a one-way system, which means a passive device receives timing signals from a constellation of visible satellites, and uses the timing differences to estimate location and speed of the receiver.

      The critical question is what happens next to that data. It can't be transmitted back to the GPS satellites, since they are only able to receive control signals from their operator

    • I assume that these cans would have "chase teams" behind them, especially if they intend on awarding prize winners their prize immediately at the point of purchase. Therefore, the "GPS unit" won't need to transmit its coordinates very far, conventional shipping records should store or machine they need to stake out, and then when the device starts moving they know who to follow and hand the prize to.

      • There is no "transponder" because the satellites merely "beep" a signal containing the time, satellite position, and any clock correction necessary (there are also other components, but these three will suffice for this discussion).

That'd mean that receivers would have to be essentially ubiquitous. The only thing I can think of that might come close to fitting the bill would be cell towers.

A receiver picks up those signals from 3 or more satellites (even 4 or 5) and calculates the position from the time differences. Other sources of information, like wireless network base stations (GSM etc.) enhance accuracy. [end of very rough description]

    The idea was called "Magic Can", you'd open up your Coca-Cola can and real spendable US dollars just might pop out. Of course, the cans with the money in them wouldn't have cola, but instead a device powered by chlorinated water that would propel the bill.

    However, the device often got damaged in shipping, and this lead to several cases where a "winner" didn't look before they drank, and ended up digesting the chlorinated water before realizing that their can didn't really have any cola. Their $100 bill would end up getting spent in the emergency room...

  • the casio gps watch can barely stay working for a few days on its batteries, ditto geko and emaps... ok they can pulse it etc... and then there's the faraday cage issues and i think i can tell which can has the $1K of electronics in it and not 12 oz of actual sloshy fizzy coke... sounds like someone made them a promise that's going to be hard to keep... and if they can track down a unit with this much stuff coming out of it, seems it should be easy enough for some others to do the same, then it turns into '
  • I just designed a GPS-based delivery tracking system, and I kind of doubt this will work exactly as advertised. For one thing, your options for transmitting GPS information are limited: you can use cellular data networks, which have limited reception, or satellite networks (which the article implies), which are expensive and require larger transmitters. All of the combo xmit/gps devices I've seen are larger than Coke cans. Though a cellular-based one could be concievably made in about that form factor wit

    This is probably something the marketing boys came up with and released before they figured out it was not feasible. Here's why:

    1. The GPS satellites don't tell you where you are. A GPS receiver figures out where it is by triangulating its position by measuring how far it is away from each satellite. This takes some pretty advanced electronics which would barely fit in a soda can.

    2. GPS does not track. Nothing is beamed back to the satellites, and even if it were, it would not reach them without a lot of power and a high gain antenna. The most common ways to get realtime tracking information on a GPS receiver is to couple it with ground-based radio or cell network. This would have to go in the soda can along with the rest...

    3. GPS (generally) only works outside. The signals that GPS uses are very high frequency, weak, and thus very prone to attenuation due to obstacles. They COULD use the can itself as an antenna, but even that probably wouldn't give you enough gain to get the signal indoors.

    4. Power source. None of this stuff works without power. How are they going to propose to keep this thing powered while they have this thing stored in the back of a warehouse for god knows how long before it gets put on a shelf and bought? Even if you didn't have it activate until you, say, opened it, there's still a pretty good chance you will not be in a location where GPS signals can be acquired.

    Pepsi, please stick with the damned instant win cards.
    Oh, and you are planning on going though with this, it may not be a good idea to fill the can. :)

    For the upcoming Rugby Worldcup 2003 [rugby2003.com.au] in Australia, Coca Cola has this system already in use for their current competition (one could win in total about 50'000 AUS Dollar (10'000 Visa, Peugeot 206 XTR and VIP Final tickets) if he has the right bottle).

    Coca-cola will feature a promotion in which winners will be located by satellites tracking GPS devices implanted in the winning cans....

    You'll never look at the guy picking pop cans out of the trash the same way ever again...
