RFID Music Player

Posted by timothy on from the reuse dept.

frazzydee writes "I know what you're thinking, RFID tags used to play music? Well, it turns out that we don't need to take out our tinfoil hats this time, because it turns out that are some constructive uses for the same RFID tags that we have all come to loathe. Since RFID tags can hold 1 kilobyte of data, somebody who goes by dividuum found that (s)he could use the tags combined with a reader to store and play back music. Dividuum used SID files- the same format used on Commodore 64s- and programmed everything in C. Pictures of the RFID device are available here."

    Think of it like a midi file not a raw or compressed mp3/ogg..
    So its all those beeps, we love :)

    Think Fourier transforms. Many techniques can be used to encode music such that the quality is reasonable and the file size small.

    What did you think mp3s use to compress audio?

    RFID readers and tags are here, and they're here to stay -- mainly because they are -oh- so cheap. People often ask, "how can I build one of these things?" And, while I appreciate the coolness of building something like this, the real cool bit about RFID readers & tags is that we can build things with them very very easily.

    Phidgets is a company that sells these RFID readers and tags in an "off the shelf" manner. For a mere $90 CDN (almost nothing in USD), you can get a reader plus a whole set of tags (and of course the software to program against it with).

    Sometimes I'm just dumbfounded as to whether someone is being serious or not.

    Just in case you are, the grandparent is talking about a type of artificial fish.

    "Since RFID Tags can hold 1Kb of Data?"

    Not all tags are that small, my company makes a series of tags that hold a *considerably* larger data package.

    128K and up...
