RFID Music Player

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."

    I don't subscribe to slashdot groupthink.

    I don't loathe any technology, only those that abuse it.

    Only some of the potential uses.

    I used an RFID card to get in and out of a city admin building all last week on site, it was much better than having to fumble for a different key for the umpteen different doors.

    Technophobic dorks. Invasion of privacy, and all the other paranoias you have are all social problems, not technical ones.

    Don't bitch about the tech, bitch about the people who would misuse it.

    Outside of the slashdot tin-foil hat crowd, I don't think anybody is getting really worked up over glorified barcodes.

    It's just a technology like just about everything else. It doesn't automatically make it evil just because some bad guys might use it or there is "potential" for abuse.

    Seriously, the RFID is evil meme is dead. Learn to deal with it.

    1 Kb doesn't seem like a lot of music. 1 Mb/min is the usal rate for at least decent encodings. That means that 1Kb would play ... 1/1024 min or approx .05 seconds. Ouch

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

      Your not taking into account the time-space-continueum (stupid). Try listening to Celine Dion, its so bad that 0.05 seconds would sound like a waste of hours.

      Judging from your high UID and your apparent inexperience with the computers of 1982, I feel fully justified in blazenly assuming that 1 Kb of YOUR music is MORE than enough. 0.058 seconds of "Dad won't buy me a car, homework sucks" is exactly the right amount.

      RFIDs can be made paper-thin and less than a centimeter square, so now they (you know who!) have put them inside every square foot of aluminum foil.

      For a good tinfoil hat, you need to get aluminum foil which is at least twenty years old. I suggest going to the dump and digging down a few feet- dig until you get to the really ripe stuff, then it's just about five more feet! The dates of

    If I'm not wrong, the average .sid file for the C64 takes up about 2K of memory. The sids must have been pretty small to fit on the RFID.

    Some interesting Commodore 64 music links:-
    The HVSID Collection [c64.org] - Which is the main site for the collection of thousands upon thousands of Commodore 64 sid files.
    Remix.kwed.org [kwed.org] Remixes of Commodore 64 tunes with real and modern synthesized instruments.

  • I know this is slightly off topic, but it occurred to me that RFID tags could actually be useful in terms of music.

    The value of music (or video, or software, or any other intellectual property) isn't so much in the media it's stored on, but in owning the license to legally play it. As it stands, when somebody purchases music, be it on a CD or in mp3 format, maintaining the license to the work can be a pain.

    CDs can break or be scratched to the point of being unplayable. Hard drives can be erased accidentally. Owners of the copy write do their best to prevent users to copy media because despite many users otherwise benign intent to transfer media to a different format or to archive owned media, there is no guarantee that they aren't copying the work for a more nefarious purpose.

    Enter RFIDs. They're cheap, there portable and they can be owned. A person simply purchases the RFID for a work, and then that RFID is scanned any player in any format before the work can be played.

    Taking your mp3 player filled with music you own on vacation? Simply wave it over your box of RFID tags, and viola! The player knows you are legally entitled to play the songs you copied onto it.

    You could make as many perfect digital copies as you like of your CDs or even DVDs and it wouldn't matter. As long as the player is able to check the RFID tag for ownership, the media will play.

    Granted there are some problems. As they are small, RFID tags would be easy to lose, and all sorts of issues come up when you consider online purchase of media where physical objects like RFIDs can't be used. But it's an idea, nonetheless.

  • 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 [phidgets.com] 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).

    ...are there ANY real hackers out there?

    And no, I'm not talking about 1337 case modders or overclockers. I'm talking about real hackers like this one. Doing hardware and software hacks that are done just for the sheer joy of doing them, and can be done because they CAN.

    Mod me down as flamebait if you will. This is something very cool. Who the hell cares if it's practical. Neither is a machine that can turn ordinary dog biscuits into india ink. But the hack value is enormous.
