  • Awkward cache was awkward. [SHIFT] + [F5] cleared it up.

    Nothing to see here...

  • Herm... Then me wonders why I'm seeing part 1 of the My Free Day video...

  • pssst Guys: The wrong video is embedded up there ^ :-)

  • I'm noticing that the pic is broken too.

    But if I recall he basically had just soldered that DigiKey part on the bottom of the board to the three pins next to the Reset pin. (5V, GND and RST.) Prolly isn't too hard to figure out. Datasheet should pretty much give it away.

  • There's a local computer shop just across town that's rather well-known here for having a lot of the "odd stuff", and the SparkFun line would be a great addition to their inventory:

    Computers and More


    350 East Lakewood Blvd

    Holland, Michigan 49424 616.396.5222

    Hobby Lobby is another one that springs to mind, but they are a rather large chain and I'm sure you've heard of them before. :-) (Just consider this my vote for them.)

  • XBees run on the ZigBee standard, which is pretty nifty for most any type of low-bandwith intra-device communicaiton. I'm not aware of anything in the same category as XBee (cheap, easy to use and resilient), but I'm sure somebody around here is.

    You might want to look into the 900MHz XBees if you need a lot of range. Those things can get up to 6 miles (!) with line-of-sight: http://www.sparkfun.com/products/9097

  • That would explain my issues as well.. Trouble is my project is in an enclosure so reset button is nicely out of reach.

    Do you know of any nifty work-arounds in hardware for this?

  • If you are looking for cards that you can set the values of then look into the MIFARE module and tags.

    These tags are set at the factory and cannot be edited later on. The readers are not capable of writing to tags anyways, but there are read/write modules that operate in the 125 kHz range, given the proper tags.

  • Make sure you've set your connection up properly. This module outputs at 9600 baud, not 115200.

    Beyond that it's 8N1N (8 data bits, no parity, 1 stop bit, no flow control.)

    The tutorial steps you through the HyperTerm setup. http://www.sparkfun.com/tutorials/243

  • Unfortunately there is not. The output is the raw data from the tag, so you can convert that to binary and work back up if you need to get different values from various ranges in the card's output.

    (It comes from the reader in hexadecimal format, so it's a fairly straightforward conversion to binary.)
