Droplet

[Andrew Rapp] sent in this project called Droplet. He’s been doing work with Xbees and Arduinos together and built this little toy. He describes it as “sort of like a Chumby”. It has built in services for Twitter, Google Calendar, News, Gmail, etc. ¬†You can download the full source code and plans on his site. His next planned revisions include possibly running it from a sheevaplug, making a nice case for it, and utilizing the unused pins of the arduino.

    great little project. Keep it up, I look forward to seeing the progress.

    nice i’ve always wanted a chumby but they are just to expensive. keep up the good work.

  3. Regional_Transient says:

    Liked it. How much to construct it? Call me 9163212900

    did he really just post his phone number…

  5. javier says:

    call him and find out

    Remove the ‘Requesting service…’ message, and keep the text on the display until the new text is retrieved!

    Sorry, couldn’t resist. :)

    Hi. Posters: don’t use vimeo. Thanks.

    Also: Java is programming for people who can’t handle programming. Step up to C or ASM if you’re doing chip programming.

    @peter Good suggestion. I wanted some sort of visual feedback that lets you know it’s doing something; the equivalent of the hourglass in windows. Possibly I could just blink a character in the top left corner instead.

  10. Andrew Rapp says:

    @regional_transient The cost breakdown is roughly

    2 XBees $44
    Arduino $30
    Arduino XBee Shield $13
    LCD $12 (ebay shipped!)
    XBee Explorer $20
    Buttons, Buzzer, LED, diodes $6
    Shipping ~$12

    So maybe around $120, but you can reuse these parts in any number of projects.

    @ m4cgyv3r The Arduino is programmed in C. The Java application is the service gateway and runs on a computer.

  12. Tachikoma says:

    m4cgyv3r obviously doesn’t know what he is talking about.

  13. ditty says:

    I have a chumby (for work), they are pretty neat but I really like the homebrew aspect of this.

  14. Andrew Rapp says:

    I thing I forget to mention regarding cost, once you have the coordinator/gateway in place, you can add additional remote displays for relatively cheap. You could use a bare bones Arduino, like Modern Device’s RBBB (~$12) and logic shifters/3.3V regulator in place of the XBee Shield.

    leet speak is for children who are crying for attention. please use normal english alphabetic characters.

    f***in hackaday elite comes and pees all over the parade

    (oh yeah, I’m back!)

    @mcgyver – funny thing is… I found Java to be more complicated then C. Plus mcgyver can run java on a paper clip on chewing gum.

    @everyone else – yes, not sure how much space is left on the arduino but I would think there is enough for some more code. Grab an ethernet chip like ENC28J60 and you don’t need a PC. Maybe a flash chip for buffering and whatever else.
