DWex watch looks for future development

[FlorinC] sent in his DWex Arduino watch, with intentions for it double as an experimenting base. Inspired by the MakerBotWatch, it runs an ATmega328P, DS1337 RTC,and 24 LEDs to display the time. [FlorinC] tells us the (yet to come) case and strap will be similar to Woz’s watch to ensure airport security tackles him. As for experimenting, the PCB contains an ICSP6 and also an FTDI connector for those “other-than-watch purposes”. We’re not all sure what else could be done with a watch; we racked our brains and came up with a compass, but with the source code and Eagle files available maybe you have a better idea?

    Hmm… Wifi presence indicator? Accelerometer? and with some fancy calculations even a speedometer… v=at. It is a watch to begin with anyway…

  2. BP says:

    It definitely needs to be radio controlled! Manual time adjusting is just below a hacker’s dignity.

  3. JB says:

    And before the Arduino haters post something, here is a couple of non-arduino boards. Go develop the same project on these PIC platforms.



    (no, I’m not associated with these guys)

    Cool project. I agree this should be radio controlled. I say that in all my posts regarding clocks :P

    I always wanted a watch that would alert you if your car alarm is set off!

  5. JB says:

    @golddigger50: cell phone module? :D

  6. rob says:

    Cool, now make it half that size.

    I don’t want to ware a belt buckle on my wrist.

  7. pff says:

    Am i the only one who thinks these watches are all stupid and ugly?
    Look at the size of it!
    None of the straps or housings made are decent in any way.
    I guess some people just enjoy looking idiotic

    Time to put in that 1W laser for those James Bond situations…

  9. therian says:

    If you cant find better solution than one which was found in 1800 why bother ?

  10. Osgeld says:

    really therian? how many digital watches were there in the 1800’s? I was always under the impression that they were fiddly fragile mechanical devices, that were hardly accurate unless you were Rockefeller rich

  11. Dave says:

    Thermometer (both ambient and human).


    Light intensity.

    Flash storage.

    Magnetic field or electric field intensity (lighting predictor?).


  12. BP says:

    To all people saying that it’s too big for wrist: pocket watches are really, really cool!

  13. Justin says:

    Tv be gone. pulse oximeter, breathalyzer, blinkey light hallucinatory thing, strobe guitar tuner, tachometer, midi drum sequencer, bluetooth controller, tap tempo bmp counter. Ir secret messaging device, current probe, decibel meter. narrow band spectrum analyzer, rfid read and spoofer. personal data logger.

  14. Justin says:

    Also the battery/charging could be by a novel mechanism. A potato clock for the new millennium.

  15. therian says:

    yes really, a mechanical hand can show more than 12 positions

  16. MGP says:

    Take a look at the Texas Instrument eZ430 Chronos dev kit for some ideas.

    Yea, someone could do a whole variety of things with this if it were outfitted with an array of sensors.

    I, personally, like the idea of integrating some sort of 802.11 module with a TCP/IP stack, combined with a 16/32GB Flash chip for wireless NAS “in the pocket”(yea, I, too, cannot see this as a “wrist” watch)…

  18. fc says:

    This could be on the same board as well:


    Rob, we are working on that (making it half the size).
