Show HN: Our Hackable E-Paper Watch for iPhone and Android
Texas Instruments was selling the eZ430-Chronos for $25 the other day, it sold out. <a href="http://processors.wiki.ti.com/index.php/EZ430-Chronos" rel="nofollow">http://processors.wiki.ti.com/index.php/EZ430-Chronos</a> , <a href="http://tideals.com/" rel="nofollow">http://tideals.com/</a><p>It doesn't have bluetooth so this watch has an upper hand, but the chronos has a data transceiver for firmware upgrade, communication with health monitors and interfacing to the PC through an included RF dongle, along with xyz accelerometers , pressure for altimeter and temperature sensor. It's completely programmable with a provided IDE or msp430-gcc if you feel so inclined.<p>One of the models has 433MHz frequency which can, for instance, allow you to interface with many remote controlled devices (garage door).<p>On the link above and on youtube you can find a ton of videos with demonstrations.<p>I managed to scoop one for me and posted the daily deal on HN a few days ago, but it didn't gather much interest :)
