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. http://processors.wiki.ti.com/index.php/EZ430-Chronos , http://tideals.com/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.One of the models has 433MHz frequency which can, for instance, allow you to interface with many remote controlled devices (garage door).On the link above and on youtube you can find a ton of videos with demonstrations.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 :)
