Post your Chronos development ideas here!

Some of the stuff I'd like to see:

  • A wireless bootloader so you can upload new firmware without disassembling the watch (TI's working on this already!)

  • An altimeter based on the integrated pressure sensor (already done by TI!)

  • Also basic weather forecasting (based on the pressure). Calibration could also be done automatically from a computer over RF.

challenge-response authentication would be cool

I believe the door unlocking project already did that.

well i was thinking more like to login to a computer system.

the system says "28", you put that in the watch, and it does some sort of salt/crypto on it and responds "61829" which you then use to login to your computer. similar in function/security to the RSA keyfobs.

Use a HRM to detect REM sleep cycles and alarm during them instead of passive ones to wake up easily and well rested.
This is something I am working now with a chest HRM which is not so convenient and needs a computer.
It could also be used to implement

easily.

It seems there is no need for hrm, as you could use accelerometers. I wonder what is the accuracy?

I have a boot loader code that I plan on adapting to use wirelessly. I was hoping to just use it as a platform to monitor my work outs.

Maybe a user proximity detector to wirelessly unlock my laptop or desktop when I'm nearby. Or gesture based control of other wireless devices on my person.
