Xronos Clock platform is extremely hackable, and not just when it comes to software. Recently my good customer William P. designed several versions of enclosure modifications. In this one, he added GPS receiver to get precise time from GPS satellite. Here's a version of acrylic case that also uses different buttons. And finally check out this funky bamboo case! William is also a very good programmer, and he helped me fixing some bugs in the firmware and also he's the person responsible for several improvements. In fact he branched out his own version of Xronos firmware, which you can find here. If any of you made some mods of the clock, drop me a line, I would love to write about it!
I know has been a very long time since last firmware update but rest assured, I haven't stopped squashing bugs and adding features :) Very important note! If you are using Arduino IDE to upload code, it only works with version 1.0.5. I've yet to port it to latest (1.6.x). You might notice that I jumped few sub-versions, that's because I've been updating firmware but not releasing it to public due to some lingering bugs. I wanted to iron out the kinks first. Most of changes are backend improvements to the code, and a lot of changes to the radio code. I've been working hard getting weather sensor to work, unfortunately it's still not ready for prime time. Anyway here's list of changes in V2.13: Rewrote most of the Radio/RFM code (parse sensor battery values, etc.) New Menu option to Reset firmware to factory default. Make sure you cold boot clock after using it (unplug/plug back power). Faster Autobrigtness changes. Fixed bug in sayTemp function Added integer handling for EEPROM data Re-organized code to make it more readable. New Firmeware is available at usual place, under Techincal Data.
