Stateless clock with instant time sync and with sensors integrated with vera from micasaverde

thingiverse

This clock, found at http://www.thingiverse.com/thing:159417, is stateless – it doesn't require manual time setting or a battery for continuous operation. It syncs the time instantly upon power-on and every eight hours. Aside from telling time, this clock also functions as a light sensor and temperature sensor. Check out the photos to see how these sensors look inside Vera and on a smartphone. For a demonstration, watch this video: http://www.youtube.com/watch?v=-3a9ePBjax8. This clock is installed in a bathroom and powered by the same wire as the light, so it doesn't need constant power like other clocks do. However, its instant sync feature makes it superior to wall or battery clocks. Discussions about this project can be found at http://forum.mysensors.org/topic/1002/simple-mysensors-clock/2. Just remember to position correctly before slicing to avoid the need for support.
