Sunrise Alarm (Atomic) Clock (fully featured)

[cde 334]

Found this through hackaday.

 

Sunrise Alarm Clock.

 

Uses a G2553 (Programmed via Launchpad)

Uses a DFC-77 Atomic Radiowave Time Receiver for, well, atomic time.

Standard Character LCD (via a shift register) (and pwmed backlight)

Settings through Pushbuttons

Simple Alarm via PWM melody.

10mm LEDS to provide Sunlight (These could/should be replaced with high current 1a/3a type leds imho)

 

And battery backup (with backup status recognition on p1.4 interrupt) via three diodes!

 

A full featured project, though it could use better leds, and unless you are in Europe, a different clock (either standalone rtc, or a regional radio clock source WWV or WWVB in US though I can't find a source for modules)

And a complete schematic would be nice (I think they mislabeled which regulator they use, since they have 5v in on a 7805 regulator (5v out), connected to the g2553)

I like this project as well.  I was thinking of making a Sunrise clock, but:

 

I don't really need the atomic clock receiver.

7 segment display rather than the LCD.

Connect it to my sidetable lamp with a MOC3021 + TRIAC combo to ramp the lamp up rather than having LEDs in the clock itself.
