We’ve seen our fair share of sunrise simulators, but by far this one is the most polished build–everything from the atomic clock circuit to the LEDs are all packed cleanly in a frosted acrylic case.

Renaud Schleck, the tinker behind the build, describes the guts:

This is an alarm clock simulating the sunrise, which means that a few minutes before the alarm goes off, it shines some light whose brightness increases over time.

The alarm clock is built around a MSP430G2553 microcontroller compatible with the MSP430 Launchpad from Texas Instrument.

It features a DCF77 module which sets the clock automatically through radio waves.
