Sunrise Alarm Clock

Alarm clock with ramp-up light and music to get you out of bed on cold winter mornings

Similar projects worth following
A simple alarm clock build that wakes you up with both music and light. Each of the three alarms can be enabled for a specific time and day(s) of the week, and lets you configure how fast the light and music ramps up. Auto-off after 2 hours allows you to fall asleep to ocean sounds, Finnish Death Metal, or whatever else makes you sleepy.

The design is inspired by Japanese lanterns, although the methods and materials are not authentic Japanese woodworking.

I'm getting a little Frank Lloyd Wright vibe from that. Nice work!

Thanks!  The electronics are much uglier than the case.  ;-)
