Instructables member Kothe has kindly published full instructions, 3D printing designs, and electronic layouts for you to easily build your own simplified version.

Alarm clocks are cheap and abundant, but they’re pretty boring. If you want to make your own, Instructables user Paranoid Legend shows you how to build one with an Arduino.

You have a timer and clock in just about every single device out there these days, but if you want to build you own, Instructables user GeraldF6 shows you how to do so with a Arduino.

An Arduino and Real Time Clock are responsible for the time keeping and coordination of the LED’s. As you can see in the photo, 2 of the LED’s colors are used.
