This time I bring you a simple and easy to build project, but super good looking.

Features:

• Complete wireless clock with tens of hours of battery (about 3 to 4 days, depending on the brightness).
• Day / Night mode. The light color palette will change after sunset.
• Countdown mode: Set a countdown in intervals of 15 minutes, up to 24 hours.
• 16 levels of adjustable brightness.

It only requires you to print 3 pieces, and follow my Instructables to build the simple electronics: https://www.instructables.com/id/Zen-Clock/

And that's it, hope you like it! :)

And as always, if you like my work feel free to tip me to support more projects like this :)
