LED Sun Clock


I like sun clocks but the sun only seldom shows up in my office (in fact, never). That's why I build up an electronic version with LED lights. The heart is a ATmega8 controller with a quartz oscillator. Despite that I never soldered such a circuit before, the result is acceptable.

Some steps are documented with a camera. Enjoy.


Simple setup and programming

The ISP is an ATeval board. Cheap but powerful and easy to use.

Attach the ring to the board


Circuit design and soldering

First installation

Sphere build

First construction

Testing the light

Final programming

Mounting the (plastic) jewels and final painting

Final setup

The clock is still running.
