An artsy night-light that glows with the phases of a Puerto Rican sunset.


For a few summer months I managed to trick a beautiful blonde dancer into hanging out with me for a while. In my bewilderment I made a night-light as a present for her 30th birthday.

What it does

The sand dollar glows with the main phases of the sunrise (contrary to the project’s name) and looks rad.

What it’s made of

Theory of operation

A potentiometer on the controller board mounted to the rear of the shadowbox cycles through five colors and ‘off’. Each 1/6 of a turn sends the next color in the palette to an RGB LED controlled by a local PWM driver.


Worked like a champ.
