Description

This is a 12" bathroom mirror with two high-CRI white LED light bars built in.

It combines a bit of woodworking with a track saw and CNC machine with some electronics.

The two LED bars were so bright that an additional PWM dimmer circuit had to be added. It uses two 555 timers whose duty cycle can be adjusted with a trimpot. Because of the lighting situation in the room, the left and right sides need different brightness levels so there are two separate adjustment channels.
