Introduction: 512 Color LED Flasher (random)

About: Music: my profession for over 40 years... Electronics: my beloved hobby always.

This LED flasher displays 512 colors without the use of a microcontroller. A 9-bit binary counter generates a pseudo-random number and 3 D/A (digital to analog) converters drive the red, green and blue LED's.
