Make LED color changers…

“It’s nice to have a bit of colour in your house for style reasons, so here are some neat little PCB’s that accommodate a mixture of red, green and blue LEDs giving you the option of controlling the colour they emit. They are designed to fit into standard MR16 downlighter frames for convenience of mounting. Since this page was put up the intensity of common LEDs has risen dramatically and the matching controller project now has extremely sophisticated software that really makes these lights shine.” Thanks Rick!
