I’ve updated the popular Lux Spectralis kit! The new Lux Spectrlais 2 kit uses three separate LEDs for the red, green and blue color channels. The circuit still does exactly the same thing (blinks multi-colored LEDs). This will make it much easier to modify for custom color combinations. Check out the Lux Spectralis 2 Kit in the store!
The new PCB is a little bit smaller than the previous version. It uses electroless nickel immersion gold (ENIG) plating on all the electrical contacts, which has its own advantages, electrically, but I did it because it’s more beautiful and contrasts well with the black solder mask.
I simplified the whole thing and reduced the component count. This will make it easier to assemble. You can download your own copy of the assembly instructions.
The kits still comes with a 3xAAA battery holder with a built-in power switch. The lighting modes are identical to the previous version. The price remains the same.
