Lux Spectralis 2 Now Available
I’ve updated the popular Lux Spectralis kit. The circuit still does exactly the same thing (blinks multi-colored LEDs). 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 new Lux Spectrlais 2 kit uses three separate LEDs for the red, green and blue color channels. This will make it much easier to modify for custom color combinations. 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.
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.
