No web page,  but a little description here.  It has changed quite a bit from the original description.  Now uses TAOS color sensors.     Suppors Melexis IR thermometer chips.  Has 16 bit A/Ds.  Processor is an ATMEGA 1284.  The control program is based on Lady Heather.  Besides LEDs it can also charge/discharge/analyze batteries,  measure power converter/supply efficiency, etc

BTW,  the PWM sensor is a silicon phototransistor with not much blue light sensitivity...
