Comfort Thermometer display built with 517 individual LEDs

Richard wrote in to tell us about a ‘Comfort Thermometer display built with 517 LEDs’ that he has just finished building:

Comfort Thermometer Display built with 517 individual LEDs and the following microprocessors:
1) PiC24FV16KA301 – controlling outer 36 RGB LEDs
2) PIC16F886 – bargraph and pink LEDs animations
3) ATmega328 – controlling 7-segment display
4) PIC16F57 – rf transmitter and receiver

The bargraph LEDs are current sinked with LM3914 LED display drivers, and current sourced via the PIC16F886 and transistors
