The star is about 35cm across and designed to be displayed indoors in a window.
I originally created the star three years ago using a 16F872 controller. The original version worked ok - but had no spare memory for adding more features.
This new version uses a 18F2620 because I now prefer the 18F series and decided it would be a good general purpose 28 pin chip to use. It has more than enough memory (64K) so I can add as many features as I want now.
(It should also work using a PIC18F2525 instead if you find it easier or cheaper to obtain)
Since, I made the first version, brighter LEDs are now available and cost is much lower - this project currently uses a total of 60 comprising of 25 Blue, 15 Green and 20 Red.
