1 1 Christmas Light Display (this presentation repeats every 2.5 minutes) Our 19 th year Over 6000 lights Uses $1.20 of power daily (equivalent to the use of 2 hair driers) Recycle materials content about 75% Lights on 6:00 PM to 10:30 PM from Dec 1 to Jan 2, 2002

2 2 Snowflakes Computer controlled ¼ mile of wire 48 computer outputs 388 lights 816 solder connections Built in minute program cycle

3 3 Spruce Trees Computer controlled with a 68HC11 MCU 3 –interacting pulse- width-modulated light strings that create the “fading” effect.

4 4 Island Computer controlled “Monoliths” in center are micro-controller controlled. Total light elements=840 on 120 display units Holes drilled for circuit boards=1620

5 5 Flowers Each flower has a micro-controller in it. Separate wiring pattern for each flower Total number of lights=112

6 6 Star 1 motor 2 micro-controllers This star is 4 th made in 16 years

7 7 Gate Uses “neon” wire Two high-voltage inverters drive the display
