Blinking Christmas Wreath ornament

thingiverse

Mixup of the Christmas Wreath (Thing 13179), a CD4060BC, 12 LEDs, 8 resistors, a capacitor and 9V battery. Makes a bright blinky ornament (and a great 4H project) Instructions Print Thing 13179 Drill 12 holes of about 5mm at various locations. I chose a pretty even mix of the "balls" printed on the ornament. Push a mix of colored LEDs into the holes - varying them evenly throughout. I used pairs of [ Blue (3v) and Red (1.8v) ] and [ Green (3v) and Yellow (1.8v) ] LEDs on either side of the trigger line. This keeps the voltage the same and allows me to use 200Ω limiting resistors. Using the trigger lines on pins 1, 2 and 15 run at reasonable blink speeds. I chose 5.6kΩ, 10kΩ and 10nF for the clock, but works fine with a variety of values (100kΩ instead of 5.6kΩ for example).
