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)
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 200ÃÂ© limiting resistors.
Using the trigger lines on pins 1, 2 and 15 run at reasonable blink speeds.
I chose 5.6kÃÂ©, 10kÃÂ© and 10nF for the clock, but works fine with a variety of values (100kÃÂ© instead of 5.6kÃÂ© for example).
