This flasher circuit consists of an astable multivibrator with the frequencies given by the capacitors. The circuit is from 1965 using light bulbs, but LEDs can be used. Power comes from 4 batteries.
This conventional LED effects circuit uses integrated CMOS. Today we can achieve the same effects...
