A long time ago i have spotted LED hearth circuit on radio-hobby.org. It was so simple, but effect was really interesting, so i decided to make it. On the Valentine's day i made my PCB and placed everything inside a clock enclosure. And used adhesive tape to keep it in place. It was my first project.
Components:
R1 - 1 MOhm
R2 - 680 Ohm
R3 R4 R5 R8 - 56 Ohm
R6 R7 - 100 Ohm
R9 - 470 Ohm
C1 - 0.1 uF
VD1 - 1N400
DD1 - CD4069B (1561ЛН4)
p.s There is no -9 it's GND
Final::
