Circuit diagram No Transistor no IC LED VU Meter do it yourself at home with me

I made this video because too many people asking me for circuit diagram or schematic diagram on this video: https://youtu.be/KH5THY7sC7I

This circuit doesn't need special power supply, no IC and no Transistor needed, just connected this circuit directly to Speaker or Transducer.

Component list:
- 9 pcs 3 volt LED bulb
- 9 pcs Resistor 470 ohm or 560 ohm (0.25 watt or 0.5 watt)
- 1 pc Resistor at least 4.7 ohm (0.5 watt) resistor value depending your Audio amplifier power
- 2 pcs Diode 1N4007 or 1N4001 or 1N4002 or etc
- 2 pcs Electrolytic Capacitor 220uF/25v or 470uF/25v
- 8 pcs Diode 1N4148

Friens, this video is how to make vu meter without any ic without transistors without pcb and without special DC power supply.
