VU meter only with transistor | Without any IC

In this video, I've shown a VU meter using transistor BC548 and BC558 and with Zener diode 1n4148.
Required Components:
Resistors: 1 KΩ, 10 KΩ
transistor: BC548, BC558
Capacitors: 47μF/ 25v, 1μF/ 25v
Diode: 1n4148 (Zener)
Miscellaneous: LEDs.

Your soldering skills are great. I would love to see a video tutorial of making solder tracks on the perfboard circuits you build.

[@EEWave]

Sure, I'll try to make this.

[@jstro-hobbytech]

You are an awesome teacher. Are you self taught or educated in electronic engineering?
That would look awesome in a thin frame with the light difused using tracing paper under the clear plastic poster frame material from a craft store. You could make like 20 of them for under 20 dollars. Thanks for the idea. The frames are garbage quality but the parts can be reused perfectly for multiple projects like this to make them look like they were built professionally.

Hey, you did it, good job.

[@xmenken1]

Very interesting electronic experiment.

[@garnoni]

Amazing job!

[@vsnova3795]

I am going to make this project love it but can U explain about audio settings where to connect ground wire??
Thank You!!❤️

[@EEWave]

All the ground (Audio signal and power supply) should be connected together.

[@Tom-ct4jg]

First, nice videos by the way, helps alot

[@EEWave]

Glad you like them!

[@Ors56gaming]

Good bro

[@leddanushka1828]

How to voltage

[@natobar2555]

top muito bom!

[@josephpascual214]

How about schematic diagram Sir..

[@sergiomariano4675]

muito bom gostei

[@bilaloubaddi8153]

nice video

[@EEWave]

Thank you...

[@jstro-hobbytech]

What gauge is that solid copper wire?

[@joaoalves2281]

Porque usar 12wts pra vender os led.

[@ad-we5cf]

Can i replace 1n4148 with 1n4007?

[@bogdankalas1318]

1n4148 its a not ZENER diode!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@Mildelectronics]

Yes. It switching Diode

[@rodneymacwan2527]

4148 is not a zener diode. It is a signal diode.

cara masangna kumaha?
