I like this, reminds me how the old valve tech was wired before pcbs were used, its olschool wirring, simple and works great, also can be used as a low voltage meter... great work either way really liked this simple build well done 👍👍👍
Simple ... Top amazing ..👍👍🙏
Indonesia..
no need to use zener diodes here.
the circuit works/use due Voltage doubler at input
You are right it could be any diode with a normal voltages drop. The design works because each diode is cutting out about .7v.
Todo muy bien! Pero el código de colores está al revés.
좋은정보 감사드립니다
Good news thank you
An actually good video by American Tech, what is this world at this point
Excelente proyecto me parece algo genial muy fácil de hacer no es tan difícil pero gracias a usted lo pude lograr 🙏 un saludo muy especial desde Colombia D.C en chiriguaná Cesar tierra del cantante Gali Galeano. Gracias brother por este video está excelente repito excelente
Hello Friend. first I want to congratulate you on the projects, I've already watched a good part of your videos. If you can, could you tell me about VUmeter? requires minimum power? I want to use it in a project that has a very low power less than 1Watt. It will work ?
Very good tutorial, excellent vu meter without plate, my question would be how to put a potentiometer to regulate the sensitivity and how to make it electrical so that it works with led strips?
You'd need a transistor for each LED strip, and a separate power source. The transistor base would be connected to the plus pin (anode) of the LED through a 1k resistor.
To power the LED strips from the wall, you can use thyristors controlled by optocouplers.
nice little project. lots of information in related videos. thanks
Отлично, наглядно-ЛАЙК. Жаль не знаю английского.
You are king of the kings!.
Thanks for posting and keep up the good work!.
Interesting I will try to make the circuit thanks for the information greetings from Piura Peru
Hello sir your vu meter via LED very good design and clearly sighted...thanks
please explain why using zener diodes, i see they are forward biased so why not use simple diodes ?
He can also put only the LEDs in series because also LEDs have a voltage drop
American Tech projects are always extraordinary
As well as utterly useless. :-))
@@taunteratwill1787 😂😂😂

I would put the leds in the opposite order, and the capacitor should go to the back.
The Red light must be the last when sound clips no the first one 😁
That's what I was thinking. I'd reverse the color order
@@davidabraham1969 Great mate 😁
Matchetto yes,
I would make two of them. Plus maybe run more lights. Yes *Red would be the last one..
And the caps should be orientated either backwards or flat to put the lights (meter) in a practical location where it can be seen and enjoyed. Like in car audio (the dashboard) or a home stereo.
I made and its working

VU meter ko banane ke bad kya use directly amplifier me speaker ke satha chalayenge kya?
Aur ye 6000w ke Amplifire me kharab thodi hoga?
very very clean and good uv meter,thanks for it man
Excellent project.
And you also changed the sound track ... wonderful :)
Vvvvvvvvvvvv good 👍.Asif from dunyapur Panjab Pakistan
Kya ye small 5V speaker 🔊 ke saath chala sakete hai 5V ka zennar diode lagga ke
So where is the microphone
Thank you so much American tech♥️♥️♥️♥️🔥🔥🔥
Very nice and amazing bro 😍😍
You are wonderful, Greetings to you⚘⚘
ic is a collection of several transistors, transistor is a collection of several diode. so it is............... hahahaha
Not really.... An IC - Integrated Circuit - consists of miniaturised electronic components in one form factor 'chip'- not just transistors, but other components too - resistors, caps, diodes and not several, but hundreds or more, of transistors. A chip containing just transistors would be a - 'transistor array'.
Nice electronic circuit
Wow,,,,,,thank you for a very clear tutorial
This is the really american tech! Good work!
Montei um desses, não durou 5 segundos, foi só erguer o volume pra ver se piscava até o último led...o mesmo não queimou mas parou de funcionar.
As an added bonus, this same circuit could be used as a Low Voltage volt meter. ;-)
Has different voltage drop.
Good and nice
Very nice and simple video, sir agar zayada LED lagani ho to bhi capacitor ki yahi value rahegi?
Wow , very reactive 👍👌
Вообще то красный цвет должен быть в конце. А белый первым.
It's simple and useful~
It is very nice to see a job so well done and clean. I really liked the video.👍🏻
very nice project...i replicated it too but i need highr sensitivity... how i can make this more sensible cuz i am using it on a smaller speaker
Thank you for a great video. I would like to know if it would work if I put 10 more LEDs so there would be 4 at each point. I plan to use a 20 watt amp to run 4 of these. One in each corner of the room where our kids hang out with their friends. Space the LEDs apart and put them in white plastic pipes. The kids like to gather at our house so I will fix it up for the new years. God bless.
Hi. Nice job you did but I want to ask how much power it can handle or can you explain for each diode can be like from here is 10 wats from here to here is 20 wats etc... or can you make form for like 4 ohm speaker 100 wats amplifier? Thanks.
Wow 😲 you tube channel video 👍😂
Super cool..! How many watts do you think that set up couldtake ?
wow, very good work
Só faltou o esquema de montagem do circuito pra não inverter as polaridades...pra quem tem noção é facil.
Gostei do seu vídeo Parabéns 👏🏼👏🏻👏🏿👏🏽
Eu queria que vc faz um vídeo Led da Knight Rider (Super Máquina)
Ya it's Work thanks
Big up good work 👏🙏
Parabéns. Ficou lindo ficou pode ser ligado em potência de som 1200 w da wattsom elas não vem com v.u
Show de bola amigo. Gostei
Es posible incorporar mas led, hasta cuantos
Wow very nice.
So beautiful 😍
Bello ! Ma perdonami la domanda, ma non necessita di alimentazione? Va collegato direttamente sulla cassa?
Thanks!
So as far as the electrolytic capacitors go.... Is the favlue really Important? Like let's say I only had 470uf or 47uf...how crucial is that value and what role does it play in the circuit? I wanna start building modulation meters for my rf amplifiers but I wanna know a little more about this circuit before I include this in my options. Any help is appreciated
I honestly don't think you need it. Fairly sure they are doing some sort of filtering. You also don't even need the rectifier if you are using a biased signal, or really any audio signal above 60Hz. Since the human eye can't really see changes quick enough above 60Hz (where most audible frequencies are 20Hz - 20kHz, so close enough), we can probably simplify this circuit to only be the LEDs, audio input, and resistors.
I built this circuit without them and using 3.5mm headphone jack as input and it was fine. Note that I am not using amplified speaker level as input!!
very good, friend!.
Если это индикатор уровня сигнала, то цвета светодиодов снизу вверх должны быть в обратном порядке, а не так как в видео. Но всеравно прикольно.
Это просто цветомузыка , анализатор частотного спектра так не собирается
Can i use 40 led's? Which sequence can i use them, Green, Blue, Yellow and Red?
I tried this and it works with my 15W amplifier, but it's not sensitive enough, it only lights up the first LED when volume is at 75% at amplification at maximum
Добрый день, схема для печатной платы есть?
Good video .
Loves from India.
Hi
What if i play music at low volume or very high volume? Will it respond as same.
No... because what is happening is that the diodes thats goes upward with the LEDs has a voltage requirement so therefore if you want to hit the white more often you increase the volume if you want to barely hit the red... decrease the volume till that happens...
You need smarter components so that it can auto gain the output for the different volume inputs.
Bro tumne capacitor kaa positive or negative ek saath soldiering kiya tha yaa phir positive sirf
Very nice thank you
Bro, how do i make this but with 3 in line led instead of 1 line yours? I would love to make it but didn't know how to make it with 3 in line LEDs 😔 I've been searching for tutorial videos like this but with 3 line of led but found only 1 line led like your vidoes 🤧🤧
Hey man, good night, I really liked the vu led, I would like to buy one made, you sell one for me...
Cool idea👍
Very good.. 👌
This is called 'psychadelic light'.
Nope. It's a vu meter. Or a modulation meter.
What u said is a term used by hippies lol
Nice voltage Control.
if I want to make it with 20 LED lights do I just add another ten resistors and ten diodes?
20 V zeners x 10 you need to put 200 V to light up that last LED?
No, the diode drop voltage is ~0.7v
So it means that we can use 1N 4148 diode, right?
@@lee68 yes but you need an audio amplifier, for lighting up the last led, you will need ~10v( 0.7v *10 +3v), audio output from a mobile phone is ~200mV (this means the video is fake but the circuit may work with an audio amp)
Very easy vu circuit
There is a mistake with resistor value because te voltage needed to light up a led is different for each colour, then you need a different resistor value for each colour.
This would cause a minor difference in led brightness thats all.
Suuuuuuuuuuuuuuper work bro
Top work suuuuuuuuuuuuuuper, Kerala , India.
From India. Brilliant bro
Meeeeeee toooooo indian

Wow 👍🏻👍🏻the best
Excellent work dude👍👍
How could you help me, I did that same circuit but it doesn't turn on all the LEDs, it only turns on one. Near the capacitor my capacitors are 25V at 470 uf and my resistors are 56 OHM and my LEDs are white, what can I do and my horns 40W and 9ohms
For fun is OK,for professionals not ok
Hey man, good night, I really liked the vu led, I would like to buy one made, you sell one for me...I want it with 4 red 3 yellow and 3 green LEDs okay...
Kya hum koi bhi colour ka led laga sakte hai
If i want to have a slow response, so leds on off more slowly, can i do this by changing capacitors value?
Good question, did you tried this? Any results?
No you would have 2 add caps in parallel with leds to slow it.
Can i use this one for 3 watt amplimini ?...
This is too good.. does it affect sound quality in any way?
no
Hello, what is the role of the capacitors and don"t they modify the global impedance of the speaker?
let say that nearly half of the power is going to this VU, if it suddenly blow of as so the speaker will blow after.... & about the cost of 9 20V zeners...
Nope. If you're throwing more out of your amplifier than what your speakers can handle, you've got a problem with or without this VU meter. Second, no where near half the power will go to this meter. This won't even be using a watt out of the possible 100 watts going to the speaker. Third, zeners across an amplifier output could prove to be disastrous to the amplifier: 1 watt zener - possible 100 watt amp output - zener overloads and shorts - amp overloads and blows outputs. Huge repair or junk amp all for the cost of some zeners. No thanks.
@@Pulse87dotca ???,
@@Pulse87dotca what ever the power going in this "passive VU" I will never use ore build it sorry, I make préamps and sounsystem gears, so what ever when you blow a speaker in the face of 300 people they all end with a hyperacusis ore even deaf.
@@CyrusBrinkworthRAS I would agree you shouldn't build one. I would say you shouldn't build any sound system gear if your system designs could blow their own speakers. It isn't the blowing of a speaker that would cause hyperacusis or deafness. It's the dangerously high volume levels from using an overpowered amp for the venue and people too close to your poorly matched speakers. "when you blow speaker in the face of 300 people"?? *When*? There's no excuse for blowing a speaker or making people deaf at any public performance. That said, a passive VU powered off the speaker cables is pretty dumb for a concert sound system. I'm a component-level electronics repair tech and a very competent front-of-house engineer. I've never blown a speaker, or made anyone deaf, even with a 1,000 watt sound system.
@@Pulse87dotca 10years of soundsystem, all in 2homs never and any probs exetp ones, the DJ played some dubplates acetates that was really bad, and if I didn’t cut it of it would blow some hears (the VU was clipping) maybe we misunderstood etch others? and there are sound system that do not know about "mixing" and sonorisation so, they catch fire & more, and next day=head hake ...
Beautiful led play musik.
для экономных сойдет, хотя лучше уже делать либо на 3914/15, либо на микроконтролере - уровень и качество в использовании намного выше!
В 90 е были двухкассетные китайские шарманки у них диоды стояли по кругу на передней части тоже по такой схеме были
I saw it well.
I'm curious. Will speaker output power decrease?
No.
Obviously
Why is the green lamp stronger than yellow?
Simple concept, i like this.
Wow super iam surprised
Big Question Can you do more than one row say 20 row, if so do a vid on that? Not the led strips.
EXCELENT PROJCT
