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 👍👍👍
You are king of the kings!.
Thanks for posting and keep up the good work!.
Wow , very reactive 👍👌
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 ?
wow, very good work
very good, friend!.
Wow,,,,,,thank you for a very clear tutorial
Simple ... Top amazing ..👍👍🙏
Indonesia..
An actually good video by American Tech, what is this world at this point
Big up good work 👏🙏
Projeto das antigas 👏👏👏 muito bom.
Excellent project.
And you also changed the sound track ... wonderful :)
Show de bola amigo. Gostei
American Tech projects are always extraordinary
As well as utterly useless. :-))
@@taunteratwill1787 😂😂😂
Interesting I will try to make the circuit thanks for the information greetings from Piura Peru
Very well done!!
Todo muy bien! Pero el código de colores está al revés.
very good thank you
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.
Nice. Thank.
It is very nice to see a job so well done and clean. I really liked the video.👍🏻
Отлично, наглядно-ЛАЙК. Жаль не знаю английского.
Simple concept, i like this.
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.
very very clean and good uv meter,thanks for it man
Top ❤️👍
좋은정보 감사드립니다
Good news thank you
As an added bonus, this same circuit could be used as a Low Voltage volt meter. ;-)
Has different voltage drop.
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.
It's simple and useful~
Very nice and simple video, sir agar zayada LED lagani ho to bhi capacitor ki yahi value rahegi?
uauuuuuu, best ideas!!!
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
MUITO BOM ESSE VU.
Dioda zener ganti 4007 iso gak yo ?
Вообще то красный цвет должен быть в конце. А белый первым.
Good video .
Loves from India.
Tengo un problema, armé el circuito con la mitad de los leds y su correspondiente cantidad de resistencias y diodos. Pero dos leds de ellos trabajan a 1.5v mientras que los 3 restantes a 5v.
entonces los leds de 1.5v no iluminan. Todos tienen la misma resistencia. Que resistencia debo ponerles a los que no encienden?
Elinize sağlık 😘
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.
nice little project. lots of information in related videos. thanks
Nice electronic circuit
Cool idea👍
Very good, super
en caso se hacer varios. como hago para que capte frecuencias mas bajas o mas altas. tengo que ir variando de capacitor
in case there are several. How do I get it to pick up lower or higher frequencies? Do I have to vary the capacitor?
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
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!!
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?
excelente work bro!!! other favorite + ^_^ Thanks for idea.
Good work
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
I would put the leds in the opposite order, and the capacitor should go to the back.
I'm going to try it
Bro tumne capacitor kaa positive or negative ek saath soldiering kiya tha yaa phir positive sirf
Perfect!!
Nice project awesome😁😁
You are wonderful, Greetings to you⚘⚘
Hello sir your vu meter via LED very good design and clearly sighted...thanks
Excellent work on this💪💪💪👌👌🤘🤘👍👍👍💓💓❣️❣️
Nice and clean!
🌟🌟🌟🌟🌟
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
Pode aumentar a quantidade de Leds
Muito bom ok, nota 10 OK
tem como disponibilizar o esquema de montagem por favor
I saw it well.
I'm curious. Will speaker output power decrease?
No.
Obviously
woah awesome LEDs
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
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
Помнится такой эквалайзер стоял раньше на магнитофонах двухкассетных😉
Ага. Только это не эквалайзер, а измеритель. На китайцах в начале 90-х стояли сплошь и рядом. И выглядели эти магнитолы, как новогодняя ёлка.
Thanks!
LOVE THIS!
Excellent work dude👍👍
The register is from Decide which side is connect...pls tell me
how much voltage is required by it to run?
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'.
Very good 👍
What is the title of background music used in this video??
And previous videos??
Es posible incorporar mas led, hasta cuantos
Can you make 4way traffic control system project? It will be helpful
Thank you so much American tech♥️♥️♥️♥️🔥🔥🔥
Hello, what is the role of the capacitors and don"t they modify the global impedance of the speaker?
Nice voltage Control.
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.
Прикольно! А как рассчитать ёмкость конденсаторов для разных частот? Подскажите пожалуйста! Nice! And how to calculate the capacitance of capacitors for different frequencies? Please tell me!
Mantap :-) :-)
Beautiful led play musik.
if I want to make it with 20 LED lights do I just add another ten resistors and ten diodes?
Wow very nice.
Muito bom Joao alves
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 ...
qual a potencia minima para exitá-lo??
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.
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
thanks
Kya ye small 5V speaker 🔊 ke saath chala sakete hai 5V ka zennar diode lagga ke
Gostei do seu vídeo Parabéns 👏🏼👏🏻👏🏿👏🏽
Eu queria que vc faz um vídeo Led da Knight Rider (Super Máquina)
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
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.
Super cool..! How many watts do you think that set up couldtake ?
Can we use this with 12 v out put
