Thank you very much, I don't sell assembled circuits. However, you can find the Gerber files in the video description to buy PCBs on sites like JLCPCB or anyone who accepts that type of file
Stefano!, awesome work! I copied it and it works. But, I would like to have a stronger signal from the mic. LM 386 is a power amp or preamp? What would I have to add or change in order to gain sensitivity in the mic. For example, I have to put the mic directly to my mouth or directly to a speaker to get the meter to move. Please advise. Thank you so much for your dedicated work. James
I just want to make the mic more sensitive so as not have to put the mic directly on the sound or music that I am trying to get the meter (LEDS) to move. Please advise what I can do to make the mic more sensitive. Thank you so much again for your fabulous projects. I am so happy you responded to my letter the last time. Good day to you.
TPA3110 15w+15W Digital Stereo Audio Power Amplifier Board' My question would be, is it possible to tie a vu meter to all Ic-powered mini amplifiers (power stages) loudspeakers? The TPA 311O doesn't go but TDA 2O5O goes nicely. The TPA 15w and an led secular are the last red. Where is the fault I ask respectfully?
My Honor, Sir, I did a vu meter after a video you posted. Tied to the speaker, he goes with a succulent. My problem would be that the vu meter is at a maximum for a small volume. The signal to the vu meters should be reduced. The amplifier is 8w (small). Is it ok to put a poteciometer in or not because of impedance? And how erratic should be kilo ohm. Thank you very much I would be very honored.
Che bello vederti tornare online... ma quanti PCB hai comprato?!?!? :-D Ci sto lavorando anch'io, ne vedremo delle belle... ;-) Domanda: il condensatore ceramico è da 47nF o da 470? La sigla 471 fa pensare alla seconda, mentre la lista componenti alla prima.
Ciao! Ti ringrazio:) Ho provato l’ordine da 20, in futuro li userò per altri progetti, e se sarà fattibile vorrei organizzare un giveaway per fine anno! Il condensatore ceramico è da 47nF, a volte le scritte ingannano anche me
Un giveaway è una cosa che vorrei realizzare da un po' di tempo, ma temo che resterà un progetto irrealizzabile.. purtroppo pare che in Italia una cosa del genere vada "ufficializzata" e con dei costi fuori budget per un piccolo canale UA-cam, e se non ufficializzata ci sono multe salatissime... Ascolta la sua esperienza per capire meglio quello che intendo: ( ua-cam.com/video/OhOF0GeOtdQ/v-deo.html )

Hello, do you think I could easily exchange the Mic with some wires to connect the whole circuit to a Arduino Board and use your VU-Meter circuit for a MIDI-Controller?
Salve Francesco, che tipo di errore ti ha dato? I file gerber sono nell’archivio .rar che si può scaricare dal link in descrizione video. Su jlcpcb.com va caricato il file .rar così come lo scarichi
@@Stefano91ste Salve Stefano, grazie per risposta.. i file sono in formato zip, quando li ho caricati su jlcpcb mi ha dato errore, ti chiedo scusa ma non ricordo il tipo di errore,,,mi pare che non abbia riconosciuto il formato.Però ho provato a vederli con Umancogbr e li vede...non so , forse ho fatto io un errore dato che sono agli inizi. Mi sono permesso , sempre per uso personale, sempre tramite jlcpcb i tuoi progetti ( vu meter e rail led), molto belli. ti posso chiedere un consiglio, che tipo di stagno usi? grazie saluti francesco
Hai ragione in questo caso ho usato uno zip, in altri progetti avevo usato rar.. ma alla fine per JLCPCB è lo stesso. Ho appena provato a scaricare il file Microphone_VuMeter_Stefano91ste.zip caricarlo su JLCPCB ed ha rilevato correttamente tutto. Su JLCPCB devi caricare proprio il file .zip (o .rar in altri casi). Ad ogni modo nel video si vede proprio la procedura di upload. I miei progetti li ho condivisi gratuitamente, a scopo personale / didattico e puoi usarli come meglio preferisci, anche modificarli se ti piace smanettare:) - l'unica cosa che non concedo è di utilizzali a scopo di lucro (ad esempio rivendendo le board o riutilizzandole in video sponsorizzati ecc). Per quanto riguarda lo stagno, attualmente ne uso uno senza piombo e con una piccola percentuale di flussante al suo interno.
@@Stefano91ste ...riprovo piu avanti; come ti dicevo li uso per me, sto imparando e li trovo notevoli i tuoi progetti...grazie di tutto, a presto..saluti francesco
I never recommend Amazon for these items, because they find the same things on aliexpress. From amazon they are still shipped from China (given the long estimated delivery time), but at a higher price. Tested😅 Io non consiglio mai Amazon per questi articoli, perchè si trovano le stesse cose su aliexpress.. Da amazon vengono comunque spedite dalla Cina (visto il tanto tempo stimato per la consegna), ma ad un prezzo superiore. Provato in prima persona😅
Super and super! Dear friend, I'd say so, my friend, but I don't have the right. I like to help you because I've been suffering for a year and I couldn't make the audio signal bigger. I need a drawing with, say, two or three transistors (preamplifier for simple vu meter). I write with a fordito, and I tell you what I know, so how do you understand me? I bought everything from the net ,ready but it didn't work. The vu meter is the simple LM 3915, 1k ohm resistor and that's it! The microphone electret ,condensator .1 transistor. The signal is so good. Megyen but the volume should be weak or high. Help me if you can with a simple solution, I'm starting. BC 547.2N2222.2N39O4.
Hi, I think you are referring to my video in which I explain the OHM's Law (following your accusatory comment, with no explanation about it) video with an example in which with 24v I burn a 50 ohm resistor and then calculate the dissipated power. ( Video: ua-cam.com/video/vKFc_YJJKLg/v-deo.html ).. could you explain it better? I think it is known that I did not invent OHM's Law, clips and explanations were recorded and written by me, calculations are based on the formula V = R x I (OHM's Law). If you are referring to the image portion of the thumbnail, it derives from google images (as specified in the video description, towards the end). So explain to me, what would plagiarism be? If you have seen this same video uploaded on other channels, please link it to me, Thanks! I'm waiting for your answer.

thank you from Morocco .
I tried to do it several times without result, but, thanks to your diagram and component values , it , works very well .
Thanks so much, I'm happy to help you😁

Hi, thank you!
LM386 is a 1 Watt amplifier.. having said that it is great for small projects, but not for applications that require more power

Please advise what I can do to make the mic more sensitive. Thank you so much again for your fabulous projects. I am so happy you responded to my letter the last time. Good day to you.
I have a question!
1.Why did you use the diode ?
2.When I made the circuit, It was changed the Level after 100uF Capacitor. Before the Diode.
Hello Stefano!
Please make a real-time digital clock circuit 89S52 RTC DS1307, I hope you will do it as soon as possible
Thanks you

¿Dónde estaba cuando lo necesitaba como proyecto de la preparatoria? 😞😞
Pero bueno, a ver si lo puedo hacer después.
Por cierto, muy bueno. 😌

- Thank you so much for appreciating my work on UA-cam!
very cool
Thank you!:)
Not sure I understand the pot on the op amp. It adjusts the "sensitivity". But how do you go about calibrating it to be accurate?
What cause you study this knowledge?
Plz reply....
Hi, because I like electronics

A preamplifier with LM386 and microphone should be added on input... maybe in the future I will!
super
Thank You=)
Hello, do you think I could easily exchange the Mic with some wires to connect the whole circuit to a Arduino Board and use your VU-Meter circuit for a MIDI-Controller?
Hi, you could do this by eliminating Microphone and LM386, then connecting the LM3915 vu-meter to the arduino
What changes in the circuit diagram do I need if I want to power it with 5V power supply?
At 5v you can power it without any modification, but no less than 5v

Is this applicable to bread board?
Yes, just follow the wiring diagram
Ole!
can you post a schematic file?
Hi, circuit diagram is in the video
Hi, do you know where to get the LM3915 from, all my sources in UK don't stock this IC
