    Another great project but I do wish you would build them with more permanent power and audio headers. Many people building these would love this. Just a suggestion and doesn't take away from the superb build ideas.

    • @Stefano91ste
      @Stefano91ste  3 года назад +1

      Thanks! Any suggestion is precious to me, I should start building them with microphone, in order to make them completely autonomous

    Salve e complimenti per il bellissimo progetto....sulle casse quindi ci và il cavo blu ed il cavo giallo?

    • @Stefano91ste
      @Stefano91ste  3 года назад +1

      Ciao, grazie mille! Esatto, giallo e blu sono ingresso segnale(giallo) e massa(blu)
      La massa delle casse è in comune con la massa dell'alimentazione del Vu-Meter

    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.

      Hi, it's very strange, try adding a 5K potentiometer on the input, it might solve the problem.

      Hi, I have shared the gerber files for free, and I recommend using JLCPCB for purchasing PCBs (orderable by uploading my file as shown in each video) no one is authorized to sell my PCBs.

    Deduco anche che hai messo in comune il ground di alimentazione ed il negativo del segnale per risparmiare spazio. E' giusto?
