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?

@soupflood 3 жыл бұрын

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.

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'.

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.

@Pulse87dotca 4 жыл бұрын

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 4 жыл бұрын

@@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.

Neat circuit... But - for a true VU meter, the coloured LED's are in the wrong order. Ideally the order should be something like - green ( < -20 to -7dB), blue (-7 to -2dB), white (Ref - 0dB), yellow (0 to +3dB), red ( >+3dB - 'clipping').

@daoutbox9884 4 жыл бұрын

Each led colour has their own volt drop dictates the least drop would be last on chain - blue and white draw more current. And so on you get very low voltage red leds ect. May be wrong on something here but right elsewhere.
