American guitarist and studio recording engineer here, Love the content, always looking to increase understanding. the concept at 9:05 with the resistor transistor and potentiometer wiper center is super interesting to me, but it seems in general could this project be done way lower volt less resistances? maybe 9 v, but I presume you'd just want to use an IC chip at that point? inspiring work! would love more WHY information and maybe schematics/diagram, link you have a gift here. Thank you!
Welcome friend. For 9:05 it just a very simple driver and convert audio signal to the voltages signal. Every 1n4148 diode need 0.7 volt to start working, thats why this circuit need minimum main voltage 28 volt so that all LEDs can light up at the maximum peak. If you use 9 volt, so the LEDs that lights up is only up to the 12th LED (9/0.7) when at the maximum peak.
After I've got succeeded making Stereo VU METER-LED with single IC LM3914/5/6 (you can see on my another video), and now I'm in experiment to develope "Peak hold VU METER-LED" with single IC LM3914/5/6.
@@moristo awesome replies man will be following along. Doing my own little DIY kit I purchased here, honestly just worried about the size of the connections I need to solder because I need precision!
@@moristo Yes, just worried about my soldering skills but, setting up a nice work station is the first step. I'll let you know how my project turns out.
i would like to make this with line level or headphone level. on usb voltage with a normal usb battery pack. do you know a video or a diagram to make it? the american db tracker costs 65 euros lol. if i can build it myself for the half price then im happy
@@Lamster66 Based on your comment I feel that you know about the forward voltage of a diode, so I think you know abaut how much voltage for each LED step to light up. The resistor at each transistor base will limit the peak base to emitter voltage in each transistor. For a comparison of total component prices between using IC and Transistor, you can find out yourself based to the component price on the marketplace. Please see my video Dot & Bar mode VU Mtr LED without IC.
Tegangan 24 volt, minimal arus 300 mili Ampere (0,3 Ampere). Kalau masih tersisa 2 atau 3 lampu LED terakhir tidak nyala, coba tegangan di naikkan 25 atau sampe 28 volt.

@@moristo higher, or lower ohm resistor for 12 to 14v? resistor ohm yang lebih tinggi, atau lebih rendah untuk 12 hingga 14v? (Google translation - terjemahan Google)
Good question, we have to know every 1N4148 diode have minimum 0.62v forward voltage. So to make all LEDs goes light up we have to use minimum Supply voltage with this formula: (Forward voltage x numbers of LED).

Apa yg perlu di adjast @ ditukar apabila lampu led tdk menyala sehingga atas,hanya separuh..sedangkan voleum sdh out buka..tlong ya???
Maaf, pertanyaan seperti ini muncul oleh sebab menonton yang loncat-loncat, sehingga ada informasi dalam video yang terlewatkan.
And which of the videos use the laptop?
Take a look to my video "2 Transistors no IC sensitive VU METER LED"
If a chaser circuit use BD 139/NPN can I use BD140/PNP instead? And do I have to change the circuit?
If you change NPN to PNP, you need to exchange between all Anode and Cathode (including + and - power supply).

Sama-sama.
24 volt DC or above compolsory for 40 led ???
Each Diode average Breakdown voltage is 0.6v, so for 40 Diodes is 24v (minimum), that's to make till the last on all diodes can works.
@@moristo so, 20 LED is good for 12v.
and each speaker can use 20 LED at 12v?
@@jenntek.101 Sure, each speaker can use 20 LED if you make it like that.
By using a capacitor, how can you make the LEDs fade very slowly on and very slowly out and maybe make it adjustable?
Increase capacitor value to make it more slowly. To make it adjustable faster or slowly that will need another potentiometer with special circuit.
@@moristo thank you :)
Hmm, you are welcome.
Will mixed colors work?
I want to use orange and red at the top
Sure you can use it.

Interesting that the meter only responds to the bass frequencies and not the whole audio spectrum?
The signal input I connect to my subwoofer as I have shown in my previous videos, so only bass voice will take effect to the LED light movements.

@@moristo iya mas, maksudnya kan kebanyakan yang 3mm sangat terang, beda dengan yang di mixer build up..

For class D amplifier you have to use more audio filter for the amplifier output so the LO frequency (around 300kHz) can't interfering.
