Actually, it is. Old VU meters (both in LED form and analog) were actually linear meters. That's why you see things like -20 then -14 then -8 and so on up to 0, then +1, +2, +3. The steps for each dB spread out when looked at this way, but it is typical. You are also correct that a '3915 gives even 3dB steps. Interestingly, you should look up the '3916 as well as that is the official "VU" chip. It tweaks the linear steps to give as exact dB numbers as possible, while still having the same "feel" as the '3914. IE rather than being -8.4 dB or whatever, it is -8.0 or whatever.
@LFTRnow Yes, you are right. So this one needs a logharitmic dB scale behind LEDs. I've built many, mostly 3915 and 3916, cascaded for better dynamic range, and one special 2×60 LEDS on chips, 2×60dB range.
That’s nice but those bargraph ICs are pretty much unaffordable for much of the audience if you want to buy the real parts. An LM2901 or LM339 comparator is cheaper even though you have to buy three of them. And it goes past eleven (12 leds) :) Even an LM2902 or LM324 will work well as a comparator in this application. With additional external resistors needed to set up a comparator chain, it is still cheaper than the bargraph IC! And that is naturally suited for a peak-tracking reference instead of a fixed reference, so that the display stays lively independently of the audio signal level.
4440 dual ic amplifier me 12 volt dc pe 10 led red + 10 led green (20s led light for 3 mm led light) ko konsa resistance lagega bhai. 1 k resistance pe only 10 red or 10 green 3mm led jalti hai bhai
Das war zu DDR-Zeiten der A277 den kann man im Punkt und Bandbetrieb betreiben hatte hinter den LEDs noch eine eine Transistor Stufe mit einem pnp und npn Transistor pro LED und einem Triac damit hab ich 200W Lampen angesteuert ja da gab es noch keine so schönen LEDs wie heute aber trotzdem eine tolle Schaltung

,
OK
Great Circuit, Thanks!
Seems that your soldering iron is leaking a bit of mains to light up the LEDs....
Yes
I also have
It does that for me as well

Amazing..... 😊
The soldering iron is leaking voltage, watch the LEDs light up slightly when soldered.
the Tip of a soldering Iron Is Grounded, so the Iron on One pin an your hand on the otheronegenerates a little ac Voltage
How to fix that
Me pasa lo mismo, pero mi soldador no está conectado a tierra ya que solo tiene 2 clemas el conector de 220V.
Aaaaa gracias Hermano,ami siempre me pasó lo mismo y si cómo ustedes y ustedes vieron cómo se prendían los led,a mí me a pasado exactamente lo mismo
वाह भा इ का बा त है 😊🎉2022 का vidiyo ❤
This is not a VU meter. This is a flasher at the most. Use LM3915 instead of LM3914 to obtain a 30dB range, 3dB/step VU meter-like show device.

Idk wat I’m reading but I know those things
No pin 2 is amazing - I never knew that would work with LM3914; always a ground in other circuits? Very clean design!!!

The best i noticed in your work is that the beauty. Really you have talent to represent your work beautifully
👌👌super

The LM3914 he uses is like $5 new and 10 for 10 on ebay. The shitty speaker amp is more expensive.
@@iyatemu “10 for 10 on eBay” - yeah that’s not a TI part you’re buying for a buck lol.
@@absurdengineering maybe, maybe not, but a 3914 isn't "unaffordable"
Awesome! The building of these basic electronic devices is so amazing and vital
Led is little bit glowing
Thank you
Congratulations, you are so quick, accurate and skilful !
I love how their soldering iron is lighting up the leds
This is perfect for me I’m an engineer and I like lights and music
Bro's mind is from other galaxy💀
Hii
Circuit achha h pr kam volume me vu miter itna chal raha h to full volume me to sari led ek jaisi hi jalegi.

Waaah yrr
Can I see the circuit diagram pls
niec vido
Good job👍
TQ sharing
Cool authentic sir
Super 👌
Agar ye 5 v pr chale to bahut kyoki 5 v aasani se mil jata h,aur 3.5 v muskil hota h
Your message is high fast why so hurry .
How is your speaker working with a earphone wire? 😮
Hi nice work 😊
Can we appreciate that the LEDs light up when he touch them with the soldering iron?
good
Vu meter connection don't give direct to speaker , we have to give lineout
Super
Super great video
🙏🙏👌👌
How did the soldering iron leak voltage?
Fr
Ic name please
❤❤❤❤Good ❤❤❤❤❤❤
Vera leavel💯🔥😉
Ic number.? 🙄
Nice bro
Very great
Nice music
out of standing so nice
Hello sir ekk mere liye Bluetooth se chalne wala amplifier per aise Jaise aapane light banai hai ISI tarike se base per bajane wali light kaise banaye
❤❤
Inn ente like ee brohkk you made me happy😘😘
👍👍👍
I saw the leds faintly lighting up while soldering them... maybe your soldering iron needs grounding
super bro 👍👍👍
Amazing🎉
❤❤❤❤

Das war zu DDR-Zeiten der A277 den kann man im Punkt und Bandbetrieb betreiben hatte hinter den LEDs noch eine eine Transistor Stufe mit einem pnp und npn Transistor pro LED und einem Triac damit hab ich 200W Lampen angesteuert ja da gab es noch keine so schönen LEDs wie heute aber trotzdem eine tolle Schaltung
а СЕЙЧАС В АМЕРИКЕ ЖИВЁШЬ ?
Nee in der ehemaligen DDR sprich BRD
❤❤❤❤❤❤
Nice
The track from dynamics please
What amplifier board do u use bro🇵🇭
❤❤❤😮😮
Op
😊😊
People before the breadboard was invented:
Very nice telent 😮❤
💔💕❤️

It's possible just because of semiconductor, A chapter in physics Semiconductor and electronic devices is best to understand all these electrode
Nice 🎉
Nice
Your soldering iron has leakage
Nice bro ❤
Ah classic LM3914 ic! Good ol hobby days! 😅
Música muito boa acentou com vídeo
Gajab yaar 😮
Great job 💪💪💪
Good complete circute
🔥🔥🔥
Wow👌✌️
Nice 🙂
manda o esquema
Wow flash led at last something new
Are vah gajab❤❤❤😮
Amazing ❤❤❤😮😮
Can we do this with arduino uno?
Hi
Creative video, thanks :)
It is so beautiful 😻😻😻
Jo bhi meri tara comment padhne aye O like karo
дебиллл
why did the LED glowed while soldering 🤔🤔
👍👏👌💖
How!!!
Please add voice for guidence instead of background music.
Thank you.
Очень классная поделка - буду себе делать а музыка вообще божественная..самая лучшая - жалко урезали.
а с ТЕЛЕФОНА ГОВНО ЗАЗВУЧАЛО
Fantastic 🎉
brat davay

Bro which is that speaker board
I don't know if anyone has noticed, but if you have, the blue light comes on when connecting the lights together So when you solder
Bro your soldering skills are awesome ❤
Is this flash type Analog to digital converter?
Ever heard of a breadboard? Or PCB way? We are not in the 1950s no more so wire's and mess isn't needed any more!!
Nice 👍 I like these wire lead constructions. So artistic.
Nice ❤❤
