Powerful 12v Audio Amplifier using LM358 IC

[@michaelroberts1120]

This designer does everything that should not be done when designing a loudspeaker amplifier. For one, the loudspeaker has a fairly large direct current driven through the voice coil. This will destroy the speaker in no time. Also there is no understanding of how to bias an op amp for single supply operation; the dc voltage at the non inverting input should be mid rail, not vcc. No wonder this thing sounds so horrible!

[@tuhinadribanerjee3214]

Very true, 99% of the crude Class A and AB amplifier diys will destroy your speakers in no time.

[@brandonwilliams-vs9sq]

Thank you!!! Someone had to say it!

[@hobgoblin4202]

358 isnt an amplifier chip to begin with. it amplifies yes. but not meant to be used for audio. detectors and alarms but passing audio will always sound like crap. 386 would be better.

Who attaches a transistor to a power amplifier?

[@varunkoganti9067]

A part of me died when I see people bend the DIP packages and solder stuff on them. Fucks sake afford a perf board. Don't be so greedy about few drops of solder

[@itslife56]

Wow, that sounds like shit! Good job dude.

[@phitrow]

0:16 It is resistor 150K.

[@defuliogames9150]

It's really!

[@azzamwildanmaulana5843]

What do you prefer lm358 or lm324 ?

[@jeanyluisa8483]

Hearing that sound, I really understand why you didn't want to waste a circuit board and enclosures on that amp.

[@shundhem_electrick]

amazing idea

[@meeskees4227]

Can i use an tip35c too to make ik 100 watt or something. Tip35c is 100v 25a 5v base voltage. Is it possible

[@chukwuebukahart9491]

please how did you connect the positive and negative part of the head phone jack

[@inventoseideas3400]

0:16 The resistor is not 100K this is a 150K OHMS

[@karthiksg]

what type of camera you are using to record such, great !!

[@curitosikls8653]

Am I the only one who thinks it's absolutely hilarious that they put a transistor in the circuit, when there's already an amplifier chip involved, absolutely terrible design, and that's definitely not how staging works, he didn't bias a single thing, all I heard was distortion, and that means you failed to actually build the amplifier, I am laughing louder than the distorted noise you claim is an amplifier right now, ....no.

[@TheMasterChill]

LM358 or LM4562? Which is better

[@ronniepirtlejr2606]

Why dont you use a circuit board or a breadboard? That looks ridiculous!

[@anthony4312]

He has bread, but no breadboard.

[@ronniepirtlejr2606]

@@anthony4312 they are dirt cheap on ebay!

[@rajadas5941]

Can i use 13001 transistor

[@TruongNguyen-uk5nd]

Không có d882 thay bằng d718 được không ạ

[@alisonleal9668]

how to make without direct dc on speaker?

[@htim2490]

Why you want to make noise to show us ?

[@inventionmaniabyzahed9458]

Ise voltage supply kitne volt ka diya hai

[@sinanzeee1842]

What is the input voltage

[@darkavenger5155]

Does it really work

[@ajaysantra5474]

Super

[@friskyboys413]

which one software did you edit this video plz tell me

[@sanjeevkohli6270]

Sir only lm358 se nhi bana sakte kya esme d882 transistor lagana jaruri hai kya aagar jaruri hai to ham shirf transistor se hi bana lege lekin usme low volume ki problem aati hai sir me chahta hu ki aap shirf lm358 se bana kar dikhaiye

[@kristofkulczycki2169]

Hi...the transistor is pnp or npn...can i use another transistor

[@zcreativetech1509]

Npn

[@meeskees4227]

I think npn

[@ritaisabel8665]

Good

[@debmalyamitra353]

Schematic do.

[@timmyh52188]

Why you make noise?

[@ronniepirtlejr2606]

Lots of distortion.

[@vikrantshanbhag]

Because the speaker is directly connected to the supply. So there is both DC as well as AC passing through the speaker. It's the worst way to drive a speaker.

[@manofmesopotamia7602]

the sound is noisy, because the battery is not railed

[@simonndungu1196]

Thanks

[@kingbacod1652]

Many watt

[@vishalkanwar1524]

stooooooooooooop music and explain

[@RepairsMX]

Chida tu herramienta de sujetar el ic, habías de compartirnos la, ecxelente idea este video. Gracias

[@jamatif2168]

W .b NB

[@francoisdastardly4405]

All in this video is WRONG ! OMG ! This is a death sentence for the speaker ! N

[@robinjandrews7680]

Bro its working

[@dfn03]

That circuit is oscillating very badly.

[@sharatchandr6945]

Bad output from speaker.

[@nishantvikaschandgude7148]

We can use 9volt supply Please reply fast

[@CreativeGoutam]

Yes.

[@nishantvikaschandgude7148]

Thanks

[@hameedsaeed9520]

Very bad
