Study Break Episode 2: Audio Amplifiers

[vze4p6c2]

lol, that cap is blown!!!!

[jarheadwithm16]

Where is the audio input?

[neveragaineverever]

SO NERDY!!! perfect example of assburgers

[theemusic92]

What's the point of the Bypass? Plz. Anyone?

[ZoNaDTVideos]

the 1.00 cap is broken...

[Augray37]

Boiler UP!

[ciprianwiner]

i can't wait to get my LM386, and you should try TDA2003 and TDA2006 they have enough power :D

[D1LENGER]

now wait a minute, i think i better talk to my mother about this...

[ventureelect]

That cap is defective. Tis bulging lol.

[138NProgress]

hahhahha the dancing at the end had me cracking up

[juanfelipejuan72]

I need help, im just a beginner just send me a PM.

[kingswayguitar]

how did you manage to solder the stereo ic directly to the board? i always use sockets but maybe i don't need to, eh?

[stuDIYbreak]

@kingswayguitar the sockets aren't necessary (helpful, though)

[SaxoAcapella]

If you put a 10mfd electrolytic capacitor between pin 1 and eight, you gonna increase its gain to 200 (46 db) and that's loud enough for a small room setup for a fairly good speaker.

[qAyyUm]

what does audio Amplifier does? make the speaker more loud or what?>

[pegasomarcelo]

SEE MY AMP:

[LauxHawk]

I love your videos.

[BlanchProductions]

"pop a cap" oh thats a knee slapper

[mragw]

thx guys!!!

[cumesoftware]

Thanks for another interesting video! A remark: 2 x 2W is very good considering that the TDA7268 is just a chip amplifier.

[michael10725]

Thanks. funny. oh and did i say/type THANKS!!! Nope don't think I DiD Peace!!!

[VictoriaFalls12]

Great vid guys, thanks a lot .. I'm gonna have me a go!

[aeronut01]

The lm386 is a half watt only!? then why am i able to power a 2watt speaker and make it go really loud without damaging the chip?

[CoolDudeClem]

The lm386 comes in many "varieties" 0.3, 0.5 and 0.7 watt and I think there's is also a 30 watt version of the lm386. Your one might be one of the more powerful ones, besides even half a watt can sound quite loud if you use good speakers.

[cumesoftware]

Actually it is the other way around. You won't damage the speaker since it rated to a superior wattage than the signal output from the amplifier.

[Mushketer888]

thanks!

[imwatching22]

chip amplifiers? thats weak man......

[lucasmatt1]

Thanks Ben and George for this excellente video and lesson about audio amplifiers...

I wish that their lesson about audio amplifiers had forgotten,because it is very exceptional...

[Eskobar20008]

your schematics and your bread board set up is not the same!

[stuDIYbreak]

The circuit that was breadboarded is the first schematic presented with the exception that the potentiometer was simply replaced with a fixed voltage (Vdd). But yes, there is a small discrepancy.

[Eskobar20008]

thanx

[AMDkicksass]

lol 00:56 i think you cooked that cap

[OnnomonnomonnO]

yeah..that cap is fucked :D

[tuifijitime]

good video that was funny

[coondogtheman1234]

i feel like making one of these and posting a video of me making it but mostly i just hack into electronics to harvest and use the amps, i can hijack the volume control of an amp and connect a line in into it

[Amishman35]

At 1:00 it looks like some anarchist smoked your capacitor by reverse biasing it.

[popopo1275]

next time show be more discriptiv or show it more

[uberscientist]

nice! great idea, keep the videos coming

[Berkner80]

Like you videos. I am just starting in electronics. I have read a lot but would like to build a project. Would this be a good starter project. I have also looked at the 555 timer projects.

[lickthebubble]

freeken geek

[svetdude]

shut up you asshole

[etharooni]

Awesome, I think I might make one. I think you should include a PDF or schematic in the description, along with your email addresses: I don't think most people would take the time to copy your email from the video.

[mysterymeatgrinder]

2 watts? That thing is just a toy! :D Good beginner project though. I've been there too!

The amp I'm working on right now is a 400W digitally controlled beast.

[Amishman35]

I added an LM386 amplifier to my "beater" Gameboy Advance and made the sound come out of the original speaker, with a 9 volt snap and most of the circuit hot-melt glued to the outside of the GBA. Now I can play most of my music collection in vibrant mono on my GBA through the tiny GBA speaker. It still hasn't blown the speaker yet, even when I played songs that I used Audacity's Leveler on Heavier AND I used clipping on the GBA music player. Of course, if you do use clipping, your ears bleed.

[rlamoth3]

nice video guys.. keep them coming..
