Electronics Basics & A Simple Oscillator!

Support the channel! :)
/ theaudiophool
Today we're going to go over the basics of voltages & currents along with a resistor, a capacitor and a funky op-amp to make ourselves a super simple CMOS oscillator!
Thanks! :)

[@bankhead9285]

count me in to along for the ride. thank you for this awesome information, and opportunity to learn.

[@TheAudioPhool]

Welcome along! You're very welcome :)

[@brianhagen8244]

This is the most clear and thorough explanation of the IC that I have yet to see! Well done!

[@jvk86]

Damn, I am an absolute beginner just learning the basics of electronics for the first time and I thought this all would go way over my head but yet I feel like you explained it all so clearly that I actually understood what you were talking about! Well done, sir!

[@mycbeats1276]

This is fantastic!

[@kmrokmro7981]

I build this oscillator today and it worked great! Thanks for the combo of lecture and demo on the breadboard. Great way to better understand.

[@TheAudioPhool]

Glad to hear it! Thanks for watching :)

[@zlapidus]

Excellent, thank you! Please keep it up - your explanations just click very well.

[@bubuAudio]

instant subscription !!! 😍 I wish I discovered this before

[@AndrewPineiderMusic]

Great content man!!! Really loving this stuff

[@ChrisGozzardThatPhysicsGuy]

Fantastic series!❤

[@The2011andrey]

wow! congrats on starting this tutorial series

[@cybermortal1983]

great video thank. just getting into DIY and learned a lot here.

[@ElectronicElevation]

This is a brilliant lecture!

[@davidpape1160]

I flipping love videos that really show how bits of circuits work. Superb, thanks!

[@mikeoliver3254]

Easy to follow instruction, good job subscribed looking forward to what else you do. I’m actually trying to build my first real(ish) synth so I can’t wait to see what comes later.

[@kenjayfx]

Thank you so much for this video. Clear and concise with explanation on how it works which can be lacking from other videos. Can’t wait to learn more by following your content.

[@TheNaboen]

brilliant! so glad I found this channel. a real treasure chest

[@TheAudioPhool]

Glad to have you! :)

[@alfredo3980]

amazing content ✔︎

[@mardav1545]

The differences in the thresholds is called hysteresis. I don't think that the cd40106 hex inverting amplifier has hysteresis built in. You really do a good job of explaining how things work and it's appreciated greatly. Thanks

[@redlab3488]

Very detailed and instructive. Thanks for sharing your knowledge. I guess you already realized that the whiteboard is not always readable. So with an upgrade on that part this would be perfect.

[@tingstrap]

I'm in! Subbed

[@chrissold5957]

Perhaps it would be good to mention that there is very low current going into the inputs - but at all a super explanation to begin with

[@smileypoopsniffer]

Awesome video, thanks for the easy explanations. I have a few questions though. Is it possible with the other five inverters plugged into the output in their own closed circuits to make more than one oscillator? Also, what exactly did you use to plug in to your audio out? Thanks in advance.

[@TheAudioPhool]

Absolutely! you can hook up all 5 of the other inverters the exact same way. If you watch this video there's an example of how to use another oscillator so make a bit more of a complex sound out of the 40106. kzbin.info/www/bejne/o2mbaJedqdOFZpY I think i'm gonna do a quick video on that cause i've had a few questions about the speaker setup. I have just a pair of computer speakers with a 3.5mm stereo jack (just the normal one that plugs into your pc) i have some crocodile clips with breadboard jumpers attached to them. One clip attached to the ring of the jack and one to the tip. the ring is connected to the circuit ground and the tip is connected to the output signal :) www.majorcom.fr/files/pmedia/public/r413_9_image_trs_vers_rca-2.png This will show you what's the ring and whats the tip if you're not sure. Thanks for watching!!

You make something seemingly difficult easy to understand.

[@jeffsprings928]

I always wondered how the comparator inside a 555 worked

[@Paes64]

Schmitt trigger is not the same as operational amplifier. Schmitt trigger may be made of opamp but not reversely.

[@treeski3410]

I just built the circuit from your instructions and it works great. I have the same oscilloscope and was able to see the two concurrent signals overlap which was pretty amazing. I also tried different capacitors to see the effect on the frequency range. It's really helped me understand this basic circuit design and function, so thanks! I would like to go deeper and learn how the Schmitt trigger works and transistor circuit behavior in general so will be viewing your other videos. Did you ever do a speaker set up video? I ask because I'm also following Mortiz Klein's DIY VCO video and he mentioned needing a buffer so as to not affect the oscillator current when connecting speakers. Does the "circuitry" you mention in typical external computer speakers act as a buffer?

[@treeski3410]

Did you ever do a speaker set up video?

[@TheAudioPhool]

Hey mate! Only just seen these. Don't always see comments on older videos so sorry about that! Yes that's basically what i'm referring to!! Just any old set of cheapo desktop computer speakers will do just fine. Occasioanlly you have to give it a helping hand with a resistor divider. I haven't done it on the channel but i'm doing a Patron questions video soon so i'll make sure to give this a mention in there :)

[@ChristianKrupa]

Looking at the rise and fall of the capacitor voltage, I can’t help but wonder if it’s possible to tap that lovely saw wave :)

[@TheAudioPhool]

It is! You just need a buffer.

[@ChristianKrupa]

@@TheAudioPhool that was my suspicion, I may try this tomorrow; I’ve been building a workshop that I’m finally able to spend the time in for a few weeks as part of an arts council project using valves as sound generators…

[@kevinlemming6268]

Tried this and just got a quiet high pitched whistle.... Duff ic?

[@TheSpazzattack95]

Wer can i hit u up??

[@pixelklaine357]

Hello, i really enjoy your videos & channel. Recently i started interest in analog synthesizer and that's why i have some questions for u: I have an midi controll keyboard (which based on scan matrix technology with arduino) How i can propely send midi signal to oscillator, and after it my oscillator should play correct note? Mb i need second arduino, but how i can achive, this ? If u know how, please share some links Thanks, for answer, i really appreciate it :3

[@TheSpazzattack95]

I need u bro..

[@twobob]

Good explanation. Blow your nose!

[@1495978707]

Fantastic idea for a series, please keep at it man! A note I’ll give is that I have the impression that you didn’t use a script. In particular, you often jump between the levels of background experience people have, which is a bit jarring. Pick an audience and write a script for that audience.

[@alexmoore7667]

I disagree with Liam. AudioPhool has obviously taught people before and knows his stuff. He's trying to teach, not become a KZbin celebrity. Put some effort in understanding and you won't feel "jarred"
