The Paia VCF design is very interesting. As to minimize the load of the following simple transistor amplifier, you changed it into a more complex bootstrapping-stage ... but would it not be simpler to add an emitter follower between the filter part and the amplifier part?

Hi - great videos. Could you please share your email? I wanted to discuss a commission with you. Thanks.

Shouldn't the capacitor and the resistor in series to get a decay output? The voltage will be a constant 9V in your diagram I suppose

This is fantastic. Well explained. Thank you

0:29 haha fundamental pun

Brilliant! explanation.. superb!

I always wondered how the comparator inside a 555 worked

Heeeeeyyyyy op amps just clicked

you wanna tell us how you powered the opamp???

@electroboomb

This is your last video, is that permanent?

You deserve millions of subs, for such good beginner videos! :) I am a retired electronics engineer and I always struggled to explain in simple terms to juniors, and you do it GREAT!!!!!!!!!!!!!!!!! :)

i remember i saw some of soundcraft console schematics. and found out interesting summing circuit. so pity i forgot what model it was...

Good video. Here is a Wien oscillator using a light bulb instead of a fet. It's based on an HP signal generator. kzbin.info/www/bejne/iKCkiXt-nc94ea8 I have 2 other examples on my channel.

I wonder how low a frequency this circuit can create. Looking for 7.83 hz. the heartbeat of earth itself.

Thank you!

would it be simple enough to do this with a usb-c connection instead of a wall wart?

1 subscribe, 1 like for your effort sir, thank you for making this amazing content

All that is missing is the follow up video of this project.

Where are you? We miss you? :(

what voltages does a 7915 put out?

holy shit what an action-packed and well done video. this connected a lot of ancient college memories to what I'm working on now. thanks!

I know this is an older video but i just want to say thank you so much for your in depth explanation and example schematics. This video was the inspiration for my senior design project where me and a partner built a really cool modular synth style guitar pedal with a 3-notch phaser and all of the notches broken out with 3.5mm jacks. We also made a whole stage of digital effects using a Daisy Seed and because of your channel, my partner and I graduated last weekend with BS's in electrical engineering at the university of florida. Much love!!!

Optocouplers with cellotape. You funny

Actually, no electronic device is 100% perfect, it is currently not humanly possible to make electronic components that are 100% perfect, even a simple copper wire isn't 100% perfect.

very good practical tutorial. thanks

Are you ok? You haven’t made a video in a very long time.

Wow, what a truly educational video. Learnt so much that others just dont teach. Perhaps we should rename you "Carlsberg". If Carlsberg did Electronics videos.......

Hi, thanks for sharing the wonderful knowledge.. At 8:15, you assumed the output to be zero volt. Could you please help me understating this assumption. Could you please share some reference for that. Thanks

Come on now, back on the horse please! I'm actually learning stuff here! 😁

Great video thanks: I have a 220/24vAC transf which I'd like to use for +/-15vdc- can we take same design and just modify resistors/capacitor values?

Wytse, its 2999,- and on Thomann. Why the Carbon? Aluminium would have been fine. Is it really as good as Emperical labs or SSL?

I really like this video and how much you know about electrical engineering and small signal design. But I also love that the dude teaching me about EE also has a lapel mic with a missing ground lololol. If you had no noise gate, I would die.

Such great presentation of this concept! Subscribed.

Such a good video, learned a heap.

What if you not only put the amplitude of the waves out of phase of each other, but also had the frequencies of the waves not match so they overlap at less predictable moments? What would that sound like? What would you call this effect?

aw shwucks he ded

Your explanation is a great one

You deserve more Subs!

these really are some of the best little circuits AND explanations online. thanks.

Man I love these detailed explanations Can you please link the wave shaping part you mentioned in the end?

I would describe an diode in forward bias as a 0.7 V voltage source, not a short. A short means that both terminals have the same voltage. What's important is that current is not limited (like in an voltage source).

… and by driving that capacitor feedback opamp with pulses you get a stairstep.

yeah manim animation.

Reminds me of those auditory tests

Thanks for posting. If + input of opamp starts at 1 at peak of osc and - input starts at 0, then diff is 1 so it outputs 1 and then the diff is 0, so…..how does that function if diff is 0 at that point? Basically it seems as though it would outputting a binary toggle as voltage is + on + input.

I've had trouble understanding how op amps work but you've helped clarify several points. Thank you for the great explanation

Nice tutorial. How to choose quality low noise components?
