"fairly fundamental to generate a frequency" ... Was that deliberate? Puns like that one really resonate with me.

I added an extra amp, free for any output, next I’m designing an “addition” to it, to step up and down the outputs. After that I’ll clone the signals. Leaving them to be tampered with at any point. Thanks for your explanations, time and background music. The music really adds to your output. Love you.
God Bless.

Thanks for Posting. I have built your circuit and have used the uA741 op amps. But in doing so I found that the square wave and sine wave were extremely distorted. I inserted a CA3140 high performance op-amp. And the square wave was greatly improved. Cheers.

DUDE!! Make more videos where have you gone I just found your channel today and I absolutely love it you’re very informative and hilarious it’s great!

You're projects are just EPIC!!! Love your content sooo much!!!!

[AtlasReburdened]

Nice. I remember making my first op amp function gen. I only had a quad op amp at the time so I used the last one to just output a sine that was 180° out of phase with the first.

[hhhh]

I have subscribed to this useful channel and I will give you admiration for my conviction because it is educational. I hope that you will provide us with an explanation of how the two frequencies 3KHz & 15KHz are compared and how they are treated. Thank you

Neat little circuit and demonstration of performance very sane. I'm starting to look at the winter indoor projects again where one category relates to the welders (HV &/or HC) where I'm wanting to upgrade the older transformer systems to have more modern features and also see how to improve the ones I can afford that are the IGBT in my situation (looks like some are MOSFET designs). So one of the easiest improvements, outside of CV/CC controls and/or improvements, seems to be switching controls basically to control better in the sine and pulse ways. Though you got me thinking about the sawtooth and triangle ways now with a nice simple circuit also without the MCU's. Thanks for the inspiration and details. Maybe the same design and detail with sawtooth and even better sawtooth in the two directions will be a great supplement video. Thanks again!

I love this channel. Tanks for this video I want to be like you.

Dayton.. I saw the recent mini lev project and it brought back memories of attempting Eric laithright (I believe) demonstration of having a solenoid within another, both receiving ac but in opposite direction(clockwise-counter etc..), to attempt stable lev w/o a sensor.. I’d love to see it done right by a pro

[philosyche]

Hey, love the channel! I'm new to electronics and I was wondering whether this circuit can be used for making audio by hooking up the outputs into an audio interface?

[yura]

I hope he will start uploading again soon!

[BarryMcGowan]

Thanks very much for this. You make it look so easy!!!

[truthseeker]

Thank You Dayton Aardema / Blueprint For Your Video, Keep Up The Good Work and Thumbs up! 👍

[skyzra]

Why did it take 2years for my algo to find this channel? It has everything im looking for everyday..

[terencekaye]

Great vid nice to see you posting. Just wondering what the full frequency range would be lowest to highest( 100k) i think you mentioned also what amplitude range? thanks for the files and the schematic.

[tze-ven]

At 5:11, your Q2 PNP transistor is incorrectly connected in reverse. Although it appears to function in the reversed connection you made in the schematic (because BJTs can operate in the reverse-active mode), there will be no amplification, and you wouldn’t want that.

[TerryD]

Why did you design the pcb layout with the connectiing tracks on the top of the board instead of the more traditional underside as it is essentially a single sided board? It would make etching a board at home much simpler if it was, and make it a more 'budget' project.

[Blazing_DP]

how can i implement his in an inverter? someone pls help, I think I'm about to lose my job over this delay. I need guidiance, I'm already tiring out on the building of this inverter, meant for a product pls.
I'm an intern with a heavy work on me, for your info pls.

[yorkiedanMC]

I think this is one of the only videos that is actually educational the rest is just nosense about spiritually and other related things.
