Thanks for your explanations, time and background music. The music really adds to your output. Love you. God Bless.
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.
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.
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.
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!
Of course. In the video description is a link to download a zip folder called “CAM Outputs” - when an online PCB fab (I.e. JLC PCB, or Oshpark) asks for gerbers, just drag and drop the whole zip folder there and it will configure automatically.
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.
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
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.
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
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?
@@Scyth3934 Could I incorporate an op-amp like the tl074, and use the output for recording audio? Would I be able to use multiple circuits like this and run them through a single op-amp and have them come through the single output?
@philosyche I'm not that good with electronics either and I haven't even watched the whole video yet haha- your guess is as good as mine for that one
I have tried making a frequency generator from a 555 timer with low pass chain, but they all sound the same like square waves but lower in volume. Can't figure out why I'm not getting triangle and sine.
Thanks for the video. This diode method has a much wider bandwidth and flatter frequency response than a traditional RC sine filter. Just what I've been looking for. Have you tried using switching diodes instead of 4007 ? Just curious.
@@BlueprintScience I will try substituting the XR2206 function generator in my transmitter project with your diode circuit. Not sure if the op amps I have on hand are fast enough for a flat 1 MHz BW triangle (500kMhz to 1.5MHz). The XR2206 is much flatter than a typical tank circuit VFO, but there is still significant attenuation at the higher end of the band past 900k. See th-cam.com/video/XFEQK2ERZpM/w-d-xo.html
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.

master, please tell me the shecematic circuit, can it be used in the car ECM simulator to replace the CKP signal generator trigger. Inductive type CMP and Haal effect thank you
Well… If you use the circuit shown in this video, the V-tri in the schematic could fake an inductive signal since it oscillates around several hundred hertz. And you will, of course, need to adjust the amplitude depending on whether you are simulating an idling signal or engine-cranking signal. However, the regular electrical dropouts might not agree with the ECM… Additionally, you could inject an audio signal using your computer/phone Aux output (like for headphones). You computer should have no issue replicating the signal if you use an online tone generator. Hall effect gear-tooth counters are a little trickier since they are digital signals. I would suggest using an inexpensive Arduino microcontroller and use the digitalWrite HIGH and LOW function with a delay to replicate the digital pattern.
i know you will probably never read this but i need help- our project is to determine on which factors the self inductance of a coil depends by observing the effect of this coil when put in series with a resistor/bulb in a circuit fed up by an AC source of adjustable frequency., how should i make the circuit for the model. iam in high school btw
Not sure that I understand the question. It sounds like you’re trying to make an RL (resistive-inductive) circuit. You could try an internet search for “first order circuits” - that should get you started.
Is this for sound, electrical, vibration or something else? How can I create a device that generates 100,000 hz - 300,000 hz? Please forgive my ignorance.
hello sir, i am new hobbiest i want to ask if this project could be interfaced to a simple inverter so that i could attain a pure sine wave output? i appreciate very much for your recommendations ang good help.
That’s not going to happen on a board like this. Your best bet may be to generate a frequency then use a PLL (phase locked loop) to multiply it to a higher frequency. But you’re rapidly departing electronics theory and entering into antenna theory territory at this frequency- same rules do not apply.
Thanks!
"fairly fundamental to generate a frequency" ... Was that deliberate? Puns like that one really resonate with me.
