"fairly fundamental to generate a frequency" ... Was that deliberate? Puns like that one really resonate with me.
😂 I see what you did there. Resonates with me as well
you may generate harmonic to each other be careful
Damn, he's good.
Sounds good
@@nagasaipurvaz4251what does harmonic to each other mean?
Thanks!
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.
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!
I'm in the same situation. Where did he go? Hope he's alright.
@@alexbarnett8541 we'd definitely love to have him be active on the platform.
Why did it take 2years for my algo to find this channel? It has everything im looking for everyday..
It’s not an everyday kind of channel, but it’s here wen you need it :)
@Mihály Tóth Depends on the op-amps, most can handle up to 500 kHz or so.
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.
did the 741 opamps come from ebay or another cheap source? lots of them are fakes.
You're projects are just EPIC!!! Love your content sooo much!!!!
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.
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!
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
Bro you saved my life I love you
Happy to be of assistance
@@BlueprintScience I just wonder, why didn't you use the second potentiometer on the PCB
Thanks very much for this. You make it look so easy!!!
I hope he will start uploading again soon!
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
I think this is one of the only videos that is actually educational the rest is just nosense about spiritually and other related things.
Nice. I always like this type of videos
Thank You Dayton Aardema / Blueprint For Your Video, Keep Up The Good Work and Thumbs up! 👍
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.
Haven't posted for a while now, hope all is well.
Not to worry
@@BlueprintScienceare you going to upload again on YT Hope all is well
4:42 I think that it's a non inverting amplifier, as the input is given to pin 3 of the 741 Op Amp
This was amazing thank you
COME BACK!!!!!......i love you....
Okay
@@BlueprintScience Good. I'm sorry I had to lay down the hammer like that in front of the kids, but I'm glad they saw it.
😅with?@@StoicMaverick
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.
What can be done to adjust the duty cycle of the square wave?
great, can i apply this to an inverter cckt to design a sine wave inverter
Very good explanation and useful video, thanks for sharing
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.
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.
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?
You'd need to amplify the signal to be able to hear it through a speaker.
@@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
Sir which book would you suggest for beginner to advanced level material
How many frequency/duty cycle are produce maximum and how to change it
you know i bought a little kit build one of these and when reading the comments after it arrived, I realized i could of made this very circuit you build here, and it would have done the same functions the 7 euro one from bang-good can do.
plus i have all the parts i need to build it it...
I might go ahead and put the 555 one together & see which generator works better, I'll put th it in case 555 one in the case that came with the kit if it works better(which i can tell it already can) i think i''ll call it ("DAYTON" VERSION 2)..
now to watch the video "AGAIN".
God bless you, do you think you could create a bipolar square wave generator, thanks.
I prefer the electronic engineered items. They are very interesting.
Can I still get Gerbers etc.?
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.
@@BlueprintSciencewhy you don't make videos
Can i use small signal diodes for all the diodes in the circuit since i have loads of those?
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.
DAYTON, i have a question? You know the ya can make these with a 555(and filtering on the output) a half wave rectified sine wave a transistor & more low pass filtering like the 555.. But iv never seen this form before, would this version be better in an effects peddle for an electric guitar?? i was thinking maybe yes because of the op-amps been used in this design!! am i right or would it not really matter coz my next project is making some effects peddles and amplifiers for my guitars. would you recommend this wave gen made from op-amps for what im planning?? anyone who can answer this for me i would grateful?? I'LL TAKE ANY INPUT THAT'S OFFERED : )
OH 7 DAYTON IV TAKING A SCREEN PIC OF THE SCHEMATIC & HAVE IT SAVE INTO MY SCHEMATIC FOLDER.. : )
THANKS FOR SHOWING ME SOME NEW, MY MOTTO IS ANY DAY YOU LEARN SOMETHING NEW!! THAT DAY WASN'T A WASTE OF TIME!!
P.S. SORRY FOR BABBLING ON FOR SO LONG IN MY MESSAGE BUT IT WAS MY UNCLES FUNERAL TODAY(WHO WAS ALSO MY BEST FRIEND) AND YOUR VIDEO CHEERED ME UP FOR THE 1ST TIME ALL DAY!! & MADE MADE MY TAKE MY MIND OFF HIM. (SO THANKS FOR THAT BIGTIME)
Thank you for this video. How low can the frequency get?
Can you make a circuit design which can make 1 KH to 5GH?
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.
Glad you liked it!
And no, I have not. I try to keep these tutorial circuits using common parts for ppl to replicate and build upon.
@@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 ruclips.net/video/XFEQK2ERZpM/видео.html
The cheapest popular 1N4148 switching diodes will be much faster, cheaper and smaller than the rectifier diodes used here.
Ca-n You Make a muzical tesla coil circuit and explain how IT works pls?
It's been on my list for a long time - its a long list...
I need to build a 10.7 mHz and a 98 mHz sine wave, can I use this circuit?
How many Farads do I need for the output capacitor at the sine wave?
So I suppose a modern TiG welding machine must use circuits similar to this only with much higher current rating to do AC welding of aluminum alloys and such. Interesting thanks for the video.
We need you back!!!
Nice! Wondering why you didn’t use bypass caps in the power supply as well as for each IC..?
Hello
I would like to build a frequency generator that somehow would produce physical vibrations for healing the human body. The human DNA frequency is 528 Hz. Would this board somehow work and could you enlighten me I what id need to do plz?
Try to eat only meat for 3 months... You will not have nothing more to have to heal
Great content i love your channel for that same reason
More, I want more🙌👏
Congratulations !!!!
Nice you voice ,I'm Indian
Cool video, well done, like it, thanks for sharing it with us :)
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.
QUESTION: how to transform this frequencies into sound/ tone?
The output is already audio (20hz to 20000hz). You would just need to plug it into a speaker in order to hear it.
@@BlueprintScience oh wauuu. The second board u showed, where can i get it with al the components?
We can use as signal jammer ?
My output for sine wave is not correct, the upper peak of sine wave is cutting... What can I do for it?
Why aren’t you uploading any videos? We rally love youre contents
I’m not gone forever. But it was important that I step away for a while
@@BlueprintScience Why man why?
great video man!
And what can this sine wave use for I don’t know is this can use for driving mosfets
what kind of connection or setup you used to see waves output on display screen?
That was a digital oscilloscope
how can I change the vp-p of each of the signal
Simulated in Proteus, it does not go over 8kHz and at such frequency it is highly distorted
where can I buy one ??
Does this also operate in 12 Volt
I tried to build this circuit and it only operates with batteries and not with a split power supply circuit, why? :(
Split power supply should be fine *if* it is isolated output - make sure that they don't share a common ground.
What is the frequency range of this circuit?
is it possible to make so that i outputs 20 volts?
How can I add 1 or 2 amps on the output?
use a MOSFET transistor to boost it up
Very well., Thanks
How to design frequency generator, in which which different frequency sounds can be generated and controlled with speakers! Like 432, 512 hz sounds!
Shed some light!
Its really nice... Could you please help me to design microcontroller based ultrasonic frequency generator.
If the freq only 50 Hz, does it works?
how do i create 222,222 herz in my house? thanks!
Man I thought you were dead because you don't upload videos anymore :(
Yeah it’s a bummer he doesn’t upload anymore. His content is really good.
Love your video
is the power source ac or dc voltage?
Nice project. Can you please make a ZVS driver?
How can i get that board which is easy to build the function generator ?
Thanks
On the schematic the R8 needs a wire connection to ground ?
Um... yeah. Looks like I forgot to draw that wire in - oops
@@BlueprintScience too late , burned down my house
What componentry do I need
I want to build a 528 hz sound generator that's like a nightlight with a clear Crystal and may be a 528 mini tuning fork also. Have a lot of ideas but to keep it simple stupid I'm not good at.
Any update
can i generate 16ghz signal by using this?
No. You won't even get close.
There are very expensive solid state microwave circuits like the ones used in 5G. Otherwise, your most inexpensive option is a 16GHz magnetron tube.
capacitor between output and ground, isnt the wobble parasitic capacitance?
If that took you 15 minutes you are MUCH more skilled at soldering than I am... It would have taken me an hour an I would have burned at least one hole in something.
You can control frequency with potentiometer but what about amplitude?
Thanks for sharing
Can this be modified to cover the audio frequencies?
Someone please give me a list, How many of each component is used here? with there value. please ,,please ,,please
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.
This is a sine inverter, but it won’t do 120V or 240V. A “pure” sine inverter at those voltages modulates a PWM, that can be complicated.
@@BlueprintScience Thank you very much..
Can we hear the frequency??
master to output signal how many volts.
can u do one with only non-integrated components?
How can I build one for 20 amps?
Square waves, triangle waves, sine waves... When are we gonna create a hyperbolic wave?
Can I replace the zener diodes with normal ones
No.
Zener diodes are special because they only conduct one-way if the voltage is over 5V - unlike normal diodes.
Ive got 2 Varriable frequency relaxation oscillators on my person right now.
Can you build one with 1.5 volt AC input , with 120volt AC output ?
Probably not.
@@BlueprintScience Be cool if you could , but thanks a lot for answering back .
