[@polkaputo3226]

i love how straightforward this is, i’m sure i could replicate it very easily. but i have no idea wtf is happening lmao

[@Morbrek]

Any chance of a discussion of why the wires go where they do? Or maybe a list of what each one does in the process? Would love to build one. And with these instructions I can. But I would like to know why it works.

[@tapansaini8577]

What is the frequency range we get from this circuit ? Pl. Tell.

[@Inquire98]

"Thank GOD", and thank you very much for your support and time 😉 REALLY good simple video 😉

[@KeystoneScience]

If you have trouble changing the tune, try putting the 500k pot. In parallel with the 20k pot.

[@moiz6145]

instead of making a tone generator ca a use a boom box to produce diff amplitudes

[@seanogrady2629]

Nice video. I am new at this, but is there such a thing as digital indicator for the potentiameters to be sure you are at the right frequency?

[@andyleerogers]

could this generate a frequency of 17khz and above?

[@godsinfantry8746]

Where can a beginner find these supplies?

[@tomjeffersonwasright2288]

Very clear explanation, and no wasted time. Thanks ! ! !

[@Pedro8k]

I made one of these in a empty marker pen as a audio tone injection probe useful for testing mic pre amps stages just adjust the level in and listen on the output

[@ScreenPrintR]

Could you connect that tone to a transmitter, and use a locator/receiver to find the tone? Like putting the Tone Generator underground and using the receiver above ground to find it?

[@johnd942]

Do you think you could speak a bit FASTER!!!? I guess the end of the world must be upon us...

[@lalanirhythmchanter5566]

Can you tell me what range Frequencies? Also i meed help figurong how to connect plants w biofeedback deal and i know synthesizer is involved..want to hear plants sing 🎶 thank you, perhaps i could email you then speak via phone at some point? In Missouri

[@eleoos]

Very good video. Congrats. You ve earned my thumbs up and subscription. Could I suggest a tdr (time domain reflectometer) maybe based on arduino for your next project? I tries to find on the internet but nothing. Think about it.

[@Phant_m]

this didnt work for me. my power supply's jumper cables just started smoking

[@wanfirdaus7760]

Hey sir, im from malaysia and i have some trouble in my final projects. I just want to know how to combined the buzzer circuit to audio circuit (amplifier circuit). Please help me to solved that problem.

[@KeystoneScience]

for this circuit? it would just be one end of the buzzer to pin 3, and the other to ground.

[@Felipe-gy8gf]

what is the hertz range it emits?

[@marioronci5338]

Can i do this with only one potientometer why do you need 2?, i got one in my kit but no more is this circuit still possible with 1 poteintmeter

[@bugsbunny8691]

Dude! Where has this channel been all my life. I'll come here often.

[@Magsiplays]

can you lease send me the cleared circuit of this project in a bread board plz

[@PotionsMaster666]

That's all good but how does it works ?

[@pain5140]

Hello !!! i have a problem...i can't set it for higher freqvencies it going from 0.10 hz to abaut 200 hz... what is the problem in my conecctions...? If i skip the potentiometer ..just its sounds maxx about 200hz ... tank u.. sorrry for my bad enghlish

[@jamesbarrett5283]

I need to make six of these that can create different frequencies ranging from 180hz to 630hz, and operate them all at once. can you help me with values. I own an oscilloscope and know how to use it for fine tuning.

[@MD62383]

Do you know how to do the same with Piezo technology

[@MichaelStephenLau]

Please explain what each component does in the circuit. That would be very helpful.

[@satishs2278]

Bro can i generate sound frequency of 25k hz by the help of this circuit

[@alexeyegorov2036]

Already you can, I just changed the 4,7 capacitor to a 0.01 capacitor and I generated a lower Frecuency.

[@jimmeiroawuchi6785]

Thanks, nice video. but i want to see how to make a tone generator in the giga hertz range.

[@KeystoneScience]

+Jimme Iroawuchi umm you need basically to use an inductance capacitance resonator, and a transistor that is able to handle switching so fast. Why do you want this? For wifi?

[@stonecold7945]

Keystone Science what is inductance capacitance

[@henryswan1374]

i would also like to see a video on that, for a tesla coil driver

[@keatonspence9306]

Is there a way to make a sweeping tone generator example a tone that makes a sweep from 0 to 530 Hertz in 6 seconds

[@ka-waiimoon4288]

Is there any way to produce sounds in the kilohertz range, like around 20-30 as a vicious dog repellent?

[@lonewolfe3100]

What device is used to muffle or greatly reduce very loud noise???

[@deadlinkofficialartst5592]

I would use this with my moog synth

[@darrelseely4817]

Can you apply that for under water applications in the 100 to 500hz range? (Asking for a friend lol)

[@ifell3]

Ok, i was thinking, can you use this to set a transistor to change frequency of ac or dc, high voltage or high amperage? Great set out of video, clear and easy to understand without BS!!!

[@enegberon6478]

what is the board called?

[@Hammerjockeyrepair]

I followed this exactly, and I get a tone thats adjustable but its only working from like 1hz to 60hz

[@richardchear9850]

Hi I'm new to circuits so if anyone can explain a few questions that would be great! One is how do I connect the mosfet to pin 5 if I'm using a breadboard? Why are the numbers for the pins switched(sorry i'm new to circuits). And do I really need an amplifier to connect to the speakers, or can i just hook up the solar panel to the speaker and that should be fine?

[@mateenahmed6123]

Listen I am a complete newbie around those thing. All I want to ask I how will I possibly increase the frequency

[@godsinfantry8746]

Rife frequency healing

[@lucakonecsny7712]

Wouldn't be one Potentiometer enough, just the frequency range would be limited?

[@1GLO919]

+Keystone Science I have the TLC555CP but it doesn't work can you help me please?

[@Mindcroscope]

有難う御座います。 🎌👀👍

[@georgegates526]

Hi Mr. Keystone Science. Is it correct to say that the 2 potentiometers are being used as fine and coarse resistors?

[@da_SpiffR]

A very handy device! Thanks, and great video.

[@23antwon23]

Thank you for the awesome video 🤌🏻 Can this circuit be used as a PWM signal?

[@deadlinkofficialartst5592]

Nice sawtooth waves

[@stevenaustin4591]

plz do a video on how to hook up a FM sound chip to a MIDI controller!

[@carlcreary875]

Make a dub siren

[@chemosis8259]

i was wondering if this could be also used as a lfo since it goes under 20hz?? i want a simple vco/ lfo to controll some of my guitar effects via there expression jack

[@abinsha8264]

Cann we produce the sound frequency in mega hz???

[@dallasjames8610]

kill the music

[@kensrocketry2785]

Can you use this circuit to oscillate a current and power a transformer and get a higher voltage at the end of the transformer?

[@indigogolf3051]

After you said "let's go ahead " for the tenth time in one minute, I had to leave.

[@kevinglassford7345]

What if you'd like multiple different wave form types?

[@bfbf6347]

is it possible to put in 2 1/4th input and out put jacks to turn this into a guitar pedal

[@joseaurelianosandovalgarci1884]

Can you add some other signal source over the principal frecuency?

[@chiragmodi5705]

how much frequency is generating?

[@jonaszkita8472]

hello keystonescience i realy like you films i wart to make an arc speaker but i got an problem i have no potencjometrs to make an tonem generator did i realy need tchem to make it? PS ewen of i have them i wil not use them (you no what i mean) [i have problems to speak englisch

[@KeystoneScience]

+ECHOP no problem, I made a video on a simple plasma/arc speaker, but it is nice to have to potentiometer so that you can tune it to the best frequency that will resonate easily , but I suppose you could likely do it without them if you want to calculate the correct frequency then use some math to calculate what resistance needs to go there to give you that frequency

[@jonaszkita8472]

thanx. Keystone Science :)

[@simionmusekiwa4877]

is it possible to use the circuit in an intercom system or pbx

[@MyCorn]

can this cancel out other frequencies?

[@Epicgamer559]

How would you make it 40khz?

[@jhankritsharma7303]

can I connect it to a small sort of speaker?

[@j.clowers7223]

Is it possible to get it to 58khz?

[@lordango]

Good videos You got a new subscriber!

[@abhimanyujyani973]

hey buddy i have a question can we reach the range of ultrasonic wave frequency answer me as soon as possible please

[@KeystoneScience]

+Abhimanyu jyani theoretically yes, I'm not sure how high it can reach, but defiantly in the ultrasonic range

[@abhimanyujyani973]

so mate can you tell me what should be the range of potentiometer and the capacitor and the resistor i mean there new values for ultrasonic

[@navinlessing7053]

to what frequency is this circuit

[@velvetmusic9851]

What a great channel!

[@Morbrek]

Also can this generate tones we cant hear? And if so. How do we monitor those?

[@Morbrek]

Im thinking in the range of Dog training. IF i can create tones I can hear but dogs can. And I set this up to be a button push scenario. I could train a dog to respond to a push of a button.

[@sergei5161]

yes you can

[@trevorwovz6614]

didnt understand anything you said, but it was pretty dope

[@KeystoneScience]

Hahaha thanks xD

[@athp]

Thanks for the videos

[@meghjitmajumder3468]

Wow, nice video....I'm wondering that how can I use it to make a cell-phone jammer?

[@DI-xe8vq]

this is a tone generator

[@mal5256]

@@DI-xe8vq lol

[@franzkardel4987]

Maybe you can try connecting it on a phone charger at very high frequency , charge a phone , and there expect what will happen .

[@underverser]

The music is awesome...

[@stonecold7945]

What is the point in the .01uf capacitor.

[@defaultuser000]

Stone Cold7 It's connected between pin 5 of the timer chip and ground. Pin 5 is the "Control Voltage" pin. This is the reference voltage for the comparator on the threshold pin. The small capacitance from pin 5 to ground helps to stabilize this reference voltage for more stable operation.

[@upenderRana9]

thats amazing also

[@larryland2462]

AWESOME..

[@N1650andTheCPG]

where do u get this stuff i want to start trying it :)

[@hebitsukai9830]

write to me to [e-mail], i ill sent you the beguinners guide minibook - Forrest Mims

[@lopezstallon8449]

wonderful..... works fantastic

[@KeystoneScience]

Great to hear :D when I use mine I only power it with 3v and that works better I think

[@lopezstallon8449]

+Keystone Science ....what are you thinking next to build?

[@KeystoneScience]

+lopez stallon to be honest I'm not too sure, I usually procrastinate until Tuesday then film and edit it to post on wednesday, any ideas?

[@lopezstallon8449]

+Keystone Science Hmm.....how about a gyroscope or a electromagnetic levitation device or a static electricity generator?

[@KeystoneScience]

+lopez stallon those all sound pretty cool, I think I will try to make one :D

[@jonaszkita8472]

i hate auto corect XD

[@travisduggins]

❤

[@marellazalameda9862]

IS IT POSSIBLE TO PRODUCE 1Khz to 20Khz tone from this circuit?

[@KeystoneScience]

+Marella Zalameda yes

[@KeystoneScience]

+Marella Zalameda by manipulating the capacitor and resistor, you can probably get up to 500 kHz for this 555 timer

[@marellazalameda9862]

The capacitors u used in the video can produce 1kHz to 20Khz frequency? Say, I will not change anything u used in the video I'll just use exactly the same components from this video I will be able to get 1kHz to 20kHz?

[@marellazalameda9862]

I want u to know that me and my thesismates would want to use your design as a part or our prototype for our research about using frequency to delay ripeness of fruits, I will put credit by your name.

[@izapataet4709]

how about 400-800hz?

[@darkenergy2861]

How to measure the Hz

[@walkerdeserttracer6767]

Dark Energy look at your ruler. one side should have inches and centimeters, the other side should have Hz.

[@snaprollinpitts]

electronic circuits can be visualized by the use of schematics, try to use them next time, it makes for better understanding of the circuit you are explaining.

[@MrWeezy479]

Where can I get these materials? Please help...very urgent. Mother has cancer and our last resort is trying resonating frequency to destroy cancer cells.

[@TheJestar30]

Exactly what I am looking to make..what would you do to extend the frequency range higher? Or lower? Thx bud

[@alexeyegorov2036]

Use or experiment diferent capacitors into the 4.7 capacitor plot.
