Thanks for the video, it clears up some of my confusion when it comes to tank circuits. I have always maintained that if you can learn one new thing every day, it will keep your mind active, and prevent age related deterioration. You sir, are keeping my mind young and active. Combine this with our desire to see new and wonderful things by traveling these United States of America, and I can stay young for ever!
awsome videos watching some of your older videos your english has actually improoving with time and more videos ,you probably dont notice it yourself,go watch your oldest video then your newest video you will hear it
I recently learned that you can make a square and triangle wave oscillator using a single op amp. It is simply an RC circuit in a comparator (I think that is what the configuration is). The capacitor determines the frequency range. Higher = Lower frequency range. I used a 10uF capacitor and my range was 1-200Hz.
great Scott, am a Nigerian ..learnt so much in electronics through your channel..though only the geeky can get along with your videos.. pls make a video about registers.. thanks
I built one simple Pearson-Anson oscillator. It creates a saw tooth signal with a glow lamp and was used in analog sound synthesizers. Glow lamps have also been used in noise generators.
Very nice and educational video. Oscillators are really fun to play with - blinking LED's, buzzers and tone generators, high voltages and flyback oscillators, spy bugs and so on fun stuff that's easy and fun to make.
Out of all the things I've learned about electronics... the biggest thing by far... I need an power supply/oscilloscope. Thank you for this video though, very informative.
One of the best video on oscillators other than electroboom But you could have made it more long. Please make a very long and informative video on oscillators. Please. It's very important to understand. Thanks
thank you so much. this video is exactly what i needed right now. im currently studying oscillators and was having a bit of hard time wraping my head around things. please keep this series. thanks again.
+Dragos Puri More than "short", I'd point out that it leaves little room between complex sentences. I advise the author to slow down a little bit on the explaining, at times.
Can you make a video where you show in detail how to use the oscillator at 4:39 and how to vary the frequency with audio. Also how to make a FM transmitter.
I just come across this video. But I have a little question about this oscillator circuit like LC or crystal oscillator... Can any one of this be used with an inverter circuit to produce since wave at 50Hz?
Great video. I don't know anything about this kind of thing. But for whatever reason I woke up and wanted to know exactly how a radio works. I looked at page after page, video after video that just told me that a carrier wave has a modulated wave blah blah but no one mentioned anything about how the carrier wave was made. After a few hours I was yelling at the screen WHAT MADE THE CARRIER WAVE, GOD? MAGIC? Anyway, thanks, this video explained a lot about how waves/frequencies/etc are created in the first place. :)
i thought crystal oscillators were some sort of a fancy capacitor. Now i have something thats knteresting in my parts box now. thanks for the explaination!
I am doing RLC circuits with timing applications in my circuits class and timing with E clock and input/output compare functions in my microprocessors class now so this vid is perfectly timed(pun intended) for me now.
Apply a known high frequency square wave with a known voltage and measure current flowing through it, then you can calculate the freq. by using the coil reactance formula backward.
Hahaha. To be honest, as a german learner for 2 years now I didnt get it until I saw your comment. So that's not that of a thick accent in my opinion. tschüss =)
thanx for the info .. but realy how are you .. you are genius .. i love your work .. i dont stud electronics .. but i learn alot from you ..keep the good works on ...👍👍
با این که رو این مدار اسیلاتور هنوز کار میکنم و هنوز موفق نشدم ..با این وجود این کلیپ یکی از بهترین کلیپهای آموزشی است.دیگر کلیپهای موجود در یوتوب هر کدوم یک جورایی بدرد نخور است مثلا یکی نقشه ندارد یکی فقط لحیم کاری را نشون میده یکی یکسره فرمول ریاضی در مورد اسیلاتور نشون میده و فقط تئوری میگه که یه قرون نمی ارزد...خلاصه این کلیپ و این کانال کارش درست هست علاوه براین که زبان انگلیسی این بابا خیلی خوب و واضح است
Can you also explain oscillators with variable frequency, which are stable (keep the same waveform without attenuation or distortion) throughout their whole spectrum?
Scott..can you explain,what is the purpose of 555 timer in the mobile signal jammer..what kind of result that ic give outside in the mobile signal jammer.
Hi! One query: I have to perform an oscillator to maintain a QCM at its resonant frequency which is 10 [MHz]. I could use the last circuit you showed but I don't understand how to choose the components according to what the resonant frequency is. Very good video. Greetings from Argentina.
Thank you so so so so much! Your videos are excellent, and I finally got the astable multivibrator working!!! :))) Keep making more awesome videos!! Thank you so much =D
frm .01Hz to 100 khz a Wein Bridge oscillator does not require inductors; it is made with 2 matched resistors and 2 matched capacitors and can use a incandescent bulb to maintain its amplitude with very low distortion. It can even be made using a variable dual capacitor allowing the frequency to be varied by a factor of 10 !
What viewer like myself and many others here are trying to say, is we want to build these circuits with you while you explain them. Watching you go through something are are already very familiar with, does not do anything for your viewers. We learn best by doing, not watching someone else do something.
It could be very-very interesting if you explain how LC- and crystal amplifier circuits work, it's not quiet obvious from this video. Anyway - thanks for your great tutorials :)
Thank you for this video, I used the topology at 4:39 for the colpitts and it works perfectly. However, I cannot really grasp how the LC tank is formed (inductor is not in parallel with the two capacitors), and how the output of the LC tank is connected to the input of the amp ( I don't see a feedback path going to the base of the bjt). Could someone please briefly answer me those two questions? Thanks
Great video. I need to create a 2khz oscillator to drive a buzzer. The frequency must be stable at 2khz and must support head and a voltage between 10-16 volts without changing much. Do you know witch would be the right oscillator circuit to achieve this task?
Please go more in depth about crystal oscillators and temporary construction methods better than a breadboard that performs well despite the high frequencies.
Two things: The "Great Scott" button in the bottom left is very hard to click because of the bottom bar for play and pause etc, might be better to move it to the top. Secondly; could you try turning a wind up torch in to a wind power generator? I'm building one currently to see if I can light up a garden light, I want to know if you can do it better because mine can't run of very light wind. Thanks!
Will a tank circuit feed with pulses of one polarity only, have a backrush of a induced voltage going in revers direction of the feed polarity, and if this current is captured is this what is considered an constant currant supplying device?
Because the crystal sets the micro controller speed, does that mean that if I changed the crystal I could change the speed of micro controller and if so, assuming there would be limitations how much could the speed be changed?
Yes. It's essentially what happens when you overclock a CPU. The device might function at a slightly higher speed, and increasing the supply voltage can increase this maximum, at the cost of higher heat output and a shorter lifespan.
Eventually if you overclock too much the crystal will resonate faster the processor can compute, leading to incorrect calculations. It might only be half-way done with its multiplication operation but the crystal ticked and now it saved an incomplete value. Generally you'll have very little overclock room before you get incorrect calculations, since they already calculated the highest valid frequency for you.
What stops the capacitors from discharging at the same time in the first oscillator circuit? Because the 47k resistance is the same on both, so would they not charge at the same rate?
Thanks for the video, it clears up some of my confusion when it comes to tank circuits. I have always maintained that if you can learn one new thing every day, it will keep your mind active, and prevent age related deterioration. You sir, are keeping my mind young and active.

Ahh the good old 555. THE Gateway drug to pal's, gal's, pic's, avr's, cpld's and ultimately fpga's. Good luck with that build up ;)
devjock , I know it took three years to read your joke, but it's a hoot! LOL
@Caiden Mateo Can someone say bot?
Congratulations Greatscott! Really great, especially for someone like me who's just getting again into electronics.
Me too
You SIR are the new teacher that I am following ! Rekindling my physics and electronics that I lost while learning medicine ! THANK YOU SO MUCH
awsome videos watching some of your older videos your english has actually improoving with time and more videos ,you probably dont notice it yourself,go watch your oldest video then your newest video you will hear it
your videos are the best electronics tutorials on youtube. if only you didn't have an accent... nothing's perfect i guess.
One of the best videos on youtube about oscillators. thank you!!

great Scott, am a Nigerian ..learnt so much in electronics through your channel..though only the geeky can get along with your videos.. pls make a video about registers.. thanks
The video of registers is already made: Arduino Port Manipulation
I built one simple Pearson-Anson oscillator. It creates a saw tooth signal with a glow lamp and was used in analog sound synthesizers.
Glow lamps have also been used in noise generators.
Perfect for a bicycle lighting system :)

thanks for all great information you give it to us i from egypt
This oscillated my mind.
Thanks
Thanks you for your time in making these video's. Somethings i understand but a lot is over my head. I still like to watch them. again thank you.
A lot of that went over my head. I might have to watch this video a couple more times
Out of all the things I've learned about electronics... the biggest thing by far... I need an power supply/oscilloscope.
Thank you for this video though, very informative.
Finally! That LC circuit I made at uni makes sense!
Well done! You managed to cover a lot of oscillator theory in a nice little video. A must see for beginners or oscillator nerds :)
Great intro to oscillators ... makes high frequency oscillators look a lot less scary now!
you just made a analog synth 101😎
You're more didactic than my professors in uni
best one basic video yet greatscott! learned a ton!
+Cris G Awesome!
Tbh the only video I found it answer my question
Would love more on the crystal oscillators
alhamdulillah.. I got the clearly explanation.. thanks mas bro
woow so much information to assimilate if you're not really involved into such electronics
If I only had a fraction of your knowledge I would be a happy man. Keep the videos coming 👍🏻
One of the best video on oscillators other than electroboom
But you could have made it more long.
Please make a very long and informative video on oscillators.
Please.
It's very important to understand.
Thanks
thank you so much. this video is exactly what i needed right now. im currently studying oscillators and was having a bit of hard time wraping my head around things.
please keep this series.
thanks again.
Pff .. finally i founded usefull video . Now i know how oscillator works thanks a lot ! God bless u 👋
I'll probably look at this a few times, great job.
I learned more in one video than In one semester at school ,,😮
THanks for the great tech bite...Always enjoy these videos!
Video is too short, and there isn't enough explaining done.
You could always watch more in-depth explanations at Khan
+Dragos Puri More than "short", I'd point out that it leaves little room between complex sentences. I advise the author to slow down a little bit on the explaining, at times.
+Dragos Puri he's wetting your appetite
+Dragos Puri Do a research then.
+Flaviu Hossu I will when necessary. But it's much easier when someone explains it to you.

very informative and efficient time usage
That intro is pretty cool.
So beatiful, thak you, from México City
i like the addition of the eagle drawings rather than the handwriting, sometimes it can be hard to read
good job :D
Love your videos man! Wish i had your workshop so i could try all these things
I find your videos (GreatScott) is much simpler to understand than afrotechmods. Still, both are good!
good video great scot i learn a lot of your video's
Wie man sofort hört dass du deutscher bist ^^
Aber sehr geile videos machst du, respekt

The intro forgets to mention oscillators for sound synthesis.
Nice and straightforward information as always...
Great job!!!
I have idea for next video of this series : logic gate. Please I am very impressed about this.
Can you also explain oscillators with variable frequency, which are stable (keep the same waveform without attenuation or distortion) throughout their whole spectrum?
4:30 I really wish you explained the amplifier part of the circuit-that’s what’s confusing to most people, not the tank circuit.
great job man, thanks

How can we increase the transmission distance ?? Do you amplify the inside wave or increase the power of the oscillator ?? Or in other ways
DMX: Digital Multiplex, commonly used in stage lighting. 255 values per channel, 512 channels per universe.
What viewer like myself and many others here are trying to say, is we want to build these circuits with you while you explain them. Watching you go through something are are already very familiar with, does not do anything for your viewers. We learn best by doing, not watching someone else do something.
Is there a difference between a rectangle wave and a square wave?
+Jamie Rollinson No. I noticed after recording everything that I used the two different terms. My mistake.
+Novislav Djajic Every wave has a duty of 50% if its proper
Homemade Laboratory not in pwm signals
Only in terms of duty cycle.
love your videos man
+Rachit Shah Thank you :-)
Super sir i learn some much from your channel do more videos sir
I am your fan sir
It could be very-very interesting if you explain how LC- and crystal amplifier circuits work, it's not quiet obvious from this video.
Anyway - thanks for your great tutorials :)
great explanation, thanx. but what to do with the oscillator once you have it?
+Dafuq Ucare As a start it is always fun to turn LEDs ON and OFF ;-) But I will show some other applications in future videos.
Thank you for this video, I used the topology at 4:39 for the colpitts and it works perfectly.
However, I cannot really grasp how the LC tank is formed (inductor is not in parallel with the two capacitors), and how the output of the LC tank is connected to the input of the amp ( I don't see a feedback path going to the base of the bjt).
Could someone please briefly answer me those two questions? Thanks
1) It is an LC series resonance circuit
2) The capacitor voltage divider is connected to emitter resistance, it acts as a negative feedback.
Great job sir.
Can you do a video on capacitor types and what each type is typically used for.
Great video. I need to create a 2khz oscillator to drive a buzzer. The frequency must be stable at 2khz and must support head and a voltage between 10-16 volts without changing much. Do you know witch would be the right oscillator circuit to achieve this task?

i learned a lot about the muscle movement of your left hand while you were covering up the drawings
Thanks .. good project
Hi can I use a mosfet driver with this? And power a igbt or mosfet with like let's say 16mhz to 64mhz
Two things: The "Great Scott" button in the bottom left is very hard to click because of the bottom bar for play and pause etc, might be better to move it to the top.
Secondly; could you try turning a wind up torch in to a wind power generator? I'm building one currently to see if I can light up a garden light, I want to know if you can do it better because mine can't run of very light wind.

If the micro proc. could function at higher clock speed, they would have used a higher freq. oscillator in the first
place.
great video. good explanation.
As always great video!!!
Very well explained. Look forward to next time :)
What stops the capacitors from discharging at the same time in the first oscillator circuit? Because the 47k resistance is the same on both, so would they not charge at the same rate?
I want more in-depth analysis.
