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
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.
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.
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
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.
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.
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
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.
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
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!
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 ...👍👍
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.
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 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.
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 =)
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.
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
Another great video 👏 👏 Look forward to watching your videos as they're so well made,keep it up look forward to the next installment,have shared this to twitter hope thats ok? Also recommended your videos to lot of collegues Well done & thanks👍
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?
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
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 :)
Can you also explain oscillators with variable frequency, which are stable (keep the same waveform without attenuation or distortion) throughout their whole spectrum?
1:25 I don't really understand how the capacitors get charged alternatingly. Unless I'm overlooking something, the circuit is perfectly symmetric, right? So by my logic, C1 and C2 should get charged at the same time and should then activate the transistors at the same time. Also, how does C1 discharge exactly when transistor Q2 is conducting but not Q1? Through the base of Q2? If there's still someone who reads these comments, please explain! Thanks!
I would say that this is the reason. Have you understood the rest of the circuit? (LC tank, feedback) I have difficulty understanding how the feedback works here.
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 there, i was trying to reproduce the circuit in 1:43, but a big confused by the polarity of the capacitor. why is - side of capacitor connect to 9 V?
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.
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?
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.

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
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
One of the best videos on youtube about oscillators. thank you!!
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
Thanks Scott, Im learning a lot from your videos, much appreciated.
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.
I like this series .
+Parker John I like this parallel
+le jokur so bad it hertz
Ohm y god I hate these jokes...
+RandomVideos Let's not get too amped up ubout this.
+Marrus Q I just can't resist.
Well done! You managed to cover a lot of oscillator theory in a nice little video. A must see for beginners or oscillator nerds :)
This oscillated my mind.
Thanks
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.
best one basic video yet greatscott! learned a ton!
+Cris G Awesome!
thanks for all great information you give it to us i from egypt
A lot of that went over my head. I might have to watch this video a couple more times
your videos are the best electronics tutorials on youtube. if only you didn't have an accent... nothing's perfect i guess.
woow so much information to assimilate if you're not really involved into such electronics
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.
Great intro to oscillators ... makes high frequency oscillators look a lot less scary now!
Finally! That LC circuit I made at uni makes sense!
Would love more on the crystal oscillators
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
Tbh the only video I found it answer my question
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.
you just made a analog synth 101😎
alhamdulillah.. I got the clearly explanation.. thanks mas bro

The capacitor determines the frequency range. Higher = Lower frequency range. I used a 10uF capacitor and my range was 1-200Hz.
If I only had a fraction of your knowledge I would be a happy man. Keep the videos coming 👍🏻
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
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.
Perfect for a bicycle lighting system :)
THanks for the great tech bite...Always enjoy these videos!
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.
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
your videos helped me a lot in electronic basics, thanks a lot man.
It's a very nice video, much appreciated.
Love your videos man! Wish i had your workshop so i could try all these things
I like your all electronic videos
very informative and efficient time usage
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!
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 ...👍👍
would you make a video about how to measure inductance?
Sure
LCR meter
ruclips.net/video/uU2KqXwQ16c/видео.html
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.
You can measure it using a Maxwell Bridge, its a null type AC Bridge that measures the inductance and also the resistance of an Inductor (quality)
good video great scot i learn a lot of your video's
So beatiful, thak you, from México City
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 was lost right after he said, "if you ever tried to find out..."
Bro...baffled...i got some crystals...i just need an electronic voltage reader/creator withing the crystal range....Simples!!!
Ahaha I was just about the write the exact same comment 😂 either that or, “You lost me at 0:00” 🤣
@@JaydenLawson LOL
😂
The 555 Timer is a versatile device making it simple to make oscillators and others.
You're more didactic than my professors in uni
Wie man sofort hört dass du deutscher bist ^^
Aber sehr geile videos machst du, respekt
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 =)
I learned more in one video than In one semester at school ,,😮
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.
Wow I Love it.😍🤩
But I suddenly think, How you become so great and know to make this circuits and make it work.
Can u make a video with it.
Thank u
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
That intro is pretty cool.
I find your videos (GreatScott) is much simpler to understand than afrotechmods. Still, both are good!
Another great video 👏 👏
Look forward to watching your videos as they're so well made,keep it up look forward to the next installment,have shared this to twitter hope thats ok? Also recommended your videos to lot of collegues
Well done & thanks👍
+Robert Thomas Thanks for sharing ;-)
+GreatScott! your welcome,did u ever think of writing a book?Just an idea 😉
Thanks again.
Super sir i learn some much from your channel do more videos sir
I am your fan sir
Nice and straightforward information as always...
Great job!!!
I used my computer into the "iCircuit." I could open my eyes, it's Forward Circuit. Thank you for Tutor. :)
+Michael Zajac Arrows indicate the direction of electron current flow.
i like the addition of the eagle drawings rather than the handwriting, sometimes it can be hard to read
good job :D
I just love your videos! Keep up the good work!
Great job sir.
very well explained

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.
I have idea for next video of this series : logic gate. Please I am very impressed about this.
Thanks .. good project
Can you make a video about the oszilloskop?
I like your videos, do so on !
+Noah Oertli I put it on my to do list.
+GreatScott! +1 again! 😍
love your videos man
+Rachit Shah Thank you :-)
Can you do a video on capacitor types and what each type is typically used for.
Please make a video about osciloscope, i find yours very useful. Thanks!
great video. good explanation.
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 :)
Thanks a lot man that was very helpful.
How can we increase the transmission distance ?? Do you amplify the inside wave or increase the power of the oscillator ?? Or in other ways
Amazing video!
Very well explained. Look forward to next time :)
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.
great job man, thanks
Very informative
Can you also explain oscillators with variable frequency, which are stable (keep the same waveform without attenuation or distortion) throughout their whole spectrum?
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.
Well done sir
1:25 I don't really understand how the capacitors get charged alternatingly. Unless I'm overlooking something, the circuit is perfectly symmetric, right?

i've been looking for a video like this, thanks!
Um, at 1:21 in the diagram are the wires between the base and capacitors joined or just crossing over?
i just wanted to ask how can i set the amplification factor please tell me about it!!!!
Could you do 3 pin ceramic resonators there pretty cool
awesome do you make a video on transistor oscillators by doing only crystal and only LC , RC
I want more in-depth analysis.
At 4:39, did he exclude the resistor on the collector side because of intrinsic resistance of the coil?
I would say that this is the reason.
Have you understood the rest of the circuit? (LC tank, feedback)
I have difficulty understanding how the feedback works here.
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 there, i was trying to reproduce the circuit in 1:43, but a big confused by the polarity of the capacitor. why is - side of capacitor connect to 9 V?
Could you talk about oscillation damping and where they could be used?
i learned a lot about the muscle movement of your left hand while you were covering up the drawings
