In this episode of electronic basics I will talk about how important oscillators are in circuits and how the three main principles work in order to create them. These are RC relaxation circuits, LC tank circuits and crystal oscillators.

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?
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!
Congratulations Greatscott! Really great, especially for someone like me who's just getting again into electronics.
Me too
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
😂
Thanks Scott, Im learning a lot from your videos, much appreciated.
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 :)
Perfect for a bicycle lighting system :)
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
This oscillated my mind.
Thanks
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
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.
Tbh the only video I found it answer my question
One of the best videos on youtube about oscillators. thank you!!
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.
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.
Finally! That LC circuit I made at uni makes sense!
You're more didactic than my professors in uni
best one basic video yet greatscott! learned a ton!
+Cris G Awesome!
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.
your videos are the best electronics tutorials on youtube. if only you didn't have an accent... nothing's perfect i guess.
alhamdulillah.. I got the clearly explanation.. thanks mas bro
Great intro to oscillators ... makes high frequency oscillators look a lot less scary now!
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
Would love more on the crystal oscillators
woow so much information to assimilate if you're not really involved into such electronics
It's a very nice video, much appreciated.
If I only had a fraction of your knowledge I would be a happy man. Keep the videos coming 👍🏻
Love your videos man! Wish i had your workshop so i could try all these things
would you make a video about how to measure inductance?
Sure
wzd leo Arduino lcd Transistor, capacitor, inductors (inductance) , and resistor meter!!
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.
I like your all electronic 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.
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 =)
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!
Pff .. finally i founded usefull video . Now i know how oscillator works thanks a lot ! God bless u 👋
So beatiful, thak you, from México City
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.
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! 😍
I'll probably look at this a few times, great job.
THanks for the great tech bite...Always enjoy these videos!
The 555 Timer is a versatile device making it simple to make oscillators and others.
I learned more in one video than In one semester at school ,,😮
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.
Let's get startedts
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
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.
That intro is pretty cool.
your videos helped me a lot in electronic basics, thanks a lot man.
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
i learned a lot about the muscle movement of your left hand while you were covering up the drawings
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
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?
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
very informative and efficient time usage
i like the addition of the eagle drawings rather than the handwriting, sometimes it can be hard to read
good job :D
good video great scot i learn a lot of your video's
I find your videos (GreatScott) is much simpler to understand than afrotechmods. Still, both are good!
Nice and straightforward information as always...
Great job!!!
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 ...👍👍
you just made a analog synth 101😎
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 just love your videos! Keep up the good work!
I have idea for next video of this series : logic gate. Please I am very impressed about this.
great job man, thanks
I want more in-depth analysis.
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 :-)
i've been looking for a video like this, 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 :)
very well explained
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
Well done sir
Please make a video about osciloscope, i find yours very useful. Thanks!
Super sir i learn some much from your channel do more videos sir
I am your fan sir
Thanks a lot man that was very helpful.
Very well explained. Look forward to next time :)
best than school ,
Amazing video!
Ouuu old introo legoo gotta be good
Can you also explain oscillators with variable frequency, which are stable (keep the same waveform without attenuation or distortion) throughout their whole spectrum?
As always great video!!!
You are the best
Awesome!
Great job sir.
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.
Very informative
Hi can I use a mosfet driver with this? And power a igbt or mosfet with like let's say 16mhz to 64mhz
Thanks .. good project
Great video! :D I really like these video series. Viele Grüße aus Nordböhmen. ;)
great video. good explanation.
Thank you I learned a lot!
nice video!
can you make a video on how to mecanically change the refresh rate on a multimeter? that would be nice!
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.
I would love to see you making a Knight Rider LED strip!!!
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.
Great video
excellent thanks man!
