I just realized you're using a Fluke Scopemeter - I had one of those at a job and it actually emitted noise oddly enough, I could get another piece of test gear near it and it would start effecting readings; that's how I found it. Yours looks like it's nice and non-invasive; why would I see that or what would Fluke do that is keeping it contained now?
You're a dang genius. I came into this video understanding the concept, but your free air circuit was a work of art, and your demonstration was so simple and to the point, and your explanation was so direct and "laymen's terms" that a five year old would understand the circuit. The car shock analogy was good, pretty much everybody alive can understand such a simple and direct analogy and IDK but a video like this teaches people how capacitors work in OTHER circuits and they may not even realize that they just learned it until they start playing around with another circuit and the information this video provided connects the dots in regards to that other circuit. Capacitors aren't "hard" to understand, but I think what makes it tough for people to get what they do and how they affect things is capacitance is easy to understand, but hard to explain. Because of this, a person new to the game may not get a clear demonstration or explanation of capacitors so it makes it tougher for them to grasp the concept. In all my years being involved with electronics, nowhere near your level, but an experienced hobbiest who makes a bunch of bespoke audio gear, one of the most common questions I get asked is what are capacitors all about. And this coil in this video also helps reveal some more esoteric functions of electronic circuits. Overall, I'd assume that pretty much any video you make would help anybody who does electronics on any level. ESPECIALLY that one you did where you described your shock experience and explained why safety is always the number one goal.
I'm a retired electronics tech. You've reminded me of how much I've forgotten. "Colpits Ocsillator". Haven't heard that sice tech school, LOL. I have a bunch of blue bread board, and an "Archer" printed circuit kit that I never used. Thanks for the refresher.
I love how old-school Mr Carlson is. Instead of using a nice little proto bread-board setup, he makes a network out of twisted end components floating in air like they did before the invention of the PCB.
We call this in the air circuit "dead bug" actually this is point to point. Dead bug came from flipping an IC over and soldering to its leads. The upside down IC looks similar to a dead bug.
Indeed. Someone at Hackaday wrote that only professional product presentation is fit for display. Wow, that writer there obviously isn't a tinkerer or inventor, much less a hobbyist, dare say hacker.
I like having my memory refreshed since it has been a very long time ago that I actually did any real electronics work. (The last time was the early 80's at Texas Instruments)
@Falcrist "It's not just a good analogy. " NO, it a crap analogy since, as leouvarouv pointed out the analogy of the damper is resistance, which he is not even discussing. TOTAL fail on the analogy front.
A shock absorber, especially a gas shock has energy storage potential, a resistor does not have the ability to store energy, other than a secondary action known as heat from power dissipation, IE: The body of the resistor may store heat for a period of time. A capacitor takes current to charge, then when it discharges, it supplies current, making it oppose change. This is exactly what a shock absorber does to damp the movement, it opposes change. The shock absorber will also smooth the ride, reducing the bumps. A resistor will not have that affect, as it does not have the charge and discharge "pump action." Another way to see this: In a power supply, a capacitor will reduce bumps right to pure DC, this is also known as a "smoothing capacitor" or reducing the ripple, IE: the ripple being bounces of the car, "smoothing the ride." Now this could be looked at as reducing amplitude, but in this demonstration, you can clearly see it is reducing the frequency of the oscillation on the oscilloscope, much like the shock absorber does in the car, reducing the number of bounces or oscillations. Hope this helps. Merry Christmas!
You know you are a geek when a title and picture like this for you is considered Click Bait 🤣. I was like "I think I know, but now I am not so sure, I must find out!!" Love your channel! thank you so much for taking the time to share all you knowledge!
Concerning Clickbait : I thought the coil in the picture was a resistor, so I thought the inductance in the picture are apparently supposed to be the small windings at both ends of the capacitor... Also because the big green arrow is almost pointing at it... So I said to myself : "No no no... this can never work what is this guy up to?" So I watched the video and there you have it Click bait but probably not intentional. Wouldn't have hurt further to show the formula w = 1/sqrt(LC) Then you can see directly that the freq drops when C (or L) increases.
No the device itself its an inductor. As mentioned on this, like was said about inductors and resistors their color and texture that's an industry standard, so its known what device it is. Electronics comes in many forms and styles.
I grew up broke barely able to afford popular electronics magazines. This is a golden age. 👍 Curiosity mixed with a bit of formal education has brought employment. Thank you.
Just be aware of the self resonant frequencies of your caps and inductors. Especially inductors. Frequencies near or above Inductor self resonance will cause the inductor to drastically change from spec at those frequencies. Many engineers miss this when using square or trapezoidal shaped waveforms since there might be frequency components (3 to 7th harmonic) that go past the self resonant frequencies and don't play nice with your circuit. If you're in the sub 10 MHz for your highest frequencies, then you generally don't have much worries. I would be great for this channel to devote some time to this as filters get designed from common equations but don't consider the resonant frequencies or how to build circuits around these limitations. And to the curious, there are physics limits that put hard requirements on the resonant frequencies of inductors that you can't just spec a higher quality part to get around it.
This is cool, some of the stuff we got in basic electronics and electricity in the Navy. Basic oscillators, learning the circuit, then troubleshooting a bad circuit to find the faulty component.
I was just going over some inductors for designing some RLC filters for audio equalizers for the highest quality performance possible and the nice mole hump they produce between the roll-off corner frequency and base line source signal. When I enrolled in college for an engineering degree 15 years ago, unfortunately online resources were a pittance compared to today. We're at a point now where Udemy, SkillShare, Kahn Academy etc. should really be accredited but obviously the mainstream schools don't want the competition. Literally a 20 dollar course replaces 3 grand in credit hour classes.
I have just started my journey into the land of the magic smoke, i am like that thing looks like a resistor. Imediately adressed in the video. Nice work!
This was most interesting and timely. I've been reading about the matching network needed for an Inverted L antenna on 160m. Your explanation was helpful in understanding the network needed for my antenna. Now, if I can just find the parts needed. Thanks for sharing your knowledge with us.
I'm mostly at a loss for what you are doing. I know only the most basic ideas about electronics yet thoroughly enjoy your lessons. I cannot wait for more videos. Until then, I'll browse through your library. Cheers!
9:15 I was thinking about a shock absorber then you immediately mention it 😊 Also it's like a fuel rail in a car using a fuel dampener to buffer fuel PSI oscillations.
Component level analysis. All of the little important things not always considered. Especially liked the relay vid showing the spikes from the coils when the circuit is opened. Gives some insite into a t.v. flyback with the calapsing magnetic field and the roll of the Damper.
Hi, this is a nice video and demonstration of the theory of an LC circuit. For a more practical example, I have been building LC tank circuits to have more AM selectivity and (DX) ability to listen to far off AM radio stations. I use only two components. First, I have a 3-350 pF variable capacitor in parallel with a Litz antenna wire coil. The Litz wire provides great radio frequency capture capabilities and I can tune the antenna to various AM radio bands to help eliminate noise. So, your video has real-world uses!
very enjoyable, thanx. 👍 here i was thinking as you talked through the lc circuit using the shock & spring analogy “ok now we stick in a R for a RLC ckt to damp that oscillation down to zero just like i would adjust the ports on a physical damper”. i’ll have to start playing with clean stuff again. beats getting down on a creeper in my 70s. 😄
Great tutorial! This is where a buffer transistor/FET helps greatly with pulling the oscillator at least in a VFO type circuit. On another note I greatly appreciate you teaching in the analog realm using discrete components many times. In my opinion a lot of learning happens this way. Merry Christmas sir.
I converted a small reel to reel 3" tape recorder from DC bias to AC bias by building a 30 khz bias oscillator. Output is 55 volts peak to peak from a 9 volt battery. It was a cool experiment and it sounded better with recording music where as before it was only good for voice. I have a few antique things I did experiments on.
I noticed using DC voltage this circuit produces a nice sine wave with a very close to 50/50 cycle. That’s awesome, I was in junior college back in the 80’s took electronics technology course and my instructor was attempting to produce true sine wave at 60 hzto run appliances known now as an inverter. I built a “Time Machine” I am going to bring him this circuit, thanks a bunch 😂
These "Tech Tips" are a marvelous way of seeing the knowledge first hand, thanks Mr C. The "Tip" about the coil/resister difference in shine was gold. Great instruction..👍👍
Merry Christmas to you and yours, Mr. Carlson. I've been enjoying and learning from your videos for many years now. Looking forward to a new year of electronics learning fun.
When I was 12 years old I built my own 60 wpc stereo from Allied radio. They suggested putting a 100 microfarad disc capacitor (I think that was the correct value) across the speaker terminals to eliminate Spuris noise. And now, 50+ years later, I finally understand how it works! The voice coil in the speakers is the inductor! whoda thunk...
Mr. Carlson really brings out the basics of learning rather complex topics in a fun and reinforced way. As a retired graduate engineer, I recall learning basic electronics as a low-life assistant to an electronics repair tech when in high school back in the 60's. Although I did not understand or was aware of the STEM behind the decisions the tech used to both troubleshoot as well as repair/modify gadgets, I was well prepared when I started college to make sure I learnt the fundamentals rather than just get through the class for grades
This "Tech Tips" series is really very helpful to electronics knowledge especially for radio amateurs like me. Please if this matches to this series, include a video about the choke (inductor) between the two smoothing electrolytics, into vacuum tube power supplies. How exactly works. Thank you for all the goods you offer us.
No bugs were harmed in the making of this video. 😉 I'm getting close now, to physically experimenting with Esaki LC Tank Oscillators, as controllers of various parameters in audio effects boxes- Ge Transistor fuzz, inductor-based filters, diode clipping stages, and a lot more, for the purpose of processing synthesizer sound, drum machines, samplers, etc..Heck, guitar too, if a guitarist wanted. I'm not a guitar guy. I've been making music with electronics since 1985. I was recently able to buy a very small handful of early 1960's General Electric germanium-based tunnel diodes, completely gold-plated, at a lot cheaper price than usual. With those, I also received a few less rare Esaki units, but more importantly, they are silicon, which if I understand correctly, are more durable than the Ge units, which seems like a good place to begin experimenting. Since I am new to Esaki diodes, It seems wise to work with the Si, before venturing into any of the rarer, more expensive Ge units. Thoughts, Mr. Carlson?
LOL, it's been a while since I seen you last Carlson. looking like you shocked your self with hi voltage caps a couple of times, lol. Hay I just wanted to thank you for your inputs and answers on Patreon, when I was asking you questions on a repair job I was doing. it helped me get it done. you were there whenever I asked questions. thanks again.
I made a bug with a tuned LC circuit one time had a wrapped air coil I could crudely chang the freq. by pushing the coil tighter or pulling it apart . When I hit my receivers set freq. it would squeal. I could also change the Cap. because it was adjustable. fun project from Harry Lythall
Hi, looking at your well explaining video, I wondered if little DC motors 3-6 or 12 V, which have a capacitor over their connections, would benefit from adding an extra coil when running at lower voltage (and moving up). I mean start running at a lower voltage or start running smoother. Just a thought...
4:45 That free-air stuff reminds me of the old days of Point-to-point wiring on lugs, inside a shielded chassis. Big, meaty caps, coils, resistors that a MAN could really get behind, like working on a small-block Chevy.
The spring is the shock absorber in a car. The other main component is the DAMPER. So called because it dampens the natural oscillations of the spring and weight attached. Otherwise a great video, thanks for uploading.
In education they call this a “A real-world example is a concrete instance from actual life that makes abstract ideas or concepts understandable, showing how they work in practice…”
Been watching for a while...top notch...wish i lived much closer Mr Carlson.... you'd need patience... I've just bought a lovely ts930....... totally love the show Mr Carlson
Hmm - Great video - I have an old handwired Fender Guitar amp. The schematic shows that each of the 4 diodes of the rectifier has a .002 uf capacitor. -- Is this to filter the DC voltage before it enters into the filter caps -- Which also further filter the power -- That is going to the preamp and power amp sections -- i.e. circuits and tubes?
Thanks for another informative lesson. I liked the mechanical spring analogy to illustrate the LC network. I also liked the Christmas tree graphic at the end of this video. Merry Christmas from one Paul to another! 73 de W2PND
Howdy. Very nice. About these miniature coils. I have observed some stop working at uhf frequencies. I would assume this is because the ferrite slug does not reach that high and the inductance fades out. I wonder whether there is a way to determine how high the coil reaches. Does it go beyond the specified resonance frequency ? Manufacturers do not specify used ferrite material. Knowing the material it would be easy to check the bandwidth. Cheers.

This idea resonates with me.
I see what you did there :^)

Are you trying to wind us up ?... we might have to incapacitate you !! 😂👍
@peterfitzpatrick7032 I like that
Those tech tips are what brings people to electronics, also are always fun to see various circuit behaviors.
I would never have guessed that was an inductor!

I like having my memory refreshed since it has been a very long time ago that I actually did any real electronics work. (The last time was the early 80's at Texas Instruments)
Spring and shock absorber... Interesting analogy, much easier to explain than how the components release stored energy to non techies.
It's not just a good analogy. The same concepts have been applied directly to mechanical systems in the design of tuned mass dampers and inerters.
I think a resistor is a shock absorber. Both a capacitor and a coil are "springs" (they absorb energy and then they return it).
@Falcrist "It's not just a good analogy. " NO, it a crap analogy since, as leouvarouv pointed out the analogy of the damper is resistance, which he is not even discussing. TOTAL fail on the analogy front.
@tuberroot1112perhaps if you watched the video first...

That's interesting. It sounds like some components will corrupt the circuit if it resonates at that component's self resonant frequency. Is this true?
This is cool, some of the stuff we got in basic electronics and electricity in the Navy. Basic oscillators, learning the circuit, then troubleshooting a bad circuit to find the faulty component.
Now I understand how a variable capacitor works in a radio! lots of useful information here

Snub or oscillate. The spring/shock absorber analogy is slick.
The tech tips series is awesome!
The quality of everything Mr. Carlson puts together is incredible. Where I simply solder wires together his is wire wrapped to perfection.
Great video Mr Carlson sir you are awesome thanks and happy Christmas 🎄 ❤❤❤

Thank you for this Mr Carlson, rare to come across someone who is so knowledgeable on valve and solid state. G uk
great stuff as always Uncle Paul, wishing you a lovely Christmas and New Year
Brilliant explanation. Awesome analogy with the shock absorber/spring
Instructive and interesting and I also like the subtile puns mr Carlson does.
Nice oscilloscope collection! I had the one one off from the upper right for a while until I had to move
I love your videos, not sure why I have gone so long without subscribing. Subbing today :)

Very interesting indeed. Great series of tech tips. Great stuff, thanks very much. Take care and happy holidays
I love your analogy. Well done!
Thank you for your very informative videos, I love what you do
Very interesting and enjoyable series!
Nice stuff😊
9:15 I was thinking about a shock absorber then you immediately mention it 😊
Also it's like a fuel rail in a car using a fuel dampener to buffer fuel PSI oscillations.
I was thinking it's a good thing you're not crazy because you would be a dangerous mad scientist lol HAPPY NEW YEAR SIR
Nice mini tutorial... Thanks!
Thank you for the Great Video.
I am impressed by the stability of the oscillator 😊
Component level analysis. All of the little important things not always considered. Especially liked the relay vid showing the spikes from the coils when the circuit is opened. Gives some insite into a t.v. flyback with the calapsing magnetic field and the roll of the Damper.
Awesome ,Thank You.

My first thought was a resonant band pass or notch filter. Nice analogy BTW.
I converted a small reel to reel 3" tape recorder from DC bias to AC bias by building a 30 khz bias oscillator. Output is 55 volts peak to peak from a 9 volt battery. It was a cool experiment and it sounded better with recording music where as before it was only good for voice. I have a few antique things I did experiments on.
Mr Carlson is the dude
Awesome video, thanks. Long live radio!
I noticed using DC voltage this circuit produces a nice sine wave with a very close to 50/50 cycle. That’s awesome, I was in junior college back in the 80’s took electronics technology course and my instructor was attempting to produce true sine wave at 60 hzto run appliances known now as an inverter.

good way to look at things
Parabéns ótimo vídeo, eu já me inscrevi, abraço

Good morning sir ji Thanks 👍
This "Tech Tips" series is really very helpful to electronics knowledge especially for radio amateurs like me.
Please if this matches to this series, include a video about the choke (inductor) between the two smoothing electrolytics,

I will do a video on the "Pi filter" soon. Thanks for your kind comment!
No bugs were harmed in the making of this video. 😉
I'm getting close now, to physically experimenting with Esaki LC Tank Oscillators, as controllers of various parameters in audio effects boxes- Ge Transistor fuzz, inductor-based filters, diode clipping stages, and a lot more, for the purpose of processing synthesizer sound, drum machines, samplers, etc..Heck, guitar too, if a guitarist wanted. I'm not a guitar guy. I've been making music with electronics since 1985. I was recently able to buy a very small handful of early 1960's General Electric germanium-based tunnel diodes, completely gold-plated, at a lot cheaper price than usual.

Excellent! I've been doing electrical troubleshooting for 45 years! Just came across your channel ... Love it!
Welcome aboard!
Beautiful explanation !
Many thanks!
Excellent shock absorber analogy
the shock absorber act like a parallel resistor not cap . cap is analoge of mass of the car .
In education they call this a “A real-world example is a concrete instance from actual life that makes abstract ideas or concepts understandable, showing how they work in practice…”
We live for tech tips.
I find all the various oscillators and tuning strategies endlessly fascinating. I really appreciate your focus on them, Paul. Merry Christmas!
Merry Christmas to you as well!
Been watching for a while...top notch...wish i lived much closer Mr Carlson.... you'd need patience... I've just bought a lovely ts930....... totally love the show Mr Carlson
Thanks 👍
excellent demonstration
Thank You!
In deep masterring electronics It goes often in the Little details, 4 good working and lasting Long Time.
Hmm - Great video - I have an old handwired Fender Guitar amp. The schematic shows that each of the 4 diodes of the rectifier has a .002 uf capacitor. -- Is this to filter the DC voltage before it enters into the filter caps -- Which also further filter the power -- That is going to the preamp and power amp sections -- i.e. circuits and tubes?
Thanks for another informative lesson. I liked the mechanical spring analogy to illustrate the LC network. I also liked the Christmas tree graphic at the end of this video. Merry Christmas from one Paul to another! 73 de W2PND
Merry Christmas to you and yours as well!
Love the tech tips.
Thanks Don!
mr. carlson is the real deal I have been into electronics fourt 56 years 20 years professional , and I have learn a lot from his videos !
Thank You for your kind comment! Have a Merry Christmas.
I am love electronic
As an older circuit instructor, I enjoy your well thought out demos.
Thanks for the kind words!
That's twice in 2 videos I've learned something new!!. Didn't know that about inductors 😮
That's great to hear!
Howdy. Very nice.
About these miniature coils. I have observed some stop working at uhf frequencies. I would assume this is because the ferrite slug does not reach that high and the inductance fades out.
I wonder whether there is a way to determine how high the coil reaches. Does it go beyond the specified resonance frequency ? Manufacturers do not specify used ferrite material. Knowing the material it would be easy to check the bandwidth.
Cheers.
Merry Christmas Mr Carlson !
Merry Christmas!
