Thank you so much, I am so glad to hear this. Really appreciate your comment ❤️❤️❤️❤️❤️❤️

It's his use of English.. it is clear, concise and at a very consistent speed

@@elewizard Your English is so clear that you made a double purpose: help me to train my ear to understand better English talk, and at the same time to learn electronics... Thanks a lot! You have gained a new subscriber! Greetings from Argentina!😄

Those bread boards are the best!

​@@elewizardi love working on electronics. I have done it for many years. When it comes to components, mostly just replacing, or following a diagram to build a circuit. I have always had trouble designing circuits. Mostly not 100% understanding the uses and why/how.i just discovered your channel today and have watched a few. I now understand why i have used the components that i have, not just because it is what the instructions say or what was there and broken. I just want to say thank you and keep it up.

Glad to hear that, I am so happy for motivating you, 🥂

Glad it was helpful! Thank you for sharing and watching

Thank you so much ❤️❤️❤️❤️

Glad it was helpful! Cheers 🥂

Thank you dude, not because of your support, but also because of your kindness 😉

Glad it was helpful 😃 I will try to make more videos of this type 👍

You're very welcome! Cheers 🥂

Hi my friend. Glad you think so, accept my warm welcomes from ardabil

@@elewizard Thank you sir. Benım anne tarafim de Ardebidiler. Sağolun abi.

My pleasure 😊

Glad to hear that 😃

You are welcome!❤️❤️❤️

Touch sensors can be made by using several different methods. Now you learned one of them 🍻

Yes it's like sales people that read from the back of the box, but this is all very interesting. I guess there is an attitude to things that, nobody expects anyone to use a soldering iron any more.

Thank you 🙂

Noted! Thank you❤️

More to come!

Thanks for watching and for the encouraging comment! Your support motivates me to create more content!

Thanks and welcome ❤️❤️

My bad 😁

You are most welcome

Thank you my friend for encouraging me ❤️❤️❤️❤️ BTW, gratitude for the £2 Super Thanks support! 🙌

You are very welcome ❤️ Thank you for the point

You are most welcome ❤️ I will do my best

Thanks for sharing❤️

Photovoltaic couplers are generally pretty slow and the last time I looked (years ago) they were quite expensive. Still, they are a good solution for some applications.

I grew up with LM7805 😅

Great regulators.

Experience, that is the key 🗝

So glad you think so

Keep watching❤️

Thank you dude, keep watching ❤️

Thanks for watching!😊

Keep watching. And I will keep improving my accent and speech 👍😊

So nice of you 😊

Yes, it is in my todo list 🙃

@@elewizard waiting for it

Good points, the circuit is not high precision, you have to add some other components to make it more precision. Components like OPAMP. I will explain it in one of my upcoming videos 👍

Wow, thank you ❤️❤️

Thank you! Cheers!

Glad you think so!

Glad you enjoyed it

You are most welcome

Thank you so much ❤️

Thank you too my friend ❤️❤️❤️

Thank you so much

It is my pleasure to help you ❤️

Thank you so much my friend ❤️

Glad to hear that

Will try 👍

Thank you ❤️

Not yet 🙃

Thanks

Thank you for the point

You're welcome

😃

I had one, but it is not available now 😉

it depends on the load, the load may need a resistor or not!

@@elewizard Thanks, I see that, but won't a load such as a motor vary in impedance at different speeds?

@@Enigma758 A common collector (CC) amplifier or "emitter follower" is a good circuit to use when you want to apply a constant (but variable as required) voltage to a load that varies in impedance. Remember that an ideal voltage source has zero output impedance - the voltage stays constant no matter what current is drawn from the source. The CC amplifier has high input impedance and low output impedance. The output impedance isn't zero, so you don't get a perfect voltage source, but it is low. Just what the ratio of input impedance to output impedance actually is depends on the current gain of the transistor. The higher the gain the higher the ratio of input to output impedance. That gain will vary somewhat from one unit to another of the same type and will vary with temperature. Usually with a DC motor with brushes what you want to do is control the speed , which is reasonably proportional to the applied voltage. If the mechanical load increases while the applied voltage is kept constant, the current increases, and vice versa. That low output impedance of the CC amp is just what you need. Overall the performance isn't great, but can be quite adequate for lots of purposes. (If you need really good speed control you'd typically use a tachometer in a closed-loop system, though you can do a pretty good job by measuring the back-EMF from the motor, which tends to be very linear with speed). There are circuits where you might add some extra resistance in the emitter circuit of a CC amp but that moves the circuit farther away from being an ideal voltage source if the load is in series with the added resistor. If a CC amp is used as the final output stage of an amplifier with feedback, sometimes a small resistance is used to isolate capacitance that may be present with the load. Capacitance can cause a phase shift that can play havoc with the stability of the system and the resistor can mitigate the problem. This is common with audio power amplifiers. Both JFETs and MOSFETs can be used in "source follower" (common drain) circuits for extremely high input impedance. The difference between gate voltage and source voltage is not as well defined as with BJTs.

Yes, it varies. So what? There is no need to a resistor there

@@elewizard OK

There are several reasons. See this video ukposts.info/have/v-deo/hGCCppeKkKdp1as.htmlsi=gcBXkraxCiDBjlcK

Thanks for the point ❤️

@elewizard I have similar vice type and without filter the sound is not good. In order to avoid post processing my audio every time I use Sure MV7 with their software. Once you setup the filters the audio is good every time. My configuration for creating UKposts videos is: I use SurePlus Motiv for the microphone , then it goes into NVidia Broadcast as I apply some extra filters and background blur, and then it goes into OBS Studio. I don't use filters in OBS though it has plenty. Just to setup my scenes, screen. My first video had terrible audio when I used my Webcam microphone.

Very interesting, thank you for sharing

Certainly, it is my todo list 👍

Nope, this configuration is called "Common collector" the circuit is OK. There is a dedicated video about this circuit on the channel. Look for DC motor speed controller video on the channel for detailed information on this subject.

❤️❤️❤️❤️

Welcome abdulbari❤️

So nice of you ❤️

❤️❤️❤️❤️❤️

Yeah, this point is covered in another video of mine 👍👍

Maybe

@@elewizard its true. Not only for integration of small electronics into big machines, but you can add complexity to circuits simply by having an entire secondary circuit connected via transistor. I use them for all sorts of stuff, almost as much as I use diodes.

Thank you for sharing 👍❤️

Will try 👍 Thank you for suggestion

Yes, I didn't cover cap multiplier and also many other usages of transistors to keep video time reasonable

Will do

Use alltransistors.com to find suitable part number

Thank you so much for your feedback ❤️

Hi there, @Artamicro

Try improving your English, so you can use many high quality content ❤️ try it my friend, you can do it

Wow, thank you😃

Maybe

Yes

an advice: stop@@elewizard

It made me sad. Sorry for that❤️

try a more organic video. maybe it s less pauses that way... and show more!@@elewizard

I think less pauses means more idle time.

how is that? the less you pause the less you idle.@@elewizard

​@@elewizardI thought it was great and didnt have issues with your accent. Cheers mate

Thank you for your comment 👍 I think your opinion is right in most cases
