26 years old, starting my electronics journey and I can already tell you're a great teacher. please keep this series going
50y old....continuing where i stopped in elementary school. 🤓
@@ItsGoodToBeHaterI’m 66 and now have all the time to learn this subject which I always had an interest in. You’re never too old to learn😊
Great work, Leo. Self-taught in electronics, I was put off by the math. 27 years later, I'm teaching my students with a similar intuitive approach first and will definitely point them toward your video series. You're a great explainer. Respect and thanks from Waterloo, Ontario Canada.
I have never been one who intuitively understood mathematics, it has always been very foreign to me. So, years ago, I struggled greatly with it. Then one day while in a used book store I found a copy of Mathematics For Electronics, by Clyde N. Herrick. This author assumes that the reader does not have any previous training in math and he takes you one step at a time through it. I have learned a great deal from this book and it is an invaluable resource for me. He puts all those authors out there writing math books to shame, as the vast majority of them assume all you are wanting is a refresher course. I would suggest to everyone interested in learning electronics to do everything they can to locate and buy a copy of this book. They won't regret it.
BRAVO!! You sir, are an awesome teacher!
I am 51 years old, and I Thank you for your Awesome Program that I thought I could never learn. GOD BLESS YOU
Great job. I really hope this series gets the audience it deserves. Your explanations bring real clarity. Thanks.
This is so kool!!! LoL when I first heard you I thought “Oh No” what is this guy selling. Then I said to myself, calm down and listen to what he says on a lesson.
I love the concept you are using to get us started.
I’m 75 and retired, I had my own business for almost 60yrs mostly creating things for people on furniture or in their homes plus add some music in along the way.
So now I decided I’m not throwing one more tool, appliance or gadget away that looks brand new unless I try and fix it. I’ve purchased the basic tools and already fixed a few things😊
Next phase please, lol, electronics.
Is there someway we can support you here?
Thank you very much!!!
Very intuitive and easy to understand in laymans terms. 👍
This is explained so explicitly and well, thank you for your work
From Tunisia, Good work. I m also electronician and appreciate your mode of explanation. Thanks
❤exactly the type of guidance I was seeking for .
I just found your youtube channel and am totally blow away by your knowledge and teaching skills. I have a Masters Degree in Science of Teaching and can say you have mad skills. I also watched one of your other videos where you say you are a high school drop out. Yet I see a person with a comprehension of electronics that some formal educated people do not have. I can only imagine what knowledge you would have and the contributions you could make if you had a PhD in electrical Engineering. You also would have made a top notch teacher for high school or an adjunct professor at a University. I especially liked the part where you said you learned the hard way by keeping your nose to the grind stone and not quitting. My education is in the sciences, chemistry, biology and mechanical engineering. I am now 66 years old and retired and have been learning electronics over the last three years just as you did by teaching myself, trial and error, reading and doing and keeping my nose to the grind stone. I now have gotten to the level where I have a small shop in my basement and repair radio receivers, stereos and other home electronic devices as a hobby. Thank you for your efforts to teach and I subscribed and will be watching all of your content.
Thanks- very much appreciated.
I love the analogies and the simplicity you bring to these concepts. I am currently learning electronics from University and I am here to say that I would have caught on so much faster if the fundamentals were explained this way. I remember when I was first learning about voltage and current from school having such a difficult time understanding what was actually going on. If I watched this during my first semester I would have saved myself tons of headache for my future classes.
Love your channel . Plz continue the fun electronics project series
Leo, Happy New Year mate, loving the work you are doing and the end result, will be mind blowing, I’ll be sure to watch the whole series, keep up the amazing job. 🤙🏼🇦🇺
Simply explained. For many students, this is often a difficult subject to grasp. The relationship between voltage and current is not easy to explain, but you managed it expertly. We are hoping that you will continue this course into semiconductors and beyond.
👍 Looking forward to future episodes, Leo. Thanks for making this series.
Looking forward to more!
Excellent video, possibly the best one on the topic! Though I know this stuff for ages, it was a true pleasure to listen to you, Leo!
Great video Leo, absolutely loved your straightforward and intuitive approach to explaining the fundamentals and can't wait for the rest of the series!
Thank you, Leo! I look forward to the rest of the series.
Being a student with major in electronics i can say you have quiet an extraordinary way of explaining concepts. Well Thank you and keep the good work going.
I'm so excited to the next video 😌😌, I hope this series go even to 100# videos...🤓🤓
Looking forward to the rest! Great style.
Looking forward to this series
Great illustrations. Keep it up!
Excellent video, Leo. Please keep them coming. Thank you very much!
First off, Great Shirts! Secondly, lessons seem really accessible, and I can't wait to move on.
I like your approach. I was never great at math. My Father could do high math like a musician sight reads music. His brother was a human spreadsheet- he could add long strings of figures in his head. Some how it missed me. The conceptual approach I think works quite well.
Really good. Thanks.
Excellent! Crystal Clear! LUCID!
I’m 52, and have never been exposed to electronics. But I’m very interested in learning! I’m horrible at math and one other video started right into it and I freaked out and left. Since then I’ve bought a kids snap circuit kit to hopefully help me understand but I’m finding myself upset that they show you project but not offer the whys in how it works. I found your videos and I hope that I can catch on and not get overwhelmed by the math of it. Looking forward to the next video!
Great work again Leo. I always wonted to learn electronics sign up to many online courses just to be lost on mathematics. I hope you will continue this series . Thank you for dedicating your valuable time to make this video.
Subbed!! You're what I've been looking for to help teach me this vast world of electronics. Thank you for taking the time to help us in our hunt for knowledge!
Great to see you back Leo!
Thanks Leo I'm looking forward to following you're lessons.
Another great video again wow very educational 👍 🙏
Eureka! What a great video to learn electronics. Your visual aids and diagrams along with your clear cut explanations made for an easy to understand lesson.
Very interesting. Im retired and trying to learn some electronics but like others put off by the maths.
Thank you for bringing 'soft stuff'like inspiration, joy and intuition into this 👍🏼
Bravo! Love your teaching plan and method. Wish you every success.
You make beautiful tutorials!! Thank you so much !
I am really happy that you are making this great quality content! Thank you so much!
Yes mate love the way this is going, looking forward to the next episodes 👍
Thanks for the effort you've put in making this video. I specially like the way you explain abstract ideas using simple analogies. Hope this video gets watched by as many people as possible. Cheers,
very good, please keep going
Great video, I'm excited to see the next few lessons, I just graduated high school, and I wish I had learned more about electronics sooner. Thank you!
I can definitely relate. Too many instructional materials focus on the math instead of concepts. Instead of explaining relationships using real world analogies, many of them jump right into equations and graphs. It's not so much that the math is difficult, often it's just basic algebra. What makes makes it difficult and discouraging is seeing the relationships in the math. Electricity is analogous to hydraulics and pneumatics, yet both are far more intuitive because we all have observed their behaviors and properties in the real world.
I’ve watched many videos, including those on Udemy. You are the first person I discovered who could clearly describe the electromotive force to me. I will watch your series. I love electronics and can solder and replace capacitors but I don’t enough of the basics and how to troubleshoot faulty device using a multimeter. I should probably by a book as well. Thank you for putting this video and hopefully others. I subscribed.
This is great! Definitely looking forward to more, thanks :)
fabulous !!
Really nice, even as someone who already knows about it, I never really use it so a refresher is always appreciated.
I love this video . The simple and clear way you present the principles is fantastic . I am looking forward to this series . You have a love for plants like my mom did . When I was growing up I would say I heard jungle drums last night . She had over 300 plants in the house . She had a green thumb . Thanks for sharing , stay safe .
Terry
Thank you for the video and the series. My son is just discovering electronics and will find this really helpful. We'll stay tuned.
Amazing effort, keep the good work! Thank you, Leo!
You're an excellent teacher, bro! I love the simplicity of your explanations! Keep up the good work! One more subscriber here!
Voltage divider circuits would be a good mention because I used one once in a low-current situation to take the magneto output of an engine and divide it down to 5V level. Notice I said low current though, just for signaling, so I didn’t need to use high power resistors. Your video here really demonstrates why! ❤
Good job on ease and presentation hope you will make a playlist for beginners. Thank you
More people would go into electronics if it was taught this way.
Appreciate you Leo!
Please keep these coming.
Man i just found your videos and there were really helpful. Keep it up, it looks like you have a ton more of experience than me.
In solid copper (and other metals), the electrons are actually unbound. More precisely, the electrons are strongly bound to the extended solid, but they are NOT bound to any particular atom. This is why they are great electrical conductors, why they are great thermal conductors, why they bend easily without breaking, why their heat capacity has no aT term, etc. Each conduction electron is 'delocalized;' each wave function occupies the entire object. There is no way to identify any particular electron because they are all exactly the same. To predict what we actually observe, it is necessary to expect that they spontaneously exchange states in pairs at short, random time intervals.
The balls' friction only interacts at the surface of the tube; however, resistance occurs throughout the object's volume. Each electron collects kinetic energy (velocity) from the applied electric field and interactions between the electrons and the 'stationary' atom cores causes these cores' shaking to increase; "phonons" remove energy packets from the electrons' movement and deliver it to the atoms.
Great video thanks i will definitely watch the rest of the series 👍😁
Please continue with this series
Thank you :) Great job
This is awesome! I’ve always wanted to learn electronics but there is so much overwhelming information
this is very informational
I ll stay tune for sure abd thank à lot for ur vid
Yahoo! Thank you for this.
Please continue the series
I really really really want to become a small electronics technician but i just don't know how to go about it and everything in the video makes me want to do it even more if you have any idea where to start please let me know this is something i want to do for the rest of my life and i loved what you taught me in the video i appreciate all the info. Thank you!
I like the physical analogous of wire.
Much obliged.
Wish I found your channel sooner…. Subscribed …thanks Leo
Just whay I needed !!
I have a PhD in science and have been working as an engineer for multiple years and I can say your lecture on this topic is excellent. Thank you for sharing your knowledge with us. By the way, I love the random appearance of shirtless guys at @4:18.
I’ve been liking brushing up on electronics, the Leo’s Bag of Tricks Way 💜
Please 🙏 continue this series please
You are a great teacher. Good luck with your channel. I have subscribed.
much appreciated
This is Wonderful! I AM your target audience and I am so grateful for your work... Thank you.
In copper wire, there are free electrons that flow randomly, from atom to atom. Only when an external voltage source is applied, do we get the flow of electrons, which we call current!
Great idea to build knowledge in a layered approach with the clarity you always convey! Wish I had access to such a series when I was starting out.
Just one point - in the battery cutaway diagram at 3:55 aren't the cathode and anode incorrectly labelled?
Electronic components (silicon, germanium) schematic diagrams use conventional current for the arrows (P to N direction) seen on all of the accepted/standard symbols. It's far easier to explain the diagram with the conventional current as Leo points out. I am an older electronics tech who has worked on complete avionics systems with both transistors and valves across comms and navigation devices.
YEEEAAASSSS! MORE EDUCATION!
lovely! leo, I wish this would be availlable in german too...to show it to the kids here
I know that these take quite a bit of time to make, but it would be nice if they were much longer.
Great job.
I understand your aims; but I'm not really a big fan of the triangle for remembering formulae. I have had so many students misremember the triangles they were taught at school, when a little bit of simple algebra is all that is required.
Other than my pet peeve, you are doing a great job - looking forward to seeing more!
Point is somebody called negative electron negative is because that electron is full of electron for pretrculy material, so there is no movement inside of atom. When atom which has les atoms (called positive) is added near to atom with full of electrons positive atom will pull- attract electron of negative- full charged atom. That is how to explay that. Not going around and newer really explay to people how that really works !

I'm 60. My bro gave me a drone kit for xmas last year and I have been doing some soldering etc. It's interesting to learn. What if you have 2 resistors in a circuit? Do you add that resistance together? I'm totally noob..
Leo, can you help me look at a circuit and then draw them as a schematic by hand, not using any software? I would like a guide to reverse engineering at its basics. I've been doing electronics for more than 5 years but converting circuits to schematics is my weak point
What are the circles that show up at 0:30 ?
It looks like circular farming fields but I doubt that's what they are. Is it 3D beamforming with speakers/microphones or some actual circular antennas?
it wasnt ben franklins fault. who makes the fundamental unit of any system a negative. physicist already figured out how to deal with it properly by using the "electron volt" unit which is positive
3:08 Nice man
Great tutor 🙏 Do we gonna watch existential crisis video😂?
Where did you record this video? Was it somewhere in South Asia or Sri Lanka?
Hey Mr. DJ 4:18
I noticed you didn't directly connect "electromotive force" to "voltage" that I thought you might have at the ~midpoint of the video, and thereafter did not give a clear definition of voltage before using it.
