In 1975, I told my scout leader I was interested in Electronics, he gave me a 1974 Signetics Digital Linear MOS Data Data Book (One of the most beautiful Data books of it's time). I carried that book everywhere and taught myself digital electronics design. That Signetics Data Book was the start of a long career in electronics engineering . I'm now 60 and retired, but still have that Signetics data book in my library.

I was a Computer Engineering major in college. The thing I liked best about my EE classes was the total lack of memorization. It was all about developing certain ways of thinking about things and processes for analyzing them.

[@The.Kid.From.Daycare.]

Absolutely agree with this. I’m a civil engineer and feel the same way. I hated chemistry because of having to memorize things and names that were so similar (nitrate, nitrite, nitride, etc.).

[@VideosViraisVirais-dc7nx]

Certain ways of thinking... Interesting. Like when you know the π is just the division/ratio of the circle circumference by the radius.

[@VideosViraisVirais-dc7nx]

When I was learning trigonometry, I was struggling about memorizing the ration division, like when you wanna find the sin, but you don't remember if you have to divide the hipothenuse by the opposite or by the adjacent. I only managed to memorize after understanding that most of the rations are below 0. So it means that the hipothenuse is probably going to be the denominator(the number on the bottom of a fraction) or divider most of the times.

This video explains my outlook on life/learning very well. The older I have got the more I have realized you can learn anything just by putting your genuine attention and curiosity into it. You said "you don't worry about the stuff until you need it then become an expert on it". I learned programming as a high schooler just from wanting to create stuff and I became good enough at it to secure a full time job in it. 3 years ago I purchased a corvette and now I am a pretty great mechanic just out of interest and necessity. You just have to go into stuff with the mindset of "I can do this" and you'll get there. I'm painting my car next week lol I've never painted a car before and most people will tell me that it's gonna turn out bad if I don't spend $5000 but you just gotta not listen to that and go for it. I'll just keep this outlook for the rest of my life because I love the freedom it gives me

[@michaelmoorrees3585]

I have an EE degree, and what you learn in school, is mostly theory, on how circuits work. Very little is taught on circuit design itself. Some in digital electronics, but less in analog circuitry. Most of what I learned is self taught. As far a math goes, in engineering school, they do go into the derivations. But what's really important, is the concepts behind the math. Knowing the math concepts can often help you design a simpler circuit. For example, the "sampling theory", which is the SAME as side band modulation, mathematically. Lots of harmonics generated, but if generate a perfect square wave (exact 50% duty cycle), you'll see that all the even harmonics disappear. Only odd harmonics. One of my old bosses, used this to create a simple tape erase system, that REQUIRED a sine wave. He just used a simple flip-flop stage, that made a perfect 50% square wave, that he fed directly in the erase head, as the inductor, and a cap so it would resonate roughly near the square wave. That combine provided enough filtering to get a perfect sinewave, because the 3rd harmonic amplitude was small enough to not be worried about. The competition, used an overly complex multistage multiorder op-amp filter. Both worked the same, but our was cheaper and more reliable.

I think this is brilliant. I learned electronic circuits in the early 90’s on a polytechnical school. At the end I received a diploma and was able to calculate voltage dividers, coil hysterisys curves, ntsc and pal vectors… but I had no clou how to build things. Because we had not learned how to bring this in practise. We had no youtube back then. Just our teachers who learned their ways to us the way they had learned it from their teachers. After a few years I quit my repairjob (Most of the time I had no idea how to repair. Just switched components until I had the right component removed and replaced) and went into computersciences. That was the end of my electronics ambition. Now, after almost 30 years, I reenter the world of electronics because I’m missing the one thing in my life that really has my interest. Electronics. But instead of learning all the equations, I bought a multimeter, a power supply, an oscilloscope and a function generator and some components and started playing. Blew up a lot of things (my first led went with a real ‘bang’) and learned by doing. And I have the greatest time of my life. Sometimes I look up the math to start understanding how it is working and it all falls into place now. In stead of trying to memorizing the math, it now is more like understanding the situation and applying the math out of it. I think this video deserves way more likes and views and should be an inspiration to everyone. Thank you sir!

Mr electronics, respected dude, I am now 60 years old, and have done electronics since I was about 7 years old. (Simple experiments with radio) Nothing in this life is actually learned unless you learn it yourself. I did not go to school for the last 2 years of secondary school. This is because I am dyslexic and they did not help me. This is a good thing because it taught me how to teach myself.

It's a great starting point however, so keep doing and learning. Also, some mathematic background REALLY helps on the hard stuff, the stuff where there is a lot of money to be made, so don't neglect formal education if it's available to you, even something as seemingly useless as Maxwell equations are almost mandatory to understand when doing high frequency design (microprocessors and DDR3 RAM interfaces on the 1-2ghz frequency range).

Instead, act, and let that lead you to inspiration.

[@davidjh7]

I totally agree that getting that gut feel for a circuit makes all the difference. I've been in love with circuits my whole life---I'm 61 and still get excited by a new circuit. One thing I have found useful in understanding a circuit, is to look at the limiting cases, and the mid-line case. So, for the filters of this example. The limiting case would be opening up the capacitor (low frequencies) or shorting the capacitor (high frequencies.) Midline would be where the frequencies start rolling off, or the 3 db point. That is where the gain is half, so the value where the capacitive reactance equals the parallel (or series) resistor. I have found this can give a real insight, for me anyway, on the circuits operation, or where it can go off.

[@RideGasGas]

Thanks for this video! Likewise I had a non-traditional path to becoming an engineer. Got interested in electronics in high school while playing with CB radio in the mid 70s and then discovered ham radio but didn't know any hams to get started. I did buy the ARRL handbook - 1977 edition - and started learning from that which gave me a jump start on later studies. Joined the Army in 1976 to get my college paid for and went through the Army satcom school to become a 26Y - satellite communications ground station equipment repairman. It was a year long school that took you from introductory basic electronics all the way to microwave and satellite communications concepts, and included also included repair of cryogenically cooled low noise amplifiers, heat exchangers for liquid cooled power amplifiers, and air conditioners. Took additional studies while in the service including a communications engineering correspondence course and some college math classes. Had every intent of going on to college after leaving the Army but the experience in satcom from the Army actually landed me a nice position with a commercial satellite communications company right out of the service. Hired on as a field engineer and was promoted to a junior engineer and then started moving through the ranks. Had many great mentors along the way and supplemented that with a lot of self studies and a class here and there. Eventually someone suggested I look into getting licensed as a Professional Engineer and I did some additional studying to do that. Thankfully I had participated in an apprentice program while in the service and had logs for all my experience, and that plus transcripts of other studies were enough to satisfy the board that I had met the equivalence of an ABET accredited engineering degree program and I was able to take and pass the EIT exam and then later the P.E. electrical engineer exam and become licensed. So, for anyone interested in learning electronics - if you're here watching IMSAI Guy it's a good guess you are - then I totally second picking up a copy of the ARRL Handbook and some other great publications that they have like the ARRL Antenna book, and digging in. Get a starter kit and just start playing around. Turns out the sky isn't the limit - you could communicate to satellites or beyond to another planet ;-)

[@spartan456]

I've been repairing electronics professionally for the last 10 years or so. It all started back when I was 6 or 7 years old, my dad picked me up an "electronics learning lab" kit from Radioshack. I'm pretty sure I still have that thing in a box somewhere. The kit was amazing! It was a big rectangle with all these knobs, switches, lights, connectors and meters, with a breadboard slapped in the middle. The kit came with a huge assortment of components and three books. Two of them were lab books (containing exercises to perform on the kit), and one was a book on how to actually read and interpret schematics. My dad and I would spend HOURS assembling different circuits out of those books. To this day, the _only_ reason I know how to even read schematics and make sense of them is because of what I learned in those books. I may not know the equations and the math for how a lot of that stuff works, but when it comes to repairing electronics, you don't need to know _why_ the designers specifically chose a 200uF 12v polymer capacitor to place in that particular spot of the circuit, you just need to have an idea of _what_ that circuit does, and what purpose that capacitor serves. Is it filtering? Is it decoupling? Is this particular circuit supposed to produce a necessary voltage to make something else in the device work? Is it maybe not working because this capacitor has a fault? Repair in specific is one of the coolest aspects of electronics work in my opinion. It combines so many different fields of work into one. PACE put out some amazing videos on rework and repair back in the 80's, and they described repairing electronics as being your very own process engineer. You have to find the fault, fix the problem, and restore the circuit back to as good as or equal to manufacturer specifications. You have to do all of this maybe without even knowing _exactly_ how the circuit works or the math and equations involved. I for example don't know the exact math behind the principles of a resonating circuit, or the exact breakdown of how PWM works, but I know what a boost and buck converter look like. I know _what_ they are supposed to do and roughly how they do it. I may not know _how_ filtering works and what that does to apparent and real power, and what the current over voltage waveform would look like, but I know that if one filtering cap out of a dozen is shorted, it's going to screw the whole rail and that voltage won't go where it's supposed to go.

[@davenordquist4663]

I mean, microelectronics have negative capacitance available now and every month brings more magnonic and memristive components; serial ports can deliver 200 W safely. Fire up Wolfram and see if it helps decide whether to throw a stonking ultracap in here or there. There's some decisions to be made to bring circuits to polity outside the context of just picking the right family of FPGA and IDE.

I've still got a 300watt mosfet amp that I made in 1989 that I gigged with for years and it still works.

I draw parallel to software engineering where it’s nearly impossible to know/think/comprehend the whole software and hardware stack, and it’s not strictly necessary. You make some assumptions, simplifications and optimistically move along. However, it’s good to recheck your assumptions and how things might go wrong if you want to have something robust and not just proof of concept. Learn by doing but also spend time reading to bring yourself to the next level. Some high level ideas require thinking and not just experimenting. Just my 2 cents.

[@jeffallen3598]

For me, i got into this like i did with programming… I had a need.. Not job related or anything, but something at home i needed to fix and something i needed for various uses. Once you have that personal need, you will be more interested in seeing it through. Most people that have issues are just learning because of a job want or just curious. So for those people, all they can do are tutorials. Nice, but easy to give up when things get a little tough. So have a need that you can use in your daily life.. For me that was fixing kids toys and eventually enhancing them. You don’t need to start out building things from scratch. Just like programming where you can just download some code that will serve a function for you and then modify it to your likening or purpose.. You can use something simply thats not working and try to fix it. Usually kids toys fit that bill well. And make some kid happy at the same time .. Learn how different tweaks give you different results. For me, that process really sped things up and over tine you may encounter more complicated things that require more study. But that wont be so hard since now, you have a successful background going for you to build from and not start out cold turkey…. The key take away is to work on something you need, to learn from as it make the learning process more interesting and less likely for you to quit if things get a little tough. Also, when i was ready to start more advanced things… I started looking at power supplies. Anything that does AC to DC.. They are everywhere and will teach you A LOT.

My interest in electronics began when I was no bigger than I could fit in the small cabinet under our fridge. It was cozy to close the door but it was dark. A flashlight first solved the problem. Then I wanted a permanent installation so I mounted a battery, a switch and a lamp on one wall.... When I started school and learned to read, my visits to the city library began but there were very few books on the subject. Fortunately, English was/is compulsory in the Swedish school early on. And pretty soon I could start buying electronics magazines in English. Both British and American. In these magazines there were ads for electronics books and I started ordering from the US. And I really want to say thank you to all the educational authors in the USA who produced very nice books on the subject!

Thank you for your videos.

[@itsevilbert]

Everything complex, is just made up of lots and lots and lots of simple things. I like to understand all the simple things, that way nothing scares me. If you wanted to design a 64-bit CPU from scratch, the best place to start is probably with a 2-bit CPU - totally useless as a computer, but one hell of a good place to start learning. Even just thinking about all the things you can not do with only 2-bits will help you learn.

[@foodgeek.]

As a newcomer into electronics, I've found this video right on point. Getting hands dirty naïvely and then learning how/why you've seen such result is pretty much how we learn in life. Kudos to you for such a good channel. Just make sure you are in a safe sandbox and nothing will blow up if you mess things up😂.

[@diremaykr4855]

I had a similar experience in circuits class in university. I was struggling with the math on tests and having trouble completing them on time. By the final I started thinking about it in terms of what effects the components would have in circuit rather than doing all the math first. That gave me a close idea of the answer, and then afterwards I would go back to verify with math if time was available. Ended up with an A on the final :^)

[@diremaykr4855]

@Thawne It's hard for sure. I went to university for a bachelors and got my job in the final semester. I think employers want to see a mix of education + practice (projects, experience, etc). I didn't have much experience outside of university at the time and think I got a bit lucky there. Maybe you can find like-minded people in your local area (interested in electronics or another passion). That would help keep you interested because there's peer pressure to continue participating.

Hey man thanks! I think the video has the exact amount of humbling knowledge you need to start a journey onto learning the unknown. It gave me guidance.

[@mstover2809]

While my father helped get me started with the basics, I learned MOST of what I know much the same way as you - my first book was the handbook written by Bill Orr, W6SAI followed weeks later by the 1977 ARRL Handbook. Loved the Forrest Mims series of books sold by Radio Shack too!

[@BoxingDayAC]

BSEE here. Great video and I like that you show an actual book to learn from. Let me comment on phase. Most of the time you're right, it's not important / can ignore. Where it matters: a) Non-linear phase change is distortion and too much distortion changes the frequency response. This is because phase modulation and frequency modulation are two forms of the same thing. The group delay is another metric. Smaller is better. Total harmonic distortion that an oscilloscope gives you can be a helpful objective measurement of said distortion, along with SNR. b) Analog to digital conversion (ADC) because the sampling occurs on a specified phase and the phase change, such as from a filter, changes the optimal sampling phase. Can either change the sampling phase or add an all-pass filter to cancel out most of the phase change.

I agree so much with your comment 'learn it when you need it'. It is often far better to have some broad knowledge in an area with a high capacity to self-teach, then to be super expert in one thing with no desire to learn something else. Certainly their are jobs for the super expert but there are far more jobs for the individual who can learn new things as needed.

Your advice for people wanting to learn electronics is great. It is exactly how many of us have learned. Myself included. I have three grown children. Oldest a Mechanical engineer, a daughter who is a speech pathologist, and my younger son has a degree in physics. Carl the youngest is working as an electrical engineer, and he bootstrapped himself in exactly the way you describe. It takes curiosity, and being tolerant with yourself. Everyone feels stupid on occasion - everyone. That will happen as you investigate - and that makes the breakthrough events much more sweet.

I bought almost all the Forrest Mims books at Radio Shack as a little kid in the late 80s. :) I didn’t fully understand them at that age (8-11ish), but still, they helped spark my interest.

[@MrLsouza77]

My passion for electronics dates back to 1986. But it took almost 40 years for me to understand why I had made little progress in the field. Firstly, a tantrum with digital electronics, which still costs me dearly. I am considered an intelligent person, but in order for me to learn, I need to know exactly what I am learning. I can't learn something if I don't deeply understand how it happens. Not because of a lack of cognition, but because of a lack of attention. I'm currently struggling to finish my bachelor's degree in Electrical Engineering, and when I realize that the course material skips a single step or is a summary of a book by a great author, like Ogata or Nise, I freeze and review everything until I find the missing piece. . This makes things very slow to achieve. This is called ADHD.

[@Noconstitutionfordemocrats1]

Yep, I've changed my attitude on learning a lot since I started teaching myself programming, electronics, and engineering. Physics teaches you how to approach a topic very rigorously from the ground up, and that's great for pure theory, but not so great when it comes to practical applications and just making a thing do a thing.

[@isettech]

I started young with electronics as a kid. First formal training was in the US Navy in the advanced electronics program. Challanged the Beginning section after they handed out the DC fundementals textbook. I tested out and went to ET A school, where I did learn to do series capacitors and parallel resistors, Maxwell's equasions, RC time constants, etc. After that went to my C school for my specialty where I learned the finer points of RF and Tempest. After the service learned VCR's (new at the time) Laserdisks, CD's, and tube projection television. From there learned two way trunked radio, paging systems (old school beepers), marine electronics, PC's, etc. Had a career in semiconductor manufacturing in Research and Development. On the side learned event sound and lighting. Yes, play with the light programming for concerts. Moral of the story, in electronics, you never stop learning as there is something new every day. Just bought my Midas digital console to learn and use. Day job is in robotics and motion control for photo-lithography for semiconductor manufacturing. I now have a good handle on tuning a PID control for motion control.

Learn by doing. Many years ago, when I lost my job, I got a chance to take a class in analog and digital electronics. It led me to understand the connection between mechanics and electronics via various sensors and such. Back in those days, Sweden was a rich country that had money set aside to help people who showed interest in learning new skills to improve their chances on the job market. The education was based on "learn-by-doing", learning how to use various tools to measure and find errors in basic circuits. This KZbin video brings me back to how I got my introduction into the world of electronics, something I've had great use for when I got into build-in systems and IoT. 👍

[@fretronicsengineering]

This is great, I run an audio electronics company (company account) and I went to university went through and have got a Masters degree in EE. We do design and repair for the audio world. The funny thing is, I came out with a 2:1 (second class degree), most of my colleagues/friends got 1st class degrees. They were all better at exams - any project or practical design work and actually DOING electronics, I was miles ahead despite on paper being not as smart. Actually building stuff and having fun is how I learned what to do and not to do. The maths helps - but the maths is a means to an end whereas its taught largely as the end goal itself - hence why they did better in exams but in the real world I am far excelling. Electronics is as much a creative art as it is the physics behind it, you need to have a creative brain to design and repair and understand how everything works in reality - algebra is great until you don't understand why it doesn't work in real life! Great video, will subscribe.

[@gabrieleproietti8802]

You've said some incredibly big and true things my friend. 99% of times in engineering universities we are used to study from global cases to corner cases, never going into easier but more pragmatic stuff. Knowing well how things theoretically work is waaay distant from barely knowing how to make them work. P.S. yep phase is used to understand stability of sistem, from Nyquist plot phase is useful to understand whether system is in critical stability condition or not (everything can be determined with proximity to -1,0 critical point), but considering that EVERY product in mass market has already been pretreated and stabilized, it's quite difficult to pragmatically recreate corner cases that are taught at uni. Have a nice one!

This video has inspired me to get back into electronics. I was first interested as a kid/teen by studying PCB designs in my home computer and was fascinated in how everything was arranged and how it all worked. There werent any women I knew into those things so it was just my cousin and I taking apart every computer and radio in his house together ( much to the dismay of his parents). The same interest followed me into the Navy as an ET. Your comment about the math resonated with me as it was the math that sort of shied me away, but getting out there and doing, getting your hands dirty, and not being afraid to fry a couple cheap bits is really how you learn. The doing also helps you to then understand the theory. Im getting back into this at 32 as a hobby hoping to one day be able to design my own PCBs. Great video and advice.

My best professors when I was studying Finance as an undergraduate were the ones that spent a lecture or two going over the math and theory but spent the rest of the semester showing us how to use modern tools (excel, etc) to handle the math so we could focus on real-world application. This was a much better approach for preparing for a career.

Not as complex as it seems. That particular book (which has a 2022 version) and some others include basic circuit explanation. In my opinion a nice-to-have would be for a book to include a typical component connection example (i.e. in this case say a 741 and include the power connections) and then example input and output scope traces and voltages, something I miss from my early days working in TV and radio. I know some books include such 'additional information' but there is nothing worse than having to refer to multiple sources of information to connect and understand a basic function.

We live in a world where not attending university and obtaining degrees labels self-taught individuals as uneducated, while in reality, degrees and titles make you a puppet in the hands of corporations. Thinking cannot be taught at universities, as they are not there for you to think. Likewise, practical knowledge is conveyed in very limited quantities at universities. If you want to be an independent thinker and are not interested in indoctrination papers, the only way out is to find a passion and educate yourself. An example is Heaviside, who improved Maxwell's equations. He was hated by the scientific community because he achieved everything on his own, and it offended them that an uneducated person was capable of independent thought. Nothing is more fascinating than self-learning. Keep it up.

I too am self-taught at electronics. I am pretty early in my self-taught education at the age of 29 (started about 2 years ago). Its a lot of fun and I’m really glad that I went down the self-taught route instead of waiting for colleges to accept me for the stupid degree. Regarding your point about feeling vulnerable about admitting that you’re self taught: I also have that vulnerability. I think most self-taught people do. From my experience, some people are assholes who go “how can you be self-taught in electronics? you have to go to school to learn anything!”. I find that funny because 1) The fact that a person feels the need to go to school to learn something shows how little self-discipline and lack of self-assertiveness they have over their lives. 2) at the end of the day, knowledge is knowledge.

Excellent. I find that I need to actively coach myself. To intentionally take on the role of active-learner. Apply basic learning 'tricks.' 1. "Do" is a good first trick. 2. "Be suspicious of one's memory/understanding" - Immediately apply any new information. Repeatedly. 3. "Try to guess ahead" when leaning something - it wakes up all sorts of unconscious/dormant knowledge. 4. "When curiosity flickers, immediately feed it and fan the flames even irrationally" - curiosity if the creature you are trying to tease out of hiding. Our conscious attention grossly overestimates its own abilities to understand, remember, recall. It thinks it is totally in control. It is not. Learning this and how to apply ones conscious attention in the moment might be the ultimate trick. I think many people assume you can sit back and mostly be "taught".

Regarding the phase change and whether or not you need to worry about it... *this* is a critical skill that's often overlooked in traditional study. You *need* to learn to identify the "don't care" stuff so you can throw it out of your brain (and your solution) as early as possible. This honestly requires a *genuine* understanding of the goal/product, something that a lot of people don't have when they're only working on one little tiny piece of it. Before commencing any work on your segment of the product, you would be well-served to step back a bit and develop a true understanding of where your piece fits into the greater whole.

Hi, thank you for making this video. Actually, I have a math degree (graduated a few years ago and theres a long story behind that). Very similar to your childhood story, I’ve always been interested in opening things up (especially electronics) and I really enjoy learning about electronics. I’ve been (really slowly) self-learning electronics in my free time. I like to spend my time really trying to understand the material (typically it leaves out explanations for why things are the way that they are). One thing in my learning that I need to do more is do more hands on stuff like you’re suggesting and just to try out stuff, even if it means it breaks. I know that this field is extremely protected, meaning that some people who studied electrical engineering formally will say nasty things towards you if you share that you’re self-taught in electronics. Sadly, this has been my experience. I’ve been bullied by electrical engineers basically. My day job is embedded software engineering (again, I have a math degree so im all self-taught). The amount of hate I’ve received for being self-taught is ridiculous. But, this is my path in life so I’m going continue to pursue it, even if other people have issue with it.
