I've had a basic understanding of what a transistor does for a decade and a half. But it was seemingly impossible for me to ever use them in practice, mostly because I would not know which specific one to use for my ideas, but also because of all the obscure little details like pulldown resistors, bias voltages, etc. Having a guide like this that actually shows you how a general purpose transistor can be used in a variety of ways is gold! It's really easy to follow along when the unknowns are already figured out for you!

5th birthday i got a 101 transistor experimenters kit. When i finally understood how a transistor switches electricity without moving parts, i was totally hooked and became a self taught electrical engineer two decades later. Clept out of most classes for my degree. You can be anything you want if you are dedicated and fully interested in what you love to do. Find what you love and you'll never work a day in your life because it wont feel like work! Inspire someone now and genius will follow.

Watched the whole thing. Really love that you did this. I hope you keep doing more like this. :) Back in the early days of my career, because I was taught “how” relays worked, and not just “follow the instructions”, I was able to design my own latching relay with multiple bosch 5 leg 12v automotive relays, and I was so psyched that I could, then make all kinds of circuits in car audio. I, recently worked with Cheng Lin from CLRacing to create a product for car video screens in Polaris Slingshot vehicles, for multiple camera views, based on left, right blinker or reverse. Basically, the car had 4 cameras and it would choose the camera based on the status of the signal lights. Pretty easy circuit to design, but, it was cool to see it come to life.

I resonate with every comment here. You re-defined how the knowledge is meant to be passed on and reminded people that math is a representation of observations and can never be equal to the observation itself. This demo fired more neurons in my brain about the use of transistor than all of my 4 year undergrad syllabus did! Thanks a ton for putting actually useful stuff in here, instead of all mumbo jumbo. Hope to see more such useful stuff! I wanted to share my thoughts as they I passed between my ears. 11:47 actually nothing is happening - because there is an invisible barrier to lift the right transistor from ground to positive voltage, whereas the first transistor is in a more stable configuration with it's carriers having already crossed the depletion region. 12:40 when you add a RC circuit, it helps push the first transistor out of it's stable state by increasing the current flowing into the first transistor which triggers a voltage drop at the second transistor there by reducing the barrier to turn it off. If you added voltmeters at each of the nodes, these change would become more evident and we can see that the circuit is in a stable configuration even with a loop when RC circuit was not added.

Thank you for your channel. Here is my story. I started my apprenticeship back in the early 1970s and initially worked on relay logic ccts that included mechanical rotary selector switches that were also used in telephone exchanges and various relays, relay logic and control systems. I also worked on plant (still in service at that time that was installed around 1918, but that’s another story 😂) I was then involved in the project of changing the control network over to predominantly TTL which involved hu feed of control cubicles at a central location and at remote locations, very few ICa and all this off hundreds of A0 size drawings. The design and control engineer committed his final act (ever) when we were about 79% done so I was moved to other work while the authority searched for a replacement. I moved on to a new employer and new field that didn’t directly involve electronics directly which required me to basically ditch electronics and learn new theory. Now retired for several years, I was recently reviewing some old notes I discovered and having once been thoroughly intrigued by solid state wizardry I’m now “roped in again” 😂. I found your channel and look forward to working through it to relearn long lost knowledge and skills as well as a few of the newer heeby jeeby bits. Oh, and I forgot, starting in the back end of the 60s, through to the start of the 80s I pirated ham radio, but all the equipment I had was valve, but again, that’s another story 😂. Thanks for posting my friend, if you lose me, better come find me. 😂 Cheers (73s) 👋👋👋

One tiny thing i would like to mention in case it helps someone. When showing the pinout of BJT NPN 2N2222, the camera flipped the proper arangement. If flatside is facing you with leads pointing towards ground, its CBE from left -right. Base is still the center but it got confusing when labelling ins and outs of inverter circuits.

To figure out which side is negative on your LED, use an old 3V lithium cell, it won't need a resistor, they have enough resistance internally (because they are old). So next time your kitchen scales say they are "flat", keep that cell. An old LED, cheap "surplus" LEDs or one taken from another board will not necessarily have a long and short lead, or a flat on the body, they could be either way round. I have some 1970s/80s LEDs that have a flat and equal leads but some are reverse polarity. Shorting out an LED is not the usual way to turn it off. Most people draw their circuit diagrams with the positive rail at the top and 0V at the bottom. It is not correct to call it ground, because it isn't actually grounded. A PC power supply might ground the zero volt rail, but a 5V "phone" power supply won't, and a battery wouldn't have either side connected to ground.

Nobody. (Ok, there are a few very smart physicists who have sophisticated mathematical models for how a BJT actually does what it does, but to everyone else, even all the electrical engineers that design really sophisticated circuits with them every day, it's still basically magic. (Knowing how to use them and knowing how they work are not actually the same thing...)) But they are, indeed, incredibly useful anyway.
