    This is fascinating. My brain always wants to know how things work completely, down to their most basic level. I still have a hard time wrapping my head around how you get from this simple logic to a modern computer program. It also blows my mind how fast it all happens. As I type this message there are thousands of electrical circuits and transistors doing thousands of cycles for every letter.

      What's difficult about binary? you only have 0 and 1.
      Then you have a few basic logic functions: AND, OR, NOT, XOR.
      Expand that to NAND and NOR where the behaviour is represented by truth tables. It's easy
      It gets a bit harder when thinking about the different types of flipflops.
      And a bit harder when it comes to finite state machines.

But even that's easier than having to actually fiddle with gates.

So many other tutorials leave a bunch of things unexplained which doesnt let the noob mind complete the concept. Thank you so much for making this! The simplicity of this is just remarkable and that this concept is the building blocks of making something like unreal engine has me feeling like yes, AGI is just around the corner.

    Hey, really great video as always. I got into CS a few months ago and this channel has been a godsend for learning about computer hardware components in a way that is intuitive and easy to follow along with. I read about logic gates and logic circuits a few weeks back, and one of the things that struck me was how apparently NOR & NAND gates are universal gates that can be used to construct all the other logic gates available. Perhaps for a future video, you could expand upon the stuff you talked about here by explaining how these more complicated gates work.

Yes, I would appreciate if you explained how to read or understand current vs voltage graph or hysteresis of capacity vs voltage or the physics of a single transistor(solid state memory) to the simplest circuit of transistors contains one transistor and capacitor. What's the difference between capacitors and transistors(their difference make up of the device). I am a chemist building the thin layer of a transistor and really want to understand beyond understanding the molecular make up of the thin film's chemistry or physics of it. Thank you so much!

    I remember testing a computer. We had a bezzel that held about 10 sheets of 15 x 20 with the schematic on it. We started on page 1 at the top left and pur a scope on every test point. If a part did not work we replaces the diod or transister. The system was sesigned by math people. They knew nothing about a pulse being delayed going through a transister. We had to add in circuits to get everything in sync. If somthing did not function properly, we had to sit down with them and figure out the solution. Those were the days. The kids today have no idea what really goes on inside a computer.

    I don't know how computers are designed yet but I have designed a calculator. To make design easy counting devices maybe are the way to go. For example, counter 1 counts up or down. Counters 2 and 3 only count down. The answer is always in counter 1. When adding the first number is loaded into counter 1 the second is loaded into counter 2. Counter 1 counts up while counter 2 counts down. When counter 2 equals zero the sum is found in counter 1. For the difference both counters count down. Again the answer is found in counter 1 when counter 2 equals zero. For multiplication the first number is loaded into counter 1. But when the times key is pressed the number is transferred into counter 2. When the times key is released counter 1 is cleared (reset to zero). The second number is loaded into counter 3. The number in counter 3 is the number of times counter 2 will count down to zero while counter 1 is increased. The reloading of counter 2 is not difficult but I am going to stick to the counting description for now. Each time counter 2 counts down to zero counter 3 is decreased by one. When counter 3 equals zero the product is found in counter 1. Lastly for division the first number is loaded into counter 1. When the divide key is pressed the number is transferred to counter 3. When the divide key is released counter 1 is reset to zero.The second number is loaded into counter 2. Counter 1 is then used to count the number of times counter 2 can be subtracted from counter 3. The quotient is found in counter 1when counter 2 can longer be subtracted from counter 3. Sequencers made of AND Gates Or Gates NOT Gates and Buffers are used to cause the counters to count as described above. Write me at Mark Finn P.O. Box 5038 Sonora Ca 95370 for all the information needed to learn calculators and video game design free of charge. But don't expect financial gain to avoid being disappointed. I am pretty sure money is not that way for most of us.
