Great video! This series has been so informative and helpful!

[@GlobalScienceNetwork]

Glad you found it helpful, thanks for watching!

I fell asleep and woke up to his enthusiastic commentary on the Oscillscope wave form LOL

[@GlobalScienceNetwork]

Ha ha nice!

[@trtl9106]

THIS IS INCREDIBLE!

[@GlobalScienceNetwork]

Ha ha exactly!

[@Enigma758]

Very nice design, the computer is coming along nicely and I look forward to your future videos. Would love to see a design for a transistor shift register/ring counter.

[@GlobalScienceNetwork]

Thank you! Yeah, it will be fun to see it all come together!

[@valovanonym]

I'm waiting for a gpt model made entirely out of breadboards, wires and breadboard components

[@GlobalScienceNetwork]

You are talking about a generative pre-trained transformer? Right now those run on digital logic which actually makes them very limited, (as in not ever going to be alive). We are going to be building off a much better framework, the human mind. We will start on breadboards but billions of neurons on breadboards is probably not a great idea.

[@valovanonym]

@@GlobalScienceNetwork I was actually kidding but yeah analogic artificial mind sounds cool. I'm looking forward to see what you will create

[@GlobalScienceNetwork]

@@valovanonym I figured and yeah it will be cool to see what WE create. Eventually, I will need lots of help.

[@SukiYaki1904]

Thx for the design, imma use it, I just made my first Full Adder with transistors using NOR gates.

[@GlobalScienceNetwork]

Sweet! It sounds like you are off to a great start!

Hello from EEVblog2!

[@GlobalScienceNetwork]

Cool, that is a good channel as well!

You made a calculator in the previous video, it was adding, can you make a calculator with subtraction?

[@GlobalScienceNetwork]

I might make a video showing this at some point. If you are interested in learning the method now you can look into a full subtractor. For the XOR and AND configuration, you can add two inverters to the full adder to make a full subtractor. The best way to make it so you can add and subtract is by inverting all the B inputs. So you have a 4-bit input A + inverted inputs B = A-B. This is the two's complement method.

I’m an aerospace student and I’m really interested in electronics what basics do aerospace engineers study that help them in electronics?

[@GlobalScienceNetwork]

At my school (Penn State) I was required to take an electrical engineering class. I took EE210 which was a 4-credit class with a lab. It was actually a weed-out course for electrical engineers so it was quite difficult. At the time I did not like electronics as much as I do now so I just learned what I needed to pass the class. Topics were mesh analysis, nodal analysis, op-amps, dependent current sources, independent current sources, etc. Building circuit projects on your own is more fun and a better way to learn electronics in my opinion.

[@moover123]

Great content. If you continue to work on your videos, I am sure your channel will grow

[@GlobalScienceNetwork]

Thanks for the positive feedback! I will be adding more videos so we shall see what happens.

[@tallmatch5866]

Hello my smart and talented friend! I have build all the components of the binary counter but I'm having a problem with the multivibrator. In your video when the diodes flicker one diode is completely off and the other is on, they swap their state in a nice constant way and the on/off periods are even.. On the other hand, despite showing stable constant flickering, the Reset diode most of the time is on while the Set diode most of the time is off. The Reset diode turns off for a very short period which I think is the period of the capacitor discharge, and then, it turns on instantly. I haven't assembled the binary counter yet, and I don't know whether such behaviour will cause problems. Will it? Thanks in advance. PS: Is there a community to which I could appeal next time to not distract you every time?

[@GlobalScienceNetwork]

Hi! Yeah, it is best if you can get a nice square wave with even on-off periods. My guess as to why your circuit is behaving this way is because the two capacitors have different values or you have resistors with different values. It is hard to say without seeing your circuit. You can always build the circuit the exact way it is in the video. You can look at the circuit and use the circuit diagram for the values. It is possible you have a bad transistor/transistor in backward or a short in your breadboard. When it doubt just try and build the circuit again with new components as this is a small circuit. Once you get it working make one capacitor half the other and you can see the on-times will be asymetric(This would just be for fun). If you send the output to an ossicope you will be able to see the exact on-off times. Let me know if you have other questions. Right now it is mostly me responding. We will get other socials/forms going soon.

[@tallmatch5866]

Thank you for your quick response!

[@tallmatch5866]

​​@@GlobalScienceNetworkHello once again! I've got a problem with my transistors. It seems like bc547 don't work well with this project. I also have some of 337s but can you suggest me the type of transistors you use? Another thing is that when I apply 5V through Arduino the circuit with 2 or more data latches causes the diodes' light to be very dim and almost unnoticeable.. But if I use 9V battery they light quite brightly. I'm wondering whether you use 5V or higher.

[@GlobalScienceNetwork]

@@tallmatch5866 The bc547 should work but the base emitter-collector configuration is the opposite of the transistors I used which were the 2N2222 and 2N3904. So you have to place them in the reverse orientation I show. This just means flip the transistors if you did not already realize that. I just used a 5V power supply. If the light is dimming then something is wrong.

[@tallmatch5866]

​@@GlobalScienceNetwork Many thanks!

[@deepstories32]

is it possible to build a calculator using this circuit ?

[@GlobalScienceNetwork]

Well I build a calculator using full adders in a different video. We also used counters to build a full computer in a differnt video. The actual operation of this counter is division which could be added to the ALU of a computer.

[@deltakid0]

7:56 There are no J-K Flip Flops in FPGA because they don't provide anything more _robust_ than using D Flip Flops

[@GlobalScienceNetwork]

Yeah, that is a good point. I was mostly saying that a pulse-triggered master-slave style data or JK flip flop is more robust than an edge-triggered circuit on a breadboard. Because just a little bit of noise when bumping the circuit can make it trigger. I am going to post a video about flip-flops tomorrow. I am not sure but the data flip-flops in an FPGA might be master-slave style data flip-flops which are very similar to the master-slave JK flip fop.

[@deltakid0]

@@GlobalScienceNetwork it's impossible to have J-K Flip Flops in FPGA, a CLB is made out of a D type Flip Flop, even if you describe a J-K in Verilog or VHDL what it will end up being is a _physical_ D type behaving like a J-K.

[@GlobalScienceNetwork]

@@deltakid0 Interesting, I do plan to look into FPGA design more to see how the logic gates get reconfigured. Maybe a similar method can be used to change how neurons are wired. Do you know if the data flip flips are pulse triggered or edge-triggered?

[@deltakid0]

@@GlobalScienceNetwork by Pulse-Triggered I think you mean _Level-Triggered_ device such as a Latch, otherwise is an _Edge-Triggered_ device such as a Flip Flop (the former being dreaded by FPGA developers because of its asynchronous nature). By the way, I liked your Binary Counter using only off the shelf transistors, that's an excellent idea to show kids and beginners the very basics of computing (and then show them a 74hc163 for comparison).

[@GlobalScienceNetwork]

@@deltakid0 Thanks for the reply. Yeah, I read pulse triggered a few places and thought that was strange terminology as well. I understand what you are saying about an FPGA not wanting to be level-triggered. One book I am reading suggested using level trigger data latches for the registers and I am trying to decide how I want to build them for demonstration purposes.

[@aligunaydn9912]

Area = width x height. It Area = 1 x 4 . If make it Area = 32 x 32 or even bigger value in width and height. Then it become PHD design tool. Lots of picture figure work.. Just run it with binary bit left shift or right shift counter. Area = 1080 x 1080.

[@GlobalScienceNetwork]

Interesting but I am not quite sure what you are saying.

using bunch of transistors without coding is crazy

sir this video is informative can ou please upload the tutorial of it please sir.

[@GlobalScienceNetwork]

Well this is the tutorial. I included the circuit diagrams in the video as well. Just pause it if want to see the diagrams. If you are unsure how to build logic gates and flip flops, I have other detailed videos about these topics. If you did not watch those this may seem complicated. It is all built on basic circuits though.

The guy has never heard of discrete logic using MSI components.

[@GlobalScienceNetwork]

The idea was to build circuits without ICs to learn the fundamentals of circuit design. If you watch the latest video I built a 4-bit computer using discrete components/not ICs.
