Making Intelligence with Basic Switch

Intelligence and Consciousness is made of simple switches, let’s make logic with relays!

HEY! Hope you had your dose of switch this morning to keep your intelligence high!!
at 2:22 on my OR truth table I forgot to change the text from AND to OR! But it is an OR and not an AND!

this is a great intro, for digital electronics 😌

As a small child in the 1970s, I remember my Father demonstrating logic to me by building a 4-bit adder, using indicator-lamps, toggle-switches, and relays, all mounted on an aluminium frame.
Lots of neatly soldered wires all laced together into bundles with waxed string, telecoms style.
He used to work for the UK's Post Office Telecommunications, back when they ran the national phone system (before BT was formed), then he taught electronics.

Hey Mehdi. I don’t know if you ever look back through comments, but if you do I want to say a massive thankyou.
I’m 34 and have spent my life as an electrical installation engineer, now following an injury I’ve retrained as a design engineer and continue to search for a career in something I feel so passionate about.
This video, just like all your videos has inspired me to learn different aspects of electrical and electronic circuitry that I never considered before, and continue to expand my knowledge.
I now want to get a deeper understanding of Logic!

Anyways, keep up the great work mate. 100% best channel on YouTube 👍🏻
Once again, many thanks.

programmers: "Hey, I've seen this one before!"

[PlasmaChannel]

You may have demystified the most pixie-dust topic out there. Thank you my friend.

This man officially wins youtube.
The first 5 minutes are enough to understand digital logic.
The rest of the video covers the entire course in digital logic.
I am but a humble mechanical with a specialization in mechatronics.

Thank you for another elegant and fantastic crash course video! This perfectly summed up the basic fundamentals of my Digital Logic and Design course at University. One thing thats really interesting is using transistors to make switches and gates. When we use PNP or NPN transistors to make gates our professor highlighted that it's impossible to make native AND and OR gates due to how the transistors work with logic. We can make NAND and NOR gates really easily however, so we just use an inverter on the output of inverted logic gates go make them normal gates. Though we can use boolean algebra to determine if it's a good idea to do so, or if we save transistors by using NAND, NOR, and XNOR gates instead.

9:34 The delayed reaction censor blur makes it twice as funny. xD

[TheAndromeda]

This was quite an informative refresher! Thanks!!
Also, that was such a smooth transition at 11:14

[yordanyankov]

I absolutely enjoy revisiting old topics through your videos and filling in some gaps. Thank you!

[thejackal]

I'm getting the impression that I learn best through violence and partially angry teachers. Thanks, Electroboom!

Mehdi - I really appreciate your attention to detail… at 9:40, you clearly said “NAND” originally, but you went back and dubbed it over with the correct terminology, which tells me that you really paid attention when you went back over this material. You’re a great teacher (even if I don’t 100% understand everything all the time and usually need to re-watch a few times), and I just wanted to let you know that I appreciate your meticulousness… as well as your sense of humor. :)

I got my BS in computer engineering in 2019 so this is the exact stuff i learned and had to apply when we got to microcontrollers and especially FPGAs. Its really genuinely amazing to see you covering a topic i learned in school and its still familiar!

[TheREALHelly]

Coming from a computer engineer, the amount (and quality) of information covered in this video is simply astonishing. Thank you for your videos and your brow

[youradvertisehere]

Being a developer for 20 years now i cannot stop watching him explaining what a statement is. Great video

[Edsabre]

I'm taking Digital Circuit Design this semester and I swear you've explained the first month of classes in this 15 minute video. Bless you, sir.

[AERIEDM]

I love all of your videos. This video in particular explains the basics of logic which is great. You could follow this up with explaining bits, bytes and data strings. This is basically the introduction into modern computing. Amazing.

The moment you realized as what your drawing can also be interpreted 😆
