Computers are just single ALUs that deal in numbers only; Turing machines manipulate data without caring what those data are Comment from : Rohan Zener

Amazing Comment from : nelson ndungu

🔥 Comment from : Professor Linux

Don't electrocute yourself Comment from : The Gorn

This stuff is so cool Comment from : Railrat

True brilliance is figure out which light will on when first power it on Comment from : Peter LDeegan

What's the name of the book Comment from : ayan roy

power supply😏 Comment from : Shikhar Verma

the book in the video is Practical Electronics Handbook brBy Ian R Sinclair Comment from : blue bird

Isn't it "flip-flop gate" ? Comment from : Gamedit

This is so helpful Comment from : Eric Farias

Got to love a bit of booleanbrIt a grate day when you realise that you can calculate any possible logic with just those 6 components (and, or, nand, nor, not and nnot)brThat last one is more commonly known as a bit of wire Comment from : KillaBitz

How is this video helpful, pedagogically speaking, in understanding computer memory? Most of the video is the guy fumbling with a circuit speaking in a difficult to understand accent Comment from : Ed Powers

Gem of a video Comment from : Batman Fan

you let the magic smoke out everyone knows that magic smoke is what makes electronics work as soon as the magic smoke escapes, things stop working Comment from : Mark M

What book does he use to see the circuit diagrams? Comment from : Tyler Fanuele

3:25 That's why you do NOT manipulate wires or any components with an active circuit Comment from : Hampstead343

Looks like dual delay with crossfeedback diagram Comment from : Yuppi

That book isbr"Practical Electronics Handbook" Comment from : Arup Dutta Bappy

I understood this logic element from school in the seventies but I was never able to get comfortable with how you turned it into anything useful functionality wise I suppose that it merely stores binary numbers and not programs per se Perhaps it is just processing and programming that I cannot envisage Comment from : Robin Wells

omg they made the RS nor latch from Minecraft into a real thing Comment from : chachasenri

DaaaaaaamnI always assumed it was something to do with tiny capacitors "storing" or "not storing" chargesI guess I was rather "out to lunch" 🤯 Comment from : Betty Swunghole

@Computerphilebryou can't explan how they doing in real cpu micro transistorbri tried it for build 8 bit adder with finfet 3d structurebrthe problem for asking is the unique not gate source power linebrother gate can share the source line, brif share will not gate, after the following gate will grounding and turn offbrhow the real cpu fix that should including lot of unique source line only for not gate? Comment from : 抺香膏馬利亞

He can hear the ram writing Comment from : MaxCE

When in doubt stuff about Comment from : Rrobert Garnett

wonderful explanation! It’s so nice to see someone explain these things in a bit of a detail, perfect for engineers Comment from : Mark1Mach2

My electronics profesor would be irritated by that deficient protoboard Comment from : 2cavas

So memory is stored when the circuit gets filled up with all the relays being left open or closed?brbrAlso if the electric is turned off how is the circuit/ relays still saved and not all gone back to its original state? if that makes sense Comment from : The Matrix Weave

How do they make the animations? Comment from : Neel Sandell

he: I hope this gets edited outbrme watching it: editor betrayal! Comment from : blank

Ilike Comment from : Mengstu Tesfaw

Im glad he isnt an electrician xD Comment from : Imagine A World

How did you label the outputs as Q and !Q in the beginning ? Comment from : Anzal Khan

absolutely brilliant Comment from : Fyre Rayne

Hard to follow with continual cutaways to his face, wires cover up the pins being moved, fingers get in the way of the shot Ben Eater does a better job Comment from : southern katrina

oh no my brain got not'd Comment from : nobeltnium

Sr latch, barbaric Comment from : Duckson Plays

This is well explained in the book "Introduction to computing systems: from bits and gates to C", but Ben Eater's videos are also very good And finally I discovered this channel too Great! Comment from : Teo Halfen

him killing that breadboard/components is basically my electrical engineering degree in a nutshell Comment from : D O O

Man!The one who found this out ,he is a genius, he has made a non-living thing to store MEMORY,that's what makes it fascinating Comment from : anirudh varma

This video helped me understand this topic in the Coursera course From Nand to Tetris Comment from : Chidi Justice

Can anyone explain how this is called storing, i understand how it works, but how can you store more than one bit using this method? Comment from : James B

That's just an R-S flip-flop :) Comment from : Brad Camroux

Book: Practical Electronic HandbookbrOk let's go Comment from : momo

11:13 that zoom Comment from : Adam Hunt

0:30 That’s a Atari ST logic board How do I know? 😉 Comment from : Edwin Schaap

I just wanted to say that I think the graphics you used in this video were very helpful In particular, I enjoyed the pattern of the logic gates you superimposed upon the computer chip that is displayed at 8 minutes, 55 seconds of this video This inspired me to ask the following question, do you know if anyone has ever manufactured one of these chips with the logic gate patterns either painted on top of the chip or perhaps etched into the top of the chip ? I think this type of display placed on top of the chip would be a nice aid for people learning to use this technology Or maybe a sticky label could be added showing the pattern on top of the chip ? Comment from : Stevie Ray

I do like the Computerphile videos But this one very poorly visually presented Comment from : Dennis van Mierlo

Steve is brillant Comment from : Darko Bakula

The video would greatly benefit from drawing the diagrams of the circuits in true Computerphile style Comment from : petarpetrov89

I got PTSD of my college years by watching this Comment from : Widi

Is the mouse still going 6 years on? Comment from : James Buchanan

What is a and gate or nan gate he was talking about Comment from : Mohit Agrawal

And he replaced the AND chip with the NOR chip without disconnecting power #rebel #nofucksgiven Comment from : Richard Tocci

best computer graphics to explain this Comment from : niksatan

reverse-engineered alien technology brIT HAS TO BE !!!!!! Comment from : Keith Wilson

What's the logic book you're using? Comment from : Vishal Arya

Computers' ram is bnot/b based on logic gates Comment from : IAmAgainst

How did i get here Comment from : Pegglez

I've seen this arrangement using pneumatic valve blocks the pull down resister function was an a air bleed instead Comment from : Keith Citizen

But can it run crisis? Comment from : praveen kumar

I'm out 11:40 Comment from : lifelongpilot

THANK you THANK you THANk you! Comment from : The Ultimate Reductionist

what book was that on 3:00? Comment from : Donovan clark

Memory is a rs nor latch, at least that's how it's called between redstoners Anyone here? Comment from : Cosimo Baldi

Please, could you say the name of that book? Thanks Comment from : Lucas Alves

the office: electronics Comment from : Streameant

How come every single computer guy looks like this? lol Comment from : SETH other

Practical Electronics Handbook br2nd Edition THAT HE USE Comment from : almuhanad Ahmed said Alhashmi

Name of the "Gate's almanac" book? Comment from : Emanuele

7:10 diagram in s really nice! Comment from : MrPlaiedes

Is all human are fool Comment from : tech guru

You should do a video on ternary cumputers such as Setun Comment from : Jacob Stewart

I hope that your next videos are more direct to the pointits so time wasting Comment from : Experimentor User

i love the smell of burning electronics in the morning Comment from : Drayvel Harris

What is that book I always have to Google the the data sheet Comment from : Veepedaldude

They should have mentioned the S-R flip-flop's inherent flaw, which is: if both R and S are 1, on the output Q and /Q will be equal to each other, which is obviously not how boolean algebra should workbrOf course there is an easy way around this, just don't let R and S be equal to 1 simultaneously And the J-K flip-flop fixes this issue, but that requires a clock signal to workbrJust thought this should be mentioned when talking about S-R filp-flops Comment from : Botond Keresztes

KitKat a lot of fun ! #Epitech Comment from : Gideon

Great!! Comment from : morominaolenmina

I just figure out why minecraft players call this an 'rs nor latch' I had no idea the name was based on actual terminology Comment from : Ethan

what is the name of that book he was reading with the different logic gates on those chips? Comment from : Curtis Hubbard

Why didn't he show what happens when both inputs are 1? That's the only non trivial part Comment from : Nikola Zlatkov

Which animation soft is used in the videos of this channel? Comment from : Null Void

This was by far the worst Coputerphile video i have watched Horrible explanation at the end Comment from : GifCo

As a software type, I wouldn’t understand a thing from the video if I did not know Boolean algebra Comment from : Leonhard Euler
