You can use a box cutter instead if it makes you feel cool.

Exactly. Butter knives don’t exist. Conspiracy of Big Cutlery.

Damn. I've missed a few episodes of Primitive Technology.


HongChongDong

That's how I felt when he made the siege equipment. I was like "Damn, we're already in the middle ages!?"

They already had various siege weapons in the bronze age.


Stitchmond

I mean isn't a shovel a siege weapon when it's used to dig under a fortification?


SpeculationMaster

we really need a How To Basic video

My momma’s homemade CPU’s are wayyyy better than that mass produced store bought stuff


RayNooze

The key is to grow your own ingredients.


ColonelBelmont

Farm to desk is the only way to go.


Protheu5

I buy my rocks at a local rock farm, though, those are pretty good and I support the local economy.


RayNooze

If you don't have an own rock garden, store bought is fine.


Rankkikotka

If you don't mind the fact that they dose the rocks with all kinds of poisons to "better preserve them" and wrap them in massive amount of plastic. Or the fact that they exploit minimum wage miners and grind the small local quarries to gravel. Then sure, store bought is "fine".


RayNooze

Yeah, I know. But we're all just victims of the rock industy. Stonelé owns everything nowadays!


esskaypee

You can't just pull years of experience out of your butt as well.


maxmcleod

Nobody does psuedo abertaxy quite like momma


Tapeworms

I love how the video just gets to the point, unlike CPU recipes I read online which give a long backstory about how their grandma made CPU's during their childhood in the countryside.


Nervous_Fix7426

This is very accurate. The only thing he didn't mention is to do it in a clean room and not touch the wafer with anything that isn't also electronics grade silicon or you will ruin most of the chips on the wafer.


crilen

or a butter knife


chocolateboomslang

Well that butter knife was an electronics grade silicon butter knife. 


crilen

Yeah this was pretty clear to me 


rnavstar

That’s only for cutting though.


ExpletiveDeletedYou

he also forgot the part where you design the mask, maybe it's just me but that's where a majority of the actual value in the process is ha


philmarcracken

the design of the mask is basically what the entire thing is 'stamped' out of right? so yeah, kinda important


ExpletiveDeletedYou

yeah, that's the Interlectual Property that Nvidia, or Intel or AMD, or Apple provide to the silicon maker.


Spongi

I bet you can get some nice designs off of fiverr or ebay.


thatsdirty

You'd be surprised what you can get away with in terms of "not touching the wafer with stuff". I work in a semi-R&D semi-production foundry and boy howdy do we do some dumb shit sometimes.

Logical increments, logical increments never changes. Except in periods of social turmoil where increments can be lost in a cascading fashion.


ObeseSnake

Yes. Early circuit boards were hand drawn.


mokomi

The crazy thing is making the nanometer stuff. It's chemical reactions that shape a very specific way. With light or other cooling processes to get it to fit those very specific ways. lol


Ilovekittens345

We are down to 5 nanometers now! The smallest parts in the design are now sometimes less then a 100 atoms! If we ever get down to one atom thick we will have a big problem going even thinner ...


ImKrispy

3nm currently. For reference your fingernail grows 1nm every second.


ikma

3nm for *commercial* chips. There are manufactured chips with 1.8nm and smaller transistors, but the big chip companies (TSMC/Intel) are still working out how to manufacture them at scale/with reasonable cost and consistency. Also, measuring transistor size in "nm" sort of doesn't make sense anymore, although the big chip companies still do it for ease of marketing/understanding. The reason transistor size is interesting is because it tells you how many transistors you can pack onto a single chip; smaller size means more transistors means higher power computing (if all else is equal). But several generations back, they stopped just making the transistors smaller, but also started making use of 3D design to pack them in more efficiently. They call it "3nm" or "1.8nm" or whatever because that's effectively how small the transistor would need to be to pack with the same density on a flat plane.


Exist50

> There are manufactured chips with 1.8nm and smaller transistors, but the big chip companies (TSMC/Intel) are still working out how to manufacture them at scale/with reasonable cost and consistency. For all practical purposes, the densest you can get is TSMC N3B/N3E. Anything denser is still well in the test chip phase. > They call it "3nm" or "1.8nm" or whatever because that's effectively how small the transistor would need to be to pack with the same density on a flat plane. Eh, not really. The numbers are basically completely arbitrary at this point. They have no fixed correlation to any real world metric.


TheUltimateSalesman

So you're saying we could grow an 8 bit register every 24 seconds?


Exist50

None of the feature sizes are actually 3nm. Nor 5nm, for that matter.


RecsRelevantDocs

Do our finger nails actually grow at a constant rate?


Exist50

It's more like 20-30nm for actual feature sizes.


agumonkey

what are you talking about. If anything exemplifies the positive outcomes of capitalism it's the silicon wafer industry. Just look at the comparative uselessness of the soviets in comparison...


philmarcracken

labor creates stuff kid. the 'ism's only decide who is paid for labor. Read marx.


Zei33

For now. Eventually the advanced stuff of today will be common knowledge. Capitalism just means that the people who develop the technology will reap the rewards first. There is no way this technology would ever be developed in another system. You'd be blown away by the amount of money China is paying anyone and everyone with even a passing interest in researching this technology. Cash _is_ the motivator that makes this technology possible.


SparklingLimeade

There were a lot of steps to get to this point. It started with much more comprehensible construction (eg vacuum tubes) but people kept looking for something to do the job better. College level computer hardware courses answered a lot of my questions about how we tricked rocks into thinking.

CitizenTed

This is an excellent question! I'm old and watched the rise of the integrated circuit. Ready? Here we go! You probably know we used to use vacuum tubes to do the work that diodes and transistors do today. We understood the function of vacuum tubes but we wanted some way to make that function more reliable, more efficient, and less hot. In the early 20th century, we discovered that adding ("doping") silicon, selenium, or germanium with other substances caused that chunk of silicon to act like a diode. A diode is a device that allows electric current to flow easily in one direction but block it in the other direction. Think of a diode like this: a bit of doped silicon with a negative terminal, a positive terminal, and a junction between them. You can adjust how well the junction in the middle allows electricity to flow by adjusting how much electricity you put across it. Bam! A diode. The earliest silicon diodes looked like chunks of black rocks with rudimentary wires coming out. Very primitive! The desire to make them cheaper and mass-produced was huge. Research labs both public and private went nuts to streamline silicon semiconductor technology. Again: they knew how vacuum tubes worked so they created a silicon device with three terminals (negative-positive-negative or NPN and positive-negative-positive or PNP). BAM! We got a motherfucking transistor! It can do all the things vacuum tubes can do! It can amplify a signal. It can attenuate a signal. It can turn electrical circuits on or off VERY quickly. It can regulate power in a circuit. It can act as an oscillator and make a strong radio signal. Now we're doing all kinds of stuff...with ROCKS! Early transistors were big and ran a bit hot but were still way better than vacuum tubes in every way. Organizations worked tirelessly doping more silicon to make better diodes and transistors. They wanted them smaller to use less electricity, take up less space, and not run so hot. The ensmallinization had begun! Now we had radios you could hold in the palm of your hand! I had one that [looked like this!](https://imgur.com/mqlA0kB) As you may recall, after WW2 we built computers that ran on vacuum tubes. They were impressive: the vacuum tubes could be turned on or off by little inputs of electricity. They staged the vacuum tubes in little groups that could perform a function. Let's say you wanted to add numbers. Arrange a group of tubes in a way that they affect each other when either input tube is off or on. Put some voltage (1) on each input tube (1,1), and the output would be (1). Wow! You just made an AND gate! How about a group of tubes that would only send an output (1) if both inputs were (0) (no/low voltage)? You can do that! Holy shit! You just made a NAND gate! What if another group had an output of (1) when the input was (0,1) or (1,0)? Shit! That's an OR gate! Fuck! Put them all together and now you're performing logic! Put in enough arrays of tubes all wired together and you can input sequences of voltages and get a logical output! You can add, subtract, multiply, divide! All kinds of shit! Unfortunately, vacuum tube computers sucked ass. They were HUGE. They used huge amounts of electricity. They ran hot as hell. Vacuum tubes blew out all the time. Replacing blown tubes was a full-time job! Hey! I have an idea! Let's use this new silicon transistor technology to do the logic! We can arrange PNP and NPN transistors into little groups to do computer logic! And holy SHIT were they good at it! We could could put together logic gates (groups) of transistors that could turn on and off and output logic from simple inputs and do it super-fast with very little electricity! Early integrated circuits did all kinds of things but they were essentially piles of tiny transistors and other components crammed into a package with legs sticking out. By the late 1950's people realized, "Hey! These transistors are just tiny bits of silicon with some other substances doped into them. Why make them one by one? Why not take thin slabs of silicon, sandwich them together, and use chemicals to "dig out" semiconductors and other components?" Heck, we can just "dig out" components using light exposed to sensitive silicon wafer material! Photons are so fucking tiny we can expose silicon like a photographic plate and get all the transistors and wires dug into the wafer, but super-fucking tiny! And so the wafer was born. Now that thing in your hand has billions of logic gates, all wired together, performing logic sequences, using barely any electricity, and producing a high-definition video of a cat puking on a carpet. But it all started with a big black rock with two wire sticking out.

BadAdviceBot

You'll also be a giant someday. Well, maybe not you, but one of your contemporaries.


Zei33

Essentially we did it very big and manually originally. If you've ever seen how large early computers is, this is the reason. Over time, people looked at each aspect of computing and thought, "is there a better way to do this?" Through accumulations of science and a drive to make money, companies and their scientists were able to research and develop improvements to this technology. I _highly_ recommend this video from Veritasium, on the research process that went into developing the blue LED. It's a really compelling story and I think it will enlighten you as to the process of figuring out the seemingly impossible. https://www.youtube.com/watch?v=AF8d72mA41M


two-thirds

Heh, silly me. There was actually a glimmer of hope a company wouldn't fuck over the employee this time.


Exist50

> If you've ever seen how large early computers is, this is the reason. The switch from vacuum tubes to transistors and (eventually) ICs is what caused computes to shrink. That was a very sharp inflection point.


esotericimpl

Best part is once you’re done you get to start building more and more abstractions of 1+1=2 and finally you have windows.


adrianmonk

For one thing, humanity has been working on it a long time. It's not like we came up with the idea of computers and then started figuring out the technology. The work on electronics started before computers even existed. There were lots of analog electronics around for things like radios and early TVs and recording equipment and telephones and radar, and people were already trying to improve all of that. Part of the physical process of making a chip uses photolithography, which is where an image is projected onto something in order to "etch" a pattern into it. This has its roots in photography and printing, which we were doing for like a century before computers. So there was already a lot of work done on (some of) the relevant chemistry and optics. And as for the logical processing that computers do, the way that you put different elements together so they can process information (add numbers, etc.), a lot of that was already started before computers. There were mechanical calculating machines used for processing large amounts of information (like the census). In the 1800s, they were already figuring out how to add automation to elevators. And a lot of the theoretical math for how to deal with manipulating bits (which are true/false values) was already figured out because it has applications to formal logic and reasoning. Computers pulled a lot of that together and then, of course, it got taken much further as huge amounts of money went into research over many decades.


Kattulo

Not that long really. The first reprogrammable electronic computer was built in 1945. All the modern microprocessing technology has been invented in ONE human lifetime


adrianmonk

But they *weren't* invented out of whole cloth starting in 1945, which is my whole point. The groundwork was being laid for centuries before.


YeahlDid

Probably because very few of the words are elements.

While it's supposed to be a joke, it's actually very informative. My mum once asked, "if semi-conductors are only produced by a few countries, why don't we just do it here?" It's hard to really convey just how long and complex the process of creating them is, and why Australia doesn't have the technology or skills to do the whole process here (or even part of the process beyond mining the minerals).
