I could probably build a computer from scratch, but it’s not gonna be a modern one with impossibly small microchips and bajillions of transistors. It’s gonna be a room-sized behemoth with only like 8bits of memory.

Sounds like something an alien would say, which is just what you want me to think!

I’m hoping the guy from Primitive Technology will eventually work his way up to that at some point.

Or Steve Mould, who made a processor calculation using water for demonstration purposes.
weker01@sh.itjust.works 5 months ago
He uses a microcontroller though for his breadboard PC. A microcontroller that is built in a fab.

You’d make Charles Babbage very smug with that kind of talk
AngryPancake@sh.itjust.works 5 months ago
If you only care about adding numbers, you can e.g. do that using water or marbles. You only need to build an XOR gate, an AND gate and an OR gate.
In case of water, the gate will have two inputs as water streams. They should be aligned so that when the streams hit each other, the water fill flow into a cup in the center of the aperture. When the streams don’t hit each other, the water passes the cup into another cup on the bottom. Carrying the water out at the bottom is the XOR gate, carrying the water out at the center is the AND gate and both cups together are the OR gate.
Then it’s just about setting up the circuit and that would be a full adder without electronics.

Reject modern devices, true computers require large rooms and the output of a small NPP to operate

You can absolutely go on a tour inside a chip factory, just not in fucking TSMC
Disaster@sh.itjust.works 5 months ago
Apparently it IS possible to make IC’s at home, obviously nothing approaching 5nm transistor gates and therefore the equivalent of lego blocks to precision machined parts… but anyways:

This stuff is half way up my professional alley and when I read it I had to think about the posts on hackaday the last 2 years which kind of document this new homebrew scene made of madmen.
Disaster@sh.itjust.works 5 months ago
I know absolutely nothing beyond the lego-brick level of building and watercooling machines. No EE chops whatsoever… but this stuff is so interesting to me and maybe one day, cost and space no object, having a palatial garage or workshop to muck around in… Just knowing it’s possible really is the half of it.

I was thinking about making some miniature tubes, for audio purposes of course.

I think TSMC’s, a contract maker, market share is even 104.7%, not just around 61%. There are literally no other companies producing chips. Don’t be fooled by sources telling you about a Korean company Samsung or made up words like Intel or Nvidia.

Roswell happened in 1947, first microchips in the 60s, makes sense to me!!
petersr@lemmy.world 5 months ago
The first point-contact transistor was invented in 1947. What a coincidence…
leds@feddit.dk 5 months ago
OK what about the factory that makes the machines in the chip factory…
QuizzaciousOtter@lemm.ee 5 months ago
This one is called ASML and I assume they don’t do tours too.

Racism is a big work in progress in the intergalactic communities.
elbucho@lemmy.world 5 months ago
I mean, anything can look like a conspiracy to a layperson who pays zero attention to 60 years of incremental progress and focuses solely on the end result. It’s the same reason why people think vaccines are evil, or that 5G towers cause COVID.
SirQuackTheDuck@lemmy.world 5 months ago
5G towers do cause covid. Without 5G my WiFi would be far too shitty to book a cinema seat and get nice and infected by Karen her unvaccinaged crotch goblins.
makingStuffForFun@lemmy.ml 5 months ago
I was of the understanding, it was in fact covid that caused 5g towers.
I think there’s something in that for all of us… mmmm yes

You mean like how autistic persons cause vaccines?

Any sufficiently advanced technology is indistinguishable from magic.
But also, it would be nice to invest a bit more in science and engineering (with smaller class sizes, more educated teachers, and more hands on experimentation) rather than doing “teach the controversy” shit in auditorium sized rooms full of kids who have already been indoctrinated to believe in magic.
