Where can I find some tutorials about how to make pic related at home?

Do you mean an integrated chip or a CPU out of discrete components?

Is it theoretically possible to build a computer with comparable power to a modern one like that?
How big would it be?

If you have a multi-billion dollar fabrication machine that can print at <20nm? Sure...

>> No.1844177

Theoretically yes, but insanely far from practical.

If you really just want to program your own CPU, you can just use an FPGA. It won't be fast, but it will be a reasonable speed that you might be able to get a simple OS running on it.

If by that you mean floating point operations per second then absolutely fucking not. There is a hard goddamned limit to computing "power" (if there was such a thing at all) defined by propagation delays and rise/fall times involved in the discrete components. Could you, for example, make a (very fucking slow) clone of an 8008, 8086 or even a Z80? Yes, you could, and it has been done. Why would you do this? Simple masochism of course.

Start by pounding sand for a few days. When you tire of that, pick up a thrown out old pc and remove the CPU. Tell everyone you know that you made it.
Got more stupid questions for DIY????

You can make a 32 bit computer diy. It will run like turd but it i will be /diy/

I've seen RISC-V implementations running at 160MHz on a modest FPGA.
You won't be competing with Intel or AMD, but that's not all that shabby.

risc-v using premade chip, I was talking about bread pure true /diy/ implementation.

You should look into FPGAs and fpga programming. You are basically making a cpu. Applied science recently did a video on doing photolithography at home with a large format camera. There is also videos on YT of people that have made half adders and full adders with a quartz clock etc.

I'm not sure what you're trying to say.
The RISC-V ISA exists, but it's still up the maker to actually do the hardware implementation.
Also, the base RISC-V instruction set is not that complex, it's basically just another take on MIPS.

Some people have managed to fab their own chips at home. It's all hobbyist tier though.

>> No.1845517

>>1844940
I've seen transistors, and I think a really simple op-amp.
Fabricating a CPU is still way beyond the reach of hobbyists though.

On the flip side, there are some labs which you can pay to fabricate a single chip for you.
Basically they take a bunch of people's designs and put them all on the same wafer to keep costs down.
It still costs 10 grand a pop though.

It could be a piece of art. Absolutely worth more than any of the modern shit they have out now, anyways.

If you're talking about designing your own CPU then go for it. You can avoid all the unnecessary cruft they put in all the commercial designs, and yours will be faster and use less power.
