Room temperature superconductor created

Viable superconducting material created
https://www.sciencedaily.com/releases/2023/03/230308112130.htm

The researchers describe a nitrogen-doped lutetium hydride (NDLH)
that exhibits superconductivity at 69 degrees Fahrenheit (20°C)
and 10 kilobars (145,000 pounds per square inch, or psi) of pressure.

Come back to us when we can buy a reel of superconducting cable from Mouser or some other broad-line electrical retailer.

With this stuff the hydrogen doping will diffuse out too fast for long term use.

You should have heard slowman boasting about it if HE had come up with it.
Slowman is just anti-science.

BTW what processor core did you code in FPGA, in what language and what FPGA?
Did you open source it?

Scarcely. I do know enough about science and technology to know the difference between a promising result and a practical product, even if you don\'t,

> BTW what processor core did you code in FPGA, in what language and what FPGA?

No processors, and the language was PLACE , and it was a long time ago. The FPGA was an ICT PA7024. In the end I didn\'t code it - Paul Buggs was around and could do it as fast as I would have done, and there was stuff that I could do that he couldn\'t. Since then I\'ve looked at coding stuff into Cool Runners, and I\'ve got a couple of dozen of them in cupboard. but the project turned out to be impractical.

My employers wouldn\'t have liked that. They did like me turning the project into a published paper after my wife had moved us to the Netherlands, but they wanted to have secret stuff that they could sell to anybody who might have wanted to copy it - not that it would have been all that difficult to replicate.

This may be true, but we are slowly moving to more and more practical
superconductors. Remember the starting point was liquid helium for cooling?

I\'m not that old.

\"Superconductivity was discovered on April 8, 1911 by Heike Kamerlingh Onnes, who was studying the resistance of solid mercury at cryogenic temperatures using the recently produced liquid helium as a refrigerant\"

I read about it when I was old enough to read, back in the 1950\'s.

I\'m fairly sure that we will get there eventually, but we are still some way from a practical room temperature superconductor.

That\'s been done before, at insane pressures. 10 Kbars is an

Yup. OTOH cuprates are stable at ambient pressure. You can make a LN2
cryostat a lot bigger than a 10 kbar pressure cell, and it\'s easier to
get wires in and out, too.

It was my own design. I program in Forth, which is a language based on a virtual stack machine. It is popular in the Forth community to design stack processors which make the language easy to port to the processor. By \"port\", I mean the entire development system can be hosted in 8 kbytes of storage. Or in smaller implementations, the processor is just a processor and a PC is used as a cross compiler.

I tend to just program in assembly since it is not much different from Forth and I don\'t want the tools in my way (not that Forth does much \"getting in the way\"). I can also tailor the processor to the task. I had one design that was optimized for handling interrupts and got rid of most of the stack juggling by adding instructions with offsets into the stack. It reduced the instruction count by a third! My designs are always simple, with 1 clock per instruction, so it also reduced the execution time by a third.

I typically use VHDL and I\'m FPGA agnostic. The board I\'m designing now will use a Efinix FPGA because that\'s pretty much all I can buy, probably the T20. The T13 is pin compatible, but the cost difference is minimal, around $10 vs. $12. I will qualify both, and use the T13 when production is stable and there is clearly no need for the larger part. Oh, it won\'t have a processor of any sort. It\'s all dedicated hardware.

every single one programmed in asm, Fourier transform no problem:

just a few bytes.
At one point the code space was full, noticed later the PIC also has a relative jump,
so replaced all jumps by relative jumps and gained some extra bytes space.. for later additions...

Hydrogen molecules are small and they diffuse through pretty much anything eventually, Helium is worse.

Lutetium has 71 protons and an atomic weight of 175. It\'s atoms are huge It\'s \"hydride\" is just hydrogen atoms nesting in the gaps between the lutetium atoms.

The nitrogen atoms may stay put. Hydrogen gets around.

LOL!
You should have heard slowman boasting about it if HE had come up with
it.

Slowman is just anti-science.

BTW what processor core did you code in FPGA, in what language and what
FPGA?

Did you open source it?

It was my own design. I program in Forth, which is a language based on a
virtual
stack machine. It is popular in the Forth community to design stack
processors which make the language easy to port to the processor. By \"port\",

I mean the entire development system can be hosted in 8 kbytes of storage.

Or in smaller implementations, the processor is just a processor and a

PC is used as a cross compiler.

I tend to just program in assembly since it is not much different from Forth

and I don\'t want the tools in my way (not that Forth does much \"getting in

the way\"). I can also tailor the processor to the task. I had one design

that was optimized for handling interrupts and got rid of most of the stack

juggling by adding instructions with offsets into the stack. It reduced

the instruction count by a third! My designs are always simple, with 1 clock

per instruction, so it also reduced the execution time by a third.

I typically use VHDL and I\'m FPGA agnostic. The board I\'m designing now will

use a Efinix FPGA because that\'s pretty much all I can buy, probably the

T20. The T13 is pin compatible, but the cost difference is minimal, around

$10 vs. $12. I will qualify both, and use the T13 when production is stable

and there is clearly no need for the larger part. Oh, it won\'t have a processor

of any sort. It\'s all dedicated hardware.
Thanks,
Yes Forth, I have looked into it but never wrote any Forth code.
I\'v come across it at work, and managed to understand it and do faulty finding.

I like asm too, as in micros it gives me 100% control of the hardware and
timing.
But more complex chips, some with non-public code parts (like at least the
old raspberries had),
ARM stuff, I prefer to program in C.
And x86, did a lot of x86 asm and 8051 asm back in the eighties, then the
boss decided we should all use C
and we had C lessons.. as the programming department could not get used to
all the asm,,
Was no problem for me as I already used C in several projects at home.
I played a bit with Xilinx FPGA, mostly used for code cracking and some video
processing,
programmed in Verilog:
https://panteltje.nl/pub/FPGA_board_with_25MHz_VCXO_locked_to_rubidium_10MHz_reference_IMG_3724.GIF

using the Digilentic development board.
Small FPGA boards seem to be very cheap on ebay.
