The biggest hurdle is an electron microscope for examining the features of his transistors. A good friend found a broken one and with $1000, a fair amount of know how and a lot of time they were able to repair it to working condition. As for the photolithography device? The light from a conference room projector is beamed through a microscope to trigger the light sensitive coating on his wafers
Zeloof’s chip was his second. He made the first, much smaller one as a high school senior in 2018; he started making individual transistors a year before that. His chips lag Intel’s by technological eons, but Zeloof argues only half-jokingly that he’s making faster progress than the semiconductor industry did in its early days. -------------------- Zeloof started at Carnegie Mellon University, hacking on pieces of garage fab equipment in his dorm room while studying electrical engineering. Although he says he followed safety protocols, the university took exception to the x-ray machine in his dorm room
While Intel has a lot more money, it also has a long history of difficulties living up to the promises they make to the American government, meanwhile Sam Zeloof has already built his fab and his process technology is shrinking at a much higher pace than Intel’s.

Weird science - optics and lasers.
“Yes, I understand the process.
But not everyone finds the factory/epa settings optimal for their needs?
You can sometimes find them offshore...”
Obviously you don’t understand if you think you have to go offshore.
Now show me how it works in an actual IC that runs in a computer
“Video shows it used in a guitar pedal as explained in the article.”
Nope
Nope
“And here I thought I was hot stuff writing 6502 assembly routines in high school.”
When I was a freshman in college we used toggle switches!
—”Nope”

Somewhere I saw a better video... but this came up first...
So you are happy with the stock EPA tune?
Link: Distortion pedal with all homemade semiconductors, only one external component (cap for AC coupling)
Not a pedal
Only a reverb which can be built with 4 transistors.
Above my paygrade if he is not using resistors and capacitors.
“So you are happy with the stock EPA tune?”
As previously posted, I upgraded from my stock 2019 to the 2020 stock tune.
Hard to not be happy with 750 hp and a five year warranty.
Well, thanks. It appears that these days, I think in Ada (the language, that is, sigh), and it appears to be reasonably well remunerated, so I’m not complaining ... much.
Woo-hoo! Punch cards too?
I would jest, except that honestly, I’d probably be better off if I was a boomer...
—”Hard to not be happy with 750 hp and a five year warranty.”
FIVE YEARS! Amazing.
But that clearly says there are more than a few horses to be rounded up by a wild cowboy.
” Punch cards too?”
FSU and UF ran a compatibility match using using punch cards.
We got five names of the opposite sex at the other university.
On of the five Ingot was an old HS GF!
