Why Hacker News recommends it

HN likes Ellsworth as a hardware tinkerer, and cites the video as proof that transistors can be made with low-tech, DIY fabrication.

What it is

Jeri Ellsworth demonstrates a PMOS transistor she fabricated herself in a home chip lab. She shows some of its electrical characteristics.

This channel might be of interest to you: [this video] One of my favorite channels as she's done many projects I've had interest in.

Jeri Ellsworth, for people who don't know, does really interesting hardware stuff. "TSA body imaging at home" ( [LINK] ) "Home made EL wire" ( [LINK] ) "Recording Audio onto floppy discs" ( [LINK] ) "Home made transistor" ( [this video] ) "Homebrew NMOS transistor" ( [LINK] )

up to the point that we see actual infrastructural collapse. I mean, I've seen Jeri Elsworth bake her own transistors in the oven and stuff (each one being about the size of your hand) but somehow I can't picture a chip fab based upon such transistors... call me old fashioned. [this video]

Jeri Ellsworth has gone "deeper" into the process and made a few transistors, although at a much larger scale: [LINK] [this video]
