Making Microchips at Home - Cooking with Jeri Part1
Why Hacker News recommends it
HN points to it as the example of someone making integrated circuits at home.
What it is
Jeri Ellsworth shows early steps of making microchips at home: cleaving wafers, removing native oxide, testing dopant type with a hot probe, and loading the furnace.

She didn't do anything remotely this complicated, but a few years ago Jeri Ellsworth did do a couple videos of "homemade" ICs. [this video]

i think the word learning is a misnomer here, the term learning in itself is dubious enough look to the best line, and i'd argue one of the most important ideas to ingestively portray to a mainstream population, in 2008 cinema, also an argument could be made to increase that reach.. perhaps in the last decade, century, however hyperbolically you care to extend the reach.. from the film burn after reading(i): CIA Superior: What did we learn, Palmer? CIA Officer: I don't know, sir. CIA Superior: I don't fuckin' know either. I guess we learned not to do it again. CIA Officer: Yes, sir. CIA Superior: I'm fucked if I know what we did. i think what victor is suggesting here would aide moreso in ef

So it seems like he didn't actually succeed in making the pencil from scratch, or if he did, he didn't blog about it. He did successfully make it to mining the graphite, which is more widely distributed than I would have thought: [LINK] Other related projects include: Thomas Thwaites making a toaster from scratch: [LINK] That guy who made a ceramic-tile-roofed house with underfloor heating from scratch just posted about adding a kiln and firing more pots: [LINK] This one is really "from scratch"; he starts the project (in a previous video) by making stone tools from rocks he found onsite. kd5bjo points out, "Don't forget the Gingery book series on how to build a machine shop!" They build a m

Jeri Ellsworth has built working transistors at home. Point contact germanium BJT: [LINK] Etched silicon FET: [this video] The rusty razorblade + pin point contact diode doesn't need anything special because it's a Schottky diode, with a metal/N-type semiconductor junction. If you probe lots of places you can find an N-type region where the dopant is random impurities. But the transistor needs both N and P-type regions, so I don't see any way to build one with common junk. Jeri's point contact example works by diffusing phosphorus from phosphor bronze into commercially produced N-type germanium using a high current to heat it. Phosphor bronze is arguably household junk but I don't think germanium

If optics and photolithography interest you I recommend Huygens Optics on YT [0]. Jeroen, the creator, has an engrossing passion for the material. Jeri's process [1] is wild compared to Sam's lab. [0] [LINK] [1] [this video]
