"Z2" - Upgraded Homemade Silicon Chips
Sam Zeloof shows the upgraded second iteration of his homemade silicon integrated circuit fabrication process, producing chips with around a thousand transistors in his garage. It is a short overview of what the home fab can now do.
Why HN readers recommended it

Mentioned a couple other times in this thread but I don't think anyone has linked Sam Zeloof's video of essentially doing this: [VIDEO] It's fantastic and I highly recommend watching it.

In How to make a CPU – a simple picture-based explanationA guy named Sam Zeloof is fabbing functional chips in his garage. I think you might gain a lot from watching his videos about the process. [VIDEO]

In The Semiconductor Ecosystem ExplainedThis was mostly about making a silicon wafer. This video shows more detail on the rest of the process in a home lab: [VIDEO] (blog here: [LINK] )
