Z2：升级版自制硅芯片

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 likes it: HN uses it as the go-to proof that small-scale, hobbyist chip fabrication is real, and as an entry point to the topic.

“It's fantastic and I highly recommend watching it.”
