I think Jeri even etched and baked some diy MOSFET transistors at home on a piece of silicon wafer.
If the OP likes to watch metalworking channels, here are my recommendations:
Stefan Gotteswinter - some serious precision machining
This Old Tony - you won't likely find a more funny machinist. Amazing video production skills and good content.
Keith Rucker - restoration of various old machinery, steam locomotive, steam engines.
Abom79 - The bigger the piece of metal, the better, for this big guy.
Bad Obsession Motorsport - two guys in a garage, building rallye cars with the utmost care for everything. Great video production and lot of jokes everywhere.
