You'd love Sam Zeloff http://sam.zeloof.xyz/
he makes DIY transistors
Don't get me wrong, he's a genius, but everytime he transitions into "anyone can do this stuff!" It rubs me the wrong way
The envy I feel when I see these guys with such equipment is enormous. I really would love so much to have a loaded electronics work bench especially oscilloscopes, LAs etc. and of course the time to actually play with it. :-(
