I first discovered your work because I'd seen homemade diodes and wondered about making transistors.

Anyone that doesn't get why rolling your own semiconductors is cool is probably watching the wrong part of YouTube.

Why didn't we have teachers like you for chemistry and physics, not to say electronics? You are so clear in your explanations and totally without any BS.

You're frickin astonishingly intelligent, creative AND funny at the same time. The cool scale doesn't go high enough to properly register your true potential. :-)

You had me at 0:05.

I came here to learn how semiconductors are made....since I teach new operators basic electrical theory at a commercial nuclear BWR and realized that I don't know how they make NPN (PNP) devices. I greatly appreciate your time and effort to teach these principles and your enthusiasm is contagious. Keep up the great work and let me know if you are interested in working in the nuclear industry. 

The good in building transistors at home is that you can do it and it stems the tide of "Gollums" pretending that science is a black art and only machines can produce "Tech".

Hahaha. Did you mention ''common sense''.... On YouTube?

19 people thought the title said making Microwave Chips at home. lol

Wish I had a friend like you back in the day.
