I need couple simple vacuum diodes such as a filament and an anode inside a glass tube. If your lab can make them, I will buy. Please let me know. Thanks
You are a fantastic video creator as well as being a genius!! My Grandfather did all the same things you do. These skills are being lost and very few people are stepping up .
Great job. kudos to getting any joy out of borosilicate glass without an oxy-fuel torch. You can add a getter from a broken commercial tube when you want a bit longer life.
Nice way to show that even relatively moderate tooling ( may vary from your definition of moderate ;-) can get you there. Good work on the tube and video.
Yeah, I'm also thinking how to get around that. I do have a rotary vane pump. But it's not enough. I've read somewhere that a dry ice cold trap could work. But I'm currently trying to find someone who successfully made vacuum tubes this way. I kinda doubt, that this works.
@@paulm3079 I think I meant with the rotary vane pump. I got around this by having another passthrough for a titanium filament that absorbs the leftover gas when it's heated. (Basically a titanium sublimation pump)
Just ran across your video! Excellent attempt using the mos primitive setup I have ever seen!
This is the LORD's work right here. Integrated circuits come straight from Lucifer the Son of the Morning.

Great Work Buddy You've Got A New Subscriber From Birmingham England

Legend, i can't wait to get all the materials needed to start making vacuum tubes

good video, but i wouldnt call a rotary vane pump + diffusion pump "simple materials"

Neat!
An experiment that is worthy of high praise. A lot of work has been done.
Truly amazing.
Ok
