I'm looking to experiment with making a cold cathode character display. I have plenty of experience experimenting with manufactured IN-12 tubes and the power supplies that drive these, but I want to step further to experiment in making my own.
What grade of materials / tubing / valves should I be looking at to try and build my own jig for evacuating air from a tube and populating a gas? I don't suppose just about any valve with do (like liquid control valve) and looking at my hobbyist grade vacuum chamber, the tubing contains a spooled wire on the inside to provide rigidity to counter the vacuum forces. Would brass / copper tubing sealed with aluminum weld be suitable? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
