Homemade cathode ray tubes


[dylan] tipped us to [Nyle Steiner] who’s been making his own cathode ray tubes Not satisified with that, he made an even smaller one and he built an oscilloscope.

Once I noticed that he’s an amateur radio operator, I started digging around his site. His propane lawnmower is a great idea, his diy photocell makes me think of mr. wizard. If you dig tube amps, you’ll definitely be interested in his vaccum tube building experiments.
