I experimented making lightening and radiation detectors with various neon bulbs several years ago. I biased the bulbs to just below the strike voltage, using them essentially as "miller effect" detectors. Worked.

Re: Hello From Wichita, KS
welcome Doc Joe. I live a couple hours south of you in Oklahoma. It might be nice to meet sometime. I have many interests and lots of stuff, which I tend to share freely with other experimenters. There are some pictures of some of my early fusion experiments on the fusor forum, or you can friend me ...

Re: reactance slide rule
That is a twin to the one I have in my desk drawer. It and around 19 other sliding nomagraphs have been my constant companions throughout my career.

Re: Papp engine demonstration.
This video does a better job on the explanation and you can see the pieces a little better.

I've read about this for years, but never built one to see what it's doing past the expansion/contraction of the inert gas.

Re: Messy bench
It's kind of funny the comments people make about "old test equipment." Especially the kids I work with. My retort is "Test equipment will always do the job it was designed to do." Besides, much of that old stuff wasn't old when I acquired it.

Re: Messy bench
I want to enter too! Here's five of my work spaces.
Garage bench east. Garage bench north. Ham station. Electronics bench Audio bench, littered with robots.
I didn't want you to win hands down without a little competition.

Re: RF driver for drift-tube accelerator
Seems like you'd be better off in the long run to run a balanced output rather than to ground one drift tube. The matching is no more trouble than matching to a coax and you will have less loss due to heating in the transfer cabling. The termination impedance of your drift tubes will doubtless be ...

Re: Carl G's fusor and team
That's good stuff! Carl does a reasonable job of conveying science to a journalist as well. Kudos to Carl, keep the faith brother. My only question, (warning! warped humor) and this because I'm tall. Why'd you put the controls down next to the floor!

Re: Tube circuit design as art
I have never seen a 6KD6 amplifier so they truel7y may be better. The amps I worked on in the middle 70s were the commercially made CB amps, marketed of course as "ham" amps. They were built as cheaply as possible and sold for more than they were worth. I have ham transceivers that use sweep tubes ...
