Re: My Visit w Doug Coulter

Well, thanks for the encouragement, and of course, the insights you've shared - many of which were "just" intuition at the time, but which I've since actually measured and proved to be correct! And oh, your habit of hooking up at least one counter to an audio output might have saved my life. I still...

Re: My Visit w Doug Coulter

Pretty much what I read above is correct, FWIW. As John and Bob say, there's more on my site. Which is why you don't see me here that much - I'm busy with my own. Thanks to Bill for the head's up here. He's been kind of a silent (to the world) partner and big contributor to the effort. What I'm tryi...

Re: Archived - OP position progress

Jason, I use my real name (and the silly profile picture) on G+ and am on most evenings EST if you'd like to chat. We can move to other comm as required for security. After that Vice video I've had to be real careful about handing out my email in public - trolls come out of the woodwork. I don't get...

Re: Archived - OP position progress

Thanks, Dennis, I'm lucky to have the time and other resources, so why not max out the fun - with safety? Not all luck, of course, I worked long and hard to get here. Richard is pretty much on target here (doh, as if that were news) - many dream, few do. And of the latter, few can. But what is true ...

Re: OP position progress

Well, even if I wasn't a bit of a luddite about some things (and I surely am), there's also this fact that I'm totally off the grid (solar), and the clock runs a year on an AAA battery and is always-on. The computers, not so much. I hope you can get what you need out of LabView. It didn't look like ...

Archived - OP position progress

Making some progress on the remote operating position for my fusor. Another computer yet to hook up, and a few other details at this end, like the panel hardwired to power relays at the fusor end for "stop this now no matter what" kind of control, but this looks like a fun cockpit to fly it from, eh...

Re: Grid Design

Hi Rich. Actually, PaulS fixed it for me to retain continuity (Thanks, Paul). Yes, I'm still working on fusors, but not actively running just now as it got to the point where the flux was dangerous, so I've taken roughly the last year to set up automation (and build a new building to operate from), ...

Re: Grid Design

Some more on how I do it on this play list: https://www.youtube.com/playlist?list=PLqWoXk95hIGMYHDAedWeQytwIrmY3JsFv I've since found that with precise, slightly under-size hole drilling, I can skip any adhesive. You just have to be careful putting it together as a push fit, and make sure to deburr ...

Re: Greg Courville Neutron Club entry Feb 2016

Congrats! Nice work! You'd be welcome in my lab anytime. Having been about where you are - I'll warn you that a little down the road (should you continue) with higher voltages and a need for lower pressure so as to limit current to something not-insane, you're going to need something like a current ...

Re: My Visit w Doug Coulter

Thanks, Frank - we indeed had a problem with power supply energy X ray shine through - one we nearly eliminated via the lead coating of everything - perhaps surprisingly, we even had to do some of the vacuum plumbing. At least at those energies (50kv nominal here, probably more with some inductive k...
