Re: No Intranets and no songs??

Be specific, Frank. Tell us exactly how. Go follow those links that you mention. I tried and what I found got the site's version of a 404 error. Here's what I did. Top -- fusor.net page. Umm. no such links near the bottom. Where would they be? Try 'Best of Fusor.net' Strange page but scrolling down,...

Re: Development of HV smps

Unfortunately Silviu seems to be one of the members who lost all of their attachments. So the post about a power supply design project, that Cai provided a link to, is missing all of the pictures of the work that Silviu posted.

Re: Magnetically assisted ionization

Joe joined the forum about a year ago and dived right in with his plans for a well thought out small fusor design. He very quickly built it and had success. Jon has followed up using a very similar design, starting about mid last year. After Joe began to do fusion and shared his results over a few m...

Re: Magnetically assisted ionization

Re: Magnets in Joe Gayo's design. Jon Rosenstiel's cube fusor is basically the same design and he has had direct contact and conversations with Joe. I had never heard anything about the effect from the magnets so I asked Jon about it in his thread in Nov. https://fusor.net/board/viewtopic.php?f=6&t=...

Re: Power Supply from an "interesting" XRT

Rich, The voltages across the diodes in this center-tapped full wave circuit is something you pointed out to me in an earlier thread. The full end-to-end voltage requirement is something I missed after dozens of years of looking at that circuit configuration. It is important and many, like me, might...

Re: Fusor.net Picture Archive 2000 to 2013

Frank, Thanks for the description. Not surprising, I guess, that all the files got dated 2013 when they were saved during that move. How those dates got changed to 11/2019 is a mystery, but since they all began with 2013 dates, neither version would help matching up the files to a message where they...

Re: Fusor.net Picture Archive 2000 to 2013

Frank, I downloaded the zip and expanded it. Lots of nice pics in there. I recognize a few that go to an old thread that I learned a lot from. (Images now holes in that post.) Haven't tried to fix it yet. I suspect that my previously described method might help to match many up. Looking at the downl...
