Re: DIY Turbopump Controller
Jerry, I guess you posted the scans of the NT50 controller a few years back as I have a saved copy. (Not sure if the post was here or Coulter.) Anyway, I took your separate page scans and merged the ones that make up just the schematic in to one single big PNG file. There are other pages in your sca...

Re: Beam on Target Project (BOT 2021)
Very nice work, Mark. What metal did you use for your cube?

Richard's argon wall
HEAS 2020 looks really great from all the excellent shared pics. One of Frank's pics shows Richard's argon wall. From the pic, I assume this is mainly for entertainment. Looks fascinating. Similar to a flattened plasma ball? Richard, for those of us who didn't make it to HEAS 2020, can you describe ...

Re: 50kV Supply
Nicolas, Per your, "opening up my Glassman 50KV supply." I'm not sure what that means. What exactly do you have? The aluminum box that Joe tipped us off to is part of a rearranged custom design based on a Glassman ER50N6 0-50kV 0-6mA supply. That aluminum box has the high frequency transformer and a...

Re: Looking for a cheap dual stage vacuum pump
Cade, Don't know if it will help, but I suggest you edit your profile and add a Location to your info. Doesn't have to be precise but, like mine, your city might help a lot. Shipping for large heavy things like a vacuum pump is a PITA. Just maybe you'd get a response from someone if they knew it was...

Re: Comet NEOWISE
Yes. Checked it out last two nights. Best I've seen since the two big ones in mid 90's. Shared it with a couple of neighbors. Tried to check it out a week or so back in pre-dawn but no luck. Thursday night tried again but this time in early night just after skies darkening, around 9:30 PM. Success w...

Re: Edit posts
Frank, I just found one of my old posts that has the inline attachment issue. Filename is there and opens the image if clicked on but the thumbnail doesn't show in the message.

Re: Edit posts
Frank said, "The photos of those with the ID numbers starting with a 4 are gone according to Rex." Not quite right, I wish it was just 4. It is 4 or greater. From what I see in posts, the users who lost all their uploaded files in the move are users who's ID number begins with the number 4 or more (...

Re: Edit posts
Tyler, Good work. Thanks. Frank, Re: "Let see the others in the thread can do theirs too. Rex, Rich and Rich?" I assume by that you mean me, Rich Feldman, and Rich Normand. None of us three are suffering from the post-move global attachment loss syndrome. But there's another weird glitch that happen...

Re: Ludlum model 3 issues
Sarmad, None of that explanation makes any sense to me. There's no 64W pot in a Ludlum 3. The batteries probably couldn't supply 64W if they were shorted. The little pot for HV adjust setting is probably 100K ohm. In the circuit it should draw microamps and micro watts. Not sure how you were measuri...
