Re: Comet NEOWISE

I finally got to see it. Haze was not so bad tonight, no clouds and after letting my eyes dark adapt for a half hour I was able to see it through binoculars no problem. It's barely a naked eye object at this point.

Re: NEW Fusor V build under way.

Maybe your old posts got lost in the crash, but I remember with Fusor IV that you got much better results when you were not so stingy with the D2

Re: Comet NEOWISE

I've been clouded out the last two nights. Tonight might be a chance if the scattered clouds move out of the way by the end of nautical twilight here.

Re: NEW Fusor V build under way.

I'm able to go to 60 KV on my system, once I put a one inch ball for the HV terminal with no corona or arcing. But the big difference in my setup is that the chamber sits on a piece of sheet metal with a hole just big enough for the ceramic to go through. So the grounded surface that the HV sees is ...

Re: Comet NEOWISE

I tried looking for it right at the end of nautical twilight Saturday night. Sky in my area was too hazy, could just make out the big dipper once my eyes had dark adapted. If the forecast looks good for Sunday night, I might drive to a site just north of Ricketts Glen, which has fairly dark skies an...

Re: NEW Fusor V build under way.

Ah so you decided to replace the moderator for the neutron detector with a different type. Yes, in that case it's recalibrate from square one. I never had a problem with arc overs killing the turbo controller. My two failures both happened while the high voltage was totally off and capacitance all d...

Re: NEW Fusor V build under way.

I'm still not sure why you can't use your former calibration of the neutron detection system. As long as you have recorded the exact distance the detector was from the center of Fusor IV, you can either place the detector at the same distance or use the inverse square law to calculate what you will ...

Re: Research facility construction

I've used those "Amish sheds" for radio site buildings. If you specify a residential type double door, they will be rodent proof, providing you send the $$ on proper entry bushings for antenna cables.

Re: Research facility construction

You still have that area above the door to get enclosed, as wind driven rain will still get inside at this point.

Re: Research facility construction

Unless Nick figures out how to replicate Doug's "Gonzo" mode and will need a lot of neutron shielding.
