Re: FAQ - Analog metering of High voltage supplies.

A lot of good info and ideas here. For someone not very experienced with electronics, the last diagram has a neon light (if memory serves, these turn on at about 70 volts?) But what voltage diodes would be appropriate in that circuit? I have a 45 kV probe style meter (it can read up to 55 kV.) I hav...

Re: Fusor V construction - the process long running

So very sorry to hear how extensive the damage was and possibly via cross talk along grounding wires?! While I have used seperate grounds (differnt wall outlet circuits rather than a star) for my fusor vs. my detectors, never supected that a star system could kill a turbo controller. When I get the ...

Re: Nathan Marshall - Fusor Progress

Thank you for taking the time/effort to provide the circuit diagram. I was wondering, what are the current/voltage values for the ZVS power supply diodes? Also, what is the current out put/rating of the ZVS supply x-formers? You know, if you keep up these excellent posts, despite my very sore back/a...

Re: Nathan Marshall - Fusor Progress

Can't tell you how impressed I am with your home-built power supply. That is really an excellent, quality build. Your total power (under a 100 watts) is on the low side so you will need a good detector system. However, using your smaller volume fusor (higher pressure deuterium), that power should, a...

Re: Coronavirus pandemic

The corona virus is a simple example of our impact upon the world; certainly that illness is mainly due to the growing population - destruction of habitat for space to grow food and create housing, as well as requirements for new protien sources by said growing populations - all have been the primar...

Re: Coronavirus pandemic

Yes, batteries are the bane of solar (big time) and wind (to a lesser extent.) As for cars, yes, that is just one of its issues; lack of a clean power source is, as you point out, the big one. Fission power is also fully dependent on coal/gas to create its facility and all its fuel, too. But that do...

Re: Fusor V construction - the process long running

Sorry to hear about the turbo - that is just really not fair; as I posted in another thread about turbo vs. DP I'm even more glad I used a DP instead of my turbo for orginal fusor operation. Never suspected that would occur to a turbo but obviously, it does. While I used the trubo only for my deuter...

Re: Jim Kovalchick -My attempt at smaller fusor

As for maybe the same arc issues - that might or might not be the case if I continue to shrink my anode: while it would seem likely if I continued along that path, my results didn't appear to require that to achieve the same pressure increase as seen in small fusors. My anode cage was much larger th...

Re: Jim Kovalchick -My attempt at smaller fusor

First, very good work on your fusor, Jim. Sorry to hear, Richard but the issues with 'real' small fusors, apparently, can be difficult but that has made Jim's work both rather original and interesting. This work by Jim makes me think I should re-explore creating a small fusor via my first and rather...

Re: Andrew Seltzman

While conflat are superior for high vac, I don't see any advantage for most fusors - 10^-6 torr isn't needed so, not clear what is superior for that type flange over standard, and cheaper (usually) KF adapters. I have had great results using KF's since going down to mid 10^-5 torr is more than enoug...
