Hey, just wondering what your electric set up was with this, regarding the set up for a MOT instead of a NST, as I am looking to build one of these myself and find that I have a couple of MOT's in my possession. Thanks in advance.
@EgoSumVerum This is a way old video, I don't even use mot's or nst's anymore, but due to a safety concern, I wouldnt suggest a mot, if you do use one, just ground the core of the mot and connect the hot wire to the feedthrough. You could use afew mots with their secondaries in series connected to a voltage multiplication scheme to get actual fusion voltages but they will start burning out if you use more than 3. Goodluck, be safe and don't sue me!
Not that I have any desire to publicly discredit someone I know and from my own community, however, I'm sorry to say he's mistaken. Hearing that name is enough for me, I don't even need to read the post. You can run a Fusor with or without a ballast. Ballasts are just helpful at times, refer to my previous post for details. Let that be the end of it.
@U235hexafluoridedude fusor.net/board/download_thread.php?bn=fusor_hvpower&thread=1297652125 let me hear what you think about conrad farnsworth's post saying it cant be done. make sure you include the Hyper Text Transfer Protocol with the :// and the WorldWideWeb with a dot. for acronym of hyper text transfer protocol, it is the combination of evey letter in caps (in Hyper Text Transfer Protocol) followed by :// otherwise it wont work.i did that because w/the full url i could not post thanks
@u235hexafluoridedude on fusor.net someone said that the demo fusor will only work with with an unballasted neon sign transformer but someone on youtube (clagwell) ran a small demo fusor with a ballasted 9kv neon sign transformer. Do you need an unballasted transformer or not. I ask you as the people on fusor.net have not activated my account and there is only one post about this saying you can't and that is it, no other info and I can't ask anyone there obvoiusly thank you for your time
@Xu53r1X There's no reason why a ballasted PSU won't work, my current 70,000 volt multiplier is ballasted, if it was not it'd supply well over 10,000 watts, whereas limited I'm getting a comfortable 300 watts of available power. To be honest, it's generally best to have some form of current limit on your power supply or else you won't have very good control of the system. Link the fusor forums post so I can read it.
@U235hexafluoridedude so with a neon sign transformer i would follow: wall outlet --> variac --> neon sign transformer--> negative to inner grid and outer grid soldered to chamber--> chamber to ground? Or would i have to do this: wall outlet --> variac --> neon sign transformer--> rectifier diode on negative --> negative to inner grid and outer grid soldered to chamber--> chamber to ground? thanks in advance
@U235hexafluoridedude unrectified? do you mean it was unrectified from the start and tell me if this is the setup you used wall outlet --> variac --> neon sign transformer--> negative to inner grid and outer grid soldered to chamber--> chamber to ground?
@Xu53r1X yes, but on this old fusor is was a MOT not a NST, and there was no negative, just AC. The fusor is a giant hot cathode vacuum tube rectifier, it's going to rectify itself in the end.

@U235hexafluoridedude
Thanks for your help, and don't worry, I admire your work on these machines far too much to even contemplate suing you :)

A simple resistive or inductive ballast will simply limit the current, even in an arc.

@u235hexafluoridedude but if the demo fusor arcs won't the ballast turn it off?

@Xu53r1X Your question has already been answered, I'm afraid you need to figure it out.

unrectified? hmm i will use my mot on mine then didnt knw it would work with ac current
