Re: How would you go about stepping up dc power supply volta

... ratting and upping its voltage as Rex & Garrett both point out. Just remember, when you open the supply in that manner you are on your own - safety is a very important issue and when the system is at a higher voltage it is now well outside its safe operating parameters and you alone must ...

Re: How would you go about stepping up dc power supply volta

... of the kind of modifications I have described here wouldn't be easy and shouldn't be attempted by anyone who lacks good engineering skills or HV safety concepts. So -- maybe. But not easily if at all.

Thin-Walled Acrylic Demo Fusor

... as a testimony to the strength of acrylic (even at 5mm thickness) for simple cheap vacuum chamber setups :) Of course, this is bordering on the safety of vacuum chamber design. I wouldn't advise to go any lower in wall thickness. Acrylic splits clean when it fractures, but if you use glass, ...

Re: The Beginnings of a Fusor Electrical System

... configuration. AC voltages can start to become deadly very fast. Air grounding occurs quickly and then makes these voltages deadly. Follow HV safety procedures (i.e. one rule is: always assume any source is hot and deadly until proven otherwise!)

... field launching corona which causes ozone which when you get enough will easily jump a distance much further than what is there. It is also a safety item and should be indestructilbe and if it overheats and goes open cicuit must not arc over the damaged section.

Re: John Beutz Fusor... The Story so Far

I have stressed electrical safety but one needs to be aware that over 35 kV fusor operation x-rays start to be significant; this radiation is an extremely dangerous component of a fusor; that is, fusor walls start to become transparent ...

Re: John Beutz Fusor... The Story so Far

A very good ballast resister is needed that will not flash over under short circuit conditions

this for safety yours and your electronics (diodes metering etc)

Re: John Beutz Fusor... The Story so Far

... both reading up on these units and understanding high voltage systems in general before ever applying voltage to that 100 kV x-former; first, for safety reasons but also, if you burn out that x-former, or design/install the wrong type of supply voltage to it, you will not succeed and may have ...

Re: John Beutz Fusor... The Story so Far

... those voltages can be. Diodes for those voltages and currents are rare and expensive. One does not want to blow those so care is not just about safety. Cables and connectors are extremely hard to find and new ones are extremely expensive but you absolutely MUST use properly rated cables when ...

Re: Mech Pump and Transformer Questions

... places I would touch before doing so until I confirmed the integrity of my design/system when the x-former was hot. Speaking of fusor electrical safety, your list should include confirming that you have a good ground point to build your various power systems around.
