Re: High Voltage Ballast Resistor and Inner Grid Help

Yes to referencing the grid, and I should have said tungsten - good catch.

Re: High Voltage Ballast Resistor and Inner Grid Help

I got a fusor grade 300 watt wire wound ceramic resistor on e-bay. If one searches often, a usable unit often appears - don't be too specific and get a large number of hits to look over. Remember, they can be put in oil to improve their cooling so a lower wattage resistor can be then made acceptable...

Re: Hello from Ohio

Welcome. Do read the information sections on the required components that any real fusor requires. Without proper knowledge of all the detailed parts/assemblies needed by a fusor, one is wasting their money and time trying to collect useless (maybe) parts or building devices that will not work for f...

Re: Removing Turbo Pump Rotor

If you think it is "gummed up" then try cleaning it. Acetone is often recommended for some turbo's. Then a rinse with absolute (or close) alcohol. If it is the upper "floating" bearing, then you are done. If it is a lower bearing, then one needs turbo pump bearing oil to re-lubricate the bearing. Do...

Re: Seeking Advice

Achieving fusion is not easy and cannot be done cheaply unless one can really use ebay so they get very good deals (i.e. catch items others miss and/or can fix stuff others won't buy because the items don't work), and one can basically build very complex electronics themselves - detecting neutrons i...

Re: High Vacuum Engineering Design, Analysis, and Build of a Small-Scale Multipurpose System

When you say: Additional high and ultra-high vacuum pumps can also be employed, such as ion pumps and titanium sublimation pumps with relative ease and low cost These are very expensive items new, and not very easy to obtained used; and more often, not in the best condition when used (especially the...

Re: Hello

Hello and welcome.
Might be a useful post to discus both what you have done to date on your fusor project and your plans for the various parts to get it completed. Post in the New User Chat section. This will be useful for everyone.

Re: The Beginnings of a Fusor Electrical System

Looked it up and it is based on a plasma and called an AC-DC transformer for his first and only successful (i.e. built) design that is listed. Now he has speculated on magnetic re-connection relative to a DC-DC (but still uses induction and hence has to have a time varying component) but that requir...

Re: Greetings from Illinois

Hello. Note that there is a wealth of information located for each forum section related to FAQ's and well worth reading all those that interest you. Reading these will help one in getting a good idea on both the simple concepts and practical devices used in fusors.
