Re: Fusor CAD models

<r>> Okay, I know this is starting to sound like an advertisement now, but the point being, if you are going to try to make a CAD model of your fusor, use Inventor.

Re: A Few Questions Reguarding a Spellman XLF Power Supply

<t>> I am wondering if it is a time that the Perfesser needs to be adding in some prominent legalese flags with specific limitations of liability both for himself and all who contribute.<br/> <br/> I have been told in the past that if there is a pond on my<br/> property, and I put up a 20 foot high ...

Re: Problem.

<t>> idea was to use a neutron counter coupled to a 555 [ trigger input ] and to have it battery operated - the output driving an LED. The device could be built in a simple metal pipe so it would be completely shielded. The output would be optic from such a completely sealed unit and with no wire ca...
