High Vacuum

<t>In reference to Implosion problems, Just remember that high vacuum is only about 14.7 psi relative to sea level., I find it funny when safety is replaced with a glass jar not rated for vacuum. <br/> In your system Colin you say ...

Solid state relays for driving pump & valves?

... experiment, and the microcontroller already supports the sort of safety features needed for industrial controls (like single pin forces all the outputs low for shutdown, etc.) For the vacuum system I want to recreate a system I once helped build that logged everything, ...

Re: glassman hv supply

<t>One more safety note - if you let everything float in your fusor setup in order to use a positive ... unless you want the cylinder and regulator to float to HV. The same goes for the vacuum connections. I refused to bid on a perfectly servicable 70kV Glassman supply for ...

Re: Vacuum Chamber Cleaning

... are pretty nasty solvents.. you should used them with plenty of fresh air.. and not flames hot stuff or sparks within a "country mile" for general safety.<br/> <br/> Since you have a closed container.. it should be possible to fill it half full with the solvent and let it stand for a while.. shake ...
