(I put it in negative color to hide the mess in the background... if you really want to see the horrible side of things, you can revert it...)As promised, the vacuum gauge controller. This one handles readings from 1 atm down to 1.0e-12 torr. In comparison, pressure at the Kármán line (100km above sea level) is only 7.52e-3 torr. I originally felt that it was overkill to buy such a nice piece of equipment - but it seemed like the only one which offered portability between two thermocouple gauges (readings in analog on the two leftmost dials), and an ionization gauge (reading in digital in the centre dial), which fitted with my needs exactly.
It came with plenty of styrofoam underneath. Collar pin from local science and engineering fair to show the size. (There was a lot of styrofoam, so I was finding a needle in the haystack when I accidentally dropped the collar pin into the styrofoam pile.)I switched off my computer and removed my 850W psu 3-pin cable to see if it fitted. Voila. Only thing is that my CPU power supply probably has a higher fuse rating - the controller runs at 200W - no problem, I'll just take out one of my monitor power cables. The controller was factory set at 98-132 VAC, 60 Hz... my team mate will come over tomorrow to help with dismantling it to switch it to 230 VAC, 60 Hz on our power grid; and make sure everything is working fine. Guess it's a better idea to have a second person while doing this - can't afford to replace this part.
