Default Re: Testing under vacuum

energy is small if you measure it in small amounts

you could for instance fill a bucket full of energy and measure that
the other great hangup I have for any block testing is no lab chiller
you cant measure a difference if you don't know where your starting from
measuring on the "fly" isnt as easy as measuring in larger volumes, you can always do a good job of insulationg
and you can workup an error correction as well

http://www.robertsoxygen.com/htmlfiles/VJ%20PIPE.html (can be had in flex too, dozens of manufacturers)
pump into a dewars container with a known rate of loss

the monday following Easter someone made an error and stuffed a NesLab HX-150 in the wrong spot on ebay, that combined with it more or less being a holiday led to a $5000 list (and it looked new) recirculating lab chiller going for some $350

of course shipping 320 lbs halfway across the country was how I got outbid by $5 in literally the last second (I hope that was you )
which brings me to ebay notifying me of an end to an auction one day after it closed
a tested and functional HP 6050A mainframe didn't sell with $49 starting bid

but its all good, Im feeling much better now and have time to fix the holes in my wall
I landed this

I'm playing around with the software, memorizing the manual and counting the days till it arrives, Im also seriously pimping for 20 or thirty cases to review, I need to stop spending money and start making it, need another specific DMM (HP 34401A) so I can use the software I have for my Autotest UTS-325

oh an Kyle shitcanned me
but W1zzard picked me up in a heartbeat
need to change the name of the lab
