This week was incredibly important - we might have passed the Armstrong limit, which is the pressure where moisture on the surface of the skin phase transitions to a gas, but we also think there is something wrong with our rig, as it currently reads that we are only getting to about 2.5 psia, but the Armstrong limit is about 0.9 psia. The other possibility is that there is a leak in our system that only kicks in at low pressures, and the expanding gas is the cooling effect I’m feeling, meaning we aren’t passing the Armstrong limit. I we are hunting down some obscure fittings to go back to NPT from the HVAC fittings used on the vac pump. On an test earlier in the week when we hadn’t attached the glove to the wrist gasket yet, I got some pretty rough burst capilaries on the back of my hand, triggering the end of that test. After we attached the glove to the gasket, everything was under tension and we didn’t see that in later tests. Getting into the chamber is still a bit of a pain, we should work on a better solution for the next one. Also, we chatted with another iphone based 3d scanning company - very interesting, not sure it’s going to be a fit yet, but might be at scale. Playing around with different potential names for the company. I like the idea of something in old latin, ideally related to protection or chainmail, but we haven’t found the right one yet.
