02:08 < nmz787_> anyone have any good links for existing DIY micromanipulator projects?
02:08 < nmz787_> fenn: ^ ?
02:08 < nmz787_> a few months ago I was thinking a few of these might be useful https://www.aliexpress.com/item/32790147861.html
02:09 < nmz787_> but I never splurged, so I don't actually have any on hand to try experiments, or mock-ups... looking at the pics now, I'm not sure I'd be able to cobble a few of them together in a terribly useful manner

03:48 < fenn> i wonder how practical it would be to use one of those flexure nanopositioners in reverse, to amplify the movement from a hunk of piezo material

07:52 < nsh> <gkwhc> Hey guys, I'd like to DIY a fume hood for a small campervan stovetop. Im not quite familiar with the concept of pressure vs airflow volumes. should an axial or centrifugal fan be used? the setup resembles the left most image from https://bit.ly/2XObg8y
07:52 < nsh> -##physics
07:52 < nsh> sounds up the street of some people here
08:03 < fenn> yes he did a drive-by in ##engineering as well
08:04 < fenn> axial for high flow, centrifugal for high pressure
08:05 < fenn> in practice they use axial fans

10:08 < nmz787_> fenn: that 3d printed lever thing is pretty cool.
10:09 < fenn> i failed to find the physik instrumente thing because the WWW is crap now
10:09 < fenn> cryopreserve me now :\
