06:03 <pie_> pointfree, welcome \o/

17:33 <pointfree> o/ pie_ !

17:45 <pie_> random find scrolling through things tagged semiconductor on githb https://github.com/exa-mining/formal-verification-vlsi

17:46 <pie_> (its just a list of stuff)

17:46 <john_cephalopoda> Nice. We should have a page for material collection on the wiki

17:47 <john_cephalopoda> I'll set one up after dinner.

17:47 <Noxz> stabalizer legs came up in an off-topic chat (people working for semiconductor places) .. looked into the newport ones some

17:47 <Noxz> will absolutely need to figure out something for my SEM

17:47 <Noxz> also, one week of watchmaking school completed!

17:48 <Noxz> super tired already, trying to get into the rhythm

17:48 <john_cephalopoda> Noxz: Stabilizer legs for what exactly?

17:49 <Noxz> SEM

17:50 <Noxz> lots of road vibrations

17:51 <Noxz> live kinda near/under a bridge

17:51 <pie_> oh cool @ watch school :p

17:51 <Noxz> :D

17:51 <Noxz> 2 projects completed already

17:51 <Noxz> some parallelagram wood block thing, and our name plate

17:51 <pie_> meh, if a deer walked by that would be too much vibration :PP

17:51 <Noxz> amazing we get to work with tools on the first day

17:51 <Noxz> lol @ deer

17:51 <pie_> you do? xD

17:52 <Noxz> yeah, other schools are like 6mo of theory and calculations and such

17:52 <Noxz> but we start immedietly

17:52 <Noxz> exactly what I wanted

17:52 <pie_> are you overqualified :P

17:53 <Noxz> there's only 5 first year students.. only one guy is really over most of the others

17:53 <Noxz> but, not sure how much watch mfging he has done, I dont think much

17:53 <Noxz> just more so practice in other trades

17:54 <Noxz> knife making, scroll work, etc

17:54 <Noxz> one guy straight out of high school, like 19 years old

17:54 <Noxz> that other guy has a daughter older than that :P

17:54 <Noxz> oh, also that 19yo knows about sci-hub

17:54 <Noxz> which was super cool

17:55 <pie_> hehe

17:55 <pie_> we arrrr pirates

17:55 <pie_> (well im a couple years over 19 now..._

17:55 <Noxz> a decade and some change for me

17:55 <pie_> random possibly interesting social science project?: prevalence of scihub knowledge by age

17:56 <Noxz> anywho, now that I have my first weekend off, and not doing house work.. trying to work on the biodiesel engine/flowbench/ECU

17:59 <pie_> i need to finish cleaning my room one of these days so i can get to my electronics table and maybe actually play with some of that stuff..

18:28 <pointfree> Noxz: Have you looked into sorbothane mats? https://www.amazon.com/Isolate-Sorbothane-Vibration-Isolation-Square/dp/B0042U78H2/ https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=6421

18:28 <pointfree> It would be interesting to know how they compare to stabilizer legs.

18:29 <Noxz> I have some neoprene sheets I was going to experiment w/.. for thickness and durometer for what sound it blocks..

18:30 <Noxz> I wouldnt have much confidence in the life span of those mats

18:30 <Noxz> good for the first week, then the machine legs would settle in

18:30 <Noxz> pushing all the air out

18:31 <Noxz> not sure if true or not, but likely?

18:42 <pointfree> good point on the lifespan.

18:42 <pointfree> "Sorbothane®absorbs shock efficiently for millions of cycles." https://www.sorbothane.com/Data/Sites/31/pdfs/product-guides/Sorbothane-SPG.pdf ...that's all I found so far on that.

18:43 <Noxz> it looks ridiculously low budget though - not for scientific equipment, more for audio and machine shops

18:51 <qu1j0t3> constant weight is a very different matter than transient shocks?

19:04 <john_cephalopoda> Noxz: At the student science lab at my old school, they have an atomic force microscope. Because even footsteps would bring problems, they mounted a hook on the ceiling, hung heavy stones from there and put the microscope into a box on top of the stones.

19:05 <Noxz> I have seen springs used as well, from the cieling

19:06 <john_cephalopoda> Maybe a combination of springs and weight could weaken the connection to the outer world and reduce the effects of an impulse.
