12:23 AM XXCoder: veegee: does bluing stop metalk from rusting?
12:33 AM veegee: XXCoder I don't know much about it. As far as I know, it helps, but doesn't fully prevent
12:33 AM veegee: but it helps a lot
12:33 AM XXCoder: interesting
12:33 AM XXCoder: https://youtu.be/tOVB9I4s0Cs
12:33 AM XXCoder: this guy uses bluing a lot
12:34 AM veegee: I'll check it out
12:34 AM XXCoder: pretty good. he dont use bondo a lot like some "restore" channels
12:34 AM XXCoder: and yeah hes machinist too, he sometimes makes replacement parts when its too bad
12:55 AM XXCoder: yo
03:01 AM p0g0: XXCoder, the bluing I've used is a lacquer and dye. There is another kind, used on guns and such that is an fe3 oxidation layer, and that makes fe2 (red rust) into a more persistent surface.
03:02 AM Deejay: moin
03:02 AM XXCoder: fe3 basically is stronger type of oxide so rust dont form on it? or in least more resistant?
03:02 AM p0g0: well, it is in fact a rust.
03:03 AM p0g0: but it is a resistant one
03:03 AM p0g0: fe2 -> fe3
03:03 AM XXCoder: interesting
03:04 AM p0g0: bare metal, fe oxidizes to fe2, what you think of as corrosion and rust.
03:04 AM p0g0: phosphoric acid (naval jelly, coco cola will reduce the oxides back to fe.
03:05 AM p0g0: *cola)
03:05 AM p0g0: I guess that is Coca Cola (tm)... not something I imbibe.
03:07 AM p0g0: Layout bluing, the blue stuff you lay on a metal to scribe and do layout, is not at all the same stuff.
03:07 AM XXCoder: i know lol
03:07 AM XXCoder: i have used blue bunch of times
03:08 AM p0g0: I had to assume you have, but I wasn't sure if you'd thought it was some kind of rust remover/preventative.
03:09 AM XXCoder: ya blue is way too frigile for that ;)
03:09 AM XXCoder: bluing is very different
03:09 AM p0g0: yep
03:09 AM XXCoder: nbut since we never use that I was wondering on what its properies was
03:09 AM p0g0: it's a "pickling"
03:10 AM p0g0: If you know any decent jewelers that make stuff, they have all manners of nifty pickling cocktails for different metals.
03:10 AM XXCoder: fun :)
03:11 AM p0g0: Pickling and heating can make handsome dichroic surfaces (butterfly wing stuff).
03:11 AM XXCoder: heard lasers can do it also
03:11 AM XXCoder: to specific colors
03:11 AM p0g0: sure, these days, the meta-materials crowd kind of own the game.
03:12 AM p0g0: they tend to be very fragile surfaces tho.
03:12 AM p0g0: Fe3 is hard and persistent.
03:13 AM p0g0: Black polishing rouge is usually fe3.
03:18 AM p0g0: XXCoder, hey, re laserweb- I looked at it a bit, it won't run on AMD64 stuff, right? And if I buy a Pi, does that offer an HTML server and do all the nifty things- I'm learning on a Maslow hanging router, so all I want is better GCode, not anything about motor control etc.
03:19 AM XXCoder: rpi4 yeah thats where i run laserweb
03:19 AM XXCoder: i dont know if laserweb is best ever
03:19 AM XXCoder: but its convient
03:19 AM p0g0: OK, and that accepts an SVG, and some basis for depth & passes to make a 3 axis GCode?
03:20 AM XXCoder: svg yeah just make sure its all PATH
03:20 AM XXCoder: also simpify if it have lots or dots or it will slow down
03:20 AM p0g0: yeah. That lesson is well branded on my lobes.
03:20 AM XXCoder: laserweb dont seem to use g2 and g3 at all so curves is expensive
03:21 AM XXCoder: maybe use inkscape own cam to make gcode for it
03:21 AM p0g0: ah, curves are the better part of the Maslow- it is slow so straight lines are better done on a saw, if you can.
03:22 AM p0g0: The inkscake CAM is GCodetools, and while it works, it is abandonedware and has some bits of stupid in it.
03:22 AM p0g0: *Inkscape
03:22 AM XXCoder: might be better with lots of curves
03:22 AM p0g0: OK
03:22 AM XXCoder: expecially if it actually use g2 and g3
03:23 AM p0g0: I believe it does.
03:23 AM p0g0: I could just look, but not just now.
03:23 AM p0g0: Coffee and such.
03:23 AM XXCoder: i dont know if laserweb is best.
03:24 AM p0g0: yeah, that's OK
03:24 AM XXCoder: i wonder if linuxcnc supports grbl
03:24 AM p0g0: best is not a full scale notion.
03:24 AM p0g0: Somethings are better at a particular task, etc.
03:24 AM XXCoder: no linuxcnc and grbl dont work together
03:25 AM XXCoder: grbl supports g2 g3
03:25 AM XXCoder: probably internally using g1 in segements like many crap firmwares do
03:26 AM p0g0: Yeah. Maslow stuff is a grbl derivative I think.
03:26 AM p0g0: It coughs up GRBL in the gcode header, iirc.
03:27 AM p0g0: I should be able to reach some of my codesets from here, mmt plz
03:29 AM p0g0: Well, the GCode that is sent to the AVR firmware is G02, G03 stuff- I'd have to look at the firmware to see what it does with that.
03:31 AM XXCoder: i need to check mine later heh
03:33 AM p0g0: It looks like it directly handles G2/G3 as arcs.
03:34 AM p0g0: Now I need to find the arc function...
03:34 AM XXCoder: cpool
03:36 AM p0g0: It's in Motion.cpp, and it does arcs as trig radii unless the chord length is long, then it swaps into G1 segments.
03:37 AM p0g0: "Large-radius arc replaced by straight line to improve accuracy:"
03:39 AM XXCoder: odd
03:39 AM XXCoder: I guess it dont do steppers control like linuxcnc does
03:39 AM XXCoder: so linuxcnc stays very tight to arcs
03:39 AM XXCoder: fporgot what its called
03:40 AM p0g0: more precisely, it computes the delta from the chord to the radius, and if that is large, it uses G1.
03:40 AM p0g0: the "chord height"
03:42 AM p0g0: Anyway, it handles G2/G3 in the GCode source, and so far, it seems to do a good job of high order curves.
03:43 AM p0g0: Inkscape fonts, beziers, etc (with some caveats about the font itself, TTF vs engraving)
03:43 AM XXCoder: you can convert text to path also
03:44 AM p0g0: yes, that's been fun-the maslow makes very nice signs.
03:44 AM XXCoder: if engraving can leave everything as is then export a png
03:44 AM XXCoder: nice
03:44 AM p0g0: OK. The TTF's are all loops, not a single linear path.
03:45 AM p0g0: Just to offer the Big Distinction.
03:45 AM XXCoder: tried to google maslow its not too clear
03:46 AM p0g0: yeah, you got the shrink as a first hit.
03:46 AM p0g0: "maslow CNC" works better
03:46 AM XXCoder: no i got so many different types of cncs lol
03:46 AM XXCoder: laser cnc router and router
03:46 AM p0g0: it's a hanging router
03:46 AM p0g0: like a hanging plotter
03:46 AM XXCoder: ah the wall type
03:46 AM XXCoder: nice
03:46 AM p0g0: yeah
03:47 AM p0g0: 4' x 8'
03:47 AM XXCoder: how it works out for you
03:48 AM p0g0: I have had good experiences so far- the 8' long runs are pretty close to perfect, and they are reliably repeatable.
03:48 AM XXCoder: wha
03:48 AM XXCoder: 399 bucks for complete kit?
03:48 AM p0g0: I overbuilt mine- it uses a yard arm along the top, I have a 12' arm
03:48 AM p0g0: hmm a bit more, but yeah scary cheap
03:49 AM p0g0: the z axis is not that great, but adequate,
03:49 AM XXCoder: what does i have to buy seperately?
03:49 AM p0g0: It doesn't do all 3 axis at once- the Z steps.
03:50 AM XXCoder: http://maslowcommunitygarden.org/Maslow-kits-for-sale-soon..html
03:50 AM p0g0: the router and the wood to assemble it. The Z axis adds about 50$
03:50 AM XXCoder: 399 bucks. shipped
03:50 AM p0g0: yes, the bay area kit has the Z axis
03:50 AM p0g0: hang on, I'll get the URL.
03:51 AM XXCoder: 550 bucks basically includes everything
03:51 AM XXCoder: not router but has sled and stand
03:51 AM p0g0: https://www.eastbaysource.com/ is the kit I got. I had to get a bit more #25 chain to do the 12' yard arm.
03:52 AM XXCoder: https://www.makermadecnc.com/product/maslow-cnc-ready-to-ship/
03:52 AM p0g0: I also did a 1.5 degree slope, and a 30" above the work area setup.
03:53 AM p0g0: I looked around, the east bay folks won the game for me.
03:54 AM p0g0: It was simple enough to construct and calibrate, but afaict, I got a bit lucky with my calibration, some seem to muck about more that I did.
03:54 AM XXCoder: cool :)
03:54 AM XXCoder: its not bad at all
03:54 AM XXCoder: perfect for large single sheet funtures and such
03:54 AM XXCoder: you know of those?
03:54 AM p0g0: One of the things I have and will use it for is jigs and layout.
03:56 AM p0g0: yes, I have a large wood stock here, I harvest logs, have them milled, and many of the stacks are old and well seasoned. Contrary to most reports, it handles reasonably clear hardwoods well- I expect most folks have to spend a lot more money than I do for their wood, so they lose big when something fails.
03:57 AM XXCoder: i want to make single sheet funture for heck of it :D
03:57 AM XXCoder: I guess hardwoods need lower feed speed
03:57 AM p0g0: So, yeah, plywood and 5/4-3/4 stock is working well enough for me. I am not sure it would meet some folks standards, but it certainly mills and laysout at that scale better than I can.
03:58 AM p0g0: yeah, but the Maslow is slow anyway.
03:58 AM XXCoder: not surpised due to its ropes design
03:58 AM p0g0: It's not a high production thing.
03:58 AM p0g0: chains and gravity, but yeah
03:59 AM p0g0: eh, I said 1.5 slope above, that is a typo- 12.5 !
03:59 AM p0g0: 1.5 would be a big fail....
03:59 AM XXCoder: ah lol
04:04 AM XXCoder: p0g0: wonder if itn could be changed to laser for fun
04:04 AM XXCoder: or was that what youre planning to
04:05 AM XXCoder: it wont cut though wood but interesting
04:32 AM p0g0: no, it could run a laser, but those scare me, so I'll pass on that. It will run a pen tho, if you want a large scale paper plotter.
04:33 AM XXCoder: if i made that type lser machine it wouldnt be cutting strength
04:33 AM XXCoder: engrave only. so maybe 500mw or 1w thats it
04:35 AM p0g0: I am just too timid around lasers like that- now if I was feeling artsy, I might do some paint on photo emulsion and run something very low energy and then "develop" the emulsion.
04:35 AM p0g0: a 4'x8' B&W print kind of thing.
04:35 AM XXCoder: laser film dev interesting
04:35 AM p0g0: easy enough to do too.
04:36 AM XXCoder: i guess it must be very dark while thats being ran
04:36 AM p0g0: well, that depends on the "film speed" of the emulsion- and the ambient light- a maroon/red should be OK
04:37 AM p0g0: But the laser might want to be a higher frequency light.
04:37 AM p0g0: Darkrooms for common silver halides got away with low level red.
04:37 AM XXCoder: im guessing it needs to be very low power
04:38 AM XXCoder: you dont want it burn though
04:38 AM p0g0: The laser would be "very bright" compared to those, even a low power one. Dwell time would also work.
04:39 AM p0g0: You wouldn't even need a laser for that, a bright lamp and pinhole/tube/lens would do.
04:40 AM XXCoder: led for far better control range
04:40 AM XXCoder: expecially if pwm type so you can get really dim led without it turning off
04:41 AM p0g0: Its not an uncommon bit of art to see a wall painted with emulsion, then a long exposure slide projector with a negative to make the image.
04:42 AM p0g0: The rest is just plain old developing/fixing/washing.
04:42 AM p0g0: If you are old enough to have worked in a B&W darkroom, it would be standard stuff.
04:42 AM XXCoder: i wasnt lol my bro went to bw photography class
04:43 AM p0g0: He'd get right on it then.
04:44 AM p0g0: My dad was a "light sensitive compounds" guy, films, photoconductors, etc. I sort of grew up in a darkroom.
04:48 AM p0g0: Stuff like this: https://www.bhphotovideo.com/c/product/45028-REG/Rockland_LLE8_Liquid_Light_Photo_Emulsion.html
04:49 AM XXCoder: interesting!
04:49 AM XXCoder: so it turns into bw photo on anything?
04:49 AM p0g0: yes, more or less.
04:50 AM p0g0: If the surface wicks a lot or such, you might have issues
04:50 AM p0g0: But what you know about paint sort of covers it.
04:50 AM XXCoder: ohh i have an idea
04:51 AM p0g0: It wants to be a uniform top surface.
04:51 AM XXCoder: paint a sphere, and cnc to rotate it around
04:51 AM p0g0: yes.
04:51 AM XXCoder: add laser or led that can focus to a very small dot
04:51 AM XXCoder: heavily protected against scatter
04:52 AM XXCoder: plenty of foam spheres I wonder if can just do primer then some form of paint that can hold that chemical well
04:52 AM p0g0: I had an art teacher that used photo emulsions like that on a silk screen, as a mask- then he'd screen glazes onto ceramics and fire them- 10k year grade images.
04:52 AM XXCoder: interesting
04:53 AM p0g0: It was amazing stuff really, monochrome, but great detail. And that ceramic really could last for thousands of years.
04:53 AM XXCoder: i joked often about people in far future thinking that we worshipped weird shaped symbols
04:53 AM p0g0: You may have encountered images like that on tombstones- it was a thing 100 years back.
04:54 AM XXCoder: almost always while, has a basin that drains into hole
04:54 AM XXCoder: *white
04:54 AM p0g0: One vomits as abeyance or prayer?
04:55 AM p0g0: I suppose
04:55 AM XXCoder: hold on a sec
04:55 AM XXCoder: note i made this joke before i read this book but man you probably would love it
04:56 AM XXCoder: laughed so much while reading it
04:56 AM XXCoder: that is if i can find it
05:05 AM jthornton: morning
05:06 AM XXCoder: hey jt
05:07 AM XXCoder: p0g0: found name
05:07 AM XXCoder: motel of the mysteries
05:07 AM XXCoder: by David Macaulay
05:07 AM XXCoder: its old story so you can download ebook free. its very short read
05:08 AM XXCoder: https://sultanaeducation.org/wp-content/uploads/2014/06/Motel-of-the-Mysteries-Macaulay.pdf
05:08 AM XXCoder: 4 pages
05:08 AM p0g0: XXCoder, Lots of dystopia out there- the old classic is "A Canticle for Leibowitz"
05:09 AM XXCoder: its not dystopia story
05:09 AM XXCoder: 4 pages. with images. you'll love it
05:09 AM p0g0: Ah, A canticle sure is.
05:14 AM XXCoder: dammit its part of it
05:14 AM XXCoder: lemme find complete version
05:18 AM XXCoder: http://onlinecampus.fcps.edu/media2/Social_Studies/WHGII_2010/Era1Topic2/Resources/Motel_of_Mysteries.pdf found it
05:18 AM XXCoder: it has more pictures and are complete. 5 pages anyway
05:21 AM p0g0: I get the idea from the 4 pager. Yeah, we'll make some future archaeologist a good puzzle. I hiked around Tikal Guatemala once- the earth does a first rate job of churning and burying stuff- ceramics are about the best thing for the long term data transmission.
05:22 AM XXCoder: yeah. but man the final image
05:25 AM p0g0: Ma Bell as a percussion instrument...
05:43 AM XXCoder: https://youtu.be/rvc_1PFBpBI amazing idea really
05:43 AM XXCoder: perment display
05:44 AM XXCoder: note earlier video he successfully made good one. this video is where he finally does something to failed one
06:13 AM jymmmm: good morning
06:15 AM XXCoder: hey
06:21 AM jymmmm: They don't know, but speculate corona can live outside a host from hours to days. If so, why the fuck are they telling people NOT to wear masks?! HAve they not heard of cross contamination????
06:22 AM jymmmm: If it's respritory, then touching an object with your hand then touching your face/mouth, could make you infected. At least a mask would prevent you from inadvertanyl touch yur face
06:29 AM XXCoder: jy current research is pretty close now
06:29 AM XXCoder: 3 days
06:29 AM XXCoder: thats for metal and plastic
06:29 AM XXCoder: cardboard 24 hours, copper 4 hours
06:36 AM jymmmm: XXCoder: how about melamine (grocery store cash register) and rubber (credit/debit card keypad)?
06:36 AM jymmmm: and aluminum/brass doorknobs and door pulls
06:36 AM XXCoder: dunno ill just assume 3 days
06:37 AM XXCoder: alum counts as regular metal, while brass dunno since it has copper in it
06:38 AM jymmmm: and you say cardboard, but if a person is infected at amazon warehouse, coughs on your box, it ships to you, you have wet hands, can you get infected? I'm suspecting maybe
06:38 AM XXCoder: 24 hours sure
06:38 AM XXCoder: i just open box expose stuff to air then leave it 3 days and I wash hands very well
06:39 AM XXCoder: thats what I did with wires I ordered from china right before coronavirus thing happened
06:39 AM jymmmm: If already infected, washing hands isn't gonna help, but disposable gloves will
06:39 AM jymmmm: that makes sense XXCoder
06:40 AM XXCoder: virus cant get in though skin
06:40 AM jymmmm: but, you can cross contaminate by touching your face/mouth
06:40 AM XXCoder: hence all that no touchy eyes nose and mouth thing :)
06:41 AM XXCoder: I also dont let box touch anytjing like my desk or stuff
06:41 AM jymmmm: I've been saying this for years
06:41 AM jymmmm: even for the common cold
06:41 AM jymmmm: people don't realize how often they touch their face/mouth
06:41 AM XXCoder: i dont realize how often because I know how often I do lol
06:42 AM XXCoder: if someone in china sneezes cold I get it
06:42 AM XXCoder: just so glad im not as sensive to other stuff lol
06:42 AM jymmmm: yeah
06:42 AM jymmmm: and hand sanitizer is NOT a substiture for soap and water
06:43 AM jymmmm: it's just a stop gap
06:43 AM XXCoder: at wo5rk I just use soap and water till I am ready to go home, then I wash hands then sanitize it and go out without touching anything else
06:45 AM jymmmm: santize your hands how?
06:45 AM XXCoder: hand sanitizer
06:45 AM XXCoder: what else? heh
06:45 AM jymmmm: you do not need alcohol hand santizer if you use soap and water
06:46 AM XXCoder: it was just in case thing
06:46 AM XXCoder: one guy at work constantly use it lol
06:46 AM XXCoder: I mean it
06:47 AM jymmmm: There was a epidemic in a 3rd world country doctros with our borders. they used hand santizer constantly. Hand they just washed their hands it would have killed the infection
06:47 AM jymmmm: had*
06:48 AM jymmmm: Alcohol is just a stop gap until you can wash your hands with soap and water.
06:50 AM jymmmm: XXCoder: Oh, since you asked, 1/4th bleach, 3/4th water in a spray bottle =)
06:50 AM jymmmm: That WILL kill it and sterlize =)
06:55 AM XXCoder: lol work have santitizer auto mixer now
06:55 AM XXCoder: hospital grade
06:56 AM jymmmm: on the wall?
06:57 AM jymmmm: dispenser you mean?
06:57 AM XXCoder: yeah hose to sink for water
06:58 AM jymmmm: Huh? I don't understand. Hospitals have alcohol hand santizers hangn on the walls everywhere
06:58 AM XXCoder: i dont work at hospital :)
06:58 AM jymmmm: I know, but what do you mean hose to sink?
06:59 AM XXCoder: its a auto mixer, oit gets water from sink and mixes in precise amount of chemical to make it into santizer that you pour into sprayers
06:59 AM jymmmm: Hmmm, never heard of it
07:00 AM jymmmm: XXCoder: and what is it sprayed on?
07:01 AM XXCoder: something like, but not same as this https://lh3.googleusercontent.com/proxy/FZ_QA3rtcdTwpmDZAOg_Ku943bWTf5PP9NzN7y4s_i8a0f65yNzzO7ixNjqNcolJu-ijSgmb4JcjR9ZOvHi6qfe_JRDC6BbRFdYHO-vgHabXiZM
07:01 AM XXCoder: sprayed on all metals and everything else to keep it serlete. we get a lot of metals from china
07:01 AM XXCoder: but alsomany other places thats ponentally infectious.
07:01 AM jymmmm: Ah ok, that one is used in a bar
07:01 AM XXCoder: it lasts longer on metals after all. days.
07:02 AM jymmmm: it's metal, just torch it, =)
07:02 AM XXCoder: company had a scare when someone was coughing a lot and they send him home
07:02 AM XXCoder: it wasnt coronavirus but yeah
07:02 AM jymmmm: Well, at least they are taking measures
07:03 AM XXCoder: yeah
07:03 AM XXCoder: compare it to amazon
07:03 AM XXCoder: they dont even test workers for coronavirus
07:03 AM jymmmm: I still say torch the metal with a weed torch
07:03 AM XXCoder: lol
07:03 AM jymmmm: I'm serious
07:04 AM jymmmm: a lot more effective that a liquid solution
07:04 AM jymmmm: that may or may not cover every sq mm
07:04 AM XXCoder: i know. just that thats simply not a solution
07:04 AM XXCoder: we have too many metals.
07:04 AM jymmmm: and sparting them is more effective?
07:04 AM jymmmm: spraying*
07:04 AM XXCoder: sure as you can spray em as you run
07:05 AM jymmmm: Eh, it's all about contact time.
07:05 AM XXCoder: honestly I dont bother.
07:05 AM XXCoder: i just dont make my fingers friends with my eyes nose and mouth
07:05 AM jymmmm: Even using bleach, yu need a one minute contact time with the surface
07:06 AM jymmmm: ...to kill bugs
07:07 AM jymmmm: Sorry for all this ranting, but the WHO and CDC just pissing me off witht he BS information they are giving out.
07:07 AM XXCoder: like what?
07:08 AM jymmmm: They are not telling peopl abut bleach as example
07:08 AM jymmmm: promoting alcohol over soap
07:09 AM XXCoder: bleach unfortnately is bit outdated as bunch of germs can live though that
07:09 AM XXCoder: viruses too
07:09 AM jymmmm: telling people not to wear masks, etc
07:09 AM jymmmm: since when?
07:09 AM XXCoder: work one isnt bleach but more modern more powerful one
07:09 AM jymmmm: Like I said, it's about contact time.
07:10 AM XXCoder: since evolution was invented by god lol
07:10 AM jymmmm: Name one that bleach isn't effect against?
07:10 AM XXCoder: its been a long time since i read that
07:10 AM XXCoder: did some research when I was told not to use bleach at old job
07:11 AM jymmmm: Well, they might have not liked the smell
07:11 AM XXCoder: from what i understood whatever chemical it was smelled worse
07:11 AM rmu|w: i want to see the superbug that survives bleach
07:11 AM XXCoder: just dont drink bleach!
07:11 AM jymmmm: EVERYTHING the CDC is suggesting is either bleach or ammonia based.
07:12 AM jymmmm: and the list is 24 pages long
07:12 AM jymmmm: and gawd help the person that treis to use both at the same time
07:12 AM rmu|w: it's unlikely that resistance develops against bleach or iodine
07:12 AM XXCoder: if you want to drink bleach please add some ammonia with it
07:13 AM XXCoder: you will never get sick again
07:13 AM jymmmm: OH and hyrogem peroxide based, but they didn't say the consentration
07:13 AM XXCoder: no, I kid that's death
07:13 AM jymmmm: I doubt it's consumer grade
07:13 AM jymmmm: Lastly was ozone
07:15 AM jthornton: sodium hypochlorite is used by most water treatment plants to purify the water
07:15 AM jymmmm: I know cryprosprium (sp) isn't effected by bleach, but it's so large that it can be filtered out
07:15 AM jthornton: we had a problem with an injection pump on a rig I worked on and too much sodium hypochlorite will make you not want to drink the water lol
07:16 AM XXCoder: fun heh
07:16 AM rmu|w: cryprosprium?
07:17 AM jymmmm: jthornton: Sodium hypochlorite (bleach) or calcuim hypochlorite ?
07:17 AM jthornton: <jthornton> sodium hypochlorite is used by most water treatment plants to purify the water
07:18 AM jymmmm: XXCoder: Cryptosporidium
07:18 AM XXCoder: ok
07:19 AM p0g0: fwiw, UV
07:19 AM p0g0: if you have the lamps
07:19 AM XXCoder: the skin damaging uv-c
07:19 AM XXCoder: if i remember name of that range of uv anyway
07:19 AM jymmmm: jthornton: Yes, I read, but calcuim hypochlorite has twice the hypochlorite is why I was asking for clarification.
07:19 AM p0g0: UV+O3 for the aerosol version of the Piranha Solution (see wikipedia)
07:19 AM p0g0: oh yeah, no lookie
07:20 AM XXCoder: https://www.youtube.com/watch?v=1m0TQjBRcFo
07:20 AM p0g0: It's way wrong for your eyes
07:20 AM XXCoder: that thing is dangerous as hell
07:20 AM p0g0: But if you have a closet/ etc and want a pervasive antibiota.
07:21 AM XXCoder: yep uv-c
07:21 AM p0g0: I am not suggesting anything for things that you want to stay alive, just things you want to kill
07:21 AM p0g0: so, not fit at all for plants/pets/people
07:22 AM XXCoder: i hope that guy wore goggles
07:22 AM p0g0: But reactive oxidative species (RAS) rob carbon efficiently
07:23 AM * SpeedEvil has a UVC tube on order.
07:23 AM p0g0: It'll peel your paint
07:23 AM SpeedEvil: For package /grocery decontamination.
07:23 AM p0g0: (the UV)
07:24 AM jymmmm: SpeedEvil: You probably have a protoplasma ray gun on order too
07:24 AM p0g0: eh ROS, my typos are getting bad today
07:24 AM jymmmm: SpeedEvil: you building a little light proof chamber for it too?
07:27 AM SpeedEvil: jymmmm: That, and not bothering being in the room at the same time
07:27 AM XXCoder: video later on he says hes not staring at light and are wearing goggles. good.
07:28 AM XXCoder: risking blindness is dumb
07:28 AM SpeedEvil: UVC is really good at giving you skin cancer too.
07:28 AM SpeedEvil: Not just eye issues.
07:28 AM XXCoder: well I have 3 "major" senses left. sight does everything basically
07:28 AM XXCoder: so of course im concerned with eyes first ;)
07:29 AM SpeedEvil: Skin is important.
07:29 AM XXCoder: skin cancer is most curable one of all
07:29 AM XXCoder: 95%+ cure rate
07:30 AM p0g0: yeah, still, you don't want to be illuminated. Full Stop.
07:30 AM XXCoder: indeed
07:30 AM XXCoder: if i wanted to use it for my room, for example
07:30 AM p0g0: use an extension cord, and don't plug it in until you are out of LOS
07:30 AM XXCoder: I would shut my eyes when standing outside my room with small gap so I can turn it in
07:30 AM XXCoder: on
07:30 AM XXCoder: close right after
07:31 AM SpeedEvil: Best kind of cancer to have is one you die with, not of. (research found for example 80% or so of corpses had thyroid tumors for example. Just irrelevant ones.
07:31 AM XXCoder: wait maybe a minute? dunno then close eyes again nd turn it off right after
07:31 AM p0g0: radioactive iodine works too
07:31 AM p0g0: for the thyroid
07:31 AM p0g0: but that's sort of a non-issue here
07:32 AM p0g0: anyway, off to wander in the UV laden sunlight
07:32 AM p0g0: l8r all
07:32 AM SpeedEvil: I would quite like a powerful gamma source for irradiating stuff.
07:33 AM XXCoder: block of plutoium with barriers against wrong types of radation? heh
07:36 AM rmu|w: SpeedEvil: it's time for open source build-at-home free electron laser
07:36 AM SpeedEvil: Everyone should have a free electron LASER.
07:37 AM XXCoder: free electron laser interesting
07:37 AM SpeedEvil: I mean, they're free. It's in the name.
07:38 AM XXCoder: what bullshit
07:38 AM SpeedEvil: Pascalisation is a neat technology too.
07:38 AM XXCoder: tons of videos explaining about it and none showing it
07:38 AM SpeedEvil: - proteins denature at 60000PSI or so, deforming and damaging bacteria and viruses.
07:39 AM SpeedEvil: Fun part is being able to do it in a vessel more than an inch across.
07:42 AM rmu|w: 340MPa
07:42 AM rmu|w: a lot
07:43 AM SpeedEvil: Indeed.
07:43 AM SpeedEvil: The raw chamber is sort-of-doable.
07:44 AM SpeedEvil: The seals are rather more annoying.
07:48 AM rmu|w: https://en.wikipedia.org/wiki/Free-electron_laser
07:50 AM rmu|w: not quite in the gamma regime yet, but sufficient to strip all elements of most of their electrons
07:54 AM sync: UV-C cleaning of surfaces is really neat
07:55 AM sync: it will blaze greases right off stuff
08:07 AM gregcnc: interesting they are used in kitchen hoods. i don't think I've ever seen it, or it's not obvious
08:15 AM _unreal_: I have a UV sterilizing wand battery powered somewhere
08:15 AM SpeedEvil: If it's not UVC it's mostly useless.
08:16 AM SpeedEvil: If it is UVC it is actively dangerous.
08:16 AM SpeedEvil: The reason UV gives you skin cancer is the same reason it kills bacteria/viruses. (inactivates)
08:16 AM _unreal_: its uvc
08:17 AM _unreal_: and you have to ware glasses when using it
08:17 AM _unreal_: wear
08:17 AM SpeedEvil: ah
08:17 AM _unreal_: recomends long sleeves and pants
08:17 AM _unreal_: its for home cleaning
08:18 AM _unreal_: wave it over beds sinks bath room areas what ever
08:27 AM SpeedEvil: https://sci-hub.se/https://link.springer.com/article/10.1007/s00705-010-0847-1 - gives 100J/m^2 UVC as killing 99% of various viruses. Extrapolating the curve, 200J should be good for at least 99.99%
08:29 AM _unreal_: ! I should be designing and milling corona MONSTER drink coasters :)
09:11 AM sync: gregcnc: most of the hood UVC systems are in commercial ones
09:11 AM sync: as it will break down the smells and keep the fats liquid
09:12 AM sync: so they just drain out or are just blown out
09:15 AM jymmmm: SpeedEvil: Over what duration? an hour exposure?
09:16 AM SpeedEvil: To a first approximation, it doesn't matter.
09:16 AM SpeedEvil: Unless you appreciably heat the surface layer.
09:16 AM SpeedEvil: The viruses are not replicating, and have no repair mechanism, so it's the same if it's a second or a week.
09:16 AM jymmmm: SpeedEvil: I mean the uvc bulb you ordered
09:17 AM jymmmm: I'm doubting it's "instant"
09:17 AM SpeedEvil: Oh. 18W*2, so about that would treat 1m^2 in conservatively 20s.
09:18 AM jymmmm: That's it? 20s? I'd think at least 60s to 5m for a whole room
09:20 AM SpeedEvil: 1m^2 is not a whole room.
09:20 AM gregcnc: how much damage does the ozone do?
09:21 AM SpeedEvil: Overnight could treat 1000m^2, but only if it was clean and not reflected. 50m^2 maybe really?
09:22 AM SpeedEvil: I have not investigated that as I don't care, as I'm not using it for large volumes.
09:22 AM jymmmm: SpeedEvil: gotcha
09:22 AM jymmmm: gregcnc: very effecive
09:22 AM jymmmm: so says the CDC
09:34 AM _unreal_: freaking amazing I cant find a single tape measure
09:39 AM SpeedEvil: For your average 8*8cm tape measure, take the floor area of your house/workspace, and multiply the area by 100, and buy that number of tape measures.
09:42 AM jymmmm: Pffff, I got mine free from HF, so there's at least one every 6ft
09:47 AM unterhaus_: there is a lab on campus that decided to solve the tape measure problem by buying a large bucket full
09:47 AM unterhaus_: the bucket is almost always empty
09:47 AM SpeedEvil: Glue tape measures to the desks.
09:48 AM unterhaus_: the real problem is that tape measures are like chameleons, they blend it
09:49 AM unterhaus_: but if you stand very still and don't look for a tape measure, one will appear
10:19 AM skunkworks: we have the same problem.. also with pens volt meters and flashlight
10:28 AM _unreal_: fewwww that got hot. I was desoldering parts
10:28 AM _unreal_: refering to the hot air station
10:28 AM _unreal_: took a bit at full power to remove a few of the parts
10:28 AM _unreal_: M'f'ers
10:29 AM _unreal_: ok time to hunt for the @#$@#$ tape measure again
10:34 AM p0g0: gregcnc: O3 is hard on some things, steel & rubber, for example. I can link you to tables of material tolerance, but you could just search for them too, they are common enough on the web. You are not likely to make a lot of O3 in a hurry (you can if you really try), so it is more a question of long exposure. Finding elastomers that are O3 tolerant takes a little study, but they are out there (eg: viton). O3 basically degrades to H2O2 and does that
10:34 AM p0g0: fairly quickly, what UV, even the longer wavelengths, does to O3 is that it promotes the degradation. Modest UV exposure nails 99% of ambient O3, which briefly becomes O and O2, but the O is just behind Fluorine for charge density, so it tends to bond Very Fast, and the most common reaction product is H2O2 (but it might get lucky and meet something besides water). So, damage really depends on how much, how long, and what material.
10:35 AM gregcnc: right exactly what i was referring to, but I don't know how that equates to real world
10:37 AM p0g0: I use a UV + O3 regime to treat water, the O3 concentration is low, but even that will corrode steel pretty quickly. I had a common aquarium air pump manifold fail in a couple of months- steel that just got Swiss Cheesed.
10:38 AM p0g0: viton, PEX, teflon... those all persist well enough to be practical.
10:40 AM p0g0: I use a viton elastomer in the air/O3 pump to entrain the O3 into water, then zap that with UV and "air strip" the water- it takes recirculation to clear all the carbon, but it works too.
11:06 AM _unreal_: ok guess its time to design a cap holder
11:06 AM _unreal_: you know I'm blown away how I could not find the caps I needed on line for anything less then $80
11:06 AM _unreal_: and no sooner had I ordered them. then I find the caps in the dumpters at work :/
11:08 AM _unreal_: I just dont understand why I could not find on line the caps I needed
11:08 AM _unreal_: now I'm googling and I'm finding a shit load on line as well for next to nothing
11:10 AM Tom_L: patience
11:15 AM _unreal_: ARG..
11:36 AM jymmmm: Are stores intentionally NOT selling N95 masks? On amazon barely anything comes up
11:38 AM SpeedEvil: Everyone bought them, listings pulled.
11:38 AM jymmmm: Hmmm
11:38 AM SpeedEvil: I note as an aside I checked my favoirites (purchased items) list on my online grocery store. Out of 197 items, 93 are unavailable.
11:40 AM jymmmm: eeeesh
11:41 AM jymmmm: I REALLY rather not wear my p95 half mask
11:42 AM jymmmm: then I would sound like Darth Vader =)
11:42 AM Tom_L: https://www.forbes.com/sites/amyfeldman/2020/03/19/talking-with-the-italian-engineers-who-3d-printed-respirator-parts-for-hospitals-with-coronavirus-patients-for-free/#f6eb7b278f1a
11:42 AM Tom_L: jymmmm, make your own
11:44 AM jymmmm: Tom_L I can't view that page plus n 3d printer
11:53 AM _unreal_: jymmmm, this corona virus is one of the lowest infection rates going around the world and the media is pretending its "28 days later"
11:53 AM jymmmm: Lowest? where do you get that from?
11:53 AM _unreal_: usa has 200 something now DEAD in 3 months
11:53 AM _unreal_: jymmmm, CDC web site
11:54 AM _unreal_: h1n1 killed tens of thousands in weeks
11:54 AM SpeedEvil: Spell Exponential and use it in a sentance.
11:54 AM jymmmm: that doens't make senseee
11:54 AM _unreal_: and infected MILLIONS around the world in just weeks
11:55 AM _unreal_: jymmmm, look up h1n1, look up sars look up ETC.....
11:55 AM jymmmm: but didn't cause a complete shutdown like corona has
11:55 AM _unreal_: the numbers are so PATHETICLY off
11:55 AM _unreal_: bs
11:55 AM gregcnc: world is quite different today
11:55 AM _unreal_: jymmmm, I use to work for the world leader in bio medial research the Jackson lab www.jax.org
11:55 AM _unreal_: I use to be a nurse
11:55 AM _unreal_: I use to be a med tech
11:55 AM _unreal_: and the list goes on
11:55 AM Tom_L: yeah, viruses spread over the internet like wildfire :)
11:56 AM SpeedEvil: Did you used to be an adventurer?
11:56 AM _unreal_: I'm getting endless requests to go back to nursing right now by mail
11:56 AM Tom_L: oh... not that kind of virus
11:56 AM jymmmm: That doesn't change the fact that no other pandemic has shut down things like this has.
11:56 AM _unreal_: ahhhh people shut stuff down
11:56 AM _unreal_: the FEW are controlling the masses
11:57 AM _unreal_: there is something like 500,000 cases of corona virus world wide so far
11:57 AM jymmmm: as always
11:57 AM _unreal_: H1N1 was millions
11:57 AM _unreal_: where was the out range
11:57 AM _unreal_: rage
11:58 AM SpeedEvil: H1N1 was in the millions when it got into the millions.
11:58 AM SpeedEvil: Look at the response to it and the deaths when the cases were in the 300K range.
11:58 AM _unreal_: jymmmm, if you believe ANY OF this bs I'm sorry for you
11:58 AM _unreal_: SpeedEvil, there was a responce?
11:58 AM _unreal_: Oh thats right obama was pres. nothing to see here move along
11:59 AM _unreal_: jymmmm, you CAN NOT claim that this crona bs is the end of the world that the media is claiming it to be. the numbers are so patheticly off its scary
11:59 AM gregcnc: https://www.cdc.gov/h1n1flu/cdcresponse.htm
12:00 PM gregcnc: "On May 4, 2009, CDC shifted from reporting confirmed cases of 2009 H1N1 to reporting both confirmed and probable cases of 2009 H1N1. At that point, more than 98% of “probable” flu virus samples were testing positive for 2009 H1N1, indicating the ever-growing scale of the outbreak"
12:00 PM gregcnc: it seems like 10% are testing positive for covid19
12:01 PM _unreal_: as I said the covid/crona virus is BS
12:01 PM _unreal_: and there are a lot of people loosing there shirts right now over it
12:01 PM _unreal_: $
12:02 PM _unreal_: has nothing to do with the health issue. its trying to crash trumps economy
12:02 PM _unreal_: election year
12:03 PM _unreal_: you'll also notice that every DEM. governer has taken the most over reaching "measures"
12:03 PM _unreal_: wait till this nov. its going to be the greatest land slide victory for rep. in history
12:04 PM _unreal_: not to mention the MEDIA blamed "right fully so" FOR ONCE china for the outbreak. then tried to blame trump for the out break. OOPS china got the rap not trump..
12:06 PM _unreal_: so jymmmm how can you have half a milling cases of something world wide. currently AFTER MONTHS. when few years ago we had 10's of milloins in the USA alone sick with past out breaks in just weeks
12:06 PM _unreal_: and NO omg responce.
12:07 PM _unreal_: there are "" paid "" scientist going on cnn etc... claiming there are going to be millions dead. EXCUSE ME I use to work for the world leader in bio research. I'm publish with them from my projects working for them..... you DONT claim anything that you dont know on an event that your still recording information on. its bio research #1. Had I done that I'd have been fired on the spot.
12:08 PM SpeedEvil: https://twitter.com/SpacePadreIsle/status/1241768125202399232
12:09 PM SpeedEvil: It is neat how much more regular and not buckled the current variant of SpaceXs production is than the first model.
12:09 PM SpeedEvil: Only very minor shrinkage at the weld joins, compared to the original, and much better surface quality. 3-4mm stainless steel 303 mostly.
12:10 PM _unreal_: SpeedEvil, wish I could go there and look but its a 3hr drive from me :(
12:10 PM _unreal_: north
12:10 PM _unreal_: i'm in way south florida
12:11 PM SpeedEvil: And they're actually building them on the 'what if we setup a line that can do >>>10/year' basis. Rather than 'this one must be perfect and will cost two billion dollars.'
12:12 PM _unreal_: hehe
12:12 PM _unreal_: 10k check rate got to make sure its good.
12:12 PM _unreal_: why did it break? oh you touch it 10k times
12:12 PM _unreal_: LOL
12:15 PM _unreal_: I'm assumign jymmmm is doing research right now or that guy is full of it and the media must be believed and knowns alll hehe
12:46 PM rmu|w: _unreal_: northern italy deployed the military to get rid of the dead. local funeral homes are overwhelmed.
12:47 PM rmu|w: _unreal_: surely that is because of a sinister chinese fake virus designed to rid trump of his rightful place in office
12:56 PM gregcnc: https://www.livescience.com/covid-19-pandemic-vs-swine-flu.html
01:08 PM p0g0: _unreal_, I'm going with the latter assumption.
01:09 PM p0g0: Not the media part, the middle bit.
01:12 PM skunkworks: rmu|w: that is 'i am sure' fake news.
01:27 PM _unreal_: arg... ve7it isnt on
01:27 PM _unreal_: I just got my motor controllers mounted to the heat sink finally
01:27 PM _unreal_: I still need to put the isolators etc.. bs on which I have not bothered to do yet but I'll get to it
01:28 PM _unreal_: rmu|w, over 5,000 people die every day from the common cold. THAT is a fact
01:29 PM _unreal_: around the world
01:29 PM _unreal_: rmu|w, that BLOWS this crona bs out of the water by many 10's of times
01:30 PM infornography: Corona 2: electric boogaloo
01:30 PM _unreal_: more peole die from gun shot murders around the world in just a few days then have die from this virus
01:31 PM _unreal_: its such a mole hill its funny
01:31 PM gregcnc: Rand Paul tested positive, Merkel's dr tested positive
01:31 PM CaptHindsight: how much alcohol can I drink before it suppresses my immune system?
01:31 PM Tom_L: CaptHindsight, i worked with a guy that couldn't work sober
01:32 PM _unreal_: CaptHindsight, I dont think your body can handle that level of consumption
01:32 PM Rab: CaptHindsight, any quantity, I suspect.
01:32 PM Tom_L: you need to build it up over time though
01:32 PM _unreal_: ! though I could be wrong
01:32 PM Tom_L: and time isn't on your side right now
01:32 PM CaptHindsight: Tom_L: not to rare with alcoholics
01:32 PM gregcnc: there will be a whiskey shortage as distillers turn to making hand sanitizer
01:33 PM Tom_L: gregcnc, never... there's always moonshine
01:33 PM gregcnc: people will be bathing in it though
01:33 PM _unreal_: ! i SUDDENLY want a capt n coke
01:33 PM CaptHindsight: had sanitizer already costs more than scotch
01:33 PM _unreal_: I hear a wine bath is good for you
01:34 PM Tom_L: CaptHindsight, not if you look around
01:34 PM CaptHindsight: had/hand
01:34 PM Tom_L: sure there are those that are trying to rape you for it
01:34 PM CaptHindsight: I really haven't looked
01:34 PM _unreal_: my boss lass week was gloating about selling TP for $20 a roll on ebay
01:34 PM Tom_L: i did have a guy going door to door selling it. i didn't answer the door
01:35 PM CaptHindsight: just TP or a full wiping service?
01:35 PM CaptHindsight: like chimney sweeps
01:35 PM _unreal_: Had I not been dealing with the worst BS job at work I've had to do in years I might have tried to find some to do the same thing :(
01:35 PM gregcnc: https://www.youtube.com/watch?v=5_iBOg5OfBg
01:35 PM _unreal_: had to grind a large number of sections
01:36 PM _unreal_: in a fuel tank
01:36 PM _unreal_: stuck late every day for a week. got home feeling off
01:36 PM Rab: _unreal_, the yacht business must be in the toilet if your boss is fussing over $20 scams.
01:37 PM _unreal_: 20yo luxury yacht with a 25' long central fuel tank
01:37 PM _unreal_: Rab, we are drowning in work
01:37 PM _unreal_: even right now
01:37 PM _unreal_: in fact we have been giving work away to other companies because we dont have the staff
01:37 PM _unreal_: :/
01:38 PM Rab: Haha, guess the wealthy are fleeing to the high seas.
01:38 PM _unreal_: no...
01:39 PM _unreal_: rather there are a huge number of boats comming into the marina to be dry docked on the HARD for major work.
01:40 PM _unreal_: LMC is at record levels
01:41 PM jymmmm: gregcnc: https://www.amazon.com/WMN_TRULYSTEP-Distiller-Moonshine-Alcohol-Stainless/dp/B00XZ381F0/
01:47 PM rmu|w: italy is not fake news, and this is additional dead on top of what they usually have. in lombardy they have about 6-8 times as much dead as usually.
01:50 PM snakedGT is now known as snaked
01:54 PM gregcnc: cases/population is high in italy, but switzerland is not far behind
01:55 PM _unreal_: all the high case count areas are also statistically the most visited by chines tourists
01:56 PM _unreal_: I'm sorry chines bio terrests
01:56 PM _unreal_: lol
01:57 PM pcw_home: cases/pop is more an indication of where you are on the curve, not really that significant, where the inflection point is is what matters
01:57 PM gregcnc: sure, but why is italy so bad? did they ignore it?
01:58 PM pcw_home: They may have had a head start with many tourists, but the shape of the curve is the important thing
01:59 PM rmu|w: _unreal_: italy stopped chinese tourists in january IIRC
01:59 PM rmu|w: _unreal_: we have some chinese tourism hotspots in austria too (hallstatt), no problems there
01:59 PM gregcnc: the shape of the curve only determine how fast its' spreading. In theory how well infrastructure can deal with it.
02:00 PM gregcnc: the curve will flatten eventually no matter what
02:00 PM pcw_home: italy has a handle on it (if you look at log (cases))
02:00 PM pcw_home: USA not so much :-(
02:01 PM gregcnc: we won't know for another week
02:01 PM _unreal_: pcw_home, usa not so much? there are just over 200 dead in the USA in 3 months
02:01 PM _unreal_: 200 NATION wide
02:02 PM rmu|w: if USA doesn't ramp up testing you will not know anything for sure
02:02 PM _unreal_: more people die from gun shot EVERY DAY
02:02 PM _unreal_: LOL
02:02 PM _unreal_: bs
02:03 PM pcw_home: Yeah NY is pretty bad, not sure when they instituted
02:03 PM CaptHindsight: well if anyone is still around in a few months RTAI has updates, openCV for auto alignment will be working, more SVG to tool paths or raster will be working
02:03 PM pcw_home: social distancing
02:03 PM CaptHindsight: looks like the Mint ISO is coming along well
02:03 PM rmu|w: estimated mortality of 0,1% is not a trivial number @ 20% of 300mio americans
02:03 PM rmu|w: that will get infected AT LEAST. more probably around 60%
02:04 PM _unreal_: rmu|w, what bs sars, H1N1 were in the 10's of thousands DEAD in just a few weeks
02:04 PM _unreal_: in the USA alone
02:04 PM rmu|w: and mortality could be as high as 3% or even more
02:04 PM CaptHindsight: 320M x 0.6 x 0.02 =
02:04 PM _unreal_: where was the out rage
02:04 PM Tom_L: they seem to be following the guidelines here pretty well
02:05 PM Tom_L: i was kindof surprised
02:05 PM rmu|w: SARS 2002/2003 was around 800 dead worldwide
02:05 PM pcw_home: covid109 has at least 10x and maybe 100X the mortality rate of H1N1
02:05 PM _unreal_: rmu|w, go look at the CDC web site
02:05 PM _unreal_: YOUR NUMBERS ARE way off
02:05 PM pcw_home: Look at log (cases)
02:06 PM pcw_home: not good
02:06 PM rmu|w: _unreal_: that number is from josef penninger who was a researcher in toronto at that time
02:06 PM rmu|w: _unreal_: wikipedia seems to agree
02:06 PM CaptHindsight: https://www.youtube.com/watch?v=GU0d8kpybVg Bring out your dead (Monty Python)
02:07 PM rmu|w: _unreal_: apeiron biotech
02:07 PM rmu|w: sorry s/biotech/biologics/
02:08 PM _unreal_: https://www.cdc.gov/flu/pandemic-resources/2009-h1n1-pandemic.html
02:09 PM rmu|w: _unreal_: so 12500 dead in one year with a population of 360mio
02:09 PM rmu|w: _unreal_: italy has 5000 dead in 2 weeks with a population of 60mio
02:10 PM pcw_home: and the US is doing less than Italy
02:10 PM jymmmm: ITaly just had 400+ dead in 24 hours this week
02:10 PM rmu|w: jymmmm: yesterday nearly 800
02:11 PM jymmmm: rmu|w: ouch =(
02:11 PM rmu|w: today it is around 600
02:12 PM pcw_home: 98 dead today in US and ramping up
02:13 PM CaptHindsight: Mr T just wants us to win high score
02:13 PM pcw_home: social distancing in CA and NY should help
02:14 PM pcw_home: Yep we will likely beat Italy in # cases is less than a week
02:14 PM pcw_home: and China in 2
02:14 PM jymmmm: pcw_home: in reported infections you mean?
02:14 PM jymmmm: China had zero new cases yesterday I believe
02:15 PM pcw_home: yes so it is possible to get a handle on it if you act quickly
02:16 PM gregcnc: north korea say they haven't had any...
02:16 PM CaptHindsight: it is likely that we will have a to wait a few months to see more accurate numbers since some countries tend to fudge them
02:16 PM CaptHindsight: control the narrative
02:16 PM _unreal_: CaptHindsight, you dont think "" china "" would fudge anynumbers do you ;)
02:16 PM jymmmm: pcw_home: you have it worse being in the Bay Area with population denisty being 9000 per sq mile, NAtional avg is 1500 per sq mile.
02:17 PM CaptHindsight: can't count tests that didn't happen
02:18 PM pcw_home: Not sure if population density is as important as number of social contacts
02:18 PM _unreal_: pcw_home, THAT I agree with
02:19 PM CaptHindsight: new categories: Shared tooth brush, shook hands, sneezed nearby, waved from across the street, IRC only
02:25 PM rmu|w: _unreal_: what does it cost in US to get tested?
02:25 PM _unreal_: how should I know
02:26 PM rmu|w: I assumed you are in the US?
02:28 PM _unreal_: I have no intrest in getting tested. I have not researched it ETC..
02:28 PM jdh: it would cost nothing. if you could get tested. which seems unlikely
02:29 PM rmu|w: so US numbers are fudged too
02:29 PM _unreal_: SWEET IT FITS PERFECT
02:29 PM _unreal_: my part I just cut fits into my case flawless
02:29 PM _unreal_: I have but to drill a few holes and tap a few holes to mount my my over sized soup can caps
02:31 PM Javabean: rmu|w: best i can tell you https://kvia.com/coronavirus/2020/03/19/what-does-it-takes-to-be-tested-for-the-coronavirus-in-el-paso-heres-the-answer/ no cheap
02:31 PM Javabean: s/"no cheap"/"not cheap"
02:32 PM _unreal_: Personally I think china just needs to be banned from visiting the world during flu season
02:32 PM _unreal_: problem solved
02:33 PM rmu|w: MERS didn't originate in china
02:34 PM Tom_L: yeah you can't blame them for _everything_
02:34 PM rmu|w: and following trumps "chinese virus" rhetoric, china says the virus was introduced by us american soldiers competing in some kind of fitness event in wuhan
02:35 PM Javabean: the first "showings" of this viral infection were in november, in hubei province(which contains wuhan)
02:39 PM _unreal_: rmu|w, the corona virus comes from bats
02:39 PM _unreal_: its a known fact that chines eat bats in some areas. old traditions
02:39 PM _unreal_: veegee, sup
02:39 PM rmu|w: _unreal_: bat bites soldier, soldier is infected
02:39 PM _unreal_: ve7it,
02:40 PM _unreal_: ve7it, I got the drivers mounted to my heat sink
02:40 PM _unreal_: ve7it, question for ya
02:41 PM _unreal_: I'm going to use an active cooling on the heat sink. I'm mounting all 3.1 drivers onto the heat sink. and I'm going to put a lid over the heat sink with active cooling sourcing from the middle
02:41 PM _unreal_: any worries of over heat production? also the heat sink its self will be in tight contact with the metal box enclosure.
02:42 PM _unreal_: I dont think I have any heat disipation issue
02:42 PM _unreal_: especially with active cooling
02:43 PM ve7it: you wont really know until you get the machine moving.... Your motors are not a high current draw, so unless they are stalled or oscillating they will not be drawing much current
02:44 PM _unreal_: and I'm running threaded rod so the motors shouldnt have a lot of constant torque issues. the threaded rod should take it
02:45 PM _unreal_: I am going to have to do something about the X motor though. not right now but sooner or later
02:45 PM _unreal_: also ve7it any thoughts on what STEP rate I could get out of the PAR port? I'm going to switch to a mesa driver. but I just took over my fathers mortgage so $$ is less liquid
02:46 PM _unreal_: til I get this machine running :)
02:47 PM ve7it: swag... 20khz.... maybe more as the timing is not critical as with steppers
02:48 PM _unreal_: blaaa
02:48 PM _unreal_: hehe
02:48 PM _unreal_: if I did my numbers right I'm going to need 60khz to run full speed
02:48 PM _unreal_: ehhe
02:48 PM _unreal_: and full speed is going to be like 800mm/m
02:49 PM _unreal_: not fast but VERY torque'y
02:49 PM ve7it: you can use the pulse multiplier feature in the drive.... you can make 1 increment on the command equal multiple position encoder counts
02:50 PM _unreal_: and high resolution
02:50 PM ve7it: mechanically... you probably dont need resolution much higher than 0.001"
02:50 PM _unreal_: is that a setting or a feature?
02:51 PM _unreal_: ve7it, I forget what my resolution is to be honist
02:51 PM _unreal_: not including encoders
02:51 PM _unreal_: pulse multiplier is that a command feature or a setting?
02:51 PM _unreal_: meaning can it be called or is it an ON/off FEATURE
02:52 PM CaptHindsight: "Deadly nanoparticles ruin the lives of 3% that they touch"
02:53 PM ve7it: (x)pc cmd multiplier = 3
02:53 PM ve7it: set via serial link
02:54 PM _unreal_: ve7it, ok did the quick math. the motor has to turn 52 times to move any axis 1"
02:55 PM _unreal_: motor gear 12 teeth, main pully 48 teeth, to 1/2-13 TPI
02:57 PM _unreal_: ve7it, arg... I still need to get the heat sink isolation setups done on the opamps
02:57 PM _unreal_: I have all the parts just a matter of bothering to do it
02:57 PM _unreal_: ARG.
02:57 PM _unreal_: I dont want to :)
03:11 PM CaptHindsight: I wonder what % of people during isolation will study or learn something new?
03:11 PM * Javabean grumbles
03:17 PM gregcnc: dude it's a vacation
03:18 PM SpeedEvil: Today I learned to measure twice and cut once.
03:18 PM SpeedEvil: I keep needing to learn this alas.
03:19 PM CaptHindsight: gregcnc: true, many won't have one again for a while
03:20 PM Javabean: many will also get to go on a permanent vacation, as they will be turning in their meatsuit
03:22 PM CaptHindsight: visit with past friends and family
03:23 PM * JT-Shop has been cleaning and sorting out the shops and garage
03:23 PM gregcnc: yeah that's what I need to do. i did start
03:23 PM JT-Shop: I wish I could go to the scrap yard and sell all the scrap so I'd quit tripping over it
03:23 PM JT-Shop: I had to in order to get all the blue vehicles in the garage
03:28 PM CaptHindsight: I had customers emailing at 5am
03:28 PM CaptHindsight: in the USA
03:28 PM CaptHindsight: on Sunday
03:29 PM Tom_L: and did you reply?
03:31 PM CaptHindsight: i called them back, told them I am asleep and will get back to them later
03:33 PM XXCoder: poor red vehicles left out in rain ;)
03:38 PM -!- #linuxcnc mode set to +v by ChanServ
03:42 PM cradek_ is now known as cradek
03:52 PM Tom_L: CaptHindsight, you're in chicago right?
03:53 PM Tom_L: looks like Illinois has been shut down
03:56 PM CaptHindsight: Tom_L: yeah, Stay at Home, 6ft rule
03:57 PM CaptHindsight: just about to go for a walk outside, that is still fine plus I'm way out of the city at the edge of corn
03:59 PM roycroft: in most places with shelter-in-place, outdoor exercise is still permitted as long as it's solitary
03:59 PM roycroft: which direction do you live from downtown?
04:00 PM roycroft: where i grew up in illinois i was literally a few blocks from corn fields
04:00 PM roycroft: but nobody in my town seemed to be aware of that, because they all worked in chicago
04:00 PM roycroft: i am from the south suburbs, right on the will county line
04:01 PM roycroft: my neighbors knew the illinois central train schedule by heart, but did not know about the existence of corn fields
04:02 PM CaptHindsight: I'm way out in McHenry county, 50 miles from downtown
04:03 PM CaptHindsight: more farm than city
04:03 PM CaptHindsight: still pass cornfields to get here
04:04 PM CaptHindsight: border Wi
04:05 PM CaptHindsight: just to the west it's just farm until Rockford
04:09 PM unterhaus: we know about corn fields because they fertilize them with cow poop
04:09 PM unterhaus: hard to ignore
04:11 PM roycroft: aah, you're the opposite direction from where i lived
04:11 PM roycroft: i grew up in cook county
04:11 PM roycroft: but a the very end of the commuter rail line
04:11 PM roycroft: a lot closer in that you are
04:12 PM roycroft: i was 30 miles from downtown
04:15 PM CaptHindsight: i grew up in the city
04:16 PM CaptHindsight: in the hood
04:16 PM CaptHindsight: gang fights to and from school, the usual
04:18 PM CaptHindsight: HS was just west of downtown
04:19 PM CaptHindsight: took the subway
04:33 PM XXCoder: I lived at almost more places than my childhood years
04:34 PM XXCoder: and 6 states in least
04:37 PM p0g0: XXCoder, one of my senators has cv19...
04:37 PM p0g0: Last time he was ill, he went to canada for treatment.
04:37 PM p0g0: I wonder if they will let him in this time.
04:37 PM XXCoder: ?
04:38 PM p0g0: Rand Paul
04:38 PM XXCoder: yeah just unsure what youre repling to
04:38 PM * JT-Shop wore mukluk's and walked through the woods to get to school
04:38 PM p0g0: I wasn't replying as much as stating
04:38 PM XXCoder: paul is only one who voted against coronavirus funding too
04:38 PM XXCoder: and hes first. hah
04:38 PM p0g0: yes
04:39 PM p0g0: he is a twit of the first water.
04:39 PM XXCoder: oh sorry i was chatting in other channel about it, thought you was there also but repling to wrong channel
04:39 PM p0g0: ah, no- I had to restart a session, my vm crashed
04:40 PM XXCoder: do you know DOJ tried to get motion passed so they can imprision anyone
04:40 PM XXCoder: not sure if they succeeded or not
04:40 PM p0g0: martial law stuff? but the prisons are a hotbed.
04:41 PM p0g0: Well, the gov has forced a guy who tested positive and wanted to socialize to stay home with a cop outside his door. I found that sane, given the guys intent to spread cv.
04:42 PM XXCoder: barr is hugely interest conflicted. i wonder if trying to concerate immgrants and "oh oops they all died from virus my bad"
04:42 PM p0g0: I am waiting for the elections to get called off
04:42 PM XXCoder: that is extremely hard to do
04:42 PM p0g0: barr is <expletive deleted>
04:42 PM XXCoder: there is no povisions for delaying election. none.
04:43 PM p0g0: heck yeah it is hard, but when have these folks played by any rules?
04:43 PM XXCoder: vote must be done by certain date and president pledged in by jan 13th, and take position by 20th
04:43 PM XXCoder: true
04:43 PM p0g0: They've postponed them in a bunch of states already
04:44 PM XXCoder: primaries is different
04:44 PM p0g0: Heck, the KY legislature banned the public but kept in session for more than a week, and passed some really foul legislation, stuff they had tried before but got mobbed for it....
04:44 PM XXCoder: president votes dont have ANY povisions for delay
04:45 PM p0g0: Yeah, even in the civil war, etc...
04:45 PM XXCoder: and presidency ends at jan 20. so if failed to vote the position is empty
04:45 PM gregcnc: NY just added 4800 cases
04:45 PM p0g0: but again, McConnell has buggered the judiciary, barr runs protection, who will actually enforce it?
04:45 PM XXCoder: you know of that famous one president refused to start on sunday jan 20th so for one day usa didnt have a president
04:46 PM p0g0: they gave Bush II an extra second on the leap year fix...
04:46 PM p0g0: I noticed.
04:47 PM XXCoder: sentors is pushing so many crap judges
04:47 PM XXCoder: only basis being loyality
04:47 PM p0g0: That's all McConnell
04:47 PM XXCoder: we have huge mess in DOJ
04:47 PM XXCoder: incuding that crying rapist judge
04:47 PM p0g0: I am trying to get folks to move to Kentucky long enough to vote him out.
04:48 PM p0g0: One doesn't need to actually be here long at all, some weeks really.
04:48 PM XXCoder: good luck :)
04:49 PM XXCoder: that guy need to be out
04:49 PM p0g0: yeah, I am not getting any takers.
04:49 PM XXCoder: hes single most active on breaking usa
04:49 PM XXCoder: more so than president
04:49 PM p0g0: He owns the local machines, and started gerrymandering here in the 90s
04:49 PM XXCoder: and hes been there for quite a while
04:49 PM XXCoder: he owns voting machines?
04:49 PM XXCoder: conflict of interest aloy!
04:49 PM p0g0: He is a carpetbagger, moved up from the south to run for Mayor of Louisville
04:50 PM p0g0: No, he owns the county and state Republican party
04:50 PM XXCoder: ahh ok
04:50 PM p0g0: And by doing that, he can gerrymande after each census
04:51 PM p0g0: And that is a positive feedback loop
04:51 PM XXCoder: yeah
04:51 PM XXCoder: i also want ranked vote
04:51 PM p0g0: It's worked all across this nation
04:51 PM XXCoder: so third parties have better chance
04:51 PM p0g0: I want folks to get into the machines
04:52 PM p0g0: so they get honest
04:52 PM XXCoder: say supposing bernie didnt join democrat group and are independant
04:52 PM XXCoder: I would vote for him #1 then biden #2 and no third
04:52 PM p0g0: 3rd parties mostly mean that a losing candidate wins
04:52 PM XXCoder: so if bernie dont win my vote would transfer to biden
04:52 PM p0g0: yeah, ranked
04:52 PM p0g0: not how the game is played
04:52 PM XXCoder: not this time no. we really need it.
04:53 PM p0g0: yeah, well, I think we might be more likely, albeit not very, to win the feds to the point we can get a uniform national law on districting, and kill gerrymandering as it now exists.
04:54 PM p0g0: That will be A Giant Step towards real representation.
04:54 PM XXCoder: there is different way to do something lemme find that video
04:54 PM XXCoder: 3 reps per region not 1. larger region
04:54 PM XXCoder: so gerrymangering might be able to get one in for sure, leaving ither 2
04:55 PM XXCoder: gerrymangering is much harder to do
04:55 PM XXCoder: and less benefits
04:55 PM XXCoder: trump needs to shut his mouth https://www.huffpost.com/entry/trump-fauci-coronavirus-hloroquine-azithromycin_n_5e768e4fc5b6eab77949660d
04:55 PM p0g0: I've been in this game waist deep for a long time, I think we can get some progress on gerrymandering.
04:56 PM p0g0: (mother was the VP of the state's League of Women Voters), I started lobbying when I was 12.
04:56 PM XXCoder: please, get ranked in
04:56 PM XXCoder: that'll start changes
04:56 PM p0g0: I don't see us winning that fight yet
04:56 PM XXCoder: make it party thing for now
04:56 PM XXCoder: for primaries
04:56 PM XXCoder: then slowly push it into main voting also
04:57 PM p0g0: I think that is what comes after we elect folks that represent the will of the public, not the funders.
04:57 PM XXCoder: we have to start somewhere
04:57 PM XXCoder: https://www.youtube.com/watch?v=QT0I-sdoSXU think thats it
04:58 PM SpeedEvil: p0g0: Real progress on gerrymandering has been made in the last 20 years or so.
04:58 PM p0g0: yeah, and if you look at how GIS and demographic analysis has made the construction of voting districts so toxic that the elected gets to chose the voters (ass abckwards from the design of this nation's government) that has made gerrymandering way efficient.
04:59 PM p0g0: not here SpeedEvil, it has been compounded and doubled down 3x in the last decades,
04:59 PM Deejay: gn8
04:59 PM SpeedEvil: p0g0: Oh - you meant progress in the other direction. :)
04:59 PM andypugh: XXCoder: Huffpost are part of Verizon, and Verizon make me go to 30 separate “partner” websites to turn off cookies. So that’s not happening.
04:59 PM p0g0: The Cambridge Analytica +arcinfo
05:00 PM XXCoder: andy noscript should block nearly all cookies
05:00 PM p0g0: I was working a bill on local control of medical waste incinerators in KY and watched my IT fellows run around the capitol making the first GIS based districts.
05:01 PM XXCoder: andypugh: I also use disconnect
05:01 PM p0g0: We haven't had honest elections since.
05:01 PM p0g0: noscript does most of it.
05:02 PM p0g0: SpeedEvil, the only "correction" to your sardonics is "30 years", it has been active here for almost that long.
05:03 PM SpeedEvil: Indeed.
05:03 PM p0g0: There were only a handful of folks with arcinfo talent back then, we all knew one another.
05:03 PM p0g0: In KY
05:16 PM XXCoder: fuck this scares me. https://news.yahoo.com/federal-law-enforcement-document-reveals-white-supremacists-discussed-using-coronavirus-as-a-bioweapon-212031308.html
05:27 PM SpeedEvil: My GIS experience is limited to drawing a lot of stuff in openstreatmap in Fif.
05:27 PM SpeedEvil: e
05:35 PM p0g0: SpeedEvil, if you want a good and free tool, microdem. Don't get too twitched by the milspec side. I use it for LOS microwave stuff.
05:36 PM SpeedEvil: yeah - OSM tools work fine for what hyper-limited stuff I want to do
06:41 PM _unreal_: got a lot done today on the machine
06:42 PM _unreal_: controller related, and power system
06:42 PM * SpeedEvil is currently in a state of indeterminancy on glue.
06:42 PM _unreal_: ?
06:42 PM _unreal_: glue
06:42 PM SpeedEvil: It might be set, or it might not be, I have not read the instructions.
06:42 PM _unreal_: what kind of glue?
06:42 PM SpeedEvil: Construction adhesive.
06:43 PM SpeedEvil: Gluing together shear stiffener members for my shelving.
07:21 PM veegee: ok Fronius is overpriced
07:21 PM _unreal_: ?
07:21 PM veegee: what are some other good welder manufactuerers?
07:21 PM veegee: ESAB? Lincoln Electric?
07:22 PM SpeedEvil: Trustfire.
07:22 PM Rab: Miller?
07:22 PM _unreal_: miller time :)
07:22 PM _unreal_: dont mind if I do
07:23 PM veegee: no sum ting wong brand please
07:23 PM veegee: if they have engrish anywhere, that's an instant no no
07:24 PM veegee: no spek da engrish? not so gud wun
07:25 PM veegee: I have no respect for people who refuse to learn to speak english these days. I'm not white nor is english my first language but I don't expect the rest of the world to speak my native language
07:29 PM Tom_L: veegee, Miller
07:29 PM Tom_L: at the time, i liked the feed on the miller over the lincoln
07:29 PM CaptHindsight: Eye suspect everyjuan to speak dah English
07:31 PM * flyback puntcunts veegee
07:31 PM flyback: BMCC
07:40 PM _unreal_: ok so I'm ready to start loading my cnc pc with lcnc, not sure which version to download. I'm going to start off using the par port onboard only untill I get a mesa controller.
07:41 PM _unreal_: dont really know much about the difference between wheezy, streach, buildbot etc...
07:42 PM andypugh: Go for the stretch uspace ISO.
07:43 PM andypugh: It will probably work fine, and is what you need if you want to use an ethernet Mesa card
07:43 PM _unreal_: ! shit I dont know which cpu is in that system
07:44 PM _unreal_: brb
07:44 PM _unreal_: ya I'm looking at getting the 7i92
07:44 PM Rab: My computer had great latency with Wheezy, but Wheezy was EOL and no longer updated. I upgraded to Stretch and latency is terrible. I guess it's the difference between RTAI and PREEMPT-RT in my particular case...your mileage may vary considerably.
07:44 PM andypugh: If the latency turns out to be too bad for software stepping (which is inlikely) then there are RTAI kernel packages available that can be installed on Stretch to convert it
07:45 PM Rab: andypugh, oh, thanks! I'll look into that.
07:48 PM andypugh: Rab: www.linuxcnc.org/temp
07:48 PM andypugh: Do you know how to install .deb packages?
07:48 PM Rab: andypugh, I do.
07:48 PM andypugh: Right, so kernel image and headers, reboot, then rtai and linuxcnc.
07:49 PM andypugh: You will end up with a recent LinuxCNC 2.8
07:49 PM andypugh: (But no auto-updates)
07:49 PM Rab: andypugh, great, thank you!
07:50 PM andypugh: Let me know how it goes, those debs were freshly carved today,
07:52 PM _unreal_: ok its a compact DC7600
07:53 PM _unreal_: with a pentium D 3.4ghz
07:54 PM _unreal_: https://support.hp.com/us-en/product/hp-compaq-dc7600-convertible-minitower-pc/472276/document/c00377076
07:54 PM _unreal_: ? my cpu isnt listed
07:54 PM _unreal_: i'm not sure if its 64bit or not
07:54 PM _unreal_: arg...
07:54 PM _unreal_: brb
08:14 PM _unreal_: I dont know which series this freaking cpu is can I cant seem to find a linux disk that will boot
08:20 PM flyback: that's why you already update the bios to latest
08:20 PM flyback: before you swap cpu's
08:20 PM flyback: FFS
08:20 PM _unreal_: I have not ever touched the cpu
08:21 PM flyback: wtf are you using a p4
08:22 PM flyback: they were the most prone era of bad caps
08:22 PM flyback: I can find better pc's hanging from the hairs of my ass
08:24 PM gregcnc: https://www.urbandictionary.com/define.php?term=Covidiot
08:25 PM flyback: im looking forward to it killing everyone
08:40 PM SpeedEvil: We now know what covfefe means.
08:40 PM _unreal_: ?
08:45 PM _unreal_: ok pulled an other pc out that was is messed up
08:46 PM _unreal_: was=one
08:46 PM _unreal_: this one has an intel e2160 and is 64bit ok now I can download
08:48 PM SpeedEvil: :)
09:05 PM Tom_L: andypugh, does the livecd work on preemt also?
09:05 PM Tom_L: to test latency before install
09:33 PM _unreal_: burning disk right now
09:33 PM _unreal_: I'm going to need to get my wireless pendent setup
09:33 PM _unreal_: whb04b-6
09:39 PM Tom_L: https://forum.linuxcnc.org/38-general-linuxcnc-questions/35913-xhc-whb04b-6-linuxcnc-not-working
10:07 PM _unreal_: lcnc is installing now
10:08 PM XXCoder: booom yer on' of us
10:08 PM Tom_L: plan on a bit of a curve with the config
10:08 PM Tom_L: but it will do about anything you need
10:17 PM _unreal_: Thats just phase one :/
10:18 PM _unreal_: hell Ishould go check on the install
10:18 PM _unreal_: was reading the forum on the pendent
10:18 PM Tom_L: there are probably other links for it
10:26 PM _unreal_: ok installed and booted
10:26 PM _unreal_: in the other room but thats just because of lack of room in this room :(
10:26 PM _unreal_: doing a latency test
10:27 PM _unreal_: looks to be 25,000 latency
10:27 PM _unreal_: onboard GPU and only 2gb ram. need to swap the ram
10:27 PM _unreal_: I'll add a GPU when I get around to it
10:27 PM Tom_L: you can fiddle with bios settings and get improvements too
10:28 PM _unreal_: Its an old pentium dual core
10:28 PM Tom_L: it's been a while and i don't quite remember what all to change
10:28 PM Tom_L: maybe not much on that
10:28 PM _unreal_: ya I was going to say :)
10:28 PM _unreal_: only reason I'm using it is because it has a par port
10:29 PM Tom_L: typically you may need newer hardware to run preempt-rt
10:29 PM Tom_L: instead of RTAI
10:29 PM _unreal_: I have a core 2 duo but the board has an empty header for par port :(
10:29 PM Tom_L: may not matter if you're gonna use an ethernet mesa card
10:30 PM Tom_L: to use ethernet though you need to run preempt-rt
10:30 PM Tom_L: which is what that stretch build is
10:30 PM _unreal_: patch? or install wheezy?
10:31 PM _unreal_: ?
10:31 PM Tom_L: for what?
10:31 PM _unreal_: so the streach is preempt-rt
10:31 PM Tom_L: yes
10:31 PM Tom_L: that iso is anyway
10:31 PM _unreal_: Debian Stretch, the 4.9.x RT-PREEMPT
10:31 PM nvz: Tom_L: are you suggesting that works with core2 machines?
10:31 PM _unreal_: linuxcnc-stretch-uspace-amd64-r13.iso
10:32 PM Tom_L: nvz, no
10:32 PM Tom_L: i'm not sure
10:32 PM _unreal_: ?
10:32 PM Tom_L: _unreal_, yeah i've loaded that on my test machine
10:33 PM nvz: I need to do more testing, but I have a Dell OPti 780 SFF with a dedicated graphics card.. and the latency tests seemed rather high
10:33 PM nvz: using the wheezy one that is
10:33 PM skunkworks: that is what I loaded on my current laptop.. ;)
10:34 PM Tom_L: pcw_home would have a better idea what works on core2
10:34 PM skunkworks: rt-preempt seems to like newer hardwaer
10:34 PM skunkworks: hardware even
