01:18 PM CaptHindsight: SpeedEvil: ever work with the APT language or its derivatives? https://en.wikipedia.org/wiki/APT_(programming_language)
01:18 PM CaptHindsight: https://en.wikipedia.org/wiki/EXAPT
01:19 PM CaptHindsight: https://www.emerald.com/insight/content/doi/10.1108/eb004501/full/html
01:19 PM CaptHindsight: developed in at the University of Edinburgh School of Informatics
01:22 PM CaptHindsight: http://aptos.sourceforge.net/
01:22 PM CaptHindsight: CAM before GUI's
01:32 PM CaptHindsight: http://www.vagrearg.org/content/gcmc G-Code Meta Compiler
01:37 PM JT-Shop: time to make a few chips I think
01:37 PM Tom_L: past time to eat a few
01:39 PM Tom_L: question is, are they wood or metal?
01:39 PM jdh: or potato
01:39 PM JT-Shop: these will be steel and the BB ribs will go on the grill shortly
01:40 PM CaptHindsight: Tom_L: did you get rain or snow the past couple days?
01:40 PM Tom_L: rain
01:40 PM Tom_L: but it was pretty chilly
01:41 PM CaptHindsight: there is a new RTAI kernel with the intel and nvidia drivers back in it
01:41 PM CaptHindsight: went from rain 60F to 23 last night and flurries
01:41 PM Tom_L: around 30ish here for the low i think
01:43 PM CaptHindsight: don't know if they will stop and harass if you have 2 people in a car starting later
01:44 PM CaptHindsight: practicing the 6ft rule means having any passenger in the back of the truck
01:44 PM CaptHindsight: which they tend to frown on
01:47 PM Tom_L: so does closing the borders mean the tunnels too?
01:48 PM Jymmm: Tom_L: Pfff, of course not =)
01:48 PM CaptHindsight: I'm really interested in seeing the numbers from Mexico in a few months since they are deciding to do very little
01:48 PM Jymmm: But, what is the infected count in MX vs US ?
01:49 PM CaptHindsight: morbid but interesting comparison
01:49 PM Tom_L: doubt you get accurate numbers
01:49 PM Jymmm: Morbid how?
01:49 PM CaptHindsight: comparing death rates
01:50 PM Jymmm: I said INGECTED, not death
01:50 PM Jymmm: infected*
01:50 PM CaptHindsight: nothing was directed at you
01:50 PM Jymmm: oh
01:50 PM CaptHindsight: I was referring to deaths
01:51 PM Jymmm: CaptHindsight: Quercetin Dihydrate to transport zinc into cell walls https://www.sciencedirect.com/topics/neuroscience/quercetin
01:52 PM Jymmm: https://www.amazon.com/BulkSupplements-Quercetin-Dihydrate-Powder-Grams/dp/B00GW1TVWE
01:56 PM pcw_home: Unfortunately the count doesn't mean much, just the second derivative
01:57 PM Jymmm: pcw_home: Hey, how are you doing? Been thinking about ya
01:57 PM pcw_home: sheltering...
01:58 PM Jymmm: pcw_home: stocked up on essencials?
01:58 PM pcw_home: Yeah never really been an issue
01:59 PM Jymmm: pcw_home: Shelves are kinda bare here, vendors are only able to half fill orders
02:00 PM Jymmm: pcw_home: buy you have livestock too
02:00 PM pcw_home: My wife has always stocked lots of essentials so we are fine
02:01 PM SpeedEvil: CaptHindsight: no
02:01 PM Jymmm: pcw_home: cool, good to hear =)
02:02 PM CaptHindsight: many shelves here are empty by the afternoon, they restock every morning
02:03 PM CaptHindsight: odd site in the west in 2020, reminds me of the cold war films of the east or the US during the depression (1930's)
02:04 PM Jymmm: Yeah, I took pics of the empty shelves too
02:04 PM Javabean: lots of people are, but to be fair... its a fucking crazy sight to see
02:05 PM Jymmm: But, I did figure out the whole No TP thing
02:05 PM skunkworks: idiots?
02:05 PM CaptHindsight: people in line yesterday were joking about people with too few items as they were "hoarding" wrong
02:07 PM Jymmm: lol
02:15 PM Tom_L: almost as eerie as 9-12
02:15 PM Tom_L: and the 'no fly zones'
02:15 PM Tom_L: was exceptionally quiet here
02:38 PM jymmmm: skunkworks: no no, I mean the whole 1800's TP modernized
02:39 PM jymmmm: Back then each person had their own nail and rag in the outhouse, they they were responsable for.
02:41 PM jymmmm: Today's equiv.... one bucket full of clean rags (cut from old towels?), and a soiled bucket. Then just throw them into the washer just like you would cloth diapers.
03:49 PM Jymmm: Hi Lawernce
04:44 PM ve7it: Jymmm, good afternoon... wish I had built that bunker!
04:45 PM Jymmm: ve7it: Did oyu know, a potato in your bunker vent pipe defeats it all =?
04:45 PM ve7it: sounds like fun... fill bunker with propane... flick ur bic... instant potato gun
04:46 PM ve7it: ( do not try this at home.... a public service announcement )
04:49 PM Jymmm: ot DO TRY THIS AT HOME =)
04:54 PM Deejay: gn8
05:32 PM _unreal_: Hi alll
05:32 PM _unreal_: ve7it, what ever your talking about just bumped to the top of my bucket list
05:33 PM _unreal_: hay look ma I'm a human potato in a potato gun
05:36 PM * SpeedEvil has lost a bandsaw.
05:36 PM _unreal_: ?
05:36 PM SpeedEvil: I know I had it before I tidied up.
05:36 PM _unreal_: ??
05:36 PM SpeedEvil: Portaband type thing I wanted to use for cutting threaded rod.
05:37 PM _unreal_: ok...
05:37 PM _unreal_: heh I saw a battery powered millwaki one I'd love to have portaband
05:37 PM _unreal_: I own two bandsaws
05:37 PM _unreal_: a 93" grizzly big old fucker
05:37 PM _unreal_: and a delta triband
05:38 PM SpeedEvil: I keep thinking of DIY.
05:38 PM _unreal_: ?
05:38 PM _unreal_: diy bandsaw?
05:38 PM SpeedEvil: portaband type thing battery
05:38 PM SpeedEvil: (got heavy mains one)
05:38 PM _unreal_: hum
05:39 PM _unreal_: ! SHIT now I know what I could have grabbed from work... my 8" 1/4" drill bits
05:39 PM _unreal_: damn it
05:40 PM p0g0: _unreal_, folks make band saw wood mills, I did a bit of work on one a couple of decades Back- the crowned rollers and guides are available as a kit.
05:40 PM _unreal_: I need to drill mounting holes in my 3 servo motor controllers I built
05:40 PM _unreal_: from ve7it's designs
05:40 PM _unreal_: hum
05:40 PM _unreal_: I stil say its not worth DIY'ing a band saw
05:41 PM _unreal_: the $ money and effort will exceed any average bandsaw purchase price
05:41 PM _unreal_: now if one lives in a remote area where getting tools is a joking conversation thats a different story
05:41 PM _unreal_: or country
05:41 PM p0g0: Well, there are a lot of shop scale band saws
05:42 PM p0g0: viz: http://cookssaw.com/
05:42 PM p0g0: They'll sell the rollers and guides, for example.
05:43 PM _unreal_: ok? dont know what i'm looking for on that page so I 'll take your word for it
05:43 PM p0g0: https://cookssaw.com/parts/band-wheels/
05:44 PM p0g0: as an example
05:44 PM p0g0: I'm not encouraging you to build one, just saying some folks do.
05:45 PM _unreal_: lol very expesive
05:45 PM _unreal_: just for the wheel
05:45 PM _unreal_: ONE wheel eve
05:45 PM _unreal_: even
05:45 PM SpeedEvil: I was more thinking 100mm blade wheels.
05:45 PM p0g0: A good production band saw mill is pricy,
05:46 PM _unreal_: I'm not saying its dead. but I'm going to gladly say some areas of DIY are really diy'ing IMO
05:47 PM _unreal_: not sure what I want to work on right now
05:47 PM _unreal_: I need to drill mouting holes in my 3 motor controller pre heat sink heat sinks
05:47 PM _unreal_: so they can later be mounted to the main heat sink
05:47 PM _unreal_: Ineed to drill mounting holes in the HEAT sink
05:48 PM _unreal_: That would make it so I can mount my motor controllers
05:48 PM _unreal_: I need to get my PSU put together
05:48 PM _unreal_: and work on the machine wiring
06:05 PM _unreal_: ?
06:05 PM _unreal_: so quiet
07:01 PM gregcnc: social distancing vs physical distancing?
07:01 PM XXCoder: hey
07:03 PM _unreal_: Hay baby
07:03 PM gregcnc: i should have ordered some tooling I wanted during the week.
07:03 PM _unreal_: hum
07:04 PM gregcnc: saw my neighbor come home with lunch and.....
07:04 PM gregcnc: a rifle
07:05 PM XXCoder: oh just a quick lunch and murder pickup
07:06 PM gregcnc: they releasing prisoners in WA?
07:06 PM _unreal_: fuck with me I dare you "ching ching"
07:06 PM _unreal_: gregcnc, libs trying to push agenda. NOT likely
07:06 PM _unreal_: infact prisoners from what I hear DONT want to leave and be contaminated
07:07 PM Javabean: gregcnc: got some sauce for that?
07:08 PM gregcnc: they are releasing low risk here
07:09 PM CaptHindsight: are shooting ranges considered "essential" businesses now?
07:09 PM gregcnc: yes, just read something
07:09 PM gregcnc: though our seems to have closed
07:09 PM XXCoder: i laugh each time someone says "liberal agenda"
07:10 PM CaptHindsight: yeah, what if we make the world a better place for no reason at all?
07:11 PM gregcnc: more improtantly liquor stores are also essential
07:13 PM gregcnc: is CDC really just not going to post updates on their site over the weekend?
07:13 PM XXCoder: h0ly crap myfordboy failed a pour
07:13 PM XXCoder: bottom belw out
07:13 PM XXCoder: blew
07:14 PM CaptHindsight: https://solar-power-now.com/wp-content/uploads/2014/08/betterworldfornothing.jpg
07:14 PM XXCoder: capt yeah one of my favorites
07:14 PM CaptHindsight: mine as well
07:15 PM XXCoder: https://youtu.be/P7LpstatxhQ
07:18 PM gregcnc: will fall season of TV/movies be dry?
07:19 PM CaptHindsight: yeah, could be a really late fall season or no new shows
07:19 PM XXCoder: whats washington state without rain?
07:19 PM XXCoder: nowashington thats what
07:19 PM CaptHindsight: rim shot
07:19 PM XXCoder: its been WEEKS of no rain wow
07:20 PM Javabean: you can have a "bud dum" but no "tiss"
07:22 PM CaptHindsight: gregcnc: where does the NYT get their official numbers then?
07:22 PM CaptHindsight: https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/cases-in-us.html This page will be updated regularly at noon Mondays through Fridays. Numbers close out at 4 p.m. the day before reporting.
07:23 PM gregcnc: I would guess state sites
07:23 PM CaptHindsight: or the AP https://apnews.com/
07:24 PM CaptHindsight: :p are these considered fake?
07:27 PM gregcnc: https://coronavirus.health.ny.gov/county-county-breakdown-positive-cases
07:28 PM gregcnc: 3500 more than yesterday
07:29 PM Javabean: https://www.worldometers.info/coronavirus/ https://gisanddata.maps.arcgis.com/apps/opsdashboard/index.html#/bda7594740fd40299423467b48e9ecf6
07:30 PM pcw_home: We are now the top below Italy and China in cases
07:30 PM pcw_home: probably surpass Italy is less than a week
07:31 PM pcw_home: log(cases) not looking good
07:31 PM CaptHindsight: are we are hardly testing yet
07:32 PM CaptHindsight: and if the new recommendation here is to only test where the treatment will drastically change, then the test numbers aren't apples to apples
07:33 PM CaptHindsight: maybe the death rate number will be accurate and comparable
07:33 PM pcw_home: the recent up-tic might reflect more testing
07:34 PM pcw_home: but its gone from about 10X per 8 days to 10x per 6 days if you extrapolate
07:34 PM gregcnc: yeah, I read that. not enough tests kits around here
07:35 PM pcw_home: Italy looks much better
07:35 PM Javabean: https://kvia.com/coronavirus/2020/03/19/what-does-it-takes-to-be-tested-for-the-coronavirus-in-el-paso-heres-the-answer/
07:37 PM XXCoder: 303k total so far. nuts
07:37 PM XXCoder: almost 13k deaths
07:37 PM XXCoder: usa now 4th worst hit site
07:38 PM pcw_home: USA is 3rd in reported cases
07:38 PM pcw_home: Just beat Spain...
07:39 PM gregcnc: Population italy 60M, USA 320M
07:39 PM pcw_home: Yep, not good
07:39 PM XXCoder: oh youre right
07:39 PM gregcnc: so how did China really fair with 1.4B
07:39 PM XXCoder: i forgot to refresh from few hours ago
07:39 PM XXCoder: gregcnc: repressive goverment
07:39 PM XXCoder: one of VERY few postives about it
07:40 PM Javabean: the ability to lie their asses off with no repercussions?
07:40 PM pcw_home: Korea did really well
07:40 PM XXCoder: im surpised india wasnt really hit either
07:40 PM CaptHindsight: also Japan and Taiwan
07:40 PM pcw_home: Juts wait...
07:40 PM XXCoder: it has 3 most dense areas in top 5
07:40 PM CaptHindsight: india is just behind
07:41 PM XXCoder: japan culture is very good on social distancing and mask wearing, as well as protecting others from themselves as well as protecting themselves
07:41 PM gregcnc: I think it comes down to the Asian countries experience with the previous diseases. the rest of the world just isn't prepared
07:41 PM CaptHindsight: Taiwan learned from SARS-1
07:41 PM pcw_home: 3rd world countries will likely be hit the hardest though being late may help with better treatments
07:43 PM CaptHindsight: good time to vacation in the Yukon
07:43 PM XXCoder: north pole
07:43 PM CaptHindsight: stay at your remote cabin
07:44 PM CaptHindsight: positive spin "trump was just trying to beat China with highest score!"
07:47 PM pcw_home: MAGA!
07:47 PM XXCoder: man, again, get away!
07:47 PM pcw_home: we will beat China in 2 weeks
07:47 PM pcw_home: maybe less
07:48 PM XXCoder: flornia beach will help!
07:48 PM XXCoder: huge crowds
07:48 PM pcw_home: from all over the US, going back to all over the US
07:49 PM gregcnc: yeah that will be great
07:53 PM XXCoder: "file dont lie" lol
07:53 PM XXCoder: man I love this old tony
07:54 PM XXCoder: https://youtu.be/ST3yf-H51Hg
09:02 PM -!- #linuxcnc mode set to +v by ChanServ
09:18 PM veegee: So MIG welding is pretty much the same as stick welding but with a shielding gas and it feeds the wire for you
09:19 PM XXCoder: from what I saw in various channels and expecially this old tony yeah
09:25 PM Tom_L: veegee, sounds about right
09:25 PM veegee: Ok great, then I don't care for it
09:25 PM veegee: Looks like I'm going to be getting a TIG welder because TIG and stick is all that matters
09:26 PM Tom_L: i got a mig welder
09:26 PM Tom_L: tig would be nice
09:33 PM rue_mohr: tig can be annoying
09:33 PM rue_mohr: you need to set up a grinder right beside ya
09:34 PM rue_mohr: makes nice welds tho
09:34 PM rue_mohr: I'v never done anything heavy in tig
09:37 PM Tom_L: i've never needed one yet
09:42 PM veegee: Yeah I don't mind cleaning the workpiece. I don't fabricate anything in quantity. My stuff is entirely for hobby purposes. I care entirely about quality, not quantity
09:42 PM veegee: Unrelated, but who makes permanent magnet AC motors?
09:43 PM Tom_L: i did my mill with a mig
09:43 PM veegee: Baldor has a nice online catalog of their induction motors, but I can't seem to find anything for permanent magnet synchronous AC motors
09:44 PM veegee: Damn, only found their catalog for up to 3hp models. Was hoping for a 10-15hp one
09:45 PM Javabean: probably be cheaper to build one that size by hand... the shipping alone might be more than the sell price
09:46 PM veegee: wow yeah they are insanely expensive
09:47 PM veegee: ok I guess totally not worth it for the efficiency gains
09:49 PM veegee: Also what the hell, their 2hp PMAC motor is 87.5% efficient and their 2hp induction motor is 86.5% efficient...
09:49 PM veegee: PMAC should be far more efficient than that
09:50 PM Javabean: there could be patents in their way
09:53 PM XXCoder: tom saw tony;'s video about heat treatment furance. amazing
09:53 PM XXCoder: it makes hardening and annealing much easier
10:00 PM _unreal_: are there any low cost auto tool change spindles?
10:03 PM XXCoder: in what sense of low cost?
10:03 PM XXCoder: $10,000 would be insanely cheap for large production machine for example
10:05 PM _unreal_: wondering if there are any small spindles that are available
10:09 PM Tom_L: https://cadcamcadcam.com/toolchanger.aspx
10:11 PM XXCoder: not bad really
10:11 PM XXCoder: looks like same taper type as office mill
10:11 PM XXCoder: dont buy office mill, haas btw
10:12 PM XXCoder: unless youre running it like 10 times a year
10:14 PM XXCoder: or have very strict maintance that cleans chips off ways and voids in machine (like rear column)
10:48 PM CaptHindsight: _unreal_: https://www.automationtechnologiesinc.com/products-page/cnc-atc-spindles/
10:49 PM XXCoder: thats at small production level
10:49 PM XXCoder: dont think unreal operates at that level
10:49 PM CaptHindsight: https://www.aliexpress.com/item/32397698428.html?src=google&src=google&albch=shopping&acnt=768-202-3196&isdl=y&aff_short_key=UneMJZVf&slnk=&plac=&mtctp=&albbt=Google_7_shopping&aff_platform=google&&albcp=9603941227&albag=96253190102&trgt=299423776478&crea=en32397698428&netw=g&device=c&albpg=299423776478&albpd=en32397698428&gclid=EAIaIQobChMIi_WwrJat6AIVYZJbCh3iYwogEAQYASABEgJ9WvD_BwE&gclsrc=aw.ds
10:49 PM XXCoder: wonder if theres such thing as sub-500 atc
10:49 PM CaptHindsight: US $459
10:49 PM XXCoder: it does. interesting
10:49 PM XXCoder: bt30 definitely small enough for his machine
10:50 PM XXCoder: no idea how to design to use it though lol
10:50 PM CaptHindsight: https://cdn.carbuzz.com/gallery-images/original/106000/100/106148.jpg
10:50 PM XXCoder: what about that ferrani?
10:50 PM XXCoder: ;)
10:51 PM CaptHindsight: cheap ferrari, like cheap spindles
10:52 PM XXCoder: checked. yep bt30 is same as my toolholder I bought to demonstate spindle stuff to people
10:52 PM XXCoder: https://www.aliexpress.com/item/4000205005744.html
10:52 PM XXCoder: though no cat20 atc?
10:52 PM XXCoder: tiny ones
10:53 PM XXCoder: iso20
10:54 PM XXCoder: https://www.aliexpress.com/item/32944532381.html more money lol
11:36 PM veegee: I was looking into a heat treatment furnace too
11:36 PM veegee: you can make one yourself
11:36 PM XXCoder: i suppose bt im not much into diyer
11:36 PM veegee: All you need is some NiCr wire and some fire brick
11:37 PM veegee: And a power supply with temperature feedback
11:37 PM veegee: Could also go the propane BBQ route with a thermal regulator of some sort, but ovens in general are very easy to make
11:37 PM veegee: Orrrr stick your normal oven into "self cleaning" mode
11:38 PM XXCoder: lol
11:38 PM XXCoder: well wonder if theres pid stuff
11:38 PM veegee: That'll make it go to 500ÂșC which is about right for the hardness you want to maintain
11:38 PM _unreal_: That sucked
11:39 PM _unreal_: I'll spare you'all the details. bathroom issue end of story
11:39 PM XXCoder: lol
11:39 PM XXCoder: trying to install a bidet?
11:39 PM veegee: I had a motorcycle accident a few years ago, completely destroyed shoulder joint
11:39 PM veegee: I never use toilet paper because it's a disgusting american habit
11:39 PM veegee: I always use water
11:40 PM veegee: So of course with only one working arm, you can't pour water and clean at the same time
11:40 PM veegee: So I made a bidet with an RV water pump and a bidet head
11:40 PM veegee: I didn't attach it directly to the cold water line because cold water feels horrible squirting right at your butt
11:40 PM XXCoder: bidet is quite cheap
11:41 PM veegee: So I just filled a bucket with warm water and a tad bit of soap as the water source and it worked great
11:41 PM XXCoder: in least ones that dony use power nor hot water
11:41 PM veegee: Also yeah I'm just sitting here laughing at all the dumbass americans hoarding toilet paper
11:41 PM XXCoder: yeah im american and im laughing ass.
11:41 PM XXCoder: *off
11:41 PM veegee: It blows my mind how americans walk around with dirty assholes all day
11:41 PM XXCoder: in least tp dont expire!
11:41 PM veegee: wtf do you use it for? Do you just wipe it dry like that?
11:41 PM XXCoder: no to remove shit
11:42 PM veegee: yea but it doesn't get everything
11:42 PM XXCoder: it doesnt lol
11:42 PM veegee: The rest of the world figured that out and uses water
11:42 PM XXCoder: unless you use so much tp last one dont change color
11:42 PM XXCoder: i dont bother
11:42 PM veegee: and it irritates the anus if you scrub too hard
11:42 PM XXCoder: precisely
11:42 PM veegee: I give my butt a mini shower each time
11:42 PM XXCoder: and my bpdy is getting less and less flexable
11:42 PM XXCoder: i need it now
11:43 PM veegee: not only does it make it super clean, it also gets rid of any sweat and what not
11:43 PM XXCoder: all that dumb tp hoarding did something good though
11:43 PM XXCoder: it finally kicked my ass to buy a bidet
11:43 PM CaptHindsight: come for the CNC, stay for the poop talk :)
11:43 PM XXCoder: yep
11:43 PM veegee: and just recently I learned what "dingleberries" are
11:43 PM CaptHindsight: hey family channel
11:43 PM XXCoder: controller software to crapper controller channel, this channel is for everything
11:43 PM veegee: No they're not a fruit from a tree
11:44 PM veegee: Let's just say they only grow in america where they haven't discovered how to clean themselves properly yet
11:44 PM XXCoder: never had that lol
11:44 PM _unreal_: bunch of shit slingers in here
11:44 PM veegee: Me neither but then again, I use soap/water every day
11:45 PM veegee: if I have no choice, like at the office, I use paper towels moistened with water and light soap
11:45 PM veegee: I know you shouldn't flush those, but fuck the american sewage system. Their fault for designing something for barbarians
11:45 PM veegee: I cannot go about my day with a dirty asshole
11:46 PM veegee: Sorry, end rant
11:46 PM XXCoder: lol
11:46 PM veegee: It just really irritates me how backwards the sanitation in north america is
11:46 PM XXCoder: actually its pretty good here
11:46 PM XXCoder: just not with backends
11:47 PM veegee: yeah that's true
11:47 PM XXCoder: ohh looks good https://youtu.be/x3O6QXyHaCY
11:47 PM XXCoder: zach king
11:52 PM _unreal_: 1am I'm going to bed
