12:02 AM jesseg: Howdy fragalot_
12:05 AM fragalot_: hello
12:05 AM jesseg: How's it going there, fragalot_ ?
12:05 AM fragalot_: can't complain :-) you?
12:05 AM jesseg: Not too bad! Just getting ready to drive 7 hours tomorrow to go camping and fishing with my 77 year old dad and other family friends, yearly camping/fishing event :D
12:06 AM gloops: excellent jesseg
12:07 AM gloops: just had my reminder for fishing license, i might get for a few hours next week sometime
12:08 AM jesseg: CaptHindsight, hazzy-dev helicopters can, I've heard, built up a pretty stout static charge from the air rushing past them
12:09 AM jesseg: but yeah, choppers and wires... fresh pilots need not apply.
12:09 AM fragalot_: there is a reason they typically 'hook' the line to the heli
12:10 AM jesseg: what are those spiral things for?
12:10 AM fragalot_: to stop you getting pregnant
12:10 AM jesseg: yeah actually is that an electrical ponding hook they put on to prevent static shock?
12:10 AM fragalot_: yes
12:11 AM fragalot_: that and capacitive coupling
12:11 AM jesseg: *bonding* not ponding LOL
12:11 AM fragalot_: it ensures the heli is always at the same potential as the line, making it safer to touch
12:11 AM jesseg: yeah
12:11 AM fragalot_: the spiral lines are to stiffen the wire, I think
12:11 AM fragalot_: oh.. vibration damper
12:12 AM fragalot_: says so in the first comment, lol
12:12 AM jesseg: yeah I was wondering if it wasn't some sort of dynamic dampter
12:12 AM jesseg: blah.. damper
12:12 AM fragalot_: credit where credit is due though.. That pilot... damn.
12:14 AM jesseg: yes.... yes...
12:20 AM hazzy-dev: jesseg: your right, helicopters can build up a very significant charge, that is why when they drop a line they drag it on the ground to ground it out
12:22 AM fragalot_: looks like a phoenix knock-off
12:22 AM fragalot_: you should be able to buy 30 "legit" phoenix ones from farnell or similar for the same price as 1000 china ones
12:24 AM fragalot_: jesseg: https://imgur.com/gallery/8NUNsSd <= relevant
12:30 AM jesseg: fragalot_, hahaha uh huh... yup... "I didn't know sand burned. Hey my feet are burning too I better move."
12:30 AM jesseg: -Cameraman
12:31 AM fragalot_: well you can get electrocuted via the ground itself
12:31 AM jesseg: yup
12:31 AM fragalot_: biggest killer too when it comes to lightning strikes
12:31 AM jesseg: more likely if you're standing sideways with your feet across a potential gradient
12:31 AM fragalot_: indeed
12:32 AM jesseg: yeah lightening can have a pretty big gradient, you wouldn't have to be very far off of parallel to get it
12:37 AM gloops: hmm, ive got some fuzzy felt vinyl, wonder if i stick it to mdf, router will cut it - or will tool snarl up the fuzz and rip it off
12:37 AM gloops: and maybe jam the spindle
12:38 AM fragalot_: depends on how sharp the cutter is, but I would expect failure
12:38 AM gloops: straight flute cutter maybe
12:38 AM fragalot_: i'd expect downcut to do better
12:39 AM gloops: downcut maybe shear it of against the wood edge better
01:07 AM CaptHindsight: jesseg: that might only be true with wool or rubber balloon helicopters
01:16 AM jesseg: CaptHindsight, lol yeah maybe. But the guy that told it to me was a power line service helicopter pilot.
01:16 AM jesseg: or maybe the basket worker dood
01:17 AM jesseg: anyway when I was a youngster my family lived by the BPA power lines. And at one point the BPA decided it'd be cool to string fiber optic bundle along the powerline towers to bring modern internet to our little hamlet
01:17 AM jesseg: and when they'd land the chopper and have lunch I'd run out to the field and talk to them :D
01:18 AM jesseg: it was a cute little chopper with no tail rotor -- it had a hollow tail tube and it blew air out and it had a swiveling air vent on the end that would shoot air whichever way the pilot wanted
01:19 AM jesseg: I guess that's nice for line work because it won't chop up the power lines if it touches the tail end :P
01:19 AM CaptHindsight: less to get tangled
01:19 AM CaptHindsight: thrust vectoring copter
01:20 AM jesseg: yeah
01:20 AM CaptHindsight: they need those cars in Blade Runner
01:20 AM CaptHindsight: and the skin jobs could do the dangerous work
01:20 AM jesseg: I wonder what model of copter that was...
01:21 AM fragalot_: GDPR has come into effect today
01:21 AM fragalot_: hopefully that will end the flood of emails about it
01:22 AM CaptHindsight: is that some new German thing?
01:22 AM CaptHindsight: like DDR?
01:22 AM fragalot_: lol
01:22 AM fragalot_: european data protection act
01:22 AM fragalot_: it is no longer allowed to store any data about a person or account for longer than necessary
01:22 AM CaptHindsight: we have right to be remembered
01:23 AM fragalot_: or without express permission of said user
01:23 AM CaptHindsight: in fact they want to reduce the size of data bits to so small they can store more stuff here
01:23 AM CaptHindsight: they want <1nm^2 per bit
01:24 AM fragalot_: https://www.dataiq.co.uk/blog/summary-eu-general-data-protection-regulation
01:24 AM CaptHindsight: it's ok, since we will just store the data for the EU over here
01:24 AM fragalot_: well, no you're not
01:25 AM CaptHindsight: bet they will :)
01:25 AM fragalot_: they'll try
01:26 AM CaptHindsight: laws are for the little people
01:26 AM fragalot_: but any business active in the EU, or dealing with EU citizen data, which does not comply and is found guilty of cross-border data transfers, will be served a penalty of €20m, or 4% of the entities global revenue
01:26 AM CaptHindsight: spy business?
01:26 AM CaptHindsight: oh for small businesses sure
01:26 AM jesseg: cool the new ambulance chaser cottage business. No need to go after music copyright violators anymore :D
01:27 AM CaptHindsight: i was talking about guberments data storage on everyone
01:28 AM fragalot_: CaptHindsight: even there the data may only be stored for the absolute minimum time required to process it down to what they need to know
01:28 AM fragalot_: so no indefinite records
01:30 AM fragalot_: the main thing really is that there is finally some sanctionable power there
01:30 AM fragalot_: before all they could do is say "stop that!"
01:30 AM jesseg: good night folks
01:32 AM CaptHindsight: fragalot_: do you think it will cut down on spam email sent to the EU?
02:39 AM Deejay: moin
04:27 AM RyanS: If money were no object would you still build a CNC machine? It's not really my idea of fun (at least not electronics or coding) just can't afford to buy one
04:38 AM Loetmichel: sure. its fun to make one. I sitll have a project going (for years now) to make a CNC 6040-sized router for less than 1000,- eur.
04:38 AM Loetmichel: so far it works out ;)
04:39 AM Spirit532 is now known as Guest44005
04:39 AM Spirit532_ is now known as Spirit532
04:40 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=8875
04:40 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=8884
04:41 AM RyanS: one of those cutting tool vending machines stocked by the supplier would be great. and racks and racks of fasteners
04:41 AM Loetmichel: https://www.youtube.com/watch?v=mAnwbQ4gk9M
04:41 AM Loetmichel: ... thats the base for it.
04:43 AM RyanS: my 'Lego set' would be made by THK or Bosch... although it's no challenge if you don't have to hunt for components
04:44 AM Loetmichel: indeed, thinking about how to use "not meant for the job" things to do it is half the fun ;)
04:45 AM RyanS: a full stock of threaded rod, nuts and drawer slides then
04:47 AM Loetmichel: not drawer slides. they are crap
04:47 AM syyl: i guess my lego set would be steel square tubing and a tig welder ;)
04:47 AM Loetmichel: i use ground hardened smooth rods (16mm) and ball bearings as a rider.
04:48 AM syyl: i built way to much stuff with aluminium extrusion to hate that stuff ;)
04:48 AM gloops: washing machine drawer bits are more robust
04:48 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=347
04:48 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=344
04:48 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=335
04:49 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=359
04:49 AM RyanS: is aluminium extrusion crap or just sick of it?
04:49 AM Loetmichel: ... odler design of mine in 4mm thick glass fibre reinforced epoxy ("FR4")
04:49 AM Loetmichel: its not hard enough
04:49 AM syyl: its nice for lab stands, tables, handling-systems and stuff like that
04:49 AM Loetmichel: a ball bearing outer race has "walked" a flat into that in no time
04:49 AM syyl: but i find it annoying to work with
04:50 AM Loetmichel: or did you mean for a frame?
04:50 AM Loetmichel: for a frame it has the disadvantage of being ALWAYS bent.
04:50 AM Loetmichel: (extrusion CANT produce internal stress free STRAIGHT bars)
04:51 AM rmu: extrusions are usually flat enough for the kind of machine you want to build out of them
04:52 AM gloops: someone on facebook built a big router recently with extrusion gantry - works ok but first complaint - why is it giving rough finish?
04:52 AM rmu: you could fill the extrusion with some kind of epoxy concrete
04:52 AM gloops: my hunch - no weight
04:52 AM syyl: it wont change the stiffness much
04:52 AM syyl: all the material you fill in is close to the central axis of the profile
04:53 AM syyl: large cross section creates stiffness, not mass.
04:53 AM gloops: it adds some mass though, soaks up some vibes
04:53 AM syyl: not necessary
04:53 AM syyl: it will shift the natural vibration frequency
04:53 AM rmu: there are (expensive) extrusions with large cross-sections
04:54 AM rmu: "large"
04:54 AM syyl: and in the worst cases you could make it vibrate easier :D
04:54 AM syyl: yes, sure, there are 100x100mm profiles
04:54 AM gloops: well, no vibration issues with old cast iron machines
04:54 AM syyl: yes
04:54 AM syyl: because they are well made ;)
04:54 AM RyanS: although it doesn't take a lot to mig weld to a decent level, it seems like knowing how to control distortion is half the skill. perhaps that's why many people don't weld diy machines
04:54 AM gloops: because they are heavy
04:54 AM syyl: the connecting surfaces between mating parts are generally machined and scraped
04:55 AM gloops: make the same design with hollow ally - not the same machine at all
04:55 AM syyl: that increases stiffness way more than just adding mass
04:55 AM XXCoder: hey linuxcnc guys
04:55 AM syyl: i agree that it is a factor, gloops :D
04:55 AM syyl: definetly!
04:55 AM SpeedEvil: Loetmichel: I've wondered about cheap air bearings as a hack to allow crappy ways.
04:56 AM syyl: letalone the fact that steel/cast is about three times stiffer than aluminium
04:56 AM Loetmichel: RyanS: mig welding a frame for a CNC router is easy. geting it stress free prior to milling the linear slide mounts is the tricky part
04:56 AM syyl: no its easy :D
04:56 AM Loetmichel: SpeedEvil: air bearings need air.
04:56 AM SpeedEvil: syyl: Which only matters until the aluminium is 1.5* as thick or so.
04:56 AM gloops: the material is stiffer in itself, shape trumps material though, the ally sections can be incredibly stiff
04:56 AM SpeedEvil: syyl: (barring local deformation)
04:56 AM syyl: every heat threater will happily stress releaf a weldmend for you
04:57 AM Loetmichel: someone who cheaps out on a cnc mill is not likely to have compressed air OR the willingless to provide and maintain it "just for the CNC" ;)
04:57 AM syyl: its about a buck per kg of material
04:57 AM SpeedEvil: Even wood gets stiffer than steel at 4* the thickness
04:57 AM syyl: hu?
04:57 AM syyl: and when i make the steel 4x the thickness?
04:57 AM syyl: thats a weird comparisation.
04:57 AM SpeedEvil: Sure.
04:58 AM rmu: in theorey you can make the aluminium extrusion have larger cross section than steel part with same dimensions
04:58 AM rmu: same weight
04:58 AM Loetmichel: SpeedEvil: there is a reason why all of my CNC machines have marine plywood and "box sections" as a general design
04:58 AM rmu: in theory it could improve stiffness
04:58 AM Loetmichel: its INCREDIBILY stiff
04:58 AM rmu: like in bicycle frames
04:58 AM syyl: there can be reasons to do that, rmu
04:59 AM RyanS: so if I want a lightweight plasma gantry, am I better off with thick wall SHS aluminum than t-slot profile extrusion
04:59 AM syyl: i would use a large cross section, thin walles steel square tube ;)
04:59 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=11205&g2_imageViewsIndex=1 <- lighweight and insanely stiff
05:00 AM XXCoder: Loetmichel: ya I usually call it boxed cnc design lol
05:00 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=11172&g2_imageViewsIndex=1 <. gantry is missing the back panel and some internal cross braces)
05:00 AM XXCoder: it was my orginial plan to make one
05:00 AM syyl: steel allows to build very lightweight structures..
05:00 AM syyl: if there is not only material thrown at the design ;)
05:00 AM rmu: Loetmichel: the problem with wood is dimensional stability
05:00 AM syyl: or lack off ;)
05:00 AM Loetmichel: rmu: not with marine plywood
05:01 AM XXCoder: plywood is less sensive even if not marine type
05:01 AM Loetmichel: its "waterproof", doesent shrink or expand with humidity change
05:01 AM Loetmichel: also its cross layered taking out the "uneven" shrink/expand with temperature
05:01 AM rmu: Loetmichel: depends what kind of accuracy you want, but even this "waterproof" stuff moves way more than aluminium
05:01 AM Loetmichel: not by much
05:02 AM RyanS: syyl: it doesn't have radius on aluminum so you could have a reference edg. can't really tap thin wall steel
05:02 AM Loetmichel: and usually 1/100mm accuracy in a somewhat temperature and humidity controlled basement is perfectly achiveable
05:02 AM RyanS: edge*
05:02 AM syyl: i doubt that.
05:03 AM syyl: we struggle with 1/100mm on real machines from time to time ;)
05:03 AM rmu: Loetmichel: 1/100mm per se doesn't say much.... 1/100mm over 1m would
05:03 AM Loetmichel: you can dount it all day. tried it multiple times. only in alu and plastics though
05:03 AM gloops: id go with the t-slot, to save work
05:03 AM Loetmichel: doubt
05:04 AM syyl: measured with calipers?
05:04 AM Loetmichel: rmu: i made 4mm FR4 panels for model planes on THAT machine and they were within 1/100mm over 808mm lenght. good ebough for you?
05:04 AM Loetmichel: 800mm
05:05 AM syyl: checked on a cmm?
05:05 AM syyl: bould statement ;)
05:05 AM rmu: i can measure up to 50mm or so with +-0,01mm if i'm lucky
05:05 AM Loetmichel: syyl: big digital calipers, yes.
05:05 AM syyl: ok, then its not 1/100 ;)
05:05 AM rmu: 1/100mm over 800mm length: i doubt it, not with steppers and acme-thread
05:05 AM Loetmichel: as you whish to belive.
05:05 AM syyl: our grinderhands at work would not garantee you 1/100mm over that length
05:05 AM syyl: or the wire-edm guys
05:06 AM syyl: or me, running a mill :D
05:06 AM Loetmichel: i dont deal with absolutists that cant deal with others achiving what they cant and say "it cant be".
05:06 AM syyl: if you tell me that you measure by 0,01mm over a distance of 800mm with calipers
05:07 AM Loetmichel: and i didnt say "guranteed" i said "achievable"
05:07 AM syyl: any reasonable person will doubt that
05:07 AM rmu: even temperature would matter a lot, we are talking 10ppm
05:07 AM RyanS: I just checked a structural steel tech guide, a 1m piece has a 2.5mm twist tolerance and 0.5mm concavity on the profile... that's bad for machine building
05:07 AM RyanS: if no milling afterwards
05:07 AM syyl: yep :D
05:08 AM syyl: a welded structure will always need machining
05:08 AM syyl: or other tricks like shimming/glueing ground flat steel to it
05:08 AM XXCoder: hand file it all down flat lol
05:08 AM syyl: :D
05:08 AM rmu: 1°C difference will amount to about 1/100 on 800mm with FR4 (ballpark figure)
05:09 AM syyl: thats about the same for steel
05:09 AM syyl: we say 1°K over 1000mm is 0,01mm
05:09 AM Loetmichel: XXCoder: if yopu are good with a file: would work
05:09 AM Loetmichel: if you are bad: wouldnt ;)
05:09 AM Loetmichel: rmu: indeed
05:10 AM XXCoder: Loetmichel: and have oceans of time lol
05:10 AM Loetmichel: XXCoder: yes
05:11 AM Loetmichel: syyl could probably say something about that, he is known as the "scraper god" around the german channel...
05:11 AM Loetmichel: takes about as long as filing if not longer ;)
05:11 AM syyl: faster
05:11 AM syyl: and that is something that has been done in building machinery
05:12 AM syyl: after welding/stress reliefing,/machining
05:12 AM syyl: scraping the mounting surfaces seriously true
05:12 AM RyanS: hmm, so if I have a welded table plasma, gantry will be bolted, use milled gussets etc, I don't understand why some people insist on linear rails, if plasma isn't a particularly accurate process anyway
05:12 AM syyl: i would not do it :D
05:12 AM miss0r: What are we talking about here?
05:13 AM RyanS: they don't mill the surfaces usually
05:14 AM Loetmichel: miss0r: mounting surfaces for linear rails on selfbuilt CNC frames
05:14 AM miss0r: Indeed. For a plasma CNC, milled surfaces are perfectly fine :]
05:15 AM SpeedEvil: ex-bandsaw even
05:15 AM miss0r: then ground and lapped :P
05:15 AM rmu: hehe
05:16 AM syyl: lapped is reasonable
05:16 AM rmu: most important thing is large enough reference surface
05:16 AM syyl: mating surfaces scraped and lapped?
05:16 AM miss0r: syyl: Not only is it reasonable, it is a must :P
05:16 AM syyl: \ø/
05:16 AM syyl: finaly
05:16 AM syyl: :D
05:16 AM RyanS: i'm leaning towards V groove rollers, i cant fit a gantry in my mill..
05:16 AM XXCoder: flatness with tol of +- 100 atoms ;)
05:17 AM miss0r: XXCoder: Get back to me, when you are talking about real precision ;D
05:17 AM syyl: i guess for a plasma table some wire is good enough for reference
05:17 AM XXCoder: you can do better than 100 atoms +- tol? dang you the precision god
05:17 AM miss0r: :þ
05:17 AM miss0r: I absolutly cannot. I just like to talk about it ;)
05:17 AM XXCoder: :)
05:18 AM miss0r: My machine park had its prime around 40 years ago... so eh
05:18 AM RyanS: how about diamond machining (?) where the surface is a mirror
05:18 AM syyl: boggles the mind :D
05:18 AM syyl: next step: diamond turning optical surfaces?
05:18 AM Loetmichel: what was that joke with the americans making what they think the "thinnest wire in existence" and pridly sending it to different institutes around the world...
05:19 AM Loetmichel: ... the russians: "why did you sent us an empty packet?"
05:19 AM miss0r: syyl: I've seen a few videos of something simular... I just stare at it in disbelief... drueling even
05:19 AM Loetmichel: the germans "we measured it, its indeed very thin"
05:19 AM syyl: there is a viedeo going round with an airbearing spindle on a moore-platform
05:19 AM syyl: turning mirrorlike copperparts
05:19 AM syyl: completely insane
05:19 AM RyanS: they split the atom in the 30s, you can do better than 100 atoms
05:19 AM miss0r: yeah, i've seen it
05:20 AM miss0r: hehehe
05:20 AM Loetmichel: the japanese: "we didnt know what to do with it so we drilled a hole in one end and cut a thread on the other!"
05:20 AM miss0r: Loetmichel: hehe nice
05:20 AM syyl: still annoyed that I could not buy the moore jiggrinder from work ;)
05:20 AM RyanS: the Russians probably drilled it too
05:20 AM syyl: (correction, could have bought, but no room... :*( )
05:20 AM XXCoder: syyl: got link?
05:21 AM syyl: the video?
05:21 AM miss0r: syyl: hehe, welcome to my world. I onlt have a homemade spindle with a waaay too big motor, to use as a tool post grinder ;)
05:21 AM XXCoder: yeah
05:21 AM Loetmichel: RyanS: i did make that up. there were even more countrys, couldnt remember the responses though
05:21 AM Loetmichel: only remebered the punchline.
05:22 AM syyl: https://youtu.be/jxWbz0Wf2rM
05:22 AM RyanS: now the Americans send it to China and they thread it on a Japanese made Swiss lathe
05:22 AM syyl: https://youtu.be/vAvfrrlMZg4
05:22 AM XXCoder: syyl: ohh yea saw it, amazing! very clear when plastic is almost impossible to cut that cleanlyt
05:22 AM miss0r: syyl: and when it comes to the 'have enough room', I'm also in a pinch here... I am effectively out of room.. At the moment I am resting my arms on a drawer system measuering 1100x1100x700, I just brought home... I need to figure out something :D
05:22 AM syyl: haha
05:22 AM syyl: :D
05:22 AM RyanS: and sell it on Aliexpress
05:22 AM syyl: i just moved a drawer cabinet out of my shop
05:22 AM syyl: to get a bit more room
05:23 AM miss0r: syyl: I need to start thinking about what I absoultly need in here and what I can do without. I only have 38m^2..
05:23 AM syyl: i am at
05:23 AM syyl: uhm
05:23 AM syyl: 25m^2
05:23 AM miss0r: Maho 500c takes up a good deal of that
05:24 AM miss0r: syyl: Damn. How do you even move around? :D
05:24 AM syyl: and i crammed the mill, a pantograph engraver, a shaper, surfacegrinder, lathe and a bit more in there..
05:24 AM miss0r: damn
05:24 AM miss0r: I wouldn't mind having a shaper in here
05:25 AM syyl: its only 200mm ram-stroke
05:25 AM miss0r: I still wouldn't mind :) Some things are just made alot easier with a shaper
05:26 AM miss0r: syyl: This is a photo of my shop: https://imgur.com/a/EeCcppX
05:26 AM syyl: ohwow
05:26 AM syyl: i would not mind the maho :D
05:26 AM miss0r: I gave away the x-carve last week. so I'm thinking the hole there needs to fit the new drawers
05:26 AM XXCoder: miss0r: honestly that is more room than space for my cnc router lol its in closet shelf being useless lol
05:27 AM syyl: http://gtwr.de/shop/pro_werkstatt_umbau_73.jpg
05:27 AM syyl: http://gtwr.de/shop/pro_werkstatt_umbau_77.jpg
05:27 AM miss0r: Alright, I can tell I need to stfu :]
05:27 AM syyl: i am always fighting space
05:27 AM miss0r: I hear'ya. But atleast you manage to keep it clean looking
05:28 AM RyanS: is that a BF45?
05:28 AM syyl: kinda
05:28 AM syyl: yes
05:28 AM miss0r: lol
05:28 AM rmu: how do they measure surface to 0.001µm or better
05:28 AM syyl: roughness?
05:28 AM syyl: or flatness
05:29 AM rmu: looks like a roughness measurement in the video
05:29 AM RyanS: send it to Switzerland
05:29 AM miss0r: I use a mansonry level.. preferably one with a bit of concrete still on one end
05:29 AM syyl: :D
05:29 AM miss0r: but only when it needs to be realy good
05:30 AM rmu: that is amazing. Ra <4nm
05:30 AM syyl: i think thats optical
05:30 AM rmu: thats 1/100 of the wavelength of blue light
05:30 AM miss0r: syyl: I envy your BF45... Its not always funny not to have a manual mill in here.
05:30 AM syyl: the simpler roughness gauges drag a diamond stylus over the part
05:30 AM syyl: like the infamous perthometer
05:30 AM rmu: yes that has to be contactless, else you would destroy the surface
05:31 AM syyl: just scratch it with the fingernail
05:31 AM syyl: "yeah, that feels like Ra0,01"
05:31 AM miss0r: :] hehe, with fingers like that, you could land a job anywhere
05:31 AM RyanS: is the masonry level where you paint it Prussian blue and rub it on the surface you're scraping in :-)
05:31 AM syyl: the bad touch?
05:31 AM syyl: *dadusch*
05:32 AM miss0r: RyanS: no, its much smarter than that. If you don't remove the concrete residue, it scrapes the part while you measure...
05:32 AM rmu: you surely have seen this https://www.youtube.com/watch?v=sFrVdoOhu1Q
05:32 AM RyanS: I have the BF30
05:32 AM syyl: thats close to lapping :D
05:32 AM syyl: yesss!
05:32 AM rmu: makes it sound easy
05:32 AM miss0r: rmu: Yeah!
05:32 AM syyl: mr. gelbart is very inspirational
05:32 AM miss0r: that is a beautiful lathe
05:32 AM syyl: i always love when he says
05:32 AM miss0r: I love it
05:32 AM syyl: "thats easy, got it from ebay, dirt cheap"
05:33 AM rmu: hehe
05:33 AM RyanS: don't think i'll ever cnc it
05:33 AM miss0r: I just love his accent
05:33 AM syyl: haha yes
05:33 AM rmu: somebody should force him to make more videos ;)
05:33 AM miss0r: send him one of those 'or else!' emails
05:34 AM miss0r: I want a lathe with granite bedways!
05:34 AM rmu: s/force/motivate/
05:35 AM miss0r: syyl: Do you make anything cool in that shop of yours? or is it just a very well build hobby shop?
05:36 AM syyl: its hobby and sidebuisness by now
05:36 AM syyl: www.gtwr.de
05:36 AM miss0r: Nice. Mine started out like that. Now I have quite my day job, and only work here/go to clients and repair/ajust their machines :]
05:37 AM RyanS: i've seen that video. 1 micron... is he bullshittg? can't even measure that with a micrometer
05:37 AM miss0r: hehehe. Steffan, I have seen your videos ;)
05:37 AM miss0r: You make some realy nice stuff
05:37 AM syyl: going part-time on the dayjob or leaving my dayjob completely is the long term goal
05:37 AM syyl: thanks
05:38 AM miss0r: Yeah, I can only urge you to do so. Its the best decision I ever made
05:38 AM syyl: but not with the current setup...a bit more room would be nice
05:38 AM syyl: to fit a larger surface grinder
05:38 AM miss0r: yeah. I bought a cute one from sweeden, actualy
05:38 AM miss0r: 400x200 work area
05:38 AM syyl: lot of things i want to do rely on a larger grinder
05:38 AM syyl: that would be a nice size
05:39 AM miss0r: Yeah, it has the size so that it JUST fits in here... well, I had to take off 30mm of the worktable legs, so the the grinder surface plate could move over the table a bit :D
05:39 AM syyl: :D
05:40 AM miss0r: I bought a Jacobsen SJ-16. But I never got it in here - thankfully
05:40 AM miss0r: IIRC it needed 3500mm of free space, to allot for the stroke
05:40 AM syyl: that would be perfect!
05:40 AM syyl: :D
05:40 AM rmu: I doN't know about situation in germany, but around here, it is nearly impossible to get some commercial metal working of any kind going in a residential area
05:40 AM syyl: i live in a mixed area
05:41 AM syyl: residential and commercial
05:41 AM miss0r: well, I ended up selling it for next to nothing to a machine dealer, that sent it to India for rebuilding
05:41 AM syyl: as long as I dont start to do heavy steel fabrication on sundays, its fine
05:41 AM syyl: or have a 40ton truck deliver stuff each day
05:41 AM miss0r: Now wheres the fun in that? :P
05:42 AM syyl: but fortunately i stick to small work
05:42 AM miss0r: What I would REALY love to make room for in here is a good bandsaw.
05:42 AM syyl: i kinda specialised on small parts
05:42 AM miss0r: The circular cold saw I have in here is having a hard time with the larger workpieces
05:42 AM miss0r: yeah
05:42 AM rmu: you would not get permits for a new place in austria, it would only be possible if some older permit is grandfathered in
05:43 AM XXCoder: rmu: new place? as in new building?
05:45 AM rmu: XXCoder: new building of old building that has different "widmung", don't know proper translation
05:46 AM rmu: so if you want to convert a warehouse into production and production involves metal stuff ("dangerous") and it is residential (or mixed, depends) zone, it would be a nogo
05:46 AM miss0r: I need to start taking stuff down from the wall, to fit this drawersystem in here... *sigh* wish me luck
05:50 AM miss0r: typical of me to mount stuff with waaay too long screws.
05:50 AM RyanS: the 'good old iron at bargain prices' doesn't exist in Australia and everything is expensive, industrial equipment wise
05:51 AM miss0r: Is it because the english didn't want you to have tools usable for escape till the late '80s ? :P
05:52 AM RyanS: probably
05:52 AM RyanS: I already blamed the British here
05:52 AM miss0r: :D
05:53 AM RyanS: all they gave us was the Irish... and rabbits
05:54 AM jthornton: morning
05:55 AM RyanS: but fortunately they gave us their BBC crime dramas
05:56 AM gloops: a lot of people around the world are missing british manufacturing
05:56 AM miss0r: damnit! The table I am standing at down, writing here; it also holds a small rolandDG desktopCNC, I need to raise it 22mm for the new drawers to fit ! >.<
05:57 AM gloops: those unassuming sturdy little things marked 'made in Britain'
05:57 AM gloops: made by the cheery british craftsman, last forever etc
05:57 AM RyanS: spoken like a true Brexiteer :P
05:58 AM miss0r: syyl: Didn't you use to have a cnc mill?
06:00 AM miss0r: lol @ RyanS
06:00 AM RyanS: back in the good old empire days when men wore top hats and shot foxes
06:01 AM RyanS: probably not at the same time
06:01 AM gloops: it wasnt that long ago
06:02 AM rmu: gloops: https://www.youtube.com/watch?v=cSKBQEEIjX8 ;-)
06:02 AM RyanS: I think Churchill wore one in the 20s
06:02 AM miss0r: I seriously use too many & too long screws !
06:04 AM rmu: hook from cars 2: "I remembered what they say about old British engines: it there ain't no oil under 'em, there ain't no oil in em."
06:05 AM gloops: rmu funny germany was quick to snap up our prestige marques
06:05 AM gloops: never saw the likes of a rolls royce come from europe
06:05 AM RyanS: didn't the British call hammers American screwdrivers
06:07 AM RyanS: the Germans are craftier though... hrrmm Volkswagen diesels
06:07 AM miss0r: Starting to move the drawer system into place now. Wish me luck. also, if you don't hear back from me within 30 minuts, send paramedics :P
06:08 AM gloops: im going to grind the crack out in this top slide
06:08 AM gloops: on closer inspection my hopes for a decent fix are pretty low, but nothing to lose by trying
06:09 AM gloops: no way of knowing what type of cast this is really, spark test wont tell much
06:10 AM gloops: probably any old scrap cast iron melted down, could be anything
06:11 AM RyanS: cast babbitt
06:11 AM RyanS: lol
06:16 AM miss0r: bleh. I'm in the situation, that I don't have anything other than a machinist level to line up these drawers with... That seems a bit over the top
06:16 AM miss0r: I seriously cannot find a regular level
06:18 AM RyanS: use your height gauge :-)
06:18 AM miss0r: lol
06:19 AM miss0r: Thats not an easy task with the raw concrete floor in here
06:19 AM rmu: miss0r: take a plumb line (?) and a square
06:19 AM miss0r: but ffs! If I could just find that level !
06:21 AM miss0r: This is driving me nuts... I own like 4 or 5!
06:27 AM asdfasd: just replaced 2.4.3 with 2.7.13 on very old machine, but now the keyboard jogging is a bit different, when hold shift key for fast jogging, few qick presses on arrows result randomly in one long move instead of few short, why is that?
06:28 AM jthornton: cpu overload
06:29 AM asdfasd: how to check and confirm if that is a CPU overload?
06:30 AM jthornton: cpu monitor from the menu
06:32 AM asdfasd: Im very sorry Im so clumsy with linux, where is that menu with cpu monitor?
06:34 AM jthornton: depends on which linux OS your using usually in a system menu
06:36 AM gloops: missor - follow the brickwork
06:37 AM miss0r: gloops: Then it is bound to be seriouslt off
06:37 AM asdfasd: found task manager which shows CPU load as digits only, but now the jogging works fine, so weird
06:37 AM gloops: you didnt build the garage miss0r?
06:38 AM miss0r: gloops: I only removed a few windows and changed out the roof
06:38 AM asdfasd: the CPU load is 40-50% with running linuxcnc on idle and 70% while jogging
06:38 AM miss0r: The walls are the original
06:40 AM gloops: well, bricks should be within a few mm
06:40 AM miss0r: these are not
06:43 AM asdfasd: when do fast jogging on 2 axes simultaneously the CPU load go to 89-90% is that too much?
06:43 AM miss0r: That sounds a bit high..
06:43 AM miss0r: Are you running it on a 386?
06:44 AM asdfasd: its very old pentium 4 2.2ghz single core
06:44 AM jthornton: what OS are you using?
06:45 AM asdfasd: the one that came with latest linuxcnc 2.7
06:45 AM asdfasd: not sure exactly what it is
06:45 AM gloops: hows the heatsink/fan working?
06:46 AM jthornton: asdfasd: that could well be your problem old hardware and latest OS, you would have been better to keep the old OS and just update LinuxCNC
06:46 AM gloops: im using an old optiplex 747, no problems
06:47 AM asdfasd: its all cold, the only hot is the GPU heatsing, but not too much, the normal temperature
06:48 AM asdfasd: jthornton: linuxcnc was too old and I had to go trhough few updates, also the hard drive begin to show errors, and I thought it would be easy to install a fresh one
06:49 AM gloops: wonder if it is finding graphics card, or using onboard one
06:49 AM jthornton: I have 3 machines running old hardware and using Ubuntu 10 and running the latest LinuxCNC
06:50 AM gloops: debian users will give prompt to lookup graphics card etc
06:50 AM asdfasd: that motherboard dont have onboard graphics
06:50 AM asdfasd: only AGP
06:52 AM asdfasd: I think today is working better, probably last night was overloaded by other running programs and just needed restart, will test it for a few days and then will see
06:52 AM gloops: well, thats my list of previous problems for those symptoms lol
06:55 AM asdfasd: I wouldnt update any soon but it seems the new PCB gcode with auto levelling doesnt work on the old linuxcnc
06:55 AM asdfasd: otherwise for everything else was working just perfect
06:56 AM jthornton: what error did you get with your G code?
06:57 AM asdfasd: there was a few, on P0 was showing out of range, and #5422 was showing non sense error message
06:58 AM asdfasd: had to edit the G code manually to make it compatible
07:00 AM gloops: right, slide is heating up, ive got 5 nickel rods to weld it only, smoke this cig and it gets welded
07:01 AM miss0r: gloops: You shouldn't smoke, its bad for you
07:01 AM * miss0r lights up a smoke
07:01 AM gloops: nothing else to do while im waiting
07:01 AM asdfasd: who is smoking - 1 cig time for rest, who is non smoking - continue working without a rest
07:02 AM gloops: yes thats a good reason to smoke asdfasd
07:02 AM miss0r: most of my mistakes are caught before they happen, because I stand back and have a cig
07:02 AM gloops: afk
07:03 AM asdfasd: lol
07:03 AM asdfasd: time to begin smoking
07:15 AM gonzo_: one place I worked at, the production team leads (middle age women) moaned about the engineers having longer tea breaks. As we tended to use them as meetings
07:15 AM gonzo_: but they would go in and smoke every hour
07:16 AM gonzo_: one day one of the wonem started having a rant, when an eng said that we were on a cig break. When she protested thatnon of us smoked, he pulled out some candy cigarettes and handed them around
07:19 AM asdfasd: Im self employed and my boss is also complaining about cigs....
07:29 AM jthornton: what the hell trying to install linuxcnc and I say Y to continue and the next line is Abort
07:29 AM gloops: well, apart from the general bitchiness of nickel rods, welded pretty well ..i think, now just to bring temp down without cracking it
07:31 AM gloops: i reckon the weld heat will be gone in 10 minutes, so after that ill take it down as a whole piece over another 10 minutes
07:31 AM gloops: in fact the weld heat will go quicker than that
08:02 AM gloops: hmm, not sure at what point welded casting is most likely to crack, it isnt stone cold yet but no sign of any cracking, might have got lucky
10:03 AM hazzy-dev: How is longer machine running time a plus? https://celos.dmgmori.com/en.html
10:09 AM jesseg: You can consume more candy cigs while waiting? :D
10:12 AM hazzy-dev: Or play more candy crush
10:12 AM jesseg: gonzo_, anyway that's a hilarious story about the cig break!
10:12 AM * hazzy-dev wonders if CELOS comes with games
10:50 AM unterhausen: did tom-itx ever get his kernel built?
10:50 AM unterhausen: might be doing that soon
11:06 AM devlap: hazzy-dev, less idle time, from faster machine operation and quicker setup times
11:06 AM devlap: Name of the production game is more work in less time.
11:08 AM devlap: higher utilization I guess is what they are highlighting.
11:37 AM hazzy-dev: devlap: That must be what they mean, but their choice of wording could be better :D
11:37 AM devlap: heh it is a bit of a freudian slip
11:42 AM fragalot: hi
11:42 AM hazzy-dev: unterhausen: I am building the kernel now, I am taking note off all the steps
11:42 AM hazzy-dev: hello fragalot
11:59 AM Loetmichel: *hihi* just repaired a "shitphone" for a co-worker... he managed to put it into the washing machine in the poket of his bathing robe after a bit of a hickup at the potty.... got everything de-oxidized but the chip for the touch... new display with touch digitizer was 69.90 eur... does anyone need a "brandnew" samsung AM-A310F display with non working touch chip? display has no cracks or pixel
11:59 AM Loetmichel: problems at all... ;)
12:01 PM Loetmichel: .... but MAAAN is that a workout to get the display seperated from the phones frame withour damaging either... took me nearly an hour of gently prying and heating with hot air.
12:05 PM hazzy-dev: my 4.16.8 RT kernel build notes for stretch, seems to be working ... : https://gist.github.com/KurtJacobson/9f8ae78dfcd7ba8576ae152018fcf123
12:13 PM enleth: Loetmichel: I've never had the chance to try it, but I'd be curious if this would work to unglue a smartphone screen: https://www.canford.co.uk/Images/ItemImages/large/55-123_01.jpg
12:13 PM enleth: that stuff is a bane of anything sticky
12:13 PM Loetmichel: enleth: probably
12:14 PM enleth: just make sure to get the actual Kontakt Chemie brand one, knockoffs are hit and miss
12:14 PM Loetmichel: but it would dilute a lot more than the glues you WANT to come off
12:14 PM Loetmichel: heat and prying is a lot more "precise" in what you want to come off and what you dont want to
12:15 PM Loetmichel: also its easier to rub/pull the residue off instead of smearing it all over the part with the solvent
12:15 PM enleth: as for prying, plastic wedges or spudgers are useful for "static" prying
12:15 PM enleth: just jam them in there and let the material's tension do the job, adjusting them from time to time
12:15 PM Loetmichel: i work occasionally with solvent 50 (what its called here)
12:16 PM Loetmichel: indeed thats how i did it
12:16 PM Loetmichel: also working my way around with two "pry tools" like you would on a car tyre with mounting irons
12:17 PM Loetmichel: i dont like the fact that the kontakt 50 tends to smear the glue all over the part because it dilutes it
12:17 PM enleth: I managed to unglue some pretty huge control panel faceplates with some spudgers and Label Off 50, mostly just by spraying more of it in there every so often and moving the spudgers when they got loose
12:17 PM Loetmichel: as long as you work with heat the glue stays put and can the pulled/rubbed off afterwards with ease
12:18 PM enleth: I found out that the diluted glue is easily cleaned off with more commonplace solvents that normally wouldn't affect it to begin with
12:18 PM enleth: so I don't consider it a huge issue
12:19 PM enleth: acetone or isopropyl, usually
12:19 PM enleth: they don't do shit by themselves, but do clean up the mess after Label Off is done with it
12:19 PM hazzy-dev: interesting, building LCNC seems to load up my PC much more than building this kernel, both run with -j4
12:20 PM rmu: hazzy-dev: linuxcnc contains some c++ parts, that may need way more memory to compile
12:21 PM hazzy-dev: ah, that makes sense
12:29 PM Tom_L: how do i purge unused items fro linux?
12:29 PM fragalot: Hello again.
12:29 PM Tom_L: got to the end of the build and ran out of space... dammit!
12:30 PM hazzy-dev: sudo apt-get autoremove ??
12:30 PM cradek: if it's debian, first try apt-get clean
12:31 PM cradek: yeah autoremove is worth a try too - that deletes things that were installed as dependencies but that are no longer needed
12:31 PM cradek: otherwise you'll have to figure out what packages you want to remove, which can be tricky
12:32 PM Tom_L: i'll just find a larger ssd and start again
12:32 PM Tom_L: i was afraid this one might be too small
12:33 PM Tom_L: neither one of those did much if anything
12:34 PM cradek: :-/
12:34 PM gloops: welding of lathe slide casting appears successful
12:34 PM hazzy-dev: Tom_L: How big is your SSD? I have only 32GB here, and lots of files etc ...
12:36 PM Tom_L: 32
12:36 PM Tom_L: so if you're gonna build it you may need something bigger
12:37 PM Tom_L: i think i'll run it on a faster machine this time too
12:43 PM hazzy-dev: Its been cranking away here for about an hour, I hope it has enough room to finish
12:43 PM Tom_L: mine got to the last step :)
12:48 PM Tom_L: does it require having preempt installed before building the kernel?
12:54 PM Tom_L: hazzy-dev did you add all those extra packages?
12:56 PM hazzy-dev: Yes, I did apt-get install build-essential bin86 libqt4-dev libncurses5-dev pkg-config bison flex libssl-dev libelf-dev
12:56 PM Tom_L: ok
12:56 PM Tom_L: i was gonna post the script if you still want it
12:57 PM Tom_L: pretty sure it's ok now but haven't run it all the way thru
12:58 PM hazzy-dev: It would be great if you could post it, I would like to compare with what I have
12:58 PM hazzy-dev: https://gist.github.com/KurtJacobson/9f8ae78dfcd7ba8576ae152018fcf123
12:59 PM hazzy-dev: ^ What I did
12:59 PM Tom_L: i added apt-get bc
12:59 PM Tom_L: i put the extra ones we added at the bottom for now
12:59 PM Tom_L: http://paste.debian.net/1026605/
01:00 PM hazzy-dev: did you get an error without bc?
01:00 PM Tom_L: yes
01:00 PM hazzy-dev: hmm
01:00 PM Tom_L: unless one of the other packages takes care of it. i installed it first
01:01 PM Tom_L: well 4th
01:01 PM Tom_L: of the extra packages
01:01 PM Tom_L: installing stretch right now
01:01 PM hazzy-dev: Ah, I already have it installed, another pakage must depend on it
01:02 PM Tom_L: i started with a fresh install
01:02 PM Tom_L: so the script should work that way
01:02 PM hazzy-dev: good to test the script on a clean install
01:03 PM Tom_L: are you root or sudo?
01:03 PM hazzy-dev: sudo
01:03 PM hazzy-dev: do you think there any reason not to have all the apt-get installs on the same line at the top of the script?
01:03 PM Tom_L: do i need a version of preempt installed before running this?
01:04 PM pcw_home: no
01:04 PM hazzy-dev: I don't think it should matter what kernel you build it on
01:05 PM pcw_home: in fact it may build slightly faster on a stock kernel
01:06 PM pcw_home: (a stock non-rt kernel)
01:06 PM pcw_home: which are tuned for throughput not latency
01:09 PM Tom_L: running
01:10 PM Tom_L: 500g this time.. better not run outta space
01:13 PM Tom_L: building packages
01:22 PM asdfasd: Im I doing something wrong or MAX_LINEAR_VELOCITY in DISPLAY override MAX_VELOCITY in AXIS instead of opposite?
01:25 PM asdfasd: ops, my fault, nevermind
01:26 PM gloops: np
01:27 PM hazzy-dev: Tom_L: Still building here
01:28 PM Tom_L: yeah same here
01:28 PM Tom_L: but i was late to the party
01:29 PM Tom_L: i should swap out that MB for the new gigabyte that's sitting in the closet
01:30 PM hazzy-dev: CPU load just went way down, may be getting close now
01:30 PM Tom_L: where do i see that?
01:30 PM hazzy-dev: applications > system > task manager
01:31 PM hazzy-dev: What MB are you running now?
01:31 PM hazzy-dev: DONE!!!!
01:31 PM hazzy-dev: now to install
01:31 PM Tom_L: i'm compiling on a gigabyte right now but the target is a j1900
01:34 PM hazzy-dev: I have a bunch of machines running stretch, how do I install the kernel on the other machines, just copy the build dir over and sudo make install?
01:37 PM hazzy-dev: Running sudo make install
01:39 PM hazzy-dev: Going down to boot the new kernel!
01:39 PM Tom_L: what did you change in the xconfig?
01:39 PM Tom_L: just those 3 things?
01:39 PM hazzy-dev: yes, but they were already set correctly
01:40 PM Tom_L: 2 of 3 were on mine
01:42 PM hazzy-dev: kurt@T510:~$ uname -a
01:42 PM hazzy-dev: Linux T510 4.16.8-rt3 #1 SMP PREEMPT RT Fri May 25 12:17:04 EDT 2018 x86_64 GNU/Linux
01:42 PM hazzy-dev: Hurray!
01:43 PM Tom_L: done
01:44 PM Tom_L: how do i install it now?
01:44 PM hazzy-dev: That was fast
01:44 PM hazzy-dev: sudo make install
01:44 PM Tom_L: i thought that was in the script
01:44 PM hazzy-dev: should be
01:44 PM Tom_L: but uname reports 4.9.88 still
01:45 PM hazzy-dev: Did you reboot?
01:45 PM Tom_L: oh
01:45 PM hazzy-dev: :)
01:45 PM Tom_L: i thought you never rebooted linux :)
01:45 PM Tom_L: yup, 4.16.8
01:46 PM hazzy-dev: Almost true, except then you change linuxes :D
01:47 PM hazzy-dev: knowing linux nerds, there probably is some way to load a new kernel without rebooting,
01:48 PM Rab: There is. Or was, some years ago. Highly experimental though.
01:48 PM Tom_L: so i should build on that pc
01:48 PM Rab: hazzy-dev, you also have to make your bootloader point to the new kernel.
01:49 PM Rab: Wait, maybe I'm missing something.
01:49 PM Tom_itx: Linux Stretch 4.16.8-rt3 #1 SMP PREEMPT RT Fri May 25 12:37:54 CDT 2018 x86_64 GNU/Linux
01:49 PM hazzy-dev: I think stretch automaticaly loads the newest kernel,
01:51 PM Tom_itx is now known as Guest1963
01:51 PM hazzy-dev: With wheesy I had to always select the RT kernel (or edit the grub config)
01:51 PM Tom_L: huh
01:51 PM Tom_L: freenode doesn't like me
01:51 PM pcw_mesa: Yeah I think that's normally automatic (either because its that latest or something make install does)
01:51 PM Tom_L: so the script is verified.
01:52 PM pcw_mesa: it should also work on things like mint or ubuntu
01:54 PM hazzy-dev: Latency seems about the same as before, 48000 ns
01:55 PM pcw_mesa: the main improvement I've seen with 4.16 is that it does not have the horrible latency that 4.4 through 4.14 have on some older hardware
01:56 PM pcw_mesa: so for a LinuxCNC distribution for example it means you dont need multiple kernels to support a wide range of hardware
01:58 PM hazzy-dev: Which is great! Hopefully this will be good enough on most hardware to drop wheezy and RTAI
01:58 PM Tom_L: so can you copy that install directory and install to several pcs?
01:58 PM hazzy-dev: Please say yes
01:59 PM Tom_L: i can pull the other hdd and install it but i didn't wanna mess it up on the first round
01:59 PM Tom_L: probably just as quick to do that
02:00 PM hazzy-dev: Tom_L: Your make went really fast, I think it took at most a quarter the time it did here
02:01 PM Tom_L: servo thread jitter: 17223
02:02 PM Tom_L: 23k with 4 yt goin
02:03 PM pcw_mesa: I think the meltdown/spectre stuff is enabled by default but you might check
02:03 PM Tom_L: what's that?
02:03 PM pcw_mesa: relatively new security vulnerability in Intel hardware
02:04 PM Tom_L: oh, bios setting..
02:05 PM pcw_mesa: dmesg | grep iso
02:05 PM hazzy-dev: Yep, enabled
02:06 PM Tom_L: same on this pc but it's not staying there
02:06 PM hazzy-dev: Seems this machine is more snappy overall with the new kernel
02:08 PM hazzy-dev: Tom_L: How do you disable it?
02:08 PM Tom_L: i ask pcw
02:08 PM Tom_L: then he tells me to go into the bios..
02:09 PM hazzy-dev: ah, thanks
02:11 PM Tom_L: ok, i'll fix the other ssd this evening.
02:11 PM Tom_L: run latency before and after
02:16 PM fragalot_: pcw_mesa: not only intel - many ARM chips are hit with that as well
02:16 PM pcw_mesa: Really?, didn't know that
02:17 PM fragalot_: the STM32F7 series we use at work has the same problems
02:17 PM pcw_mesa: theres supposed to be a performance hit by enabling the patch, but I have not noticed any big change
02:17 PM fragalot_: it depends on what you do
02:17 PM fragalot_: if you're not powering through mainframe server loads of data, you're unlikely to notice
02:18 PM Tom_L: 4 glxgears & yt servo thread: 54860
02:18 PM Tom_L: before the kernel change
02:19 PM pcw_mesa: what CPU?
02:19 PM Tom_L: j1900
02:20 PM Tom_L: just put that there so i can check the log tonight
02:20 PM pcw_mesa: It will probably get higher eventually... I think I get somewhere around 30000 on my old Core Duo
02:22 PM fragalot_: pcw_mesa: so when are you releasing an FPGA based mesa master card that processes the gcode remotely to do away with jitter all together?
02:23 PM pcw_mesa: Well the DPLL gets jitter down to ~ 50-100 ns so I think that's probably good enough :-)
02:23 PM fragalot_: :p
02:25 PM pcw_mesa: still only on reads so there's still write jitter but that's a lot less important
02:28 PM pcw_mesa: (for velocity control loops, write jitter only causes second order errors during acceleration)
02:28 PM sync: fragalot_: is there an actual POC for it on F/H7 or F4?
02:29 PM fragalot_: sync: I don't see why the "standard" ARM variants wouldn't work
02:29 PM fragalot_: the F7's certainly have the same pipelining architecture that makes it vulnerable
02:30 PM fragalot_: as well as caching
02:31 PM fragalot_: which makes it a very fun platform to do high-speed realtime applications on :-)
02:31 PM rmu: fragalot_: cortex M7 usually has no memory protection, so who cares
02:32 PM sync: you can turn off caching tho
02:32 PM rmu: you don't execute untrusted code on those arm µCs in contrast to PCs (javascript in browsers can exploit spectre/meltdown&co)
02:32 PM fragalot_: sync: sure, but it's nice to have for the non-realtime stuff
02:33 PM fragalot_: rmu: of course, but that doesn't make it immune
02:33 PM rmu: fragalot_: in a sense the cortex Ms are immune because there is no threat
02:33 PM fragalot_: and there are memory protected regions.
02:33 PM sync: you can use the MPU to protect memory regions
02:33 PM sync: but tbh there is no risk
02:34 PM fragalot_: I never claimed there was a significant risk
02:34 PM fragalot_: I just said they /ARE/ vulnerable.
02:34 PM rmu: problematic is stuff like raspberry pi
02:34 PM sync: I mean, so is any cpu that has a pipeline more or less
02:34 PM rmu: cortex A
02:34 PM sync: but this was known since the early 90s
02:36 PM rmu: hmm. exploiting a pipeline to read priviledged memory locations sounds tricky
02:37 PM fragalot_: it is tricky
02:37 PM fragalot_: but possible.
02:38 PM rmu: doesn't spectre and meltdown rely on speculative execution of some sort and examining "leaks" of those non-executed speculations
02:38 PM fragalot_: yes
02:38 PM fragalot_: it's a slow attack
02:38 PM rmu: but pipeline != speculative execution
02:39 PM fragalot_: pipelining opens up the door because it could pre-loads data you may not have normally had access to.
02:42 PM rmu: if your processor is not superscalar i expect the memory access error to raise an exception asap
02:42 PM rmu: nevermind
02:42 PM rmu: off topic
02:43 PM rmu: hennesy patterson ;)
02:44 PM fragalot_: :-)
02:50 PM Tom_L: pcw_home, abou 2/3 the way down.. would that work to make a deb for this kernel? https://debian-handbook.info/browse/stable/sect.kernel-compilation.html
02:50 PM Tom_L: $ make deb-pkg LOCALVERSION.....
02:59 PM fragalot_: CaptHindsight: seems uber's car DID see that cyclist but disabled the emergency stop functionality.. as well as the "alert driver" functionality... >.< what is the point in detecting it then!
02:59 PM Tom_L: 2nd ssd updated
03:04 PM Tom_L: ok, on the J1900 it's worse. 4 glxgears, yt servo thread: 185314
03:10 PM asdfasd: recently did upgrade, with old linux when visit local network shared folder it get mounted outomatically on .gvfs , after the upgrade it doesnt
03:10 PM asdfasd: any idea how to turn it on?
03:13 PM hazzy-dev: Tom_L: That is almost 4x the latency you got with the old kernel? Yikes!
03:18 PM Tom_L: yep, may not work as good on some machines
03:19 PM Tom_L: is there an easy way to remove it and revert to the old one?
03:22 PM JT-Shop: Tom_L: boot to another kernel and use the synaptic package manager to delete it
03:22 PM Tom_L: this one isn't in the package manager
03:23 PM JT-Shop: oh well
03:28 PM hazzy-dev: Tom_L: In GRUB go to advanced options (or something like that) and choose the old kernel
03:29 PM hazzy-dev: You can set the default kernel in grub.confg, I can't remember where that file is, but its easy to find
03:29 PM miss0r: fragalot_: You around?
03:30 PM fragalot_: miss0r: yes
03:30 PM miss0r: I just got my new drawers into the shop today
03:31 PM fragalot_: any good?
03:31 PM hazzy-dev: You you may be able to say sudo make uninstall to remove it
03:31 PM miss0r: uploading a photo now, it is realy good
03:31 PM miss0r: fragalot_: https://imgur.com/a/tgm6Jac
03:32 PM miss0r: Still a bit of cleaning up in the surroundings, as it made a bit of a mess :]
03:32 PM fragalot_: :D
03:32 PM fragalot_: That vise does not look right on that little mill :P
03:33 PM miss0r: well, it came with the mill. So I just keep on using it on there ;)
03:33 PM miss0r: when I only need to clamp small things
03:33 PM fragalot_: but yeah - those cabinets ROCK.
03:34 PM miss0r: slowly starting to sort the bolt collection: https://imgur.com/a/Dfz8rdN
03:34 PM miss0r: This is waaay better use of my space, than that x-carve that was there before :]
03:35 PM fragalot_: i've been thinking of replacing my wall of DIY wooden ones with a metal cabinet
03:35 PM fragalot_: gives me more drawers than i've got now with less dead space
03:35 PM miss0r: I hear'ya.. the problem is; they are expensive :)
03:35 PM fragalot_: indeed
03:35 PM fragalot_: which is why I made wooden ones xD
03:36 PM miss0r: yeah, I got this cheap; I only payed ~750eur for it
03:36 PM miss0r: well, its still alot of money, but that is roughly 1/3 of the price for a new one this size
03:37 PM fragalot_: about the same as a china one
03:37 PM fragalot_: (with a lot less drawers :P)
03:38 PM miss0r: yeah... When putting this much load on the drawers, I wouldn't trust chinesium. Especially with all the bolts that would be one big mismash should it drop to the floor
03:38 PM fragalot_: yup
03:40 PM miss0r: fragalot_: Are you moving forward with your projects?
03:40 PM fragalot_: got a date tomorrow with a machinist
03:41 PM fragalot_: hopefully get the rf45 milled back to square
03:42 PM miss0r: Sounds nice. Be sure to ask him if it is okay to take alot of pictures of the process
03:42 PM miss0r: And he has all the needed cutters for the job?
03:43 PM fragalot_: he should do
03:43 PM fragalot_: if not, we can grind one up
03:44 PM miss0r: if he is the right calibre. I hope you don't go in vain.. not realy what that project of yours need ;)
03:44 PM fragalot_: I trust him :-)
03:44 PM miss0r: It will be fun to read about, nevertheless, but still ;)
03:44 PM fragalot_: sad thing is that he's 67 so i'm not sure if he's going to still be doing this in 10 years
03:44 PM miss0r: yeah.. all the good machinists are getting old it seems
03:46 PM fragalot_: especially knowledgable & versatile ones
03:46 PM miss0r: yeah. Perhaps people like that only reach that state for the last 10 years of their working life
03:47 PM miss0r: which is what makes it seem like all the good ones are on their way out one way or the other
03:47 PM fragalot_: it's a bit of a tricky trade to get started in as a youngling
03:48 PM fragalot_: the tooling is insanely expensive, materials are expensive, and it's so easy to get bamboozled by a malicious sweet-talking purchasing department of a larger business that needs parts/service
03:49 PM miss0r: Sure is
03:49 PM asdfasd: how to easily acces network folder on linuxcnc?
03:49 PM miss0r: from linuxcnc?
03:49 PM miss0r: or a folder ON linuxCNC?
03:50 PM asdfasd: from linuxcnc before I as able to open .gvfs
03:50 PM asdfasd: now it is empty
03:50 PM miss0r: is it a standard windows network folder?
03:50 PM asdfasd: yes
03:51 PM miss0r: what distribution are you running?
03:51 PM asdfasd: before the upgrade after visiting network folder it was mounted automatically on .gvfs
03:51 PM asdfasd: after the upgrade now it doesnt mount automatically
03:51 PM asdfasd: just installed the latest linuxcnc 2.7.13
03:51 PM miss0r: can you mount it manually ?
03:51 PM miss0r: What output does this give: cat /etc/issue
03:52 PM asdfasd: probably yes, but wanted some quick access as before
03:52 PM miss0r: I can help you set that up in a hurrt. What does 'cat /etc/issue' output?
03:52 PM asdfasd: so I can open G code from local network
03:52 PM asdfasd: let me check
03:53 PM asdfasd: debian 7
03:53 PM miss0r: Alright
03:53 PM asdfasd: on the old linux I had Nautilus file browser
03:54 PM asdfasd: which mount automatically any visited network folder to .gvfs
03:54 PM miss0r: Just to make sure; make sure you have root or sudo, and run 'apt-get install cifs-utils'
03:54 PM miss0r: I like to mount anything to /mnt/[share name]
03:54 PM miss0r: But we can mount it to whatever you like, realy
03:55 PM asdfasd: .gvfs is easy to access from linuxcnc
03:56 PM miss0r: Alright. Where is this .gvfs directory located?
03:56 PM asdfasd: home/user
03:56 PM JT-Shop: I like to sshf into other computers so I can just use the file manager to do stuff
03:57 PM miss0r: Alright. Did you run the last command I posted?
03:57 PM asdfasd: yes, installed
03:57 PM miss0r: JT-Shop: yeah
03:57 PM miss0r: asdfasd: Alright, as root/sudo open /etc/fstab in your favorite editor
03:58 PM miss0r: Is the share you are going to access protected with a username/pass?
03:59 PM asdfasd: no username and pass, just different local shares free for everyone
03:59 PM asdfasd: whant to access them easy
03:59 PM miss0r: Are we talking multible different shares?
04:00 PM asdfasd: yes
04:00 PM miss0r: gah.... How did you go about this before?
04:00 PM asdfasd: as I did mention before - one visit to any local share was automatically mounted to .gvfs
04:00 PM * JT-Shop has proved he can cut off the 1 1/2 PVC pipe in that damn tight spot... now to cut it straight
04:00 PM asdfasd: the file browser used before was old version of Nautilus
04:01 PM asdfasd: now just installed a new version, which doesnt do the same in .gvfs
04:02 PM asdfasd: the browser is showing as mounted but .gvfs remain empty
04:02 PM miss0r: Well... I don't know about that, sorry. I can teach you to have specific shares mounted on bootup/manually mount shares via commandline.
04:02 PM miss0r: I cannot help you with nautilus
04:03 PM miss0r: why all the different shares, if you don't mind me asking?
04:04 PM miss0r: fragalot_: My brother inlaw, which I gifted the x-carve to, already started making money with it :D
04:05 PM asdfasd: because different types of G code are located in different places, it will be easy to access all of them instead of keep copy each one in 1 folder
04:05 PM fragalot_: miss0r: o.O
04:06 PM miss0r: fragalot_: yeah, apparently he made a risk(the game, do you know it?) board, modeled after Denmark, and posted a picture on instagram(friggin hipster). Within 2 hours he had 6 orders
04:07 PM fragalot_: I know that game very well
04:07 PM fragalot_: never managed to win though
04:08 PM fragalot_: lol nice
04:09 PM miss0r: Me neither(the winning part)... That a-hole always win
04:23 PM miss0r: I think it is safe to say, that I will get no more work done tonight
04:23 PM fragalot_: hah
04:24 PM fragalot_: do you ever when you're on here?
04:24 PM miss0r: not _while_ I do the writing, no. But sure
04:24 PM miss0r: more often than not anyway
04:25 PM miss0r: Bleh... I spend ~100eur on a holder for the new tork paper rolls...
04:25 PM miss0r: Apparently it also works for the wider models - so I cannot fit it anywhere
04:25 PM miss0r: *sigh*
04:25 PM fragalot_: yea.. tork is not cheap
04:25 PM miss0r: I got a pretty good deal on the paper, actualy
04:26 PM miss0r: I got two fiber paper rolls(dual layers ect) for 50eur.
04:26 PM miss0r: Both hold 250 meters...
04:26 PM miss0r: That should last me a while. But I am somewhat pissed about the wallmount paper roll holder
04:26 PM fragalot_: cut it in half :P
04:27 PM miss0r: hehe, They did what they could to make that hard on me
04:27 PM fragalot_: :-)
04:27 PM fragalot_: screw a bucket to the wall, put paper roll in bucket, stick through hole in lid
04:27 PM fragalot_: job done
04:27 PM miss0r: I would have been much happier with those old 'wire frame' ones...
04:28 PM miss0r: Hehe. This is the kind that needs to be rolled off the outside
04:28 PM miss0r: You can see it on the photo I posed of the drawers, I think
04:28 PM fragalot_: still works :P
04:29 PM miss0r: I will not listen to you! :] I shall make room for this holder. It was so damn expensive, and I cannot return it now
04:31 PM * fragalot_ has a wooden dowel for his rolls
04:31 PM miss0r: which would be plenty fine :]
04:31 PM fragalot_: and a *HUGE* bag of those oil spill mats
04:31 PM miss0r: Yeah.. How much did you pay for those?
04:31 PM fragalot_: lemme check
04:32 PM fragalot_: €47 for 200
04:32 PM Deejay: gn8
04:32 PM miss0r: Thats now bad
04:32 PM miss0r: nite nite Deejay
04:32 PM fragalot_: SPC200-3-E
04:33 PM miss0r: fragalot_: That roughly buys you half a rag mount, you cannot fit
04:33 PM fragalot_: :P
04:34 PM fragalot_: at the rate i'm using these at though,...
04:34 PM fragalot_: I think i'll be alright for another few years xD
04:34 PM miss0r: yeah hehe
04:34 PM miss0r: Well, you don't realy have the room to make a mess of at the moment. You have already managed that
04:35 PM fragalot_: :-)
04:36 PM miss0r: It pisses me off with this rag mount! I mean, it is just so unnecessarily big!
04:36 PM fragalot_: does it fit 2 rolls?
04:36 PM miss0r: "We need plenty of room for our logo"...
04:37 PM miss0r: no... its 20mm too short :O lol
04:37 PM miss0r: but damn close...
04:37 PM fragalot_: put the second roll on the bandsaw
04:37 PM fragalot_: or mount it in the lathe & part off 20mm
04:37 PM fragalot_: :P
04:38 PM fragalot_: i've never seen that style of mount before though
04:38 PM miss0r: sure you have... it just doesn't make sense, what you see on the picture
04:39 PM fragalot_: enlighten me
04:40 PM miss0r: https://imgur.com/a/HaK9Uib
04:40 PM miss0r: (upside down, if in doubt)
04:41 PM fragalot_: the wire frame ones are the same size aren't they?
04:41 PM miss0r: I must have picked the wrong model, this is just awfull
04:41 PM miss0r: I seem to recall being able to get them in a version that fits these rolls
04:42 PM miss0r: The only place I realy have the room to fit this holder is on the inside of the door.. and theres a 10/10 chance of that pissing me off on a daily basis
04:42 PM fragalot_: xD
04:42 PM fragalot_: ceiling mount
04:42 PM fragalot_: OR... make a mobile cart
04:42 PM miss0r: and a spring retainer on the cutoff
04:43 PM fragalot_: we've got one at work, it's great
04:43 PM * miss0r slaps fragalot_
04:43 PM fragalot_: every time you pull off some paper, assuming it's there, it falls over
04:43 PM fragalot_: and you walk into it when you don't need it
04:43 PM miss0r: Theres no real use of making it mobile, as theres realy only room to fit one cart in here, and no room for it to move around
04:43 PM miss0r: lol
04:43 PM miss0r: Yeah, sounds like my experience with carts as well
04:44 PM fragalot_: :P
04:44 PM miss0r: Permanently mount it on the lathe... 12 speed paper dispencer !
04:45 PM fragalot_: mount an exacto knife in one of the tool holders
04:45 PM miss0r: ... not enough, I realy need to get around to installing that VFD
04:45 PM miss0r: lol
04:45 PM miss0r: mad the holder only been smaller, I had the perfect location for it
04:45 PM miss0r: BUT IT IS NOT, BY GOD IT IS NOT!
04:46 PM miss0r: alright.. no more coffee for me
04:46 PM miss0r: I'll make one myself
04:48 PM fragalot_: that's the spirit
04:48 PM * fragalot_ hands miss0r a dowel
04:49 PM asdfasd: Im not sure how, but now it works, I think gvfs-fuse wasnt installed
04:49 PM miss0r: Making it realy simple: https://imgur.com/a/eGdSiWT
04:50 PM miss0r: the 'spring release' is just the acurately calculated flex in the flatbar stock bracket ;)
04:50 PM asdfasd: and also doesnt work without restart
04:50 PM fragalot_: :P
04:51 PM fragalot_: miss0r: before my holder was a piece of string on 2 hooks :P
04:51 PM miss0r: :D I see you are moving your way up the ladder of evolution
04:51 PM fragalot_: indeed
04:51 PM fragalot_: I see no reason to upgrade further :-)
04:51 PM miss0r: I used to do something like that for wire drums, but it drove me bat shit crazy
04:52 PM fragalot_: nah those go on a shaft that's got a garden hose shoved over it to make it a bit grippy
04:52 PM miss0r: :D
04:52 PM fragalot_: because nothing sucks more than an entire 1000m drum unspooling itself
04:53 PM miss0r: You mean 100m, surely?
04:53 PM fragalot_: yes
04:53 PM miss0r: but sure.. a 1000m one unspooling itself is roughly 10x as annoying
04:54 PM fragalot_: I should do the same for my emery paper, actually
04:54 PM fragalot_: the 40 grit keeps unspooling itself if I look at it funny
04:54 PM miss0r: Stop looking at it funny then. Theres nothing funny about 40 grit
04:54 PM CaptHindsight: is that a pizza dough spreaderouter?
04:55 PM fragalot_: :D
04:55 PM miss0r: CaptHindsight: You, sir, have a very keen eye
04:56 PM miss0r: I seem to recall having a round steel table leg, with a nice flange at the end laying around somewhere. That would make a nice dowel actualy
04:56 PM fragalot_: bet you it's nearly the right diameter too
04:56 PM miss0r: IIRC it is damn close
04:57 PM miss0r: but chances are I threw it out a while back...
04:57 PM CaptHindsight: someone asked me about having LCNC control a robot that can recover from having it's arms deliberately interfered with, like the robot dogs
04:57 PM CaptHindsight: it's/its
04:58 PM CaptHindsight: it would need redundant sensors to check if the arm or joint is broken vs say shoved by an external force
04:59 PM miss0r: Sounds like a fun project
04:59 PM gloops: good job they dont have speed bumps in china https://media.mnn.com/assets/images/2017/11/man_beijing_bike_recyclable_materials.jpg.653x0_q80_crop-smart.jpg
04:59 PM miss0r: fragalot_: The local low price builders mart: https://www.jemogfix.dk/bordben-oe-30-mm-x-50-cm-krom/1106/9031840/
05:00 PM fragalot_: I have no ideqa what that is in real money
05:00 PM fragalot_: THAT DAMN Q
05:00 PM JT-Shop: yea my chicken coop temperature graph is finally working as planned
05:00 PM miss0r: What, you never played monopoly?
05:00 PM CaptHindsight: but for their application it would be like having a mill be able to recover from a tree falling on it while cutting
05:00 PM miss0r: fragalot_: about 8 eur or so
05:01 PM fragalot_: lol costs more to look it up
05:01 PM miss0r: :]
05:02 PM gloops: get one of those extending wardrobe poles - no need to cut it to size then
05:02 PM miss0r: gloops: This seems like a cheaper solution
05:02 PM gloops: well i didnt read what it was for tbh lol
05:05 PM CaptHindsight: looks like a very uncomfortable bar stool
05:06 PM CaptHindsight: oh it's a table leg
05:06 PM JT-Shop: silly SVG coordinate system the Y axis 0 is at the top
05:06 PM CaptHindsight: make more sense
05:06 PM miss0r: Its s stripper pole for midgets
05:07 PM miss0r: well.. that is what I am going to use it for, anyway
05:07 PM fragalot_: I'm off -- ttyl :-)
05:07 PM miss0r: cya
05:07 PM CaptHindsight: the PC term is little people
05:08 PM gloops: i doubt little is still a legal word
05:08 PM gloops: unless aimed at hands
05:08 PM miss0r: If we are getting technical about it, I am talking about Pygmy
05:08 PM gloops: pygmies are extinct

05:12 PM * JT-Shop straps on a pistol to go fetch the paper
05:13 PM CaptHindsight: JT-Shop: rough neighborhood?
05:18 PM * JT-Shop lives out in the woods with wild animals
05:19 PM CaptHindsight: we had deer blocking traffic earlier
05:20 PM gloops: ive got an order for 30 mdf swords
05:20 PM XXCoder: fancy
05:21 PM gloops: props
05:21 PM XXCoder: I know. lol
05:21 PM XXCoder: its always prop or decoactive if its mdf
05:21 PM XXCoder: or maybe cast postive
05:22 PM gloops: it is useful stuff really
05:23 PM gloops: it really ought to me made from recycled wood, i dont like the idea of forests being cut down to make pointless throwaway stuff
05:24 PM SpeedEvil: MDF is often largely recycled isn't it?
05:24 PM JT-Shop: XXCoder: I had to reach in a small hole and cut off the 1 1/2" PVC P trap... got it crooked and had to cut it again
05:24 PM JT-Shop: that really sucked but it's done
05:24 PM gloops: i dont know, i sort of assumed it was, but no idea really, i bet it isnt
05:24 PM XXCoder: jt aw. so it wasnt accessable otherwise?
05:25 PM XXCoder: mdf is made from sawdust if I recall right but maybe not
05:25 PM JT-Shop: no, room below fully finished off so it was a tough one
05:26 PM JT-Shop: I did spend an hour or more seeing if there was another way
05:26 PM gloops: yes, seems it is mainly recycled mill waste
05:42 PM flyback is now known as phlyback
05:46 PM asdfasd: made nautilus default file manager, but when I open folder from desktop still is opening the old file manager, how ti fix it?
05:48 PM XXCoder: asdfasd: some is just hardcoded but there may be desktop manager specific setting?
05:50 PM asdfasd: cant find it
05:51 PM JT-Shop: right click on the file...
05:52 PM JT-Shop-2: sorry wrong tab
06:05 PM Tom_L: what's an easy way to write over the boot sector in linux?
06:05 PM Tom_L: i did it once and now i forgot how i did it
06:05 PM phipli: use dd?
06:05 PM Tom_L: i need to make sure grub is erased
06:05 PM JT-Shop-2: format c
06:05 PM Tom_L: no that doesn't do it
06:06 PM JT-Shop-2: phipli: got my temperature chart working
06:06 PM Tom_L: i think i wrote 0xFF or something over it for a while then ctrl-c'd out
06:06 PM phipli: can't you just delete it in gparted?
06:06 PM phipli: JT-Shop-2, awesome!
06:06 PM phipli: JT-Shop-2, got a picture of it?
06:06 PM phipli: what way did you do it in the end? SVG or something fancy?
06:08 PM JT-Shop-2: SVG
06:10 PM phipli: excellent
06:11 PM JT-Shop-2: damn imagebin want a donation to post an image
06:11 PM phipli: :)
06:12 PM Tom_L: which one?
06:12 PM JT-Shop-2: imagebin.ca
06:12 PM Tom_L: .com .ca
06:12 PM JT-Shop-2: https://ibb.co/iMZAMT
06:13 PM JT-Shop-2: phipli: trick was to subtract the 0 location from the Y axis to get it to be the right way around silly SVG Y0 is top of the viewport
06:13 PM phipli: did you manage to use anything from my code? (I admit it was messy :) )
06:13 PM phipli: yeah, I'm kind of used to top left for graphics
06:14 PM JT-Shop-2: I did look it over a lot but first I had to learn SVG so I ended up just rolling my own
06:14 PM phipli: Tom_L, for reference : http://elephantandchicken.co.uk/temperature/
06:14 PM phipli: all about the svg temperature plots
06:14 PM JT-Shop-2: the graph is a 24 hour graph with readings each 1/2 hour
06:15 PM JT-Shop-2: going to add humidity and pressure next
06:15 PM phipli: mine is 24 hours at 15 minutes atm
06:15 PM phipli: because it made an image at about the right size at 4px per reading
06:16 PM phipli: your temp is very stable
06:16 PM phipli: mine is weird today because it has been raining and overcast
06:16 PM JT-Shop-2: it's only a few hours old, I just fixed the offset
06:16 PM JT-Shop-2: from 0
06:17 PM JT-Shop-2: be interesting to see the humidity/pressure history
06:17 PM phipli: I have some humidity sensors in a bag upstairs
06:18 PM phipli: should probably attach one to the mcu
06:18 PM phipli: dht-22s or something
06:18 PM Tom_L: so how would dd do it?
06:18 PM JT-Shop-2: well this is day 8 of the bathroom remodel and still no shower pan in place
06:19 PM JT-Shop-2: I'm getting close to setting it :)
06:19 PM JT-Shop-2: once that is done it's all downhill from there
06:19 PM phipli: near enough - got some of these (as well as other things, including the same as yours) https://www.banggood.com/AM2320-DC-3_1-5_5V-Digital-Temperature-And-Humidity-Sensor-Single-Bus-I2C-Signal-Output-p-1174728.html?rmmds=search&cur_warehouse=CN
06:20 PM phipli: Tom_L, I thought you could write directly to a device "sda" etc using dd
06:20 PM phipli: so you could write 5M of ff to a physical disk
06:20 PM phipli: not something I've needed to do...
06:21 PM phipli: http://how-to.wikia.com/wiki/How_to_wipe_a_hard_drive_clean_in_Linux
06:21 PM phipli: ?
06:22 PM phipli: any use?
06:23 PM Tom_L: ok i got it, thanks
06:24 PM Tom_L: probably not one you wanna use on a daily basis
06:25 PM phipli: to warn you, I am 6 pints down...
06:25 PM phipli: although on the plus side I'm wearing a tux t-shirt
06:25 PM Tom_L: just don't spill any
06:25 PM phipli: spilt it all in my belly already
06:26 PM * JT-Shop-2 is on his second glass of vino
06:26 PM JT-Shop-2: I only drink 1 beer per day...
06:27 PM phipli: I met up with my old boss to catch up after work
06:27 PM phipli: but bumped into someone else on the way home afterwards
06:27 PM phipli: so kind of did two trips
06:29 PM JT-Shop-2: at the pub?
06:30 PM phipli: went to one pub, dropped into work to liberate some of the surplus scones on the way back just as someone was leaving... they wanted to go to the pub...
06:30 PM phipli: went to the other pub...
06:31 PM phipli: (my work does "payday treats" - they give us themed foodstuffs to celebrate each payday (today)
06:31 PM phipli: this time it was scones)
06:31 PM phipli: they bought too many
06:31 PM phipli: I helped out
06:31 PM JT-Shop-2: cool
06:31 PM JT-Shop-2: how often is payday?
06:31 PM phipli: monthly
06:31 PM phipli: 28th, or last working day before
06:32 PM JT-Shop-2: a festive occasion for sure then
06:32 PM phipli: food is always welcome
06:32 PM JT-Shop-2: how are your birds doing?
06:32 PM phipli: the older ones are being really mean to the lovely speckeldy one
06:32 PM phipli: I've been telling them off using a water spray
06:32 PM phipli: and they hate me for it
06:33 PM phipli: I have some chicken glasses, but don't have the heart to fit them
06:33 PM phipli: considering making a second run
06:33 PM phipli: yours?
06:34 PM JT-Shop-2: they are doing good, a friend put blinders on one of hers that fit in the nostril and stop pecking
06:35 PM JT-Shop-2: mine are spoiled for sure, I'm sprouting wheat in the run now
06:35 PM phipli: I worry that it will make them struggle to eat
06:35 PM JT-Shop-2: they get one per day
06:35 PM phipli: I'd rather distract them, but I'm away too much of the day
06:36 PM JT-Shop-2: doesn't seem to have any negative effects. separation works as well
06:39 PM phipli: right
06:39 PM phipli: should probably head to bed. long weekend ahead
06:39 PM JT-Shop-2: time to start some bubbles and squeak or something for dinner
06:39 PM JT-Shop-2: goodnight
06:39 PM phipli: we have a three day weekend and I'm needing to visit both our sets of parents
06:39 PM JT-Shop-2: if you want to see my code I can email it
06:40 PM phipli: I'd be interested
06:40 PM JT-Shop-2: I'll shoot it over in the morning
06:40 PM phipli: glad you guys know what bubble and squeak is :)
06:40 PM phipli: anyhow
06:40 PM phipli: night folks
06:40 PM JT-Shop-2: night
06:58 PM hazzy-dev: Latency does seem better with the new kernel, been using the PC normally far a few hours and it's at 25729, it used to get to about 75000
06:59 PM hazzy-dev: This is an old Lenovo T510 laptop with a 2.4GHz i5
06:59 PM pcw_mesa: what CPU?
07:03 PM pcw_mesa: also seems ok on those cheap J3355 CPUs (kind of J1800 replacement):
07:03 PM pcw_mesa: http://freeby.mesanet.com/3355preempt.png
07:10 PM pcw_mesa: ( though RTAI is noticeably better on the J3355 = ~25 usec )
07:35 PM Tom_L: not on this J1900
07:35 PM Tom_L: RTAI is probably ok on it though
07:44 PM pcw_mesa: I want to try the J3455 (four core version) but I have so many MBs...
07:44 PM pcw_mesa: also the J5005 which I think is the current fastest one in the series
08:32 PM Tom_L: managed to update grub with the old kernel..
08:33 PM Tom_itx: https://unix.stackexchange.com/questions/198003/set-default-kernel-in-grub?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa
08:33 PM Tom_L: in case anybody needs it
09:12 PM hazzy-dev: CaptHindsight: Working on the Corvair floors this evening. Got the lace cut out on rear passenger side and new floor almost ready to tack in
09:12 PM hazzy-dev: https://i.imgur.com/qNLYSgC.jpg https://i.imgur.com/49RgCWF.jpg https://i.imgur.com/3BxgSXy.jpg
09:13 PM hazzy-dev: Trying to make do with a 2x4 and a dead blow instead of a break ....
09:15 PM hazzy-dev: Before I tack it in I am going to repair the transmission linkage tunnel and patch up the rust in the transverse beam thing
09:20 PM * hazzy-dev gets a mug of that hot dark brown brew to counteract that cold light brown kind
