12:00 AM SpeedEvil: Are tehre any other alloys with sodium that approach structural usability?
12:04 AM SpeedEvil: Clearly not so great in air.
12:04 AM SpeedEvil: https://en.wikipedia.org/wiki/AlBeMet - neat
12:05 AM flyback: eww
12:05 AM flyback: beryllium
12:06 AM SpeedEvil: Alas, aliexpress does not have berylium powder
12:07 AM flyback: uh cause it's toxic as fuck
12:07 AM flyback: that's why
12:07 AM CaptHindsight: Metal-doped sodium aluminium hydrides as potential new hydrogen storage materials
12:07 AM flyback: asbestus part II
12:09 AM fragalot: hi
12:10 AM CaptHindsight: sodium-potassium alloys
12:11 AM CaptHindsight: https://www.americanelements.com/beryllium-powder-7440-41-7
12:12 AM CaptHindsight: http://www.espimetals.com/index.php/944-msds/beryllium-powder/963-beryllium-powder
12:12 AM CaptHindsight: https://www.alibaba.com/showroom/beryllium-powder.html
12:13 AM CaptHindsight: SpeedEvil: I'll be happy to perform any alibaba searches for you :p
12:14 AM fragalot: lol
12:16 AM CaptHindsight: some papers on sodium lead alloys about as well
12:18 AM CaptHindsight: https://books.google.com/books?id=JM0u1vwrS5UC&pg=PA16&lpg=PA16&dq=sodium+alloys&source=bl&ots=VzQBbCgFZo&sig=ACfU3U0fiTld_ZqW--LNQGveposxIMtGUw&hl=en&sa=X&ved=2ahUKEwjyrNmAr5fgAhUCyYMKHcChAjc4FBDoATAEegQIBRAB#v=onepage&q=sodium%20alloys&f=false
12:23 AM SpeedEvil: Odd, that diddn't work.
12:24 AM SpeedEvil: CaptHindsight: yeah - I've been idly wondering about that for battery use
12:24 AM SpeedEvil: low performance, but quite cheap and very available
12:25 AM SpeedEvil: liquid phase
12:26 AM CaptHindsight: lots of papers on liquid phase for batteries
12:30 AM CaptHindsight: https://www.youtube.com/watch?v=XPUuF_dECVI nice professor, he actually explains things in several different ways
01:53 AM Jymmm: CaptHindsight: how long till we see this at ikea? https://www.youtube.com/watch?v=QgUWd_U2P1w
01:55 AM Deejay: moin
02:01 AM CaptHindsight: Jymmm: Russian Epoxy very strong
02:02 AM CaptHindsight: https://www.imdb.com/title/tt0075860/ close encounters look so dated
02:02 AM Jymmm: CaptHindsight: cutting and deburring russian alum tubing... nuts
02:02 AM CaptHindsight: haven't seen it in years
02:03 AM CaptHindsight: no really crazy about the denim
02:03 AM CaptHindsight: the pieces of aluminum are interesting
02:03 AM Jymmm: I have close encoutners on dvd =)
02:03 AM CaptHindsight: I was just flipping through the channels
02:03 AM CaptHindsight: it's the cloud scene where they land
02:04 AM Jymmm: 7.7 rating from 164K pl =)
02:04 AM Jymmm: people*
02:05 AM CaptHindsight: Spielberg
02:06 AM Jymmm: geeze, search 'star wars' on imdb
02:40 AM sensille: Loetmichel: my first go at 2.5D: https://i.imgur.com/u0wopR9.jpg
02:48 AM Loetmichel: sensille: niice
02:49 AM Loetmichel: but thats 3d. 2.5d would be if it only has a few discrete "steps"
02:49 AM Loetmichel: not a smooth curve
02:49 AM sensille: oh. i thought 2.5d is everything i could do with that machine
02:50 AM sensille: 3d would need 4 or 5 axis
02:51 AM sensille: it took 3 hours
02:52 AM Loetmichel: hmm, anybody has a 3dfile for printing for a Mailbox lock replacement? Some "joker" thought if funny to pur half a bottle CA glue into our paper towel dispenser lock... A simple handle/knob instead of the key would be sufficient... -> http://www.cyrom.org/palbum/main.php?g2_itemId=17277&g2_imageViewsIndex=1
03:14 AM sensille: i used a ball end mill for that. the problem is that i have to go one radius into the spoil board
04:39 AM jthornton: morning
04:40 AM Wolf__: morning
04:46 AM XXCoder: morning
04:47 AM jthornton: 17°F and the chickens got up at 3:57AM this morning
04:49 AM Loetmichel: grumpf. mini lathe dead. an aluminium chip found its way onto the speed controller... bridged 230Vac onto the5V dc for the controller... new board: 99eur. new machine: 300 eur... maan, how can that be that the controller is open to the enviroment when it sits in the chassis below the machine? -> https://www.sieg-machines.de/Steuerplatine-C0
04:50 AM XXCoder: geez. maybe thats excuse to make it linuxcnc cnc lathe
04:50 AM CNC_Brian: Chicago weather has made it to the news in the UK
04:52 AM XXCoder: fun
04:52 AM Wolf__: 5°F here in the DC area
04:52 AM Wolf__: and I woke up to the boiler in shutdown mode…
04:53 AM XXCoder: 33f here
04:53 AM XXCoder: wow! monday temperate crashes
04:53 AM XXCoder: and sleet on sunday, and monday snow, first snow for the year
04:54 AM XXCoder: it mkight be cold enough that its not "snow dont like floor" type snow
04:54 AM Loetmichel: XXCoder: i doubt it would be worth it. maybe get a new slightly bigger lathe on company money... considering that machine is my private one that sat in the company for the last 2 years ;)
04:54 AM CNC_Brian: That board dosnt look very complicated
04:54 AM XXCoder: lol ok
04:54 AM XXCoder: whats your plan with now junk lathe
04:54 AM CNC_Brian: Probably get away with replacing the semi conductor devices.
04:54 AM XXCoder: your site has certification issues
04:54 AM XXCoder: oh not your site
04:55 AM Loetmichel: CNC_Brian: it has a microcontroller on it. i doubt the manufacturer would send you the code ;)
04:55 AM XXCoder: wonder if microcontroller is fine
04:55 AM CNC_Brian: Ah cant see that from the pic
04:56 AM Loetmichel: its dead
04:56 AM Loetmichel: all semiconductors on that board are 0 ohm
04:56 AM Loetmichel: already checked
04:56 AM CNC_Brian: Also it may have killed anything attached
04:56 AM XXCoder: dang
04:59 AM Wolf__: …you might be a tech geek (and lazy) when you break out a flir camera to check to see if the baseboard heat has come back on yet
04:59 AM XXCoder: lol
05:01 AM Wolf__: wow window curtain is reading a 3.1°C spot on it where the air is leaking in lol
05:01 AM CNC_Brian: Do you know what functions the board performs? Maybe get external motor controller, etc.
05:03 AM rmu: it looks like it could be some sort of phase angle speed controller
05:11 AM CNC_Brian: I removed the limit switch on my power feed as it was in the way of a clamp. Blew up something similar.
05:12 AM CNC_Brian: Replaced it with a KBIC-240
05:22 AM Tom_L: 16F Hi 45
05:24 AM XXCoder: Tom_L: it will actually get cold here next monday lol
05:24 AM XXCoder: 22f
05:24 AM Loetmichel: CNC_Brian: its just a speed controller for a 230V DC motor. with additional lock for Estop, guard closed and overcurrent. not that big a deal
05:24 AM XXCoder: 44f right now tho
05:24 AM Loetmichel: but if i can get my boss to buy the slightly bigger version for me because it being "dead" i would be glad. its sitting at the company for two years now and is my private one ;)
05:25 AM CNC_Brian: Hass Mini Mill ??
05:25 AM CNC_Brian: $30000 +
05:25 AM Loetmichel: thats a few zeroes to much ;)
05:25 AM XXCoder: 4 too many? ;)
05:26 AM Loetmichel: i thought something like this: https://www.ebay.de/itm/0618-Mini-Metalldrehmaschine-Drehmaschine-Tischdrehmaschine-220V-digital-NEWEST/252813787114
05:26 AM Loetmichel: 2 to many
05:33 AM syyl: i still try to figure out how to shoehorn a haas minimill in my shop, CNC_Brian ;)
05:34 AM Wolf__: surprised that you haven’t build a mini minimill
05:34 AM syyl: haha
05:35 AM XXCoder: need to mill mini mill parts and finish build so can repeat it at smaller size for mini minimill ;)
05:35 AM Wolf__: like 1:4 scale copy of a VMC lol
05:36 AM syyl: there is that guy who build a small scale fadal vmc
05:36 AM CNC_Brian: I would get a pre-owned larger machine if you use it daily or even weekly on work stuff
05:36 AM Wolf__: really one of the hard parts you already have, that spindle you have on your router table lol
05:39 AM Wolf__: got my lathe back together last night so now I can finally do some things I have been wanting to work on https://i.imgur.com/Ip4MdWj.jpg
05:39 AM Wolf__: next big task is to tackle the motor swap on my mill…
05:42 AM Wolf__: I’m liking the VFD setup, rotary switch gives me 60hz, manual frequency knob and 30hz and 10hz jog button
05:56 AM CaptHindsight: CNC_Brian: only -24F now, was watching it on the BBC UK feed earlier
05:56 AM CaptHindsight: don't think we'll break the record of -27F
05:56 AM CNC_Brian: Get your short on :-)
05:57 AM CaptHindsight: it's not too bad out of the wind, in the wind it feels like a belt sander to the face
05:59 AM CaptHindsight: skunkworks seems to be in the center of it, -40F -40C
06:00 AM XXCoder: heh he can make instant snow using boiling water
06:01 AM SpeedEvil: Such fun that.
06:01 AM SpeedEvil: Especially all the fail videos.
06:02 AM CaptHindsight: https://www.wunderground.com/personal-weather-station/dashboard?ID=KWIBLAIR4
06:04 AM XXCoder: surpised that works, Wu was closed down
06:05 AM XXCoder: same time its their own site nm
06:53 AM XXCoder: interesting! jthornton check it out https://www.youtube.com/watch?v=2QBc59YZYxA
06:57 AM jthornton: cool
06:59 AM XXCoder: chart shows pretty good jump in airflow.
06:59 AM gregcnc: that's been around a long time now
06:59 AM Loetmichel: XXCoder: smoothing inside of manifolds by pressing goo with grinding compound thru?
07:00 AM XXCoder: loet with huge pressure apparently yeah greg apparently knows about it
07:00 AM XXCoder: gregcnc: not surpised, theres always something i dont know about :)
07:00 AM gregcnc: I didn't know but the process was patented in 1970
07:00 AM Loetmichel: its old hat
07:00 AM Loetmichel: but interesting nontheless
07:01 AM gregcnc: I don't know much about it, some engine guys say the smoothness is detrimental to performance and still prefer hand grinding
07:02 AM gregcnc: but to keep a stock manifold like that, not many options
07:03 AM Jymmm: Even shows test data
07:04 AM Loetmichel: gregcnc: back in the "golf 1 tuning" days we did that with a flex shaft and some flapper wheels
07:04 AM Loetmichel: and LOTS of elbow grease
07:05 AM Jymmm: Loetmichel: ...and beer
07:05 AM Loetmichel: https://www.amazon.de/dp/B0002SMO68 <- these things
07:05 AM Loetmichel: Jymmm: indeed ;)
07:06 AM XXCoder: and pizza and friends
07:06 AM gregcnc: yeah, I read a lot about engines, but don't play with cars
07:08 AM gregcnc: they had to set the railroad tracks on fire in Chicago it's so cold
07:08 AM gregcnc: it's news now, but they use it anytime it's below freezing
07:09 AM Jymmm: I just abuse cars... the speedo says 140 MPH and 8000 RPM, if it wasn't meant to do that all the time, they shouldn't put that!
07:09 AM XXCoder: greg i forgot where but they ran transit 24 hours because it keeps tracks clear so people can keep moving
07:09 AM XXCoder: normally close for few hours
07:10 AM Jymmm: It was -50 yesterday in canada, a friend turned on their defrost and cracked the windshield.
07:10 AM gregcnc: hmm
07:11 AM XXCoder: ouch
07:11 AM Loetmichel: Jymmm:my car says 150mph and the red starts at 5500rpm... still after less than 5 min of 142mph it starts overheating ;)
07:11 AM gregcnc: I saw a russian YT where they poured boiling water on a windshield expecting it to break and it didn't
07:11 AM XXCoder: jymm theres recipe to make defrost glass lemme see if can find
07:11 AM Loetmichel: gregcnc: car windshields are pretensioned
07:12 AM Loetmichel: and laminated
07:12 AM Loetmichel: they dont break easy
07:12 AM Jymmm: Loetmichel: overheating? Nah, that's just "warming up" ;)
07:13 AM XXCoder: https://www.youtube.com/watch?v=95V-jXt262A found
07:13 AM gregcnc: i know, interweb is full of the boiliing water on windshield joke assuming it will crack though...
07:13 AM Jymmm: gregcnc: it potentially could
07:13 AM XXCoder: uses rubbing alchol and water. not hot water
07:13 AM XXCoder: it lowers melt temperate a lot
07:13 AM Loetmichel: Jymmm: Opel bought the 2.5l diesel from BMW... didnt have the room to fit a sufficient radiator though
07:14 AM Loetmichel: so it overheats at full throttle in summer
07:14 AM Loetmichel: after a few minutes
07:14 AM gregcnc: oops
07:14 AM Jymmm: Loetmichel: toss 3 or 4 on the roof
07:14 AM gregcnc: the window juice in the car is already methanol
07:14 AM gregcnc: is IPA that much better?
07:15 AM XXCoder: good question
07:15 AM XXCoder: maybe it pushes melt temperate that much more?
07:16 AM gregcnc: dam winduhs updates are bricking a box. I thought it was trying to install W10 but now I have no idea.
07:16 AM XXCoder: pure ethanol freezes at -173 degree, methanol -143
07:17 AM XXCoder: windblows updates
07:17 AM gregcnc: vodka
07:17 AM XXCoder: rubbing alchol -128f
07:18 AM gregcnc: so denatured alcohol would be better
07:18 AM XXCoder: looks like
07:18 AM Loetmichel: depends
07:19 AM Loetmichel: maybe rubbing alcohol is better at diluting water?
07:19 AM Loetmichel: so ripping the ice crystals up?
07:19 AM Jymmm: ...and rubber and plastics too
07:20 AM XXCoder: thats also possible
07:20 AM XXCoder: well time to go bed laters
07:20 AM Loetmichel: it definetly is less volatile and evaporates more slowly
07:20 AM Loetmichel: so thats a plus for IPA
07:20 AM Loetmichel: against ethanol
07:21 AM gregcnc: anyone tried those wiper blade knives? I see them advertised lately, and was something I wanted to try years ago
07:22 AM Loetmichel: whats that?
07:22 AM gregcnc: but methanol/water mixtures actually do much better
07:22 AM gregcnc: as far as freezing point
07:24 AM gregcnc: ecocut-pro.de
08:33 AM PL7icnc: Good DAY All
08:33 AM PL7icnc: Sunny Here
08:34 AM PL7icnc: Loetmichel, Sind Sie Hier ?
08:34 AM Loetmichel: sure
08:36 AM PL7icnc: Loetmichel, Ich War bei der familie von Herrn Sammel
08:37 AM PL7icnc: Man Hat mir eine Maschine Mitgegeben und den Hauptrechner
08:37 AM PL7icnc: ist garnichtmal so weit weg
08:38 AM MacGalempsy: yo
08:38 AM PL7icnc: Ich hab den Man auch sicherlich schonmal Getroffen am See
08:38 AM PL7icnc: Hi MacGalempsy
08:38 AM PL7icnc: I Will Upload all the Videos if Checked from the Former ichGucksLive
08:39 AM Loetmichel: nice
08:39 AM PL7icnc: https://www.youtube.com/channel/UCGuJsIoXW-exBAwdn38dXow/videos
08:40 AM MacGalempsy: changing your nick, or forget that password?
08:40 AM PL7icnc: i checked Out more then 500 Videos but very old Hardy Linuxcnc 2.2.5 or so
08:41 AM PL7icnc: MacGalempsy, No Sir the Ich.. has Pased to HeAVEN
08:41 AM PL7icnc: RIP
08:42 AM MacGalempsy: oh, sorry to hear that. condolences
08:48 AM PL7icnc: i dident visite hos grave so Far
08:48 AM PL7icnc: Does someone Here Know as he have seen the 4th axis mashine he Build runnning
09:01 AM PL7icnc: im off
09:48 AM Loetmichel: hihi, who said it a while ago that a CNC mill cant be used "mobile"? i just found a picture that proves otherwise.. ;) -> http://www.cyrom.org/palbum/main.php?g2_itemId=12129&g2_imageViewsIndex=1
09:52 AM TekniQue: lol wtf
09:53 AM Loetmichel: company needed a few prototypes... so i packed my selfbuilt CNC into the trunk... ;)
09:53 AM Loetmichel: i just was to lazy to get it out ;)
09:54 AM Loetmichel: as it was summer...
09:54 AM rmu: on-demand on-site machining
09:56 AM Loetmichel: yes
09:57 AM gregcnc: for your regular wage?
09:57 AM Loetmichel: yes
09:57 AM gregcnc: that needed a contract
09:57 AM Loetmichel: took me the better part of three years to convince the boss to buy that first CNC 6040...
09:58 AM Loetmichel: because my private CNC started to wear out ;)
09:59 AM Loetmichel: he DID let me "refurbish" it on company time with company paid parts though
09:59 AM Loetmichel: my own one
10:20 AM FinboySlick: Loetmichel: It's a cute little machine. Your work machine is a gantry machine, right?
10:21 AM Loetmichel: FinboySlick: a CNC 6040, correct
10:22 AM FinboySlick: Are those home-made dovetails on this one?
10:22 AM Loetmichel: nope
10:22 AM Loetmichel: 20mm round steel with ball bearings running on them
10:23 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=14034&g2_imageViewsIndex=1
10:23 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=14037
10:23 AM Loetmichel: see=
10:23 AM Loetmichel: ?
10:25 AM FinboySlick: http://www.cyrom.org/palbum/main.php?g2_itemId=14007 That's a sprocket/gear from fischertechnik, no?
10:25 AM FinboySlick: Oh I loved my fischertechnik sets as a kid. I had the compressor trailer and a snow dozer.
10:26 AM Loetmichel: yes it is
10:27 AM Loetmichel: its nice for testing stuff to have a gear/sproket and chain that has clip on links
11:48 AM fragalot: 'sup
11:49 AM ziper: hi
11:49 AM fragalot: https://www.youtube.com/watch?v=Ya1iDTix8Js
11:49 AM ziper: I think my rails are slightly not parallel
11:50 AM fragalot: everyone needs this practical device in their homes
11:50 AM ziper: so that as the gantry traverses the axis they twist and dig in
12:46 PM FinboySlick: fragalot: He's completely mad doing that in the UK. Who's taking bets on how long before he gets in trouble for fat-shaming?
12:47 PM fragalot: lol
12:50 PM FinboySlick: fragalot: It's the little details. Notice how he actually drilled the carrot to put it on a string?
12:51 PM fragalot: he's known for putting biscuits into his lathe to make them fit in his mug
12:52 PM FinboySlick: You gotta envy him for being able to make a living out of goofing off in the shop.
12:57 PM fragalot: brilliant.
12:58 PM fragalot: we had an energy shortage here in belgium for winter, with a lot of prep being made with emergency cut-off plans & stuff
12:58 PM fragalot: so naturally what we've started doing, is exporting 1GW to the UK this week
12:59 PM FinboySlick: Probably the EU trying to get as much cash out of the UK while they can ;)
12:59 PM fragalot: :D
12:59 PM FinboySlick: "See? You can't leave, else you'll run out of power.
01:02 PM gloops: probably because its twice the selling price in the UK, Belgium can buy some from Poland now
01:03 PM gloops: i see Italy is now in recession, Italy France and Germany in recession, UK leaving in 2 months
01:07 PM fragalot: we can buy from .NL, .DE and .FR
01:07 PM FinboySlick: gloops: The EU's super-efficient management will get all of that sorted out by next week, I'm sure.
01:07 PM fragalot: but the other month in the news they said that even if we maxed out that capacity, we still needed 750MW to supply internal demands
01:08 PM fragalot: but I guess they must have finally fixed at least one of the nuclear plants recently
01:08 PM gloops: FinboySlick yes its like a well oiled machine
01:09 PM gloops: hows the wind situation in Belgium?
01:10 PM fragalot: http://www.meteo.be/meteo/view/en/65239-Home.html
01:12 PM gloops: i mean, is it windy enough to generate meaningful amount of energy, we seem to be putting a lot into wind
01:13 PM fragalot: wind has been negligible today
01:13 PM fragalot: http://www.elia.be/en/grid-data/dashboard
01:13 PM gloops: wind still less than 5% in belgium
01:14 PM gloops: mainly gas and nuclear - and oil
01:14 PM fragalot: it was 655MW at midnight, but it's down to almost nothing now
01:14 PM fragalot: yeah
01:14 PM fragalot: the gas plants are the reserve, the neglected nuclear are the baseline
01:15 PM fragalot: we have 7 plants, only 1 was online for most of winter
01:15 PM fragalot: polticians have made it a priority to shut them down for the past 30 years now without offering alternatives
01:16 PM fragalot: and a french company bought them a few decades ago too
01:16 PM fragalot: but since they were going to have shut down several times now... they haven't really invested in them properly
01:16 PM FinboySlick: Now that last bit is the real catastrophe ;)
01:16 PM fragalot: FinboySlick: it was :-)
01:16 PM gloops: oil is at over 40% not sure if that includes vehicles though
01:16 PM gloops: dont think so
01:17 PM fragalot: gloops: the elia site is electrical power only
01:17 PM fragalot: liquid fuel for power is nearly non-existant, apart from backup gennies
01:17 PM gloops: https://en.wikipedia.org/wiki/Energy_in_Belgium
01:18 PM fragalot: gloops: http://www.elia.be/en/grid-data/power-generation/generating-facilities
01:18 PM fragalot: liquid fuel: 1.48%
01:18 PM FinboySlick: Is wind really that beneficial though? What we have here seems very expensive in terms of maintenance.
01:18 PM fragalot: FinboySlick: it's kept alive with government subsidies here
01:19 PM gloops: wiki figures must include vehicles then
01:19 PM fragalot: even though I believe it doesn't ACTUALLY need it
01:19 PM FinboySlick: Yeah, but that can't be economically viable long-term.
01:19 PM fragalot: and a lot of the maintenance required is done "because it generates subsidy revenue"
01:20 PM FinboySlick: We manufacture a lot of impellers here. I'm pretty sure some of them end up in europe.
01:48 PM CaptHindsight: anyone here work with the closed source config tools for Linux like Ansible?
01:48 PM CaptHindsight: or similar
01:53 PM FinboySlick: Wish I could help but haven't. Is that like cPanel?
01:56 PM * Jymmm kinda wants one (sorta)... https://www.aliexpress.com/item/Smart-Children-Watch-GSM-GPRS-Kids-Wrist-Watch-Y21S-2G-GSM-Tracker-No-GPS-Module-Anti/32864743466.html
01:57 PM fragalot: Jymmm: to put on the chickens?
01:58 PM CaptHindsight: FinboySlick: yes, only closed source
01:58 PM Jymmm: fragalot: No chickens, but there are wild peacocks
01:58 PM FinboySlick: CaptHindsight: I only know of the web guys here using cPanel
01:58 PM CaptHindsight: I can't imagine how they can be stable unless tied to some very exact version of some linux distro
01:58 PM Jymmm: fragalot: JT is chicken guy
01:59 PM fragalot: you both start with a J.
01:59 PM fragalot: how am I supposed to know the difference
01:59 PM fragalot: :D
02:00 PM Jymmm: fragalot: you have 1 in 26 chance =)
02:00 PM Jymmm: CaptHindsight: what are you attempting to accomplish?
02:05 PM FinboySlick: CaptHindsight: as far as I'm aware, cPanel is pretty tied to CentOS.
02:10 PM CaptHindsight: Jymmm: find out why people use those tools, the closed source versions
02:11 PM FinboySlick: I think there are two parts to that: People who want a bunch of pre-made recipes for system management and people who think tools are better when you pay for them.
02:12 PM CaptHindsight: yeah, pay to complain to
02:13 PM CaptHindsight: the 2nd group seems to need a crutch to use Linux
02:13 PM CaptHindsight: and want somebody else to fix their issues
02:13 PM FinboySlick: Well, given the brainpower of our web team, I assure you that the $20/mo they pay for cPanel is absolutely necessary.
02:14 PM gloops: https://www.ebay.co.uk/itm/XYZ-Proturn-350-CNC-Lathe/312450457992?
02:14 PM Jymmm: CaptHindsight: Same reason ppl use M$
02:15 PM CaptHindsight: Jymmm: funny, they seem to be M$ users that use Linux in some way
02:15 PM Jymmm: CaptHindsight: =)
02:16 PM gregcnc: what are you going to turn gloops?
02:17 PM gregcnc: why does it take 10x as long for winduhs to undo an update as it does to crash it?
02:17 PM gregcnc: maybe 100x
02:17 PM CaptHindsight: Jymmm: been coming across "business" people that claim to be looking for Linux admin help, but thats really not what they are looking for
02:18 PM Jymmm: CaptHindsight: then what are they looking for?
02:18 PM CaptHindsight: Linux unicorns
02:19 PM Jymmm: CaptHindsight: ...and $11.50/hr, part time, 6 hours a week, and on call?
02:19 PM FinboySlick: That's typically what happens. Microsoft people who believe "Linux is better" but have no idea what that really means.
02:19 PM CaptHindsight: their M$ staff can't figure out how to make Linux work with all those closed source tools they have been buying
02:19 PM Jymmm: heh
02:19 PM CaptHindsight: FinboySlick: bingo
02:20 PM CaptHindsight: tastes better and less filling
02:20 PM FinboySlick: There's a hint of sympathy though. When you come from an MS world, it's very hard to wrap your head around the notion that the best, most expensive 'solution' doesn't serve you better.
02:20 PM Jymmm: Thye only buy what they feel they know and can support
02:21 PM CaptHindsight: they don't even know what questions to ask
02:21 PM Jymmm: Eh, sometimes.
02:21 PM FinboySlick: We bought a windows-only shop last year... It's still hard for me to fathom the hoops they jump through to perform their day to day tasks.
02:22 PM CaptHindsight: these co's seem to be voip, website, and other online services that I haven't made out yet
02:22 PM * fragalot moves an image in FinboySlick's word document
02:23 PM gregcnc: that's just wrong
02:23 PM Jymmm: I know nothing about AS400, but have to support connectivity. IBM's client solutaion was something like $200 per user/per year. I did some reasearch and found a simpler to use/install/maintian solution for $400 site license =)
02:24 PM FinboySlick: Management is trying to improve the situation and comes to me for answers. It's hard for me to explain that these guys don't really know how to sysadmin. They have a catalog of pre-made solutions and they do their best to cram whatever problem they have into one of those boxes.
02:24 PM CaptHindsight: yeah thats what they appear to be doing
02:24 PM fragalot: FinboySlick: fileserver down? better dump it all into sharepoint sites
02:25 PM FinboySlick: fragalot: You hit it surprisingly close to the mark.
02:25 PM CaptHindsight: no wonder they can't find a Linux admin after 4 months of searching
02:25 PM Jymmm: oh gawd... sharepoint
02:25 PM CaptHindsight: how they think
02:25 PM fragalot: Jymmm: it's only mildly buggy
02:25 PM CaptHindsight: but they are all IT wizards
02:26 PM Jymmm: fragalot: Yeah? you think so? just try to LINK a share with someone =)
02:26 PM CaptHindsight: why things are so broken
02:26 PM FinboySlick: CaptHindsight: Again, it's a matter of perspective. Compared to their users and their typical contemporary, they are.
02:26 PM fragalot: Jymmm: bet it's just as easy as changing the site icon
02:26 PM fragalot: Jymmm: or adding a row to a table
02:26 PM CaptHindsight: FinboySlick: sprinkle on some arrogance and they are IT gods
02:27 PM Jymmm: fragalot: It's much easier to just install linux =)
02:27 PM FinboySlick: The two windows admin that we acquired with the company aren't that bad, but you definitely summed up the .NET programmer that came along.
02:27 PM CaptHindsight: Jymmm: they don't support that solution
02:27 PM fragalot: Jymmm: except "linux" doesn't fix the problem by itself
02:28 PM Jymmm: fragalot: yes, it actually does =)
02:28 PM FinboySlick: The guy who came to me asking why everybody told him that leaving an MS-SQL port open to the wide internet is a bad idea... And then argued with me when I answered.
02:28 PM fragalot: granted, it opens access to actually stable tools, but just putting a debian livecd into your server isn't going to fix it :P
02:28 PM fragalot: you still need to install at least wordpress >.>
02:28 PM * fragalot runs
02:29 PM CaptHindsight: https://www.youtube.com/watch?v=fAktV72_nnE made the mistake of listening to this before bed
02:30 PM Vq: fragalot: Why don't you open up telnet with an empty root passwd right away? That's really handy.
02:31 PM fragalot: Vq: because IT blocks all non-http protocols
02:31 PM Vq: or rsh...
02:31 PM fragalot: including https
02:32 PM CaptHindsight: ssh open by default on new installs
02:32 PM Jymmm: ssh isnt even insallted
02:32 PM CaptHindsight: Scientific Linux
02:33 PM CaptHindsight: it's like a shared Linux for nosey sys admins
02:33 PM Vq: fragalot: ok, wordpress might be the way to go then as long as you remember to run it as root.
02:33 PM FinboySlick: ssh being open by default isn't necessarily bad so long as it isn't started with a stupid config. Defaults are pretty sane.
02:33 PM CaptHindsight: password = password
02:35 PM CaptHindsight: Automation Engineer most likely is now a software admin position with no mechanical systems involved
02:35 PM fragalot: hunter12
02:35 PM CaptHindsight: I like how "business" people hijack terms
02:38 PM fragalot: IoT!
02:38 PM fragalot: and blockhains
02:38 PM CaptHindsight: heh
02:38 PM CaptHindsight: AI
02:38 PM CaptHindsight: machine learning
02:38 PM fragalot: 3D printing
02:39 PM fragalot: no need to machine things, just hit print and it comes out better
02:39 PM CaptHindsight: more better
02:41 PM CaptHindsight: we were working with a defense contractor to port RTAI to a certain distro
02:42 PM CaptHindsight: not sure if any of them there understood how Linux works
02:42 PM CaptHindsight: I don't know how they actually make their products work
02:44 PM CaptHindsight: gregcnc: oh well we fell just short of the record low
02:44 PM CaptHindsight: skunkworks: did you guys break your all time low record?
02:52 PM gregcnc: some relief this weekend
02:52 PM CaptHindsight: will be nice to outside again without the feeling of a belt sander to the face
02:53 PM gregcnc: yeah i have to check if the hobbytown is still open
02:54 PM CaptHindsight: I passed it yesterday
02:54 PM gregcnc: they're going out of business
02:54 PM CaptHindsight: didn't look that close
02:54 PM fragalot: CaptHindsight: https://i.imgur.com/6r2bzek.mp4
02:54 PM CaptHindsight: hoffman estates is next close
02:54 PM gregcnc: right
02:55 PM CaptHindsight: hah
02:55 PM FinboySlick: fragalot: Turning boiling water into snow gone wrong?
02:55 PM fragalot: FinboySlick: That is indeed what that staged clip implies
02:56 PM CaptHindsight: it doesn't freeze that fast anyway
02:56 PM CaptHindsight: fun
02:56 PM gregcnc: even without sound you can tell how fake it was
02:56 PM FinboySlick: CaptHindsight: Actually, it's surprisingly fast but it probably has to be better conditions.
03:13 PM CaptHindsight: https://imgur.com/gallery/tTBwGBX plausible
03:17 PM fragalot: https://i.imgur.com/ILzCOXV.png it's hair gel
03:19 PM CaptHindsight: are there any automation tools for writing ladder logic?
03:19 PM CaptHindsight: it's already abstract
03:20 PM FinboySlick: fragalot: Not in the (fictional) case you linked.
03:22 PM fragalot: CaptHindsight: define automation tools?
03:22 PM CaptHindsight: https://youtu.be/rq6z1hShFcE?t=256 MarcelineVQ to difficult a task for a current Bot with PLC
03:22 PM CaptHindsight: to/too
03:23 PM fragalot: do you want to automate the ladder part, or a tool to enter the ladder logic into?
03:23 PM CaptHindsight: yes
03:23 PM fragalot: You're worse than your customers >.>
03:23 PM CaptHindsight: I want to be even more abstract
03:23 PM CaptHindsight: just the idea of what i want to do, then have the AI figure the rest
03:24 PM fragalot: what's this "training" you speak of,
03:24 PM CaptHindsight: VHDL for PLC's
03:25 PM CaptHindsight: with Python for "flexible" part of the programs
03:25 PM * fragalot is actually doing that last part on his microcontroller platforms
03:25 PM fragalot: ItWorks (tm)
03:26 PM fragalot: and it stops the engineers bugging me for firmware updates for inane add-ons
03:27 PM CaptHindsight: never like ladder myself
03:28 PM fragalot: ladder was acceptable back when PLC's were basically programmable relays
03:28 PM CaptHindsight: especially when it came to shift registers and counters
03:28 PM CaptHindsight: count 51246
03:28 PM CaptHindsight: thanks
03:28 PM CaptHindsight: yeah for simple stuff
03:29 PM fragalot: "please make a sinusoidal move, synchronized with this other axis"
03:29 PM fragalot: try doing that in ladder
03:29 PM CaptHindsight: not for complex state machines with multiple conditional inputs
03:29 PM fragalot: yeah..
03:29 PM CaptHindsight: I see attempts at it
03:29 PM fragalot: i've been there & done that on a low budget PLC
03:29 PM fragalot: it CAN be done, but by god it is awful to do
03:30 PM CaptHindsight: i got somebody so angry about 10 years ago that they flagged Linuxcnc on wikipedia for removal
03:30 PM fragalot: lol
03:30 PM CaptHindsight: they were a contractor for ITW programming a coiling machine or similar, was for wire
03:30 PM fragalot: i've even programmed conditional state machines on little HMI's using their built-in macro languages
03:31 PM CaptHindsight: the manager called me in to fix so I mentioned LCNC with some python and a few days....
03:31 PM fragalot: my office wall looked like this: https://proxy.duckduckgo.com/iu/?u=https%3A%2F%2Fmedia.giphy.com%2Fmedia%2Fl0IylOPCNkiqOgMyA%2Fgiphy.gif&f=1
03:32 PM XXCoder: lol
03:33 PM fragalot: CaptHindsight: is it me, or is everything in that audi video incredibly slow?
03:33 PM CaptHindsight: maybe it was slow to shoot the how it's made
03:34 PM CaptHindsight: I like the stitching
03:34 PM CaptHindsight: they all seem to copy Teslas motor design
03:34 PM fragalot: tesla did a proper job & released the patents
03:34 PM fragalot: why wouldn't they copy it
03:34 PM fragalot: its the one thing Tesla got right :P
03:35 PM CaptHindsight: is that why
03:35 PM CaptHindsight: saw another video of how goofy the Tesla chassis are
03:35 PM fragalot: goofy chassis, panel gaps, moisture issues,..
03:35 PM CaptHindsight: so tesla hired decent EE's but not ME's
03:36 PM fragalot: reliability issues, especially with the door locks
03:36 PM fragalot: and condensation in the lights
03:36 PM CaptHindsight: ask a few older auto maker engineers to come over and review
03:36 PM CaptHindsight: would have saved them millions
03:37 PM fragalot: but that is not the silicon valley way
03:37 PM CaptHindsight: "hey you can't be critical of what i designed"
03:37 PM fragalot: you need to look forward, not at history
03:37 PM CaptHindsight: hah
03:37 PM CaptHindsight: kids leading the kids
03:38 PM fragalot: CaptHindsight: have you ever looked into the stories of people that bought a 2nd hand car from Tesla?
03:38 PM CaptHindsight: haven't followed much of it at all
03:39 PM fragalot: you can request pictures, but never get any
03:39 PM fragalot: put down a downpayment of whatever amount it was
03:39 PM fragalot: have to send insurance papers over etc
03:39 PM XXCoder: and get volkwagon bettkle
03:39 PM fragalot: they sometimes deliver the car within a few months
03:39 PM fragalot: but the title can take up to a year
03:40 PM XXCoder: geez
03:40 PM fragalot: sometimes you get to talk to the same person twice
03:41 PM fragalot: https://www.youtube.com/watch?v=H8ro6kpKlw0
03:41 PM fragalot: little video series
03:43 PM CaptHindsight: there a video of a tesla refurbisher on motherboard
03:44 PM CaptHindsight: sop they opened up the motor patent and then fight to keep people from fixing their own tesla
03:44 PM CaptHindsight: they really sound crazy
03:44 PM fragalot: yup :-)
03:45 PM CaptHindsight: https://www.youtube.com/watch?v=NuAMczraBIM
03:45 PM CaptHindsight: Rogue Tesla Mechanic Resurrecting Salvaged Cars
03:45 PM fragalot: that's the same guy, Rich rebuilds
03:46 PM CaptHindsight: Right to repair
03:46 PM XXCoder: we need such law in usa
03:52 PM CaptHindsight: was watching the tractor vids
03:53 PM Deejay: gn8
03:54 PM CaptHindsight: what they need is an open source ECU and computer to swap out the factory crap
03:54 PM XXCoder: CaptHindsight: deere tractors?
03:54 PM CaptHindsight: but if the sensors have built in encryption and networking that might be more trouble than its worth
03:54 PM rmu: there should be a law against factory crap
03:54 PM XXCoder: one with crazy licensing stuff
03:54 PM CaptHindsight: XXCoder: yes
03:54 PM rmu: and crap factories
03:55 PM XXCoder: rmu: right to repair law. look it up, and try vote it in
03:55 PM XXCoder: it includes everything like phones that cant be opened to washers that have very expensive yet cheap to make parts
03:55 PM rmu: i'm on the wrong side on the pong, but if it comes up in europe, i will support it
03:55 PM rmu: s/pong/pond/
03:56 PM XXCoder: its going in europe faster than in usa
03:56 PM CaptHindsight: it's part of the DRM stuff that they all passed 15-20 years ago
03:56 PM XXCoder: yeah boy did they abuse digitial millenium laws
03:57 PM CaptHindsight: as paranoid as RMS is he's been right about much of this
03:57 PM CaptHindsight: in fact he underestimated how sneaky people might be in practice
03:57 PM CaptHindsight: hence the GPL3
03:57 PM rmu: i don't think the philosophy of the GNU project is paranoid
03:58 PM CaptHindsight: didn't mean the clinical definition
03:59 PM CaptHindsight: just his obsessive qualities about it
03:59 PM rmu: without GNU there would exist some BSD variants as niche things for research and OS nerds, and we would be stuck with mainly proprietary stuff
04:01 PM rmu: i think RMS tried to make the philosophy logically consistent (at least internally), and like with c++, one thing leads to the next, and then you get the mess with GPL2, GPL3, AGPL, LGPLx and the GFDLs
04:02 PM CaptHindsight: pay per listen by each ear, pay per view per eye, pay per ride per butt
04:03 PM CaptHindsight: and make it law
04:07 PM rmu: maybe in 100 years people like RMS will have become something like the amish people, completely refusing to use proprietary software, drm and hardware requiring binary blobs, and therefore subjecting themselves to a more or less segregated life
04:08 PM roycroft: hopefully in 100 years peope like rms will all be dead
04:08 PM roycroft: lord knows he smells like he's dead already :)
04:08 PM XXCoder: y0pu met rms in person?
04:08 PM XXCoder: *you
04:08 PM roycroft: actually, i haven't
04:08 PM roycroft: but i know several who have
04:08 PM roycroft: including a woman who dated him for a while
04:09 PM roycroft: and i had to make sure to always be upwind of her
04:09 PM Jymmm: Where can I get lipo packs from?
04:09 PM roycroft: your butt?
04:10 PM rmu: i met him and there was no smell problem. but AFAIK rms refuses to shower. in a sense, he is a "truely impossible human being"(tm) ;)
04:10 PM Jymmm: depleted, need replacements
04:10 PM CaptHindsight: brain wired for attention to certain details, personal hygiene not included
04:10 PM Jymmm: I am serious though, can't find them
04:10 PM CaptHindsight: lipo packs?
04:11 PM CaptHindsight: LiPo batteries?
04:11 PM Jymmm: like this https://cdn.sparkfun.com//assets/parts/1/1/4/0/1/13813-01.jpg
04:11 PM CaptHindsight: liposome
04:11 PM Jymmm: I need to replace some 8v ones

04:12 PM CaptHindsight: aliababababa
04:12 PM XXCoder: aliexpress
04:12 PM CaptHindsight: or do you need a store you walk into, ask a salesperson and trade in paper currency?
04:13 PM roycroft: if i knew i'd have given you a real answer, jymmm
04:13 PM Jymmm: ordering is fine, hobbyking all has connectors on them
04:13 PM Jymmm: https://hobbyking.com/en_us/catalogsearch/result/?cat=8338&q=lipo
04:13 PM roycroft: but since i didn't i was flippant
04:14 PM Jymmm: I just need the raw packs
04:14 PM CaptHindsight: i used to find them on aliababababa
04:15 PM CaptHindsight: no idea who stocks them in the USA
04:15 PM CaptHindsight: if you have a spec i try to search for at minimum charge
04:15 PM Jymmm: oh gawd, HK is being SO slow today =(

04:17 PM Jymmm: $55 ?!
04:17 PM Jymmm: I barely paid $24 for the while devicce and it has two of those
04:17 PM Jymmm: whole*
04:18 PM CaptHindsight: https://www.dhgate.com/wholesale/lipo+battery+cells.html

04:20 PM CaptHindsight: how manys amps hours?
04:20 PM Jymmm: CaptHindsight: those all have connecotors on them
04:21 PM CaptHindsight: have wire cutters?
04:21 PM Jymmm: It usually means they have extra casing on them as well, I have a size limitation
04:21 PM CaptHindsight: https://www.batteryspace.com/loosehipowerpolymercells.aspx
04:21 PM CaptHindsight: raw cells quit your bally aching and do some finger searchin
04:22 PM CaptHindsight: jeeeeeeeeeeeeeeeezzussss
04:22 PM Jymmm: Not necessarily "raw" but link I linked to
04:22 PM CaptHindsight: just fyi 2 x 3.7 = 7.4
04:24 PM Jymmm: I"m disassembling now...
04:27 PM `Wolf_: having a idea of size/mah would help on the suggestion process lol
04:28 PM `Wolf_: and the current needed
04:29 PM CaptHindsight: nah
04:30 PM CaptHindsight: just needs a bag of fresh electrons
04:32 PM `Wolf_: https://hobbyking.com/en_us/zippy-850mah-20c-single-cell.html bag of electrons, trim to size needed right? =D
04:33 PM Jymmm: `Wolf_: right... https://www.youtube.com/watch?v=tVeNKkQ2HIY
04:33 PM Jymmm: hmmm, this things has six flat packs
04:34 PM `Wolf_: meh 18650, lipos blow up better
04:35 PM `Wolf_: what is said “thing”
04:36 PM `Wolf_: I have rc stuff that runs 3s 2p, 4s 2p, 4s 4p…
04:37 PM Jymmm: `Wolf_: explain the S and p to me please? is that serial parallel?
04:37 PM `Wolf_: yep
04:38 PM `Wolf_: 3 series 2 parallel, 2200mah packs works good for jumping my vw diesel lol
04:38 PM Jymmm: so 3s2p is three in series (7.2v) and teo of those in parellel to double the mAH ?
04:38 PM `Wolf_: 3s would be 11.1-12+
04:38 PM Jymmm: err, yeah,
04:39 PM `Wolf_: 4.2v per cell hot, depeted 3ish, happy 3.7v
04:39 PM CaptHindsight: 8.4
04:40 PM CaptHindsight: Jymmm: the cells 18650 are all standard sizes
04:41 PM CaptHindsight: Jymmm: lithium polymers don't have the standard mechanical specs so you can find them in all sorts of shapes
04:42 PM `Wolf_: and 18650 are li-ion or IMR or other mix
04:42 PM cradek:
04:44 PM `Wolf_: lipoly do bad things when you over discharge them as well, I have a few puffed up packs here
04:45 PM CaptHindsight: mostly due to poor mechanical design
04:45 PM Jymmm: https://i.imgur.com/ej7F8Td.jpg
04:45 PM CaptHindsight: sometimes poor chemistry
04:45 PM Jymmm: six total
04:46 PM `Wolf_: lipoly or li-ion packs…
04:46 PM `Wolf_: they both come in foil pack like that
04:47 PM Jymmm: I dont know, it's actually a well made product and they glued the packs together lol
04:47 PM Jymmm: ...and I cant get to the label =)
04:47 PM `Wolf_: power bank?
04:48 PM Jymmm: Kinda, for 16/19V laptop power pack
04:49 PM Jymmm: you just plug it inbetween the laptop and the wall adapter
04:50 PM ve7it: Jymmm, https://www.ebay.ca/itm/5pcs-3-7V-1200-mAh-Connector-Rechargeable-Polymer-Li-ion-battery-603450-for-GPS/262932456871
04:51 PM `Wolf_: best bet is to measure the cell size and go from there
04:52 PM CaptHindsight: Jymmm: is that the inside of one of those portable batteries?
04:52 PM ve7it: keyword to search for is 603450 that is a physical size 6(H)*34(W)*50(L) mm
04:52 PM CaptHindsight: I used to carry them on long plane trips
04:53 PM Jymmm: CaptHindsight: yes
04:53 PM CaptHindsight: i wonder if mine still work
04:53 PM Jymmm: 57mm x 1200 x 5mm
04:54 PM `Wolf_: you can sort packs on hobbyking by size
05:03 PM CaptHindsight: lets make our own batteries
05:13 PM rmu: https://www.youtube.com/watch?v=WZkqgj1J_WE
05:20 PM Jymmm: `Wolf_: doesnt go up to 1200mm sadly, only 49
