02:09 AM Deejay: moin
02:47 AM XXCoder: nice video! https://www.youtube.com/watch?v=H0Oeg6fhOnQ
03:10 AM gloops: must be satisfying to make an engine and see it running
03:13 AM XXCoder: yeah'
03:13 AM XXCoder: i always wanted a stirling engine
03:17 AM XXCoder: video poctured one isnt one but stirling is one i wanted lol
04:02 AM Rab: https://sanantonio.craigslist.org/tls/d/san-antonio-south-bend-9-model-lathe/6820737840.html
04:02 AM Rab: ...the inside-out link belt...
04:03 AM XXCoder: weirf
04:21 AM jthornton: morning
04:21 AM XXCoder: morning
04:22 AM XXCoder: man its annoying
04:22 AM XXCoder: weather here is so out of wrack that predictions change quite quick
04:23 AM XXCoder: monday was snow all day then now its little bit of sleet at morning then loudy and rain
04:26 AM jthornton: looks like thunderstorms here today then clearing up for a few days
04:26 AM jthornton: I'm tired of the muck
04:27 AM XXCoder: oh look it changed again. cloudy, light rain, then sleet then cloudy again
04:47 AM jthornton: going to try this out on my rpi https://www.pyimagesearch.com/2018/09/26/install-opencv-4-on-your-raspberry-pi/
04:49 AM XXCoder: oh yeah I think theres a way to use raspi as voice to text translator? lemme look up
04:49 AM jthornton: can it translate chicken to text?
04:49 AM XXCoder: lol
04:49 AM XXCoder: would be... interesting
04:51 AM jthornton: the most interesting thing is chickens know the language at birth and know everything how to take care of themselves
04:53 AM XXCoder: i saw that video where chickens stop a cat fight
04:53 AM XXCoder: it sure looked like they was mediating between cats
04:55 AM XXCoder: oh misremembered its rabbits
04:55 AM XXCoder: https://www.youtube.com/watch?v=D35uQCtr4EY
04:56 AM XXCoder: cats hmm oh yeah crows literally picked on cats and started fight
04:58 AM XXCoder: https://www.youtube.com/watch?v=WQd9kuXpUYU
04:59 AM XXCoder: its amazing that crows looks like they are cheering cats on
05:01 AM XXCoder: there was crows research, they found a human mask that crows didnt react to
05:02 AM XXCoder: so masked, one of em annoyed and tried to attack crows bunch of em. crows started attacking
05:02 AM XXCoder: second test was pretty far away from orginial locations. crows come in and attacked guy in mask
05:02 AM XXCoder: crows have memories, and they tell others to watch out.
05:08 AM jthornton: this is a complicated tutorial but well written
05:18 AM jthornton: opencv 4 might be overkill for a chicken camera lol
05:21 AM XXCoder: maybe but eh just need camera and raspi so cost dont increase
05:29 AM jthornton: I found one the other day that was ok but just reading about motion and it might be all I need
05:35 AM jthornton: https://elinux.org/RPi-Cam-Web-Interface
05:35 AM jthornton: that's the one I found the other day
05:35 AM XXCoder: interesting. only supports raspi camera
05:36 AM jthornton: yea that's what I have a raspi camera
05:36 AM jthornton: I do have one usb camera and it is in the egg collection area of the nest box
05:50 AM commavir_ is now known as commavir
06:08 AM XXCoder: https://www.youtube.com/watch?v=0--7CZCVngM nice
06:09 AM XXCoder: i like the idea too
06:10 AM jthornton: I like that foam spoil board
06:11 AM XXCoder: yeah
06:11 AM XXCoder: just keep cutting start fall apert get new one
06:12 AM XXCoder: cheap for that thickness also I bet
06:13 AM XXCoder: was wondering why he added footer bars ah wheels nice but how about tipping risk
06:14 AM jthornton: that's a huge rack
06:15 AM XXCoder: yeah thats why i wondered about tipping
06:17 AM jthornton: I need one of those right angle drivers lol
06:17 AM XXCoder: he has link. $40 dont seem bad for what seems for nice one.
06:19 AM XXCoder: brilliant design really.
06:20 AM XXCoder: angle comes witrh 6 drills and 4 bits
06:20 AM jthornton: I don't like 4 swivel casters on anything, too hard to drive
06:47 AM Tom_L: gives it a mind of it's own..
06:48 AM XXCoder: 4 wheels pointing to back or front = tipping hazard
06:51 AM Loetmichel: yeah, two swivel casters with brakes and two fixed ones without is better
06:55 AM Tom_L: hmm looks like more rain on the way
06:55 AM Tom_L: at least it's not frozen
06:56 AM Tom_L: radar is pretty today. all sorts of greens, yellows reds, pinks, blues...
06:57 AM Tom_L: what a mix.
07:00 AM Tom_L: hmm, blizzard warning just west of here
07:00 AM Tom_L: hope it stays there
07:00 AM Tom_L: predicted gusts to 65mph
07:04 AM jthornton: rain fizzling out here today yea
07:05 AM jthornton: sunny days for a while
07:06 AM jthornton: yippie I got the 7i96 configuration tool to install with pip3
07:07 AM XXCoder: did you ever make linuxcnc_addons or whatever for tools and configurators you made?
07:09 AM jthornton: what do you mean by linuxcnc_addons?
07:09 AM XXCoder: remember I suggested you to make new repo package for people who wants additional utilities
07:09 AM XXCoder: ones you made
07:10 AM XXCoder: ah yes linuxcnc_utils
07:10 AM jthornton: I don't remember that
07:10 AM XXCoder: it was quite a while ago lol
07:10 AM jthornton: https://github.com/jethornton/7i96
07:10 AM XXCoder: dont ask me how my memory work, I dont know. lol
07:11 AM jthornton: I think I tried to add the 7i96 to linuxcnc once but gave up
07:11 AM XXCoder: that might be why we talked about making utility pack
07:12 AM XXCoder: so people who has MESA can add utilities to configure it and other stuff
08:27 AM JT-Shop: anyone want to test my 7i96 configuration tool for me? https://github.com/jethornton/7i96
09:15 AM Tom_itx: for the handfull that may use SW i thought this might be appropriate here: https://my.solidworks.com/training/catalog/list/1?category=f%2Fdb_record_subtype%2FLessons&category=f%2Fdb_record_sublevel%2FGuest&?utm_medium=Email&utm_source=em_indb&utm_campaign=201901_MySW_UpdatedTrainingEmail_Guest&utm_content=_&utm_term=Start-Learning
09:15 AM Tom_itx: training videos
09:24 AM Jymmm: When they run an (earth) ground line from a service panel, is it typically 1/4" flex metalic conduit they use?
09:31 AM jthornton: depends on what the code is at your location or like me there is no code
09:34 AM Tom_L: wrong button
09:35 AM Jymmm: jthornton: no code? or no code for a ground in your area?
09:36 AM Tom_L: i thought they just buried the wire
09:37 AM Tom_L: wouldn't you want a local earth ground anyway?
09:38 AM JT-Shop: no building codes at all
09:38 AM Jymmm: Tom_L: you asking me?
09:38 AM Jymmm: JT-Shop: how strange
09:38 AM Tom_L: you're asking about earth ground
09:39 AM JT-Shop: not really many states don't have state wide code in that case if you live in the city limits you have city code only
09:40 AM JT-Shop: I've never seen a ground wire going to a ground rod inside conduit of any kind... if you have potential of mechanical damage yes
09:40 AM Jymmm: I'm looking for 1/4in version of this https://www.cesco.com/images/products/Electri-Flex/69342.jpg
09:40 AM Jymmm: but I' might be searching the wrong term, can't find on homedepot.com
09:41 AM Tom_L: https://www.graybar.com/store/en/gb/conduit-raceway-and-cable-support/metallic-conduit/steel-flexible-conduit?productBeginIndex=0&orderBy=0&pageView=grid&pageSize=50&pageNumber=1&facetId=
09:42 AM gregcnc: 14-2 is the smallest you're likely to find
09:43 AM Tom_L: https://www.graybar.com/store/en/gb/galvanized-steel-flexible-metal-conduit-93174289#{Trade%20Size%20(Inches):3/8}&{Coil/Reel%20Length%20(Feet):50}
09:43 AM Tom_L: 3/8" is likely the smallest you may find
09:44 AM Jymmm: Would 3/8 OD be 1/4 ID (or there abouts)?
09:44 AM Tom_L: https://www.fastenal.com/products/details/0790332;jsessionid=3MOBC7z2CHzpTPrqmgbocNTS.fcom-s-jeap02:jvm01-fcom-s-jeap02?r=~%7Csattr01:%5E1/4%22$%7C~%20~%7Ccategoryl1:%22601280%20Electrical%22%7C~%20~%7Ccategoryl2:%22601418%20Conduit%20and%20Accessories%22%7C~
09:44 AM Tom_L: there's 1/4 if you want 800'
09:45 AM Tom_L: that designates the inner diameter
09:46 AM Tom_L: Inner Diameter 0.245" - 0.260"
09:47 AM gregcnc: stainless even, fancy
09:48 AM Tom_L: home depot probably doesn't stock it because it would sit on the shelf
09:48 AM Jymmm: gregcnc: Yeah, I noticed that too
09:48 AM Jymmm: Tom_L: ah ok
09:48 AM Tom_L: https://www.homedepot.com/p/AFC-Cable-Systems-3-8-x-50-ft-Flexible-Steel-Conduit-5501-24-AFC/205070918
09:48 AM Tom_L: there's 3/8
09:49 AM gregcnc: what's this for agian?
09:49 AM Tom_L: ground wire
09:49 AM Tom_L: i don't think you need it but i could be wrong
09:49 AM gregcnc: why not use wire as wire? which is why I'm asking
09:49 AM Tom_L: run the bare wire thru it to the access pannel
09:50 AM Tom_L: maybe in industrial but not residential
09:51 AM Tom_L: run a separate green wire and be done
09:51 AM Tom_L: or get 4 cond
09:52 AM Jymmm: Ok, well I've seen that smallerish flex conduit, with no wire in it at all, connected from panel, to ground rod before is all.
09:52 AM Tom_L: in what environment?
09:52 AM Tom_L: that could make a difference
09:52 AM Jymmm: residental (older)
09:54 AM Jymmm: Maybe it is/was to keep a single wire from physical damage (ie cable tv installers etc)
09:54 AM gregcnc: I've seen.... vs, how it should be
09:54 AM gregcnc: people do all sorts of crap, even "electricians"
09:54 AM Tom_L: i think i just ran a separate green wire to my garage but i ran the lot thru conduit since i used plain coated wire
09:55 AM Tom_L: like you would find in a machine enclosure etc
09:55 AM Jymmm: I think conduit was used because it could take more potential abuse than a single wire could.
09:56 AM Jymmm: Kinda like this https://i.stack.imgur.com/HvDA6.jpg
09:56 AM Tom_L: if you're running new, i'd run them all together in one conduit otherwise run a green wire thru your metal jacket
09:57 AM Tom_L: that's because it's exposed
09:57 AM Tom_L: are you running it thru a wall or exposed?
09:58 AM Jymmm: no, it's just something I saw but NO WIRE in the conduit at all
09:58 AM Jymmm: panel straight to grounding rod.
09:58 AM Tom_L: depending on the metal you may need a bi metal paste
09:59 AM Tom_L: remember all the 70's house fires?
09:59 AM Tom_L: due to aluminum wiring
10:00 AM Jymmm: https://www.diychatroom.com/attachments/f18/2589d1203730396-ground-clamps-question-water-line.jpg
10:00 AM Tom_L: that's not a copper wire on that screw on the right?
10:00 AM gregcnc: cheaper than braided copper
10:01 AM Tom_L: otherwise the clamp holding the jacket would be enough
10:01 AM Tom_L: your first pic could have copper inside too
10:02 AM Jymmm: gregcnc: I have soem 1" of that too, but then I'd use copper buss bars for that (RF transmitter)
10:02 AM Jymmm: totally different application there
10:04 AM gregcnc: https://www.nachi.org/bbsystem/viewtopic.php?t=5945
10:06 AM Tom_L: That flexible metal conduit should not be there, it creates all kinds of problems.
10:06 AM Tom_L: I would be interested in hearing some history on flex also, but I think that might be armored covered bare conductor
10:07 AM Tom_L: that's what i thought i saw in your 2nd pic
10:13 AM Tom_L: gregcnc, half those are probably not making electrical connection anyway
10:13 AM Jymmm: Tom_L: you want info /history on the conduit ground or tech details on grounding (I have a tech document on grounds for transmitters which goes way over my head)
10:14 AM Tom_L: no, my grounds are well grounded :)
10:15 AM Tom_L: i'm glad they are grounded though because i was stanind ~20' from a tower when it got hit
10:15 AM Jymmm: heh, ok. Yeah grounds for a 1KW transmitter get... intense
10:16 AM Tom_L: i watched it jump over the insulators on the support wires
10:19 AM Jymmm: Oh this doc goes into lighting supression etc, like I said above my paygrade
10:26 AM gregcnc: https://www.garagejournal.com/forum/showthread.php?t=167353
10:52 AM Jymmm: Well, I really wasn't looking at it for gorunding just wasn't sure of the term used to describe the 3/8 (which I wasn't sire if ID or OD) so I thought it was 1/4"
10:52 AM Jymmm: I'm looking to run a heat strip inside FMC is all, don't now if I need 50ft, though =)
10:52 AM Jymmm: Maybe I'll hit the restore and see what they have
10:53 AM Jymmm: This looks BIG https://www.homedepot.com/p/AFC-Cable-Systems-3-8-x-50-ft-Flexible-Steel-Conduit-5501-24-AFC/205070918
10:54 AM Jymmm: or at least bigger than what I was talking about.
10:54 AM Jymmm: Is this 3/8??? https://www.diychatroom.com/attachments/f18/2589d1203730396-ground-clamps-question-water-line.jpg
11:17 AM gloops: .
11:18 AM gloops: damn! leaking stupid plastic isolation tap on heating, drained it all off, took valve off, sorted the stupid plastic crap out, replaced , filled up
11:18 AM gloops: ive put the stupid valve back back to front
11:21 AM Jymmm: gloops: heating???
11:29 AM gloops: yeah central heating, its ok i just flipped it round live lol
11:32 AM Jymmm: ah
11:37 AM Loetmichel: re at home from work. And tomorrow again a full day (probably more). THIS time its my own fault... Told the customer:" delivery monday in 2 weeks? should work..." now i have to drive 400km to the customer on monday to hold that promise... Here's hoping that i dont botch something tomorrow and really have the two 19" 2u enclosures ready monday morning. :-)
11:40 AM Jymmm: Loetmichel: the dog ate it... DUH
11:41 AM Loetmichel: Jymmm: i doubt the customer would like that ;)
11:44 AM Jymmm: Loetmichel: Was "act of canine" included in their specifications?
11:45 AM Jymmm: Loetmichel: If not, it's their own damn fault, and just upsell em =)
11:46 AM Loetmichel: no, the "specs" was "make it like the last one, just fitting THIS server please" ;)
12:19 PM Jymmm: Loetmichel: Then their fault!!!
04:10 PM Tom_itx is now known as Tom_L
04:26 PM Deejay: gn8
05:35 PM gloops: https://i.pinimg.com/564x/b3/ac/e1/b3ace1493dffc482f155670aec66cce0.jpg?b=t nice chair
05:37 PM XXCoder: perfectly barbarian chair
05:37 PM XXCoder: i hate hosting sites that inject graphics
05:40 PM gloops: well time for bed here anyway
05:58 PM SpeedEvil: XXCoder: extra points if it's sculpted to be comfortable for one person
06:06 PM XXCoder: lol indeed
06:06 PM XXCoder: "if you sit without figeting for 10 hours yiu are the new kjing"
06:06 PM XXCoder: *you *king
06:41 PM MacGalempsy: good evening
07:54 PM XXCoder: "i found solution from site that was actually posted in 1996 I was just 6 months old" Oh... (feels creaky and ancient)
07:58 PM Tom_L: you must have felt the world was gonna end in Y2K then
07:59 PM Tom_L: Jymmm did you know ppl that stockpiled for that?
07:59 PM Tom_L: i knew a couple
08:08 PM XXCoder: tom nah didnt bother to do anything
08:09 PM XXCoder: knew it wouldnt be that big an issue
08:09 PM XXCoder: and it wasnt
08:09 PM XXCoder: now if old unix time rollover happens..
08:09 PM XXCoder: 2048 something I think
08:11 PM Jymmm: Tom_L: I stocked piled... the cash =) I made a buttload of money during the y2k crap in IT =)
08:12 PM Jymmm: Tom_L: But yeah, I knew a few. I did some things, but that was in general, not due to y2k
08:18 PM Tom_L: yeah i bet that would have been a good time to be in IT
08:18 PM XXCoder: 2000 to 2005 or so was great
08:19 PM XXCoder: then .net bubble crashed
08:19 PM Jymmm: The dot bomb
08:19 PM Jymmm: XXCoder: at it was the "dot com", not M$ .net ;)
08:20 PM XXCoder: bah yeah lol
08:20 PM XXCoder: my mind mixed up between those
08:20 PM Jymmm: no worries
08:22 PM Jymmm: Tom_L: Now, Ive just up'ed my game a bit. power, heat, water,
08:24 PM Jymmm: Tom_L: Did you ever look at that generator? gas/propane
08:25 PM Tom_L: which?
08:25 PM Tom_L: mine is on gas
08:25 PM Tom_L: likely will leave it as is at least for now
08:25 PM Jymmm: Tom_L: https://www.amazon.com/XP4850EH-Starting-Electric-Portable-Generator/dp/B00J7V5ENG
08:26 PM Tom_L: cheap enough
08:26 PM Tom_L: shipping might kill it
08:27 PM Jymmm: free shipping
08:27 PM Tom_L: not amazon prime?
08:27 PM Tom_L: did you get one?
08:27 PM Jymmm: nope
08:27 PM Jymmm: No prime, yes I have had it for aout a year, been looking at it for 7 years
08:28 PM Tom_L: why so long?
08:28 PM Jymmm: Wasn't CARB (california epa) approved, it is now
08:28 PM Tom_L: oh
08:29 PM Tom_L: mine's a tiny big bigger than that one
08:29 PM Jymmm: It's quieter than some other gens too.
08:29 PM Tom_L: what engine is it?
08:29 PM Jymmm: some 7hp china thing
08:29 PM Tom_L: huh
08:29 PM Tom_L: no name brand like honda etc
08:29 PM Jymmm: The company is out of Southern California
08:31 PM Tom_L: did you get a twistloc plug for yours?
08:31 PM Tom_L: i made an adapter to plug into my welder outlet in the garage
08:31 PM Jymmm: Tom_L: It came with one actually
08:33 PM Jymmm: Tom_L: The gen came with a L14-30P which was surprising
08:33 PM Jymmm: I just wired it up to cable I already had
08:34 PM Tom_L: not sure what mine is but it looks similar
08:34 PM Tom_L: and i've got a welder extension cord i double up to use for this when needed
10:38 PM Contract_Pilot: Sup all been a while life happens
10:39 PM XXCoder: life happened, is happening heh
