12:18 AM XXCoder: back from couple hours pit fire chat with friend
12:24 AM XXCoder: was fun
12:25 AM veegee: https://www.kijiji.ca/v-view-details.html?adId=1509260629
12:25 AM veegee: 50 HP screw compressor for $750
12:25 AM veegee: just needs a temperature sensor lol
12:25 AM veegee: You ca n't even get the motor for $750. I'm insta buying that shit
12:26 AM XXCoder: lol
12:26 AM XXCoder: sensor is $1000 ;)
12:26 AM veegee: I can bypass that
12:27 AM veegee: or just make a thermocouple circuit
12:27 AM XXCoder: indeed
03:32 AM matic292: Anyone know if its possible or not to install 2.8 on wheezy? ... I have installed Stretch 2.7 now on PC and checked latency .. servo thread 50K+ :s ... I have tested already to install 2.8 on wheezy but no luck... i will use parrarel port and i want designer on it to change some thing to custom but im struggling 3 days in a row now :S
03:34 AM CaptHindsight: yes I have used Stretch a few times last year
03:34 AM CaptHindsight: matic292: id that your latency with RTAI or preempt_RT?
03:34 AM CaptHindsight: id/is
03:35 AM CaptHindsight: servo thread at 50K is good
03:35 AM CaptHindsight: what is your base thread?
03:35 AM CaptHindsight: base thread max jitter?
03:37 AM CaptHindsight: base thread is use for LPT port software stepping
03:38 AM CaptHindsight: matic292: I'll be leaving soon so get you answers and questions in quick
04:11 AM matic292: sorry i was running other machines so i was not here
04:11 AM matic292: CaptHindsight: base thread right now is 207221
04:11 AM matic292: servo thread is 69153 at the momment
04:11 AM matic292: i didnt runned anything in background - like firefox or anything to fill CPU
04:12 AM matic292: this is preemtp_rt i bealive so
04:13 AM matic292: CaptHindsight: when you will have more time? so i will be available that time
04:34 AM CaptHindsight: matic292: does you BIOS let you turn off al power management, speed stepping and virtualization?
04:35 AM CaptHindsight: matic292: id that your latency with RTAI or preempt_RT?
04:36 AM CaptHindsight: matic292: I'll be around in 8+ hours and then again in 18+ fromnow
04:37 AM CaptHindsight: there tend to be more help in here 4-10 hours from now
04:44 AM matic292: Ok i will try to find you here in approx 10 hours
04:45 AM matic292: otherwise i have double checked everything in BIOS. How can i know if it is RTAI or preempt_RT?
06:34 AM Tom_L: morning
06:37 AM JT-Cave: morning
06:40 AM JT-Cave: matic292, uname -a
06:49 AM _unreal_: omg I was tired
06:50 AM _unreal_: woke up felling like I was pressed flat
07:00 AM gloops: lol
10:33 AM * JT-Cave thinks he burned up another rotor on Rusty... wtf
10:35 AM * JavaBean hears jt playing taps
10:38 AM Tom_L: JT-Cave, maybe you need to rebuild the cylinders
10:38 AM Tom_L: calipers
10:40 AM JT-Shop: yea, that's what I'm thinking now...
10:45 AM skunkworks: sticky calipers or a hose that is plugged..
10:47 AM skunkworks: or the float sticking
10:47 AM * skunkworks hates brake work
10:48 AM jymmmm: float?
10:48 AM jymmmm: Cool calculator... https://qalculate.github.io/
10:49 AM jymmmm: skunkworks: vehicle brake work? Metal brake work?
10:51 AM skunkworks: hehicle
10:52 AM Rab_: jymmmm, that's the one I use. It's in Debian, too: apt install qalculate
10:52 AM Rab_ is now known as Rab
10:52 AM jymmmm: Rab: ah ok, thanks
10:53 AM jymmmm: BRB
11:15 AM * jymmmm is back, you were warned ;)
11:26 AM _unreal_: DC brushed servo motor CAP. value is that based on motor specs or an average?
11:31 AM _unreal_: I'm working on getting my motors and encoders connectd right now
12:32 PM JT-Shop: float?
12:33 PM * JT-Shop flushed the brake fluid out after changing rotors and pads
12:35 PM Tom_L: i think he meant if the caliper can slide on it's mount
12:35 PM skunkworks: JT-Shop: the slides the calipers float on.. (if they are that style)
12:36 PM skunkworks: right
12:37 PM Tom_L: he would have discovered that when he changed the pads/rotors i would think
12:38 PM Tom_L: i usually spread them out for the new ones before i take em off
12:39 PM skunkworks: I had a car that slid.. just not far enough for the new pads.
12:40 PM jymmmm: Bottles of brake fluid should be like a IV, hang it upside down, come with a tube, and shutoff valve. Then you'll never emptry the reservoir when bleeding/flushing
12:40 PM Tom_L: i used to go to a brake shop that made their own pad / shoes and once in a while they wouldn't sand them down quite far enough
12:41 PM Tom_L: jymmmm, it's more fun to guess
12:41 PM jymmmm: Tom_L: It's not the geussing, it's the suck air in the lines and have to start all over again
12:41 PM Tom_L: ^^ that's _all_ they did was turn drums, calipers and make pads
12:43 PM skunkworks: Tom_L: are you 90 years old?
12:43 PM Tom_L: hah no
12:44 PM Tom_L: younger than jt
12:44 PM Tom_L: (not by much)
12:45 PM Tom_L: i do remember when disk brakes were a new fad though :D
12:46 PM jymmmm: skunkworks: Hell, Tom_L remembers when horse drawn buggies had brakes
12:46 PM Tom_L: stick against the spoke wheel
12:47 PM jymmmm: lol
12:48 PM Tom_L: wheel bearings were made from hedge wood
12:49 PM jymmmm: Tom_L: and the grease?
12:50 PM Tom_L: can't say. it's a patent secret
12:51 PM _unreal_: is there any certain value for a cap on a brushed servo?
12:51 PM jymmmm: Tom_L: You can tell me, nobody is listening.... chicken grease? coon grease? hog fat?
12:57 PM Loetmichel: *hehe* Teamviewer for the win! Helped my cousin friday after the funeral of my aunt to upgrade his laptop a bit. Installed a new SSD, used the old disk in an external enclosure as backup, and formatted it. Forgot to copy all picture drawers on the desktop though... he just called "where are all the photos?" *ups* 4 hours of undelete scan on the external drive via Teamviewer and all is well
12:57 PM Loetmichel: again. That could have easily be 2 times 3h more because of the drive to my cousin. Thanks TV!
12:58 PM Tom_L: jymmmm, if you really wanna know: https://www.tribstar.com/features/history/historical-treasure-the-conestoga-wagon-grease-bucket/article_c0f7d03b-39e5-54cf-98c1-1c3dd3d6c7f3.html
01:00 PM jymmmm: Tom_L: ok, lard, just like I figured.
01:01 PM rmu|w: _unreal_: if your brushed DC servo requires caps to reduce sparking and EM noise it should have those caps installed from the factory
01:01 PM _unreal_: two of them DO. one does not
01:02 PM _unreal_: the one that doesnt also does not have its original wires and all of my motors are second hand
01:04 PM rmu|w: typically this will be a ceramic cap, exact value is not that important. you could try to desolder and measure an intact one.
01:08 PM Tom_L: i've used 1uf
01:08 PM Tom_L: one to each leg and gnd
01:09 PM Tom_L: rated 2x the motor voltage
01:58 PM veegee: I got a good deal on blowers with integrated motor
01:59 PM veegee: They're rated for 600V which is great, but they're Y wound (I think)
01:59 PM veegee: There's a neutral wire
01:59 PM veegee: What happens if I just connect 600V delta and leave the neutral floating?
02:05 PM rmu|w: 3 phase ac induction motors usually can be wired delta or Y, it's not really a winding thing...
02:05 PM Loetmichel: veegee: IF its 3 phase: nothing: the neutral will be "neutral"
02:05 PM Loetmichel: it will float at appox ground level
02:05 PM veegee: It is 3 phase
02:05 PM Loetmichel: IF your input is real threephase
02:06 PM veegee: and input is real 3 phase
02:06 PM veegee: 600V from the power plant
02:06 PM Loetmichel: and not something from a VFD or Steinmetz-circuit
02:06 PM veegee: VFD is real three phase too
02:06 PM Loetmichel: veegee: but PWM-"chopped"
02:06 PM veegee: I run them at a very high carrier frequency
02:07 PM Loetmichel: gives some funny effects with said neutral/star point
02:07 PM veegee: and I put a line reactor after them
02:07 PM Loetmichel: then the reactor should take care of the "funny things"
02:07 PM veegee: yeah
02:09 PM JT-Shop: skunkworks, the slides all move smoothly
02:09 PM rmu|w: proper VFD should be ok, motor windings act as reactor too.
02:16 PM veegee: Yeah I have a lot of inductance on the output of the VFD
02:18 PM veegee: Also a transformer on the VFD to go from 240V to 600V since I don't have 600V VFDs yet. They're really expensive. I need to get those IGBT modules and make them ASAP
02:25 PM perry_j1987: hows everyone doing
02:27 PM infornography: terrible
02:27 PM infornography: send money
02:30 PM infornography: squirrels in the attic again
02:35 PM perry_j1987: dinner
02:45 PM miss0r: The land rover 101 forward control restoration/camper conversion status photos, in no apparent chronological order: https://imgur.com/a/SmsWyfl :D
02:50 PM jymmmm: miss0r: Are those deep cycle batteries?
02:50 PM miss0r: yeah
02:50 PM jymmmm: miss0r: I hope you are going to insulate them
02:50 PM miss0r: You thinking of the cold weather?
02:51 PM jymmmm: miss0r: OH yeah
02:51 PM miss0r: yeah well.. The idea is that this is a summer RV... If I get other ideas I will do something about it then
02:51 PM miss0r: But these are rated for 77% capacity at -10c
02:51 PM jymmmm: miss0r: Well, too hot is not good either
02:52 PM miss0r: and honnestly, its rare that we even get there now'a'days
02:52 PM miss0r: indeed.
02:53 PM jymmmm: miss0r: HEre's the thing... insulation is a simple passive addition that can CYA. Later never comes, so do it now and be happy you did later =)
02:54 PM miss0r: The thing is; *IF* I insulate it now, I might get issues with the batteries being unable to dissapate the heat generated from charging during a hot summer day
02:54 PM miss0r: and as this RV is being equipped with two 120watt monocrystal solar panels, it is likely to do charging at just that, a hot summer day
02:54 PM jymmmm: and unable to safely charge in the cold. It doens't have to be AIR TIGHT, just enough to keep the bitter chill off
02:55 PM miss0r: :D Well.. yeah. I'm open for insulation ideas. As you can see from the pictures, I've opted for a water proff box, with not alot of free space inside of it.
02:56 PM jymmmm: Yeah, it seems very tight space. Maybe foam board, a moving blanket? And maybe some way to vent in the summer?
02:57 PM miss0r: hmm.. About the vent. The reason I went for a watertight enclosure, is because this RV is going to be driven into mud/water/other stuff :D
02:58 PM jymmmm: miss0r: Is that box below the floorboard?
02:59 PM miss0r: yeah
02:59 PM jymmmm: Well, maybe the mud/water will cool it?
03:00 PM miss0r: hehe yeah
03:00 PM miss0r: it is mounted right underneath the "double door" in the side of it: https://imgur.com/a/QJTesXX
03:00 PM jymmmm: or the dried mud will make any heating issues worse
03:01 PM miss0r: hmm.. well, Dried mud *should not* become an issue, as I am very thorough about washing that stuff off in a hurry
03:02 PM jymmmm: miss0r: And I menat thermal venting, not so much water venting
03:03 PM miss0r: yeah, I got the idea of where you were going
03:03 PM jymmmm: initially I was thinking air cooled, thus venting.
03:03 PM jymmmm: miss0r: Now, there is one trick you could do though
03:03 PM miss0r: At the moment I have one rubber hose connected to the top of the box, that runs the wires up to a "safe height"
03:03 PM miss0r: I guess I could add another in the other end of the box and force some air through
03:04 PM jymmmm: miss0r: A single loop of 1/4" copper tubing
03:04 PM jymmmm: miss0r: tap into the radiator system in the winter to keep the battery warm, and no clue in summer, maybe run through a lot of rivers :D
03:04 PM miss0r: haha yeah
03:05 PM miss0r: Nice idea with the coolant loop
03:05 PM miss0r: I'm just worried about making this overly complicated. If theres one thing that kills cars it is that
03:05 PM jymmmm: a tiny valve could just keep things above freezing temps, not sure about condensation though
03:06 PM miss0r: At the moment the complete assembly can be removed with two quick connects(for the up comming water and sewage resevoirs & one multi connector plug for the batteries & pumps)
03:06 PM miss0r: Then you can remove the entire assembly with two M10 bolts and two hinge tabs
03:07 PM jymmmm: I just know close to freezing temps kills batteries is all
03:07 PM jymmmm: Maybe you can toss in an electric heater in there, a coil of nichrome wire, whatever
03:07 PM miss0r: Indeed. but leep in mind these are AGM, alot less receptive to death by freezing than 'yer regular lead acid batteries
03:08 PM miss0r: Yeah, Heating mats for batteries are exactly what I need!
03:08 PM jymmmm: True, but charging in cold temp is a bitch
03:08 PM miss0r: do those come in cooling as well? :D summer is my main concern as it is
03:08 PM miss0r: (I know they don't)
03:09 PM jymmmm: Yeah, one of those electic coolers, hot and cold
03:09 PM miss0r: I should add an air condition just to keep the batteries happy. which will also take up all the power they store, rendering it useless :P
03:09 PM jymmmm: solar ?
03:09 PM miss0r: yeah
03:10 PM jymmmm: so you are putting on solar panels?
03:10 PM miss0r: yeah. two 120 watt monocrystal panels
03:10 PM jymmmm: do oyu already have the panels?
03:10 PM miss0r: running it through a MPPT charger.
03:10 PM miss0r: yeah
03:10 PM jymmmm: which mppt?
03:11 PM miss0r: This one: https://www.vivaenergi.dk/solcelle-webshop/mpp-tracker/laderegulator-2040-lithium-40a
03:11 PM miss0r: It came highly recommended by a guy I know
03:14 PM jymmmm: Ok, so it's both lead and LiFe, nice
03:14 PM miss0r: I just need to mod this particular unit to move the temperature sensor that is somewhat build in, to entend it to the batteries
03:14 PM miss0r: yeah
03:14 PM miss0r: entend=extend
03:15 PM jymmmm: miss0r: Ok, if you ever do change out to LiFe, you can NOT ever charge them in cold temps, ever.
03:15 PM miss0r: what makes you say that?
03:17 PM miss0r: These are the solar arrays, btw: https://www.vivaenergi.dk/solcelle-webshop/flexpaneler/2018-120w-flexpanel-12v
03:17 PM jymmmm: miss0r: It damages them. a GOOD BMS will have a Low Temp Disconnect. YOu cna draw from them, but NOEVER charge during low temps
03:17 PM miss0r: Alright. :)
03:18 PM miss0r: well. Good thing is; in cold weather I won't have the use for a large battery capacity, as this is mainly for running the fridge.
03:18 PM miss0r: the 4 3watt LEDs in the loft of the RV can run forever while not charging :)
03:19 PM jymmmm: miss0r: Does that SCC (Solar Charge Controller) have a "dusk to dawn" feature?
03:19 PM miss0r: ahh... What is that, exactly? :D
03:20 PM jymmmm: miss0r: Ok, where do you have your LOAD connected to? the battery directly, or thru the SCC?
03:20 PM miss0r: both actualy.
03:21 PM miss0r: I will be connecting an inverter directly to the batteries, as it can draw more than the 40 amps I am allowed to draw through the charger
03:21 PM miss0r: I do not, however, plan to ever have it draw that ammount, but better safe than sorry
03:22 PM jymmmm: miss0r: Ok, read the SCC manual, the "LOAD" terminals, you might be able to program it to run things only from "dusk to dawn"
03:22 PM miss0r: all the other usage will go through the charge controller, set to not allow discharging the batteries below 50%
03:23 PM miss0r: so... to shut off me using power when the sun is down? :)
03:24 PM jymmmm: no, to operate things only during dusk to dawn, like a nightlight
03:27 PM jymmmm: miss0r: one idea... https://www.amazon.com/Facon-Holding-Trailer-Automatic-Thermostat/dp/B01MT9EUG9/
03:27 PM miss0r: Yeah
03:28 PM miss0r: Anyway. I will pick up on this conversation at another time. I have to catch some shuteye (early client comorrow)
03:28 PM miss0r: See you around
03:28 PM jymmmm: miss0r: Cold Temperature Protection Heat Pad: 12 volt thermostatically controlled black water tank heater pad. This will automatically heat up the battery if the battery gets too cold (I do not have one on mine because I live in san diego). This heat pad will turn on at 45 degrees F, and shut off at 68 degrees F, so to ensure that this heater pad does not waste any power, be sure to insulate the battery compartment and area arou
03:28 PM jymmmm: nd the battery. If it is insulated nicely, this pad will work well. If the battery is next to a lot of metal, such as an outdoor battery compartment that is vented, you will need to find another type of heater pad that turns on at a lower temperature. 
03:28 PM jymmmm: miss0r: laters
03:30 PM jymmmm: miss0r: Lot of great info... https://www.mobile-solarpower.com/diy-lifepo4-solar-battery.html
03:30 PM jymmmm: primarily LiFe, not AGM
03:31 PM SpeedEvil: Insulation is a problem - batteries can get warm/hot when charging or diccharging
03:31 PM jymmmm: SpeedEvil: Yeah, in an enclosed space, seems both heating and cooling are needed

03:48 PM perry_j1987: who broke the irc lol
03:49 PM jymmmm: JT-Cave: must be taking a nap in the rocking chair and pulled the cat5 cable
04:04 PM skunkworks: just spend an hour seting up a lathe tool table.. Only took 3 tries.
04:04 PM * skunkworks doesn't do lathes very much.
04:04 PM veegee: So goodyear makes 2" rubber air hoses: https://www.goodyearrubberproducts.com/files/GoodyearIndustrialHose/GoodyearIndustrialHoseCatalog/GoodyearIndustrialHoseCatalog1.Page029gpage.asp
04:05 PM Tom_L: first time i tried my cad cam on a lathe i had them backwards too
04:05 PM veegee: I wonder how the cost compares to black pipe
04:05 PM Tom_L: still wandering what to do ehh?
04:06 PM Tom_L: skunkworks, also set up my corner rounding cutters i'll be getting tomorrow
04:06 PM veegee: Still deciding on what to use
04:07 PM veegee: Also there's the rapidair aluminum stuff
04:07 PM Tom_L: black pipe would probably be cheapest
04:07 PM veegee: Have to figure out the cost of all this. Black pipe is highly appealing for its availability, cost, etc.
04:07 PM Tom_L: rapidair easiest to install likely
04:07 PM Tom_L: copper is prettier
04:07 PM veegee: Don't care about installation ease
04:07 PM veegee: Or prettiness
04:07 PM Tom_L: heh
04:08 PM Tom_L: i used black pipe on mine
04:08 PM veegee: Copper is corrosion resistant and I'd love to get it but it is indeed extremely expensive
04:08 PM Tom_L: 25+ yrs back and it's still goin strong
04:08 PM veegee: Do you have an air dryer?
04:08 PM Tom_L: no
04:08 PM Tom_L: i used to have a small drier at the end but not now
04:08 PM veegee: Ok cool good enough for me. Black pipe it is. Heading to home depot now :D
04:08 PM Tom_L: but
04:08 PM veegee: I'm thinking 1.5"
04:09 PM Tom_L: black pipe 25yrs ago was higher quality than the chinese almost black pipe you get today
04:09 PM veegee: I have an air dryer. Will put a desiccant dryer in series after the refrigerated air dryer
04:09 PM veegee: That should make corrosion a non issue
04:10 PM veegee: Yeah it's all Chinese steel now but that's ok, I'm not relying on it for its yield strength
04:10 PM veegee: They can all handle the small max 300 psi that I'll be running
04:10 PM Tom_L: mine is 175psi to the reg on the end too
04:10 PM veegee: yeah high pressure is the way to go
04:11 PM Tom_L: my bud ran a tankless screw compressor in his shop
04:11 PM veegee: Not a fan of screw compressors
04:11 PM Tom_L: it was loud but it worked fine
04:11 PM veegee: low pressure, delicate, high maintenance
04:11 PM Tom_L: he put it in a room by itself
04:12 PM veegee: My piston pumps are beautiful. They make a nice low RPM pumping sound
04:12 PM veegee: like a fat V twin, but MUCH quieter
04:12 PM veegee: it's quite pleasing actually
04:12 PM veegee: And there's something about big, solid, heavy cast iron machines
04:12 PM Tom_L: mine is a 2 stage as well
04:13 PM veegee: They have this timeless presence like a classic car, or a 1960s Cincinnati mill
04:16 PM veegee: What a beautiful machine: https://i.redd.it/00rtgf8rutc21.jpg
04:16 PM veegee: I LOVE the art deco style

04:17 PM Tom_L: you should have seen the 5 axis cincinnati here at mpm
04:19 PM Tom_L: https://www.youtube.com/watch?v=mxxdq6y8z8M
04:19 PM veegee: Very nice!
04:19 PM veegee: Can afford 5 axis mill
04:19 PM veegee: But only 240p camera
04:19 PM Tom_L: i have no room for that monster either
04:20 PM veegee: Plenty of room in my shop. I really have to turn this into some kind of business
04:21 PM jdh: gambling and 'entertainment' in the back?
04:31 PM jymmmm: Tom_L: But it dont make chips or salsa or anything
04:42 PM Tom_L: it makes chips
05:40 PM _unreal_: getting close. tonight I'm going to do a TEST power up with the motors plugged in
05:41 PM _unreal_: 7i96 What pin should I connect to use for killing the motor control relay?
05:41 PM _unreal_: killing the motors
05:49 PM _unreal_: interesting so I just popped my 12A fuse
05:49 PM _unreal_: in my PSU
05:49 PM _unreal_: dont know why
05:50 PM _unreal_: looks like I'm going to have to unplug motors and toss a new fuse lower fuse in and test again
06:02 PM * JavaBean watches a ProjectFarm youtube video, idly wonders if JT in his various forms watches as well
06:02 PM gregcnc: why do you watch him? just curious
06:03 PM JavaBean: product reviews... but this video was about running his farm
06:03 PM jymmmm: gregcnc: HE gives some brutal REAL TEST reviews
06:03 PM gregcnc: a few have been OK. most are marginal at best
06:04 PM JavaBean: real test?? dude defines the term "stress test"
06:04 PM jymmmm: gregcnc: marginal, how so?
06:05 PM jymmmm: gregcnc: He talks too fast sometimes, but that's about it
06:06 PM gregcnc: they appear knowledgeable on the surface. i'ts cool that he manages to make money doing what he does, but I've never learned anything expected the rust preventative tests he did, then again the other days comment about a sinle chart being able to give all the results the video gives
06:07 PM jymmmm: gregcnc: But the chart wouldn't have shown the fuses NOT blowing when they should have.
06:07 PM gregcnc: sure why not
06:08 PM jymmmm: gregcnc: how would you put that in?
06:08 PM jymmmm: miss0r: You need USB ports on your dash, not just 12V sockets =)
06:09 PM gregcnc: is the fuse rating that hard to read on a plot of voltage and current?
06:09 PM jymmmm: gregcnc: The fuse was rated fine, it just didn't blow when it should have in one test, but did in another
06:10 PM gregcnc: fuses are tricky
06:16 PM gregcnc: did you sort your generator?
06:19 PM jymmmm: gregcnc: No. I want to double check that I haven't been overfilling it to be 100% sure, just in case. But I have to drain it, measure how much came out, measure how much I'm going to fill it with (calls for 20oz), etc
06:21 PM gregcnc: ah OK.
06:22 PM Tom_L: by weight or volume?
06:23 PM * Tom_L gives jymmmm a 20 oz hammer for comparison
06:25 PM skunkworks: I use the dip stick.. I know - right?
06:25 PM gregcnc: I only weigh grease for bearings
06:28 PM Tom_L: speaking of dip sticks...
06:28 PM skunkworks: heh
06:28 PM Tom_L: back when motor oil came in quart cans i would check the dipstick and fill to the line
06:29 PM Tom_L: now that it comes in 5 qt pails i just dump it all in and go
06:29 PM Tom_L: dip sticks are obsolete!
06:29 PM jdh: why didn't you just dump in 5 quarts
06:29 PM gregcnc: some cars don't have them anymore
06:29 PM Tom_L: who want's to store an almost empty 5 qt pail anyway?
06:30 PM Tom_L: jdh, because the dipstick was more important back then?
06:30 PM gregcnc: my cars take odd amounts I have at least two partials at all times.
06:32 PM Tom_L: ok here's a test..
06:32 PM Tom_L: anybody (besides JT) remember cardboard quart oil cans?
06:34 PM gregcnc: I saw some, two stroke oil even. right beside a 1977 artcic cat panther on a farm my uncle bought in the 90's
06:34 PM Tom_L: https://www.ebay.com/c/1400985725
06:34 PM pcw_home: I do, plus the spouts you used with them
06:35 PM Tom_L: pcw_home, i may still have the spout :)
06:36 PM pcw_home: I think the last one I saw was in my moms house when we sold it
06:37 PM pcw_home: (~20 years ago)

06:38 PM gregcnc: i was born in 1977
06:38 PM Tom_L: i can only wish that
06:40 PM Tom_L: from that they went to round plastic, then rectangular quart and now what we have today
06:40 PM Tom_L: i kept a round plastic one and use it for a funnel now
06:40 PM jdh: I wrapped the spout in the towels by the windshield cleaners and wedged in by the battery
06:41 PM jdh: the first round ones always dripped over the valve covers when you tried to pour them
06:41 PM pcw_home: When I was a kid my father brought home a bunch of the cardboard tubes used for the cans (about 5 feet long with continuous spiral labels)
06:43 PM pcw_home: we had a lot of fun with them as drums (some would telescope so you had a tunable drum)
06:52 PM skunkworks: 1973
07:08 PM jymmmm: skunkworks: The specs call for 20oz, but I'm not sure if it's draining 20oz too
07:09 PM jymmmm: or if oil is being consumed, etc
07:54 PM pink_vampire: what do you think about this dial test indicator? https://www.ebay.com/itm/264347863377
07:56 PM Tom_L: it's not pink.
07:56 PM Tom_L: mitutoyo is a good brand
07:56 PM skunkworks: For some reason - I never used the wiggle style indicators...
07:57 PM Tom_L: they're handy for some things over a normal dial
07:57 PM skunkworks: I am sure.. There are some situations that I should have used one...
07:57 PM pink_vampire: https://www.ebay.com/itm/362964229452
07:57 PM Tom_L: wait.. that doesn't say mitutoyo does it>
07:57 PM Tom_L: ?
07:57 PM pink_vampire: how is this one?
07:58 PM serp: It says Mihohogu
07:58 PM skunkworks: close.. ;)
07:58 PM Tom_L: it's still not pink
07:58 PM Tom_L: don't buy it
07:58 PM skunkworks: it is through my rose colored glasses..
07:58 PM jymmmm: pink_vampire: Yep, don't buy it, it's not pink!
07:58 PM Tom_L: haha
07:59 PM jymmmm: skunkworks: rose aint pink either
07:59 PM Tom_L: depends how much red wine you've had
07:59 PM SpeedEvil: Except for pink roses
07:59 PM pink_vampire: my dial indicator is dead
07:59 PM pink_vampire: I need new one
07:59 PM SpeedEvil: dead how?
07:59 PM jymmmm: pink_vampire: QUICK paint it pink, it'll work good as new
08:00 PM * skunkworks is color blind anyway..
08:00 PM Tom_L: i got a cheap one in a kit with one of those fake noga arms and i use it for "every day" and keep the mitutoyo for special occasions
08:01 PM pink_vampire: it is worked fine, but it is not very sensitive as I liked since the gravity test
08:01 PM Tom_L: i'm sure the dial will spin and tell you something...
08:03 PM Tom_L: i found on the cheap ones the dial doesn't turn smooth when you zero it
08:03 PM pink_vampire: I need it almost exclusively to dial stuff on the 4 jaw on the lathe, and to trim the vise.
08:04 PM jymmmm: pink_vampire: and the lathe and vise are pink, right?
08:04 PM pink_vampire: no,
08:04 PM pink_vampire: blue lathe, black vise
08:04 PM pink_vampire: https://www.ebay.com/itm/182691752456
08:04 PM jymmmm: pink_vampire: Well, shit, there's your problem
08:05 PM pink_vampire: this is look decent
08:06 PM pink_vampire: also more then 700 people got it..

08:10 PM Tom_L: get a used one?
08:10 PM jdh: you don't need accuracy for dialing in a 4-jaw
08:11 PM Tom_L: no holders though
08:11 PM pink_vampire: used dial is not a very good idea
08:11 PM jdh: sell yours to offset the cost!
08:11 PM Tom_L: heh
08:12 PM pink_vampire: I thinking to get the igaging
08:13 PM Tom_L: then why did you ask?
08:14 PM jdh: do they make a dti?
08:15 PM pink_vampire: https://www.ebay.com/itm/182691752456
08:15 PM pink_vampire: yes, ^
08:15 PM pink_vampire: jdh: ^
08:16 PM pink_vampire: why all the metric dials are yellow!!?!?!?!!?!
08:16 PM * jymmmm lmao @ pink_vampire
08:16 PM Tom_L: so you can tell the difference
08:16 PM pink_vampire: I know how to read
08:16 PM jdh: I have yellow starrets at work. with real units
08:16 PM Tom_L: just a w a g
08:17 PM Tom_L: yeah i know
08:17 PM Tom_L: personal preference probably
08:17 PM MrHindsight is now known as CaptHindsight
08:17 PM Tom_L: maybe some see yellow better
08:17 PM CaptHindsight: <-- still looking for used Delta Robots
08:19 PM CaptHindsight: one of favorite oil can clips https://www.youtube.com/watch?v=Tcwz8-EfFYE
08:19 PM pink_vampire: CaptHindsight: folding landrary
08:24 PM pink_vampire: what do you think about metric dial vs inch?
08:25 PM Tom_L: nothing. i use inch
08:25 PM pink_vampire: I'm trying to switch to metric.
08:26 PM Tom_L: yeah they tried that in the 70's
08:26 PM pink_vampire: the mill is metric the lathe is imperial, and most of my good taps are metric
08:27 PM pink_vampire: and I'm doing cad on metric
08:27 PM Tom_L: get one of each
08:30 PM pink_vampire: there is no point, I'm not running a production
08:30 PM Tom_L: it doesn't matter what i think then
08:31 PM jdh: you don't need units for dialing a 4-jaw
08:31 PM jdh: or tramming
08:34 PM _unreal_: ve7it, this is driving me fucking crazy I cant find the PSU to the laptop with a serial port on it
08:34 PM _unreal_: I have an old p1 laptop, I've had old dos games on for ever. I have not used it in 5 months and now I've totally lost the PSU
08:36 PM pink_vampire: _unreal_: updatedb && locate PSU
08:36 PM _unreal_: its not even funny level the PSU should be with it in its laptop bag and its gone
08:36 PM _unreal_: I dont even know where to look
08:36 PM _unreal_: been tearing the room apart all day
08:53 PM pink_vampire: mmm
09:08 PM gregcnc: pink_vampire I don't think they made indicators like this though. https://www.greatgages.com/products/505-675-52-mitutoyo-dial-caliper
09:10 PM pink_vampire: this is SOOOOOOOOOOOO CUTE!!!!!!!!
09:11 PM pink_vampire: gregcnc: <3
09:12 PM gregcnc: these have been around for a while all sorts of colors, not sure they still make them
09:20 PM CaptHindsight: crazy colors tell them apart from others similar models in the same shop
09:20 PM CaptHindsight: and some still prefer an analog gauge
09:20 PM CaptHindsight: they got used to them years ago
09:33 PM acer is now known as _unreal_
09:33 PM _unreal_: hello
09:33 PM _unreal_: ok now I'm on using my lcnc system
09:33 PM _unreal_: ve7it, was talking about terminl connecting to the motor contoller via serial
09:34 PM _unreal_: trying to figure out how to
09:35 PM CaptHindsight: serial port <-----> serial port
09:36 PM _unreal_: I have that much done
09:36 PM _unreal_: I found a USB to serial adapter so I have that setup right now but I dont know if the drivers are loaded
09:36 PM _unreal_: LS is not installed for some reason so I cant see the usb device list lsusb
09:37 PM _unreal_: how do I install LS ?
09:37 PM CaptHindsight: what version of debian?
09:37 PM _unreal_: Linux lcnc 4.9.0-8-rt-amd64 #1 SMP PREEMPT RT Debian 4.9.110-3+deb9u6 (2018-10-08) x86_64 GNU/Linux
09:38 PM CaptHindsight: that is the kernel
09:38 PM _unreal_: I forget the command then to get that info
09:39 PM CaptHindsight: likely: apt-get install usbutils
09:40 PM _unreal_: already instaled
09:40 PM CaptHindsight: might as well grab pciutils at the same time
09:40 PM CaptHindsight: what happens when you type lsusb at the command line?
09:41 PM _unreal_: wtf?
09:41 PM _unreal_: before it was giving me badcommand or file name
09:41 PM _unreal_: now its giving me lsusb responce
09:41 PM CaptHindsight: typo maybe
09:42 PM _unreal_: ? nope
09:43 PM CaptHindsight: NSA scanning your computer for threats
09:43 PM _unreal_: could be
09:43 PM _unreal_: is there a pastebin pre setup?
09:44 PM _unreal_: I'm rather sure this is my serial adapter
09:44 PM _unreal_: Bus 001 Device 003: ID 050d:0109 Belkin Components F5U109/F5U409 PDA Adapter
09:44 PM _unreal_: yep thats it
09:44 PM _unreal_: now how to figure out its com port and how to work minicom
09:50 PM _unreal_: ?
09:52 PM Rab: I always hated minicom...these days I use screen in console, or CuteCom in GUI.
09:53 PM _unreal_: I'm trying to connect to ve7it servo motor controller serial term connec tion to the pic
09:53 PM _unreal_: and I've lost my fucking power supply to the only computer I still own that has a real serial port on it
09:53 PM _unreal_: I'm dumb founded becuase it was not in the laptop bag....
09:54 PM _unreal_: just got
09:54 PM _unreal_: gone
09:54 PM Rab: Where did you last use it? Maybe it's still plugged into the wall.
09:56 PM _unreal_: months ago
09:56 PM _unreal_: I lable all of my PSU's
09:56 PM _unreal_: it should be in the bag if its not in the bad I got NO fucking clue
09:56 PM Tom_L: neither do we
09:57 PM _unreal_: so as I said I have a usb to serial adapter that I've plugged into my lcnc machine
09:57 PM _unreal_: trying to figure out what the com port is and how to use it to terminal into ve7it motor controller
10:06 PM _unreal_: any ideas on how I go about getting access this this serial prot?
10:07 PM Tom_L: did you run lsusb?

10:11 PM CaptHindsight: https://www.usb-drivers.org/usb-serial-port-adapter-rs-232-in-ubuntu-linux.html
10:11 PM Rab: Chances are excellent that if your kernel recognized it, it's at /dev/ttyUSB0 or /dev/ttyACM0.
10:11 PM _unreal_: linuxcnc@lcnc:~$ dmesg | grep tty
10:11 PM _unreal_: [ 0.000000] console [tty0] enabled
10:11 PM _unreal_: [ 10.948386] usb 1-5: MCT U232 converter now attached to ttyUSB0
10:11 PM _unreal_: so tty0
10:12 PM Rab: ttyUSB0.
10:14 PM Rab: _unreal_, sudo apt install cutecom && cutecom
10:16 PM _unreal_: installing
10:16 PM Rab: Then select /dev/ttyUSB0, and adjust the baud rate to whatever you need under Settings.
10:16 PM _unreal_: the only option
10:16 PM Rab: And hit Open.
10:16 PM Rab: You can short pins 2 and 3 on the USB serial adapter to make a loopback connection and see if it's working.
10:21 PM _unreal_: loop back works
10:21 PM _unreal_: not getting any responce from the controlle
10:21 PM _unreal_: trying swapping wires
10:23 PM CaptHindsight: device01 output ----> device02 input, device01 input <--- device02 output

10:30 PM veegee: Ok so this guy I bought a refrigerated air dryer from (nice guy) really hates black pipe
10:30 PM veegee: He keeps saying go with galvanized
10:31 PM veegee: He's offering a pretty big discount if I get the pipe from him over something like home depot
10:31 PM veegee: Which I totally don't mind, but I brought up the issue of zinc flakes coming off and damaging tools or being dangerous projectiles out of an air blow gun
10:32 PM veegee: And he said that applies to rust flakes too. I mean I guess that's true
10:32 PM veegee: But the point of the air dryer is to remove a significant amount of water from the air and make rust a non issue right?
10:34 PM _unreal_: oh I got a responce finally
10:34 PM _unreal_: wierd
10:35 PM _unreal_: veegee, air dryers do a good job but dont get 100%
10:35 PM _unreal_: projectials HELL YA but if you use an air filter you dont have to wory
10:35 PM veegee: Well yeah of course, they can only go so low
10:35 PM _unreal_: as much
10:36 PM veegee: Yeah I'll have filters for sure
10:36 PM _unreal_: then you dont have much to worry about
10:36 PM Tom_L: don't aim it at your eyes
10:36 PM _unreal_: I prefer aluminum air plumging my self
10:36 PM veegee: I'll be using the blow gun to blow myself off (don't take that out of context)
10:36 PM _unreal_: !! :( dman it
10:36 PM _unreal_: damn
10:36 PM veegee: So I'll need a good filter or at least make a custom filter
10:36 PM Tom_L: veegee, that's against company policy at my kids work
10:37 PM Tom_L: not allowed to use air on their person
10:37 PM _unreal_: just get a standard air filter
10:37 PM _unreal_: in line air filter
10:37 PM _unreal_: ve7it, I got a responce from one of the pics finally
10:37 PM veegee: Tom_L yeah but it's so effective
10:37 PM veegee: and it cools you down too
10:37 PM _unreal_: just giving me hex code but at least its resonding
10:37 PM veegee: and if it's dry, it'll evaporate the sweat on your body
10:37 PM veegee: it's soooo nice
10:38 PM veegee: I'll never not blow myself off
10:38 PM _unreal_: I use air like that as a hand dryer
10:38 PM _unreal_: much faster
10:38 PM Tom_L: isn't that what you bought 10k air conditioners for?
10:38 PM veegee: 10 ton
10:38 PM veegee: less than $2000 in price
10:38 PM veegee: But yes
10:39 PM veegee: They're still highly effective for removing debris off your clothes and from your hair
10:39 PM veegee: rapidair uses aluminum but seems a bit expensive
10:40 PM veegee: Galvanized is pretty much the same price as black pipe and I can get nice fat large diameter pipe
10:40 PM Tom_L: if you're using high pressure and regulating it at the endpoint why do you need large diameter?
10:41 PM veegee: I like to overkill
10:41 PM veegee: just for the hell of it
10:41 PM veegee: #YOLO
10:44 PM veegee: But yeah I d on't plan to go crazy. 1.5" is fine with me.
10:45 PM Tom_L: go with 6" and you won't need another tank
10:45 PM veegee: I'm going to get huge air tanks to store the dried air
10:45 PM veegee: Like 240 gallon tanks
10:46 PM veegee: I'd prefer the pumps to run longer with fewer start/stop cycles
10:46 PM veegee: I added an oil pump and automotive oil filter to it as well. Definitely makes a difference to the colour of the oil.
10:58 PM _unreal_: ve7it, I'm only getting output like this "[23:48:45:506] <0xbf><0xfc><0xff><0xb0>n<0xc3><0xc3>{"
11:03 PM _unreal_: well I give up for now
11:03 PM _unreal_: no idea what to do
11:13 PM ve7it: _unreal
11:18 PM veegee: Any off the shelf power usage meters for 240V/600V 3ø?
11:18 PM veegee: Something similar to a kill-a-watt
11:19 PM veegee: So I can measure power usage, power factor, etc. in real time
11:27 PM JavaBean: try "hopi" i think... bigclive uses something that sounds like that in most of his vidia's
11:38 PM JavaBean: yeah, its "Hopi". thats the one that bigclivedotcom uses
