04:25 AM onceloved: 666
04:28 AM XXCoder: ?
04:29 AM travis_farmer[m4: no idea what the relevance is there...
04:29 AM liaoque: be off duty
04:36 AM Tom_L: morning
04:37 AM author[m]: evening
04:38 AM author[m]: a pleasant weekend is about to begin
05:23 AM JT-Cave1: morning
05:42 AM JT-Cave1: rooster just crowed
06:23 AM travis_farmer[m4: 66F with a high of 78F and 95% humidity... last night we got tons of rain. washed out several roads and bridges with flash floods.
06:23 AM pere: Very happy to see the number of translators raising on <URL: https://hosted.weblate.org/engage/linuxcnc/ > :)
06:29 AM * travis_farmer[m4 heads out to shop before the heat sets in...

07:15 AM * travis_farmer[m4 is back in from shop... was just testing the "mqtt-publisher.py" component on my setup... it seems very slow to publish
08:44 AM roycroft: today is my last day of work before my vacation
08:45 AM XXCoder: oh can you work on this case tomorrow?
08:45 AM roycroft: tomorrow starts my crazy insane busy time
08:52 AM Tom_L: 6.4 still building
09:01 AM Tom_L: roycroft, what are you coating that plank with since it's gonna be exposed to the weather?
09:06 AM roycroft: i was planning on tried & true varnish oil, but since it's so close to when i need to install it i might need to use a different finish that cures faster
09:07 AM roycroft: it shouldn't really be exposed to the weather much, if at all - i'll install it on sunday, and it will be removed a week later and stored indoors until next year
09:07 AM Tom_L: oh
09:07 AM Tom_L: i thought it was a permanent fixture
09:07 AM roycroft: if it were going to be in the weather year-round i'd probably use epoxy
09:08 AM roycroft: no, we can't have any horizontal surfaces permanently installed
09:08 AM roycroft: for one thing, this is going on a counter that's at ground level next to a river, and it floods every year
09:08 AM roycroft: second, we let nature reclaim the fair after our event, and we want sunlight and rain to be able to get to the ground
09:10 AM roycroft: https://roycroft.us/Booth44-Pre-Fair.jpeg
09:10 AM Tom_L: i've seen that i think
09:10 AM roycroft: i have to pack everything we leave behind into the loft, and it has to all fit in a 2' deep area
09:10 AM roycroft: anything else needs to be removed from site
09:10 AM roycroft: so the loft sides and deck are all stacked up vertially in the front of the loft
09:11 AM roycroft: in that pic, the skeleton of the main counter is on the ground, screwed to one of the posts
09:12 AM roycroft: but i store that in the loft as well now, because it usually ends up floating down the path and i have to find it every spring
09:12 AM Tom_L: on the left side
09:12 AM roycroft: yes
09:12 AM roycroft: and on the right side is where i screw the counter top to the posts
09:12 AM roycroft: below the diagonal brace
09:13 AM roycroft: the flood water gets up to the bottom of the counter top
09:13 AM Tom_L: 3-4'
09:13 AM roycroft: yes
09:14 AM roycroft: https://roycroft.us/Booth44.jpeg
09:14 AM roycroft: that's what it looks like when it's set up
09:15 AM roycroft: the new counter i'm building will go over on the left, where the table covered with the red fabric is
09:15 AM Tom_L: we have a farmer's market here on weekends that has similar goods
09:15 AM Tom_L: but it's in a parking lot type space
09:16 AM roycroft: every tree in that picture is going to die
09:16 AM roycroft: since we're so close to the river, almost all the trees in our part of the fair are ash trees
09:16 AM Tom_L: https://sp-ao.shortpixel.ai/client/to_auto,q_lossy,ret_img,w_655/https://wichitaonthecheap.com/wp-content/uploads/farmers-market-at-sedgwick-county-extension.jpg

09:18 AM roycroft: nice
09:19 AM JT-Shop: looks like summer has a grip on us now... won't see <70°F for a while now
09:19 AM roycroft: that's kind of like our saturday market
09:19 AM JT-Shop: chickens get ice water...
09:19 AM Tom_L: there's a couple locations here
09:19 AM Tom_L: the county extension office has their own
09:20 AM * Tom_L forgot how long it takes to build a kernel
09:20 AM roycroft: https://www.eugenesaturdaymarket.org/
09:21 AM roycroft: our saturday market is one of the first ones in the country, and holds the trademark "saturday market"
09:21 AM roycroft: it started around the same time as the country fair started, and by some of the same people
09:22 AM roycroft: and interestingly, the country fair's current executive director, who is from alaska and has no long history with either event, was the director of saturday market right before she came to work for us
09:26 AM mrec: does anyone know if a stepper motor is controlled via full steps turning off the driver and turning it on again will keep it at the same position?
09:27 AM mrec: That's something I haven't tried yet, normally I'm driving steppers with microsteps
09:27 AM Tom_L: dunno but that could vary with the driver
09:27 AM ZincBoy[CAON][m]: Depends. You need to be in the same position as the driver starts up in or it will jump.
09:28 AM roguish[m]: mrec: between steps the driver holds the fields in one position. this is why they steppers get hot even when not turning.... they're still drawing current
09:28 AM mrec: it should basically never jump if it was controlled via full steps
09:28 AM ZincBoy[CAON][m]: No. If the drive is off and restarts in a different phase drive mode it will jump.
09:28 AM mrec: (that's what I'm thinking at the moment, but I might be wrong)
09:29 AM ZincBoy[CAON][m]: Think winding A positive, B positive, drive off, then the drive starts in A negative, B negative.
09:29 AM mrec: ZincBoy[CAON][m]: I think I got your point and I understand thanks.
09:30 AM sensille: might need power off on a 4 step boundary
09:31 AM ZincBoy[CAON][m]: Yes, what ever the drive has as its "home" state.
09:31 AM mrec: I have around 100 SMD feeders and I want to draw as little power as possible
09:32 AM ZincBoy[CAON][m]: I know the gecko drives have a current reduction mode where they drop the currernt after the motor has been idle for a while.
09:33 AM mrec: https://i.snipboard.io/f7FPS3.jpg
09:33 AM mrec: that's just a test-setup
09:34 AM ZincBoy[CAON][m]: I am sure the modern stepper drive ICs have similar modes you can access through SPI or I2C.
09:34 AM mrec: I'm just using some cheap a4988 drivers at the moment
09:35 AM -!- #linuxcnc mode set to +v by ChanServ
09:35 AM mrec: there are some standby pins accessible, also the motor current can be regulated in my setup
09:35 AM Tom_dev: Unterhausen, Linux bookworm 6.4.0-rt6 #1 SMP PREEMPT_RT Fri Jun 30 09:12:44 CDT 2023 x86_64 GNU/Linux
09:35 AM mrec: (via software)
09:36 AM mrec: I just didn't go through all the features yet the motors work and I need to improve the adressing a little bit
09:40 AM ZincBoy[CAON][m]: You can use the Enable pin on the a4988. It just disables the output but keeps the internal logic active. As long as there is no torque on the motor it should restart without issue once enable is deasserted. The Sleep pin will shut down the internal logic and will cause a jump if you aren't in the home phase.
09:40 AM mrec: ther's also a standby pin
09:41 AM mrec: I will try carefully
09:41 AM mrec: thanks for the discussion it got me a bit further again
09:42 AM Tom_L: yeah, with the geckos my steppers barely get warm
09:42 AM ZincBoy[CAON][m]: No. The A4988 does not have a standby pin. Enable, Sleep, and Reset are the only pins that would impact the power state. (well other than vdd :))
09:45 AM Tom_L: Unterhausen, http://tom-itx.no-ip.biz:81/~webpage/cnc/kernel_test/6.4_kernel.png
09:49 AM mrec: ZincBoy[CAON][m]: I mistaked it with sleep
09:49 AM ZincBoy[CAON][m]: Makes sense. You do not want to use sleep in your application as it shuts down the internal logic as well.
09:52 AM mrec: I think for a better setup I will need the trinamic drivers
09:53 AM mrec: a4988 is just much cheaper
09:54 AM Tom_L: with fewer options
09:55 AM mrec: certainly
09:56 AM Tom_L: Unterhausen, http://tom-itx.no-ip.biz:81/~webpage/cnc/kernel_test/6.1_kernel.png
09:56 AM Tom_L: compared 6.1 to 6.4, not that much difference
10:10 AM Deejay: re
10:35 AM Unterhausen: Tom_L pretty good for no isolcpus
11:56 AM Unterhausen: Tom_L my kernel built with pcw's config is much better than when I tried to config
11:56 AM Tom_L: i used a basic config
11:57 AM Unterhausen: you're special
11:57 AM Tom_L: i wasn't sure his would work since it was marked ubuntu
11:57 AM Tom_L: i can try it
11:58 AM Unterhausen: no particular reason to try it, but so far I'm getting better than the lcnc kernel as well
11:59 AM Unterhausen: 7 glxgears, undersea youtube video, +/- 20us
11:59 AM Tom_L: you mentioned something about a rt desktop option
11:59 AM Unterhausen: just check to make sure it's full preempt
11:59 AM Tom_L: if you scroll down the list the preemt realtime is listed also
11:59 AM Tom_L: i did
12:00 PM Tom_L: i've no reason for me to test it unless you just wanna see a comparison of the 3
12:00 PM Tom_L: on same hardware etc
12:00 PM Unterhausen: My guess is that's a misinterpretation in the rules set up by xconfig
12:01 PM Unterhausen: I don't really need that, I inadvertently compared it on the same hardware through bumbling around
12:02 PM Tom_L: i'd be kinda curious if it would compile without errors
12:02 PM Unterhausen: which?
12:02 PM Tom_L: his config
12:03 PM Unterhausen: only error I got is it used an unusual compression that debian doesn't use, so I had to install that
12:03 PM Unterhausen: lz4
12:03 PM Tom_L: using xconfig?
12:03 PM Tom_L: i used that too btw
12:04 PM Unterhausen: you can change it in xconfig
12:04 PM Tom_L: where?
12:04 PM Unterhausen: there are kernel compression options
12:04 PM Unterhausen: I just found it easier to install lz4 and run make again
12:05 PM Unterhausen: this is the best latency I have seen on one of these computers
12:05 PM Tom_L: i've got other things to do atm anyway and i'll probably forget about it
12:05 PM Unterhausen: good idea
12:05 PM Tom_L: 6.xx is definitely better
12:06 PM Unterhausen: previously I was thinking about using a different computer because the latency was better
12:06 PM Tom_L: did you try the ping test?
12:06 PM Unterhausen: not yet, don't have my mesa network set up yet
12:08 PM Unterhausen: just noticed my isolscpu setting got transferred over to the new kernel
12:08 PM Unterhausen: that's convenient, unexpected
12:17 PM Unterhausen: I'm pretty happy I didn't have to turn off secure boot
12:17 PM Unterhausen: needless complications

02:38 PM fianna_noob0[m]: my .hal file has got these lines;
02:38 PM fianna_noob0[m]: net din-00 <= hm2_7i76e.0.7i76.0.0.input-04
02:38 PM fianna_noob0[m]: net din-01 <= hm2_7i76e.0.7i76.0.0.input-05
02:38 PM fianna_noob0[m]: net din-02 <= hm2_7i76e.0.7i76.0.0.input-06
02:38 PM fianna_noob0[m]: but the hal scope watch list doesn't show any of these inputs changing when I toggle any pins on teh TB6 high or low
02:39 PM fianna_noob0[m]: where do I find the mapping between the "hm2_7i76e.0.7i76.0.0.input-xx" pins and physical pins on the 7i76e or on the 25 pin expansion ports?
03:34 PM roguish[m]: 95 F today....
03:48 PM Tom_L: 98 here currently
03:49 PM travis_farmer[m4: 77F @ 67%rh
03:49 PM roguish[m]: at least it's not too humid here, only 30%
03:50 PM Tom_L: texas is getting hammered with heat
03:50 PM roguish[m]: no sympathy.........
03:50 PM travis_farmer[m4: lol
04:00 PM roycroft: we're getting hammered with heat
04:00 PM roycroft: it's that time of year
04:03 PM roguish[m]: forecast over 100 tomorrow......
04:03 PM roguish[m]: then dropping a bit
04:04 PM Tom_L: no sympathy :)
04:04 PM roguish[m]: no problem.... my new hvac just kicked the ac in
04:04 PM Tom_L: only 85 here tomorrow
04:05 PM travis_farmer[m4: 79F here tomorrow :-)
04:06 PM Tom_L: fianna_noob0[m], mesaflash can probably tell you that
04:07 PM travis_farmer[m4: though it sounds hotter if you use Kelvin scale... 299K
04:09 PM CloudEvil: Rankine.
04:11 PM roycroft: it's going to be 37 degrees on tuesday here
04:11 PM Tom_L: fianna_noob0[m], mesaflash -device 7i96e -addr 10.10.10.10 --readhmid
04:11 PM roycroft: that's 12 degrees on the newton scale
04:12 PM ithe2guu[m] is now known as iggw0[m]
04:12 PM * roycroft figures newton was a cool cat, so he has a cool scale
04:12 PM fianna_noob0[m]: I'll try this in the morning; I did readhmid a few days back when I was flashing and got an output so it's working, I just have the data saved on this pc so I'll have a look when i'm back by the linux machine tomorrow, thank you!
04:13 PM Tom_L: i think you can also use dmesg
04:13 PM Tom_L: dmesg -c to clear then run linuxcnc and do dmesg in a terminal while it's running
04:14 PM Tom_L: i forget what information it returns... haven't used it in a while
04:16 PM Tom_L: may need sudo for that
04:16 PM Tom_L: sudo dmesg
04:22 PM travis_farmer[m4: anybody else here used the comp mqtt-publisher.py ? i can't seem to figure out why it is so slow to report...
04:22 PM Tom_L: never
04:23 PM travis_farmer[m4: Hmmm
04:31 PM Scopeuk: There (on modern boxes) is dmesg -w which follows dmesg as it is written to, a little like tail -f
04:34 PM roycroft: s/modern/modern linux/
04:39 PM Scopeuk: Yes, I took that from context in the above discussion. Not going to work on windows. Not sure on bsd or osx
04:39 PM travis_farmer[m4: i think i figured out why it runs slow. that is, mqtt-publisher.py ( https://github.com/LinuxCNC/linuxcnc/blob/2.9/src/hal/user_comps/mqtt-publisher.py ) i found a delay in the loop. perhaps i can lower the "period" value and get faster response...
04:51 PM * Tom_L turns the switch from 'low' to 'medium' for travis_farmer[m4
04:51 PM roycroft: 10 minutes to go
04:51 PM roycroft: i'm ready for my vacation now
04:51 PM roycroft: i wonder if i should skip out 10 minutes early
04:51 PM Tom_L: been off for ~5hrs
04:51 PM CaptHindsight[m]: mqtt is supposed to be low latency
04:51 PM roycroft: i return to work on tuesday the 12th
04:52 PM travis_farmer[m4: been off for months :-(
04:52 PM Tom_L: roycroft, you should.. he will call you and make up for it
04:54 PM roycroft: i get to start my vacation by finishing that live edgr sanding
04:54 PM travis_farmer[m4: Hmmm, i suspect i need to go to store to get supper... unless i want to go to bed with a grumbling stomach...
04:55 PM roycroft: you can always make some stone soup for supper
04:59 PM * roycroft has to enable his .forward to his vacation message at exactly 3, so decides to stick it out at work until then
05:01 PM roycroft: yay! now i can start sanding and vacationing (which means now i am busier than when at work)
05:02 PM CaptHindsight[m]: better than standing in a soup kitchen line for 2 hours in 90F+ heat
05:06 PM Tom_L: if you switch kernels from the startup menu, how do you get it to keep that setting on the next boot?
05:06 PM CaptHindsight[m]: https://phys.org/news/2023-06-3d-world-smallest-wineglass-method.html made of glass
05:07 PM Tom_L: hardly get a buzz from that
05:08 PM CaptHindsight[m]: If you are comfortable with Linux terminal and commands, you can modify the /etc/default/grub file and add the following lines to it:... (full message at <https://libera.ems.host/_matrix/media/v3/download/libera.chat/3371e4f2832d5ecab37db4aa0e02974573e8e546>)
05:09 PM CaptHindsight[m]: https://itsfoss.com/boot-older-kernel-default/
05:09 PM roguish[m]: CaptHindsight: install grubcustomizer
05:09 PM roguish[m]: way easier
05:10 PM CaptHindsight[m]: but it might also wreck your grub setup
05:10 PM Tom_L: i've done that in the past but forgot
05:11 PM CaptHindsight[m]: it is not bullet proof
05:11 PM Tom_L: rebuild grub then
05:12 PM CaptHindsight[m]: grubcustomizer is another tool that "almost works"
05:12 PM roguish[m]: hasn't failed for me
05:12 PM CaptHindsight[m]: count your blessings
05:13 PM CaptHindsight[m]: and don't look a gift horse in the mouth
05:13 PM roguish[m]: never....
05:14 PM CaptHindsight[m]: expressions that you'll never hear from someone under 30 for $400 please
05:32 PM Tom_L: where does debian store the kernel files? i forget now..
05:33 PM Tom_L: /boot duh
05:34 PM Tom_L: no that's not it
05:34 PM Tom_L: nevermind..
05:38 PM CaptHindsight[m]: are most people (in the USA) off Monday as well next week?
05:41 PM Tom_L: GRUB_DEFAULT=0 right now, not 'saved' i assume it will take txt as well as a number
05:43 PM roguish[m]: oh joy, 99.3 now
05:44 PM Tom_L: i'll see your 99.3 and raise you 100
05:45 PM Tom_L: didn't think it was supposed to hit 3 digits here today

05:51 PM JT-Shop: 105°F here a couple of hours ago
05:51 PM XXCoder: 79f peak today
05:52 PM XXCoder: tues and wed and after wont be fun
05:54 PM CaptHindsight[m]: the humidity today must have been over 110%
05:55 PM CaptHindsight[m]: feels like the tropics
06:00 PM XXCoder: that'd mean that it was raining
06:01 PM XXCoder: or so close to 100% that you walking forward cause it to micro-rain into your clothes due to compacting air and going over 100%
06:02 PM JT-Shop: maybe we will get some rain the next few days
06:03 PM XXCoder: across 10 years here, we went from "what color was dry roads?" to almost "what is rain?"
06:08 PM roguish[m]: up another one... 100.2 now
06:14 PM roycroft: so now i get to figure out a different finish to use
06:14 PM roycroft: my counter top is finally done - fully sanded and ready for finish
06:14 PM roycroft: but i need to install it in less than 48 hours, and i don't think my usual finish will be nearly ready by then even as hot and dry as it is
06:15 PM XXCoder: diseccants and heated room?
06:16 PM Tom_L: put it out in the sun
06:16 PM roycroft: i'm going to go see if there's a wiping varnish that i can use
06:17 PM roycroft: shellac would work ok, but it's a little brittle for something that will be handled much and it's not very durable otherwise
06:17 PM roycroft: a wiping varnish with a bit of japan drier might work out
06:18 PM XXCoder: if it should last few days, something easily reversable?
06:18 PM XXCoder: then it can get proper finish afterwards
06:19 PM roycroft: i'm not going to deal with that
06:19 PM roycroft: nothing easily removable would work out well for the fair
06:20 PM roycroft: and i'm NEVER going to sand that countertop again :)
06:20 PM XXCoder: :)
06:20 PM XXCoder: yeah covering options
06:20 PM JT-Shop: a natural counter top for a hippy fair sounds right
06:20 PM XXCoder: thick epoxy top
06:21 PM XXCoder: maybe with river across it
06:21 PM XXCoder: ;)
06:21 PM roycroft: i have to get some pizza fixin's anyway
06:21 PM XXCoder: taco for me today
06:21 PM roycroft: and my favorite paint store is right on the way to the grocer's
06:21 PM roycroft: i had sopes for lunch
06:21 PM XXCoder: I was reminded of existance of taco bell yeserday
06:21 PM roycroft: but it's friday, so it's pizza night
06:24 PM XXCoder: whoo joe finally test firing his engine
06:24 PM XXCoder: been looking forward to that for while
06:26 PM XXCoder: I hate how low fps his videos are. and pretty overcompressed
06:28 PM roycroft: are they really that low res, or is your service provider defaulting to low res?
06:28 PM XXCoder: 720p in settings currently
06:28 PM roycroft: comcast have been doing that to me for a while now - while my speeds are really fast still, videos come in at 320i most of the time
06:28 PM roycroft: and when i'm a computer i can go into settings and set the resolution higher
06:28 PM XXCoder: I dont use comcast thankfully
06:29 PM XXCoder: we finally left them after many years few years ago
06:29 PM roycroft: but on my tv, well, it makes me want to watch them on my laptop, because the tv defaults to 160i most of the time
06:29 PM XXCoder: we started when it was company before the company comcast bought out
06:29 PM roycroft: the content, that is
06:29 PM roycroft: the commercials are still 1080p
06:29 PM XXCoder: and joes channel is only one I have this issue
06:30 PM roycroft: maybe you should join his patreon to help fund some new camera gear :)
06:30 PM XXCoder: this video is expecially bad, he keeps hitting camera and it vibrates
06:31 PM XXCoder: really bad to my permently dizzy brain
06:31 PM roycroft: alright, time to head off before the paint store closes
06:31 PM XXCoder: later, have great shop and food trip
06:33 PM Tom_L: sudo apt --purge autoremove seemed to work :)
06:39 PM Tom_L: JT-Cave, are inputs outputs working yet?
06:42 PM XXCoder: overcompressed example https://imgur.com/9dmubPi.png
06:42 PM JT-Shop: I've not tested them... I think most of main.hal is working, I need to work on it in the morning
06:42 PM * JT-Shop calls it a night
06:44 PM XXCoder: sorta reminds me of ich videos. qualty was pretty crappy there too
06:44 PM XXCoder: to point I couldnt watch any of his

07:06 PM Tom_dev: 6.1
07:15 PM Unterhaus_: Tom_dev, the main difference is max delay?
07:15 PM Tom_L: seems so
07:15 PM Unterhaus_: huh, 6.1 is better
07:15 PM Tom_L: on this system
07:15 PM Unterhaus_: what kind of ethernet card?
07:15 PM Tom_L: 7i96s
07:16 PM Tom_L: i could try a 7i92
07:16 PM Tom_L: or 7i90
07:16 PM Tom_L: 80? i forget
07:16 PM Tom_L: one is parallel and the other is ethernet
07:16 PM Unterhaus_: I meant the one in the computer
07:17 PM Tom_L: oh
07:17 PM Tom_L: adaptek i think
07:17 PM Unterhaus_: okay, I have intel on all of my comps. They might be better with the internet coalescing set right
07:18 PM Tom_L: some no name card...
07:18 PM Tom_L: realtek i meant
07:18 PM Tom_L: pcie
07:21 PM Tom_L: yeah you have to set that on intel cards
07:23 PM Tom_L: how do you list those?
07:26 PM Tom_L: yeah, both are Realtek
07:28 PM Unterhaus_: they got rid of ifconfig
07:28 PM Unterhaus_: bastages
07:29 PM Tom_L: lspci | egrep -i --color 'network|ethernet'
07:29 PM Tom_L: or 'network|ethernet|wireless|wi-fi'
07:30 PM Unterhaus_: firefox broke somehow
07:32 PM Unterhaus_: why is it so hard to kill an unresponsive program?
07:34 PM Tom_L: kill -9 number
07:34 PM Tom_L: ps -aux will get you the number
07:34 PM Unterhaus_: how do I find the number of firefox?
07:34 PM Tom_L: i think
07:34 PM jdh: killall -9 firefox
07:35 PM Unterhaus_: yeah, somehow firefox isn't named firefox
07:36 PM -!- #linuxcnc mode set to +v by ChanServ
07:36 PM Unterhaus_: firefox-esr for some reason
07:36 PM Unterhaus_ is now known as Unterhausen
07:36 PM Tom_dev: tom 1802 12.6 1.0 3239764 351432 ? Sl 19:34 0:06 /usr/lib/firefox-esr/firefox-esr

07:37 PM Unterhausen: killall -9 firefox-esr worked
07:37 PM Unterhausen: wonder what's wrong with it
07:37 PM Tom_dev: if you just want to kill one the first number is the process
07:37 PM Unterhausen: works now
07:38 PM Unterhausen: something about wayland taking forever to start up apparently
07:38 PM Unterhausen: according to the internets
07:42 PM Unterhausen: doesn't everybody start up their computer and open the browser to see what the kardashians did today?
07:43 PM Tom_L: who are they?
07:43 PM Tom_L: :)
07:43 PM Tom_L: i could care less
07:44 PM Unterhausen: I just thought of the most unlikely thing for us to do
07:44 PM Tom_L: we have quite a few selebs come to town to get their jets serviced
07:44 PM Tom_L: harrison ford comes alot
07:50 PM CloudEvil: Tom_L: Mainly simple tailors.
08:02 PM roycroft: well, i'll see how this goes
08:02 PM roycroft: i ended up getting watco's "danish oil"
08:02 PM roycroft: which i'm certain is not danish and contains little to no oil
08:03 PM roycroft: but you flood coat the part, let it sit 15 minutes, repeat, then wipe it dry, and it claims to be ready to use in 8 hours
08:03 PM roycroft: and it claims to be repairable
08:45 PM XXCoder: its TACO BELL TIME
08:45 PM XXCoder: man its expensive even for cheap ones now
08:50 PM CaptHindsight[m]: Unterhaus_: firefox-esr so that the debian devs only build it once very few releases vs every time
08:50 PM CaptHindsight[m]: Firefox Extended Support Release
09:15 PM roycroft: it's almost pizza time for me
09:16 PM XXCoder: yummy. gonna love cheapish food once a while lol
09:16 PM XXCoder: doubt I will go for a while for next one. cant really afford to do it often
09:19 PM liaoque: Have you ever tried Chinese food？
09:20 PM XXCoder: yes?
09:20 PM XXCoder: not sure how that relates, because eating at taco bell today doesnt mean I SOLELY eat ther.e
09:31 PM roycroft: i have eaten the product that taco bell sell before
09:31 PM roycroft: i cannot remember anything about it
09:31 PM roycroft: it has been many decades
09:32 PM XXCoder: trust me quality now sucks lol but once a while its enjoyable anyway
09:38 PM XXCoder: so many foods in taco bell has been infected with The Bean
09:38 PM XXCoder: and most of em would barely show em in board but its more than half of stuff
09:39 PM roycroft: i eschew fast food establishments and national chain establisments as much as possible
09:39 PM roycroft: i enjoy food too much to do otherwise
09:40 PM XXCoder: I just felt like obscenely junk food today.
09:40 PM * roycroft is about ready to assemble the pizza and pop it in the oven
09:40 PM roycroft: i need to do a wipe-down of the countertop in about 5 minutes, then i can finish dinner
09:40 PM XXCoder: I want to go get mongilian foods evenually but I already used out food budget
10:09 PM XXCoder: ugh
10:09 PM XXCoder: watching video, 2 guys is talking in front of table saw
10:10 PM XXCoder: table saw is not at safe place, though it is off. they hit table with hands few times.
10:10 PM XXCoder: I keep thinking "lower the damned blade already"
10:11 PM solarwind: Damn, the pressure vessel steel scrap I picked up is _impressive_
10:12 PM solarwind: I ground the edges to a polish with an angle grinder and left them outside in the rain and humidity for a week
10:12 PM solarwind: there's not a spec of rust
10:12 PM XXCoder: now theyre using 3d pen and wires ia laying across the blade, still not lowered lol
10:13 PM solarwind: It's not stainless, because there's surface rust from the 50+ years in a boiler, but it's insanely corrosion resistance
10:13 PM solarwind: Any guesses as to what the alloy can be? It _feels_ like mild steel
10:13 PM XXCoder: stainless can rust
10:13 PM XXCoder: not easily but possible
10:13 PM solarwind: yeah I know, this is not stainless though'
10:14 PM solarwind: doesn't spark like it, doesn't seem to work harden
10:14 PM XXCoder: hmm latter tells me its probably not stainless.
10:14 PM solarwind: feels very close to 1018 mild steel
10:14 PM XXCoder: stainless work hardens when you start prepping for work on it
10:15 PM solarwind: I may even build a foundry to cast it into more useful stock shapes, I don't know. And I have more coming next year, like tons of it if I want
10:16 PM solarwind: It's whatever alloy they specified to use in a boiler application in a school in the 1960s or so
10:24 PM roycroft: stainless steel can easily rust, given the right conditions
10:25 PM roycroft: not that i'm disagreeing with solarwind's assesment of the metalurgy of his material
10:26 PM XXCoder: it could be slighly modified alloying steel
10:26 PM XXCoder: fir increase to rust resistance.
10:27 PM XXCoder: its going to always have water in it
10:27 PM solarwind: I want to say it's some kind of weathering steel
10:27 PM solarwind: I wish I had an XRF gun
10:27 PM roycroft: if the pH is high, 303 and 304 will rust overnight
10:27 PM roycroft: 316 in days
10:28 PM solarwind: Yeah mine is just some kind of corrosion resistant alloy, I'm very curious to figure out what it is
10:33 PM roycroft: https://www.ebay.ca/itm/323302274328
10:33 PM roycroft: well, you can figure it out yourself
10:34 PM XXCoder: cheap at 10k usd
10:34 PM roycroft: plus $4k shipping
10:35 PM XXCoder: ultimately if guy is using a lot of mystery metals for making parts, it could be worth it
10:42 PM roycroft: it might just be a fun toy
10:42 PM XXCoder: yeah
10:42 PM roycroft: and if you're rich, probably a lot safer than going down to the titanic in a carbon fiber mini van
10:42 PM XXCoder: not one I cant afford lol
10:42 PM XXCoder: that is for sure.
11:59 PM CaptHindsight[m]: liaoque: Americanized Chinese food is available just about anywhere here, authentic Chinese is available in larger cities of if the owners are Chinese you have to ask them for what they are having
