12:24 AM miss0r: goodmorning
12:29 AM XXCoder: yo
12:29 AM XXCoder: skunkworks: dunno? but I wanna see it lol
12:29 AM jymmmm: Loetmichel: Interesting
12:29 AM XXCoder: in fact, why not make it say something? I know d is possible, O is dead easuy
12:29 AM jymmmm: Loetmichel: grinder with a cutoff blade?
12:29 AM XXCoder: what about other letters lol
12:29 AM jymmmm: skunkworks: Z, make a Z hole =)
12:29 AM jymmmm: or X
12:29 AM jymmmm: skunkworks: But D could actually be useful
12:29 AM XXCoder: im not too sure on what is possible. I guess it depends on what can be cleared out
12:29 AM jymmmm: skunkworks: If you make a D hole, I'll throw XXCoder down it =)
12:29 AM XXCoder: lol
12:39 AM miss0r: Do any of you guys have experience building your own exhaust manifolds? I am planinng on making a set for my v8 land rover. But I am having some issues settling on a material thickness. Why is it that all the stainless "banana" manifolds are made from 2.5-3mm wall thickness tubes? Any reason it could not be 1.5mm ?
12:39 AM XXCoder: it does get hot
12:40 AM XXCoder: stresses? maybe even deforming? dunno
12:47 AM miss0r: I dunno
12:47 AM miss0r: I heard someone mention 'wear'. But that was for diesel engines, where the particles can do that
12:47 AM miss0r: I need a new exhaust manifold for this old car. But I could only find one ready made, and it was ONLY sold as part of a complete exhaust kit.. for 1750.00£
12:47 AM XXCoder: pain
12:48 AM XXCoder: probably good idea to leave some excess on mating faces for that
12:48 AM XXCoder: laters
12:51 AM miss0r: see ya
01:56 AM Loetmichel: jymmmm: yes, that would work. but grinder with a circular saw blade would work even better
01:57 AM Loetmichel: we had that discussion with an insurance guy when we insured the workshop where we made out RVs.
01:58 AM Loetmichel: he complained that the man door in the big garage door had no bars across it. So friend got the sledgehammer and tried to smash it. Then took a similar piece of PC and used the torch... that convinced the inusrane guy that there is not bar needed ;)
01:59 AM Loetmichel: *insurance
02:22 AM XXCoder: miss0r: back
02:33 AM Centurion-Dan2 is now known as Centurion_Dan
08:08 AM dirty_d: I made an nc program to probe tool lengths and set the tool length offset (https://pastebin.com/nFPg9aQu) I want to run this on my cnc router after every tool change. can i configure linuxcnc to do this automatically, or do I need to modify fusion360's post to add `o<tool_probe> call` after every tool change, or otherwise manually add it to the code?
10:53 AM Eric__: all the unterhauses are already taken
11:02 AM jymmmm: Loetmichel: what man door, fort knox? lol
11:02 AM jymmmm: Why was it that jsut bought a UV lamp?
11:02 AM jymmmm: Who*
11:11 AM Loetmichel: jymmmm: big Truck shop with CNC machines in it
11:26 AM jymmmm: Loetmichel: ah
11:29 AM Loetmichel: [Insert extensive cussing in german here] HOT! *juggling the part* Will i ever learn that a chunk of alu gets REALLY hot when you press it for 20sec on a belt sander with 80 grit paper on it?
12:10 PM SpeedEvil: Loetmichel: use gasoline as a coolant
12:10 PM Deejay: hi
12:13 PM Tom_L: the shuttle does
12:13 PM Tom_L: fuel..
12:20 PM Loetmichel: SpeedEvil: nah. not the best smell
12:20 PM Loetmichel: IF anything i would use WD40 ;)
12:39 PM Eric__: I have a uv lamp to erase eproms. Haven't figured out how to get it in my lungs yet
12:40 PM Tom_L: you've seen sword swallowers ehh?
12:41 PM XXCoder: lol
12:47 PM skunkworks: I don't think the sword goes into the lungs...
12:47 PM XXCoder: unless its gasified sword heh
12:50 PM rmu|w: get your lung out. it will be unusable after UV irradiation anyways
12:56 PM methods_: try from the other side
01:00 PM pcw_home: rmu|w: not in favor of full body sunburns?
01:04 PM gregcnc: I read something were in the 40's? they UV irradiated blood
01:05 PM rmu|w: they did atmospheric tests of atomic bombs in the 40ies
01:06 PM gregcnc: is that related?
01:06 PM XXCoder: gregcnc: yeah uv treatment of blood. must be under certain percentage (like 3 to 4% before stop)
01:06 PM XXCoder: wonder if it ends up being emergacy last resort
01:07 PM miss0r: meh.. I *KNOW* I have some cable gland rubber inserts with two holes in'em, but I can only find the ones with four.. ! First world problems!
01:08 PM miss0r: This will make this job look alot less tidy!
01:08 PM miss0r: good evening, by the way :)
01:08 PM gregcnc: are you driving that tank while you can afford to do so?
01:08 PM rmu|w: gregcnc: only insofar as it show kind of the zeitgeist and mindset
01:09 PM XXCoder: hey
01:10 PM miss0r: gregcnc: Actualy I've started to rebuild it now.. while it is cheap... to... drive around in... yeah
01:10 PM miss0r: :) but it needs some TLC
01:10 PM miss0r: hence the new relay/fuse box I'm building now.
01:11 PM gregcnc: i have car maintenance to do, thermostats, valve cover gaskets, valve lash
01:12 PM skunkworks: so - any of you guys used any good erp software? (must include payrol)
01:12 PM miss0r: gregcnc: I would get three consecutive cases of "excess flood" if I started to list the stuff I have to do with this thing :D
01:12 PM miss0r: skunkworks: ERP?
01:12 PM skunkworks: enterprise resource managment..
01:12 PM miss0r: is that like the company books/accounting software?
01:12 PM skunkworks: yes
01:12 PM miss0r: then no :D
01:13 PM miss0r: oh
01:13 PM miss0r: I use Microsoft C5
01:13 PM miss0r: (the old locally installed version)
01:13 PM gregcnc: yeah there's more, but those are immediate, well maybe after they free us
01:13 PM miss0r: I use it for inventory, payroll, invoices & other accounting stuff
01:13 PM skunkworks: heh - we currently use navision (microsoft.)
01:13 PM skunkworks: but nobody is happy with it.
01:14 PM skunkworks: dynamics or whatever it is called now
01:14 PM miss0r: I didn't say I was happy. I am misurable everytime I do accounting stuff. I hate it. But that is not the softwares fault. I just don't like the deskjob part of being selfemployed
01:14 PM skunkworks: heh
01:15 PM miss0r: but the thing is; Theres alot of better options I know nothing of. I just use it because I know how to use it and can't be bothered to learn another system basically
01:30 PM miss0r: Mostly because I am slightly mad I am looking for an industrial alternative to the blinker relay. I am thinking something along the lines of a timer I can program to do a indicator light output. Set the down time, the up time ect. But it would seem industrial sometimes means alot of money or at least something that takes up far more space than I am willing to use for this. Do you guys know of some nice little
01:30 PM miss0r: device that does what I want? I basically just want it to be able to pull a relay at the output and that will handle the load.
01:31 PM rmu|w: ne555+bc817
01:32 PM miss0r: rmu|w: Yeah, I did think along those lines. But I was hoping for a ready build unit with some sort of IP class in the mid to high range.
01:32 PM rmu|w: add potting compound ;)
01:32 PM miss0r: IP65 or above would be preferred :)
01:32 PM miss0r: hehe yeah
01:33 PM rmu|w: maybe attiny is smaller and could directly drive your relais
01:33 PM rmu|w: maybe also cheaper
01:33 PM rmu|w: less external components
01:34 PM miss0r: true. I am considering just stuffing a brodersen timer relay in there, realy. Those thing saves lives :D
01:36 PM miss0r: but perhaps I am just insane. I can just get one of those "LED" type indicator relays
01:37 PM miss0r: They don't care much for the load at the other end, and won't give me that annoying "warning flash"
01:37 PM methods_: skunkworks: we use e2 shoptech lot of other shops seem to use job boss
01:37 PM methods_: i've never used job boss so i don't know if it's any better than e2
03:22 PM Rab: miss0r, I wouldn't call this industrial, but it sure is cheap: https://www.ebay.com/itm/183768729727
03:23 PM Rab: Lots of variants on eBay, Some have an electromechanical relay, some are 555-based.
03:23 PM miss0r: hehe. I don't mind paying 75-100usd for such a timer.. Just not double that
03:28 PM Rab: What about this kinda thing? https://www.omnical.co/products/allen-bradley-rockwell-automation-routeco/700-fea1tu22/106737874?locale=US
03:30 PM Rab: From here: https://ab.rockwellautomation.com/Relays-and-Timers/Economy-Timing-Relays#selection
03:30 PM miss0r: Rab: I'll probably go with this: https://uk.rs-online.com/web/p/timer-relays/0341373/?sra=pstk
03:31 PM miss0r: Mostly because I've loved using this particular brand of timer for many years
03:31 PM Rab: miss0r, looks legit.
03:32 PM miss0r: I usualy keep a few in stock, as they are 10.5-250v ac/dc supply
03:32 PM miss0r: realy handy for alot of things :)
03:42 PM miss0r: Rab: It is going into this box, that I just finished drilling and mounting stuff in: https://imgur.com/a/dklrmSN
03:50 PM miss0r: Thats it for tonight. See you around
03:54 PM Deejay: gn8
04:32 PM jymmmm: Anyone struggling to find things locally, like therometer?
06:16 PM jthornton: looks like Missouri will get 31 days of limited economic reopening
06:17 PM Tom_dev: i'm sure they'll 'soft' open us too
06:17 PM Tom_dev: next week iirc
06:18 PM jthornton: ours start May 4th
06:19 PM jthornton: I'll act like nothing has changed and continue on with my N95 and keep my distance
06:19 PM Tom_L: yesh something like that... 3rd or 4th here i forget
06:19 PM Connor: Yea.. they're opening up Tennessee too.. Knoxville will be phased opening May 1st.
06:20 PM jthornton: we are starting to see a decline in new cases here in Missouri
06:21 PM jthornton: most of them are not near me but my county is a leader in the area :(
06:21 PM Tom_L: go hide in the coop
06:21 PM jthornton: you got that shit right
06:22 PM jymmmm: Avian flu?
06:22 PM jthornton: we have 26 cases and most of the surrounding counties < 10
06:22 PM jthornton: Stoddard the east has the most next to us at 19
06:23 PM jthornton: well no Dunklin has 20
06:23 PM flyback: I hope pa gets a tornado and kills tom wolf
06:24 PM Connor: 214 confirmed, 183 recovered, 4 deaths.
06:24 PM jymmmm: If you decide to put your feet in the water, I'd suggest that you stock up. Cause if you do get sick, there's nobody around that is ginna help ya
06:25 PM jymmmm: FINALLY found my glass thermometer after 10 hours of looking for it, lol. The battery died in the digital one, and the stores have been out of stock for 2 months they say
06:28 PM jymmmm: And if you don't have antibiotics, PM me
06:41 PM flyback: yeah I hope someone stabs our state gov right in the chest
07:09 PM _unreal_: So I got the box from my "friend" I'M NOT pleased with the quality
07:15 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20200428_185705.jpg
07:20 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20200428_191604.jpg
07:25 PM flyback: YOU KNOW
07:25 PM flyback: with the economy the way it is
07:25 PM flyback: even a real shitty cnc machine might be valiable right now
07:26 PM flyback: making some widgets to keep existinf stuff going et
07:26 PM flyback: c
07:26 PM flyback: if you need a little cash
07:26 PM flyback: just be sure to drown anything you sell in lysol before you package it up :)
07:28 PM JavaBean: or make moonshine out of all that TP you hoarded, and distill it into a good cleaner
07:33 PM Eric__: can you make moonshine out of TP?
07:33 PM Eric__: google thinks I want to make ethanol, don't think that's possible, is it?
07:37 PM Eric__: there is a youtube about how to make drinkable alcohol out of TP and it appears the guy is alive, so maybe it works
07:37 PM methods_: why not just trade TP for alcohol
07:37 PM methods_: easier to get alcohol now than it is to get TP
07:38 PM flyback: god
07:38 PM flyback: i wasn't talking talking like book of eli here
07:38 PM flyback: sheesh
07:38 PM * methods_ puts away his braille bible
07:38 PM flyback: I was just saying people might be holding onto stuff for a while due to economie situation and being able to spit our a bracket etc
07:39 PM flyback: might be valiable right now
07:39 PM flyback: methods_, BMCC
07:39 PM * flyback hurls elmo50 at methods_
07:39 PM _unreal_: TP for alcohol.... TP for alcohol any takers
07:39 PM _unreal_: :)
07:40 PM methods_: triple ply?
07:45 PM jymmmm: methods_: half-ply, take it or leave it
07:54 PM CaptHindsight: $20 https://tibbo.com/store/plus1/specifications.html
08:05 PM jymmmm: CaptHindsight: where do I plug in the motors?
08:11 PM CaptHindsight: jymmmm: to da drives as per usual like
08:12 PM Eric__: not exactly economic since you have to buy some funny yeast https://www.youtube.com/watch?time_continue=2104&v=v-mWK_kcZMs
08:12 PM CaptHindsight: https://tibbo.com/programmable/showcase.html use kin proto it like dis project system
08:13 PM Eric__: spoiler alert, he does end up getting drinkable alcohol out of a roll of toilet paper
08:14 PM CaptHindsight: Eric__: did they try soaking up alcohol in it first?
08:15 PM CaptHindsight: https://www.sunplus.com/products/SP7021.asp

08:16 PM CaptHindsight: DEbian Buster image https://drive.google.com/file/d/1MpjDeUk4H-EXzaxpuywgbgRaM8YXoXjI/view
08:36 PM dirty_d: I made a thing https://photos.app.goo.gl/51A9CdsXksdooGhz7
08:36 PM dirty_d: good enough for wood!
09:16 PM _unreal_: dirty_d, interesting design.coomplicated? what is it?
09:18 PM Tom_L: tool touchoff
09:18 PM Tom_L: possibly a probe
09:20 PM Tom_L: https://www.centroidcnc.com/images/tt2_iso_600.jpg
09:33 PM skunkworks: https://www.youtube.com/watch?v=a7CO9gohaXE
09:34 PM Tom_L: saw the pic earlier.. pretty cool
09:44 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Cube/Cube_small2.jpg
09:44 PM Tom_L: they keep multiplying
09:48 PM skunkworks: Neat!
09:48 PM skunkworks: Does it help you unwind?
09:48 PM Tom_L: meh
09:49 PM Tom_L: i had 2 squared up so i figured i may as well run the last one
09:49 PM Tom_L: this kernel build is killin me though
09:58 PM Eric__: Tom_L did anyone help you with the kernel?
09:59 PM Tom_L: i'm trying to follow andy's directions
09:59 PM Eric__: in his github?
09:59 PM Tom_L: yes
10:01 PM Tom_L: taking a bit longer on the q1900
10:03 PM Tom_L: still not building right
10:13 PM dirty_d: _unreal_, yup, tool length probe
10:17 PM dirty_d: skunkworks, that is cool
10:39 PM Eric__: bought a $10 computer from Penn State, can't boot because they set the admin bios password
10:40 PM Eric__: may be a password jumper on the motherboard.
10:41 PM CaptHindsight: sometimes clearing CMOS will get you passed that
10:42 PM Eric__: dell has a jumper, sometimes
10:42 PM CaptHindsight: https://www.technibble.com/how-to-bypass-or-remove-a-bios-password/
10:43 PM Tom_L: anyone else build that rtai patch andy was working on?
10:43 PM CaptHindsight: https://bios-pw.org/
10:44 PM CaptHindsight: Tom_L: what is or is not happening?
10:44 PM Tom_L: i'm wondering what's returned with uname -a
10:44 PM Tom_L: i'm not sure if it's built
10:44 PM Tom_L: the kernel says the patches are there but uname doesn't show rtai
10:45 PM Eric__: I don't think the rtai kernel I have been running says rtai in response to uname
10:45 PM Eric__: could be wrong though
10:45 PM Tom_dev: Linux buster 4.19.114 #2 SMP Tue Apr 28 09:39:54 CDT 2020 x86_64 GNU/Linux
10:46 PM Tom_L: but that might be without the patches
10:46 PM CaptHindsight: Tom_L: have a link to Andy patch/s
10:46 PM Eric__: CaptHindsight so the password is not really set by what you enter. Not sure I understand how that works
10:46 PM Tom_L: https://github.com/NTULINUX/RTAI/blob/master/README.INSTALL
10:49 PM CaptHindsight: Tom_L: I'm asking him right now, he's booting into linux to check
10:50 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/Screenshot%20at%202020-04-28%2022-48-03.png
10:50 PM Tom_L: but
10:50 PM Tom_L: that's while building a kernel
11:34 PM veegee: Is the sheet metal used for computer parts (cases, the enclosure for internal CDROM drives, etc.) galvanized?
11:35 PM veegee: I have so much old junk, but the sheet metal is nice and I want to weld it
