06:16 AM JT-Cave: morning
06:28 AM lcnc-relay: <travis_farmer@> Morning
08:58 AM roycroft: hello
08:58 AM roycroft: and i can say that it's not just morning, but a good morning
09:01 AM bjorkintosh: fantastic!
09:01 AM bjorkintosh: mending++?
09:08 AM roycroft: yeah, it was really easy getting out of bed today
09:08 AM roycroft: i think i'm going to try a night without oxycodone
09:08 AM roycroft: being done with that will be a big step forward
09:22 AM roycroft: i may be exchanging titles for cash today as well
09:24 AM roycroft: i'm a little sad that all my vw stuff is going away, but realistically, i'm not going to get around to fixing up those buses an making them roadworthy again
09:24 AM roycroft: i gave up on the ev project years ago but never got rid of that bus
09:24 AM roycroft: the '74 camper bus i was hoping to get running again and using for road trips after i reture
09:24 AM roycroft: retire
09:26 AM rdtsc-w: one door closing is another door opening in disguise
09:27 AM lcnc-relay: <skunkworks8841@> I have most of the parts to redo dads 350 ford pickup. I have not yet decided if I am actually going to do it.
09:27 AM lcnc-relay: <skunkworks8841@> Stella wants me to...
09:29 AM roycroft: i wish my pickup got better fuel economy
09:29 AM roycroft: for the road trips, pulling a small trailer with the pickup would be ideal
09:29 AM roycroft: but i get about 15mpg with it
09:29 AM roycroft: realistically, though, that's not all that bad
09:30 AM roycroft: the vw camper bus only got 21mpg
09:30 AM roycroft: so it's not that huge a difference
09:31 AM roycroft: and if i'm honest, while i love driving a vw bus, i'm planning on making road trips to the desert in southeastern oregon, and to other hot areas like nevada, new mexico, and arizona
09:31 AM lcnc-relay: <skunkworks8841@> I think we have close to the same truck..
09:31 AM roycroft: my pickup has air conditioning
09:31 AM lcnc-relay: <skunkworks8841@> 6 liter diesel?
09:32 AM roycroft: mine's a 2001, with full length bed, crew cab (or whatever the bigger cab is called), and the 7.3l diesel
09:32 AM lcnc-relay: <skunkworks8841@> ah - this is a 2004 or 6 - I don't remember - short box crew cab.
09:33 AM rdtsc-w: Farmcraft just did a series on replacing rocker panels, to much fanfare
09:34 AM lcnc-relay: <skunkworks8841@> I have a replacement cab.. good rockers
09:34 AM lcnc-relay: <skunkworks8841@> but - it will be a lot of work.
09:34 AM lcnc-relay: <skunkworks8841@> sand blasted and painted frame.. So everything needs to be transfered.
09:34 AM roycroft: we don't have rust here
09:35 AM lcnc-relay: <skunkworks8841@> must be nice.. we live in the salt belt
09:35 AM roycroft: that's what was so frustrating about selling the vws
09:35 AM lcnc-relay: <skunkworks8841@> the frame on the truck currently is shedding flakes of rust .,
09:35 AM roycroft: folks would be offering me like $200 or $500 for them
09:35 AM roycroft: the guy who is buying them did the right thing when he came to look at them
09:36 AM roycroft: he immediately looked at the rockers and thumped on the floorboards
09:36 AM roycroft: and they were sold immediately, because the rockers and floorboards are solid
09:36 AM roycroft: that's why folks back east will pay $8k-$10k for a gutted bus from my part of the world
09:37 AM roycroft: all they have back east are rust sculptures that resemble vw buses
09:47 AM roycroft: https://roycroft.us/2001_Ford_F350_7.3_Powerstroke_4x4.jpeg
09:47 AM roycroft: there's some pics of the dealer listing for my pickup
09:49 AM lcnc-relay: <skunkworks8841@> that looks nice
09:49 AM lcnc-relay: <skunkworks8841@> Long.. lol
09:52 AM bjorkintosh: yes. for transport crew and material.
09:53 AM lcnc-relay: <skunkworks8841@> or for me.. Kids..
09:53 AM roycroft: way too long
09:54 AM roycroft: but since so many pickups are bought by urban cowboys these days, who never use them for work but need to schelp kids around in them, it's all but impossible to buy one without the crew cab these days
09:55 AM roycroft: i must admit that the crew cab has come in really handy for hauling things that cannot be exposed to the weather
09:55 AM roycroft: but i'd rather have gotten a rig without that
09:55 AM roycroft: they just don't seem to exist
09:56 AM roycroft: the original 7.3l powerstroke engine, which my pickup has, is arguably the best small diesel engine ever buit
09:56 AM roycroft: built
09:57 AM roycroft: that's a big reason i bought that vehicle, and was ok when the dealer would not haggle on price
09:57 AM roycroft: it was priced well to begin with - i basically got a nice diesel truck for the price of a gasoline truck
09:57 AM roycroft: and it had new glow plugs, injectors, and fuel rail wiring when i got it
10:15 AM roycroft: geeze
10:15 AM roycroft: now my boss is pissed off about a customer
10:16 AM roycroft: we've been hosting their email for decades, and have been forwarding it to their gmail account as well
10:17 AM roycroft: the customer claims to have cancelled the email account years ago, and my boss hasn't been billing for it, but it's still active on the system, and he wants to bill them up until the last time they accessed it
10:17 AM roycroft: and he's pissed off at me because i don't keep mail logs going back several years, so i can't tell the last time the customer accessed the local account
10:18 AM roycroft: i'm thinking maybe he should have done a little better job on the bookkeeping end?
10:59 AM Rab: roycroft, seems like teeing into the washing machine would be an 80% solution until things settle down, as long as there's a drain.
11:00 AM roycroft: the drain is the issue, and i'm still trying to wrap my head around how that's going to work
11:00 AM roycroft: but yeah, i think that can work
11:01 AM roycroft: and i might even get some of that cheap, thin plastic sheet stuff that is supposed to go over sheetrock as an interim wall covering
11:01 AM roycroft: i think that stuff is <$20/sheet,and i only need 2 sheets to cover the wall opening
11:02 AM roycroft: if i put that up without worrying about sealing it, and using screws, it would keep minor splashes, etc. away from the stud wall
11:02 AM roycroft: and would be trivial to remove and replace later with sheet rock
11:03 AM Rab: Not a fan of sheetrock in laundry room applications anyway. It's a common area for leaks which wreak terrible destruction on sheetrock.
11:04 AM roycroft: long term, i'd like to put up ceramic tile on the walls
11:04 AM Rab: Lots of piping, unheated so prone to freezing.
11:04 AM roycroft: but that's expensive
11:05 AM roycroft: my laundry room is heated
11:05 AM roycroft: and the plumbing will all be new
11:06 AM Rab: I like the idea of plastic sheet, or the cheapest 3/16" plywood underlayment would work.
11:07 AM bjorkintosh: Rab: tile it like a bathroom then.
11:08 AM Rab: bjorkintosh, if the plumbing's in the wall then you have to demo the tile to get to it.
11:09 AM Rab: Every time I have to redo plumbing under tile I try to put in an access hatch on the other side of the wall.
11:14 AM lcnc-relay: <skunkworks8841@> I think the first 3 feet off the floor is dura-rock.. then the rest sheetrock
11:17 AM lcnc-relay: <roguish> roycroft: use copper pipe everywhere. rats like that plastic pipe stuff....
11:20 AM Rab: I put PEX through my attic, which has had occasional rat activity over the decades, and I was paranoid enough that I jacketed it with armored electrical conduit.
11:21 AM Rab: Probably not any faster, cheaper or easier than copper in the end, but the flexibility was helpful for what I needed to do.
11:29 AM roycroft: we don't have rats around here
11:29 AM roycroft: that is good
11:30 AM roycroft: even better (though not an issue with pex), NO NEUTRIAS!
11:40 AM lcnc-relay: <roguish> you just haven't seen the rats..........they are everywhere........
11:41 AM lcnc-relay: <roguish> i've repiped my entire house. only mistake was putting hot water into the toilet......doh
11:42 AM roycroft: well i can't afford the time nor expense of copper right now
11:42 AM roycroft: this house is plumbed with polybutyl pipe, which is utter crap
11:42 AM roycroft: it needs to be redone completely
11:43 AM roycroft: polybutyl was really popular in the '80s and '90s, but now it's prohibited by code because it's not very durable
11:43 AM roycroft: pex is my only real option right now
11:44 AM roycroft: i don't know why folks don't do this, but when i redo the laundry room plumbing i'm going to put a hose bib on the outside, as that side of the house has none
11:44 AM roycroft: and i've decided to install both hot and cold hose bibbs
11:44 AM roycroft: it would be really nice to have hot water outside the house
11:45 AM * bjorkintosh blinks.
11:45 AM bjorkintosh: sounds really decadent! Never thought of that before!
11:45 AM roycroft: i get why it's not ever done in parts of a house where there is no hot water already, but if you're going to put a hose bibb outside a laundry room, kitchen, or bathroom, why not do both hot and cold?
11:45 AM bjorkintosh: so... futuristic, yet so possible.
11:47 AM lcnc-relay: <roguish> watch the codes......
11:47 AM roycroft: i'm not super familiar with plumbing codes
11:48 AM roycroft: it doesn't seem to me like there should be a code restriction on a hot water hose bibb, but i'll check before i do that - thanks
11:49 AM roycroft: and if there is, perhaps what i should do is install an outdoor sink with a gravel pit drain and bring the hot and cold water to that, assuming code permits it
11:49 AM roycroft: a "garden sink", if you will
11:49 AM roycroft: for cleaning produce that i pick from the garden before bringing it inside
11:50 AM lcnc-relay: <roguish> roycroft: check this out. you can probably find your state codes https://public.resource.org/pro.docket.2015.html
11:50 AM lcnc-relay: <skunkworks8841@> you could have 1 bib - with 2 valves going to it in the house..
11:50 AM roycroft: and if code does not permit it, i'll find another way to do it
11:50 AM lcnc-relay: <skunkworks8841@> one hot - one cold - then you could also mix it..
11:51 AM roycroft: maybe a stub pipe from the inside to the outside, where i can hook a hose on the inside from the sink to the stub for hot water
11:51 AM roycroft: i know where the state plumbing code is
11:53 AM roycroft: putting a mixing valve indoors that feeds a single outdoor hose bibb may be a really good idea, now that i think about it more
11:54 AM roycroft: i'd just leave it on cold most of the time, and adjust it on the occasions where i need warm/hot water
11:55 AM Rab: I have occasionally wanted hot water outside badly enough to hook a garden hose up to the water heater flush valve. A permanent bib would be awesome for outdoor cleaning, degreasing, etc.
11:56 AM rdtsc-w: frost-free of course
11:56 AM roycroft: my sink for the laundry room is a commercial bakery sink - big, stainless steel thing
11:57 AM Rab: But I attach backflow preventers to all the bibs, and for hot water it'd be even more important...don't want anything nasty getting into the system and incubating.
11:57 AM roycroft: code requires a 2" drain on a service sink, which this pretty much is
11:57 AM roycroft: but it requires a 1-1/2" drain on a laundry sink, which is arguably the use for this one
11:58 AM roycroft: the issue is that a 1-1/2" drain fills the stud cavity - upgrading to 2" would require a thicker stud cavity, and i have no room to build that out
11:58 AM roycroft: the sink is too big for even a 1/2" furring of the wall
11:58 AM roycroft: so i'm going to have to call it a "fancy laundry sink"
11:59 AM roycroft: and yeah, i intend on a backflow preventer for any hose bibbs i install - i've always done that
11:59 AM lcnc-relay: <roguish> build a 2x6 stud wall..... more room, better insulation
11:59 AM roycroft: sure, but as i said, i can't do that
11:59 AM roycroft: i don't have the room, unless i pushed it to the outside wall, which would be a major remodel
12:00 PM roycroft: the sink will sit flush with the outside wall, and sticks out to within a fraction of an inch to the door opening
12:00 PM roycroft: it *barely* fits as is
12:04 PM lcnc-relay: <roguish> crappy day here. supposed to have been clear and cool. instead, drizzly and cold
12:04 PM roycroft: it's sunny her, and will be reasonably warm
12:07 PM lcnc-relay: <roguish> good thing I got my nice ride in yesterday
12:21 PM roycroft: i have to go to my storage unit today or tomorrow
12:21 PM roycroft: that should be fun - the units are cargo containers, and i hope i am able to open the one i need to get into
12:22 PM roycroft: i'm pretty sure the keys for one of my vw buses is in the unit, so i really need to get into it before the weekend
12:30 PM rdtsc-w: Fab Q: building a medium-sized, locking articulating arm for mill touchscreen. 1.25in outer (black steel) pipe, 1.0in inner pipe. Four compact, adjustable, angular locking joints using the larger pipe, connected by three short sections of smaller pipe.
12:30 PM rdtsc-w: Using 7/16in handle-screws from outer pipes to bite into inner pipes and prevent rotation. Considering welding a nut to the outer pipes, so that the handle-screws have more threads to utilize. But welding the nuts is going to soften them, right?
12:30 PM rdtsc-w: How would you approach this? Could: A) do not use an extra nut, and rely on outer pipe threads only.
12:30 PM rdtsc-w: B) drill the outer pipe to completely clear threads, and rely on nut threads only.
12:30 PM rdtsc-w: C) tap the outer pipe, screw a nut onto the tap, tack the nut in place, remove tap, then weld. Run tap through after to ensure threads are fine.
12:33 PM Rab: Black pipe is pretty soft already. I would rather use a nut than threads in the piping.
12:36 PM Rab: I think I would go with option B.
12:38 PM rdtsc-w: wonder if the nut can be "long-tack-welded" and quenched, just on two sides, to try and retain some of its strength. Never tried such with TIG, but sounds iffy
12:40 PM roycroft: i've done this before, and used option b
12:40 PM roycroft: and i've not worried about softening the nuts, but i also have not needed to torque the set screws very much
12:40 PM roycroft: it usually doesn't take a lot to do the holding
12:41 PM roycroft: there is also option d, which i have used with success in the past
12:41 PM roycroft: instead of drilling out the pipe, you cut a tab into it - cut three sides of a rectangle, and if the pipe wall is thick, partially cut the fourth side, to create a flap
12:41 PM roycroft: then weld the nut over that
12:42 PM roycroft: that way, the flap is pressing against the inner pipe, and not the end of the screw, which greatly reduces the possibility of galling the inner pipe, making it both hard to adjust and hard to keep a minor adjustment
12:42 PM roycroft: that's a lot of work, so there is also option 3
12:42 PM roycroft: which is option b, but use a brass-tipped set screw
12:44 PM Rab: Yeah, I was thinking that the screw was going to raise a burr on the inner pipe with every use. The flap would prevent that.
12:45 PM roycroft: the set screw would raise a burr on the flap, but that doesn't matter, because it will always contact the flap in the same place
12:45 PM JT-Mobile: Yo
12:45 PM JT-Mobile: Yo
12:45 PM roycroft: ma
12:46 PM rdtsc-w: all good ideas, thanks. gotta get this design out of the planning stage
12:46 PM JT-Mobile: I thought it was broken
12:49 PM roycroft: https://www.mcmaster.com/90669A578/
12:50 PM Rab: "7/16in handle-screws"
12:50 PM roycroft: oh, you have the screws already
12:51 PM Rab: Could use a slug of brass in the hole, it would stay captive unless the inner pipe is removed.
12:51 PM roycroft: potentially you could turn a brass tip for them with a threaded stem, drill and tap the end of the screw, and use some red threadlock to marry the two together
12:52 PM rdtsc-w: yep, like what is commonly used on a lawn mower to hold the handlebars together, just beefier. Could round the tip slightly I think
12:52 PM roycroft: and yeah, a slug of brass would work
12:54 PM Rab: I like some type of clamping system rather than a screw pressing into the sidewall of the inner pipe, but it would be more elaborate from a fabrication standpoint. Black pipe is pretty hardcore depending on the weight of the touchscreen box, I wonder if EMT slit and clamped would hold up.
12:54 PM roycroft: i can tell you from experience that you don't want to do steel on steel, especially if the inner tube fits the outer tube closely
12:55 PM rdtsc-w: there is likely 0.064in gap between the two pipes, so close but not too close.
12:56 PM roycroft: close enough that the first time someone turns the handle screw really tight you won't be able to adust the inner tube any more
12:56 PM roycroft: but still better than a 0.006" gap
12:59 PM lcnc-relay: <schoch_@> meisterdippel@ are you aware of anyone doing closed loop motion with linear scales and RIO?
12:59 PM roycroft: the flap thing works really well - i've done it several times and it has never failed me
12:59 PM roycroft: and i have always cut the flap on the milling machine with a really small cutter
01:01 PM Rab: I took the swing arm off my Deckel because I was getting rid of the huge control, but I might put it back on...it's really pretty robust. Not vertically poseable, though. https://www.fpsgermany.com/wp-content/uploads/FPS-Bilder/Maschinen/DECKEL/CNC/Auf-Lager/FP2-NC-2801-100-NC-Teilapp-Dialog4/FP2-NC-2801-100-nc-teileapp-dilaog4-01-1024x1024.jpg
01:05 PM rdtsc-w: looks quite beefy. surprised they didn't run the wiring through the bottom section; seems large enough... but any electrican will tell you "more than 90 degrees bend and forget pulling" ;)
01:06 PM JT-Mobile: 4 90s max
01:07 PM Rab: Deckel was in love with this goofy pvc hose, it's all over the machine, but it works pretty well to contain the massive amount of wiring.
01:08 PM Rab: Unfortunately a lot of it has split into segments on my machine, which isn't as clean as the one in the picture.
01:09 PM rdtsc-w: a showpiece has done no work. :)
01:11 PM Rab: Indeed! Although they are more tool & die than production machines, sometimes living in shockingly clean environments.
01:12 PM JT-Mobile: I really need to make a scrap run and clean the machine shop up after the empire project
01:13 PM rdtsc-w: are they all done?
01:14 PM JT-Mobile: Just 2 proximity switches to go
01:16 PM rdtsc-w: the finish line is in sight :)
01:16 PM JT-Mobile: Yup
01:17 PM roycroft: when i owned a fiat, many many years ago, there was a local repair shop who specialized in italian cars
01:17 PM JT-Mobile: Already sent the last invoice
01:17 PM roycroft: this was up in bellingham, so it was a really long time ago
01:17 PM roycroft: anyway, they liked to keep a clean shop
01:17 PM roycroft: the engine rebuilders all wore white lab coats, and they stayed white
01:17 PM roycroft: the rebuild room was as clean as an operating room
01:18 PM roycroft: i do not think the five second rule applied there at all - it was more like the infinity rule
01:18 PM Unterhaus_ is now known as Unterhausen
01:18 PM roycroft: some tool and die shops are like that
01:22 PM JT-Mobile: My shops are a disaster zone
01:24 PM roycroft: mine is kind of
01:24 PM roycroft: but not totally
01:27 PM rdtsc-w: I'll clean tools occasionally, but my workspaces are usually pretty cluttered/busy/in-process, which usually means "well used" looking... i'd like machines to be spotless but spend far more time using them than cleaning them
01:33 PM * JT-Mobile heads back to the barn
01:38 PM roycroft: in a woodshop there is almost always sawdust
01:38 PM xxcoder: just keep it under air-fuel explosion levels
01:40 PM roycroft: i keep it well under that level
01:40 PM xxcoder: wise. yeah that event was pretty infamous
01:41 PM roycroft: i have a dust collector for the big machines, a festool extractor for the hand-held machines and an overhead dust filter to get the stuff that's floating in the air
01:44 PM roycroft: the festool extractor and overhead filter filter to 0.5µ
01:44 PM roycroft: the dust collector to 1µ, but it exhausts to the outside, and does not recirculate shop air
01:44 PM xxcoder: yeah sounds like clean system
01:45 PM roycroft: it is for the most part, but there's always some dust/chips
01:45 PM xxcoder: in least its not glitter'
01:45 PM roycroft: my sanders get about 99% extraction - that is the most underrated feature of festool gear
01:45 PM roycroft: but routers, even the festool routers, throw chips about
01:46 PM roycroft: it's almost impossible to extract from a router well
01:46 PM roycroft: it's good enough with my shaper origin that as long as i have the overhead filter running i don't feel a need to wear a respirator when using it
01:47 PM roycroft: but when i'm routing edges or using the big routers i usually wear a respirator even though i have some extraction
01:47 PM roycroft: or i take the work outside and do the routing on my driveway or in my back yard
01:48 PM xxcoder: I wonder if you could 3d print an edge vacuum, its flat and wide, and its sticked down into surface, being outside of area tool need to go around on
01:49 PM xxcoder: or have flanges where you can put weights or clamp on to make it stay
01:51 PM roycroft: i don't think there's a reasonable way to contain all the chips from a routing operation
01:51 PM roycroft: nor a wood lathe operation
01:51 PM roycroft: some operations are just messy, period
02:02 PM lcnc-relay: <meisterdippel@> schoch_@: yes and no 🙂 i have test it but not in production, it's the same as rotating AB encoder
02:03 PM lcnc-relay: <schoch_@> thanks, i'm considering finally ditching grbl for my mill
02:03 PM lcnc-relay: <schoch_@> but i'm also considering just making a dedicated PCB mill
02:03 PM lcnc-relay: <schoch_@> also, maybe both things.
02:04 PM lcnc-relay: <schoch_@> what's next for RIO meisterdippel@ ? you have a roadmap or taking a break from it?
02:10 PM lcnc-relay: <meisterdippel@> under heavy development 🙂
02:10 PM lcnc-relay: added some support for parport and rpi-gpio (for extra io's)
02:10 PM lcnc-relay: at the moment i'm building a CAN-Bus controller to control my odrive
02:15 PM lcnc-relay: <schoch_@> i was entertaining the idea of simplefoc driven motors
02:16 PM lcnc-relay: <schoch_@> I lucked into a ton of gimbal motors which likely are plenty to drive a pcb mill
02:16 PM lcnc-relay: <schoch_@> i havn't seen much in the way of simplefoc + motion planner tho.
02:17 PM lcnc-relay: <schoch_@> i have some 200w dc servos and i'm lazy
02:20 PM lcnc-relay: <meisterdippel@> odrive is realy cool and the clone from MKS is cheap (mks-odirve / mks xdrive)
02:25 PM roycroft: success - i was able to open the storage container
02:25 PM roycroft: and as a bonus, i know what my current limit is for doing that kind of stuff, because i was pretty much at my limit
02:26 PM roycroft: oh, i also found the keys i was looking for, so i guess that's the bigger win
02:31 PM rdtsc-w: sounds like everyone is leveling up :)
02:47 PM bjorkintosh: True.
02:47 PM bjorkintosh: My hoarding of hardware has finally paid off. I have an old hp from 2006 which just happens to have a serial port and a parallel port.
02:47 PM bjorkintosh: it's now running ubuntu 24.04
02:49 PM bjorkintosh: it's only 19 years old, I know. but ... no other machine here has an rs232 serial port
02:58 PM bjorkintosh: hah!
02:59 PM bjorkintosh: and the serial port works.
03:06 PM lcnc-relay: <mikemader@> Oddly enough, you can still get motherboards with com port headers on them
03:07 PM lcnc-relay: <mikemader@> I bought an X99 motherboard (Granted it has an older Xeon processor) for a home lab server last year, and it has them.
03:09 PM bjorkintosh: I bet you this computer cost me 5 bucks 4 years ago. I bought it specifically because it had all the ports on them. with an SSD it's super fast.
03:09 PM bjorkintosh: I actually forgot all about it until I started moving things around to clean up a little.
03:18 PM lcnc-relay: <mikemader@> That is great, best of all you saved it from being e-waste!
03:21 PM lcnc-relay: <mikemader@> I had an HP of close to that generation that was originally my "shop pc" that run WinXP. I was going to use it when I started building my CNC back in 2016/2017. The build got delayed till 2021 due to life happenings. By then, I went with a MESA board, and used an HP Mini for it. I came across that PC a couple months ago when cleaning things up. Tried to get it to boot, but alas it was completely dead.
03:21 PM lcnc-relay: <mikemader@> * vintage
03:21 PM bjorkintosh: mikemader I bought it from an e-waste recycler.
03:22 PM lcnc-relay: <mikemader@> Awesome!
03:28 PM roycroft: i have a vintage vt320 in excellent condition, if anyone wants a real rs232 terminal
03:29 PM roycroft: but they are collectable now, and i want some actual money for it
03:29 PM roycroft: like $400
03:30 PM bjorkintosh: you should absolutely get real money for it.
03:31 PM roycroft: it's yellowed over the years, as they all have
03:31 PM roycroft: i have not tried the h2o2 bleaching trick on it, but i may do so before i sell it
03:34 PM bjorkintosh: never beige!
03:37 PM rdtsc-w: The 8-Bit Guy has a series of videos about "retro-bright"
03:39 PM rdtsc-w: testing UV exposure source and time, method, etc
03:47 PM bjorkintosh: I had an old SGI indigo 2 from '94 thereabouts. I should have kept it.
03:51 PM lcnc-relay: <mikemader@> I remember when the company I was working for at the time, late 90's, early 00's, one of our graphic designers got a SGI workstation.
03:52 PM lcnc-relay: <mikemader@> I was tasked to help him set it up. I was so disappointed that it was a Windows PC with a decent video card, but really just had the branding.
05:43 PM Unterhausen: I bought some sgi workstations when it was still unix. Shockingly expensive by today's standards
05:44 PM Unterhausen: I swear nobody ever did anything with them
05:46 PM roycroft: they were
05:46 PM roycroft: and i think when the moved to intel was when the intel cpus started outperforming the sparc chips at a lower cost
05:46 PM roycroft: sgi engineers basically held their noses and redesigned for intel
05:47 PM bjorkintosh: Unterhausen: they were heavily used for 3D cad.
05:47 PM roycroft: i don't think the framebuffers were ever the same quality though
05:47 PM bjorkintosh: the machine I bought off ebay, was used to run CATIA for the f15 fighter or something like that. there was a sticker on the harddrive.
05:48 PM roycroft: they were also used heavily in the film industry by companies like lucasfilm
05:48 PM Unterhausen: Nobody at my work ever used those particular computers. When I worked on fighters, we all had an SGI
05:49 PM Unterhausen: after work we all had dogfights
05:49 PM bjorkintosh: yes. famously in that one scene in jurassic park. https://www.youtube.com/watch?v=JOeY07qKU9c "It's A UNIX System!" | Jurassic Park | Science Fiction Station
05:49 PM bjorkintosh: Unterhausen: what software did you use on the SGI?
05:50 PM Unterhausen: slipping my mind right now. One of the fea programs
05:51 PM bjorkintosh: ah I see.
05:51 PM Unterhausen: I found out later that when the gerneral dynamics contractors gave tours, they ran my dynamic simulation of a valve poppet
05:52 PM Unterhausen: They only ever did static load analysis
05:52 PM roycroft: i just watched jurassic park a couple months ago for the first time
05:53 PM roycroft: i had never gotten around to it
05:53 PM roycroft: it was entertaining
05:53 PM roycroft: albeit a far stretch from anything resembling reality
05:53 PM Unterhausen: would have been fun to use the computer geek's error sound on a mac
05:54 PM Unterhausen: I used to change the chime on my mac to something obnoxious when I was going to be away from work, that would have been perfect
05:56 PM Unterhausen: in the days before macs had a login
06:22 PM JT-Shop: ups is getting to be a pia to use... surcharge for cc payments and now they force you to use some new think OAuth 2.0 whatever that is
07:14 PM -!- #linuxcnc mode set to +v by ChanServ
10:20 PM lcnc-relay: <big_kevin420@> late to the jurassicpark party
10:21 PM lcnc-relay: <big_kevin420@> but a few years ago i spent a while trying to get that 3d file visulaizer working on raspberrypi
10:21 PM lcnc-relay: <big_kevin420@> but at the time, there was some graphics driver issue so i could get it working, but it looked dark and wierd
10:52 PM roycroft: hi
10:53 PM xxcoder: o/
