01:30 AM _unreal_: cant sleep
01:35 AM _unreal_: no idea why
01:35 AM XXCoder: you need to burn off energy
01:35 AM _unreal_: you have no idea what I did at work
01:35 AM XXCoder: or be ver bored. lay in bed in darkness. dont read, dont play with phone or whatever
01:35 AM _unreal_: I was sweating my ass off
01:35 AM _unreal_: working in a hard to get to area on this boat today. grinding fiberglass got home had 3 beers. you would think I'd be OUT
01:35 AM _unreal_: I am WIDE awake
01:35 AM _unreal_: 2:30am
01:35 AM _unreal_: My monitor is BLINDING but thats to be expected
01:35 AM XXCoder: get in bed turn everything digital off heh
01:35 AM _unreal_: Not sure what I want to do to morrow.
01:35 AM _unreal_: Thats not going to put me out
01:35 AM _unreal_: woke up form a REALLY weird ass dream though.
01:35 AM _unreal_: I think tomorrow I need to start getting that motor controller finilized and working for the new cnc machine.
01:37 AM _unreal_: and I'm bilding a BIG huge ass something like 30"x30" x maybe upto 20" Z cnc machine
01:37 AM XXCoder: oh thought it was 2 small ones
01:37 AM _unreal_: no
01:38 AM XXCoder: man my sense of scale is way off
01:38 AM XXCoder: 30"x30" is fairly small for me
01:38 AM XXCoder: once ran a cnc router you could park your car on
01:38 AM _unreal_: this is like https://drive.google.com/open?id=135fMuE3CmP8uoXCki4YfWx3L5kZ-KPTV 20x30" and solid
01:38 AM _unreal_: hum
01:40 AM _unreal_: I'm having 4" square tube mounted on the short sides and the X briges across the long side of the base
01:40 AM _unreal_: the base has NO give to it at all its all I beam and C channel welded
01:40 AM _unreal_: so I'm building a very rigid machine
01:40 AM XXCoder: very strong allright
01:41 AM XXCoder: alum no problem depebding on gantry
01:41 AM _unreal_: I'm thinking I'm going to mount the rail on the top and just have a set of bearings on the bottom
01:42 AM _unreal_: I cant see it flexing
01:43 AM XXCoder: how will you make sure rails is nicely flat and parallel?
01:43 AM XXCoder: and aligned on height too
01:44 AM _unreal_: the rails are going to be mounted with a series of big ass bolts. the holes will be over sized just a hair
01:44 AM _unreal_: err the openings
01:44 AM _unreal_: so the idea is simple
01:45 AM _unreal_: flip the base upside down put it on something very flat. Clamp it down and tighten the bolts
01:47 AM _unreal_: once everything is tight it should be 99% true
01:47 AM XXCoder: you would still need to ensure parallelism
01:48 AM XXCoder: and use block on one side, magnetic base and indictor arm to go over to other side
01:48 AM XXCoder: measure height as block goes across rail its on
01:48 AM _unreal_: hence its at a machine shop so they can face the sides
01:48 AM XXCoder: nice
01:49 AM _unreal_: they are building block inserts
01:49 AM _unreal_: https://drive.google.com/open?id=1n8QM01eo2tG-qUacvH3c_0KZn2RtR0VM
01:49 AM _unreal_: the ends need a filler piece. so they are putting something like 1.5" tick aluminum blocks in
01:50 AM _unreal_: and the aluminum 4" extrusion will bolt to that on the side
01:50 AM _unreal_: through bolting
01:50 AM _unreal_: the underside has I beam construction but its easy to just though bolt
01:52 AM _unreal_: My waste board will float on the ends sadly so I'll prob just get some aluminum angle and bridge it. the 4" square tubing is going to stick out on both ends by like 6"
01:53 AM _unreal_: I dont know that my goal is the best direction but its the one I have chosen
01:53 AM XXCoder: yeah just muddling along lol
01:55 AM _unreal_: my desire is to maximize the work area
01:55 AM _unreal_: so I can fit bigger material in
01:55 AM _unreal_: but its really more so I can do 3d milling
01:57 AM _unreal_: once I have the machine up and running I'll use the machine to mill the parts to make a 2 axis Z
01:57 AM _unreal_: so I'll then have a nice 5 axis machine
02:20 AM CaptHindsight: more better would be a 5 dimensional machine that extends into hyperspace
02:21 AM CaptHindsight: http://haegar.fh-swf.de/spielwiese/unmoeglicheObjekte/english/mathematik4.html

02:51 AM _unreal_: y
02:51 AM _unreal_: sudo update
02:52 AM _unreal_: wtf?
03:01 AM XXCoder: sudo make me sandwinch
03:09 AM Deejay: moin
03:09 AM XXCoder: sudo make me sandwinch
03:22 AM _unreal_: finally finished updating
03:22 AM _unreal_: 500 megs of updates
03:22 AM XXCoder: yay
03:22 AM _unreal_: sigh I should reboot
03:23 AM _unreal_: I guessI'm going to try and go back to bed
03:36 AM JanMrlth is now known as janmar
04:46 AM jthornton: morning
04:47 AM XXCoder: yo
05:12 AM jthornton: well record my desktop sucks, vokoscreen has issues too... gotta find a decent desktop recorder
05:14 AM miss0r: jthornton: facemounted GoPro? :P
05:15 AM jthornton: yea that would suck too lol
05:15 AM XXCoder: i dont know of any good one
05:15 AM XXCoder: last I needed to record, it was quite a while ago and on windows
05:15 AM XXCoder: lol cant even remember name
05:16 AM jthornton: trying simple screen recorder now, it seems to work
05:17 AM XXCoder: nice
05:37 AM jthornton: it's very annoying when something works then for no reason it won't work...
05:40 AM XXCoder: what happened>
05:43 AM jthornton: sometimes I can't select the end point of a line that I added by creating an edge from external geometry
05:43 AM XXCoder: is there a dot?
05:44 AM jthornton: yea
05:44 AM XXCoder: odd should be selectable
05:45 AM jthornton: it's a pain in the ass when you have no clue why it worked before...
06:18 AM Tom_L: morning
06:18 AM XXCoder: yo
06:18 AM XXCoder: figured out why yet?
06:21 AM jthornton: not figured out why it doesn't work sometimes but it just worked this time...
06:30 AM jthornton: weird worked 3 times in a row... dunno what I screwed up before... now to try and capture it
06:31 AM XXCoder: inconsience between drawn and actual position? did it "not work" after you zoomed in or out, or moved it?
07:01 AM _unreal_: kind of like jymmm's electricity ;)
07:01 AM _unreal_: works doesnt work
07:10 AM jthornton: I still don't know why a couple of times I could not select an end point but I've drawn the part 3 times in a row with success so I'm uploading the raw video for now
07:15 AM jthornton: XXCoder, https://www.youtube.com/watch?v=LPF3x5C2Cfw
07:15 AM XXCoder: looking
07:17 AM XXCoder: thats much better way to do cirved part. nice
07:17 AM jthornton: you watched the whole video?
07:17 AM XXCoder: not yet
07:17 AM jthornton: lol I'm still watching
07:18 AM XXCoder: youre extruding now
07:18 AM XXCoder: whats secon sketch for?
07:18 AM jthornton: watch
07:18 AM XXCoder: looked like you copied first "master" lol ok
07:20 AM XXCoder: man youre whole level above me or more lol
07:20 AM XXCoder: effecient
07:20 AM jthornton: I made a few mistakes like not ticking off auto update and that's why it jumped from the big to small
07:22 AM XXCoder: top line tan to curve, and now bottom
07:23 AM XXCoder: what icon caused tan plane to appear?
07:23 AM XXCoder: to right of line and left to "3d corner" icon button
07:23 AM XXCoder: ah! datdum line
07:23 AM XXCoder: *plane
07:24 AM jthornton: well you start with create a datum plane
07:24 AM jthornton: then define the location which I did with the two lines that were tangent to the edge and square to the world
07:25 AM jthornton: I constrained the two lines to the edge of the part so the symmetry constraint would put the hole in the center
07:25 AM XXCoder: interesting!
07:26 AM XXCoder: but is datum plane not center 0,0 on world 0,0 on that side
07:26 AM XXCoder: I notice you used edges to center a hole
07:32 AM jthornton: doesn't seem to be centered notice the origin dot is off center
07:32 AM XXCoder: yeah was wondering
07:32 AM XXCoder: it dont seem aligned to anything at all
07:32 AM XXCoder: ie one of corner of edges, etc
07:35 AM jthornton: I wonder if there is a way to center the datum plane?
07:35 AM XXCoder: good question, might be good short tutorial there too
07:36 AM XXCoder: maybe look around datum data sheet
07:40 AM norias: what software?
07:41 AM XXCoder: freecad
07:41 AM XXCoder: which is free is both respects
07:41 AM XXCoder: *in
07:44 AM norias: ahh, yeah, don't know that one
07:44 AM norias: know of, have used, don't know well enough to answer questions
07:44 AM XXCoder: its gotten quite good in last 2 years
07:44 AM jthornton: ah yea there is a way to align the origin of the datum plane, just need to figure it out
07:45 AM XXCoder: before that any experence dont really matter since some stuff is very different
07:45 AM XXCoder: sketching changed a little just way less crashy
08:00 AM jthornton: less crashy is best
08:00 AM XXCoder: very best
08:19 AM JT-Shop: hmm it's 60°F in the machine shop
08:19 AM XXCoder: nice and cool
08:19 AM XXCoder: i can exercise virtally forever under that condition
08:21 AM JT-Shop: crap webhost4life just charged something to my account... I thought I had all that turned off
08:27 AM XXCoder: maybe they added new service and its default on]
08:28 AM JT-Shop2: 52°F in here
08:35 AM _unreal_: JT-Shop2, 70's here
08:35 AM XXCoder: 95f here
08:36 AM XXCoder: nah kidding, will be 51f
08:36 AM _unreal_: My mistake its 82 just checked
08:36 AM _unreal_: sucks being worm and toasty :)
08:37 AM _unreal_: for me its not really worm its just nice outside
08:37 AM XXCoder: wormy
08:37 AM _unreal_: just go in from the pool side table having breakfast with my munchkin
08:37 AM _unreal_: coffee, bagels, and cream rolls :)
08:37 AM _unreal_: yummy yummy
08:45 AM _unreal_: I wish i could remember what I did with the files for this uC I built
08:48 AM jthornton: XXCoder, I figured out what the issue was, you have to tick off allow external features
08:54 AM Tom_L: nice video jthornton
08:55 AM Tom_L: question
08:55 AM Tom_L: can you do an offset plane from the other end?
08:55 AM Tom_L: to get the same tangent plane
08:56 AM Tom_L: 29°F
09:08 AM _unreal_: ya this sucks I think I've lost my files totally
09:09 AM _unreal_: sucks I was so stupid
09:09 AM _unreal_: this goes back to last week when I put that new memory into the motherboard and it didnt read. and messed up the windows 10 install.
09:10 AM jthornton: what do you mean the other end?
09:10 AM _unreal_: then because I was so tired, i was not thinking straight. and I tried to recover with the win repair crap. only to get to a point where I said fuck it and started to do a win install. they
09:10 AM _unreal_: other end?
09:11 AM jthornton: you can offset from the origin planes
09:11 AM _unreal_: and started to clear the partitions
09:12 AM _unreal_: come to find out @!#$!@#$!@#%3 microsft changed there partition system and instead of making changes and applying them when you hit apply. they happen ON the fly as you make changes
09:12 AM _unreal_: mother fuckers
09:12 AM _unreal_: looks like I'm going to have to redo those cad drawings from scratch
09:12 AM _unreal_: that SUCKS
09:12 AM _unreal_: reallllllllly SUCKS
09:13 AM _unreal_: one of them took a week of adjusting
09:13 AM _unreal_: I'm never saving anything to a windows harddrive again. ALWAYS going to be to a thumb drive or external storage. this forced one drive BS is what it is. BULLSHIT
09:14 AM _unreal_: everything is gone.
09:18 AM Tom_L: XXCoder, you were wondering how this was done: http://tom-itx.no-ip.biz:81/~webpage/cnc/practice_drawings/%2359_shell.jpg
09:18 AM Tom_L: draw the basic flat flange then 2 drawings for the shell and do an extrude
09:19 AM Tom_L: err do a 'shell' command
09:19 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/practice_drawings/%2352_offset_extrude.jpg
09:20 AM Tom_L: on that one you do a rotated plane with an offset extrude. you can offset the starting point of the extrude here
09:21 AM _unreal_: what cha maken?
09:21 AM Tom_L: nothing
09:21 AM Tom_L: those were exercises i did when i took catia
09:21 AM _unreal_: catia?
09:23 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/practice_drawings/Practice_Quiz3.jpg
09:23 AM Tom_L: completely parameter driven
09:24 AM Tom_L: change one value and the whole model updates
09:26 AM _unreal_: Tom_L, are you running windows!!!
09:26 AM Tom_L: yes i run both windows and linux
09:29 AM _unreal_: sigh.. I'm doing a full testdisk scan of the HD see if I can find any deleted files folders
09:29 AM Tom_L: upgraded to buster last night and pooched my lcnc install
09:29 AM Tom_L: need to work on that today sometime
09:30 AM _unreal_: heh
09:30 AM _unreal_: didnt do a backup ehhhh
09:30 AM Tom_L: no, i'm not worried about that
09:30 AM Elmo40: Tom_L, those 2020 roller assemblies look interesting. i'm not a huge fan of running wheels directly on aluminum extrusion, though. it is a soft material after all.
09:31 AM _unreal_: ?
09:31 AM Tom_L: yeah they might be good for something lightweight
09:31 AM _unreal_: Though you where talking to me because I had mentioned setting ball bearings on aluminum
09:32 AM _unreal_: ONLY as strain relief for the main rail system
09:35 AM skunkworks: CaptHindsight: no snow yesterday. It is snowing right now - but not sticking
10:12 AM Tom_L: _unreal_ talk to flyback about disc recovery
10:13 AM burklefoo: Its 48 degrees here now, cold for us tender Californians
10:13 AM cpresser: isnt the fire heating everything up?
10:13 AM Tom_L: i'd say light a fire but that might be a bad idea too
10:14 AM burklefoo: Thats PGEs job
10:14 AM Tom_L: true that
10:17 AM burklefoo: Well its complex, bad priorities at PG and E, Climate change, years of bad forest management (Forests have evolved to burn/recover here) and people who insist on building houses in forests
10:18 AM Tom_L: Elmo40, have the aluminum hard anodized
10:18 AM Tom_L: burklefoo, careless ppl?
10:19 AM burklefoo: That too
10:28 AM _unreal_: I think the files are lost for ever
10:28 AM _unreal_: over written
10:28 AM Tom_L: he's damn good at recovery
10:29 AM _unreal_: I think they have been over written
10:29 AM _unreal_: because the "user" folder is empty
10:29 AM _unreal_: and I just did a testdisk on the drive and it found no delted files
10:29 AM Tom_L: have you looked on a sector level?
10:30 AM _unreal_: ahhh
10:31 AM Tom_L: if i need windows files i generally don't use windows to find them
10:40 AM _unreal_: the only thing I found in the "deleted files" was a bunch of windows files
12:28 PM CaptHindsight: who knew that you could cut through metal?
12:29 PM CaptHindsight: shocking! https://www.washingtonpost.com/national/smugglers-are-sawing-through-new-sections-of-trumps-border-wall/2019/11/01/25bf8ce0-fa72-11e9-ac8c-8eced29ca6ef_story.html
12:30 PM roycroft: how can they be sawing through trumps border wall when not one cm of that wall has been built?
12:30 PM roycroft: all that's been done so far is refurbishment of existing sections of fence/wall
12:31 PM CaptHindsight: more lies :)
12:34 PM CaptHindsight: Vitiello, who helped oversee the development of barrier prototypes in 2017, said the administration could have added better deterrent features if Democrats in Congress had provided more funding.
12:34 PM CaptHindsight: hah
12:37 PM _unreal_: flyback, you live?
02:15 PM Centurion-Dan2 is now known as Centurion_Dan
03:02 PM jymmmm: hola folks!
03:02 PM _unreal_: power's back for the moment I see
03:04 PM jymmmm: It is, but have generator and battery/inverter too
03:04 PM Tom_L: quick! do laundry and change the oil!!
03:04 PM _unreal_: STAT
03:06 PM jymmmm: Tom_L Sadly, I actually DO do the laundry as soon as power is restored. Oil changes are every days on the generator. If the oil needs to be "topped off, I just do an oil change instead"
03:06 PM jymmmm: every 2 days*
03:07 PM Tom_L: good idea
03:07 PM jymmmm: Manual calls for every 20 hours, but every 36 hours seems about perfect. I installed an hour meter on the gen.
03:08 PM _unreal_: hour meter... now your getting serous... nothing like $5 gal of gas for a gen set
03:09 PM jymmmm: Tom_L And the petcock valve seems to be working well so far... https://i.imgur.com/xBOkbi4.jpg
03:09 PM jymmmm: _unreal_: I'm running propane and tapped into the 250Gal tank
03:09 PM jymmmm: So the generator runs non stop for 18 hours a day.
03:09 PM Tom_L: i just wondered if the screws would vibrate loose
03:10 PM jymmmm: Tom_L on the valve itself?
03:10 PM Tom_L: ya
03:10 PM jymmmm: I'm keeping an eye on it, and if so I can use locktight
03:10 PM Tom_L: they're probably pretty tight
03:10 PM _unreal_: ahh
03:11 PM jymmmm: I've already taken the valve apart and retightened them before installing
03:11 PM Tom_L: i gotta replace a furnace blower motor monday
03:11 PM _unreal_: I figured out what is wrong with my generator. the link on the butterfly is broken
03:11 PM jymmmm: Tom_L lovely... not
03:11 PM Tom_L: bushings are wearing enough that it won't start on low speed
03:12 PM _unreal_: non repairable looks like it had a crimped end and the crimp failed
03:12 PM Tom_L: i rewired it for high only just for a couple days
03:12 PM _unreal_: I need to order a new carb for my genset
03:12 PM _unreal_: :/
03:12 PM _unreal_: used it for a week straight when the last hurricain hit here two years ago
03:13 PM jymmmm: Tom_L I have a ceiling fan that lost LOW, only med and high, eh
03:13 PM Tom_L: if i start it with my hand it will go on low
03:13 PM jymmmm: _unreal_: did you drain the carb?
03:13 PM Tom_L: i knew it was going out
03:13 PM jymmmm: Tom_L How about start on high, then turn to low?
03:14 PM Tom_L: naw, doesn't give me the option
03:14 PM jymmmm: bummer
03:14 PM _unreal_: there is a triangle shaped metal part that hooked to the butterfly on the outside of the carb. and the shank that sticks up and is "crimped" to this flat triangle metal piece its more or less failed stripped waht ever
03:14 PM _unreal_: so there is no control of the butterfly
03:14 PM Tom_L: it's older but i keep it because it's made of 'real' metal
03:15 PM _unreal_: I have a 4000 something genset husky or something
03:15 PM jymmmm: Tom_L haha, yep, I get that one
03:16 PM jymmmm: I LOVE (lust?) this dual fuel manual/electric start gen
03:16 PM Tom_L: would be nice but i haven't had to use mine in quite a while
03:16 PM Tom_L: i keep cycling the fuel out of it
03:16 PM Tom_L: and run it every so often and run it dry
03:17 PM jymmmm: Tom_L That's EXACTLY why I wanted dual fuel... no having to store/maintian gas and refilling, etc.
03:17 PM Tom_L: i wish it had an oil filter on it
03:17 PM Tom_L: my mower does
03:17 PM Tom_L: i've had it for over 25 yrs
03:17 PM Tom_L: changed the carb a couple years ago
03:18 PM Tom_L: yeah but everybody knows Ca is gonna be on fire every year
03:19 PM jymmmm: My Honda EU2000i is gas, and I've done a couple mods on. 1 for EASY oil changes, and 2 for "non-stop" operation now, as it has a fuel pump in it
03:19 PM Tom_L: somewhere...
03:20 PM jymmmm: I need to do one more mod and add a switch so it will empty the carb for long term storage.
03:20 PM Tom_L: that's not very big
03:20 PM jymmmm: Nope, and VERY VERY quiet
03:20 PM Tom_L: seems it's advertised as such
03:21 PM jymmmm: can carry with one hand. Will run 8 hours on one gallon at 50% load
03:23 PM Tom_L: so you can run a hair dryer on low for 8 hrs on a gallon
03:23 PM Tom_L: still not bad
03:24 PM jymmmm: and it's inverter, so clean power
03:25 PM jymmmm: Tom_L I did this mod, works GREAT!!!! https://www.youtube.com/watch?v=RDkL593Wbt0
03:35 PM _unreal_: enough dicking/moping around just did up the nc file for the final motor mount for my daughters cnc machine
03:36 PM CaptHindsight: jymmmm: there's always this mod as well https://www.wabashnational.com/images/default-source/product/tank-trailers/dpg/brenner---chemical-tank-trailer-590x415.jpg
03:39 PM CaptHindsight: 8 hours x 7000 gal = 6.4 years of runtime
03:39 PM CaptHindsight: 3.2 years at max load
03:39 PM _unreal_: !! does anyone remember what I did with the PSU for the vacuum?
03:40 PM CaptHindsight: did you check behind the boxes in the back?
03:40 PM CaptHindsight: or under the stuff over there?
03:42 PM _unreal_: twice now...
03:43 PM _unreal_: nope never mind twice and not hard enough
03:44 PM _unreal_: Must have been a bum update.. I just rebooted and now my system is running 10x faster
03:44 PM _unreal_: I know random
03:45 PM jymmmm: CaptHindsight: Need 7 years of stablizer
03:47 PM CaptHindsight: keep it mixing, it won't separate
03:48 PM jymmmm: Tom_L Had put a WANTED ad on craigslist for the generator, one guy was going back to mexico and had to sell everything, so I got the EU2000i for $300. I was VERY fortunate. Even took it to a shop to have it cheacked out and he said it was in great shape.
03:48 PM jymmmm: CaptHindsight: Really? Is that all there really is to stablizer?
03:48 PM CaptHindsight: certainly came in handy for you
03:49 PM CaptHindsight: if the tank is kept still it can separate
03:49 PM CaptHindsight: so this of it as a chemical mixer vs mechanical
03:49 PM CaptHindsight: this/think
03:49 PM jymmmm: CaptHindsight: It has done very well over the years. The NEW dual fuel gen has been fantastic since I did the house electrical (tyvm) and the big 250gal tap
03:50 PM jymmmm: CaptHindsight: Ah, I always thought "stablizer" was to prevent a chemical change
03:50 PM CaptHindsight: how does price of electricity compare on the geny to PG&E?
03:51 PM CaptHindsight: https://en.wikipedia.org/wiki/Phase_separation
03:52 PM CaptHindsight: can occur over temp changes with gasolines
03:52 PM CaptHindsight: https://en.wikipedia.org/wiki/Phase_diagram
03:53 PM jymmmm: CaptHindsight: IDK for sure, but if 50% load runs 8 hours on 5 gal of propane at $2.20/gal... $11 for 1500WH for 8 hours, or $11 for 12KW or $0.92/KW
03:54 PM jymmmm: PG&E is $0.22/KW
03:54 PM CaptHindsight: they claim: fuel stabilizer bonds with gasoline to prevent evaporation
03:54 PM jymmmm: ah ok
03:54 PM CaptHindsight: low vapor pressure solvents are mixed with the gasoline to reduce the rate of its evaporation
03:55 PM jymmmm: CaptHindsight: So, $0.93/kw is better than NO KW's at all
03:56 PM CaptHindsight: this works especially well when you are using a lower density fluid since it also floats to the top and acts as a vapor barrier
03:56 PM CaptHindsight: if the lower density fluid is also of lower vapor pressure
03:57 PM jymmmm: CaptHindsight: I have two 5gal cans. I just pour them in the car, them refill the car and tanks at the station.
03:57 PM _unreal_: damn it no wonder. network cable for the netbook was unplugged
03:57 PM _unreal_: been trying to get the gcode over to it and going wtf
03:57 PM _unreal_: there it is
03:58 PM jymmmm: CaptHindsight: about every six months or so.
03:58 PM CaptHindsight: https://www.eia.gov/dnav/pet/hist/LeafHandler.ashx?n=PET&s=W_EPLLPA_PRS_NUS_DPG&f=W
04:00 PM _unreal_: and milling has started
04:00 PM jymmmm: CaptHindsight: Yeah, it was down do $1.90/gal about 6 weeks ago, price goes up in the fall/winter.
04:02 PM roycroft: are you talking about the price of gasoline, jymmm?
04:02 PM jymmmm: roycroft: propane generator
04:02 PM roycroft: oh, ok
04:02 PM roycroft: that sounds like a reasonable price for propane
04:02 PM jymmmm: well, dual fuel, but I have tapped into the big 250/gal propane tank
04:03 PM roycroft: i was going to say - gasoline is $3.79 here, and it's always at least $0.50 more in california
04:04 PM jymmmm: roycroft: It's saved us from throwing out spoiled food, kept the lights, internet and tv going. I'm VERY HAPY and fortunate to have it
04:04 PM roycroft: yup
04:04 PM roycroft: a generator is a great thing to have
04:04 PM roycroft: and i have no confidence that pg&e will ever get caught up in maintenance
04:04 PM jymmmm: roycroft: and I have the Honda EU2000i (gas) as a backup too.
04:05 PM roycroft: i anticipate that the state or the city of san francisco will end up taking them over and turning it into a public utility
04:05 PM roycroft: in which case it will take at least 5-10 years before they develop a good plan to fix everything
04:05 PM roycroft: and then another 10 years to implement it
04:05 PM roycroft: but that's still faster than pg&e would do it as a private corporation
04:06 PM roycroft: so you're gonna have this problem basically for a generation, no matter what
04:06 PM CaptHindsight: whos fault was that? Are we blaming the Mexicans, greed, act of god or what?
04:06 PM roycroft: i vote for greed
04:06 PM jymmmm: CaptHindsight: PG&E for not doing maintance 10 years ago
04:06 PM roycroft: because that's the truth, borne out by the facts
04:06 PM roycroft: pg&e decided to line their shareholders' pockets in lieu of doing maintenance
04:07 PM CaptHindsight: who was watching the hen house?
04:07 PM roycroft: they've run themselves into the ground
04:07 PM roycroft: there's the real problem
04:07 PM CaptHindsight: self regulation?!
04:07 PM roycroft: utilities are largely self-policing
04:07 PM CaptHindsight: huh, whodah thought that was a bad idea?
04:07 PM roycroft: but we can blame obama if that makes people feel better :)
04:08 PM CaptHindsight: ok
04:08 PM roycroft: i mean, he had the gall to continue presidenting while things over which he had no control continued to happen
04:08 PM CaptHindsight: how dare he!
04:09 PM roycroft: but in seriousness, this isn't even entirely the fault of pg&e
04:10 PM roycroft: sure, they neglected maintenance, and that's the immediate cause of most of the fires (notably, the getty fire was started by a transmission line owned by the los angeles public power utility)
04:10 PM CaptHindsight: corruption, it's like we can't figure out how to stop it
04:10 PM CaptHindsight: it's like whack a mole
04:10 PM roycroft: but forest mismangement for the better part of a century is what set things up to be so bad
04:10 PM CaptHindsight: like trees growing
04:10 PM CaptHindsight: and power line poles don't
04:11 PM roycroft: and again, in defense of folks responsbile for forest management, it's not until the 1970s that we really understood how to properly manage forests
04:11 PM SpeedEvil: CaptHindsight: we need power poles that grow
04:11 PM roycroft: without the data to prove otherwise, it intuitively seems that suppressing all fires is the best way to manage a forest
04:11 PM roycroft: but we have the data now that shows otherwise
04:11 PM CaptHindsight: or like building communities in places that burn...
04:11 PM CaptHindsight: low on resources like water, power etc
04:11 PM SpeedEvil: Only you can prevent natural ecosystem turnover and major fire risk reduction.
04:11 PM roycroft: it's not a simple problem to solve
04:12 PM roycroft: and just blaming one entity for causing it does absolutely nothing to solve it
04:12 PM CaptHindsight: like living on a fault line and complaining about the ground shaking
04:12 PM roycroft: that all said, pg&e knew what they needed to do
04:12 PM roycroft: we have been managing our forests better
04:12 PM CaptHindsight: or on a sinking beach
04:13 PM roycroft: it's reasonable to hold pg&e largely responsible
04:13 PM CaptHindsight: noisy airport and complaining about noise
04:13 PM roycroft: and given that they're doing *nothing* real that will ameliorate the problem, they deserve whatever they get at this point
04:13 PM CaptHindsight: but profit!
04:14 PM SpeedEvil: My ducats!
04:14 PM CaptHindsight: what do you have against profit? Are you some kinnah commie?
04:14 PM CaptHindsight: no that can't be true since China loves profit
04:15 PM roycroft: there is nothing wrong with profit
04:15 PM CaptHindsight: same for mother Russia
04:15 PM jymmmm: Thorium reactors FTW
04:15 PM roycroft: but excessive profit at the cost of social responsibility is a problem
04:15 PM CaptHindsight: gimmie!
04:15 PM jymmmm: Hey lawrence
04:15 PM CaptHindsight: but how do you teach a sociopath about social responsibility?
04:15 PM roycroft: the first thing that should be done is this:
04:16 PM roycroft: whenever pg&e decide they need to impose a massive power outage
04:16 PM roycroft: before they turn off the power to the other ratepayers, they should be required to turn off the power to all company execs and all company board members
04:16 PM roycroft: and not allow any of those people to use generators
04:16 PM CaptHindsight: I agree
04:17 PM roycroft: and they execs and board members cannot have their power restored until after everyone else's power is restored
04:17 PM roycroft: that would be a good start :)
04:17 PM CaptHindsight: but then you won't have a double standard
04:18 PM _unreal_: how dare you
04:18 PM CaptHindsight: it was what uhmerica was built on
04:18 PM roycroft: one standard to rule them all
04:18 PM roycroft: one standard to bind them
04:18 PM jymmmm: CaptHindsight: https://www.extremetech.com/extreme/254692-new-molten-salt-thorium-reactor-first-time-decades
04:18 PM CaptHindsight: you see, you have to be more important, then the same rules do not apply to you
04:19 PM jymmmm: CaptHindsight: https://en.wikipedia.org/wiki/Mojave_Solar_Project 250KW BABY!!!!!!
04:19 PM CaptHindsight: important or wealthier, much more wealthy
04:19 PM jymmmm: MW*
04:20 PM CaptHindsight: https://www.thechemicalengineer.com/news/milestone-for-molten-salt-nuclear-reactors/
04:21 PM CaptHindsight: jymmmm: you see the oil industry does not benefit from renewable energy sources
04:21 PM CaptHindsight: so we can't do that
04:22 PM SpeedEvil: jymmmm: I note: The power plant cost an estimated $1.6 billion in total and entered commercial operation in December 2014
04:23 PM SpeedEvil: And I further note that solar-PV is now at well under $0.5/W.
04:23 PM SpeedEvil: I leave the division as an exercise for the reader.
04:23 PM CaptHindsight: united we stand
04:24 PM CaptHindsight: invisible, with liberty and justice for some
04:25 PM CaptHindsight: http://www.ushistory.org/documents/pledge.htm
04:25 PM CaptHindsight: SpeedEvil: we have this pledge thing here they make all the school kids repeat every day before class
04:26 PM CaptHindsight: some people are just more equal than others
04:26 PM drdoc: yowsa
04:26 PM SpeedEvil: https://i.imgur.com/Je0IpMs.jpg
04:26 PM CaptHindsight: SpeedEvil: is solar catching on in the UK?
04:27 PM SpeedEvil: CaptHindsight: Current government is being fuckheaded about it.
04:27 PM drdoc: "mango pickle" is apparently code for "a little oil, a dab of mango puree, and a lot of radioactive chillies"
04:27 PM SpeedEvil: They slashed the current scheme - which would have been fair enough - net metering is actually reasonable with UK electricity prices.
04:28 PM SpeedEvil: CaptHindsight: but they left the current regulations on installing panels in place - which were to prevent abuse.
04:29 PM CaptHindsight: SpeedEvil: don't you have the worlds highest output wind farm off the coast of Scotland?
04:29 PM SpeedEvil: If I could 'net meter' (it's not net metering, it's considerably below nominal electricity price) without those regulations in place, I could easily (in scotland) make a significant profit just buying ~20kW of low-end panels and sticking them on the grid
04:30 PM SpeedEvil: Payback of the panels in ~2 years.
04:30 PM CaptHindsight: how dare you try to be an energy supplier!
04:30 PM SpeedEvil: Or ~4 if I use the nice panels.
04:31 PM CaptHindsight: SpeedEvil: where are the panels produced?
04:31 PM SpeedEvil: https://www.bimblesolar.com/solar/solar-pallets/ja265w-pallet
04:32 PM SpeedEvil: I would assume china
04:32 PM drdoc: CaptHindsight: you're in Texas, right?
04:32 PM CaptHindsight: IL/WI border
04:32 PM drdoc: Ah
04:32 PM drdoc: Somebody here's in TX....
04:32 PM drdoc: ;-)
04:33 PM drdoc: I heard on the radio yesterday that Texas generates more electricity with windmills than with coal
04:33 PM CaptHindsight: I had a friend that passed away who was from Texas...
04:33 PM SpeedEvil: CaptHindsight: https://octopus.energy/outgoing/
04:34 PM drdoc: ...and there's a strong faction in central Texas that wants to eliminate or severely limit them
04:34 PM SpeedEvil: CaptHindsight: the regulations that are in place on the solar panel installations come from a time when the price paid per kWh of solar was 2* sometimes the retail electricity price, and they're unfit for a time when it's 0.5*, as they impose massive regulations.
04:34 PM drdoc: They kills the birds, dontcha see?
04:35 PM CaptHindsight: https://energynews.us/digests/nearly-a-third-of-u-s-wind-energy-capacity-is-in-texas/
04:36 PM CaptHindsight: Wind power in Texas consists of many wind farms with a total installed nameplate capacity of 25,629 MW[1][2] from over 40 different projects. If Texas were a country, it would rank fifth in the world
04:36 PM drdoc: going west on US 84, between Snyder & Justiceburg, is a beautiful sight
04:36 PM CaptHindsight: https://en.wikipedia.org/wiki/Wind_power_in_Texas
04:36 PM _unreal_: ok part milled
04:36 PM drdoc: It's like a scene out of War Of The Worlds
04:36 PM drdoc: :-)
04:36 PM _unreal_: NOW I have to go to the hardware store to get some threaded rod again
04:37 PM CaptHindsight: windmills kills birds, coal and oil power kills everything
04:37 PM drdoc: rank upon rank upon rank of windmills, literally out to the horizon
04:37 PM _unreal_: I'm all out and I need like 16" for the stand offs for the steppers
04:37 PM _unreal_: the last stepper
04:37 PM drdoc: CaptHindsight: it's fucking ridiculous and criminal
04:37 PM drdoc: trying to limit windmills, I mean
04:38 PM CaptHindsight: https://s.hdnux.com/photos/74/40/73/15863528/5/920x920.jpg
04:38 PM CaptHindsight: yes
04:38 PM SpeedEvil: A modern day sancho panza.
04:38 PM _unreal_: CaptHindsight, the smallest ACTIVE volcano on earth puts out more "planet killing" gasses then any 3 coal elec plants
04:38 PM CaptHindsight: the selfish
04:38 PM drdoc: yeah, imagine that photo going on for 10-15 miles
04:38 PM SpeedEvil: There are a hell of a lot more than 3 coal plants
04:39 PM CaptHindsight: SpeedEvil: no lets hear this logic :)
04:39 PM CaptHindsight: I need a good laugh
04:39 PM _unreal_: lol the earth prodces 94% of the OZ killing gasses humans produce 6% as of the statistics from I believe 10 years ago
04:40 PM CaptHindsight: and my cars output doesn't kill anyone
04:40 PM _unreal_: and the US has gone way more green since then 90% more then any other MAJOR industrial cuntrey
04:40 PM _unreal_: county
04:40 PM CaptHindsight: and the trash I throw out on the road doesn't litter up anyone
04:40 PM _unreal_: SIGH I need two 1.25" 1/4-20's
04:41 PM _unreal_: as well
04:41 PM _unreal_: when I have those 3 items I can get the last motor mounted on my daughters CN
04:41 PM _unreal_: CNC
04:41 PM _unreal_: so close
04:42 PM drdoc: I have already identified this Optiplex 980's bottleneck
04:42 PM CaptHindsight: drdoc: what is that?
04:42 PM drdoc: the installation is going slower than it did on my D510 box
04:42 PM _unreal_: optiplex...? god I know that... sigh google
04:42 PM drdoc: the disk sounds like a roulette wheel
04:43 PM _unreal_: not what I thought it was
04:43 PM _unreal_: drdoc, I thought that was a scsi card
04:43 PM drdoc: heh
04:44 PM CaptHindsight: SpeedEvil: see it's not anyone fault, sunspots, volcanoes, mexicans are just natural cycles the Earth goes through
04:44 PM drdoc: I'll be throwing an SSD in there if the latency looks good
04:45 PM CaptHindsight: SpeedEvil: and since I'll be dead it won't effect me much
04:45 PM drdoc: can't bitch about a freebie, though
04:46 PM * drdoc paints CaptHindsight's face orange and dyes his hair yellow
04:47 PM _abc_: Hi. Anyone tried to port this to linuxcnc? https://github.com/ratmole/Mach3Pendant
04:49 PM _unreal_: whats a pendant?
04:49 PM _unreal_: _abc_,
04:49 PM CaptHindsight: it's good to be the Great Pumpkin
04:49 PM _abc_: _unreal_: that is an unreal question.
04:50 PM _unreal_: ok charlie brown
04:50 PM _unreal_: Though I'd get a reaction _abc_
04:51 PM _unreal_: _abc_, thats for mach3 not lcnc
04:51 PM _abc_: Thus "porting"
04:51 PM _unreal_: would be nice to have a "pendent" like that for lcnc
04:51 PM CaptHindsight: _unreal_: https://en.wikipedia.org/wiki/Role-playing
04:52 PM _unreal_: maybe thumb intensity control as well by sliding the finger from center to an Axis or mixing axis's
04:52 PM CaptHindsight: pendant on a smartphone!
04:53 PM CaptHindsight: you can get a whole GUI on there!
04:53 PM CaptHindsight: so you CAN machine while at the beach
04:53 PM _abc_: I's a better idea not to. You can use VNCview app on phone to get the whole gui
04:53 PM _unreal_: I've always thought it would cool to have a hybrid pendent that has an embeded phone as the HID
04:53 PM _abc_: I'd prefer a responsive pendant when doing the zeroing by hand etc
04:54 PM XXCoder: Tom_L: interesting :)
04:54 PM CaptHindsight: better yet, get somebody else to run the machine while you are out
04:54 PM _abc_: I am not an octopus to reach the keyboard with the left toe emacs style while holding the calipers and the jig in the 2 hands.
04:54 PM XXCoder: _unreal_: thats why I backup system :(
04:54 PM _abc_: Alternate jogging unit: 4-way pedal on floor.
04:55 PM _unreal_: _abc_, I'm talking about a hybrid with an encoder wheel and a phone as the HID plus estop etc....
04:55 PM _unreal_: XXCoder, ?
04:55 PM _abc_: You really do not want to rely on the estop on the phone
04:55 PM _unreal_: _abc_, read!!!
04:56 PM _unreal_: + estop, YOU KNOW BIG shiny pull out button
04:56 PM XXCoder: you said you wiped install
04:56 PM XXCoder: I had raid system 2 disk fail on me at same time. if I didnt have backup I'd have lost everything
04:57 PM _unreal_: XXCoder, I lost my files thanks to microcrap changing there partitioning software
04:57 PM _unreal_: use to be you made changes and hit COMMIT
04:57 PM _unreal_: now its on the fly and does not worn you
04:57 PM XXCoder: yeah backup would help you recover from that
04:58 PM _unreal_: only 3 freaking files I needed
04:58 PM _unreal_: I already did a full hd scan sector scan.....
04:58 PM _unreal_: there gone
04:58 PM _unreal_: over written
04:58 PM _unreal_: I get to do them again
04:58 PM _unreal_: I'm just not saving anything to winblows HD any more ever
04:59 PM _unreal_: if its cad files
04:59 PM XXCoder: and have good backup system
04:59 PM XXCoder: buy huge portable drive
04:59 PM _unreal_: I have tons of drives
04:59 PM _unreal_: I'm just lazy
04:59 PM _unreal_: :)
04:59 PM _unreal_: saddly I have a huge tower next to me with 21 HD in it
04:59 PM _unreal_: I have not powered it in years
05:00 PM _unreal_: all the content is old. non of the hardware is in it anymore except maybe the original HD https://www.overclockers.com/berins-case-mods/
05:01 PM XXCoder: lol ok
05:02 PM _unreal_: I still have the radiator. I still have never used it to this day. I'm going to use it for the new cnc machine that I'm building. I'll use it as the coolent chiller
05:03 PM _unreal_: I'll just do a small closed loop setup :) water pump, spindle, radiator+fan and back :)
05:05 PM _unreal_: I have modified the case further from the photos. now there is a 3rd tier of HD mounts at the very bottom. and an other on the left bottom side over the twin fans.
05:05 PM _unreal_: there is an other HD mount above the PSU
05:06 PM _unreal_: and its loaded with old HD's I have no idea whats on them
05:10 PM jymmmm: If you have a Honda EU2000i, this tri-fuel kit is pretty cool $260... https://www.hutchmountain.com/
05:13 PM jthornton: jymmmm, we made that chicken recipe the other day it was pretty good
05:19 PM CaptHindsight: jymmmm: what is the best way to spread a damp layer of sand 0.01" thick over an area 1ft x 2ft?
05:21 PM CaptHindsight: angled knife blade?
05:22 PM CaptHindsight: https://www.youtube.com/watch?v=-DvYG7vN2sg
05:22 PM CaptHindsight: ^^ possibly for much large areas
05:24 PM _unreal_: CaptHindsight, what are you trying to do
05:25 PM CaptHindsight: _unreal_: spread even 0.01" thick layers of sand one on top of another
05:25 PM CaptHindsight: in a box
05:25 PM CaptHindsight: ~ 1ft x 2ft
05:25 PM CaptHindsight: or ~2ft x 2ft
05:26 PM jymmmm: CaptHindsight: two 0.01" thick rods and a 2x4
05:26 PM jymmmm: jthornton: the honey butter recipe?
05:26 PM CaptHindsight: the sand is slightly damp, not dry, so it's a bit more complicated than just spreading sand from a bin
05:27 PM jymmmm: jthornton: I want to try it with pork. Glad you liked it, super easy =)
05:28 PM jymmmm: CaptHindsight: use two rods the thickness you want, then the 2x4 to spread out the sand
05:28 PM _unreal_: CaptHindsight, there are a number of ways to do it
05:28 PM _unreal_: but what is the finish result?
05:28 PM jymmmm: CaptHindsight: just run the 2x4 across the rods
05:28 PM CaptHindsight: jymmmm: this should be automated and there might be several thousand layers 0.01" thick
05:28 PM _unreal_: are you using a resin to hold the sand like a nonskid?
05:29 PM jthornton: yea the honey butter one, takes like 15 minutes, we prefer rice cooked in a 100 year old pot from Puerto Rico
05:29 PM _unreal_: CaptHindsight, you have two options
05:29 PM jymmmm: jthornton: niiice =) Yeah, and they weren't kidding about no cooking more than 7 minutes
05:30 PM _unreal_: use a large screen box and put the sand in it, and shake the shit out of it
05:30 PM jymmmm: CaptHindsight: cnc squeegy
05:30 PM _unreal_: or have an off balance motor on it to do the shaking for you
05:30 PM _unreal_: the other option is to use a small sand blaster
05:30 PM CaptHindsight: dry powder is easy https://youtu.be/kBHsfNDsbCs?t=29
05:30 PM _unreal_: those are the only easy evey ways to apply
05:31 PM CaptHindsight: new layers should be applied in 1 second or less
05:32 PM jymmmm: jthornton: honey + pork seem like it might be better, I'm going to try that next
05:32 PM _unreal_: bbib going to the hardware store to pick up some 10-24 threaded rod to mount the motor
05:37 PM Tom_L: evening andy
05:46 PM Deejay: gn8
05:48 PM andypugh: Hi
05:50 PM CaptHindsight: andypugh: did you get the laterer news on RTAI?
05:50 PM andypugh: Yes, but I am busy this weekend with other things.
05:51 PM CaptHindsight: no rush
05:51 PM CaptHindsight: just passing it along
05:53 PM CaptHindsight: andypugh: unless someone finds bugs that is it for RTAI development for a while, well at least the holidays coming up
05:54 PM CaptHindsight: i think the only issue might be intel graphics support in the kernel config
05:54 PM CaptHindsight: some Intel users say they are limited to 1028 x 768
05:56 PM CaptHindsight: https://forum.linuxcnc.org/9-installing-linuxcnc/37106-testers-needed-for-new-rtai-packages?start=30
05:57 PM CaptHindsight: "hail and farewell"
05:57 PM flyback: _unreal_, ?
05:57 PM flyback: \what did you need?
05:59 PM Tom_L: he lost some files on a windows disk
05:59 PM Tom_L: i told him you knew where they were...
06:02 PM flyback: yeah mabye I can help
06:03 PM flyback: first thing is to shutdown the box and *NOT* use it
06:05 PM Tom_L: probably too late for that
06:28 PM flyback: well he seems to have wandered off
06:28 PM flyback: if he comes back in the next few hrs I should be around to help
07:05 PM sync: CaptHindsight: what's the usecase for rtai nowadays? I don't really see any benefit over preempt rt
07:06 PM Tom_L: works better on older hardware
07:06 PM _unreal_: flyback, prob to late
07:07 PM _unreal_: trying to recover some files I lost but I'm 99% sure they are gone
07:08 PM sync: Tom_L: yes, but you can just buy new hardware
07:08 PM _unreal_: I didnt wonder I knew exactly where I was
07:08 PM Tom_L: unless someone is on a real budget
07:08 PM _unreal_: I just got a 50ct
07:09 PM _unreal_: Toshiba Libretto 50ct
07:09 PM sync: even on a tight budget you can pull a relatively modern computer out of the scrap
07:09 PM _unreal_: dont know if it works or not got to find a PSU and test it.
07:09 PM _unreal_: payed $40 @#$R@#$ for it, god goodwill is such a rip off
07:10 PM _unreal_: and no psu with it
07:11 PM * _unreal_ is gitty if it works
07:46 PM CaptHindsight: sync: how would you like me to answer that question?
07:46 PM XXCoder: fuck goodwll
07:46 PM CaptHindsight: RTAI has lower latency than preempt_rt and Xenomai on most hardware
07:46 PM skunkworks: sync: usually it has better latency....
07:47 PM CaptHindsight: if you can't see the difference then it does not matter to you
07:47 PM XXCoder: flyback: yeah entire os was installed over it. its gone good chance.
07:47 PM skunkworks: CaptHindsight: get any accumulations?
07:48 PM XXCoder: partition being "live" (ie instantly being performed as selected) is new and worrying
07:48 PM CaptHindsight: https://forum.linuxcnc.org/9-installing-linuxcnc/37106-testers-needed-for-new-rtai-packages?start=30
07:48 PM XXCoder: *partition management on windows install
07:48 PM CaptHindsight: this thread on the forums has some users results for RTAI vs prempt_rt
07:49 PM CaptHindsight: we (me and the RTAI developer) always get lower numbers with RTAI
07:51 PM skunkworks: My hope is rt_preemt will get better and better as there are more eyes on it.
07:51 PM flyback: na it's possibly not gone
07:51 PM flyback: I have recovered all kinds of shit
07:52 PM skunkworks: Photorec!
07:52 PM CaptHindsight: we shipped some Intel Celeron 847 systems with preempt_rt before the new RTAI was ready and the numbers were ~20,000, so it didn't matter
07:52 PM CaptHindsight: skunkworks: well RTAI.org pushes out new unstable versions
07:53 PM skunkworks: CaptHindsight: yes - but it is you guys that make it work.. that must suck
07:53 PM CaptHindsight: https://github.com/NTULINUX/RTAI he fixes it
07:54 PM CaptHindsight: skunkworks: it's weird, up until now the Linuxcnc distributions would use some combo of the two
07:54 PM flyback: _unreal_, how big is the drive
07:55 PM sync: CaptHindsight: yes, but the latencies are low enough using preempt rt to just pump data out of the ethernet port
07:55 PM CaptHindsight: I think Andy is planning on using the https://github.com/NTULINUX/RTAI/tree/new-libm
07:55 PM skunkworks: CaptHindsight: that is your son - right?
07:55 PM CaptHindsight: yeah
07:55 PM skunkworks: I think I may have met him at one of the fests..
07:56 PM CaptHindsight: sync: not everyone is using Ethernet FPGA's
07:56 PM CaptHindsight: some are using FPGA's and still need lowest possible latency
07:56 PM skunkworks: If you are bit banging - rtai still is the king
07:56 PM CaptHindsight: skunkworks: I was at Wichita, he stayed home
07:57 PM skunkworks: oh - maybe that was it
07:58 PM CaptHindsight: but now he's going to be busy so RTAI will be on pause for a while
07:58 PM skunkworks: are you a slave driver? Huh? ;)
07:59 PM CaptHindsight: he has to fix someones real time embedded distro
07:59 PM CaptHindsight: most of my stuff is hardware
07:59 PM CaptHindsight: I'm working on the GUI and LCNC support for DLP/LCD printing
08:00 PM skunkworks: cool
08:00 PM skunkworks: we still are limping along the DTS - (digital to screen)
08:00 PM skunkworks: (uses a dlp to expose the silk screen
08:00 PM CaptHindsight: https://imgur.com/zvxoHUT
08:01 PM CaptHindsight: yeah works similar
08:01 PM CaptHindsight: and we are also doing it with sand for sand molds/casting
08:02 PM CaptHindsight: https://imgur.com/zKNtBAg
08:03 PM CaptHindsight: skunkworks: so instead of the silkscreen, we expose the sand and resin to the light
08:03 PM CaptHindsight: curing only the mold
08:03 PM CaptHindsight: the rest of the sand wipes/brushes away
08:04 PM skunkworks: Cool
08:04 PM CaptHindsight: cheap play sand has ~300um res. https://imgur.com/IvelAIb
08:04 PM sync: CaptHindsight: I don't see a reason why you would use anything but something that is connected through ethernet
08:04 PM skunkworks: pci is much faster...
08:04 PM CaptHindsight: sync: I use PCIe most often
08:05 PM CaptHindsight: to LPT or FPGA
08:05 PM sync: yes, pcie is another option, but I don't see the need as the bandwidth you need is quite low
08:06 PM CaptHindsight: skunkworks: he's off to work for a giant medical imaging co
08:07 PM CaptHindsight: they don't even blink an eye at spending $1Million on a Linux distro that doesn't work
08:07 PM CaptHindsight: at least not for them
08:08 PM CaptHindsight: I told him to build a gentoo ISOa dn show that it works and then offer to split the difference in the savings :)
08:08 PM CaptHindsight: a dn/and
08:09 PM CaptHindsight: I'm sure politics won't let that happen
08:10 PM flyback: lpc lpt should be possible
08:10 PM XXCoder: https://www.windows93.net lol
08:11 PM CaptHindsight: sync: sometimes I have IO that needs to generate an interrupt as fast as possible
08:12 PM CaptHindsight: some external event that is synched to motion
08:12 PM CaptHindsight: https://imgur.com/LOriL1y 5-axis inkjet
08:12 PM skunkworks: and ethernet adds to the latency
08:13 PM CaptHindsight: yes uS vs mS
08:13 PM skunkworks: so your round trip is closer to 500ms instead of 10us with pci
08:13 PM skunkworks: soory
08:13 PM skunkworks: .5ms
08:13 PM skunkworks: ok - on good hardware it might be closer to .1ms
08:14 PM sync: I have not seen such large rtts with ethernet and a directly attached device
08:14 PM sync: yeah, but you can just tell your drive to generate an event at a certain position
08:14 PM CaptHindsight: inkjet is crazy high bandwidth, or can be
08:15 PM CaptHindsight: K's of nozzles, each firing at 50Khz
08:15 PM sync: yes, that's an application where pcie is a good choice depending on the setup
08:19 PM CaptHindsight: seems like finding Linux development jobs is tough
08:20 PM CaptHindsight: they say Linux developer but they mean "some graphical config tool user" to integrate with "cloud services"
08:20 PM CaptHindsight: more Linux user/configurerer
08:22 PM burklefoo: Capthindsight: I do have a working XY2-100 driver now if you have a way to test it (it allows setting position, velocity and acceleration so can move smoothly between waypoints )
08:22 PM CaptHindsight: or GUI web developer
08:22 PM CaptHindsight: burklefoo: for the Mesa cards or?
08:22 PM burklefoo: Yes, Mesa
08:23 PM CaptHindsight: pcw_mesa: was mentioning something similar
08:23 PM burklefoo: Thats me somehow I got assigned my alternate name
08:23 PM CaptHindsight: you can get a cheap set of XY2-100 galvos for <$100
08:23 PM CaptHindsight: OK, :) didn't know
08:24 PM CaptHindsight: I've been using the analog servos until now
08:24 PM burklefoo: can you give me a pointer, all the ones I say were ~$500ish
08:24 PM burklefoo: I saw
08:24 PM CaptHindsight: burklefoo: how do I test? hold on...
08:25 PM CaptHindsight: https://sino-galvo.en.alibaba.com/?spm=a2700.details.cordpanyb.4.31c06543xTplJY
08:25 PM CaptHindsight: they are also on ebay
08:27 PM burklefoo: Industrial or "Medical Beauty" :-)
08:32 PM CaptHindsight: https://www.ebay.com/itm/Dynamark-Sator-Laser-Co2-Laser-Scan-Head-for-Synrad-or-Coherent/173332218244 US $225.00
08:34 PM CaptHindsight: there were others
08:34 PM burklefoo: Thats not bad though I would prefer something that worked with visible light for testing
08:35 PM CaptHindsight: I'll send you links when I have time
08:35 PM CaptHindsight: swap the lens
08:36 PM CaptHindsight: 10mm mirrors so 5mm beam at input max
08:37 PM CaptHindsight: likely silver mirrors so you could swap the f-theta lens for a visible spectrum lens vs IR
08:37 PM burklefoo: I'll look also when I get a chance, need to verify the offset binary and parity stuff, I did get the velocity and accel scaling right finally
08:37 PM CaptHindsight: let me check around here for leftover stuff as well
08:39 PM burklefoo: so the hal pins are position, velocity and accel for X and Y, postion overflow and vel overflow flags (both are bounded) plus the 3 control bits for X and Y and the status return bit
08:40 PM burklefoo: when i get the driver for the DataPainter module done it would be a good matching video channel
08:41 PM burklefoo: though I need help with the required new hal type for array data
08:42 PM CaptHindsight: I'd like to make a nice LCNC GUI for that as well
08:42 PM CaptHindsight: one for SLA or SLS printing
08:42 PM CaptHindsight: and one for laser marking and cutting
08:43 PM CaptHindsight: knowing that it is so close maybe i can demo a large printer using the analog controller and get this funded
08:44 PM burklefoo: currently these no special handling for the fact that its an absolute output device, Would a pins for Xscale/YScale be better than a parameter?
08:44 PM CaptHindsight: somebody already wants a big bed sand mold printer
08:44 PM burklefoo: (pins would allow dynamic scaling)
08:44 PM CaptHindsight: 5m x 5m
08:44 PM CaptHindsight: sure
08:45 PM burklefoo: currently scaling is done with parameters, but that should be OK for a test
08:46 PM CaptHindsight: the scan area is limited by the max movement of the mirrors and the f-theta lens focal length
08:47 PM CaptHindsight: then you work backwards from there for the analog version of this
08:47 PM burklefoo: scaling of 1 currently means +-32767 for full scale
08:47 PM burklefoo: so scaled in bits
08:47 PM CaptHindsight: say i have a max on Y of 5V on a +-5V galvo
08:48 PM CaptHindsight: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=6430
08:48 PM CaptHindsight: 100mm lens gets you a 70 x 70mm scan area
08:49 PM burklefoo: Ahh that's how they get a flat field
08:50 PM sync: yes, ftheta lenses are a nice hack
08:50 PM CaptHindsight: I guess if I had digital scaling it might be an easy way to change the field size without changing optics or the position of the scan head
08:51 PM CaptHindsight: with trading off some precision
08:51 PM sync: I wonder how difficult it would be to make a driver for galvos, the optical feedback seems quite straight forward
08:51 PM CaptHindsight: it's not
08:51 PM CaptHindsight: if you like analog amplifiers
08:52 PM CaptHindsight: the galvos are always on
08:53 PM CaptHindsight: like a servo in position mode, pushing back and forth
08:53 PM CaptHindsight: the amps also correct for non-linearity
08:53 PM burklefoo: Do they actually have feedback? ( I can imagine auto calibration or full feedback with a beamsplitter and a linear array sensor )
08:54 PM sync: yes they do
08:54 PM sync: most of them have two or four photodiodes and a plate on the back of the rotor
08:54 PM CaptHindsight: i don't feedback to the 7i77, it's open loop servo
08:54 PM sync: and you just look at the intensity to get the angle
08:55 PM sync: well, your feedback is intensity and a sine
08:55 PM sync: so you can just do closed loop control to that
08:56 PM sync: the current bandwidth you need will be relatively high but I don't see why it should be a major pain
08:56 PM CaptHindsight: I just buy matched mirrors, motors and and amps
08:56 PM burklefoo: In any case I will take a look for XY2-100 scanners on Ebay in case a more likely subject appears
08:57 PM burklefoo: (I will just use a little diode laser to check)
08:57 PM CaptHindsight: i have a 405nm scan head here with XY2-100 but no specs or pinouts
08:57 PM CaptHindsight: was too old for them to send me the pinouts and specs
08:58 PM CaptHindsight: is like IBM with specs https://www.cambridgetechnology.com/products/galvanometer-scanner
08:58 PM CaptHindsight: when it's old they no longer do anything to support you
08:59 PM CaptHindsight: Small Angle Step Response (Typical) 100 μs - 200 μs
08:59 PM CaptHindsight: burklefoo: what is the bandwidth of the XY2-100 you have?
09:01 PM sync: hmm, that is actually quite slow
09:01 PM CaptHindsight: Scan Angle ± 20°
09:01 PM sync: CaptHindsight: I would probably not do an analog amp
09:01 PM burklefoo: Its not buffered so depends on you servo thread rate, _but_ since it has acceleration, it can do parabolic interpolation between position waypoints
09:02 PM CaptHindsight: the 10mm mirror versions draw around 5A max per motor
09:02 PM burklefoo: (normal XY2-100 repeats the digital data at a 100 KHz rate = 2MHz shift clock)
09:03 PM sync: yeah 5-10A seems common
09:04 PM sync: that's not a lot tho
09:04 PM CaptHindsight: Sino in Beijing makes decent low cost heads
09:04 PM CaptHindsight: for now
09:04 PM CaptHindsight: i pay 2-3X for uhmerican brands
09:10 PM CaptHindsight: https://precisionlaserscanning.com/2016/03/galvanometer-scanners-not-fast-enough-for-your-new-laser-or-application/
09:10 PM sync: yeah they seem to be quite cheap, I guess I need to get me one and have a go
09:11 PM CaptHindsight: the problem is patents on the use of polygon scanners
09:11 PM CaptHindsight: in laser printers it's expired
09:11 PM CaptHindsight: as a 3d printer its suddenly new
09:12 PM sync: I guess you could use two polygons even
09:12 PM CaptHindsight: yes XY
09:13 PM CaptHindsight: https://www.youtube.com/watch?v=0_JrApuTGEA
09:13 PM CaptHindsight: was using these in the 1980's for laser positioning
09:15 PM CaptHindsight: https://precisionlaserscanning.com/polygon-scanners/
09:15 PM CaptHindsight: https://www.youtube.com/watch?time_continue=1&v=enzEDkyKssE
09:16 PM sync: one of the polygons would need to be quite big
09:16 PM sync: but that should not be an issue
09:16 PM CaptHindsight: depends on what you want to scan and how
09:17 PM CaptHindsight: or two different speeds
09:17 PM CaptHindsight: like XY scan on a raster
09:17 PM CaptHindsight: X at a high rate, Y much lower
09:18 PM sync: you could make them equally fast tho I think
09:18 PM CaptHindsight: Laser Material Processing in 3D with 3-Axis Beam Deflection Units
09:18 PM CaptHindsight: https://www.youtube.com/watch?v=aTYv6teKRq0
09:20 PM CaptHindsight: https://www.youtube.com/watch?v=_a_myUwIFXY 3D Laser Marking
09:20 PM sync: the raylase thing only has a ballscrew for the zoom lens
09:20 PM sync: I wonder how well a voicecoil would do
09:21 PM CaptHindsight: linear motor or voicecoil
09:21 PM CaptHindsight: yeah just depends on how fast you want to scan and in which direction/vector
09:22 PM CaptHindsight: patents patents patents
09:22 PM CaptHindsight: on the obvious
09:23 PM sync: can't infringe a patent if you don't know about it
09:23 PM CaptHindsight: heh, tell that to the judge
09:24 PM CaptHindsight: back to work here
09:28 PM sync: well, at least where I'm from you cannot patent obvious solutions
09:28 PM sync: and using two polygons is an obvious solution
09:30 PM CaptHindsight: https://www.ipwatchdog.com/2017/06/17/patentability-nonobviousness-35-usc-103/id=84716/

09:47 PM Tom_L: XXCoder did you see my note about those cad files?
09:48 PM Tom_L: the 'how did you do that' ones
09:58 PM FinboySlick: CaptHindsight: I don't know who picks their video music but it's kinda groovy.
10:07 PM XXCoder: hey Tom_L a second just stopped searching
10:07 PM XXCoder: my energy is really low lol its really nasty when back is really hurting
10:10 PM XXCoder: okay is it in the file Tom_L ?
10:11 PM XXCoder: also, jthornton Tom_L look at "basic techical drawing" by spencer/dygdon
10:11 PM XXCoder: so many drawings stuff
10:14 PM Tom_L: XXCoder i linked a couple files for you
10:15 PM XXCoder: hmm dont see links? may have scrolled up
10:18 PM Tom_L: 09:18 AM Tom_L: XXCoder
10:18 PM Tom_L: start there
10:18 PM XXCoder: looking
10:20 PM XXCoder: "draw the basic flat flange then 2 drawings for the shell and do an extrude "
10:21 PM Tom_L: i turned the sketches on so you could see their outlines
10:21 PM XXCoder: is it in freecad?
10:21 PM Tom_L: oh hell no
10:21 PM Tom_L: :)
10:21 PM XXCoder: lol ok. was really wondering. sketch looked very complex
10:22 PM XXCoder: cool though. so basically make design then exturde it all out or shell
10:22 PM Tom_L: yes
10:23 PM Tom_L: actually it's just 2 octagons
10:23 PM Tom_L: the white is the actual sketches
10:24 PM XXCoder: I see it now
10:24 PM XXCoder: orange is result of shell
10:24 PM taloot: https://gd4.alicdn.com/imgextra/i3/444321513/TB2JlNKavHlJuJjSZFtXXad7FXa_!!444321513.jpg

10:25 PM taloot: linuxcnc killer sloution
10:28 PM Tom_L: XXCoder the other one is done with 2 planes with an offset at the start of the extrude
10:29 PM Tom_L: not sure you can do that in every cad package
10:29 PM Tom_L: you give it an extrude start and end point
10:30 PM XXCoder: freecad you can move start and end around
10:30 PM XXCoder: same for pockets
10:31 PM _unreal_: and the last motor has now been Rudimentary motor mounting mounting is done finally on the mini cnc
10:31 PM _unreal_: its been mountinged
10:31 PM _unreal_: hehe
10:31 PM _unreal_: I have no idea what I just said
10:32 PM drdoc: Tom_L: I would probably do that as a boundary surface in solidworks
10:32 PM Tom_L: if you don't, we sure don't
10:33 PM Tom_L: drdoc it was an exercise problem and had to meet the correct part volume too
10:33 PM drdoc: ah
10:33 PM Tom_L: :)
10:34 PM drdoc: I'd still use boundary surfaces
10:35 PM Tom_L: i don't use sw near as much as catia but i did alot of them in both just for the practice
10:35 PM drdoc: I'd love to have access to catia
10:35 PM XXCoder: finnnnnaly found it https://www.aliexpress.com/item/32971002911.html
10:36 PM drdoc: if I did I'd use it more than solidworks too
10:36 PM drdoc: :-)
10:36 PM Tom_L: i took a couple classes but my schedule limited me
10:36 PM Tom_L: both my kids have taken most of it
10:36 PM Tom_L: it's easier to navigate i think
10:36 PM drdoc: catia?
10:36 PM Tom_L: yes
10:36 PM Tom_L: but i'm just used to it
10:37 PM drdoc: the IC module certainly is
10:37 PM Tom_L: i use a thumb mouse and can zoom, rotate etc without moving my hand
10:37 PM drdoc: I took that class a couple of years ago
10:37 PM drdoc: which mouse?
10:37 PM Tom_L: logitech
10:37 PM Tom_L: ball
10:38 PM Tom_L: it works really well with it
10:38 PM drdoc: I use an Elecom Deft Pro
10:38 PM Tom_L: it's cheap but effective
10:38 PM drdoc: 8 buttons, decent programming UI, and selectable resolution
10:39 PM Tom_L: they had those space balls in the class but nobody used them
10:39 PM drdoc: I can't use a thumb ball anymore, for more than a couple of hours
10:39 PM Tom_L: i'm just used to it
10:40 PM drdoc: I'd like one of the 15-button space meese
10:40 PM Tom_L: granted my hand falls asleep if i don't move it around some
10:40 PM drdoc: I dislocated my think a couple of times throwing chain in the '80s
10:40 PM drdoc: lol, my thumb
10:41 PM drdoc: now that's catching up to me
10:41 PM Tom_L: life has a way of doing that
10:41 PM drdoc: yeah
10:42 PM drdoc: anyway, I used a Logitech thumb ball for a certain long time
10:42 PM * drdoc still has a working Marble FX
10:43 PM drdoc: anyway, is going to say one of the projects on my list is a USB macro pad
10:44 PM drdoc: I have the 10-key end of a full-size keyboard that I cut down to TKL, and a case already printed for it
10:44 PM drdoc: just need to Rich or mill the PCB and program a Teensy for it
10:45 PM drdoc: etch*
10:45 PM drdoc: Swype is killing me tonight
10:46 PM XXCoder: finally starting to feel better
10:46 PM XXCoder: pain sucks lol
10:48 PM XXCoder: failed to find power pack for my mini lathe tho :(
10:50 PM XXCoder: lol https://www.aliexpress.com/item/33018547254.html
10:50 PM drdoc: well that didn't suck
10:51 PM XXCoder: high quality FILED lenbs
10:51 PM drdoc: the free i5 sat at 8 uS for a 6 hour latency test
10:52 PM drdoc: that's with USB keyboard & mouse and ethernet up
10:52 PM _unreal_: OMG this little computer has a caveman plug on it
10:52 PM _unreal_: NON of my universal adapters fit it
10:52 PM drdoc: ?
10:53 PM _unreal_: barrel plug bug the inner peg is like 2.5mm diam
10:53 PM drdoc: damn
10:53 PM _unreal_: ARG
10:53 PM drdoc: This Just In:
10:53 PM XXCoder: 5mm od 2.5mm id is very common for china stuff lol
10:53 PM drdoc: A Dell with fan management turned off is LOUD
10:54 PM _unreal_: toshiba libretto 50ct
10:54 PM _unreal_: I got one of these at good will
10:54 PM _unreal_: tonight
10:54 PM XXCoder: yay found free porn collection there yet? lol
10:56 PM drdoc: XXCoder: I did that once
10:57 PM XXCoder: i once bought a school laptop, found bunch of docs
10:57 PM drdoc: was running a rootkit check for a printshop here in 2003
10:57 PM XXCoder: nothing important and deleted it again
10:57 PM drdoc: their firewall was a linux box and their bandwitdth usage skyrocketed
10:58 PM _unreal_: I'm going to have to go buy a universal set of plugs tomorrow to get the @#$%@#$ size I need
10:58 PM drdoc: the owner thought he'd been hacked, asked me to look at it
10:58 PM _unreal_: very annoyed
10:58 PM drdoc: the night shift dude was downloading gigs/night of kiddie porn and burning DVDs
10:59 PM drdoc: the FBI met him at the parking lot, leaving the next morning
10:59 PM _unreal_: did he get caught?
10:59 PM drdoc: far as I know he's still in prison
10:59 PM XXCoder: jeez
11:00 PM drdoc: that was an ugly gig
11:00 PM drdoc: I did depositions and interviews for months
11:00 PM XXCoder: my internship mentor explained about one of annoying and common issues with ywca (not ymca) is tons of kiddie porn emails being sent there
11:00 PM drdoc: huh
11:01 PM drdoc: that's odd
11:01 PM XXCoder: to random addresses and such. once a long while some worker gets arrested but emails never stop
11:01 PM XXCoder: it is odd he said its only at ywca he experenced such problem
11:02 PM XXCoder: heres a problem, he couldnt add "kids" and such words to filter. :( since ywca deals with women and kids a lot
11:02 PM XXCoder: so you was professional witness at court interesting
11:02 PM drdoc: I ran the building network for University of Texas' archeology labs for a few years
11:02 PM drdoc: about twice a semester I'd have to have The Talk with an intern
11:03 PM XXCoder: one arm under table type intern eh
11:03 PM drdoc: mid-90s, so our 5-10Mb/s connection was awfully tempting
11:03 PM * _unreal_ can see drdoc now "waving a finger, stop spanking it with kiddy porn"

11:06 PM drdoc: when the altavista page came up in Athena I danced

11:07 PM Tom_L: compuserv
11:07 PM Tom_L: the source
11:08 PM drdoc: _unreal_: I'd already been on BBS's and a bit of FidoNET, and MetroBBS had an IP interface for the real internet
11:08 PM XXCoder: drdoc: I got pissed after few months of double billing and refused to close my account
11:08 PM XXCoder: so I got myself banned for life from aol.
11:08 PM drdoc: AOL was... like graduating high school and enrolling in 1st grade
11:09 PM XXCoder: mid 1993? start and banned at early 1994
11:09 PM drdoc: heh, yeah
11:09 PM XXCoder: fuck aol
11:09 PM drdoc: I have an old 486 laptop that still exists because I like playing Lemmings
11:09 PM XXCoder: :)
11:10 PM drdoc: alright
11:10 PM drdoc: oh, since the CAD guys seem to be on tonight
11:11 PM drdoc: is there anything besides ESTLCam and FlatCAM that will make toolpaths from Eagle files?
11:11 PM drdoc: pcb-gcode is barely breathing
11:11 PM XXCoder: LOL https://www.aliexpress.com/item/33052047734.html
11:11 PM XXCoder: bearing sorter!
11:11 PM _unreal_: drdoc, depends on what formats you can export
11:11 PM XXCoder: actually its not bearing sorter
11:12 PM drdoc: Gerber, SVG, the usual
11:12 PM _unreal_: ok
11:12 PM XXCoder: its weird kind of 4th axis for laser
11:12 PM _unreal_: drdoc, http://maslowmakercam.000webhostapp.com/
11:12 PM drdoc: gotta love aliexpress
11:13 PM _unreal_: drdoc, check that lnk
11:13 PM _unreal_: requires flash
11:13 PM drdoc: blank page
11:14 PM XXCoder: flash lol
11:14 PM XXCoder: welcome to 0s
11:14 PM drdoc: yeah, not happening
11:14 PM XXCoder: i didnt install flash nor do I plan to
11:14 PM drdoc: ^^^^
11:14 PM _unreal_: its a very VERY nice minor cad major cam software that can import SVGs
11:14 PM drdoc: what he said
11:14 PM Tom_L: eagle has a user macro for gcode
11:14 PM _unreal_: what... ever.....
11:14 PM drdoc: Tom_L: pcb-gcode?
11:15 PM Tom_L: possibly
11:15 PM Tom_L: it's been ages since i opened eagle
11:15 PM _unreal_: drdoc, I also use carbide create
11:15 PM _unreal_: carbide will open its own file format, svg and dxf
11:15 PM _unreal_: inports
11:15 PM _unreal_: but windows software
11:16 PM drdoc: so, does maslowmaker have a page that's not Flash?
11:16 PM XXCoder: https://www.aliexpress.com/item/32864373011.html very interesting design
11:16 PM drdoc: I use Solidworks and mastercam - I'm not allergic to Windows
11:17 PM _unreal_: drdoc, no
11:17 PM _unreal_: drdoc, then use carbide create
11:17 PM drdoc: OK
11:17 PM _unreal_: FYI drdoc it will piss you off in MANY MANY ways but there are work arounds to the software errors that they have NEVER EVER from the first releases fixed
11:18 PM drdoc: for some reason, I thought Carbide Create was payware
11:18 PM drdoc: heh
11:18 PM _unreal_: aside from that you will find NO other software that works as fluid as carbide create does
11:18 PM drdoc: sounds like my kind of tool
11:18 PM _unreal_: let me get the download link for ya
11:18 PM drdoc: I'm on it
11:18 PM drdoc: thanks for the heads up

11:19 PM drdoc: Tom_L: I'm not at all pleased with Autodesk's "integration" of Eagle
11:19 PM _unreal_: drdoc, use that link
11:20 PM drdoc: ok
11:20 PM drdoc: by the way
11:20 PM _unreal_: oh oh
11:21 PM drdoc: the guy who gave me that optiplex wants me to sell a stack of 1U & 3U servers for him, on commission
11:21 PM drdoc: *and* a 30" Apple Cinema Display, with PSU & cables
11:21 PM _unreal_: random
11:22 PM drdoc: not so random; I did admin for his colo stuff while he was doing a startup
11:22 PM drdoc: it was an Austin Style Success - HP bought him out to kill the product
11:23 PM drdoc: anyhow, I'm a little tempted to sink my commission into that monitor
11:24 PM _unreal_: I miss my CRT monitors
11:25 PM XXCoder: i need very high contrast range screens
11:25 PM _unreal_: like a crt
11:25 PM _unreal_: hehe
11:25 PM XXCoder: lol yea but no room for crts :P
11:25 PM _unreal_: ya they did eat deskto space
11:26 PM XXCoder: theres new tech that uses TWO lcd panels for single screen
11:26 PM _unreal_: but DAMN they where great for gaming
11:26 PM XXCoder: frontmost is still normal lcd display
11:26 PM XXCoder: back one is grayscale for lighting control
11:26 PM drdoc: ooooh
11:26 PM _unreal_: hum
11:26 PM XXCoder: gives it million+ range
11:26 PM drdoc: yup
11:26 PM _unreal_: I'm so far out of gaming these days
11:26 PM XXCoder: it might be cheaper than oleds
11:26 PM drdoc: and pinpoint detail
11:27 PM XXCoder: unreal i dont do much gaming but my vision have some contrast issues and those 2 screens isnt great on that
11:27 PM drdoc: I gave up a 21-inch trinitron for a 20-inch FP2007 and never looked back
11:27 PM _unreal_: hehe visioin issues, I know vision issues
11:27 PM _unreal_: I got bubbles in my eyes
11:27 PM drdoc: temperature in my office went down 3 degrees instantly
11:28 PM _unreal_: semi dead areas
11:28 PM XXCoder: https://www.androidauthority.com/panasonic-announces-1000000-contrast-ratio-lcd-733904/
11:29 PM drdoc: that's worth watching
11:29 PM drdoc: Tom_L: this code doesn't look bad
11:29 PM Tom_L: oh the script?
11:30 PM drdoc: output from the Eagle g-code macro
11:30 PM Tom_L: yeah
11:30 PM XXCoder: Dell U2415 UltraSharp 24-Inch 1,920-by-1200 IPS Monitor — $199.99 (List Price $399.99; Save $200)
11:30 PM drdoc: it's bare-bones as hell
11:30 PM XXCoder: is it really that good?
11:30 PM Tom_L: well you can fix that
11:30 PM Tom_L: i may have used it once or twice
11:30 PM drdoc: I'll run it on the spoilboard first
11:30 PM drdoc: :-)
11:31 PM drdoc: it may be fine - not like making traces is complicated
11:31 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/etching/Copper1.jpg
11:31 PM Tom_L: i got plenty if you need more
11:31 PM drdoc: jeebus - how thick is that?
11:32 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/etching/Copper3.jpg

11:32 PM Tom_L: no
11:32 PM Tom_L: i'm trying to get buster installed
11:32 PM drdoc: to tell the truth, I'd keep doing toner transfer if I didn't have to drill the damn holes
11:33 PM XXCoder: ok :) mine is 1980 edition lol can get for maybe 2 bucks or 3
11:33 PM Tom_L: i just started sending em out to be made

11:34 PM drdoc: a 5.5" x 15" PCB gets pricey
11:35 PM XXCoder: tom whats funny is that it has homework in it when I bought it. 91% graded
11:35 PM XXCoder: by ed, april of 1993
11:35 PM XXCoder: i was still in school then lol
11:36 PM Tom_L: heh
11:37 PM XXCoder: bought power supply for my belt sander. hope its right one lol
11:39 PM XXCoder: jeez. homework is over 20 years old.
11:40 PM drdoc: I wonder if I can put a PWM circuit inline on this case fan
11:40 PM XXCoder: its legal for that homework to go to bar and drink
11:40 PM drdoc: if it weren't a Dell, it'd be a no-brainer
