02:10 AM rue_mohr: I must have been totally out in every aspect tho
02:16 AM rue_mohr: like
02:16 AM rue_mohr: really far
08:53 AM polprog: oh great
08:53 AM polprog: tenant has a ceiling leak
08:53 AM polprog: i can see bare rebar and water droplets coming from it
08:54 AM polprog: but the same place from the flat on the top is completely dry
11:21 AM rue_bed2: hu?
11:22 AM rue_bed2: that doesn't sound right on a few levels
11:22 AM rue_bed2: how is the place built?
11:22 AM rue_bed2: I LOVE this switch!
11:22 AM rue_bed2: just wish it were a bit smaller
11:38 AM Tom_L: switch?
02:25 PM Tom_L: howz the smoke up there today?
02:51 PM rue_shop1: thick
02:52 PM rue_shop1: ma just came up from the marina to escape the worst of it
02:52 PM Tom_L: hard to breathe?
02:52 PM Tom_L: ahh
02:52 PM rue_shop1: I'm not having issues
02:52 PM rue_shop1: the cats got a bad throat
02:52 PM Tom_L: saw a video of some campers that spent the night in a cold lake to avoid the spark showers
02:53 PM Tom_L: helo'd out
02:53 PM Tom_L: what you workin on today?
02:55 PM rue_shop1: bench power supply
02:55 PM rue_shop1: I have a challenge
02:56 PM rue_shop1: I'd like to make a bezel for an led indicator
02:56 PM rue_shop1: but
02:56 PM rue_shop1: I'd like it to be square
02:56 PM rue_shop1: /rectangular
02:57 PM rue_shop1: but the hole would need to be ~ 5mmx2mm
02:57 PM rue_shop1: and I cant cut that with the cnc
02:58 PM rue_shop1: I'd like white metal, aluminum maybe
02:58 PM Tom_L: why can't you cut it?
02:58 PM rue_shop1: I wonder if I should just silver paint a plastic one
02:58 PM Tom_L: won't fit under where the hole needs to be?
02:58 PM rue_shop1: I was having issues with 1mm bits
02:58 PM Tom_L: mmm
02:58 PM rue_shop1: just a bezel
02:58 PM rue_shop1: wonder if I shoudl just try it with a 1mm
02:59 PM Tom_L: i thought about making one of those router adapters from brass but i probably won't
02:59 PM rue_shop1: oh, I ahve some 1.5mm
02:59 PM rue_shop1: hmm, this IS 2mm
02:59 PM Tom_L: just cut a slot then
03:00 PM Tom_L: few passes
03:00 PM rue_shop1: hmm, moon has some 2mm bits here
03:01 PM rue_shop1: I have some really small files
03:01 PM Tom_L: is he a programmer by trade?
03:01 PM Tom_L: seems to do quite a bit of it
03:05 PM rue_shop1: na, electrician
03:05 PM Tom_L: is that how you met?
03:10 PM rue_shop1: na, the robitics thing I was doing
03:10 PM Tom_L: hmm
03:10 PM rue_shop1: the plastic bezels/holders I have only fit OLD special leds, and they all run too dim
03:10 PM rue_shop1: hmm
03:10 PM Tom_L: yeah the early ones weren't stellar
03:12 PM Tom_L: stove element?
03:12 PM rue_shop1: kiln shop -> nichrone wire
03:12 PM Tom_L: yeah, she just tossed an old toaster :(
03:12 PM rue_shop1: they might also have some ceramic cylinders you can wrap it on
03:13 PM rue_shop1: hair dryer, but I'm not sure the guage is up to it
03:13 PM rue_shop1: off they need a brake resistor
03:13 PM Tom_L: the local guy that had nichrome wire closed
03:13 PM rue_shop1: odd
03:13 PM rue_shop1: is there a kiln supply shop? potter?
03:13 PM rue_shop1: y
03:13 PM Tom_L: it has an internal one but they recomend an external one for rough use
03:13 PM Tom_L: dunno
03:14 PM Tom_L: i got some ideas though
03:14 PM rue_shop1: ok
03:14 PM rue_shop1: hmm I wonder if I have one
03:14 PM rue_shop1: 100 ohms
03:14 PM Tom_L: wonder what the elements are like in the toaster oven
03:14 PM Tom_L: does the resistance change on nichrome when hot?
03:15 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/resistor1.jpg
03:15 PM Tom_L: i could use that
03:16 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/resistor2.jpg
03:16 PM Tom_L: maybe i will. i haven't used it for much else lately
03:16 PM rue_shop1: nothing bigger than 50W
03:17 PM rue_shop1: hmm, wouldn't suggest it, too far
03:17 PM Tom_L: huh?
03:17 PM Tom_L: too long?
03:17 PM rue_shop1: 175w for 500 ohms, so like 87w for 250 ohms...
03:18 PM Tom_L: mmm true
03:20 PM rue_shop1: their available from china in a nice metal package that can be stuck to a heatsink
03:20 PM rue_shop1: :/
03:20 PM rue_shop1: I was looking at them to make a battery tester for work
03:20 PM rue_shop1: but they guys convinved me to give in and have us get a $700 electronic tester that we now aren't sure works that well
03:24 PM Tom_L: maybe i'll look for an amazon free shipping one
03:40 PM Tom_L: figures
03:53 PM Tom_L: i probably won't need it right away
03:59 PM rue_shop1: I'm going to mock up a bezel-less indicator with some paint mask from the back
04:00 PM Tom_L: https://www.amazon.com/LM-YN-Wirewound-Electronic-Aluminium/dp/B076W85378/ref=sr_1_5?dchild=1&keywords=100w+100+ohm+resistor&qid=1599944166&sr=8-5
04:00 PM Tom_L: should work?
04:01 PM Tom_L: they said 100w but i was gonna get 150 to be safe meh
04:13 PM rue_mohr: yes, be sure to give them a good heatsink
04:24 PM Tom_L: fins or just a block of alum?
04:24 PM rue_mohr: well, go fins
04:27 PM Tom_L: says to arrive monday
04:57 PM rue_mohr: https://twitter.com/RueNahcMohr/status/1304900930203037696
04:58 PM Tom_L: at least i'll have a spare
04:58 PM rue_mohr: I dont think I can do as good a job if I make an actual bezel that fits thru the plexi
04:59 PM Tom_L: hold on
04:59 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/itx/frontled1.JPG
04:59 PM Tom_L: round lexan bar cut to fit
04:59 PM rue_mohr: :)
04:59 PM Tom_L: led behind
05:00 PM rue_mohr: yea
05:00 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/itx/frontpannel2.JPG
05:00 PM rue_mohr: you painted the back of the lexan?
05:00 PM Tom_L: no
05:00 PM rue_mohr: ah
05:00 PM Tom_L: sanded
05:00 PM Tom_L: the red one isn't very bright compared to the blue
05:01 PM rue_mohr: did you do the buttons?
05:01 PM Tom_L: yeah
05:01 PM rue_mohr: have a shot?
05:01 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/itx/itx_thumb_index.php
05:01 PM Tom_L: maybe one there, i'm not sure
05:02 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/itx/frontled3.JPG
05:02 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/itx/frontled4.JPG
05:04 PM Tom_L: just a steel dowel with a washer soldered to the back end
05:04 PM Tom_L: iirc
05:04 PM rue_mohr: k
05:04 PM Tom_L: nothing fancy
05:04 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/itx/dvdmount2.JPG
06:26 PM rue_shop1: change bit, forget to load new file
06:26 PM rue_shop1: fancy dance trying to stop the machine and not lose zero
06:30 PM rue_shop1: I think I'm gonna regret not having holding tabs on that cutout...
06:35 PM Tom_L: hold it manually
06:35 PM Tom_L: it's a trick but works most of the time
06:40 PM rue_shop1: amost, it jammed the spindle for a sec before I could pullit out
06:40 PM Tom_L: i sometimes hold them down with a screwdriver or something
06:41 PM Tom_L: usually works
06:43 PM rue_mohr: I'm making a little trim for the siwtch handle
06:43 PM rue_mohr: out of some 1/4" alum
06:44 PM Tom_L: mmm
06:53 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1170322.jpg
06:53 PM rue_mohr: I'll have to file those inner corners square
06:53 PM rue_mohr: scrap 101 :)
06:57 PM Tom_L: looks good
08:20 PM MoonyMoon: rue_mohr: !
08:26 PM MoonyMoon: rue_shop2: :|
08:31 PM rue_shop1: with lots of touch up that came out ok
08:31 PM rue_shop1: MoonyMoon, hows you
08:31 PM rue_shop1: ma ate all yer noodles
08:37 PM MoonyMoon: why????
08:37 PM rue_mohr: she does that, I lock my shop now :/
08:38 PM MoonyMoon: :(
08:38 PM MoonyMoon: well if she finds me a good deal on a RV, we can call it square. :P
08:39 PM MoonyMoon: can you transfer me the dxf for that 4-11/16 box?
08:39 PM rue_mohr: yes
08:40 PM MoonyMoon: cool
08:42 PM rue_mohr: http://ruemohr.org/~ircjunk/objects/main.dxf
08:42 PM MoonyMoon: Danke :)
08:42 PM MoonyMoon: done
08:44 PM rue_mohr: you gonna make a plate for something?
08:44 PM MoonyMoon: yeah, slightly bigger and blank for custom drilling :)
08:45 PM rue_mohr: https://twitter.com/RueNahcMohr/status/1304956829097586689
08:45 PM rue_mohr: not sure if I should just do the painted indicator
08:45 PM rue_mohr: I want it to have some 3d prescence
08:45 PM rue_mohr: Tom_L, didn't I start that as a bezel for an led?
08:46 PM rue_mohr: wait, where did this road turn?
08:46 PM MoonyMoon: to madness
08:46 PM rue_mohr: pillars!
08:47 PM Tom_L: naw, actually i think it started there
08:47 PM rue_mohr: getting dark
08:47 PM MoonyMoon: rue_mohr: link me to the source for your UNITS program
08:47 PM rue_shop1: hmm
08:48 PM rue_shop1: https://github.com/ruenahcmohr
08:48 PM rue_shop1: ?
08:48 PM rue_shop1: ohm, circle
08:48 PM rue_shop1: calc
08:48 PM rue_shop1: (Equation)
08:49 PM rue_shop1: huh
08:49 PM rue_shop1: no wait
08:49 PM rue_shop1: wtf
08:49 PM MoonyMoon: are they all Equation?
08:49 PM rue_shop1: no, I didn't write units
08:49 PM rue_shop1: your tricking me!
08:49 PM MoonyMoon: am I?
08:49 PM rue_shop1: apt-get install units
08:49 PM MoonyMoon: goly im dumb
08:49 PM Tom_L: so what you gonna do for an led bezel now that you turn it into a switch shroud?
08:50 PM rue_shop1: hahaha
08:50 PM MoonyMoon: moon@DarkStar:~$ apt-cache search units | grep "^unit"
08:50 PM MoonyMoon: units - converts between different systems of units
08:50 PM MoonyMoon: units-filter - Parser for expressions concerning physical values
08:50 PM MoonyMoon: yup
08:50 PM MoonyMoon: XD
08:50 PM rue_shop1: technically I dont think thats how it went down
08:50 PM Tom_L: make one of those from clear plastic and illuminate it when the switch is on
09:03 PM MoonyMoon: rue_shop1: how can I get this modified file back to you, and can you cut it on the army of robots machine?
09:11 PM MoonyMoon: im going to wathc a movie now, wil connect later :)
09:26 PM Tom_L: pastebin it
09:27 PM Tom_L: https://paste.debian.net/
09:59 PM rue_mohr: uh...
09:59 PM rue_mohr: the phone system just ate its raid1 array?
10:00 PM rue_mohr: god, this thing eats hardware like you would not believe
10:00 PM rue_mohr: its at 7 hard drives, 1 power supply and 2 motherboards
10:00 PM rue_mohr: not including whatever it just did to these drives
10:04 PM Tom_L: wasn't it the media player last week?
10:05 PM rue_mohr: yes, but I think I know what might have happened there
10:05 PM rue_mohr: the vociecoil driver for the head burned out
10:05 PM rue_mohr: I had the drive mounted on its side
10:05 PM rue_mohr: I dont think it was rated for that
10:06 PM rue_mohr: so I dont think the heads were balanced
10:06 PM rue_mohr: over worked the drivers and they gave out
10:06 PM Tom_L: huh, i never knew that mattered
10:06 PM rue_mohr: once upon a time, on some drives, it did
10:07 PM rue_mohr: this will be the big test of raid1
10:07 PM rue_mohr: can I get the system back
10:09 PM rue_mohr: these ones are mounted funny too
10:18 PM rue_mohr: now it wont boot
10:18 PM rue_mohr: wow
10:19 PM Tom_L: that went downhill quick
10:19 PM Tom_L: so much for raid
10:21 PM MoonyMoon: https://paste.debian.net/1163573/
10:22 PM MoonyMoon: rue_shop1: can you cut this out for me on army of evil robots
10:23 PM Tom_L: what is it?
10:23 PM MoonyMoon: a cover for a electrical box
10:23 PM MoonyMoon: just blank and oversized
10:24 PM Tom_L: wood, metal, plastic, ceramic.... ?
10:24 PM MoonyMoon: Al - metal
10:24 PM MoonyMoon: 10 or 8 AWG thick :P
10:25 PM Tom_L: 1/8 - 3/16"
10:25 PM MoonyMoon: yeah i supose
10:27 PM MoonyMoon: maybe thinner rue would know the stock 3/32..??
10:29 PM Tom_L: double wide
10:29 PM Tom_L: you can't buy one?
10:30 PM Tom_L: those seem rather common
10:30 PM rue_mohr: the backup phone systems motherboard wont turn on
10:30 PM Tom_L: i won't try to call you right now then
10:32 PM rue_mohr: cmos clear didn't work
10:32 PM Tom_L: wiggle all the plugs
10:32 PM rue_mohr: why the hell does the universe do this to me sometimes?
10:32 PM rue_mohr: I'm going to jab a wire into the power_on for the power supply
10:32 PM Tom_L: how old is it?
10:34 PM Tom_L: MoonyMoon, you don't need a cnc for that
10:34 PM Tom_L: cut a square and drill some holes in it
10:36 PM MoonyMoon: yeah but its a beauty when its cnc'd
10:37 PM rue_mohr: wtf
10:37 PM MoonyMoon: ?
10:37 PM rue_mohr: the harddrives didn't spin up, they had power tho
10:37 PM rue_mohr: I unplugged them from the mb and now they spin up
10:37 PM rue_mohr: motherboard in the *new* system is dead
10:37 PM MoonyMoon: current sunk?
10:37 PM rue_mohr: no idea
10:37 PM rue_mohr: w t f
10:37 PM MoonyMoon: blast it with piss!
10:37 PM rue_mohr: why is this being done to me?
10:38 PM MoonyMoon: past life karma?
10:40 PM rue_mohr: its a new motherboard
10:40 PM rue_mohr: its not more than like 5 years old
10:41 PM rue_mohr: the f**8ing universe will break the laws of physics if it has to sometimes to screw me over
10:41 PM rue_mohr: and its being really into screwing me over latley
10:41 PM rue_mohr: SERIOUSLY
10:42 PM MoonyMoon: come roast a hotdog tomorrow!
10:42 PM Tom_L: ever cook one with an extension cord?
10:44 PM rue_mohr: MoonyMoon, no
10:45 PM rue_mohr: not till I have a power supply built, a running phone system, driveway pillars or winter...
10:45 PM rue_mohr: and all the other crap I'm slated for before I die
10:45 PM rue_mohr: just ARG
10:57 PM rue_mohr: ok, usb adapter seems to say the first drive is ok
10:57 PM rue_mohr: maybe I just need to find another motherboard
10:59 PM Tom_L: MoonyMoon, http://tom-itx.no-ip.biz:81/~webpage/rue/moon/cover.jpg
11:00 PM rue_mohr: ok
11:00 PM rue_mohr: I'll leave this drive checking
11:06 PM rue_shop1: its enough to make me drink
11:06 PM * rue_shop1 slurps back more tea
11:07 PM rue_shop1: so Tom_L
11:07 PM rue_shop1: on your software, you can specify a finishing pass automatic?
11:07 PM rue_shop1: or you have to set it up manually?
11:08 PM Tom_L: it will allow for a finish pass
11:08 PM rue_shop1: on thhat switch bezel, It left some marks, I can do a finish pass, but I have to manually set it up
11:08 PM Tom_L: then i do an offset cut
11:08 PM rue_shop1: what would you normally use for a finish? 5 thou?
11:08 PM Tom_L: 2-5
11:08 PM rue_shop1: k
11:08 PM Tom_L: depending on how tall it is
11:09 PM rue_shop1: 7mm
11:09 PM rue_shop1: on a 1/8" bit
11:09 PM Tom_L: i extruded that to 5mm
11:09 PM Tom_L: one pass
11:09 PM Tom_L: on that
11:09 PM Tom_L: maybe 2 at the most
11:09 PM rue_shop1: spiral flue or straight?
11:09 PM Tom_L: all i have are spiral
11:10 PM Tom_L: but some are high helix
11:10 PM Tom_L: i might use a .250 cutter on that just to get it done quicker
11:10 PM rue_shop1: ok, I wonder if I should try for a led bezel
11:10 PM rue_shop1: I dont think I can clean out a 2mmx5mm hole with a file
11:11 PM Tom_L: got some needle files?
11:11 PM Tom_L: i got a set different shapes
11:11 PM Tom_L: https://www.amazon.com/Piece-Precision-Needle-File-Set/dp/B006N3EPKE
11:12 PM Tom_L: some are smooth on one or two sides so all you cut is one or two sides
11:12 PM Tom_L: not all 4
11:13 PM rue_shop1: I have some small chineese files that are so crude you can tell they were hand smashed
11:14 PM Tom_L: mine are cheap too
11:14 PM rue_shop1: I'll try it
11:14 PM rue_shop1: I'm only going to use a 1/8" plate tho
11:15 PM Tom_L: cut a slot then file it square if you want square
11:15 PM Tom_L: just the corners is all you gotta file
11:16 PM Tom_L: the canned pocket cycles i used on that round brass are quick but i don't care for how they cut sometimes
11:16 PM Tom_L: couple clicks and done
11:16 PM Tom_L: i used to do it manually with offsets
11:18 PM rue_shop1: I have to make a perim thats specifically back by the pass and make it two jobs
11:18 PM Tom_L: due to the size of it?
11:18 PM Tom_L: i had to do that on my sherline when i did my drill plates
11:19 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Y_Axis_Plate2.jpg
11:19 PM Tom_L: there are 2 spots in the middle top & bottom i used for alignment
11:19 PM Tom_L: then flipped it 180 deg to do the other half
11:20 PM rue_shop1: no
11:20 PM rue_shop1: if I want to do a finish pass
11:21 PM Tom_L: oh
11:21 PM Tom_L: i just do an offset
11:21 PM Tom_L: and it goes around again a little closer
11:21 PM Tom_L: i generally do that manually
11:25 PM Tom_L: if i use a pocket routine i can offset the wall and/or the floor
11:25 PM Tom_L: then do a finish pass
11:26 PM rue_shop2: oh
11:27 PM Tom_L: more than one way to approach it
11:27 PM rue_shop2: do the pass with a larger bit setting
11:27 PM rue_shop2: then reduce and and redo
11:27 PM Tom_L: you can but don't have to
11:27 PM rue_shop2: 3 thou
11:27 PM rue_shop2: .08m
11:27 PM rue_shop2: m
11:28 PM Tom_L: i just offset the path not the cutter
11:28 PM Tom_L: i always program the center of the cutter
11:28 PM Tom_L: not the edge
11:29 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/P1.jpg
11:30 PM Tom_L: for example of the 2 light blue, the last one is the finish pass
11:30 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/P3.jpg
11:31 PM Tom_L: that was a clevice mount or something
11:33 PM Tom_L: gnite
11:35 PM rue_shop1: outside profile
11:36 PM rue_shop1: so I'll tell it the bit is 1.5+0.08
11:36 PM rue_shop1: 1.58
11:36 PM rue_shop1: then I'll redo it, with a bit thats really 1.5
11:36 PM rue_shop1: it'll pull it in tighter
11:38 PM Tom_L: what software?
11:47 PM rue_shop2: bamcam and grbl
11:48 PM rue_shop2: cambam?
11:48 PM rue_shop2: its the limit of usefull
11:48 PM rue_shop2: (lower)
11:51 PM rue_shop2: ok well its working on it
11:51 PM rue_shop2: only 10mm/min. so, it'll be a while
