12:03 AM rue_mohr: see the 3 way 5 bearing grab?
12:03 AM zhanx: yep
12:03 AM zhanx: i see the bar wear also
12:03 AM rue_mohr: I'll get a pic of the other thing, the slider block
12:03 AM katsmeow: the bearings are failing? getting sloppy?
12:03 AM rue_mohr: no
12:03 AM katsmeow: what if you used the inner race as a sleeve bearing?
12:03 AM katsmeow: square rod should wear less, because you will have more contact area to the outer race
12:03 AM katsmeow: and bearings arn;t meant to be used that way anyhoo, altho i do too
12:03 AM katsmeow: that looks like you sawed onit
12:03 AM rue_shop3: forgot the camera, try that again
12:04 AM * katsmeow notes she cannot be heard, and sits in theback of the class
12:08 AM katsmeow: ILLEGAL UNHANDLED NULL POINTER EXCEPTIONAL FAULT. ?
12:08 AM rue_shop3: :)
12:08 AM rue_shop3: I was just grabbin the camera and taking pics
12:08 AM * katsmeow wonders if her HP core duo wold work better after heating on a toaster oven too
12:08 AM rue_shop3: kat, I'm gonna take the remaining sleeve bearings and make 'graphine composite' sliders ( from carpender pencil lead)
12:09 AM katsmeow: o
12:09 AM rue_shop3: I been showering with a few carpenter pencils to liberate their lead
12:09 AM rue_shop3: got one day-beofre-yesterday
12:09 AM katsmeow: will you be making things to sell , to make the printer pay for itself?
12:10 AM rue_shop3: its just for projects right now
12:10 AM rue_shop3: tho, a project did just come up I might be able to sell
12:11 AM rue_shop3: training hooks for climing vines
12:11 AM rue_shop3: ^b
12:12 AM katsmeow: training hoboks? isn't that a Japanese snake, or a SR71 based there?
12:13 AM rue_shop3: I'm sorry I cant remember the name of the vine right now
12:14 AM katsmeow: i did an uninstall/install of firefucks today, and it noticed i was reinstalling and loaded up my old bookmarks and addons
12:15 AM katsmeow: so,,, today i learned uninstalling Fiarfucks doesn't actually
12:18 AM rue_mohr: I dont think it usually deletes them
12:18 AM katsmeow: i manually deleted c:\program files
12:18 AM katsmeow: mozilla\
12:18 AM rue_mohr: they might be in the registry tho
12:18 AM rue_mohr: nobody ever cleans out their registry ads on uninstall
12:18 AM rue_mohr: adds
12:18 AM katsmeow: well, so far it is not running 100% cpu yet
12:18 AM rue_mohr: have anything open?
12:18 AM katsmeow: one forum and two ebay pages
12:18 AM rue_mohr: and its not 100%?
12:18 AM katsmeow: did open google news and reuter news
12:18 AM katsmeow: nope
12:18 AM rue_mohr: I find that it idles about 14%, when NOTHING is happening
12:18 AM rue_mohr: so I usually suspend it till I need to use it more
12:18 AM katsmeow: it's also at 283 Meg of memmory, usually it's at 600 Meg by now
12:19 AM rue_mohr: ooooo maybe they acautlly fixed soemthing....
12:20 AM katsmeow: the uninstal/reinstal helped Tiggr5 too, it was taking 20 minutes just to launch FF on that puter
12:20 AM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap3/p1090923.jpg thats the machine
12:21 AM katsmeow: big Dake
12:21 AM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap3/p1090922.jpg these are the encapsulated nuts I used when upgrading to 5mm Z rod
12:21 AM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap3/p1090921.jpg overview of the 5mm Z
12:22 AM katsmeow: it's after midite again
12:25 AM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap3/p1090920.jpg the slider block I replaced one of the linear bearings with, the hook under the rod is just so the table dosn't fall off if you tip the printer upside down
12:25 AM rue_mohr: katsmeow, welcome to tommorow
12:25 AM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap3/p1090919.jpg the other side still has two lm8uu on it
12:25 AM rue_mohr: gonna replace those tho, their sloppy
12:25 AM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap3/p1090918.jpg the 2 point grab of the back of the X carriage
12:25 AM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap3/p1090917.jpg a bit of a better shot of the 3 way, 5 point grab on the other side of it
12:25 AM rue_mohr: Dake? arbour press?
12:25 AM rue_mohr: zhanx, ^ ?
12:25 AM katsmeow: yeas
12:25 AM katsmeow: the big grey thing
12:25 AM * katsmeow once had a baby one for making ribbon cable connections
12:25 AM rue_mohr: Dake, never heard that before
12:25 AM rue_mohr: I make a round punch die for it :)
12:26 AM rue_mohr: it worked, I was impressed
12:26 AM katsmeow: company name, who made your's?
12:26 AM rue_mohr: ... not sure, back inside now, can I look it up tommroow?
12:26 AM katsmeow: maybe
12:28 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/sparrow1/p1090916.jpg
12:28 AM rue_mohr: I did a bunch more welds to the pipe bender for the bot
12:28 AM rue_mohr: its solid now, gonna try bending pipe WHEN THE FEAKING RAIN LETS UP
12:28 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/sparrow1/p1090915.jpg sloppy weld
12:29 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/sparrow1/p1090914.jpg sloppy weld
12:29 AM katsmeow: nice rollers
12:29 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/sparrow1/p1090913.jpg sloppy weld
12:29 AM rue_mohr: THEY TOOK ME 3 YEARS TO MAKE!!! (arg)
12:29 AM katsmeow: what will you tur them with ?
12:29 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/sparrow1/p1090912.jpg
12:29 AM rue_mohr: that big gear motor
12:30 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/sparrow1/p1080968.jpg
12:30 AM katsmeow: ah
12:30 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/sparrow1/p1090053.jpg
12:30 AM rue_mohr: it runs a bit fast tho
12:30 AM rue_mohr: about 1.5 - 2'/sec
12:31 AM rue_mohr: I'm bending thin pipe, I dont know if I'll have to fill it with sand
12:31 AM rue_mohr: and I dont kow if those rollers will hold up
12:31 AM katsmeow: depends on the radius of the bend
12:32 AM rue_mohr: I need to make control cages for 2 bots
12:32 AM rue_mohr: yea, actually, I need that now
12:33 AM rue_mohr: all the plan on the wall says is 3" between them, I think the inner one is 8'
12:34 AM rue_mohr: the drive force goes thru one of the rollers, I hope that wont be a problem
12:34 AM katsmeow: you remember my roller for bending 2" wide 1/4 thick steel?
12:34 AM rue_mohr: I dont remember what you used
12:35 AM katsmeow: i posted an avi of it running too
12:37 AM rue_mohr: do you still ahv the pics up?
12:38 AM katsmeow: no
12:38 AM katsmeow: might have deleted them, dunno where they are
12:39 AM rue_mohr: clamatis
12:40 AM rue_mohr: wow, thats one hell of a memory delay
12:41 AM katsmeow: found two avi
12:42 AM katsmeow: dated 2010 and 2014 , different steel, different cameras, same roller
12:43 AM katsmeow: uploading
12:44 AM katsmeow: i think one reasoni took them down is everyone who had nix bitched at me that they could notplay avi
12:44 AM rue_mohr: everythign is you tubbable
12:44 AM rue_mohr: avi can be a generic wrapper for anything tho
12:44 AM rue_mohr: they did that with wav too
12:45 AM rue_mohr: when you really read the standard, you can put anything in it
12:45 AM rue_mohr: images, virus, have attit.
12:46 AM katsmeow: ok
12:46 AM * katsmeow kills the upload
12:46 AM rue_mohr: ? no no
12:46 AM katsmeow: ?
12:47 AM rue_mohr: I know your some standard for it, I can probably play it direct, or if its youtube, chomium can play it
12:47 AM katsmeow: vlc plays it
12:47 AM rue_mohr: ok
12:48 AM katsmeow: 10 min eta
12:48 AM rue_mohr: ok
12:54 AM katsmeow: i just played them in vlc on the laptop, it's the first time i have heard the audio on them
12:55 AM katsmeow: the 4ft roll is 1/4 thick windy noisey and tiny pic , the later one is 3ft roll of 1/8 steel on a much better camera
12:55 AM katsmeow: eta 2:30
12:56 AM katsmeow: the rollers are the oem cable drums that came on them, all aluminum
12:57 AM katsmeow: it is adjustable, hence a 4ft roll and a 3ft roll
12:57 AM rue_mohr: oh its comming back to me
12:58 AM katsmeow: http://DesignerThinking.com/images/first_3ft_rib_rolling.avi 63MB
12:58 AM katsmeow: http://DesignerThinking.com/images/4ft_rib_rolling.avi 2.3 MB
12:59 AM katsmeow: the wrench is just to get the 1/4 started onto the 3rd roller
12:59 AM katsmeow: it is bidirectional tho
01:00 AM katsmeow: for really long rolls, i did many hoops in one length of steel, and cut them off as they came off the rollers
01:03 AM rue_mohr: cat on desk
01:04 AM katsmeow: act calmly
01:04 AM katsmeow: program the arms to all pet the cat
01:08 AM rue_mohr: try to protext the arduino from drool
01:09 AM rue_mohr: not a drool rated device
01:09 AM katsmeow: and static, from friendly rubbing upon?
01:12 AM katsmeow: i knew an "engineer" in the early 1980's, some days she could net get within 3ft of benches without popping all the cmos on them
01:13 AM katsmeow: would not wear cotton,,, it wasn;t "feminine"
01:13 AM rue_mohr: how did you adjust the heights rigth on those?
01:14 AM katsmeow: mounted center one on allthread
01:14 AM rue_mohr: ok, cant really see it
01:14 AM katsmeow: adjustments was underneath, by that wrench
01:14 AM rue_mohr: k
01:15 AM katsmeow: i wasn;t sure if i might have needed to adjust tilt, so i allowed for doing that
01:15 AM katsmeow: turns out, didn;t need to
01:16 AM katsmeow: never tried to turn a cone section, but prolly can
01:16 AM * rue_mohr burries himself in the arduio problem he's working on for a min
01:17 AM katsmeow: you should move the cat off it first
01:17 AM rue_mohr: she will be back
01:18 AM katsmeow: have yu considered a morsel launcher that's triggerd by her entering a room, shooting a kibble across the room and bouncing off the wall or furniture?
01:19 AM rue_mohr: they like that
01:20 AM rue_mohr: I'm trying to get an arduio ethernet module working
01:22 AM rue_mohr: >:( not working!!!!
01:22 AM katsmeow: please allow it to accept a url clocked in, and go fetch as if it were a hardware version of wget
01:30 AM katsmeow: i would buy them from you
01:30 AM rue_mohr: it wont talk to the module and there is no link light
01:31 AM rue_mohr: eating supper
01:49 AM katsmeow: ANYmal video on yt about the robot dancing, has NO MOTION IN IT, there's NO dancing going on
01:59 AM rue_mohr: this doesn't add up
01:59 AM rue_mohr: there is no code for the SPI on this chip
01:59 AM katsmeow: add it sideways?
02:04 AM katsmeow: on yt : iStruct
02:07 AM katsmeow: on yt: Petoi opencat demo
02:07 AM rue_mohr: arduino has exampels taht are asupposed to work
02:07 AM rue_mohr: trying to see whats wrong
02:09 AM rue_mohr: it dosn't help that rx and tx are crossed over in half the documenttion
02:09 AM rue_mohr: and there is ambiguity on what pins is chip selelct
02:09 AM rue_mohr: and its all burried in libraries
02:11 AM katsmeow: prolly all developed by someone n nix
02:12 AM rue_mohr: no, most arduino is widnows
02:12 AM rue_mohr: did you make up a box of all the programmer(s) you have?
02:12 AM katsmeow: no
02:13 AM rue_mohr: would you tommorow?
02:13 AM rue_mohr: or today, whatever
02:13 AM katsmeow: not in the mood tonite, was nearly arrested today at post office, i refused to leave AFTER the manager said he had told carriers to not deliver any more packages to me, and he refused to say why
02:13 AM rue_mohr: you mentioned that
02:13 AM rue_mohr: maybe int ehmorning
02:28 AM katsmeow: guy made a lathe from scratch, playing video on yt, the vibration is making the bolts (which hold it together) back out
02:30 AM rue_mohr: k
02:34 AM katsmeow: on yt : Laikago
02:34 AM rue_mohr: ff cable
02:35 AM rue_mohr: fffffffffffffffffffffffff
02:35 AM rue_mohr: ok I give up for the night
02:35 AM rue_mohr: I have a m328 as a webserver on the network
02:35 AM rue_mohr: I'll work on the stm32 later
02:36 AM katsmeow: does just anyone buy it from you?
02:36 AM rue_mohr: what?
02:37 AM rue_mohr: I buy stuff from china
02:37 AM rue_mohr: only people who understand what I'm talking about
02:37 AM rue_mohr: but grrrr
02:37 AM katsmeow: i STILL mean the programmed plug-in-and-it-works units
02:37 AM rue_mohr: there is no such thing
02:38 AM rue_mohr: nothing ever just works anywhere
02:38 AM katsmeow: you have one : [02:36:am] <rue_mohr> I have a m328 as a webserver on the network
02:38 AM rue_mohr: ever
02:38 AM rue_mohr: yea, quite a fight
02:39 AM rue_mohr: just arg
02:47 AM * katsmeow ................................................ hopes you do well and signs off
04:56 PM Tom_itx is now known as Tom_L
10:33 PM katsmeow: <coff>
10:36 PM rue_bed: ...
10:37 PM rue_bed: teaaaaaa
10:44 PM rue_mohr: so,
10:44 PM rue_mohr: at some point
10:44 PM * katsmeow points to the otehr point
10:44 PM rue_mohr: I'd like to write a library for working out the timing and dithering to scroll segments across 7 segment displays, but 'smoothly'
10:45 PM rue_mohr: aka, the segments are turns on and off based on a velocity across their real-world positions
11:03 PM * rue_mohr tries to initialize
11:03 PM rue_mohr: have to focus
11:04 PM rue_mohr: I was wondering about using a touchpad for position detection of thumb for robot gripper control (reduced, simplified controller)
11:05 PM * rue_mohr chases tail, at a walking pace..
11:06 PM rue_mohr: 8000RPM, whats more noisy, the engine or the chain reduction drive?
11:06 PM katsmeow: engne
11:06 PM rue_mohr: 8000RPM, whats more noisy, the engine or the gear reduction drive?
11:06 PM katsmeow: but at 8000 rpm, the chain wonl;t last long
11:07 PM rue_mohr: I wonder if I can use a belt reducton without losing too much
11:07 PM katsmeow: flat belt, yeas, "timing belt"
11:07 PM rue_mohr: what do they use on the engines that they nitro?
11:07 PM rue_mohr: for timing?
11:07 PM rue_mohr: hmm
11:08 PM rue_mohr: will a timing belt take 2HP?
11:08 PM rue_mohr: suppose it could
11:08 PM rue_mohr: at 8k
11:08 PM rue_mohr: not much tension
11:08 PM rue_mohr: most of the force is just outward from all the spinning pullies
11:08 PM katsmeow: timing belts cantake 100hp, just depends on other variables
11:09 PM rue_mohr: I wonder how many watts you lose in a belt drive at 2hp, 8k
11:09 PM katsmeow: there a company running hovercraft across the english channel several time per day, the push props are turnes wth belts
11:09 PM rue_mohr: I'm only working with 2hp in the first place
11:09 PM katsmeow: a v belt will lose all the 2hp
11:09 PM rue_mohr: I dont know how much spare there is on the design
11:10 PM rue_mohr: I'd expect at least 40w loss on a high speed belt
11:10 PM rue_mohr: tho I cant mentally model that well, with all that air moving everywhere
11:11 PM katsmeow: the thinner the better, or i'd suggest a round belt
11:11 PM rue_mohr: you know, I'm amazed by the gasket I'm using on the spindle of the cnc
11:12 PM rue_mohr: at 6k average speed, and the cnc torque, its been holding REALLY well
11:12 PM rue_mohr: its running so fast most of the time its stretching itself away from the pullies
11:13 PM rue_mohr: I bed the machinists handbook says a lot about belt drives
11:13 PM * rue_mohr walks after tail
11:13 PM rue_mohr: more tea
11:14 PM rue_mohr: would hooking the tea maker to the network for automatic activation benifit my bottom line performance
11:14 PM rue_mohr: ?
11:14 PM rue_mohr: a supper machine would
11:14 PM rue_mohr: need to finish the thermal controller
11:14 PM katsmeow: print allready-cooked spagetti
11:14 PM rue_mohr: did I tell you the screw sorter now has 28 bins?
11:15 PM katsmeow: no
11:15 PM rue_mohr: heh
11:15 PM rue_mohr: tommorow I'll get the student working on programming the arm to load screws onto the delivery bot
11:15 PM rue_mohr: and I need to work ont eh vibration feeder
11:16 PM katsmeow: crossed my lil mind to pre-bin pasta over a bowl(s), cylinder of water of kown volume, shove into nukebox, turn iton
11:16 PM rue_mohr: oh yea, my water dispencer, thats part of the supper machine project
11:16 PM rue_mohr: I got a tap for the sink water line
11:16 PM rue_mohr: and I have a valve
11:16 PM rue_mohr: and a regulator
11:17 PM rue_mohr: I need to know if orifice*time results in predictable volume
11:17 PM katsmeow: no
11:17 PM rue_mohr: I'm gonna regulate it down to something stupid like 5 psi
11:17 PM katsmeow: mineral clogs change the volume thru the orfice
11:18 PM rue_mohr: part of my design hangup was weather to switch it @ HP or LP
11:18 PM katsmeow: regulators lose accuracy
11:18 PM * rue_mohr goes for up 4 of tea
11:18 PM katsmeow: just fill a known volume, and then open it's bottom to pour it
11:20 PM Tom_L: snow
11:21 PM rue_mohr: the idea has been in the queue
11:21 PM rue_mohr: but you kinda named one of the hagups,
11:21 PM rue_mohr: I was trying to find a basic water strainer
11:22 PM rue_mohr: you know, for that GrAvEl!?! that ends up in the filter of the kitchen sink tap
11:22 PM rue_mohr: keep it out of the regulator/solinoid
11:23 PM katsmeow: they are made for ice machines
11:23 PM rue_mohr: I bought a strainer for a few bucks from china, but its... huge
11:23 PM rue_mohr: must be for farm irrigation or soemthing
11:23 PM rue_mohr: looked reasonable on the page
11:24 PM rue_mohr: I just need a strainer, but a full blown filter
11:24 PM rue_mohr: that said, if I take it up to hose theread, I can use a washing machine strainer on it
11:24 PM rue_mohr: mmmm I liek that
11:25 PM rue_mohr: mostly having fun trying to make sure that the stuff I get dosn't have leaded brass in it
11:26 PM rue_mohr: I was given the 'system' that sprayed water on the vegitables of the local supermarket for a LONG TIME, but... from what I can tell, it might be leaded brass
11:26 PM rue_mohr: seems to be pneumatic parts
11:26 PM Tom_L: i thought brass was copper and zinc, not lead
11:26 PM rue_mohr: apparently they like to add lead for 'machinability'
11:27 PM Tom_L: and bronze is copper and tin
11:28 PM rue_mohr: https://www.amazon.ca/Washing-Machine-Inline-Water-INLINE-WATER-FILTERS-85470/dp/B0013TM4KQ/ref=sr_1_21
11:28 PM rue_mohr: wtf is with these prices?
11:28 PM rue_mohr: https://www.amazon.ca/Valterra-W1526VP-Hose-Washer-Screen/dp/B002N5LCIY/ref=pd_sim_469_5
11:28 PM rue_mohr: there!
11:28 PM rue_mohr: thats all I want
11:28 PM rue_mohr: $4 for 3 pcs....
11:29 PM rue_mohr: maybe I can get them locally
11:29 PM Tom_L: go to the hardware store for those
11:29 PM rue_mohr: pay the same, get it now
11:30 PM Tom_L: print one
11:30 PM rue_mohr: hahaha
11:30 PM rue_mohr: damn,.....
11:30 PM Tom_L: get some rubberized string
11:30 PM rue_mohr: ... well....
11:30 PM rue_mohr: you might have a workable idea...
11:30 PM Tom_L: print half, lay the screen down, print the rest
11:31 PM rue_mohr: aha
11:31 PM rue_mohr: isle 4
11:31 PM Tom_L: any progress on the can holder?
11:32 PM rue_mohr: were wating for orders, we have stock of 10 of almost everything
11:32 PM rue_mohr: http://www.canadiantire.ca/en/pdp/certified-mesh-filters-4-pk-0593436p.html#srp
11:32 PM rue_mohr: does that link work?? $1 ea 4pk
11:32 PM rue_mohr: thats it
11:32 PM rue_mohr: ok
11:32 PM rue_mohr: so I just need to adapt to hose and back
11:33 PM Tom_L: https://www.amazon.com/Best-Sellers-Health-Personal-Care-Tobacco-Pipe-Screens/zgbs/hpc/10342670011
11:34 PM Tom_L: brass or stainless
11:34 PM Tom_L: 150 / 5.95
11:34 PM rue_mohr: wow, over $1ea from china
11:34 PM rue_mohr: oh, huh
11:35 PM rue_mohr: ok, thats the plan I needed for that, thanks
11:35 PM rue_mohr: thats prolly the last peice for that
11:35 PM rue_mohr: I need to take 1/4" pipe up to hose and back
11:35 PM rue_mohr: thats doable tho
11:36 PM Tom_L: https://www.amazon.com/Everydlife-Crystal-Screens-Diameter-Stainless/dp/B073WQJYRS/ref=zg_bs_10342670011_9/143-9648308-6589633?_encoding=UTF8&psc=1&refRID=KBVVE75BD9QYNNXKMFWC
11:36 PM Tom_L: even fitted
11:36 PM Tom_L: cost more
11:39 PM rue_mohr: ok, I'm good here, it turns out the project box has most of the parts
11:39 PM rue_mohr: I need a male hose to 1/2"NPT and a 1/2NPT to 1/4push-fit
11:40 PM Tom_L: have those
