[00:00:19] <rue_house> http://ruemohr.org/~ircjunk/tutorials/elex/electricMotor/main.html
[00:01:44] <katsmeow> that "3 hp" motor is missng it's brushes, their springs, holder cap, and access plate
[00:02:00] <rue_house> ooo
[00:02:11] <rue_house> threaded plastic caps?
[00:02:34] <rue_house> oh crap PLEASE give me reminders to finish your 7 seg digits
[00:03:03] <katsmeow> not threaded
[00:03:40] <katsmeow> dependng on heating, i can make something, i just haveto spend hours on ebay looking for the right size brushes, springs
[00:03:41] <rue_house> ah, me and moon had to make custom threaded caps for his motors
[00:03:46] <rue_house> I love lathe!
[00:04:01] <rue_house> get oversized ones and shape them down
[00:04:29] <katsmeow> you should mention balancing the rotor on that motor, and using stiff enough wire
[00:04:42] <katsmeow> yeas, filed a lot of brushes here
[00:04:56] * rue_house looks under "B"
[00:06:04] <rue_house> http://ruemohr.org/~ircjunk/tutorials/elex/electricMotor/main.html
[00:06:12] <rue_house> yay, I'm mentally done for the night
[00:06:26] <katsmeow> metoo
[00:06:58] <katsmeow> so moon is a "he"
[00:07:11] <rue_house> yes
[00:07:23] <rue_house> http://www.mymotor.org/
[00:07:30] <rue_house> I like this motor design for kids
[00:07:44] <rue_house> hmmm
[00:07:47] <rue_house> anyhow
[00:09:08] <katsmeow> cute
[00:09:41] <katsmeow> atm, i don't have the energy to go get a slice of pizza out of the nuke box
[00:09:42] <rue_house> the trick is to strip the insulation off just right to commutate it
[00:09:58] <katsmeow> yeas, i saw the folded over pit there
[00:10:00] <rue_house> thats a catch 22
[00:10:01] <katsmeow> Bit
[00:10:09] <rue_house> ah yes
[00:10:13] <katsmeow> it hasto be folded the right direction
[00:10:36] <katsmeow> you could provide a hint or a pic
[00:10:39] <rue_house> the design as I was taught it, required a fluke of balance that would make it jump off the holder at just the right point
[00:10:49] <rue_house> I dont actually know
[00:10:57] <katsmeow> o
[00:11:04] <rue_house> I'd like to say within 45 degrees
[00:11:10] <katsmeow> you shold build one befire the kids get there
[00:11:23] <katsmeow> or, you lbyi86h ;;o byqwkjetlq,jek.bn5in there
[00:11:26] <rue_house> yup
[00:11:32] <rue_house> there is gonna be lots of testing
[00:11:37] <rue_house> I have to make 50 kits
[00:11:42] <katsmeow> 50!?
[00:11:54] <katsmeow> but no one showed up last weekend
[00:11:56] <rue_house> yea, there is gonna be a faire
[00:12:02] <katsmeow> oh, that
[00:12:05] <rue_house> its for a faire
[00:12:07] <rue_house> yea
[00:12:32] <katsmeow> add a wall-type lite switch, have the arm operate it
[00:14:11] <katsmeow> add several lite switches, lable one "hello", so whe toggled, a synth says "hello!"
[00:14:29] <rue_house> heh
[00:14:36] <rue_house> "HELLO" "WORLD"
[00:14:50] <katsmeow> yeas
[00:20:15] <katsmeow> i vividly remember the kitchen scene from Chitty Chitty Bang Bang, 48 yrs ago
[00:20:31] <rue_house> :)
[00:20:58] <katsmeow> it will be 50 yr anniversary in 2018, and STILL no one has a railroad deliver robotically cooked breakfast to the table every morning
[00:21:20] <rue_house> I dont eat at a table
[00:21:39] <katsmeow> i have a wide descripton of "table"
[00:21:45] <rue_house> but I'v been scorning myself for not having a basic kiy roomba
[00:23:08] <katsmeow> kiy?
[00:23:24] <rue_house> diy
[00:23:38] <rue_house> kiy would be kit-it-yourself I suppose...
[00:23:57] <rue_house> I'v known some pretty good kit cars tho ;)
[00:24:10] <katsmeow> happy midnite!
[00:28:26] <katsmeow> i noticed that if i have the house covered in pv panels now, i'd have made no electricity with them this week
[00:29:11] <rue_house> <anonnumberanon> rue_house, define "better"
[00:29:11] <rue_house> <rue_house> better is like a wheel that is actaully, really round, and not square with pillows duct-taped to the flat sides like all the wheels you see currently used
[00:29:27] <rue_house> interesing thing
[00:29:41] <rue_house> in a half-cloudy day, you realize something if you look,
[00:29:49] <rue_house> the clouds are brighter than the clear sky
[00:30:01] <katsmeow> sometimes
[00:30:21] <rue_house> as it turns out, the difraction of cloud means that you get the same amount of power nomatter which way your panels are pointed
[00:30:44] <katsmeow> same amount in this case means not enough to drive the motors doing the pointing
[00:33:50] <katsmeow> clouds coming in from La tomorrow : http://images.intellicast.com/WxImages/Radar/tvr.gif
[00:47:42] <rue_bed2> if I'm teaching someone to weld, do you think its valuable to do some leadwelding to understand the process without the desitractions?
[00:48:13] <katsmeow> leadwelding?
[00:48:26] <rue_bed2> with a soldering gun
[00:48:30] <rue_bed2> lead to lead with lead
[00:49:09] <katsmeow> sure, teach how the metals flow when hot
[00:49:34] <rue_bed2> esp when its all the same material and it all starts to melt at once
[00:50:18] <rue_bed2> and its just a soldering gun, no arc to spook a newb or flashing light or trying to distinguish slag from real metal
[00:50:49] <katsmeow> and how if the base metal isn't melted, and you pile on melted metal, it isn't welded
[00:50:55] <rue_bed2> you ever use the stick to flick excess metal out of a ugly pool?
[00:51:24] <rue_bed2> I hate when it m s
[00:51:32] <katsmeow> if i haveto do that, i haveto grind it anyhow
[00:51:35] <rue_bed2> and wont n
[00:51:57] <katsmeow> n?
[00:52:22] <rue_bed2> when the stick builds up two lumps, one on each piece, but they wont come togethor
[00:52:50] <rue_bed2> prolly not enough current, but its usually right up against risking too much heat
[00:53:17] <rue_bed2> ya know, I'm learing the value of welding CLEAN metal
[00:54:11] * katsmeow nods
[00:54:29] <rue_bed2> I think rust ~3x the slag volume
[00:54:57] <katsmeow> and al that flucks on the rod
[00:55:28] <rue_bed2> 6011 is mid-flux isn't it?
[00:55:50] <rue_bed2> stainless is less and .... something is much more...
[00:55:56] <katsmeow> the 60xx is splattery too
[00:56:07] <katsmeow> i use only 7018
[00:56:20] <rue_bed2> 7018 isn't stainless?
[00:56:22] <katsmeow> but it's hot, 60xx is colder
[00:56:26] <katsmeow> no
[00:56:43] <rue_bed2> oh, isn't 6011 best for mild steel?
[00:56:54] <rue_bed2> 7018 being harder?
[00:57:20] <katsmeow> if you are welding with 7018 and pass over a 60xx weld, the 60xx will flow out like water
[00:57:44] <rue_bed2> yea, like brazing over solder,
[00:58:10] <rue_bed2> but my impression was that if you use to high grade a rod, you get joints stronger than the base material
[00:58:10] <katsmeow> 60xx is prolly easier on thinner metals
[00:59:21] <rue_bed2> is 7018 almost no slag?
[00:59:42] <katsmeow> the slag stays on the bead, and not all over creation
[01:00:18] <rue_bed2> 6011 dosn't give me much spatter
[01:00:28] <katsmeow> get a few sticks, 1/8 for 110amp and 3/32 for 90amp , try it out
[01:00:38] <rue_bed2> if I were trying to spatter something to death, I'd use the core-flux mig
[01:00:45] <katsmeow> i am all outa 3/32 atm
[01:00:59] <rue_bed2> I use the smallest stuff usually
[01:03:53] <rue_bed2> the led strips in my room
[01:04:39] <rue_bed2> I THKINK so many of them are in parallel, that the ambient light from the laptop and the hall light up 4 of the most sensitive ones when they are all powered off
[01:07:00] <rue_bed2> maybe its the wifi, thats a scarry thought
[01:07:11] <katsmeow> powerful rf
[01:08:20] <rue_bed2> its 6 of the leds, dont go completely out when the supply is off
[01:10:52] <katsmeow> are you SURE the psu is off?
[01:24:43] <katsmeow> ..........................
[21:56:30] <katsmeow> umo is selling piles of HM628128 and HY628100 , in different packages, they are essentially the same chip, but poeple are *wanting* those slow 70ns and 85ns chips, they have *SUPER-LOW* powerdown levels, like 10uw at 3.3v
[21:59:32] <katsmeow> smd 2n2955 : 7050 PCS MOTOROLA MJD2955 INTEGRATED CIRCUITS
[21:59:52] <katsmeow> great deal, not bidding
[22:05:43] * katsmeow would use them to yank the mosfet p-chan gate off during overcurrent events
[22:20:15] <katsmeow> bids went up 10x on those 2955's : Current bid:
[22:20:39] <katsmeow> so much for bottom feeding, it's beenbrutal today
[22:29:09] <katsmeow> i wonder how fast a golfball can fly before the heat starts to break it down
[22:59:16] <zhanx> Pump went out while at work :(
[23:00:44] <katsmeow> smog pump? truck water pump? house water pump? aquarium pump?
[23:00:56] <zhanx> House water
[23:01:08] <katsmeow> that can be annoying
[23:01:25] <zhanx> Worked new job and dirty no water
[23:01:30] <katsmeow> above ground or down in a well?
[23:01:43] <katsmeow> maybe it's full of ice and ha not exploded yet
[23:01:46] <zhanx> Landlord was not helpful
[23:01:58] <zhanx> Above ground
[23:02:06] <katsmeow> LL = father-n-law?
[23:02:19] <zhanx> No
[23:02:27] <zhanx> I wish
[23:02:43] <zhanx> Landlord is lee, Lee thinks he is smart
[23:02:55] <zhanx> Lee is a janitorial man
[23:03:05] <katsmeow> 24-hr ,, damn, walmart woldn't have one, HomeDepot or Lowes will
[23:03:45] <zhanx> Nope I got tools amd stuff, waiting on drying time
[23:04:16] <katsmeow> tools are fine, but if yu need a pump, they don't really help you wash off
[23:04:31] * zhanx watches paint dry basically
[23:04:52] <zhanx> No I am mostly sure it's fixed now
[23:05:00] <katsmeow> o
[23:05:10] <zhanx> But sealant take time to dry
[23:05:31] <zhanx> P for plenty and new o-rings I got lucky
[23:05:55] <katsmeow> i use 3 sealants any more: vaseline, permatex #2, or 5-minute epoxy
[23:06:37] <zhanx> He used tar in it :(
[23:06:53] <zhanx> Took forever to clean up
[23:06:55] <katsmeow> tar isn't drinking grade
[23:07:57] <zhanx> I know
[23:08:12] <zhanx> I am charging him for this
[23:08:13] <katsmeow> for instance, i use vaseine on the o-rings for the water filters
[23:08:21] <katsmeow> as little as possible
[23:08:40] <zhanx> Oh I am charge 400 to fix this pump
[23:08:50] <katsmeow> i mean as little vaselie
[23:09:09] <zhanx> K
[23:09:24] * katsmeow vaselines the car door gaskets for winter too, beats silicone spray
[23:09:51] <zhanx> And don't freeze right?
[23:09:55] <rue_shop3> hey
[23:10:04] <zhanx> Rue
[23:10:08] <rue_shop3> well, got some work done on the potato planters
[23:10:28] <zhanx> Potatoes are mammals
[23:10:45] <zhanx> You can't eat them
[23:10:49] <katsmeow> how does one work on potatoe planters?
[23:11:11] * katsmeow looks at rue's raised garden beds
[23:11:14] <zhanx> Tires in a stack?
[23:11:39] <rue_shop3> place planters, install potatoes and dirt
[23:12:15] <katsmeow> but you placed the concrete-edged raised beds for tatoes, didn't you?
[23:12:33] <rue_shop3> no
[23:12:41] <rue_shop3> those are for the good stuff
[23:12:42] <katsmeow> oh
[23:12:52] <rue_shop3> I have stackable organic wood ones for the potatoes
[23:12:55] <katsmeow> tatoes are good, i eat them
[23:12:55] <zhanx> So new job todsy
[23:13:04] <katsmeow> YAY!!!
[23:13:11] <katsmeow> doing what?
[23:13:14] <zhanx> Kind of
[23:13:25] <zhanx> Diesel engine tech
[23:13:42] <zhanx> New boss likes to watch over my shoulder
[23:13:47] <rue_shop3> oh great
[23:14:03] <rue_shop3> you didn't turn that enough, did you mark this one?
[23:14:12] <rue_shop3> did you do this that way?
[23:14:19] <katsmeow> that bolt goes here, this one goes there
[23:14:22] <rue_shop3> dont forget to do that
[23:14:25] <zhanx> Like he is short so he pulled up an old rim to be taller than me
[23:14:35] <rue_shop3> hehe
[23:14:37] <zhanx> To stare over my shoulder
[23:14:46] <rue_shop3> your definition of short is prolly 6'
[23:15:08] <zhanx> Then he left and called I said x is bad, did you time it, nope
[23:15:19] <zhanx> 5 minutes later he was back
[23:15:38] <zhanx> I already had it torn down etc
[23:15:47] <katsmeow> don't punch this one out
[23:16:05] <zhanx> I will try not to
[23:16:10] <rue_shop3> did he have you working on a breakdown or a maintenance
[23:16:25] <zhanx> Breakdown ,
[23:16:26] <katsmeow> oil change
[23:16:29] <katsmeow> lol
[23:16:42] <zhanx> The power steering pump ripped out
[23:16:51] <rue_shop3> oh, not the engine then
[23:17:09] <zhanx> On detroit diesel they are bolted to the engine
[23:17:26] <zhanx> It took out part of the engine on its way
[23:17:30] <rue_shop3> accessories usualyl are,aren't they?
[23:17:39] <rue_shop3> !?
[23:17:41] <katsmeow> everything on my dieasle is bolted to the engine, except the serpentine adjuster
[23:17:49] <zhanx> Yes but detroit are gear driven
[23:17:53] <rue_shop3> oooh
[23:17:58] <rue_shop3> ugly
[23:18:06] <zhanx> Very
[23:18:13] <rue_shop3> did it kill its gears?
[23:18:28] <zhanx> Actually no, I was surprised
[23:18:46] <zhanx> But the block might be tweak
[23:19:03] <katsmeow> shafts twist before gears break, usually, tho i have busted teeth off gears in a differential
[23:19:15] <katsmeow> broke the bell housing
[23:19:32] <zhanx> Detroit is valve cover, head, inspection area, block
[23:19:46] <zhanx> Oil pan etc
[23:20:25] <zhanx> I can see a gasket that is normally in the block
[23:20:39] <rue_shop3> this is the second week I'v had to put my robot arm away with almost nothing new done on it
[23:20:49] <zhanx> Paint it
[23:21:04] <rue_shop3> cleaning up shop for kids robotics tommorow
[23:21:24] <rue_shop3> all the projects have to go away, and all the materials, and walkways need to be re-established
[23:21:34] <zhanx> Good idea. My wife signed me up to be a cub master for boyscouts
[23:22:02] <katsmeow> twisted off an oil pump driveshaft 2x, not my fault, block needed hot tanking, been run for 20 yrs on non-detergent *motor* oil, then they put detergent *engine* oil into it
[23:22:21] <zhanx> Asking for issues there kat
[23:22:34] <katsmeow> yea, i got rid of it asap
[23:22:53] <katsmeow> needed a complete teardown and cleaning
[23:23:06] <zhanx> Thursday I go for my new york inspection license
[23:23:30] <zhanx> After that I can open my own business
[23:24:29] <katsmeow> err, i wouldn't quit the new job next week already :-|
[23:24:43] <zhanx> I figure with my pstd issues etc . I should start the proc
[23:24:52] <zhanx> I wouldn't
[23:25:39] <zhanx> But I contract after that
[23:26:23] * katsmeow nods
[23:27:01] <zhanx> I have paid a ton for certifications the last couple of weeks
[23:27:26] <zhanx> 6 more tests and I am master diesel tech
[23:27:45] <katsmeow> i went to store for groceries, heard a god bark, i froze, turned slowly after a minute, located the god, did a threat assessment, etc etc
[23:28:34] <katsmeow> jobs pay for certs and the frames to hang them up in
[23:28:47] <zhanx> Or my own business
[23:29:00] <zhanx> And both i guess
[23:29:21] <katsmeow> don't dismiss the business contacts in the community by having an outside job
[23:30:39] <zhanx> Ok brb testing pump
[23:30:52] * katsmeow crosses some fingers
[23:35:18] <zhanx> I have water
[23:35:27] <katsmeow> yay!
[23:35:46] <katsmeow> what had caused it to quit?
[23:35:47] <zhanx> Need yo check for leaks still
[23:35:56] <zhanx> Landlord fixed it
[23:36:16] <katsmeow> err, umm, ok
[23:36:48] <rue_shop3> http://www.aliexpress.com/item/14-Pin-Male-Plug-136961-141162-Miller-Hobart-Welding-Wire-Feeder-Foot-Control/32605945309.html
[23:36:53] <rue_shop3> look what I found this week!
[23:36:58] <rue_shop3> I'm so happy
[23:37:08] <rue_shop3> I can make a control pedal for my welder for less than $600
[23:38:09] * katsmeow hands rue a sewing machine pedal
[23:38:32] <rue_shop3> tis, ok, I found an industrial pedal too
[23:38:37] <rue_shop3> $20usd
[23:39:31] <katsmeow> every year when yu haveto rebuild that cable/connector, you'll wish it was 2-conductor serial or wireless
[23:39:56] <rue_shop3> its a $3000 welder, I'm not gonna modify it
[23:40:14] <zhanx> No leaks
[23:40:14] * katsmeow hands rue a DB-9 and a DB-13
[23:40:21] <rue_shop3> no!
[23:40:25] <rue_shop3> $3000
[23:40:37] <katsmeow> $3000 !?! , you know i weld with a $300 welder?!?
[23:41:00] <rue_shop3> it takes everything from 120 single phase to 480 3 phase, auto. its a 200A welder
[23:41:04] <rue_shop3> tig/stick
[23:41:08] <katsmeow> AND, i had to put in the decenet set of diodes and fan and heatsink etc etc???
[23:41:31] <rue_shop3> its a miller maxstar 200 SD
[23:41:56] <katsmeow> but you never welded before, you never used anything but 60xx rod, .............................................. arg
[23:41:56] <rue_shop3> it should be the last welder I will ever need
[23:42:35] <katsmeow> mine is a miller too, i bought it ~1980
[23:42:44] <rue_shop3> mine weighs 40 lbs
[23:42:48] <rue_shop3> inverter welder
[23:42:49] <katsmeow> no, 88
[23:43:21] <zhanx> I want a welder
[23:44:00] * zhanx get a shower now
[23:44:23] <katsmeow> yanno, i weld something almost every day, with the cheapest Miller growlbox they had at the time, almost 30 yrs ago

[23:44:48] <rue_shop3> geez google!
[23:45:14] <katsmeow> i could really use hv arc stabilization, remote operation, etc
[23:45:27] <katsmeow> https%3A%2F%2Fwww.millerwelds.com%2F~%2Fmedia%2Fmiller%2520electric%2Ffiles%2Fpdf%2Fliterature%2520ordering%2520form%2Ftig%2Fdc32-0.pdf
[23:45:35] <katsmeow> you need better browser plugins
[23:46:03] <rue_shop3> part of the choice was that its 100% duty is good for the largest thing I'd uaully do
[23:46:07] <zhanx> Yeh my http://www.amazon.com/Sunchang-Ssamjang-Doenjang-gram-Combo/dp/B01035ZFJW?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00 wil be here Monday
[23:47:07] <katsmeow> i have burned at 110 for hours before on mine, i have never needed more than 130a on 1/8 rod for anything
[23:47:25] <zhanx> Need to bleed all the dirt out now :(
[23:47:27] <katsmeow> i am talking 30+ feet of bead in one burn
[23:48:22] <zhanx> Kat that is really really good
[23:48:22] <rue_shop3> 125A, continious
[23:48:38] <rue_shop3> most of my welding tops out at 55
[23:49:04] <rue_shop3> 90A cuts most stuff I'm trying to punch holes in
[23:49:19] <zhanx> Yea think
[23:49:48] <katsmeow> if you are cuttng with a welder, you need a plasma torch
[23:49:59] <rue_shop3> just the occasional hole
[23:50:01] <zhanx> Today I learned rue thinks his welder is a plasma cutter
[23:50:06] <rue_shop3> like round holes in water tanks
[23:50:14] <rue_shop3> easier to use scrap stick and 90A
[23:50:33] <katsmeow> on .030 steel?
[23:50:42] <katsmeow> try 1/4 or heavier
[23:50:43] <rue_shop3> its a garunteed cut
[23:51:00] <katsmeow> not a guaraneteed placement tho
[23:51:16] <rue_shop3> sometimes I get surprises on what it takes to burn thru a peice of plate
[23:51:26] <rue_shop3> the holes can be a bit wiggly
[23:51:34] <rue_shop3> sofar its not mattered
[23:51:47] <rue_shop3> and, you get a reinforced edge bead :)
[23:51:55] <katsmeow> the glass on the inside of water heater tanks can seriously mess up a hot cut operation
[23:53:04] <rue_shop3> 180m for $12
[23:53:15] <rue_shop3> or 18m for $2.55
[23:53:37] <zhanx> Rue will you eat this?
[23:53:43] <zhanx> http://www.amazon.com/Anchovy-Fish-Sauce-2-2-Chung-Jung-One/dp/B00TCOAXR0?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00
[23:53:47] <rue_shop3> no
[23:53:53] <katsmeow> 180m of what?
[23:53:54] <rue_shop3> I dont eat anything fish
[23:54:02] <rue_shop3> tiger tail beading wire, 0.8mm
[23:54:05] <katsmeow> o
[23:54:10] <rue_shop3> its plastic coated stainless
[23:54:14] <katsmeow> yeas
[23:54:20] <katsmeow> i has some
[23:54:44] <katsmeow> was afraid the plastic wold deform and change the lengths over the pulleys
[23:54:46] <rue_shop3> I think before it was used in beading it was used for drive line in plotters
[23:55:01] <katsmeow> and fishing leaders
[23:55:09] <rue_shop3> depends on force, I'm collecting things to see whats gonna work
[23:55:19] <katsmeow> overall it's good stuff if you don't need limp flexability
[23:56:49] <rue_shop3> 100m of green for $21
[23:57:14] <katsmeow> color-coded tendons
[23:57:20] <rue_shop3> 180m is almost too good a deal
[23:57:47] <katsmeow> finger tips in gree, mid-bones in yellow, roots in red, laterals n black, etc
[23:57:59] <rue_shop3> colours are pricey
[23:58:10] <katsmeow> ok
[23:58:11] <rue_shop3> they have pink and green
[23:58:17] <rue_shop3> both tones suck
[23:59:43] <rue_shop3> oh the 2.55 roll is 'zink alloy'
