00:04 yahweh_ Rue_mohr!
00:05 yahweh_ C'mon man it's not even 10 yet. what are you doing in bed?
00:06 yahweh_ I may have found you a lathe man.
00:15 rrywolf needs a lathe
00:31 yahweh_ Sorry furrywolf Rue needs it most.
00:32 yahweh_ without it he cannot robot to his full potential.\
00:33 furrywolf I need to cnc-ify mine... I'm missing the threading gearbox, but if I convert it to cnc, and add a stepper driver for the spindle instead of the stock motor, I should be able to cut threads without one...
00:33 furrywolf presumably emc2 can handle cutting threads.
00:33 yahweh_ threading things that a tap can't handle?
00:35 furrywolf taps are expensive and you need one for every size... and sometimes you need odd sizes, like one part I might make that has threads around 3" diameter but ~14tpi...
00:36 furrywolf maybe finer. been a while since I looked at it.
00:36 yahweh_ lathes are pretty expensive too...
00:37 yahweh_ Ask rue about his cnc machine.
00:37 furrywolf I have one, it's just... inadequate.
00:37 furrywolf and somehow none of the spam I get is for enlarging my lathe. :)
00:38 yahweh_ it can operate with the z axis as a cylinder.
00:38 yahweh_ you get spam?
00:39 yahweh_ sweet, found my other hand.
00:39 furrywolf of course. you don't?
00:39 yahweh_ No, never.
00:39 yahweh_ not in years.
00:40 yahweh_ Anyway, rue's cnc machine is a homebrew and it can have a rotating z axis so he can carve cylindrical objects.
00:41 yahweh_ or just normal ones.
00:41 yahweh_ Might be worth it for you to try and copy it.
00:41 furrywolf I need to rig up a 4th axis for my mill. I have a rotary table, and a bracket to mount the rotary table across the bed, and a chuck that bolts to the rotary table, but need to cncify the rotary table...
00:42 yahweh_ It's made out of what appears to be crap, but it works.
00:43 yahweh_ modding a milling machine?
00:43 yahweh_ I wish I had a milling machine. :(
00:44 furrywolf I have one, it's just... very small.
00:45 yahweh_ I have none, it's even smaller.
00:46 furrywolf http://www.irritatedvowel.com/Railroad/Workshop/pmb_sherline_rotary_table_with_abs_rod.jpg I have that rotary table, the problem is mine is manual, no stepper mount. need to fab up a stepper mount for it.
00:48 furrywolf sherline's website insists you can't mount a stepper to the manual version, but I don't see any particular reason why you can't other than them wanting to make more money.
00:52 yahweh_ That's usually the case.
00:52 yahweh_ I'm not the one to ask however.
00:52 furrywolf what is usually the case?
00:53 furrywolf that you can mount a stepper to anything? heh
00:55 yahweh_ No, that they probably just want more money.
01:00 furrywolf http://www.sherline.com/3700pg.htm "The rotary table is now also available with a stepper motor mount attached ready for the application of a stepper motor and CNC controls. See P/N 3700CNC. Please note that it is NOT possible to upgrade a manual P/N 3700 rotary table to a P/N 3700-CNC later on. To maintain the required degree of accuracy, the base of the rotary table and the worm housing are ground as a pair in the production process.
01:00 furrywolf It would not be possible to maintain this level of accuracy if a CNC worm housing were to be bolted to a table for which is was not specially ground. While kits are available to convert any Sherline lathe or mill to CNC stepper motor mounts, no such kit is available for the rotary table. A new unit must be purchased."
01:01 furrywolf or you can fab your own bit, methinks.
01:02 yahweh_ probably
01:03 yahweh_ aw hell, just build a 3d printer. :)
01:03 furrywolf ... useless.
01:03 furrywolf I make things out of real materials.
01:03 furrywolf show me 3d printing tool steel, and I'll make one. :P
01:04 rrywolf listens to some Raveonettes, and decides they're good enough to get mor
01:07 furrywolf if worst comes to worst, I can just mount a flat plate to the back of the table, mount a stepper to the plate, and use a shaft coupler.
01:07 furrywolf in fact, that's probably the best way... no mods to the table to screw up. :)
01:17 yahweh_ yeah, modding can be risky business.
01:18 rrywolf curls up on katsmeow-afk for bed
01:20 furrywolf :(
01:21 rrywolf curls up on any09190765 for bed
01:58 y09190765 looks curled u
06:14 rue_mohr I woder what he found
06:15 rue_mohr I need to implement flea control :/
07:23 katsmeow-afk he who what?
07:24 katsmeow-afk do i really want a permeate pump?
07:24 katsmeow-afk do you want a permeate pump?
08:23 katsmeow-afk As home prices are slowly edging up in various parts of the country, the housing slump may be reaching its end, which may be good news for the owners of the town of Pray, Mont.
08:23 katsmeow-afk The town is available for sale through Internet bidding and will have a live auction on Wednesday at 6:30 p.m. mountain daylight time. The minimum starting bid is $100,000.
08:27 katsmeow-afk http://www.ucshobeauction.com/property.aspx?item=99999&agency=25065
08:31 katsmeow-afk Henry River Mill Village, N.C., is on sale for $1.4 million after being used as the set of the downtrodden community of District 12 in the film "The Hunger Games." Wade Shepherd, 83, is selling the 72-acre property, with 22 buildings.
08:31 katsmeow-afk On sale for $2.5 million, the town of Toomsboro, Ga. is about halfway between Atlanta and Savannah. David Bumgardner, a developer in south Georgia, is trying to sell 28 properties in the town, which has 700 residents.
08:32 katsmeow-afk The French village of Courbefy, 280 miles southwest of Paris, was up for auction in February for an asking price of $400,000, or 300,000 euro, but no one bid. But an American buyer bought the property for about $649,594, (520,000 euro), from the French Bank Credit Agricole. The stupid american paid $250,000 more than asking price, even tho no one else wanted the place!
08:33 katsmeow-afk Called "the nation's smallest town" at about 10 acres, Buford, Wyo. was auctioned on April 5 for $900,000.
08:49 rue_mohr *Buyer agrees to pay on auction day, non-refundable earnest money of $50,000, by certified check, made payable to United Country - Shobe Auction & Realty.
08:49 rue_mohr $50000 to play
09:00 katsmeow-afk says the buyer does, not bidders
09:00 rue_mohr also says they have to pay in cash when they win
09:01 rue_mohr is Johnny worth enough? can I just give them him?
09:01 tsmeow-afk is un
10:29 furrywolf there's a couple local towns here perpetually for sale.

13:58 rue_mohr "borax is for smelter, please stop using for laundry"
13:58 katsmeow-afk right
13:58 katsmeow-afk got to stick with prioritoes
13:59 myself rue_mohr: photo of note/sign?
14:00 tsmeow-afk would ask why she is so tired, but worried about that kleenexbot coming back ins
14:05 rue_mohr http://slimber.com/index.php?image=thing.g194717
14:06 rue_mohr ^^ kat can you do flash for me?
14:07 katsmeow-afk "do" it?
14:07 rue_mohr I know you lik to keep it off
14:07 rue_mohr I drew you a schematic
14:08 katsmeow-afk o
14:08 katsmeow-afk i do not see how that autoadjusts the decimal
14:08 rue_mohr it does automatically
14:09 rue_mohr anything over 9.99 is displayed as xx.x
14:10 rue_mohr there is a play button at the bottom you can press to see how I drew it
14:10 katsmeow-afk by cycling 0,1,2 into the bottom A of the rom ?
14:10 rue_mohr thats the digit strobe
14:10 rue_mohr the 10 bits inheritly contain the decimal point
14:11 katsmeow-afk well, yeas and no
14:12 katsmeow-afk i inherently know how i want it displayed, but there's noting in 987 or 1010 that says where the decimal point is
14:12 rue_mohr 0-1023
14:12 rue_mohr every value maps to a voltage
14:12 rue_mohr and there is a fixed method for drawing every voltage on the 7 segs
14:13 rue_mohr the rom contains, for each 10 bit value, the segment and decimal place data for each display
14:13 rue_mohr you just have to strobe thru them
14:13 rue_mohr it takes care of the rest
14:14 rue_mohr think of it like a single character on a raster display
14:14 katsmeow-afk i think the rom would need to be huge, and the avr would still need to know how if to display .7 or 7. or 7
14:14 rue_mohr you put int eh ascii code, and tell it what column, and it putouts the pixels
14:14 rue_mohr no 4k rom would do it
14:14 tsmeow-afk thinks you are reinventing the 74
14:15 rue_mohr no, this does all the binary conversion and decimal placing for you
14:15 katsmeow-afk i don't follow ow
14:15 katsmeow-afk how
14:15 rue_mohr hmm
14:15 katsmeow-afk you would haveto drive another 2 bits into the rom
14:16 rue_mohr thats the 2 at the bottom
14:16 rue_mohr they do the strobing
14:16 katsmeow-afk oh,, i don't think "selecton" when you say "strobing"
14:17 rue_mohr yea, they work out what digit is being displayed
14:17 rue_mohr aka 0, 1, 2, 0, 1, 2
14:17 katsmeow-afk ok, i get it, but there is still a size problem, isn't there?
14:18 katsmeow-afk you need to store .7 , 7 , and 7.
14:18 katsmeow-afk and 1. , 1, and .1
14:19 katsmeow-afk hmm
14:19 katsmeow-afk fancy programming
14:19 rue_mohr just 0.00 to 9.99 and 10.0 to 15.0
14:19 tsmeow-afk shakes rue's
14:20 katsmeow-afk rue, your paw is shaking
14:20 e_mohr participates in the s
14:20 e_mohr lets confused and wonders how long this goes
14:21 tsmeow-afk suggests a countdown to
14:21 rue_mohr on 0 or after?
14:21 rue_mohr or on 1
14:21 rue_mohr should we flip a coin to decide?
14:21 rue_mohr are you heads or am I?
14:21 katsmeow-afk i can't flip coins while shaking
14:22 rue_mohr well, this is a problem isn't it.
14:22 rue_mohr rock-paper-scisors is out of the question...
14:22 rue_mohr I see, with my little eye, something light beige
14:23 katsmeow-afk a VW !
14:23 rue_mohr aha, ! no, its a computer!
14:24 katsmeow-afk holy cows, click on the play button on this one http://slimber.com/index.php?image=tears.g190084
14:27 katsmeow-afk mighty active pencil!
14:28 katsmeow-afk if only i cold move like that irl
14:28 rue_mohr it goes faster than it went
14:29 rue_mohr bye
14:29 rue_mohr I'm off to school
14:29 katsmeow-afk have funs
14:29 katsmeow-afk do not forget : learn things
15:01 katsmeow-afk or, do not learn to forget things
15:02 katsmeow-afk do learn to not forget things
15:02 ShH reboots katsmeow

19:41 katsmeow-afk i wonder if they can turn the cameras around to see the spacecraft themselves,,, i'd like to know how the paint has held up to the radiation, because if it has, then maybe that's the best non-fade paint for buildings on earth
19:47 Tom_itx speaking of cameras...

20:03 yahweh_ Rue_mohr
20:03 yahweh_ oi oi oi
20:04 katsmeow-afk he may not be back for hours yet
20:04 yahweh_ but he should be at home by now:(
20:04 katsmeow-afk how do you figure that?
20:04 yahweh_ I guess I'll use the damned phone.
20:05 yahweh_ 'Cause he usually finishes work at five.
20:05 yahweh_ it's almost six.
20:05 katsmeow-afk but he isn't at work, work wasn't happening today
20:05 yahweh_ ?
20:05 yahweh_ is it his schooling day thing?
20:05 katsmeow-afk that's what he said it was
20:06 yahweh_ I thought it was thursday.
20:06 yahweh_ How could I be so out of the loop?
20:06 katsmeow-afk it's the current planetary alignment
20:07 katsmeow-afk the loop is off to the left of where you are
20:07 yahweh_ So the universe truely is against me.
20:08 katsmeow-afk only the part controlling the loop part
20:08 katsmeow-afk and it's not *consciously* against you, it's just leaning diffeently today and didn't see you there
20:09 katsmeow-afk it told me so
20:10 yahweh_ Well the next time you speak to the universe kindly tell it to bugger off for me.
20:10 katsmeow-afk again with the sex terms <sigh>
20:12 yahweh_ That wasn't sexual.
20:13 katsmeow-afk to bugger is
20:13 katsmeow-afk what action does that verb signify to you?
20:14 katsmeow-afk let me help you : http://www.google.com/search?q=define%3Abugger
20:26 tsmeow-afk tests your ability to think (perhaps you are an Ai), by pointing you at the uk food "bangers and mash", and see if you can explain why "gangbanger" has nothing to do with guns or making n
20:33 ace4016 i didn't know #robotics was hosting orgies >_>
20:34 tsmeow-afk congrats o
20:34 ace4016 :(
20:34 ace4016 different guy
20:34 tsmeow-afk congrats
20:34 katsmeow-afk oh, right, we had that discusson already
20:35 katsmeow-afk ;-)
20:35 ace4016 lol
20:52 GuShH katsmeow-afk: thoughts on cheap air compressors?
20:52 katsmeow-afk "wear out fast"
20:52 ace4016 lungs
20:52 ace4016 >_>
20:53 GuShH well, I can't afford a belt driven 200L tank.
20:53 katsmeow-afk you didn't mention "tank" , you said "compressor", and didn't mention pressure or volume or hp
20:53 GuShH the tiny 50L ones are 2.5HP
20:53 GuShH direct drive
20:53 GuShH noisy, crappy.
20:54 katsmeow-afk want real cheap? get a fridge compressor, trap the oil coming out the presuure side and route it back to the intake
20:54 GuShH meh, the recovery rate would be sad.
20:54 katsmeow-afk it's low volume, let it run a while, but very high pressure (by shop air standards)
20:55 GuShH I'd rather turn one into a vacuum pump
20:55 katsmeow-afk cheap tank: scrap pipe, weld caps over the ends
20:55 GuShH thought about it, couldn't really source the parts cheap.
20:55 katsmeow-afk cheap 50psi tank: recycled hot water heater
20:55 Tom_itx my thoughts are in my garage
20:55 GuShH by the time you bought the fittings, etc. it costs just as much.
20:56 Tom_itx 5 hp 80 gal
20:56 katsmeow-afk yipes
20:56 Tom_itx 170 psi
20:56 GuShH that's massive.
20:56 katsmeow-afk whatever for?
20:56 GuShH is it a vertical tank at least?
20:56 Tom_itx kat, it blows
20:56 GuShH two or three phase?
20:56 Tom_itx 2 stage pump
20:56 Tom_itx 220v
20:57 tsmeow-afk prefers horiz tanks: lower center of gra
20:57 GuShH 5HP in one phase eek
20:57 GuShH katsmeow-afk: but vertical works nicely in places where you don't have space for a massive chunk of steel
20:57 GuShH and you can chain them
20:57 katsmeow-afk 5hp on 230vac is under 20amps tho
20:57 GuShH it's not the kind of thing I'd want to run on a single phase
20:58 Tom_itx it works fine
20:58 katsmeow-afk but it's less of aload than a air conditioner, if it has an unloader on it
20:58 Tom_itx and vertical takes less room
20:58 Tom_itx and it does kat
20:58 katsmeow-afk Tom is a smart cookie
20:59 GuShH the only way I could get one of those is to get it used and cheap, probably with rust.
20:59 katsmeow-afk GuShH, hence, you build it from scraps
20:59 GuShH couldn't possibly justify a new one since I wouldn't use it professionally
20:59 katsmeow-afk got a baby car engine?
20:59 GuShH no
20:59 katsmeow-afk 2cyl bike engine?
21:00 GuShH having car engines around is a thing of ghetto australia and the us apparently...
21:00 katsmeow-afk heck,, a motor and a dead gas weedwhacker?
21:00 katsmeow-afk car engines have goten real pricey and when you need one, you need one
21:00 GuShH katsmeow-afk: converting a 2 cyl would be nice...
21:00 GuShH one pumps, the other drives.
21:01 GuShH but no, I don't have any.
21:01 katsmeow-afk 2cyl is real rough running, but easy and possible
21:01 katsmeow-afk i've seen kits for converting 6 and 8 cyl car engines
21:01 furrywolf it's good to have spare car engines sitting around. then when you need one, you have one.
21:01 GuShH funny enough old compressors have been converted into hit and miss engines too
21:02 tsmeow-afk
21:02 katsmeow-afk you need low volume, low pressure, or what?
21:02 GuShH high both.
21:03 katsmeow-afk oh, that lets out a water piston and plastic pipe
21:03 GuShH mainly for sand-blasting and sanding, the rest is lowish volume
21:03 katsmeow-afk well, you know the ways to go about that now
21:04 furrywolf also, "<GuShH:#robotics> the tiny 50L ones are 2.5HP" no, they're not... they're 0.5hp, and some marketing type decided input voltage * locked-rotor current = hp...
21:04 katsmeow-afk what furry said
21:05 katsmeow-afk or as HF motors are rated: whatever you want the nameplate to say , that's what they'l make it say ,, and 30 sec later the plastic fan is melted and running out the meager air intakes
21:05 furrywolf I have a 5hp shopvac. if I remember right, it pulls 7A at 115V. :)
21:06 GuShH furrywolf: I'm quoting what the ads say.
21:06 furrywolf it's a "genuine" craftsman, too.
21:06 furrywolf GuShH: don't buy from any brand that publishes numbers like that.
21:07 GuShH they all do because it's the same chinese crap, rebranded.
21:07 furrywolf yes.
21:07 GuShH I've also seen a weedwacker branded as 50cc when it was 26cc
21:07 furrywolf this doesn't change what I just said. :)
21:07 GuShH naturally the price was the same
21:07 furrywolf real brands publish real numbers.
21:07 GuShH you don't get real brands her.
21:08 GuShH here.
21:08 furrywolf heh, I found out this morning I had fake wire.
21:08 GuShH I've seen "michelin" and "hyundai" air compressors, they were the same chinese ones they sell everwhere with other brands.
21:08 furrywolf my 16 gauge cigarette lighter extension cord broke. I grabbed a photo... I'll see if my connection is working well enough to upload it.
21:08 GuShH just saw a 25L 2HP one...
21:09 furrywolf I don't think my connection is, but I'll try.
21:09 katsmeow-afk Southwire was once famous for broken wire, you got 250ft in a roll, but it wasn't in one continuous length of copper under that insulation
21:09 furrywolf lol, I got a roll like that. don't remember who made it.
21:09 katsmeow-afk they said they were right in selling it that way too
21:10 furrywolf I used it to wire up the tach signal in my truck, and it didn't work. took me a while to figure out the problem was the brand fucking new wire I ran had no continuity...
21:10 katsmeow-afk i knew someone who worked for them in later years, he said you were lucky if 12-3 had 3 wires
21:10 furrywolf lol
21:14 furrywolf http://fw.bushytails.net/fakewire01.jpg geee, <insert stereotypical chinese name>, this insulated #20 wire is about the same thickness as bare #16... I bet we could feed it back through the insulation machine!
21:15 katsmeow-afk yep
21:15 furrywolf this is not the first time I've gotten fake wire.
21:16 furrywolf I have a length of "4 AWG ULTRA HIGH POWER" car audio cable, that is quite distinctly #8 with a quarter inch of insulation.
21:16 katsmeow-afk "wow, this is some very lightweight battery cable! oh,, it's got .2 inches of THW insulation on it ..... it's only #12 copper under all that!"
21:16 katsmeow-afk yep, been there
21:16 furrywolf yep. heh.
21:16 furrywolf it says 4 awg, 4 gauge, etc all over it in big letters. it's 8 gauge.
21:17 katsmeow-afk wanna hear something that's bloody dangerous and yet enshrined in the NEC? "4-0 aluminum SE is good for 200amps"
21:18 furrywolf I guess it's to match the wattage rating on the amplifiers it's used with. :)
21:18 katsmeow-afk you pull 200 amps thru it for an hour and you'll burn the skin off your paws if you touch it
21:18 furrywolf if a 2000W amplifier is only 400W, it's perfectly acceptable for you 4 awg power cable to be 8 awg...
21:18 Tom_itx they should have extruded it with fins
21:18 furrywolf 4-ought? that's pretty thick wire.
21:18 katsmeow-afk it is
21:19 furrywolf should be able to handle 200A...
21:19 katsmeow-afk and Al has 4x(?) the resistance of Cu
21:19 furrywolf I thought is was less of a difference than that? I haven't worked with alu much. hate the stuff.
21:20 katsmeow-afk the NEC uses 700cm/amp (which runs hot) and then used a hidden duty cycle for residential use
21:20 katsmeow-afk and then the Al heats up so much more vbecause it has a higher resistance
21:21 furrywolf I know 4/0 copper can take 200A (and a lot more) all day, but have never tried with aluminum.
21:21 katsmeow-afk but i tested it one day, 190amps for 30 minutes and then i got worried the parts thru the studs might catch fire because of lack of airflow to cool it
21:21 katsmeow-afk the breaker box didn't fare well either
21:22 katsmeow-afk the main breaker, a beast of a breaker, did fine, but the buss bars got real hot
21:22 Tom_itx how did you put that much load on it?
21:22 furrywolf 4/0 copper at 75C is 0.061 ohms/kft, 4/0 alu, also at 75C, is 0.100 ohms/kft... not that much of a difference.
21:23 katsmeow-afk Tom, electric central heat and electric oven and stove and water heater
21:23 furrywolf 0.050 and 0.082 ohms/kft at 20C for copper and alu, respectively.
21:23 katsmeow-afk furry, those numbers are wrong
21:24 furrywolf I copied and pasted from http://www.paigewire.com/awg_conversion.htm
21:24 furrywolf those numbers sound right to me, as I've always read that you only need to use one size thicker of aluminum to get the same resistance.
21:25 furrywolf my limited experience with aluminum is the wire runs ice cold... and the ends melt.
21:26 furrywolf because it never makes good contact, no matter how much deoxit you use and how tight you clamp it.
21:27 katsmeow-afk you haveto massage the deoxit into and tween the wires,, and frankly axle grease works better becaise it won't dry out
21:28 furrywolf or stick to copper, which seems to work no matter what you do. I've seen a splice made by just twisting one wire onto the side of another handling 60A for decades...
21:28 katsmeow-afk hmm, alibaba is selling "16 SWG electrical resistance of aluminum wire Min. Order: 320 ... "
21:38 furrywolf http://tetralite.com/probe/images/DigitProbe01.jpg hrmm, I bet I could build one of those...
21:40 katsmeow-afk The Pope has accepted the resignation of an Argentine bishop after the publication of pictures showing him embracing a woman on a Mexican beach.
21:40 katsmeow-afk Bishop Fernando Bargallo, 57, was photographed in the sea, hugging a woman in a bikini.
21:40 furrywolf yay, more reason to hate religion.
21:41 rrywolf listens to the latest Danzig album... not
21:44 katsmeow-afk furry, Tom did build one
21:45 furrywolf I don't think I have a use for one, though. :)
21:45 furrywolf a tool tip sensor mounted off the side of the table would be much more useful for me.
21:45 furrywolf of course, that could be mostly the same part...
21:49 Tom_itx one what?
21:50 katsmeow-afk mill probe touch finger thingie
21:50 Tom_itx oh
21:50 katsmeow-afk locator
21:50 Tom_itx renishaw probe
21:50 katsmeow-afk ok
21:50 Tom_itx http://tom-itx.dyndns.org:81/~webpage/emc/probe_index.php
21:51 katsmeow-afk furry gave a url to a really complicated one
21:51 Tom_itx somewhere i have renishaw's cad file
21:52 Tom_itx probably not supposed to
21:52 katsmeow-afk it's not like it's too complex to re-engineer from scratch and call it "Tom's Probe"
21:53 Tom_itx you can google the patent
21:53 furrywolf a tool length sensor would be more useful... being able to change tools (I don't have a tool changer or any way to index them other than collars) and not have to re-touch off the part would be very handy.
21:53 katsmeow-afk the turbo "Ford Probe" isn't a bad car
21:53 Tom_itx what do you use for mill software?
21:54 furrywolf I could just make a probe, and have a "tip" that's just a wide flat surface, and a clamp to mount it to the table...
21:54 furrywolf flashcut, because I need a new stepper box before I can use anything else.
21:54 Tom_itx oh that's right
21:54 Tom_itx i have that too
21:54 Tom_itx but it's on the shelf now
21:54 Tom_itx using my new one with linuxcnc
21:55 Tom_itx linuxcnc has a touchoff feature
21:55 furrywolf yeah, that's my plan too, as soon as I build a new stepper box... heh.
21:55 furrywolf flashcut fucking sucks, especially since I'm stuck with a >decade old version.
21:55 Tom_itx so is mine
21:55 Tom_itx 1.41
21:55 Tom_itx but i still used it
21:55 furrywolf don't remember what mine is. in storage, like so much of my stuff.
21:56 furrywolf I got the latest version from that era off their web site.
22:14 furrywolf Tom_itx: what kind of contact resistance / time between cleanings did you get?
22:15 Tom_itx i made them and stuffed them in a box
22:15 Tom_itx :)
22:15 Tom_itx it looked like something i should make
22:15 Tom_itx i sent one to zhanx
22:15 furrywolf ah, so you have no life expectancy data. :)
22:15 yahweh oi
22:16 Tom_itx i heard about some guy that made one using gold ear piercings
22:16 furrywolf I'm finding lots of mentions of piss-poor time between needing to clean the balls and dowels.
22:16 Tom_itx which would be better
22:16 Tom_itx use better electrical property metals
22:16 Tom_itx or plate them
22:18 furrywolf hrmm... might need a pretty thick plating.
22:18 furrywolf I was just thinking of gold-plated connector pins of some kind (rca jacks?), but the plating is pretty thin on them.
22:19 ace4016 what does the thickness do? apart from last longer
22:20 Tom_itx there's minimal current thru them so i dunno
22:21 ace4016 copper is more conductive; gold is just more resistant to corrosion
22:22 Tom_itx well mine is steel ball bearings with steel roll pins
22:22 furrywolf so it will rust in about 30 seconds around here. :)
22:23 ace4016 live on the coast? :P
22:24 furrywolf yes
22:24 furrywolf how about niobium?
22:26 furrywolf http://www.ebay.com/itm/Black-Niobium-Barbell-14ga-5-8-Single-/350485048748?pt=LH_DefaultDomain_0&hash=item519a896dac it's used for jewlery, and you could cut something like that apart for both the balls and dowels...

22:37 furrywolf stop flooding. you're going to end up on the actual ignore list if you keep that up.
22:38 Rue_vancouver I have to wait 2 hours for the ferry to get home
22:38 e_vancouver wonders what's up with to
22:39 Rue_vancouver !doresistors 1
22:39 tobbor Rue_vancouver: What is the value of the color grey?
22:40 Rue_vancouver 8
22:40 tobbor Rue_vancouver: Correct. Your score was: 100%
22:40 furrywolf Rue_vancouver: What is the value of the color reddishorangeondarktanbackground?
22:41 Rue_vancouver I have to kill 2 hours we can do this the easy way or the hard way
22:41 Rue_vancouver How about reddish bown on blue?
22:43 Rue_vancouver I had an icecream, that killed about 4 mins

22:43 Rue_vancouver Hi Tom!
22:44 Rue_vancouver ( it's still a drum joke)
22:44 Tom_itx uh huh
22:45 Tom_itx playin with your new toy ehh?
22:45 Rue_vancouver 2 hour wait for next ferry home
22:45 ace4016 you should chat up strangers around you
22:45 Tom_itx not me
22:45 Tom_itx i'm goin to sleep
22:46 Rue_vancouver Just had the final test. Got back in time to go home
22:46 ace4016 mainly of the female persuasion
22:46 Tom_itx my wiring issue on my steppers wasn't wiring at all
22:46 Rue_vancouver C'mon help me kill over an hour
22:46 Tom_itx i had a stepper that sounded like it was growling when i ran it
22:46 Tom_itx turns out the back shaft was rubbing on my enclosure
22:47 ace4016 did you find a tasmanian devil in it when you opened it?
22:47 Rue_vancouver Not a backwards phase?
22:47 ace4016 ah
22:47 Rue_vancouver Ah
22:47 Tom_itx nope
22:47 Tom_itx it was working fine all along
22:47 Rue_vancouver It's hard to appreciate how small a 4 " screen is till you have to use one
22:48 Rue_vancouver I hear google has a $200 tablet. I'm thinking of a splurge
22:49 furrywolf I wonder if there's some way to make contacts that are both repeatable and self-wiping...
22:49 ace4016 he goes away from his workshop and he starts to get consumerism...
22:49 Rue_vancouver I almost got back to the plastics lab at the tech school to take pics of the vacuum former
22:49 ace4016 we need hazmat! STAT!
22:50 Rue_vancouver Repeatable?
22:50 furrywolf they open at exactly the same position, for a measuring device.
22:50 Rue_vancouver Of axis zeroing?
22:51 furrywolf touch probe
22:51 Rue_vancouver On the Cnc I used a switch in series with a interrupter
22:52 Rue_vancouver Why not just use a spring loaded optic switch
22:53 furrywolf very hard to make accurate to the ten thousandth...
22:53 e_vancouver bumps katsmeow wak
22:53 Rue_vancouver .1 thou!?
22:54 furrywolf that's the accuracy of a cheap one. good ones are better. heh.
22:54 Rue_vancouver Laser inferometer
22:55 Rue_vancouver Why does this keep whoising you
22:56 Rue_vancouver Maybe I should YouTube cute puppies for an hour
22:59 Rue_vancouver Nope they seem to have blocked YouTube
22:59 yahweh_ rue
22:59 Rue_vancouver !
23:00 yahweh_ It\s james
23:00 Rue_vancouver What up!
23:00 Rue_vancouver Duh
23:00 yahweh_ I found maybe a lathe for you.
23:00 Rue_vancouver I'm on an iPhone, forgive me
23:00 Rue_vancouver Oh yea. Do tell
23:00 yahweh_ I have a baby in my right hand, it's all good.
23:01 Rue_vancouver How muches I'm in a splurge mood
23:01 yahweh_ It's $35.
23:01 Rue_vancouver Sold
23:01 yahweh_ however it has no chuck.
23:01 Rue_vancouver Tell me about it
23:01 Rue_vancouver Ok
23:01 Rue_vancouver Is it 8' long
23:01 furrywolf is it a wood lathe or a metal lathe? complete(ish)? broken in lots of expensive ways?
23:02 yahweh_ And no motor but that's not a problem.
23:02 Rue_vancouver Np
23:02 yahweh_ It 3 feet long abouts.
23:02 Rue_vancouver Where do I send the money
23:02 furrywolf no chuck, no motor, no spindle, no bed, no leadscrews, no slide, and no lathe? :)
23:02 yahweh_ It's in lower gibs
23:03 yahweh_ at that trading post.
23:03 e_vancouver beats furrywolf with a rolled up newspa
23:03 Rue_vancouver Quay?
23:03 yahweh_ it's an oldy cast iron beast but it looks unbreakable.
23:04 yahweh_ It's where the grocery store used to be.
23:04 Rue_vancouver Oh at kens
23:05 Rue_vancouver Wonder where that came from
23:05 yahweh_ The expensive touristy thrift store.
23:05 yahweh_ unthrift store i guess.
23:05 Rue_vancouver Do you know if it's a metal lathe?
23:06 furrywolf thrift stores here have moldy baby clothes and dollar store housewars.
23:06 Rue_vancouver Yea if I was looking for a useless net float it's the first place I'd go
23:06 furrywolf housewares
23:06 yahweh_ I'll send you the pictures I took if you give me the number of the phone you're using.
23:09 Rue_vancouver Yes it's me
23:10 Rue_vancouver Where is your phone registered Hawaii ?
23:10 yahweh_ sunshine coast.
23:11 Rue_vancouver Huh
23:11 yahweh_ Transfered my number when I moved here.
23:11 Rue_vancouver That's a wood lathe dude:)
23:11 Rue_vancouver Still 35
23:12 Rue_vancouver .....
23:12 yahweh_ It still spins nice too.
23:12 Rue_vancouver Hmmmm
23:12 yahweh_ It's better then the one you have. ;)
23:12 furrywolf I see wood lathes pretty often... that's about all a broken one ever sells for.
23:12 furrywolf metal lathes are much rarer and always have another digit on the price...
23:13 Rue_vancouver I can cut foam on it
23:13 Rue_vancouver And as you know I have a foam to aluminum converter
23:13 yahweh_ indeed.
23:14 yahweh_ Go look at it tomorrow.
23:14 Rue_vancouver For 0 I could make one
23:14 Rue_vancouver But WOULD I
23:15 yahweh_ You'd take forever though.
23:15 Rue_vancouver I'm getting 24 hours closer to death every day
23:16 home ...
23:16 yahweh_ Running out of time to get the mech done.
23:16 Rue_vancouver It's TRUE
23:16 Tom_itx no
23:16 Rue_vancouver Yea
23:16 yahweh_ need a lathe to finish it.
23:16 Tom_itx you don't know but what it may be extended
23:16 Tom_itx or shortened
23:17 Rue_vancouver Well 35 fits in even a robot budget
23:17 yahweh_ 35 plus chuck though.
23:17 Rue_vancouver Tom the universe is a giant calculator my destruction is inevitable
23:18 Rue_vancouver Welder/ pipe coupler
23:18 yahweh_ okay.
23:19 Rue_vancouver Tom if I jumped off a bridge it wouldn't change when I was gonna die
23:20 Rue_vancouver I'd just know a likely cause of it before it might happen
23:21 Rue_vancouver The engineer says the cup IS full the remaining space is safety margin
23:22 Rue_vancouver Hey did I freak you all out or something?
23:22 yahweh_ yeah philosophy is scary.
23:23 Rue_vancouver Shouldn't be posts able with you lot
23:23 furrywolf just because you're bored and wasting time doesn't mean the rest of us are too.
23:23 yahweh_ Actually, I was playing plants vs. zombies.
23:23 Rue_vancouver What's bad about being a plant?
23:24 Rue_vancouver 50 more mins
23:24 furrywolf and now I'm going to operate the anti-internet device for ~5 minutes.
23:25 yahweh_ plants are good. they fight the zombies for me.
23:25 Rue_vancouver Huh
23:26 yahweh_ it a game.
23:26 yahweh_ http://www.popcap.com/games/plants-vs-zombies/online
23:26 yahweh_ babies bath time now..
23:27 Rue_vancouver Name 4 emotions and comment on their effect on learning
23:27 Rue_vancouver I'm no gamer
23:28 e_vancouver looks at the chairs to try to figure out how to turn them into a robot And then he sees the vending machines.
23:29 Rue_vancouver Think I can get them apart with 8 keys and a quarter?
23:30 furrywolf I think you should keep a multitool on you like all sane nerds.
23:30 Rue_vancouver Where is the parallel port on this iPhone
23:32 furrywolf http://sogknives.com/store/S62.html I like that one best of all the ones I've used. get one. then you'll have tools to take things apart. :P
23:39 Rue_vancouver I can see the boat!
23:40 yahweh_ Here Rue, this is a better multi tool. http://www.sigsauer.com/CatalogProductDetails/sig716-patrol-odg.aspx
23:42 yahweh_ Not only can it take things apart but you can use it to get other people to take things apart AND get them to put things together.
23:42 furrywolf nah. it can only shoot things and club things. you have to add the stab-things attachment for it to be a multitool.
23:43 yahweh_ For a one time fee you get basically infinite free labour.
23:43 Rue_vancouver Looks flimsy as a hammer
23:43 yahweh_ Fair enough, how about a flashlight too.
23:44 furrywolf the SOG I pasted in the one I keep with me all the time. been quite happy with it.
23:44 Rue_vancouver They are starting to unload the ferry
23:44 Rue_vancouver Zhanx
23:44 yahweh_ Oh and Rue, I know you're not super keen on paintball but what if I told you we're going to go play on the ferry next week. Would you be interested?
23:45 Rue_vancouver Haha
23:45 yahweh_ Wanna come?
23:45 Rue_vancouver They would throw you over
23:46 Rue_vancouver No I seriously need to vegitate
23:47 yahweh_ Nonono, not an active ferry, it's the queen of sannich. She got sold in 2008 and now she's parked behind gambier ungaurded and awaiting a court date to decide her fate.
23:47 Rue_vancouver bye!
23:48 yahweh_ So lonely.
23:48 yahweh_ Left me with internet people...
23:48 furrywolf lol
23:49 yahweh_ NONE OF YOU ARE REAL!
23:49 rrywolf is
23:50 yahweh_ I've never met you = not real, not even close.
23:51 Mintoris well its more about getting answers to questions really
23:52 yahweh_ Like, where do hotdogs come from?
23:52 yahweh_ And other things I don't want to know.
23:53 furrywolf hrmm, they now have a wire stripper add-on to the multitool I have... but I'd have to pull the knife, file, or saw to put it in.
23:53 yahweh_ OKay, movie time with family. See you all later.
23:53 furrywolf cyas
23:53 rrywolf curls up next to katsmeow-afk and y
23:55 katsmeow-afk hmm?
23:56 furrywolf hmm? it's late, time for wolfies to curl up next to people and yawn!
23:58 katsmeow-afk my internal clockis all messed up atm
23:58 katsmeow-afk again
23:58 katsmeow-afk as usual
