00:00 delinquentme catching back up for the days reading theBear
00:00 delinquentme ?
00:01 theBear maybe :)
02:09 rue_house :( it looks like I lost an image in my second-lst crash there
02:12 rue_house http://eds.dyndns.org/~ircjunk/images/thnkdiff.gif
02:12 rue_house :) that one
02:19 rue_mohr ok, one machine is back, which is good, cause another one went down
02:19 rue_mohr its kinda back, I have to put the guts in the case and screw the lid on
02:19 rue_mohr but its working...
02:19 rue_mohr for now
02:21 tsmeow-afk wok
02:22 theBear rue_mohr, what kinda 'case' should i make for my chiney-puter ? it ran for years bare on a desk, but that's just tempting fate... i'm thinking it's gotta be something kinda pyramid like, or maybe a dollhouse ?
02:23 theBear need top height of maybe 12-16" above mobo base for enough chimney action
02:23 rue_mohr make one from plexiglass layered with threaded rod
02:23 rue_mohr a stack, each platoe just big enough for what it holds
02:23 theBear how about what kinda i could make without spending money or tracking down the rarest of beasts, free plexiglass
02:23 theBear hmm, that would look kinda cool when you say that last bit tho
02:23 rue_mohr offcuts!?
02:23 katsmeow-afk sch20 pvc drain pipe?
02:23 theBear i don't even work in an industrial area anymore... it's trick
02:24 rue_mohr yes, you could flatten 4" pvc pipe,
02:24 theBear hmm... drainpipe would make an awesome sturdy chimney
02:24 theBear i could flatten it ?
02:24 rue_mohr slit it, heatgun, flatten it
02:24 rue_mohr !assist tutorials/mech
02:24 tobbor Possibly http://eds.dyndns.org/~ircjunk/tutorials/mech
02:24 katsmeow-afk or, tall flower vase, the bottom forms an internal mounting flange
02:24 theBear heh, i could chop up a length of square pvc gutter and make it like a panelled modern building
02:25 rue_mohr http://eds.dyndns.org/~ircjunk/tutorials/mech/p1010110.jpg
02:25 katsmeow-afk paperboard concrete form tubes, apply faux marbeling paint job to it
02:25 theBear hehe, i like that, normally i like info in text form, but that's quicker than any text OR video :)
02:25 rue_mohr :)
02:25 theBear wtf ? pvc is brown there ?
02:26 rue_mohr thats orange
02:26 rue_mohr its for communication pipe
02:26 rue_mohr we throw out tonnes of it
02:26 theBear oh, i not good with colours, i guess that cam loses the bit i need to see that orange pvc (i know the stuff)
02:26 rue_mohr you can use white
02:26 rue_mohr or grey
02:26 theBear hehe, i can't see half the colours on resistors, but my boss still likes me more than the guy who just couldn't remember the code :)
02:26 katsmeow-afk bear, i found a new way to price generators: by the pound
02:27 rue_mohr heh
02:27 theBear katsmeow-afk, ouch, makes the insulated chamber quiet ones expensive
02:27 katsmeow-afk the 400lbs genny i got for $100 today, with the automatic power transfer box : http://designerthinking.com/images/generator-big/IMG_1921m.jpg
02:27 theBear and the hitech lightweight ones cheap :)
02:28 theBear you seen kludges genny ? it's awesome ! some kinda big old industrial aircon looking motor and a truck engine on some big solid frame with SOME areas protected by dented old kinda steel fencing grid :)
02:28 theBear ooh, that's a nice looking one
02:28 katsmeow-afk 14 kw
02:29 katsmeow-afk gotta prove to myself it actually works
02:29 katsmeow-afk there's another one, same price
02:39 theBear anyone know if i can use 'dry spray deoderant' instead of hairspray/furntiure polish to get on new rubber handlebar grips and have them stop being slippery shortly afterwards ?
03:17 rue_house kat
03:17 rue_house cohler?
03:17 rue_house if it cranks and wont start, its the brushes on the armature
03:18 katsmeow-afk i dunno yet, i got the manual for Generac 14kw online tho
03:19 rue_house when the brushes go, it cant detect any voltage generated and kills the ignition
03:19 katsmeow-afk what armature?
03:19 rue_house the last one we saw fail did so around 5000 hours
03:19 rue_house ont eh generator head
03:19 katsmeow-afk it has brushes in it?
03:20 rue_house if its similar to what I'm thinking
03:20 katsmeow-afk my 5kw heads have no brushes, ditto the 2.5 kw head
03:20 rue_house the output is off the field
03:20 rue_house the armautre has the excitation power
03:20 katsmeow-afk and it's not self excited,, interesting
03:20 rue_house well, its a clue if you need
03:21 rue_house how many hours on it?
03:21 rue_house maybe the new one was cohler
03:21 rue_house it looks the same
03:21 katsmeow-afk iirc, the one i grabbed is 5xxx or 5xx.x hrs
03:22 katsmeow-afk kohler
03:22 rue_house yup I bets its the brushes
03:22 rue_house they would think the engines shot cause the coughs but wont catch
03:22 rue_house you have to take a fair bit apart to get to it
03:23 rue_house its set up for natural gas/propane?
03:23 katsmeow-afk NG
03:23 rue_house k
03:23 katsmeow-afk i have no NG
03:23 rue_house more power with propane anyhow
03:23 katsmeow-afk i have small propane bottle ,, 25lbs or so
03:23 rue_house I think they run on either
03:23 rue_house I dont know what youhave to adjust
03:24 rue_house and I dont know if anything smaller than a 100lb will freeze up :)
03:24 katsmeow-afk pretty sure the 25 will freeze up, these things are fuel hogs
03:24 katsmeow-afk i figured $300 a weekend, they have no idle-down
03:25 rue_house hmm
03:25 rue_house I dont know numbers
03:25 rue_house we have a landfull that runs on one
03:26 rue_house + solar
03:26 rue_house I'm sure you should check the brushes
03:26 rue_house if someone didn't know what they were doing they would think the engine was shot
03:26 rue_house the fuel pipe looks rusty on the inside, do you think water got in there?
03:27 katsmeow-afk he said both engines ran, but both gennies burned up anything plugged in for a few hours
03:27 rue_house oooo
03:27 rue_house maybe the regulators are pooched
03:27 katsmeow-afk the rust pipe that says HO# beside it? thats the ehhaust
03:27 katsmeow-afk regulators?
03:28 rue_house they have a regulator that operates the throttle for rpm and the excitation current
03:29 katsmeow-afk yeas, i think an overexcited regulator is thrown off by the cracked pcv tube on the side of the throttlebody
03:30 katsmeow-afk it's getting random amounts of air where it shouldn't be
03:30 theBear i get that after a good curry <grin>
03:30 katsmeow-afk heh
03:31 theBear i'm outta practice... had one from round the corner last week, i thought my tummy was gonna die the next day, it just HURT like curry was burning it :)
03:31 theBear almost a straight year of muscle relaxants and painkillers, yer tummy don't like it
03:36 rue_house ok rue_bed had a hardrive failure, so your all on your own tonight
10:43 GuShH cats... they'll sleep anywhere http://gushh.net/tmp/charliepc.jpg
10:44 rue_house kitty is avoiding the fleas on the floor
10:44 GuShH there are none! that I know of.
10:44 GuShH but I do have to clean and polish that floor
10:44 GuShH although I don't like it at all..
10:45 rue_house if you see kitty avoiding the floor (sometimes at great length) its fleas, but they like high things too
10:46 GuShH just went past and noticed he had found that PC
10:46 GuShH rue_house: they like high and hot things!
10:46 GuShH example and old crt tv
10:46 GuShH or monitor.
10:48 rue_house or tv
10:50 rue_house hmm, the screensaver cant find half its screensavers...
10:50 rue_house wonder whats with that
10:55 GuShH o.o
10:55 GuShH rue_house: save the screensaver!
10:56 GuShH really, who saves them? no redundancy whatsoever. also, wait, why are people still using them?
11:03 rue_house more than anything I need it there to stop the screen from going off
11:47 rue_mohr katsmeow-afk where do I go in mirc to remove the join/part messages?
11:48 ace4016 tools -> options -> irc -> options ->
11:50 ace4016 or something like that
11:51 Tom_itx ok i think i found a useable delta cad model
11:51 Tom_itx just getting it in the right units now..
11:56 e_mohr plays with the teflon tube he
11:57 Tom_itx got for what?
11:58 rue_mohr 3d printer
11:58 rue_mohr I got it in the middle of building the head, I dont knwo if I need it anymore
11:58 Tom_itx http://www.youtube.com/watch?v=Er-hhdF7SYQ&feature=youtu.be%20buzz
11:58 Tom_itx i got the files for that
12:00 rue_mohr hah, I have to find a ver of flash that works on 98
12:03 rue_mohr flash 7 that I have is apparently too old
12:04 rue_mohr oh I have 9
12:04 rue_mohr those are beccoming popular
12:51 katsmeow-afk "Let's get one thing straight. You are behind the counter because you have to work for minimum wage. I'm on this side asking to see the good jewelry because I make considerably more." -- Former Secretary of State Condoleezza Rice, who reportedly said this to a clerk in a jewelry shop.
12:53 katsmeow-afk that statement sorta redefines the word "asking" too
13:03 katsmeow-afk Some researchers speculate that insomnia might trigger your body to release more of the stress hormone cortisol. High levels of cortisol have been linked with high blood pressure and diabetes, which are both risk factors for cardiovascular disease.
13:13 katsmeow-afk A daily dose of 2 grams of Curcuma domestica extract was found to provide pain relief that was equivalent to ibuprofen for the relief of pain associated with osteoarthritis of the knee.[9
13:37 horrror I need a good starter kit
13:37 horrror something a little complex than NXT but not too hard
13:40 tsmeow-afk is STILL wondering why shrdlu didn't take over the w
13:45 katsmeow-afk <BigCityReporter> "farmer reports theft and mutilation of all his kaupes: 'all that's left in the field is kaupe eyes', more news at 10"
13:57 tsmeow-afk thinks the idea of robots in the workplace should be re-evaluated, not to replace people, but if people got 10 minutes per hour with a robot to do anything, instead of "price of living" wage hikes, for meeting workplace goals, work might be more
13:58 tsmeow-afk tells her robot to study c
14:22 tsmeow-afk pokes
14:22 ace4016 :P
14:22 ace4016 you're popping up in ever channel now :D
14:23 katsmeow-afk sorry
14:23 ace4016 don't be
14:23 ace4016 it's enjoyable
14:23 katsmeow-afk i crave knowledge, and sometimes i even seek it
14:58 katsmeow-afk damned channel nazis, no one was talking, i was trying to show train of thought and discussion, and what i get is "can you stop?"
14:59 ace4016 most channels, especially on freenode, are like that; also, most IRCers don't like large pastes and would prefer a direct link or a paste site link
14:59 katsmeow-afk there was no link to that two sentences
15:00 ace4016 paste site then i guess (for other channels...large text dumps seem to be acceptable here in #robotics)
15:01 ace4016 but, to comment on what you pasted, yea; OS/environment changed, but still doesn't really tell anyone why shrdlu "failed"
15:02 ace4016 hm...i should get back to more project planning stuff :/
15:02 katsmeow-afk from what i can tell, it wasn't being upgraded until the OS was changed, at which point it no longer ran properly anyhow
15:03 ace4016 the environment should have been taken into account for the transition, but hindsight is 20/20
15:03 katsmeow-afk it would be like trying to run a flash movie on windows 3
15:04 katsmeow-afk apparently, no one has been able to recreate the environment as it was back then, the computer, the OS, the LISP that SHRDLU was written in, the otehr langauges used to assist (microschemer, planner, etc)
15:05 ace4016 not sure they need to be recreated, just transitioned to
15:05 ace4016 but is it worth it?
15:05 ace4016 (properly transitioned to...not just herp a derp place code here and hope it works)
15:05 katsmeow-afk and the lisp used was patched at the machine code level, and not documented, the source wasn't updated with those patches, so cannot be compiled to a working version
15:06 katsmeow-afk my resulting thoughts is that shrdlu didn't fail while it was in a working environment, the environment changed and no one kept on top of it
15:07 katsmeow-afk but it pisses me off that it DID NOT FAIL, yet now everyone is writing new code to hardwire how to get a beer from the fridge (and failing) or take the trash out (and failing) or etc
15:08 katsmeow-afk and there's applications all over the place for such functionality
15:09 katsmeow-afk i go do things irl now
15:10 ace4016 hrm, can't really say shrdlu didn't "cheat" though if the implimentation was unknown and its performance wasn't measured by objective tests
15:10 tsmeow-afk keeps thinking if such functionality that was 30 yrs ago was commonplace, we'd have sooooooooo much
15:10 katsmeow-afk cheat?
15:11 ace4016 it's possible the way it did things wasn't exactly as elegant as you think; or maybe it is; not sure if there's enough info to validate it
15:11 ace4016 might have to look into it further
15:11 katsmeow-afk isn't high school about cheating, they give info so the students don't need to figure out how each others lungs work on their own
15:12 ace4016 o.0
15:12 katsmeow-afk ok, bbl
15:12 ace4016 alright
16:58 tcial hi
17:06 ace4016 hi
17:06 tobbor Hello ace4016
17:09 tcial Any ideas on making cardboard wheels have more traction
17:09 tcial Do you think rubber bands would work
17:10 ace4016 might work
17:11 tcial http://i.imgur.com/a07e7.jpg
17:11 tcial (sorry for the blurry pic)
17:12 tcial Would it work on those?
17:12 ace4016 i'm in ##electronics too :P
17:12 ace4016 if you can find wide enough and small enough rubberbands, yea
17:12 tcial Ah :D
17:12 tcial Cool :)
17:12 tcial I'll see if they work tomorrow
17:13 tcial And see if I actually own any rubber bands
17:13 chris_99 i wonder if you could use plastercine
17:13 chris_99 around the wheels
17:14 tcial Hmm
17:14 tcial It would get messy on the carpet though
17:16 chris_99 yeah good point
17:16 tcial I guess I can try rubber bands then :)
17:16 tcial I don't see why they wouldn't work
17:17 tcial Just need some casters now
17:17 chris_99 whats your robot do?
17:18 tcial Nothing yet :p
17:18 tcial It's my first robot
17:18 chris_99 alas i haven't made even one ;)
17:18 tcial I tried using an RC car chassis, but it didn't offer enough manoeuvrability
17:19 chris_99 i bet you could make it follow lines not too difficulty
17:20 tcial That's why I have a breadboard at the front
17:20 tcial So I can add stuff
17:20 tcial I'll probably work on making it a photovore first
17:20 tcial And one mate suggested mapping the light levels of a room
17:20 tcial Which sounds cool
17:23 chris_99 then you can attach a vacuum pump to it and clean the floor ;)
17:36 tcial Gotta go, see you around
17:36 tcial Probably tomorrow when I mess something up :D
17:45 Jaggz- "Wow"
22:37 katsmeow-afk During the past two decades, the president of Bihrle Applied Research in Hampton watched premiums rise from $365 to more than $1,600 a month for a family. Although the rate increases have been smaller recently, he now pays $27,000 a month to insure 20 employees <<== and his customers fork out $27,000 a month extra over what the services are actually WORTH
22:37 tsmeow-afk s
22:44 rue_shop3 kat I made a grinder stand I think you would approve of
22:44 ace4016 premiums of what?
22:45 ace4016 insurance?
22:45 ace4016 oh, yea...insurance...
22:47 katsmeow-afk funny, ANY insurance payment is called a "premium",, useto be, a premium was to pay for added riders to a normal policy
22:47 tsmeow-afk can't see rue's new gri
22:48 eBear can, it's glor
22:50 katsmeow-afk heys bear
22:55 katsmeow-afk two pics of a grinder mounting to turn a 1/2 thick hunk of steel bolted to a genny: http://designerthinking.com/generator-big.html
22:55 katsmeow-afk the whole reason for that setup was the plates haveto be true to the genny axle while mounted to the genny
22:57 theBear morning :)
22:57 katsmeow-afk not to the genny frame-housing, but to the shaft
22:57 katsmeow-afk so i bolted the shaft down, and spun the (normally) stationary parts
22:58 katsmeow-afk that rig has been sitting on the table up there ever since my MOM threatened to drive up here and sic dogs on me for using it
23:03 rue_shop3 got the cats, they were out side, a mouse was playing with them
23:03 rue_shop3 hiding under them, trickey
23:04 theBear holy crap ! are you hulk hogan or something ? you destroyed that thread in the last pic !
23:04 katsmeow-afk lol
23:04 katsmeow-afk that is a 1/4 bolt, it's not so big
23:04 theBear hmm, still tho :)
23:04 katsmeow-afk i can do extreme closeups :-)
23:07 katsmeow-afk so i get threatened with being skinned and disembowled by rottwiler attack if i finish and use that thing
23:07 katsmeow-afk i absolutely do not understand humans
23:08 katsmeow-afk but i do know, they don't want me around,, but imagine your mom driving 10 hours each way to tell you she'd be the one leading the attack on you for using a generator
23:08 katsmeow-afk i still shake
23:09 ace4016 ?
23:09 ace4016 why would they not want you to use a generator? i don't get it
23:09 ace4016 is it noisey or something?
23:09 ace4016 what do they lose if you use a generator?
23:10 katsmeow-afk ace, you cannot hear my gennies when on my front porch where they live, and i can hear everyone else's genny while mine is running
23:10 katsmeow-afk cept i have not run mine in 10 yrs now
23:11 katsmeow-afk the carbs are wrecks, and i imagine the engines are frozen
23:11 ace4016 so why do the care and threaten you if you use yours?
23:11 ace4016 they*
23:12 katsmeow-afk i do not know, except: they think mine are as loud as a 747, and they think i am stealing from the powerco if i use them
23:13 katsmeow-afk my cats stood on my genny box with one running in it, and all was fine till the neighbor cranked his up and then they were terrified
23:14 katsmeow-afk i built a sound muffler box, with forced air blower
23:14 katsmeow-afk the blower is inside the box, and the inlet and exhaust are baffled by 2ft square concrete columns
23:15 katsmeow-afk it's lined with carpet, the gennies are on rubber, i haveto open the front door and go out to the box if i want to hear them
23:16 katsmeow-afk i do not understand
23:19 katsmeow-afk how is making electricity the powerco has never seen stealing from them??
23:20 katsmeow-afk if they have no physical connection to my property, how am i stealing electricity from them?
23:20 theBear lol, same way one 'steals' signals that the cable companies broadcast thru ones OWN BACKYARD without ones permission !
23:22 katsmeow-afk bear, i went up and cut the SE drop from the pole pig, that's how disconnected i made it, to shut up the accusations that i was stealing power,, but that didn't satisfy anyone
23:22 katsmeow-afk they'd already decided i was a lowlife thief, and didn't believe a word i said
23:22 katsmeow-afk THAT's what having solar panels and a genny does for you here
23:24 ace4016 those alabamians don't understand that their fancy techonology
23:24 ace4016 s/thier/there/
23:43 katsmeow-afk heh, i accidently won a sma-bnc adaptor
23:43 katsmeow-afk 90 cents
23:46 katsmeow-afk i also forgot to eat breakfast, lunch, and dinner (it's still in the nukebox)
23:48 ace4016 i did that yesterday; made it up by eating eggs and loads of bacon
