09:26 Triffid_Hunter yeah, what an excellent scam
09:26 rue_house universities have a good one going too
09:28 DagoRed So very true rue.
09:28 katsmeow-afk in the 90's, it was easy for banks to charge 2x the sale price on a 30 yr mortgage; you buy for $70k, pay the bank an additional $140k in financing
09:30 rue_house nowonder the economy collapsed, nobody turned out to be abel to actually afford anything
09:30 DagoRed That's the be truth for a while. Also a lot of people went for adjustable rate mortgages which ballooned over time.
09:31 DagoRed Many people didn't know that's how they worked.
10:11 furrywolf meh... I'm running dangerously low on cash. need to find things to sell asap.
10:11 furrywolf I have bills due on the first that I won't have money for unless I find a way to bring some more in.
10:16 rrywolf flops on katsmeow-afk and s
10:46 furrywolf UPS Load : 037.4 % Voltage : 22.74 VDC
10:46 furrywolf grrrr
10:51 furrywolf low on money, low on battery, low on stuff to sell.
10:54 furrywolf I think I've sold pretty much everything I have of value that I don't have an immediate use for.
10:54 rrywolf curls up and s
11:08 furrywolf and low on pettings. :(
11:24 goRed pets furryw
11:24 DagoRed I think you need a bath.
11:56 tsmeow-afk sstttrrreeeeeeeEEEEEEEEEEeeeeeeeeeettttcchhhheess
11:57 DagoRed Hey Kat
11:57 katsmeow-afk hi komodo
11:57 katsmeow-afk err, dago
11:57 katsmeow-afk umm
11:57 katsmeow-afk so how are ye?
11:57 DagoRed Looking at a new job.
11:57 DagoRed Looks likely I'll be moving to Charlotte, NC
11:57 katsmeow-afk what happened to theold one?
11:58 DagoRed No raise and they're treating me like shit.
11:58 tsmeow-afk
11:58 DagoRed So yeah... nearly double the pay and a nice hacker space that would compete with Rue's shop.
11:59 DagoRed I'm very tempted and moving forward.
11:59 DagoRed The question is to bring the girlfriend around or not.
11:59 rrywolf flops on katsmeow-afk's
11:59 katsmeow-afk only she can answer that one
11:59 tsmeow-afk pets the f
11:59 DagoRed Actually it's more of my decision.
11:59 DagoRed I've never met someone I both enjoyed and despised so much.
12:00 katsmeow-afk so if she says "no", you're dragging her along anyhow?
12:00 DagoRed Oh it looks like the answer is yes. The question is do I want a yes or no?
12:00 katsmeow-afk oh
12:00 katsmeow-afk well, tis difficult to find good humans
12:01 DagoRed Agreed. And she bounces between good and dead weight.
12:01 furrywolf is she good with a strapon?
12:01 DagoRed Not that I know of nor do I feel that is an important quality.
12:01 furrywolf bah
12:02 tsmeow-afk must be "bah" too, haveing never even seen a str
12:03 DagoRed katsmeow-afk: you have the internet, only you can solve that problem.
12:03 furrywolf lol
12:03 Tom_itx meh, find a new job... find a new girl
12:03 katsmeow-afk question is: is that a problem?
12:03 Tom_itx unless she's a keeper
12:04 katsmeow-afk anyhow, i meant irl, anyone can get a pic of something online
12:05 DagoRed Tom_itx: She has the potential.
12:05 Tom_itx they all 'appear' to
12:05 DagoRed However.... lack of enthusiasm for me and motorcycles means I might need to kick her to the cub.
12:05 Tom_itx sounds like a done deal
12:05 DagoRed This one never lived on her own, has a graduate degree but was unemployed until recently for a temp job.
12:05 DagoRed *curb
12:06 Tom_itx that description doesn't sound so promising
12:07 katsmeow-afk :-/
12:07 Tom_itx you find one with a bachelors deg working on a doctorate telling you 'honey go play with your toys'.... keep that one
12:08 furrywolf no, you want the one that wants to help with the toys. :P
12:08 DagoRed She wants to go for her doctorate.
12:08 rrywolf had one waaay back when with a bedroom full of harley part
12:08 furrywolf (and other toys, too!)
12:08 Tom_itx oh.. must have the job to go with the degree too
12:09 Tom_itx with no current student loans
12:09 Tom_itx both my in'laws are bitching about that now
12:10 DagoRed Yeah... she has $50k of student loans.
12:10 DagoRed While have less than $3k and my car.
12:10 katsmeow-afk with no current student loans = already has a job, 'cause the loans are paid off
12:13 DagoRed Yeah... she's 27 and has been unemployed for 2 years
12:13 DagoRed since graduating.
12:14 Tom_itx http://www2.electronicproducts.com/Image_of_the_Day_Shuttles_Come_Nose_to_Nose-article-Imbd_17_Aug2012-html.aspx
12:14 katsmeow-afk damn, i must be utterly worthless and really dispised, i 2x as old and been out of work 10x as long
12:15 Tom_itx but you got life long sperience
12:15 katsmeow-afk 15x as long, even
12:15 katsmeow-afk Tom, i wish someone was paying me for it
12:15 Tom_itx http://www2.electronicproducts.com/Bionic_eyeballs_restore_vision-article-FANE_Retinal_prosthetic_Aug2012-html.aspx
12:17 DagoRed her degree is in psychology.
12:17 DagoRed katsmeow-afk: You're worth more than she is. There is no doubt about it.
12:17 Tom_itx oh gawd
12:17 Tom_itx i dated one of those
12:18 katsmeow-afk Volkswagen’s announcement that their 2013 Jetta Hybrid successfully recorded a speed of 185.394mph at the Bonneville Salt Flats near Wendover, Nevada.
12:18 katsmeow-afk don't people take psychology because they have psychological problems?
12:18 katsmeow-afk Volkswagen’s Jetta Hybrid combines a 1.4-liter turbocharged, direct-injection four-cylinder TSI gasoline engine, capable of generating 150 horsepower, with a seven-speed DSG dual-clutch automatic transmission and an electric motor that adds an additional 27 horsepower.
12:18 katsmeow-afk It gets 45 miles per gallon and can from 0 to 60 in 9 seconds flat.
12:18 Tom_itx seems so
12:18 furrywolf yes, they do.
12:19 DagoRed Most are evaluated yes.
12:19 furrywolf subaru's diesel gets 60mpg and makes 154hp... and isn't a stupid hybrid. :P
12:19 DagoRed furrywolf: which model is that?
12:19 furrywolf DagoRed: any of them. they have the same engine.
12:20 DagoRed I wasn't aware they sold any (in the US that is)
12:20 furrywolf note that they're not available in the US, because certain states refuse to allow efficient diesels...
12:20 DagoRed wtf
12:20 katsmeow-afk so why isn't anyone putting 2 such engines in medium trucks, getting 300hp and 30mpg?
12:20 DagoRed I swear I want to make a roadster that runs on a diesel.
12:21 furrywolf california emissions laws measure emissions as a percentage of tailpipe gasses, rather than grams/mile or other units... and when you're burning so little fuel, there's very little emissions, but the percentage is higher.
12:22 furrywolf they'd need to add urea injection to make it pass, which subaru says is an unacceptable cost and hassle for buyers, and would kill sales.
12:22 katsmeow-afk so push the turbo up some to add more air and dilute the percents
12:24 furrywolf there's a limit on o2 percentage in the exhaust, I think it's 8%, but I'd need to check my last smog check to see.
12:24 katsmeow-afk well, i can't fix everything
12:26 furrywolf adding an expensive fluid consumers have to constantly refill is really bad for sales, not to mention that it's only available, at least in many areas, from semi-truck dealers... but they say they can't make it pass california emissions any other way.
12:27 furrywolf so instead they don't sell it in the US, and we don't get 60mpg in a full-size all-wheel-drive station wagon.
12:27 DagoRed wtf
12:29 katsmeow-afk yeas, seems there may be a mandate by EPA to yank all Series 92 Diesels out too, specially from boats
12:29 katsmeow-afk they're 2-cycles
12:31 furrywolf it's especially bad with the modern efficient diesels... they're putting out the same power on HALF the oil, and we won't allow them. we have to have a good reason to keep oil prices high and invade the middle east, you know...
12:33 tsmeow-afk has always been disappointed with the usa's non-policy on energy, and store-bought eng
12:35 furrywolf brb, seeing if I have enough battery left to microwave some food-like items
12:51 DagoRed welcome back
12:51 katsmeow-afk ditto
12:51 katsmeow-afk i didn't mean to cause that
12:52 DagoRed lol
12:52 DagoRed nice
12:53 katsmeow-afk ;-)
12:53 katsmeow-afk i need to go do equally grand events irl
12:53 katsmeow-afk bbl
12:54 DagoRed nice
14:17 rue_house I have to shut down my machine, the bank needs to borrow my UPS
14:18 rue_house ok I'v finished saving code and closing terminals
14:19 DagoRed The bank needs to borrow his UPS?
14:19 DagoRed That's strange.
14:19 DagoRed Oh Canada
14:32 Keknom canada full of many strange bizare creatures that attempt to claim they are people
14:35 Tom_itx i'd charge them darn good for that
14:43 rue_house ok , no ups, hope this is a nice week
14:46 Tom_itx bank panic?
14:46 rue_house yea, this mornin their ups decided to just turn off
14:47 Tom_itx did they think to turn it back on?
14:47 rue_house so 6:00 tonight I'm bypassing it and were installing two temporary ups'
14:47 rue_house they cant have a ups in the system that *just* shuts down
14:48 rue_house randomly
14:48 Tom_itx another long day for rue
14:48 rue_house one of the temps is my ups for this machine
14:48 rue_house 1100VA online truesine
14:48 Tom_itx well which is more important??
14:48 Tom_itx really....
14:48 rue_house heh, I'll be ok for a while
14:49 Tom_itx how's your reprap coming btw?
14:49 rue_house when I finished building all the avr toolset I found out the install path was wrong and the programs were only usable by root
14:50 rue_house the arduino program wont run as root iirc
14:50 rue_house so i have to recompile it all
14:50 rue_house then i can test the tip heater
14:50 Tom_itx what control software are you gonna use?
14:51 rue_house the avr toolset dosn't work on debian testing
14:51 rue_house slic3r and uh
14:51 Tom_itx is that control software or drawing software?
14:51 rue_house it layers the model file
14:52 Tom_itx what do you use to draw the model?
14:52 Tom_itx i want something totally free
14:52 Tom_itx actually i'm not making a reprap yet
14:52 rue_house it looks like the choice is openscad, which is terrible
14:52 Tom_itx the delta intrigues me though
14:54 rue_house its a script based cad program
14:54 rue_house I'm working on writing a proper CSG cad program
14:54 rue_house I'm haivng challanges rotating a 2d circle in 3d
14:54 rue_house :)
14:54 Tom_itx when do you plan to use the reprap?
14:55 rue_house good point, I need to keep my goal hilighted
14:55 Tom_itx do you get much out of #reprap?
14:55 rue_house by friday I want the software recompiled, by end of day sunday I want a working tip heater
14:55 Tom_itx i pissed em off right off when i joined
14:55 rue_house yes, tey are pretty good
14:55 rue_house I have to go
14:55 Tom_itx bye bye
14:55 Tom_itx i fixed my nozzle
14:56 Tom_itx per trif's recomendation
14:57 GuShH arduino? respect--;
14:57 GuShH Tom_itx: what did you say to piss them off?
15:15 Tom_itx who knows
15:16 Tom_itx asked about a couple different ways of doing things and they thought i was invading their little world
15:16 GuShH lol
15:17 Tom_itx have you seen the new delta bot someone is working on?
15:17 Tom_itx it is pretty cool i think
15:17 Tom_itx looks like it may be a bit unstable but hard to tell
15:18 ShH p
15:23 Tom_itx http://reprap.org/wiki/Rostock
15:38 furrywolf grrrr. HATE COUNTY. hate. hate. I sent my airport license proposal to the county over a week ago, and confirmed they'd received it, and would be working on it. I called the woman doing them today to ask how it was going, "oh, I've been really busy, haven't even had a chance to look at it."
15:38 furrywolf grrr, and I hate my internet connection, too.
15:38 furrywolf bbl
15:39 Tom_itx busy doing her nails?
17:57 Guest86179 ..
18:16 katsmeow-afk .,.
18:32 commonpa1sword hi
18:56 commonpa1sword what's a good robotics forum?
18:58 katsmeow-afk depends, "robotics" is a huge area
19:00 katsmeow-afk i need a robot to climb trees, no one else does, but i'd think a forum to do that would be good
19:02 katsmeow-afk rue is making a robot to extrude multicolored plastics in patterns (reprap)
19:02 katsmeow-afk zhanx makes spiders
19:04 katsmeow-afk orlok or ace made a IR vision scanner for a wheeled robot to find toads
19:11 commonpa1sword what's a good general robotics forum
19:12 katsmeow-afk this is the only one i am in
19:12 commonpa1sword I work on a site for controlling robots online and want to find other sites like it and talk about robots on the internet
19:13 katsmeow-afk you mean "physical robots that other people can operate via the internet", or "software bots" ?
19:16 commonpa1sword physicial robots people can control online
19:16 orlok morning
19:17 tsmeow-afk waves at o
19:17 orlok theres letsmakerobots, but thats more little autonomous toys rather than remote control stuff
19:17 lok waves
19:18 orlok have you seen those devices kind of like reusable cable/zip ties?
19:18 orlok for fastening subinet handles together
19:18 katsmeow-afk no
19:19 katsmeow-afk rue prolly has, but he's afk atm
19:20 orlok http://blog.consumerbell.com/wp-content/uploads/2012/03/consumer-recall-news-900000-Child-Proofing-Cabinet-Locks-Recalled.jpg
19:20 orlok heh, how appropriate
19:20 orlok the bub has brokwn two of them
19:20 orlok the cables actually snapped
19:21 katsmeow-afk but she's not even a yr old yet!?
19:21 orlok the ones we have are different, but same basic idea
19:21 orlok ratchet and a strep with teeth like a cable tie, but with a pair of buttons to release
19:21 orlok yeah, i know
19:22 katsmeow-afk you're a genius, what about a internal latch that opens only if the person there has a wireless pendant ?
19:23 orlok heh, they make them, $20 each compared to $10 for 3 of the cable things
19:23 lok starts running into network MTU is
19:23 katsmeow-afk oh, i'd use the puter to locate the pendant, and then open a lock if the pendant is close to it, i wouldn't use a direct-pendant-lock system
19:27 katsmeow-afk that way the pendant also opens the garage door, knows where to send the robot when you call for it, turns on the outdoor lighting as needed at nite, etc
19:28 rue_house I'v seen releasable zapstraps
19:28 Tom_itx i'm watching the system monitor on my atom and one cpu was at 100% then i looked back again and it was down to like 12% and the next one was at 100%
19:28 Tom_itx <Tom_itx> does it load balance based on heat or something?
19:28 Tom_itx <Tom_itx> it keeps swapping cpu cores
19:28 Tom_itx rue_house
19:28 Tom_itx you need to hurry up with your reprap so you can print mine
19:29 Tom_itx rue_house, what do you use with open scad to convert these files to gcode layered to print?
19:29 katsmeow-afk i think the cpu being at 100% means it has no time to stay current on the load balancing, ergo it's out of sync with each other
19:29 Tom_itx they keep swapping out though
19:30 rue_house dunno
19:30 rue_house slicer converts them to layered gcode
19:30 Tom_itx link?
19:31 rue_house http://slic3r.org/
19:31 rue_house its a pain-in-the-ass pile of perl
19:31 Tom_itx holy crap.. it finished rendering
19:32 rue_house your not using openscad on an atom are you?
19:32 Tom_itx yeah
19:32 Guest86179 what's the S for in scad?
19:32 Tom_itx also on my other xp pc
19:32 rue_house script
19:32 Guest86179 ew
19:32 rue_house you dont draw your part, you program it
19:32 katsmeow-afk slow ;-)
19:33 rue_house its a terrible waste of the word cad
19:33 Tom_itx i agree
19:33 Guest86179 indeed
19:33 rue_house its like povray
19:33 Guest86179 I hate povray.
19:33 rue_house but language incompatible
19:33 Tom_itx i won't use it but i wanted these files
19:33 rue_house I'm working on writing a proper csg cad program
19:33 Tom_itx well i'm not gonna wait for you
19:33 rue_house I dont recommend you do
19:34 m_itx releases a few butterf
19:34 rue_house I been 3 days on how to draw a proper 2d circle in 3d
19:34 tsmeow-afk chases
19:34 e_house tries to reach tehm but cant cause he's stuck to su
19:34 Tom_itx i'd like to mill these parts from plastic but i'm unsure what type to use
19:34 rue_house at 6:00 I have to go back to work
19:34 Tom_itx HDPE?
19:34 katsmeow-afk it's getting dark too early
19:34 rue_house what parts?
19:35 Tom_itx rue_house what is that plastic you're getting?
19:35 rue_house the spool is PLA
19:36 katsmeow-afk you won't believe this: remember i said the neighbors dogs hated me using a sprayer for poison ivey years ago? i got a $2 bottle to spray soap water on plant bugs, the dogs are over 200 ft away, they went bananas when i used the spray bottle
19:36 rue_house options are PLA and ABS
19:36 katsmeow-afk today
19:36 Tom_itx http://reprap.org/wiki/Rostock
19:36 rue_house katsmeow-afk, they have been traumatized with one somehow
19:36 Tom_itx i downloaded the files
19:36 Guest86179 you can use those with cats
19:36 katsmeow-afk TWO HUNDRED FEET AWAY
19:36 rue_house hmm good luck on that tom
19:37 rue_house katsmeow-afk, strange
19:37 rue_house I wonder what they did to those dogs
19:37 rue_house damn, no time for a nap
19:38 tsmeow-afk gives rue 400mg of caffine and tucks him into
19:38 e_house bu
19:38 katsmeow-afk it will kick in in 20 min
19:39 katsmeow-afk climb down off the ceiling and go back to work
19:40 katsmeow-afk so there's no way i can make ball nuts for these almost free ball thread rods?
19:41 Guest86179 use rue_house's balls
19:41 katsmeow-afk :-/
19:42 Tom_itx what size is the threaded rod for?
19:43 katsmeow-afk i dunno, i didn't have any measuring devices with me, but the rod is ~1.25 dia , 10ft long, several pieces, nearly free
19:43 katsmeow-afk plus the 2" rod
19:43 Tom_itx get it and talk about it later
19:45 katsmeow-afk thing is, i believe fitting a ball nut to it won't make it accurate, it will be merely very low friction stuff, so is that worth buying it with no intended current use for it?
19:45 katsmeow-afk i am short on money
19:45 Tom_itx well skip it then
19:45 katsmeow-afk i'd hate to see it torched and melted, cause they thought it was rebar
19:46 Tom_itx that's why i hacksawed off the end of a 5/8" plate and cut it down so i could make a hot end for the reprap
19:47 katsmeow-afk umm, o
19:47 Tom_itx or i'd have gone out and got what i needed
19:48 katsmeow-afk make it a "general stock" buy
19:49 Tom_itx with what?
19:49 katsmeow-afk i dunno
19:49 tsmeow-afk looks conf
19:49 katsmeow-afk i looked at afew prices, a ball nut could cost me $200
19:50 Tom_itx yep
19:50 katsmeow-afk i'd find another way to move stuff at that price
19:50 katsmeow-afk unless i can make the nut
19:50 katsmeow-afk [19:28] <katsmeow-afk> so there's no way i can make ball nuts for these almost free ball thread rods?
19:51 Tom_itx the purpose of ballscrews is accuracy and low friction
19:51 Tom_itx i dunno if you can match that with a home made ballnut. i don't think i can
19:51 katsmeow-afk [19:33] <katsmeow-afk> thing is, i believe fitting a ball nut to it won't make it accurate, it will be merely very low friction stuff,
19:51 Tom_itx and i don't know how they're made either
19:52 Tom_itx i'd sure encourage you to try
19:52 katsmeow-afk i should, i don't have enough to do already
19:53 Tom_itx keeps your mind occupied
19:53 orlok crap, my sister just called.. she's been looking after my cat the past few years
19:53 katsmeow-afk i lost that
19:53 katsmeow-afk tell her your mom is still allergic?
19:54 orlok she took grep, the cat to the vet.. looks like we will be getting her put down on saturday :-(
19:54 katsmeow-afk :-((
19:54 ace4016 :(
19:54 orlok she's something like 15 years old now
19:56 katsmeow-afk Tom, i know how i can cast one
19:59 katsmeow-afk least you will be off work to spend the morning with her, orlok
20:23 katsmeow-afk At issue is the tremendously low concentration of uranium in seawater: about three parts per billion, so that just 3.3mg exist in a full tonne of water. As a result, extracting it is an inherently costly process. <<== a "full tonne" is a 10ft cube, not much water
20:26 katsmeow-afk less, even
20:26 katsmeow-afk a cube 3.1335662403819383943617870111225 feet on each side
20:27 katsmeow-afk a scarey huge gigantic "full tonne" is a cubic yard of water
20:27 katsmeow-afk bbl
20:39 Guest86179 hmm my floor jack needs oil
20:40 Guest86179 can I use gearbox oil?
20:40 Tom_itx put some in mine while you're at it
20:41 Guest86179 I need sae 10w
20:41 Guest86179 I noticed because it had some air trapped, and when I removed the fill screw the level was way too low, so now I'm stuck with no jack.
20:54 kanzure hi katsmeow-afk.
20:54 kanzure rue_house: i have money to give you if your proper csg cad program is proper enough
20:54 kanzure rue_house: let me know sometime. kanzure@gmail.com
21:15 Guest86179 kanzure: vaporware.
21:24 katsmeow-afk humans confuse me: tigerdirect is selling WD harddrive model WD3200AAJB
21:25 katsmeow-afk new for $84 , or broken and refurbed for $116
21:34 Tom_itx ok. open scad sucks
21:41 furrywolf rue_house: feel free to ask me any 3d maths questions... I'm rather rusty, but at one point I was reasonably good at them.
21:44 furrywolf http://fw.bushytails.net/foo-44.png writing raytracers was one of my hobbies for a while. :)
