00:05 rue_mohr its because of hwo the humans arms are attached!
00:06 rue_mohr http://stannarts.net/img/drawings/Lribcage.jpg
00:06 rue_mohr yes, see, that shows it clearly
00:06 rue_mohr that exaplins the seperation used in the linking
00:07 rue_mohr the shoulder blades are inconciquintial
00:07 rue_mohr its the collar bones, thats the key
00:08 rue_mohr but I dont understand why the point of origin tends to be the bottom of the ribcage
00:12 katsmeow-afk the shoulder blades solve angular muscle problems with some shoulder angles
00:15 rue_mohr I been looking at the frames they use for motion capture and somethng wasn't making sense
00:15 rue_mohr but I understand what they are up to now
02:16 iR0b0t1 Broskis
08:53 rue_mohr ?
09:07 gongoputch I have torn open every piece of broken computer peripheral I have, and found quite a few steppers, relays and interesting things to play with. I am now eyeing up 2 *working HP scanjet pluses, both parallel port (totally out of support) interfaces, both with doc feeds. It semi galls me to tear apart something that works, ever. I am wondering if I should ebay therm and maybe get some $$$ to buy stuff that I don't have to google for data sheets on,
09:08 gongoputch I am wondering what the #robotics illuminati opinion(s) are
13:33 katsmeow-afk gongoputch , sell on ebay, it's better karma than tearing apart working equipment , then use that money to buy exactly what you need
13:35 katsmeow-afk for $10 , you can buy parts to build two 10 amp switcher half bridges , which you will not find in two working HP scanjet pluses
13:51 katsmeow-afk of course, it depends on what you are trying to build, and the world economy for HP scanjet pluses
13:54 gongoputch well ... then my karma is toast :)
13:58 katsmeow-afk ouch
13:59 katsmeow-afk i know the feeling: i was once presented with half a carload of Tektronix plugins, some working, some run over by a train , i was told if i did not remove the parts i wanted for free, they'd all be run thru a chipper and tossed into a smelter
14:00 katsmeow-afk for free, mind you, Tek 7000 oscope series plugins, some 500 TM series
14:01 ybit katsmeow-afk: i live closer to you now
14:01 katsmeow-afk i managed to talk the guy into accepting equal weight of other metals that were real scrap, to keep working stuff from being melted down
14:01 katsmeow-afk ybit , my condolences!
14:02 katsmeow-afk praps you can poison whoever did that to you?
14:02 katsmeow-afk and why did that happen? you had hackerspace and access to car parts up there!
14:02 ybit because i'm getting paid to work with other linux enthusiasts
14:03 ybit open source e
14:03 katsmeow-afk oh,, then congrats
14:03 ybit e'rything*
14:03 it is looking at building a humanoid at
14:03 gongoputch Well, I broke the one down that sat in my shed for 10+ years, the other (actually a SCSI interface) worked as of 5 years ago. I found moth and spider nests in it.
14:03 gongoputch more like 15 years.
14:03 katsmeow-afk i'd have thought working on programming was the ultimate in not being physically present on site
14:04 ybit katsmeow-afk: also some professor from UAB is giving me a sailboat
14:04 ybit which is nice
14:04 katsmeow-afk damn
14:04 ybit i'm going to source the parts for my puddle duck racer
14:04 ybit and we are getting a hackerspace setup here as well
14:04 katsmeow-afk liveaboard boat? where will you put it?
14:04 ybit the birmingham sailing club
14:05 katsmeow-afk where's here? there's no hackspace in this bloody state cept in Huntsville
14:05 ybit there's about to be 2
14:05 katsmeow-afk there's a sailing club in Bham?! but there's no water in Bham!
14:05 ybit heh
14:06 katsmeow-afk the closest water to Bham is that skinny "river" out west at Birmingport, and the river/lake out at Pell City
14:07 ybit i believe it's located in pell city
14:07 ybit iirc
14:07 katsmeow-afk so where will you put the boat? and btw, afaik, you cannot live aboard in Pell City limits, and maybe in all of St Clair county
14:08 katsmeow-afk so you have not seen the boat yet?
14:08 katsmeow-afk the marine police out here can act like droids, and they carry two guns
14:09 katsmeow-afk i think there is no place on the lake that is free from the sounds of gods barking
14:09 katsmeow-afk but it's pretty scenery
14:10 tsmeow-afk notes ybit is not talking to her in a timely ma
14:11 katsmeow-afk drat, i missed eating lunch, afk to make a sammich, please feel free to let me know what's going on
14:13 ybit yeah, always
14:13 ybit it's irc, it's acceptable apparently
14:14 katsmeow-afk not talking is acceptable on irc??
14:14 katsmeow-afk and here i wanted to have a conversation
14:14 katsmeow-afk i am so stupid
14:14 ybit katsmeow-afk: i'm getting paid to play... so... yeah.. i'm a bit absent from the chat atm :)
14:15 katsmeow-afk oh, you are at work *now*? see, no one told me
14:16 tsmeow-afk operates best with adequate data in
14:18 tsmeow-afk wants to strangle an un-named UAB professor
14:24 katsmeow-afk i have been wanting to pull up anchor here and drop anchor out of sight and smell of land for 10 years, and spent a lot of money towards that goal,, and he just GIVES you a boat
14:24 katsmeow-afk well, you'll be spending a ton of money on gas commuting to Bham from the lake here
14:26 tsmeow-afk sighs and looks at the floor for a long
14:26 m_itx peers thru the drain
14:26 tsmeow-afk waves at
14:32 katsmeow-afk i got a blood blister pulling that wire tight around pins last nite,, or this morning
14:52 katsmeow-afk http://www.bbc.co.uk/news/magazine-18280000
14:55 rizlah That happens because retarded little nerds living in their motherss basement do not have any contact with females outside of the virtual world.
14:56 tsmeow-afk
14:57 rizlah I see it on IRC too. The second someone says "I'm not a guy" you get idiots saying something or putting up wink smileys/etc.
14:58 katsmeow-afk oh, i am aware of that
14:59 katsmeow-afk they may offer the excuse that "they are just men being stupid" , to which i point out "i play a human irl who carries a gun"
15:02 rizlah I don't understand the whole "men being stupid" idea though. Most people online don't ever get the proper teachings about how to act like a man, so they think being vulgar/sexist is a way of showing that they're some sort of "alpha male" or something, hence the "make me a sammich" BS that you find. The majority of men who actually fit the "alpha" or "manly" category very rarely talk about sexual exploits/sexist stuff.
15:03 katsmeow-afk there was a guy shooting onto my property, i called the cops, they witnessed it and drove down to the gunfire, and the idiots told the idiot shooter where i was, he came up here and was a real jerk until he noticed i was carrying, then he got respectful
15:03 Skwint I know quite a few girls in the gaming circles I play in - I sit in voice chat with them quite happily, and some of them are very good, and most of the time most of us don't make stupid comments
15:03 rizlah Sadly in europe you can't carry, which means you get attacked and just hope the police get there in time
15:04 Skwint when we do, it's no more so than the ones we make to the blokes
15:04 Skwint but then, people acting a dick would be kicked out so I suppose it's self governing
15:04 rizlah In the UK you can go to prison for defending yourself. By that I don't mean the "knock them out, then repeatedly hit them" type of defend, but a genuine "hit until you can get away, then gtfo" sort of defend
15:05 Skwint the UK has a major issue there yes :(
15:05 Skwint actually worse for us blokes, since we actually get attacked more often than girls, statistically speaking
15:05 Skwint and are more likely (sexist or not) to be able to defend ourselves when we are
15:05 rizlah Even worse for tall guys, because they get started on by the short guys at the pub with "little man syndrome"
15:06 Skwint I'm 6'6" and used to teach self defence :/
15:06 katsmeow-afk ok, real life sucks, why make the internet suck too?
15:06 rizlah No matter what happens, defence in that scenario is bad for the tall guy. If you attack back you're seen as "hitting the little guy", if you do nothing you get badly beaten
15:06 Skwint well, real life sucks because of some of the people in it
15:06 Skwint guess why the internet sucks?
15:06 rizlah Internet sucks because we let people use it.
15:08 katsmeow-afk good point
15:08 katsmeow-afk meow
15:15 furrywolf just heard back from the guy with the ni-fe batteries... looks like the deal is $400 plus my spare set of dewalt 18v tools, and he'll deliver them here.
15:15 furrywolf the last bit is quite nice, as he's ~200 miles away, and my truck gets 8mpg at $4.59/gallon...
15:16 furrywolf normally I'd try haggling someone down on the price, but if he's going to do >$100 of delivery, that's good enough for me.
15:16 katsmeow-afk you know they are good batteries? i hear the self discharge when old gets to be 50% of charge per month
15:17 furrywolf I know they're bad batteries. they stopped working 12-ish years after he installed them ~1980.
15:18 katsmeow-afk you can rebuild them?
15:18 furrywolf ni-fe generally lasts 10-20 years before the electrolyte wears out.
15:19 furrywolf so rebuilding them consts of 180lbs of potassium hydroxide, 10lbs of lithium hydroxide, and 60 gallons of distilled water.
15:19 furrywolf consists
15:19 katsmeow-afk and Homeland Security will let you get that? i cannot get anhydrus ammonia :-(
15:20 furrywolf KOH is available in 50lb bags easily, for making biodiesel, soap, etc.
15:21 katsmeow-afk kool, now to find out how that helps me to not buy electricity
15:21 furrywolf LiOH is less common, but it's not considered dangerous from a security point of view (not used for drugs or explosives).
15:22 furrywolf I guess you could make lithium carbonate out of it, but they're probably happy if the nutjobs take a bit of that...
15:23 katsmeow-afk the anhydrus soaks into water like mad as a gas, and the liquid it is coming from gets real cold, presto: refridgeration, or maybe even air conditioning , even with no sunshine,, tho using sunshine to boil the ammonia back out of the water hasto be done sometime
15:23 katsmeow-afk it's such a basic simple worthwhile process that was once legal
15:24 furrywolf construct your refrigeration device, then take it to the local refrigeration shop to be filled? or make friends with someone at one?
15:25 katsmeow-afk both ideas fail, sorry
15:26 furrywolf no local refrigeration shop, and/or staffed by idiots?
15:28 katsmeow-afk if it is worthwhile, it's too big to move from the cellar, and when humans here see a wheelchair they believe it's occupant is brain dead,, and as for being a woman, see http://www.bbc.co.uk/news/magazine-18280000
15:29 rizlah http://www.bbc.co.uk/news/world-europe-18324066
15:30 rizlah If you're not really interested in a case this big, maybe you should gtfo instead of compromising the legitimacy of the trial, no?
15:30 rrywolf has an opinion on the intelligence of people who choose to play those game
15:33 katsmeow-afk judges here have been taped sleeping in court, and not been dismissed
15:35 katsmeow-afk i was told in court if i didn't want to get dog-bit on my property, stay inside, that i could not legally protect myself from a viscious dog, even if it was inside my house
15:35 katsmeow-afk consequently, i have spent several nights sleeping in my car in town because a god would not allow me to exit my car in my driveway at my home on my property
15:36 rizlah Surely the dog is a danger to the public if it's set free to run around without supervision?
15:36 katsmeow-afk and it's illegal
15:36 rizlah Shoot it, then tell the police it ran into your bullet.
15:37 rizlah You fell over and the firearm discharged itself.
15:38 katsmeow-afk well, it took 8 years of court, several arrests, $10k of legal fees, and the *big* dogs are gone
15:38 katsmeow-afk and now, instead of non-lethal self defence being seen as harrassment of the dog when it comes over to bite me, it's now preferable to killing the dog
15:39 katsmeow-afk but while i was trying to move to Fla this last winter, someone got rid of almost all the gods out here, it's no longer a gauntlet of gods in the streets, or trying to get thru fences
15:41 rizlah Better than nothing I suppose
15:43 katsmeow-afk <me> keep your dog off my property
15:44 katsmeow-afk <him> no woman is going to tell me what i can do on my own property
15:44 katsmeow-afk <me> wtf?
15:45 rizlah No offence, but from what I've read about where you live it sounds quite redneck
15:46 katsmeow-afk that's an understatement
15:46 katsmeow-afk <me> i own 12 acres i need fenced, can you give me an estimate of time and cost?
15:47 katsmeow-afk <him> let me talk to your husband
15:47 katsmeow-afk <me> not married
15:47 katsmeow-afk <him> get married, have him call me <click>
15:47 rizlah hah
15:56 rizlah back later
15:56 katsmeow-afk me too
16:02 furrywolf and work for me. bbl.
20:18 rue_mohr katsmeow-afk, pretty sexist up there
20:19 haryv Are quad copters the topic of discussion here?
20:19 rue_mohr always
20:19 haryv okay, this one is..wierd ;) http://www.dailymail.co.uk/news/article-2154283/Cats-away-Artist-turns-dead-pet-flying-helicopter-killed-car.html#ixzz1wng5QHVV
20:20 rue_mohr somehow I dont think he intensly cared for his cat
20:21 moriarty anybody up for tetris? http://sh3sacamill3ion.files.wordpress.com/2012/03/picture-36.png
20:22 haryv ohh she is cute
20:24 moriarty om nom nom
20:25 atom1 there you go rue_mohr
20:26 rue_mohr haha
20:26 rue_mohr so are you making a quad copter?
20:27 haryv Actually, I would. there would be some good reasons to have one.
20:27 haryv would be good for SAR
20:28 haryv in non shielded buildings. we had three men die going into a barge hold. no air inside.
20:28 haryv if something like this was avaible, it would have seen him collapsed.
20:28 rue_mohr Shift A Right
20:29 haryv so is the majority of small robotics still done by c?
20:29 rue_mohr C is the last good low level language
20:30 haryv What are other languages that robotic companies are using?
20:30 atom1 rue_mohr,
20:30 atom1 what's a comment line in an .xml file?
20:30 rue_mohr <!
20:30 rue_mohr isn't it?
20:31 atom1 <!--
20:31 atom1 ok
20:31 rue_mohr a girl on the internet just replied to a message I sent, THIS IS SO COOL
20:31 atom1 stranger?
20:32 rue_mohr yes
20:32 atom1 and you know it's a girl?
20:32 rue_mohr I'm going by what the page says
20:32 atom1 a social site?
20:33 moriarty no an anti-social one
20:34 atom1 ok rue_mohr , what's a crlf in .xml?
20:35 haryv Is there any simulator that takes code and simulates the robot movments on the screen?
20:37 rue_mohr <br>
20:37 rue_mohr ?
20:38 Tom_itx no
20:39 Tom_itx i tried that
21:19 Tom_itx orlok, when does venus pass by the sun?
21:19 Tom_itx is that coming up soon?
22:08 e_mohr goes to comment that its just orbiting, but re-evaluates after applying some con
22:09 Tom_itx i should rather say passing between earth and the sun
22:09 rue_mohr http://inhabitat.com/beautiful-boxes-made-from-repurposed-vintage-circuit-boards/zoroaster/
22:09 rue_mohr kat...
22:10 rue_mohr any36952454, do you think those were custom done for those projects or that they are really recycled
22:12 Tom_itx kinda suspicious
22:13 rue_mohr they would atleast be production overrun, as there is a lot of board repeats
22:14 rue_mohr ah its said the baords are from the 60's that explains a lot
22:14 rue_mohr the rotary switches and the analog boards
22:18 rue_mohr k I can validate one board, its a set of sockets hooked up to a chip like a 74244
22:19 Tom_itx added a 'soft button' to the control pannel tonight
22:19 Tom_itx kinda cool
22:20 Tom_itx rue_mohr, did you see kat's wiring?
22:21 rue_mohr a little
22:21 Tom_itx a html on it now?
23:08 furrywolf Today's Rain: 1.65 in
23:08 furrywolf Storm Total: 2.00 in
23:10 katsmeow-afk that's a good rain
23:10 furrywolf yep
23:10 rrywolf hops on kat's lap, all fl
23:10 katsmeow-afk we had a good one here too, put maybe 1.5" into the pool/tank
23:11 tsmeow-afk looks at all the f
23:11 furrywolf it's still raining
23:12 katsmeow-afk i found 2" check valves for $12 irl
23:13 furrywolf sounds reasonable. pool supply place?
23:14 katsmeow-afk home depot
23:14 home ?
23:14 katsmeow-afk i get so irritated that some stuff is called 2" even tho when it's wide open the unobstructed flow is 3/4
23:15 furrywolf you see big check valves, with full flow, for pool stuff.
23:16 katsmeow-afk ok, i plan on it going on the 2" intake in the pool/tank, first to feed the pump directly, later to gravity feed the cellar tank
23:16 katsmeow-afk so with the gravity flow, i didn't want any restriction
23:17 katsmeow-afk besides, it was about the same cost as a 3/4 brass check valve
23:17 furrywolf be warned the sealing quality can be iffy on cheap check valves.
23:18 furrywolf if they're used for something where a drip would be a bad thing, use a manual ball valve after it.
23:19 katsmeow-afk no, it's just so if the intake pipe (up over the pool side and then down underground) gets air blocked, loosing siphon, i can open the top part of the siphon loop and pour in some water and make it all better
23:20 katsmeow-afk i will put a ball valve where the 2" comes out of the concrete cellar wall, if that line busted somewhere, i'd have 2000 gallons of water in the cellar real pronto
23:21 katsmeow-afk there's 3" drains at a couple places, but it's still a lot of water
