| ybit | http://en.wikipedia.org/wiki/SpaceX_Dragon | 00:16 |
|---|---|---|
| fenn | kind of amazing isn't it.. SpaceX will be taking over from the shuttle | 00:20 |
| fenn | ... proving once again, computer geeks can do anything! :) | 00:21 |
| fenn | or maybe it's just proving how bad governments are at doing anything at all | 00:22 |
| katsmeow-afk | In June 2009, SpaceX CEO Elon Musk stated that the company plans to conduct the maiden flight in 2009 <<== did they? | 00:31 |
| katsmeow-afk | hmm, the Falcon 9 reminds me of the missile in "First Encounter" | 00:32 |
| fenn | yes, the first flight had a boo boo which was fixed for #2 | 00:36 |
| fenn | i recall watching that live, quite a sphincter clencher | 00:36 |
| fenn | the spent stage 1 fairing klonked the stage 2 motor upon separation (unexpected wind shear or somesuch) which caused it to wobble, then the contro system overcorrected and went into positive feedback | 00:38 |
| katsmeow-afk | yeowch | 00:38 |
| katsmeow-afk | how did they fix that? | 00:38 |
| fenn | dont remember | 00:39 |
| katsmeow-afk | Wind Shear [ON/OFF] (off) | 00:39 |
| fenn | heh | 00:39 |
| fenn | oh wait nm | 00:39 |
| fenn | that was 2008 | 00:40 |
| fenn | now i'm confuzzled | 00:41 |
| katsmeow-afk | oh i seem to remember something, they blew the side panels which separated the stages, and the top stage slowed down while the spent stage below it didn't | 00:42 |
| fenn | ok falcon_1 != falcon_9 | 00:43 |
| fenn | falcon_9 has 9x the same engine in falcon_1 | 00:43 |
| fenn | but they are both orbital vehicles | 00:43 |
| katsmeow-afk | my solution was to install a couple JATO bottles to blow the two stages apart while the top stage engines lit | 00:43 |
| fenn | they use a pneumatic cylinder | 00:43 |
| katsmeow-afk | seriously? | 00:43 |
| genehacker | sounds reusable | 00:44 |
| genehacker | is it? | 00:44 |
| fenn | yes | 00:44 |
| katsmeow-afk | but if the same condition exists, that the top stage engine isn't lit while the lower stage overruns it, the pneumatic piston is in one place, while the stages are free to move in 3D | 00:45 |
| genehacker | sweet | 00:45 |
| fenn | what condition? | 00:45 |
| fenn | separation while stage 1 is still running? | 00:45 |
| katsmeow-afk | before stage2 lites | 00:45 |
| fenn | you want to separate before lighting stage 2 | 00:46 |
| fenn | otherwise *BOOM* | 00:46 |
| katsmeow-afk | i agree, but i don't think a point contact pneumatic piston will do it | 00:46 |
| katsmeow-afk | the stage 1 can skew to one side and still overrun the stage2 | 00:46 |
| genehacker | one thing you can do with a pneumatic cylinder that's cool | 00:46 |
| genehacker | is you can hook it up a fluidic or pneumatic control system that doesn't have any failure prone chips | 00:47 |
| genehacker | maybe fluidic ICs but no semiconductor chips | 00:47 |
| fenn | that sounds totally unnecessary | 00:47 |
| fenn | heavy and unreliable | 00:48 |
| katsmeow-afk | i think i'd have a couple or 4 *small* selfcontained engines, like JATO, fire them at separation, guarantee some distance | 00:48 |
| katsmeow-afk | slow down stage1 | 00:48 |
| katsmeow-afk | let stage2 coast up, tho it will still slow while in the air | 00:49 |
| genehacker | jato introduces problems | 00:49 |
| genehacker | do you know why? | 00:49 |
| fenn | what keeps them from blasting hot exhaust onto the bottom of stage 2? | 00:49 |
| fenn | genehacker: they explode randomly? | 00:49 |
| katsmeow-afk | Fenn, angles | 00:49 |
| genehacker | no they can though | 00:49 |
| fenn | katsmeow-afk: you need some distance for that to work | 00:49 |
| katsmeow-afk | all rockets *can* explode randomly | 00:49 |
| genehacker | do you know what human rated means? | 00:49 |
| fenn | not really | 00:50 |
| genehacker | http://en.wikipedia.org/wiki/Human-rating_certification | 00:50 |
| katsmeow-afk | means no bats are allowed to nest uop in the solid boosters prior to deton,, i mean, ignition | 00:50 |
| fenn | isn't that "bat rated"? | 00:50 |
| genehacker | it means really really really comprehensive testing | 00:50 |
| genehacker | but the thing is a human would have to put the jato in | 00:51 |
| fenn | "no humans allowed to nest on top of the spacecraft" | 00:51 |
| genehacker | that might be dangerous | 00:51 |
| fenn | oh pff' | 00:51 |
| katsmeow-afk | what do you mean "a human would have to put the jato in" ,, isn't the rocket built by humans anyhow? | 00:51 |
| fenn | if a technician dies they don't hold a national memorial | 00:51 |
| genehacker | better to fill the rocket up with fuel from far away | 00:51 |
| genehacker | yeah it is | 00:51 |
| * fenn never understood that double standard | 00:51 | |
| genehacker | here's the thing fenn | 00:51 |
| katsmeow-afk | jato is standard equipment in short runway cargo planes | 00:52 |
| genehacker | when you take rockets apart and put them together you have to have 3 technicians | 00:52 |
| genehacker | to do one job | 00:52 |
| fenn | no i don't | 00:52 |
| genehacker | one does the job | 00:52 |
| katsmeow-afk | not they *use* them in a often standard way, but they have them, there's mounting brackets etc on the aircraft | 00:52 |
| genehacker | the other watches the technician doing the job to make sure they're doing it right | 00:52 |
| genehacker | the third documents EVERYTHING | 00:53 |
| fenn | that sounds triply stupid | 00:53 |
| genehacker | or at least that's how NASA does it | 00:53 |
| fenn | it should be a robot doing it in the first place | 00:53 |
| katsmeow-afk | Gemini and Murcury had some stupid problems in the conenctions in interstage couplings, that's why they use 3 techs now | 00:53 |
| genehacker | then that robot should be very very very very very failure proof and have pentuply redundant sensing systems and perfect code | 00:54 |
| genehacker | that's why the shuttle uses old hardware | 00:54 |
| fenn | no, you have a human check what the robot does | 00:54 |
| genehacker | how do you know that human isn't slacking off? | 00:54 |
| katsmeow-afk | magnetic ring memory landed the astronouts on the moon even | 00:55 |
| fenn | you hang him by the balls if the rocket explodes | 00:55 |
| genehacker | how do you it was him? | 00:55 |
| fenn | it doesn't matter if it was him | 00:55 |
| katsmeow-afk | what if she doesn't have balls? | 00:55 |
| genehacker | that's what the other two techs do | 00:55 |
| genehacker | they make sure they do the job | 00:55 |
| * fenn considers various possibilities | 00:55 | |
| genehacker | don't you know anything about NASA? | 00:56 |
| fenn | i guess you'd have to make her hang by someone else's balls | 00:56 |
| fenn | proving once again women are twice as inefficient as men :P | 00:57 |
| katsmeow-afk | no, the rule to hang her by balls is inefficient | 00:57 |
| genehacker | the thing is rockets tend to carry critical cargo | 00:57 |
| fenn | ok but someone has to take responsibility! | 00:57 |
| genehacker | it's much cheaper to do a bunch of inspection than have something not reach orbit | 00:58 |
| fenn | genehacker: but what would motivate the techs to make sure they're doing the job right? | 00:58 |
| genehacker | the other techs, the documentation, the ability to make money if they get the other techs in trouble | 01:00 |
| genehacker | I don't know exactly how nasa does it | 01:00 |
| genehacker | all I know is they're absolutely crazy about safety | 01:00 |
| fenn | whole lot of good it's done | 01:01 |
| genehacker | got us to the moon | 01:01 |
| fenn | "our spaceships are 94% reliable!" | 01:01 |
| katsmeow-afk | got us to the moon and cooked lotsa astronauts to! | 01:01 |
| genehacker | such is the case with complex technology | 01:02 |
| * katsmeow-afk points out the explosion on the way tot he moon, the Cahallenger, and the 100% O2 fire | 01:02 | |
| genehacker | there will always be unanticipatable mistakes | 01:02 |
| fenn | i love how people try to not count the exploded shuttles in reliability figures | 01:02 |
| katsmeow-afk | they were NOT unanticipated, they were stupid | 01:02 |
| genehacker | so were some nuclear bomb accidents | 01:03 |
| katsmeow-afk | sure, but no trained humans volunteered to sit on the nukes while they were set off | 01:03 |
| fenn | nuclear bomb accidents? | 01:03 |
| genehacker | yeah nuclear bomb accidents | 01:04 |
| fenn | example plz | 01:04 |
| fenn | with > 1000 nuclear tests i'm sure there were some accidents | 01:04 |
| fenn | but i've never heard about it | 01:04 |
| genehacker | http://en.wikipedia.org/wiki/1966_Palomares_B-52_crash | 01:04 |
| genehacker | there was a thing on the history channel about it | 01:04 |
| katsmeow-afk | i've not heard of a nuke that went off that wasn't intended | 01:04 |
| fenn | also lots of people got hurt but it was through idiot generals calling the shots even though the scientists knew better.. is that an accident? | 01:05 |
| katsmeow-afk | there's been planes carrying them, drop them, crash with them | 01:05 |
| katsmeow-afk | and i heard a booster detonated in a silo with nukes on it, they didn't go off | 01:05 |
| fenn | nukes only go off if you want them to | 01:05 |
| fenn | very hard to get it to work at all | 01:05 |
| -!- davidnunez [n=davidnun@209-6-203-217.c3-0.smr-ubr1.sbo-smr.ma.cable.rcn.com] has quit [No route to host] | 01:06 | |
| genehacker | well when nukes fail they don't make a big nuclear explosion, the conventional explosives detonate making an effect similar to a dirty bomb | 01:06 |
| katsmeow-afk | and i heard of a ladder being in an access hatch on a missile boat when the crane was given the go-ahead to lift eh missile ot of the tube | 01:06 |
| genehacker | dropping the nukes has resulted in the conventional exploding | 01:06 |
| katsmeow-afk | wrecked the ladder,, and the missile | 01:06 |
| katsmeow-afk | and the silo | 01:06 |
| katsmeow-afk | and a few carreers | 01:06 |
| katsmeow-afk | been a few nuke subs sink while tied up to dock due to stupidity too | 01:07 |
| katsmeow-afk | and several deep-sixed due to the reactor scramming and leaving the boat unpowered in a dive | 01:08 |
| genehacker | yeah | 01:08 |
| katsmeow-afk | one still in the Pacific, two still in the Atl that i know of | 01:08 |
| fenn | u-235 isn't all that radioactive | 01:08 |
| genehacker | some even had nuclear bomb torpedoes | 01:08 |
| fenn | pu-239 is more radioactive but is it really that bad? | 01:09 |
| fenn | you can hold it in your hand and not die | 01:09 |
| genehacker | but not to worry, Pu-210 is insoluble in ocean water | 01:09 |
| fenn | http://www.srs.gov/general/news/photos/button.jpg | 01:09 |
| katsmeow-afk | i heard it said that one atom of Pu0239 inhaled *will* cause you cancer, but it's unlikely you will find an atom of the stuff | 01:09 |
| fenn | not true | 01:10 |
| katsmeow-afk | i didn't say in your hand | 01:10 |
| katsmeow-afk | i said inside you where it will stay a while | 01:10 |
| genehacker | holy cow | 01:10 |
| genehacker | it's green | 01:10 |
| genehacker | IT'S REALLY GREEN | 01:10 |
| fenn | i know someone who inhaled a grain of plutonium.. not sure what isotope or even if it was a single isotope | 01:10 |
| katsmeow-afk | KRYPONITE! | 01:10 |
| fenn | genehacker: it's not green, it's dull silver | 01:10 |
| katsmeow-afk | and krypton is a gas | 01:11 |
| genehacker | well if it's just a grain, then they fish it out of you using a geiger counter | 01:11 |
| genehacker | looks sorta green | 01:11 |
| fenn | apparently it wasn't possible to fish it out | 01:11 |
| katsmeow-afk | praps he coughed it upin slime | 01:11 |
| fenn | he had it stuck in his lungs for 10 years, was in the process of suing los alamos | 01:11 |
| genehacker | plutonium microstructures are cool | 01:12 |
| fenn | anyway i don't think a nuclear bomb hitting the ground is all that big of a deal | 01:13 |
| fenn | i mean you have to clean it up, but it's not a dirty bomb disaster | 01:13 |
| fenn | an active reactor releasing into the environment is a lot worse | 01:13 |
| * katsmeow-afk is going to keep looking up anyhow,, err,, that was a slogan in the cold war | 01:13 | |
| genehacker | you have to clean it up, it's more of a political night mare | 01:13 |
| fenn | medical equipment is probably more reactive | 01:14 |
| fenn | s/reactive/radioactive/ | 01:14 |
| genehacker | medical equipment also has to be human rated | 01:14 |
| katsmeow-afk | i wonder if we can still buy americium in the hardware stores | 01:14 |
| fenn | yep | 01:14 |
| genehacker | yes | 01:14 |
| katsmeow-afk | heh | 01:14 |
| genehacker | you can use it to make a nuclear rocket if you have enough | 01:15 |
| fenn | you can still buy tritium keychains | 01:15 |
| fenn | you can make .. a keychain | 01:15 |
| katsmeow-afk | i considered that briefly | 01:15 |
| genehacker | I still want one | 01:15 |
| katsmeow-afk | any safer than thorium? | 01:16 |
| fenn | safe? | 01:16 |
| fenn | alpha particles don't go through glass | 01:16 |
| katsmeow-afk | they don't use thorium in vac tube emitters or in watch dials anymore | 01:16 |
| fenn | you would have to crack it open and purposefully inhale it (hydrogen is lighter than air) | 01:16 |
| katsmeow-afk | not that i have a clue what all this nuke mumbo jumbo you guys are discussing <whistle><whistle> | 01:17 |
| * fenn waves to CIA-32 | 01:18 | |
| katsmeow-afk | heh | 01:18 |
| fenn | i thought it was radium on the watch dials | 01:19 |
| -!- cia [n=someone@75-120-38-228.dyn.centurytel.net] has joined #hplusroadmap | 01:19 | |
| cia | yep, we heard you | 01:19 |
| fenn | hello someone | 01:19 |
| -!- cia [n=someone@75-120-38-228.dyn.centurytel.net] has quit [Client Quit] | 01:19 | |
| katsmeow-afk | :-P | 01:19 |
| fenn | gee i wonder who that could have been | 01:19 |
| katsmeow-afk | <whistle><whistle> | 01:19 |
| genehacker | hey guys want to harvest plutonium from a sunken nuclear submarine? | 01:20 |
| katsmeow-afk | i freaked out some noob doing that one day | 01:20 |
| genehacker | it's like weapons grade | 01:20 |
| katsmeow-afk | *want* to? not really | 01:20 |
| fenn | what would you do with it? | 01:20 |
| fenn | besides die of radiation sickness | 01:20 |
| katsmeow-afk | i wold not mind having the reactor and engines/generators in working order tho | 01:20 |
| genehacker | make a nuclear rocket, what do you think I'd do with it? | 01:20 |
| fenn | but nuclear rockets made from plutonium kinda suck | 01:21 |
| genehacker | why? | 01:21 |
| fenn | not gas phase | 01:21 |
| fenn | low exhaust velocity | 01:21 |
| genehacker | hmm... | 01:21 |
| fenn | it's something like 2x the performance of LOX/H2 but you get to lug around a nuclear reactor and heat exchangers too | 01:21 |
| katsmeow-afk | the pulse bomb roctet worked on paper, and in models using firecrackers | 01:21 |
| katsmeow-afk | easy way to put 2000tons to Mars in one stage | 01:22 |
| fenn | orion was based on an assumption that never panned out.. the ability to make cheap hydrogen bombs without having to use a fissile starter | 01:22 |
| genehacker | oh dang | 01:22 |
| genehacker | don't need plutonium | 01:22 |
| fenn | also it never would have gotten off the ground politically | 01:22 |
| genehacker | screw the nuclear sub | 01:22 |
| genehacker | heheheheh | 01:22 |
| katsmeow-afk | i thought they *hadto* use fissile to get propulsion outside the atmosphere, from the ablative disk | 01:23 |
| fenn | just say you're a poor developing nation in need of small nuclear reactors | 01:23 |
| genehacker | anyway this one proposed nuclear rocket had so much power it would be VTOL | 01:23 |
| genehacker | and could land on any suitably flat surface | 01:23 |
| genehacker | like a walmart parking lot | 01:23 |
| katsmeow-afk | and remain radioactive for 50k years? | 01:23 |
| fenn | eh? don't all rockets do that? | 01:23 |
| genehacker | a VTOL rocket | 01:24 |
| genehacker | VTOL from fucking orbit | 01:24 |
| katsmeow-afk | been done, genehacker | 01:24 |
| katsmeow-afk | oh,, from orbit? | 01:24 |
| genehacker | has it been done? | 01:25 |
| genehacker | VTOL rockets that go to orbit and back? | 01:25 |
| katsmeow-afk | not from orbit, unless you count the mon landings | 01:25 |
| fenn | huh.. quite a lot of info here http://www.projectrho.com/rocket/rocket3c2.html | 01:26 |
| fenn | "The trouble is the uranium shoots out the exhaust as well." | 01:26 |
| katsmeow-afk | i hate it when that happens | 01:27 |
| fenn | hmm | 01:27 |
| fenn | "In some designs the reaction chamber is spun like a centrifuge. This encourages the heavier uranium to stay in the chamber instead of leaking into the exhaust. This makes for a rather spectacular failure mode if the centrifuge's bearings seize. " | 01:27 |
| katsmeow-afk | oh shit yea | 01:28 |
| genehacker | forgot about projecthro | 01:28 |
| fenn | anyway i wasn't terribly impressed with nuclear thermal solid | 01:28 |
| fenn | the lightbulb concept has a lot going for it though | 01:29 |
| genehacker | http://nextbigfuture.com/2009/06/nuclear-dc-x-recent-nuclear-thermal.html | 01:30 |
| genehacker | here it is | 01:30 |
| genehacker | VTOL SSTO | 01:30 |
| fenn | the sad thing is we don't even need heavy lift rockets, if someone would just put up a rotating tether | 01:30 |
| genehacker | no nanotubes? | 01:30 |
| fenn | just polyethylene | 01:30 |
| fenn | fishing line stuff | 01:31 |
| katsmeow-afk | what if the rocket was large enough to use magnetic containment for the fusion/fission components, while the propellant leakes out of the magnetics? | 01:31 |
| genehacker | someone proposed that | 01:31 |
| katsmeow-afk | yeas, i just did | 01:31 |
| genehacker | how much polyetheylene? | 01:31 |
| genehacker | how long how thick? | 01:31 |
| fenn | 100km long, uh.. i forget how thick | 01:31 |
| fenn | it's tapered | 01:31 |
| genehacker | link? | 01:32 |
| fenn | something like 1 ft wide by 20 micron thick ribbon | 01:32 |
| genehacker | wait | 01:33 |
| genehacker | 20 microns thick? | 01:33 |
| genehacker | as thin as a garbage bag? | 01:33 |
| fenn | hang on.. it's one of these papers | 01:33 |
| genehacker | doesn't that go into the atmosphere | 01:33 |
| fenn | only the very low end, which is made of a different material | 01:34 |
| genehacker | like? | 01:34 |
| fenn | something heat resistant.. titanium i think | 01:34 |
| fenn | blah all these links are wrong | 01:35 |
| fenn | so apparently they took down some papers because of ITAR | 01:36 |
| genehacker | what's that? | 01:36 |
| fenn | bullshit | 01:36 |
| genehacker | dang if I could only find my solar balloon calculations | 01:37 |
| genehacker | I have how much area a garbage bag produces | 01:37 |
| fenn | so apparently hypersonic planes are sensitive information now | 01:39 |
| fenn | sigh | 01:39 |
| fenn | ok '3 braids of 3000 denier Zylon fiber' | 01:40 |
| katsmeow-afk | i wonder if that means they actually made one work | 01:40 |
| fenn | hah no way | 01:40 |
| fenn | we would be able to see it | 01:40 |
| katsmeow-afk | the military wanted them really badly, for cruise missiles | 01:40 |
| fenn | huh? | 01:41 |
| fenn | cruise missiles from space? | 01:41 |
| katsmeow-afk | launch and hit anywhere on earth in 2 hrs | 01:41 |
| fenn | er.. i dont see how that has anything to do with tethers | 01:41 |
| katsmeow-afk | remember the Clinton cruise launch that took hours to reach some site, and everyone left while the missiles were in transit? | 01:41 |
| genehacker | no way | 01:42 |
| genehacker | I don't believe it | 01:42 |
| katsmeow-afk | oh,, i thought you were replying to what i said | 01:42 |
| genehacker | I can't believe it fenn | 01:42 |
| fenn | well genehacker i guess this is the least sucky paper still online http://www.tethers.com/papers/MXERJPC2003Paper.pdf | 01:42 |
| genehacker | 100 kilometers by 1 foot of polyethylene | 01:42 |
| genehacker | is 9 373.82827 garbage bags | 01:42 |
| genehacker | at 20 garbages bags per container at ~$2 | 01:43 |
| genehacker | is 937.382827 | 01:43 |
| fenn | weird how the numbers work out | 01:43 |
| genehacker | $ | 01:43 |
| fenn | tether mass is 9370 kg | 01:43 |
| genehacker | this can't be right | 01:43 |
| genehacker | surely it'd be cheaper | 01:44 |
| fenn | but that number comes from 8870 kg zylon = 500 kg copper | 01:44 |
| fenn | s/=/+/ | 01:44 |
| genehacker | if you could find a factory willing to produce an 100 kilometer long strip of garbage bag plastic | 01:45 |
| fenn | no, it's not the same stuff | 01:45 |
| fenn | not all polyethylene is created equal | 01:45 |
| genehacker | is this electrospun polyethylene | 01:46 |
| fenn | http://en.wikipedia.org/wiki/Dyneema | 01:46 |
| fenn | welp there goes the ol' browser | 01:46 |
| genehacker | still launch cost $500 per kg | 01:48 |
| fenn | saul griffith at it again? "The world kite altitude record for a single kite is being attempted in Australia using (11 km and 10 km long) lines of this material" | 01:48 |
| genehacker | hehehe | 01:49 |
| fenn | $5M is peanuts for international space infrastructure | 01:49 |
| fenn | it cost $40M to renovate my high school | 01:49 |
| genehacker | only $5M? | 01:50 |
| genehacker | did it really cost $40M | 01:51 |
| fenn | well launch cost isn't actually $500/kg is it? | 01:51 |
| genehacker | well more importantly does it work? | 01:51 |
| fenn | "nobody knows" | 01:51 |
| genehacker | what about radiation? | 01:51 |
| fenn | the experiments seemed to work as expected | 01:51 |
| genehacker | tether degradation in space? | 01:51 |
| fenn | not that much radiation in low earth orbit | 01:52 |
| fenn | anyway i don't think it's a problem | 01:52 |
| fenn | the big issue is foreign object damage | 01:52 |
| genehacker | yeah | 01:52 |
| genehacker | and deployment | 01:52 |
| fenn | and simulation, oddly enough | 01:52 |
| genehacker | we can't even get a damn sail to deploy | 01:52 |
| fenn | the tether is long enough that you can't model it as a point mass | 01:52 |
| fenn | also you have to take into account the differing values of gravity along its length | 01:53 |
| genehacker | so cost of this thing is about 5 mil right? | 01:54 |
| fenn | no, more like $50M i guess | 01:54 |
| fenn | and then it can bootstrap itself | 01:54 |
| genehacker | still less than the budget of some small cities | 01:55 |
| fenn | i'm not good at estimating costs | 01:55 |
| genehacker | http://www.cnn.com/2008/SHOWBIZ/03/17/mccartney.mills/index.html | 01:56 |
| genehacker | hmmm... get celebrity | 01:56 |
| genehacker | interested in this, get celebrity to get divorced with other celebrity,??? profit! | 01:56 |
| genehacker | http://www.bloomberg.com/apps/news?pid=20601109&sid=an7Pm3hkmauw | 01:57 |
| genehacker | scam the mormons get to space! | 01:57 |
| fenn | you know they would probably fund it if persuaded properly | 01:58 |
| genehacker | oh I know start a cult or something | 01:58 |
| fenn | oops the earlier density values were wrong | 01:59 |
| fenn | actually 8*3*3000 denier + 14*3*1000 denier = 0.012kg/m | 02:00 |
| genehacker | what values | 02:00 |
| genehacker | does that increase the cost? | 02:00 |
| fenn | but that doesn't add up to 9370 kg does it | 02:01 |
| genehacker | do the math | 02:01 |
| fenn | 1266kg | 02:01 |
| genehacker | I'm studying for a test at the moment | 02:01 |
| fenn | did you take chemistry last year? | 02:01 |
| genehacker | no | 02:01 |
| genehacker | I took that 2 years ago | 02:02 |
| fenn | i'm wondering if teaching quantum mechanics in introductory chemistry is normal | 02:02 |
| genehacker | why? | 02:02 |
| genehacker | yeah | 02:02 |
| fenn | well it doesn't seem terribly relevant to most chemistry problems | 02:02 |
| genehacker | why do you ask this? | 02:03 |
| fenn | kanzure was whining about it | 02:03 |
| genehacker | is it that energy shell stuff diagram thing? | 02:03 |
| fenn | uh.. no | 02:03 |
| fenn | it's what you use to generate that diagram | 02:04 |
| fenn | and other stuff | 02:04 |
| genehacker | the spdf stuff? | 02:04 |
| fenn | you know what, nevermind | 02:04 |
| genehacker | or that what's it called diagram with bonds and stuff | 02:04 |
| fenn | did you actually pass chemistry? | 02:04 |
| genehacker | yeah | 02:04 |
| fenn | does "principal quantum number" sound familiar? | 02:05 |
| genehacker | oh yeah | 02:05 |
| genehacker | fuck even had to use that in materials | 02:06 |
| genehacker | it's pretty useful | 02:06 |
| fenn | one of these days i'm going to sit down and figure this stuff out | 02:08 |
| genehacker | for what? | 02:09 |
| fenn | so i don't have to take it on faith that "The wavefunction of the Schrödinger wave equation reduces to the three equations that when solved lead to the first three quantum numbers." | 02:09 |
| fenn | aw man this is just awful.. wikipedia fails at math as usual | 02:13 |
| genehacker | hmmm... to use wikipedia or not to use wikipedia | 02:13 |

| fenn | kanzure: you're baking the surface as well as the pie | 05:24 |
| fenn | the whole affix thing isn't really that important i guess | 05:24 |
| fenn | the point was supposed to be that you merge contexts when you put two things together | 05:25 |
| fenn | but you aren't even keeping track of context | 05:25 |
| fenn | you might say "but i kept the pie together with surface!" but i'd argue that's wrong because you're not supposed to bake the surface | 05:26 |
| fenn | you should put the pie in a new context in order to bake it, see? | 05:26 |
| fenn | and just call it Action ffs | 05:27 |

| fenn | i think i prefer 'operation' instead of 'action' | 05:34 |
| fenn | but something has to perform that operation eventually | 05:34 |
| fenn | the act of being performed makes it an action, i guess | 05:35 |
| kanzure | i usually put a pie in a bowl | 06:05 |
| kanzure | and then bake the pie in the bowl | 06:05 |
| kanzure | guess i wasn't thinkin | 06:05 |
| kanzure | *thinking | 06:05 |
| fenn | but 'surface' isnt a bowl | 06:05 |
| kanzure | that's true | 06:06 |
| kanzure | obviously this needs some work | 06:06 |
| fenn | it's a table which is connecte to a floor which is what the agent is standing on, providing relative positioning | 06:06 |
| kanzure | i think that this is an easy modification | 06:06 |
| fenn | so i don't really care what the surface is, but you can't put the whole kitchen inside the oven | 06:06 |
| kanzure | if you can't stand the heat, don't put the kitchen in the oven? | 06:07 |
| fenn | no, you can't, because the oven is in the kitchen and we have locally flat spacetime | 06:07 |

| AchiestDragon | hi | 14:40 |
| kanzure | ybit: you may be interested in this: http://library.ncrtm.org/AT/RESNA_2007/StudentDesign/Other/Keena.html | 14:40 |
| kanzure | it's a page-turning machine. the designs are sitting in a giant 8 inch binder in front of me | 14:40 |
| AchiestDragon | hmmm interestingly as a solution to a problem its not an effective one ,, ie the pages you may struggle on by hand as you can sort of tell that 2 pages are stuck together , that machine would skip so you could miss a chapter | 14:43 |
| kanzure | we were thinking of debinding books and scanning them | 14:43 |
| kanzure | when you debind them i imagine you'd want to "fan" them. if there is a missing page, you can detect this by OCR of the page numbers (this is about the only thing that you're capable of OCRing) | 14:44 |
| AchiestDragon | well for that application yea ,, but not to hold the book infornt of you and have it turn the pages | 14:44 |
| AchiestDragon | exept ofr disabled use i guess | 14:44 |
| bzSmari | kanzure, why? | 14:44 |
| kanzure | bzSmari: what? | 14:45 |
| AchiestDragon | smme reson a printer may occasionaly take 2 pages though if you had not fanned the paper before putting it in the tray | 14:45 |
| kanzure | bzSmari, AchiestDragon is working on a cnc machine that i thought you might like to hear about | 14:45 |
| bzSmari | kanzure, ah | 14:46 |
| bzSmari | okay | 14:46 |
| bzSmari | I'm actually working on an articulated arm with a thermoplastic extruder on it. | 14:47 |
| AchiestDragon | ftp://adl.serveftp.org/home/achiestdragon/all machine 3d.pdf | 14:47 |
| AchiestDragon | all one link | 14:47 |
| bzSmari | The idea is that a few of these can cooperate. | 14:47 |
| AchiestDragon | big file for one page though | 14:48 |
| bzSmari | user/pass. | 14:48 |
| kanzure | bzSmari: you have an account | 14:48 |
| bzSmari | oh | 14:48 |
| bzSmari | yes | 14:48 |
| kanzure | sigh | 14:48 |
| kanzure | :p | 14:48 |
| AchiestDragon | 7.1mb | 14:48 |
| kanzure | nothing seems to be in there | 14:48 |

| AchiestDragon | the 220Ncm ones with the 10mm shaft about hlaf way down that page are the ones i use | 14:52 |
| AchiestDragon | smaller dia and about the same touqe | 14:52 |
| bzSmari | AchiestDragon, nice! Thanks! | 14:53 |
| AchiestDragon | that machine has a travel of 800mm * 400mm * 300mm (32" * 16" * 12") and should be able to machine aluminium (at about a 4mm square cutting apture) | 14:57 |
| AchiestDragon | so nice things like fully sculptured 19" rack mount pannles could be machined from 20mm thick aluminium plate | 14:58 |
| ybit | interesting things to do with an stm | 14:59 |
| kanzure | ooh. http://www.kirtas.com/ | 15:00 |
| ybit | where can i purchase (or be given freely) neural stem cells? | 15:03 |
| kanzure | carolina probably has some cell lines growing | 15:04 |
| AchiestDragon | what makes me laugh is on 90% of all books printed in the last 20 years are all electonicaly pre pressed so the publisher should still have basicaly a high def pdf of it they could distribute anyway | 15:04 |
| kanzure | right | 15:04 |
| kanzure | bzSmari: do you know if all ODEs are steady state, or if all steady state systems can be described by ODEs? which way around is it | 15:05 |
| ybit | carolina doesn't carry stem cells :P closest thing they have is a video about it | 15:11 |
| ybit | maybe i should contact a few professors asking if they would be willing to share | 15:11 |
| ybit | because it's hard to cultivate them from mice | 15:11 |

| kanzure | feel free to rant about features that you want to see in your codebase | 15:14 |
| -!- Irssi: #hplusroadmap: Total of 37 nicks [0 ops, 0 halfops, 0 voices, 37 normal] | 15:14 | |
| jonathan__ | yup | 15:14 |
| jonathan__ | one next step is creating the database format for the physical object measurements and the vectors for handling the objects. i.e. "griener-96well-plate x,y,z 96 wells" etc | 15:16 |
| kanzure | what's the proper name of the library btw? | 15:17 |
| jonathan__ | either using the datasheet measurements or using the robot itself to measure | 15:17 |
| jonathan__ | just "Robotics" | 15:18 |
| jonathan__ | or perl Robotics | 15:18 |
| kanzure | kinda ambiguous | 15:18 |
| bzSmari | kanzure, no, I don't think all ODEs are steady state... | 15:19 |
| bzSmari | but I might be wrong. | 15:19 |
| kanzure | well i guess search.cpan.org brings it up immediately | 15:19 |
| kanzure | huh | 15:19 |
| bzSmari | I haven't done any ODE stuff for years. | 15:19 |
| kanzure | jonathan__: i opt for hiding away the BS that the manufacturer has used as a protocol, and instead make the internal database and input/output file formats clean yaml | 15:20 |
| kanzure | http://search.cpan.org/~jcline/Robotics-0.22/lib/Robotics.pm | 15:20 |
| * kanzure wonders if jonathan is aware of the emc project | 15:21 | |
| jonathan__ | there's multipple yaml databases.. the internal vendor one, is for the language parsing only, not exposed to user | 15:21 |
| kanzure | no funny business? | 15:21 |
| jonathan__ | the user application will use either "robotic english" to control, or very high level api's. not dependent on vendor concept. the low level robot commands are very scalable. the windows gui scripting language from the vendor is where they messed up and fit everything into a narrow user model. | 15:24 |
| kanzure | can't help but think that you might be re-implementing some emc features | 15:25 |
| kanzure | (for the more general features) | 15:25 |
| AchiestDragon | the main problem with emc is its need for a real time kernel | 15:26 |
| jonathan__ | most software is a re-implementation of something else... | 15:26 |
| jonathan__ | perl robotics is very high level. the robot does all the real time. | 15:27 |
| AchiestDragon | just makes it a bit impractical where the pc controling the cnc is usualy the same machine you would use for cad , and other desktop stuff , | 15:27 |
| jonathan__ | it could be that perl robotics sits on top of all that other stuff | 15:27 |
| jonathan__ | exactly, the primary goal of using perl is easy client/server protocol to the local PC | 15:28 |
| AchiestDragon | well there is a emc related hardware and software problem that needs to be addressed | 15:28 |
| -!- any22697338 is now known as katsmeow | 15:29 | |
| jonathan__ | ? | 15:30 |
| AchiestDragon | ok so as it stands its set for stepper motor opperation ,, to make fast machines you do away with steppers and use dc motors with optical encoders | 15:30 |
| katsmeow | of course | 15:30 |
| AchiestDragon | theres no opensource dc motor stepper simulation drivers | 15:31 |
| katsmeow | prolly very low duty cycle, high current, little gearing | 15:31 |
| katsmeow | all motors are diferent | 15:31 |
| AchiestDragon | well think say a 36v dc electric scooter motor ,, like 10A and 300W would give you a high feed rate sort of like 12" per second | 15:32 |
| katsmeow | that would be a lot of torque | 15:32 |
| katsmeow | i assume you mean to ramp it up to max rpm as well | 15:33 |
| katsmeow | 300watts is nearly 1/2 hp | 15:33 |
| AchiestDragon | ideal sort of speed for routing pcbs , but would need something faster and with a bit more power than a dremil at the end | 15:33 |
| katsmeow | yeas, a plunge wall zip-tool | 15:34 |
| AchiestDragon | even a 500w router would be a bit low | 15:34 |
| katsmeow | think so? | 15:34 |
| AchiestDragon | maybe 2 or 3hp at that feed rate min | 15:34 |
| katsmeow | will a .035 bit take a hp? | 15:34 |
| AchiestDragon | if the hp is in the form of speed well just | 15:35 |
| katsmeow | hmm, ok | 15:35 |
| AchiestDragon | but it would be close to the point where the bit would fall apart at that rpm | 15:35 |
| katsmeow | i was going to use a 18v Ryobi zip-router thing | 15:37 |
| katsmeow | it has a 1/4 collet, comes with a 1/8 as well | 15:37 |
| katsmeow | and it's reversable, for easier automated bit changes,maybe | 15:38 |
| kanzure | apparently adl.serveftp.org/dokuwiki/skdb is blocked to peeps in the DOD network | 15:38 |
| katsmeow | kanzure, do we pretend that's a bad thing? | 15:38 |
| kanzure | we pretend it's funny :) | 15:39 |
| katsmeow | ok :-) | 15:39 |
| katsmeow | i picked up 10 gigabytes of 10ns or faster 32kx8 rams , which i hope to hook to avr and other small beasts, for $54 | 15:40 |
| katsmeow | i think i therefore may also be getting an addtional 3gig for free later | 15:41 |
| bzSmari | I'm off. | 15:41 |
| AchiestDragon | my exisiting cnc uses a 500w bosch router that has a 1/4" collet and does about 27,000 rpm | 15:41 |
| katsmeow | that's ~12 cents / chip , i think | 15:41 |
| AchiestDragon | it needs a 120 to 240 ipm feed rate on 20mm thick ply | 15:42 |
| katsmeow | AchiestDragon, i was merely gonna drill holes in a not-hurry in pcb | 15:42 |
| kanzure | hm, someone sent an email to the chem class saying "e=mc^2 is not the correct answer to the homework". i tend to concur and will be spending a link out to the timecube soon.. heh. | 15:42 |
| katsmeow | i figured the 18vdc would be easy to make and control | 15:43 |
| AchiestDragon | you would be supprised how slow they can be though ,, when using steppers the steppers may only be able to give you a feed rate of about 30ipm if using 1.5mm pitch threaded bar as leadscrews | 15:43 |
| AchiestDragon | also if you have the feed rate too low then you get schorching on wood and if doing plastic you find it starts to half machine and half melt out whatever your cutting | 15:45 |
| katsmeow | if you want speed and accuracy, use $60 HF 12inch calipers for position, and dc motors for driving the screws, and let 'er fly | 15:45 |
| AchiestDragon | sattelite jacks have quite good qualaty screws in them £27 for a 10" and £60 for a 24" they do other sizes also | 15:47 |
| katsmeow | <customer> hi tech support, the allthread on my reprap is getting so hot the oil is smoking, is this normal? | 15:49 |
| AchiestDragon | well anyway i finished that drawing on wednesday this week and started to think about a smaller machine for just pcbs and platics ,, made the frame yesterday and made the gantry and carrage for it today | 15:50 |
| kanzure | steve recommends McNerney et al "The Role of Design Complexity in Technology Improvement". | 15:54 |
