14:34 MrCurious news just said
14:35 MrCurious lets all put on our surprised faces that life on earth is in danger...
14:54 LoRez you building a robot to fix that particular problem or just venting in random places where it's not really on topic?
14:56 MrCurious hadnt thought of a garbage scooping robot for th ocean
14:56 MrCurious but probably more just heralding the end of the species... i.e. venting
19:53 JEntrep how come there isn't a channel dedicated to drones/quadcopters/uavs/UAS
19:53 JEntrep ??
19:53 JEntrep That seems really weird
19:53 GargantuaSauce there are several
19:53 JEntrep I couldn't find any on channels like #drones or #uav
19:54 GargantuaSauce they are all centred around specific flight controller project
19:54 GargantuaSauce s
19:54 JEntrep I am looking for basic tips on building a quadcopter from scratch
19:54 JEntrep ah ... specific UAS projects?
19:54 JEntrep I would like to design my own UAS software
19:54 JEntrep Would anyone here have any ideas on building a quadcopter from scratch?
19:54 JEntrep As far as I can tell it's 100% motor control
19:55 JEntrep Would that be a fair assumption?
19:55 JEntrep Just control the 4 motors turning the propellers?
19:55 GargantuaSauce "just"
19:56 JEntrep hardware wise I mean
19:56 JEntrep the rest is software control right?
19:56 JEntrep the UAS
19:56 GargantuaSauce well you need sensors
19:56 GargantuaSauce communication
19:56 ace4016 more or less, assuming you're not fabricating the parts
19:57 JEntrep not if i use sensorless Field-Oriented Control :)
19:57 GargantuaSauce good luck determining your orientation with that
19:57 JEntrep Yeah the motors have a power distribution + communication connection?
19:57 ace4016 i think the sensors are more for knowing how far off the ground you are, how you're oriented, etc,
19:58 JEntrep Well those are just IC sensors then
19:58 JEntrep can be attached to the main board
19:58 ace4016 possibly
19:58 JEntrep I mean I guess you could make a distributed control system and implant a tiny mc on each motor :P
19:59 GargantuaSauce every implementation i've seen has dedicated micros for motor control
19:59 JEntrep but i also need battery recommendations
19:59 ace4016 li-po iirc will be your lightest bet
19:59 JEntrep yeah i may have to look at TI or such for motor control chips
19:59 GargantuaSauce lipo is basically the only choice
20:00 GargantuaSauce and the specific battery capacity/voltage depends on the rest of the specifications
20:00 ace4016 unless you go chemical based generator :P
20:00 JEntrep Should just stick my phone on the damn thing :P
20:00 ace4016 ICE type generator
20:00 JEntrep ICE??
20:00 ace4016 internal combustion engine
20:01 JEntrep how small can those get?
20:01 ace4016 there exist model planes and helos, right? :P
20:02 GargantuaSauce anyway it sounds like you need to do some serious research before you go asking people for specific advice
20:02 JEntrep I think those military drones run on petroleum
20:02 JEntrep D:
20:02 JEntrep What kind of research?
20:02 JEntrep That is what I am asking for!
20:02 GargantuaSauce like understanding the basic components of a contemporary quadcopter.
20:03 JEntrep That's what I am ASKING ABOUT!
20:03 ntrep is conf
20:03 GargantuaSauce and i'm telling you to google it because none of us are specialists in that domain and nothing we say will be anything but googles
20:04 ntrep likes da goo
20:04 GargantuaSauce i'd refer you to one of the aforementioned channels related to specific fc projects but they don't take well to neophytes who haven't done any homework
20:04 JEntrep >_>
20:05 ace4016 also, is your goal a quadcopter or a quadcopter based off of a certain design?
20:05 ace4016 is this more to practice controls, or for fun, etc.?
20:05 JEntrep my goal is actually a testload for a new UAS xD
20:06 JEntrep I guess techincally I could just use a software simulator for that :P
20:06 ace4016 -_^
20:06 JEntrep But i highly doubt there are any good ones
20:06 JEntrep thus why i would rather just get my hands dirty
20:06 JEntrep having the ability to optimize hardware concurrently will be nice
20:06 ace4016 could buy a quadcopter that's reprogrammable or modifyable :P
20:06 GargantuaSauce optimizing is a long way down the road
20:07 GargantuaSauce just getting something off the ground is hard enough
20:07 JEntrep ^ :(
20:07 ntrep cris eve
20:07 GargantuaSauce start with something run-of-the-mill
20:07 GargantuaSauce there are some very good tutorials on building typical ones out there
20:07 ace4016 otherwise, look up designs online, or pull out your systems engineering hat and break down the problem into smaller problems/systems
20:07 JEntrep Well my first QC was gunna be UBER simple :P
20:08 JEntrep Yeah, that was my plan ace
20:08 JEntrep First build something simple .. break it down ...and optimize more locally
20:08 JEntrep ;)
20:08 JEntrep ace sounds like a pilots username
20:08 JEntrep You wann fly my quadcopter? :3
20:08 JEntrep *wanna
20:09 JEntrep hopefully you weigh less than 3 pounds
20:09 JEntrep well some googles will do me some good
20:09 GargantuaSauce i don't think a human could manually maintain the stability of one
20:09 JEntrep Off to Google-Land I go
20:09 ace4016 i do like flying and space machines, and do work in the aerospace industry :P
20:10 JEntrep sweet! :D
20:10 JEntrep GargantuaSauce, Humans barely maintain the stability of big copters :P
20:11 ace4016 they can barely do flying wings too :P
20:16 JEntrep Are there any open source projects being headed up by this channel? :
20:16 JEntrep :)
20:17 JEntrep i'll bbl
20:17 JEntrep if there aren't any projects ... then i am wanting to know: why not?
20:18 JEntrep hmmmmmmm?!?
20:18 JEntrep :P
20:23 MrCurious impressive use of active IR camoflage.... http://foxtrotalpha.jalopnik.com/is-polands-stealthy-pl-01-the-tank-of-the-future-1554395391
20:25 GargantuaSauce the barrel shroud looks so fucking cool
20:26 robotustra_ T-90 is better
20:26 robotustra_ and I don't really think Poland need this tank
20:27 GuShH_ robotustra: russian envy!
20:27 robotustra_ I'm Byelorusian, stupid guy
20:28 GargantuaSauce ussr envy
20:28 GuShH_ haha
20:28 robotustra_ byelorussians do not do they own tanks
20:28 GuShH_ robotustra: yes we know you are highly radioactive.
20:28 GuShH_ that's why we only touch you with lasers.
20:28 robotustra_ I was absent in belarus that time
20:28 robotustra_ so I don't
20:28 GuShH_ anyway if you made all tanks look like regular vehicles through IR, you would just target regular vehicles anyway... it's war.
20:29 robotustra_ of cause
20:29 robotustra_ tank is TOO huge to hide on battle field
20:29 robotustra_ they just waste money for nothing
20:29 robotustra_ and they ha HUGE head lights
20:29 GuShH_ well this is for night-time, the IR deal.
20:30 GuShH_ you don't use headlights on tanks at night
20:30 robotustra_ it's not a comuflage anymore
20:30 GuShH_ robotustra: IR search lights you mean?
20:30 robotustra_ no
20:30 GuShH_ you give away your position if you them.
20:30 robotustra_ head lights
20:30 GuShH_ tanks do not need headlights during combat or transport at night
20:31 GuShH_ maybe russians do, since they probably don't even have nighvision.
20:31 GuShH_ let alone any type of radar.
20:31 robotustra_ no it doesn't
20:31 GuShH_ they probably just pop their heads out and ask "is there anyone here?"
20:32 robotustra_ and the second thing is about poland - they never did goog steel
20:32 robotustra_ so that's why they try to hide their tanks
20:32 ShH_ idly cloaks and hides in robotustra's cl
20:32 robotustra_ good
20:32 ShH_ is currently cloaked as a double ended dildo, matched from robotustra's fine collec
20:33 GuShH_ haha "russian steel is stronger"
20:33 GuShH_ I'd rather have less steel, with the right angles, than more steel, with the wrong angles.
20:33 GuShH_ and less steel means less weight.
20:33 MrCurious maybe poland makes tank to sell to ukrane
20:34 robotustra_ http://www.google.ca/imgres?imgurl=http%3A%2F%2Fkhongthe.com%2Fwallpapers%2Fabstract%2Frussian-t-90-tank-207763.jpg&imgrefurl=http%3A%2F%2F1ms.net%2Frussian-t-90-tank-207763.html&h=1080&w=1920&tbnid=6mvnCnUBVOstiM%3A&zoom=1&docid=krNkUO7zzQPUEM&ei=fBM6U_eWFYqTyQG_kICQAg&tbm=isch&ved=0CKIBEIQcMBM&iact=rc&dur=1191&page=2&start=10&ndsp=14
20:35 MrCurious is ugly...
20:35 robotustra_ russians do not need IR invisibility because they always attack
20:35 robotustra_ it's ugly but works the best
20:35 GargantuaSauce can a tank attack a cruise missile?
20:36 robotustra_ what is cruise missile?
20:36 GuShH_ russians have disposable conscripts
20:36 GuShH_ just dumb inbreds with lead throwing sticks.
20:38 GuShH_ anyway I wants me some peltier covered cars!
20:38 robotustra_ Khalashnikov already showed to the whole world who does the best weapon
20:38 robotustra_ at this point we can close the discussion
20:39 GuShH_ hahaha if you want obsolete weapons, sure.
20:39 GuShH_ like I said, inbred technology.
20:39 robotustra_ let Poland make a good shild steel for tanks
20:40 robotustra_ head shild
20:41 robotustra_ GuShH_: you just envy
20:43 robotustra_ WW2 showed that Tigers and Leopards are shitty shit
20:43 robotustra_ so, the most tech developed country like Germany failed on battlefield
20:46 MrCurious germany used to rule the tank field...
20:46 MrCurious nearly crushed russia who was saved by snow
20:46 robotustra_ Americans did their fail with tanks during the "tempest in desert"
20:47 robotustra_ MrCurious: the plan of gremans was to take russian in 1 year
20:47 robotustra_ but they failed to do this in 5 years
20:47 GargantuaSauce why the hell are you trying to compare WWII dick length
20:47 robotustra_ and true, they were not prepared for russian winter
20:48 robotustra_ GargantuaSauce: because nothing has changed since that time
20:48 MrCurious i am just trolling sorry. i thought the IR camoflage tech was rather cool
20:48 robotustra_ may be. but not for tank I think
20:48 MrCurious 2nd video shows best
20:49 robotustra_ it's more cool for people
20:50 GuShH_ GargantuaSauce: russians are always comparing their dicks
20:50 robotustra_ oh, I thought it niggers who have bigger dicks
20:50 GuShH_ they are also the leading ugly-people porn creators.
20:51 GargantuaSauce oh oh i think i have an imagemacro for this
20:51 robotustra_ I whould never kompare my dick even with a nigger boy
20:51 GargantuaSauce http://xn--d-bga.su/gr.jpg nsfw
20:51 ShH_ sh
20:52 robotustra_ is it you from right side?
20:52 GargantuaSauce yes obviously
20:52 robotustra_ are you mixing right and left
20:52 robotustra_ ?
20:55 robotustra_ http://www.aljazeera.com/mritems/Images/2012/7/20/201272063553965734_20.jpg
20:58 robotustra_ oh, may be I have to make my eyes looking in IR
20:59 robotustra_ or AI which can detect WTF things on battlefield and spot them
20:59 robotustra_ lite PL-01
20:59 robotustra_ like
21:00 robotustra_ <GuShH_> they are also the leading ugly-people porn creators.
21:00 robotustra_ I see you are experienced
21:01 GargantuaSauce you are really grasping at this point arent ya
21:01 GuShH_ lol
21:01 GuShH_ robotustra: totally
21:03 robotustra_ https://www.youtube.com/watch?v=3ivaQf1jns0&list=PLhL3QyBvkbFLcMbuDqboytzn84kBT293r
21:03 robotustra_ really cool and creepy
21:05 GuShH_ not that again..
21:05 GuShH_ MrCurious is probably still fapping to that robot
21:06 robotustra_ oh, sorry
21:07 MrCurious that bot is ilke a week old
21:07 GuShH_ eek https://www.youtube.com/watch?v=oqazH93RqH0&list=PLhL3QyBvkbFLcMbuDqboytzn84kBT293r
21:07 GuShH_ MrCurious: nevertheless robotustra is clearly heading toward that direction and getting rid of his wife in the process.
21:07 MrCurious to be honest... i didnt see strippers losing their jobs to robots...
21:08 MrCurious window washers... accountants yes
21:08 MrCurious strippers no
21:08 GuShH_ this is dumb...
21:08 MrCurious why, would you prefer a different masque?
21:09 MrCurious what if the fembot was working a lathe?
21:09 MrCurious would that change things...
21:09 GuShH_ no, the "face changing robot"
21:09 MrCurious that has been around a few years i think
21:09 GuShH_ I'm sorry I'm not a youtube whore, I hardly watch anything other than a few channels there
21:10 GargantuaSauce it's just a projector inside a matte face profile isnt it
21:10 GargantuaSauce it's a cool idea
21:10 GuShH_ it is
21:10 GuShH_ but it's a dumb looking form.
21:10 GuShH_ they surely used robotustra's face for the mold?
21:11 ShH_ h
21:12 GuShH_ Workaholics should be on every day.
21:12 robotustra_ it looks more like your ass profile
21:12 GuShH_ It clearly does!
21:13 GargantuaSauce workaholics got kind of intolerable after the first season, i found
21:13 robotustra_ I don't like an idea of such technology
21:13 GuShH_ all seasons are the same...
21:13 robotustra_ it's shortcut
21:13 GuShH_ robotustra: but don't be jealous your ass can too change skin colour with a swift motion
21:14 GuShH_ GargantuaSauce: then again I don't smoke, I think that's a requirement for these shows
21:14 GuShH_ if the previous season had twice as many episodes, I guess it's doing well
21:14 robotustra_ GuShH_: you are idiot, but I don't care
21:14 GuShH_ robotustra: Hrmm...
21:15 robotustra_ I'm getting old
21:15 GuShH_ Yes, it's about time you finish your robot before you become carbon dust.
21:15 GuShH_ MrCurious: will you include the mill once I get one? or will you always talk about lathes?
21:15 robotustra_ do you really think you'd told something clever?
21:16 GuShH_ I don't know man, I become less smart every time I read one of your sentences.
21:16 ShH_ idly drools the keyb
21:16 robotustra_ ok, when we will see something from you
21:16 ShH_ w
21:16 GuShH_ buy me a drink first
21:16 robotustra_ I promised moving eyes and I did it
21:16 GuShH_ I promised nothing
21:17 GargantuaSauce delivered!
21:17 robotustra_ to yourself?
21:17 GuShH_ sure
21:17 robotustra_ ok
21:17 GuShH_ I'm busy making space at the garage for a knee mill
21:17 robotustra_ so don't criticise somebody work than
21:17 GuShH_ can't be bothered with any project.
21:17 GuShH_ I did?
21:17 robotustra_ constantly
21:17 GuShH_ I haven't.
21:18 robotustra_ ok
21:18 GuShH_ Quit being a whiny bitch.
21:18 robotustra_ prove that you are clever with your hands
21:18 GuShH_ Again, buy me a drink first.
21:18 robotustra_ after you prove it
21:18 robotustra_ or deserve
21:18 ShH_ calls his
21:19 robotustra_ I'm 40 now and can upbring you, sorry
21:19 GuShH_ lol
21:21 GuShH_ robotustra: I seriously can't recall any criticism toward your project...
21:21 GuShH_ I might need Arnie's help for a total recall though.
21:21 GuShH_ Either him or his maid.
21:23 GuShH_ GargantuaSauce: you reckon it's simply using uv coordinates to deform the skin texture or is there some clever projection going on?
21:24 GargantuaSauce it'd definitely be perturbations in software
21:24 GargantuaSauce way too nonlinear for optics to handle decently
21:25 ShH_ places the geiger counter near robotu
21:26 rue_bed oh damnit
21:26 rue_bed I heard there is an industral robot arm at the recycling centre
21:26 rue_bed armyofevilrobots, hey
21:27 rue_bed who can get there first
21:27 rgantuaSauce books a fl
21:27 rue_bed the venture way plate
21:27 rue_bed plave
21:27 rue_bed place
21:27 GuShH_ haha
21:27 GargantuaSauce oh that reminds me
21:27 rue_bed I worked till 5 today anyhow
21:27 GargantuaSauce i've decided to apply at UBC for a masters next sept
21:27 GuShH_ rue_bed: hurry!
21:28 GargantuaSauce so we are eventually going to be not-quite neighbours! woo.
21:28 rue_bed you can come bother me on the weekends
21:28 rue_bed :)
21:30 GargantuaSauce more like every day
21:31 GuShH_ This is his master plan to gain access to your tools
21:31 GuShH_ Through "friendship"
21:32 GargantuaSauce i suspect if i end up at the robotics and control lab there i'll have access to all the toys i want
21:33 GuShH_ MrCurious: 1/4" wood router bits are generally smaller than 1/2" or can I find big panelling bits anyway? coves and such
21:33 GuShH_ seems all the cool stuff is in 1/2"
21:33 robotustra_ chinese people will replase real people with that bot's like this https://www.youtube.com/watch?v=hEJwvvQnP2w
21:34 robotustra_ rue, you did a pneumatic muscle 2 years ago, where is your robo arm?
21:35 GuShH_ up the arse of the last guy who asked
21:36 GargantuaSauce i am so glad i have done enough visibly to be immune to these probing questions
21:36 robotustra_ no, I'm just curious
21:37 robotustra_ sometimes it's better to see sombodies else progress to make my own
21:37 GargantuaSauce yeah i agree
21:38 GargantuaSauce oh yeah my dry film arrived today!
21:38 GargantuaSauce i tried the photoresist paint the other day and it fucking sucks
21:38 GargantuaSauce though i know i just did it wrong
21:38 GargantuaSauce hard to handle properly, spread evenly, develop the right amount, etc
21:39 GargantuaSauce anyway now that the film's here maybe i'll get a pcb happening by the end of the week
21:39 GargantuaSauce i should have bought a red led strip or something so i can be sure my work lighting isn't exposing the photoresist
21:40 GuShH_ robotustra: is that what a gay asian sounds like?
21:40 JEntrep Told ya I would be be back bitches ;P
21:40 GargantuaSauce JEntrep: because we're all doing our own shit
21:40 JEntrep D:
21:40 GargantuaSauce and organizing these assholes is a task that none of us are up to
21:40 JEntrep again
21:40 JEntrep D:
21:41 JEntrep you don't need to organize
21:41 JEntrep that is what git and github are for
21:41 JEntrep :P
21:41 GargantuaSauce to all work on one project?
21:41 GargantuaSauce are you on drugs
21:41 JEntrep maybe ._.
21:41 Tom_itx how else can one survive?
21:42 JEntrep how can computer science be around all these decades
21:42 JEntrep and yet we still can't put together a bloody software team easily
21:42 JEntrep FFS!
21:42 GargantuaSauce because software is literally the hardest thing we've ever approached
21:43 JEntrep nope
21:43 JEntrep that's called woman
21:44 ntrep wins with myso
21:44 GuShH_ robotustra: https://www.youtube.com/watch?v=L3gE1Zp9Vt8
21:44 JEntrep *misogyny
21:44 JEntrep woops
21:45 JEntrep is google gunna buy siemens next?
21:46 GargantuaSauce animatronics doesn't approach any of the hard problems of robotics
21:46 GargantuaSauce it's just smoke and mirrors
21:46 GargantuaSauce as an artistic endeavor it's damn cool but it's hardly producing smarter machines
21:46 GargantuaSauce just ones that look creepier
21:47 JEntrep it was a joke
21:47 GargantuaSauce also siemens is huge, google couldnt buy them if they wanted to!
21:47 JEntrep siemens does a lot more than animatronics :P
21:47 JEntrep also ... what is siemens doing giving a demonstration on the brain?? O_o
21:48 JEntrep they aren't a neuroscience company
21:48 GargantuaSauce they do imaging
21:49 GargantuaSauce http://www.healthcare.siemens.com/magnetic-resonance-imaging/mr-pet-scanner/biograph-mmr
21:49 GargantuaSauce that head is marketing for this
21:49 GargantuaSauce it's right there in the description
21:49 GuShH_ robotustra's head is more animatronics than robotics...
21:49 GargantuaSauce this is what i'm getting at when i say you need to do basic research!
21:49 GargantuaSauce oooooh shots fired.
21:53 robotustra_ <GuShH_> robotustra: https://www.youtube.com/watch?v=L3gE1Zp9Vt8
21:53 robotustra_ good job
21:53 robotustra_ I have to repeat such thing for my robo head this summer
21:54 robotustra_ I still don't know what silicon to use for such molding
21:55 JEntrep silicon?
21:56 JEntrep I am guessing its some sort of silicon-dioxide based gel?
21:56 JEntrep Like what they put in breast implants?
21:56 JEntrep probably has to be heated to be molded
21:56 robotustra_ sort of
21:56 robotustra_ no, it's not to be heated
21:57 robotustra_ it's just solidify with some hardener
21:57 robotustra_ but still should be as soft as real skin
21:57 GuShH_ silicone
21:58 robotustra_ yep
21:59 robotustra_ and I whould like it to be washable
21:59 robotustra_ because normally silicone is very steaky
21:59 robotustra_ to dust
22:00 armyofevilrobots rue_bed: ping
22:00 armyofevilrobots Where is that recycling center? I'll go first thing in the am.
22:00 robotustra_ I received 12VDC lipo today
22:00 robotustra_ with power meter
22:01 robotustra_ will play thes weekend with it
22:01 robotustra_ measure eyes power consumption
22:02 GargantuaSauce sneak in at 3 in the morning and run off with the arm
22:02 GuShH_ I guess it weighs quite a bit
22:03 GuShH_ plus those places are like this guy's second home
22:07 MrCurious !bs
22:09 MrCurious if you take 3 seperate ai's or alien species, and advance them far enough technologically, to where each can engineer their own genes... would they independently arrive at a similar or identical solution to perfecction?
22:09 GargantuaSauce probably pretty divergent
22:09 MrCurious intermediate steps may be, but i think they would converge
22:10 GargantuaSauce maybe after a bunch of iterations
22:10 GargantuaSauce well
22:10 GargantuaSauce the answer will likely be found if we find alien life
22:10 MrCurious yes. i am asking about the point where they all stop tinkering and announce done!
22:10 GargantuaSauce will they ever?
22:10 GargantuaSauce wouldn't that be pretty stupid?
22:10 MrCurious tough call. my brain is not big enough to answer
22:11 GargantuaSauce life itself does the process irrespective of conscious effort right
22:11 GargantuaSauce i would almost say the reengineering would be irrelevant except for accelerating it
22:11 GargantuaSauce it would be a question of exploring the solution space to find an optimal arrangement for the present situation
22:11 MrCurious interesting side question is would infinite life or finite life be prefered after enough iterations to reach and test both
22:12 GargantuaSauce if you can constantly grow, your present situation will be changing constantly
22:12 MrCurious or planned situation, limited only by physics
22:12 GargantuaSauce you'd race through the process of applying more and more energy
22:12 GargantuaSauce and the world would look astonishingly different at each stage
22:12 GargantuaSauce from using all the energy of a planet, to a star, to a galaxy....
22:14 JEntrep I like how this channel is still one of the few good freenode channels :P
22:15 MrCurious what do you mean?
22:15 JEntrep anyways
22:15 JEntrep I'm outies :P
22:15 ntrep puts on sunglasses and e
22:15 JEntrep bitches
22:15 MrCurious now we shall never have the answer!

22:17 MrCurious interesting
22:17 robotustra_ it's too far future
22:18 MrCurious i suppose i am asking in a way who is god, and when do we make him. or was god made before life, or does life give rise to the creation of god
22:18 GargantuaSauce says he whose AI plans are a kurzweil-fellating idea
22:18 MrCurious wow, and this is only 1 beer in...

22:20 ShH_ fetches one of MrCurious' b
22:20 rue_shop2 armyofevilrobots, get my message about the robot at gibsons recycling/
22:20 armyofevilrobots I did. How much? :)
22:20 armyofevilrobots and what kind?
22:21 rue_shop2 I dont know
22:21 GargantuaSauce armyofevilrobots: modern web applications have shown that that isn't a big deal
22:21 rue_shop2 I was just told today, I'd hoped to make it home before 5 to check it out, but I was still in sech 5:15
22:21 GargantuaSauce they basically all sacrifice consistency, instead allowing changes to propagate between nodes over time
22:21 rue_shop2 I hear its industrial, 3' ish
22:21 GargantuaSauce and it works just fine
22:21 rue_shop2 with manual
22:21 rue_shop2 but I think thats 4th hand
22:22 rue_shop2 8| a skate board bearing is a press fit into a 1/2" pvc coupling
22:22 GuShH_ what's a skateboard bearing? 608?
22:22 rue_shop2 yea
22:23 GuShH_ they are half inch od!
22:23 rue_shop2 haha hahaha
22:23 ShH_ checks
22:23 rue_shop2 this puts an interesting light on the hobby servo arm I was thinking of throwing togethor
22:24 GargantuaSauce i actually have started considering that sort of construction for 3d printed parts
22:24 GuShH_ wait 608 are about 1 inch od from memory
22:24 GargantuaSauce after pondering all sorts of fancy bearing capture designs
22:24 GuShH_ bah I need a beer.
22:24 GargantuaSauce instead just having a hole to press fit them into
22:24 GuShH_ a pocket! POCKET.
22:24 rgantuaSauce considers the prospect of getting his fucking reprap working again for the 1812696th
22:25 GuShH_ it shall work for as long as you babysit it
22:25 GuShH_ I once posited this is how the zombie apocalypse begins.
22:25 GuShH_ reprappers will eventually turn into zombies.
22:25 GargantuaSauce well what i need to do is abandon the notion of having 3 extruders
22:26 GargantuaSauce the firmware they wrote for that on top of marlin is ridiculously bad
22:26 GuShH_ isn't most of their software bad?
22:26 GargantuaSauce yes but this takes the cake
22:27 GuShH_ I could use some cake.
22:27 GargantuaSauce me too
22:30 MrCurious the cake is a lie...
22:31 rue_shop2 oops, too tight, it snapped
22:31 armyofevilrobots @rue_shop2; awesome. I wanted to make a chainsaw bot for some time :D
22:32 GuShH_ lol
22:32 GuShH_ what could possibly go wrong
22:32 armyofevilrobots My spare chainsaw threw a chain the other day, so surprising things perhaps.
22:33 rue_shop2 21.5mm vs 22mm
22:33 GuShH_ I've never seen a chainsaw throw a chain, derail sure.
22:33 rue_shop2 armyofevilrobots, hmm I have to race ya for it?
22:33 MrCurious chain saws for pincers...
22:33 rue_shop2 I wonder what it is
22:33 armyofevilrobots the pin in the bearing on a link snapped out of one of the side plates. Blew the chain off.
22:34 armyofevilrobots It was buried in a log at the time, so kinda anti-climactic.
22:34 GuShH_ dayum
22:34 armyofevilrobots rue_shop2: I'll head out at their opening time if you can't make it. Would love to collab on a project of some kind.
22:34 armyofevilrobots Strangely, I have a friend that is giving me a small robot arm right now as well.
22:36 rue_shop2 I dont know if I'm in gibsons or sech tommorow for work, prolly sech
22:36 rue_shop2 love to know more about it
22:38 rue_shop2 I shouldn't get too excited, I know where there is a welding robot tucked into a sea can that it just barely fits into kneeled all the way down
22:38 rue_shop2 that I think I'd be allowed to play with
22:38 armyofevilrobots Cools.
22:39 armyofevilrobots One day: https://www.youtube.com/watch?v=bxbjZiKAZP4
22:40 rue_shop2 I think doing that goes against page 1 of the safety manual
22:42 GargantuaSauce that is danger.
22:42 GargantuaSauce one errant button press away from being mashed into the floor like a roach
22:42 GuShH_ shut up and press the button
22:44 rue_shop2 damn, these bearings have so much slop
22:44 GuShH_ rue_shop2: did you buy them from eBay?
22:45 GuShH_ mine seem trashed, but that's how they come from the tube... shitty quality
22:48 rue_shop2 no, their bulk from the sports shop
22:49 GuShH_ but they probably are generic china brand
22:50 rue_shop2 $1 ea
22:50 GargantuaSauce heh
22:50 GuShH_ no brand?
22:51 rue_shop2 abec-7
22:52 GuShH_ seems that's the tolerance rating, not the brand
22:52 GuShH_ abec-NaN from what you described :P
22:52 GargantuaSauce if they're $1 at the sports store they're made to last a week on a kid's skateboard before he fills them with grit
22:53 GuShH_ hah
22:53 GuShH_ the Italian SKF I put in the angle grinder still works fine, I can't find any more play than it initially had.
22:53 GuShH_ the factory bearing was almost shot
22:54 GuShH_ that has to be one of the major differences between the most expensive grinders and a cheaper model, the bearings.
22:54 rue_shop2 http://www.youtube.com/watch?v=YU3vraleH0I
22:55 rue_shop2 ok I made a better base than that... next...
22:55 GuShH_ look at it, jittering it's way through life!
22:56 GuShH_ that's an interesting application though
22:57 GuShH_ the last graph is interpolated I guess
22:58 GuShH_ rue_shop2: what's your end goal for the arm?
22:58 GargantuaSauce that's cool
22:58 GargantuaSauce i guess i have a couple magnetometers kicking around, should give that a shot
22:58 rue_shop2 I just want to throw togethor a scrap arm without getting too carried away
22:58 GargantuaSauce hahah
22:59 GargantuaSauce as if you havent already failed that 10x over
22:59 GuShH_ :o
22:59 GargantuaSauce (pot, kettle, black, etc)
23:00 GargantuaSauce there are 6 discrete projects on my workbench
23:00 GuShH_ there are none on mine
23:00 GuShH_ I win
23:01 GuShH_ It means I either finished all of them or I never committed to any project!
23:01 GuShH_ Wait, does -any- work surface count?
23:01 GargantuaSauce not your mattress
23:02 GuShH_ there are parts for an electrode EDM toy sitting on top of my wood lathe, I guess that counts
23:02 GargantuaSauce yeah
23:02 GargantuaSauce man i was pretty pleased with that joke, way to not humour it
23:03 ShH_ facep
23:03 ShH_ is NOT a gi
23:06 GuShH_ your average reprap photo http://forums.reprap.org/file.php?1,file=3612,filename=Picture_009.jpg
23:07 GargantuaSauce looks like interesting weather
23:08 GargantuaSauce speaking of which, it sounds like the ice pellets are desperately trying to invade my home
23:08 GargantuaSauce there's a pretty significant accumulation of them now
23:08 GargantuaSauce and it's weird, very different from snow
23:08 GargantuaSauce not very common that we get quantities of pellets like that
23:11 GuShH_ are you positive those aren't M&Ms?
23:12 GargantuaSauce no they are cold and untasty
23:12 GargantuaSauce walking through them in the wind feels like being bombarded with little daggers
23:21 rue_shop2 yes, having a shop with a pile of misc pipe fittings and a lathe is a good thing
