00:00 theBear i was more than a little surprised :)
00:02 GuShH heh
00:32 theBear ooh dear, i feel lightheaded
00:39 rue_house move back form the monitor a bit
00:40 theBear i can't move :(
00:41 theBear i wonder.. never met any of my female neighbors, but maybe i should ask one to undress me so i can have a shower
00:41 rue_house so your condiiton isn't getting better
00:42 theBear this week is the worst ever and not showing signs of improving... pretty much as bad as anything back related can possibly get
00:42 theBear i'm days away from finding a wheelchair, it's REALLY bad
00:44 GuShH theBear: you should comission rue_house to build you a robochair
00:44 theBear i don't want a fucking chair ! i wanna walk :(
00:44 GuShH but, it's got rocket launchers
00:44 theBear that does sound kinda cool
00:45 theBear i could use them to vanquish my foes
00:47 theBear where's my damned chauffeur today ? i need him !
00:49 rue_house you cant move or moving cuases crippling pain?
00:49 theBear mostly the 2nd one
00:50 rue_house http://www.ebay.com/itm/Magnetic-Magnet-Door-Sensor-Alarm-GSM-Sound-activated-Monitor-For-Home-Security-/160853540364
00:50 rue_house I thought the sign said, "I'm with stupid"
00:50 theBear and i taken more than the ER gives you by a long way... barely touches the edges
00:50 rue_house you can come to canada and smoke pot
00:51 theBear thanks but umm, i can barely get to the front door, during the good hours
00:51 rue_house but our doctors are incompitent too
00:51 theBear doesn't matter, there's nothing medical science can do for me at the moment
00:52 rue_house too bad you cant help me build an MRI scanner
00:52 theBear meh, i got pictures from them, only says i'm crippled and can't be helped
00:53 rue_house what is the problem? disc screwed up?
00:53 theBear all discs screwed up, extra 'rib' inside my hip bones from birth, back bones been grinding on each other for too many years.... the whole thing is screwed
00:54 Gargantuasauce how do you plan on building an mri machine
00:54 theBear and of course nerve damage/hypersensitivity caused by a couple years of it all being chronic
00:54 rue_house part of the hip or just ratteling around in there?
00:54 Gargantuasauce going down to the liquid helium store on the way back from the superconductor supermarket?
00:55 rue_house Gargantuasauce, I cant take you seriously when you say that sounding like donald duck
00:55 Gargantuasauce i should never be taken seriously
00:55 theBear it's attached to my spine, it's like a short rib instead of just a stub like you sposed to have everywhere below your real ribs, been pressing on the inside of my hip bone for a lifetime, formed a nice little divet like a arm socket or something
00:55 theBear how you know if he sounds like donald duck ?
00:57 GuShH what kind of clown ass place is this guy from? https://www.youtube.com/watch?v=nlvwjc6KAwI
00:57 GuShH look at the plates.... and one up front too
00:57 GuShH wtf
00:57 GuShH might as well have the plate bolted to your helmet ffs
00:57 GuShH that's ridiculous
00:58 theBear wtf ? video cam says a dude is messing with the whatsit, phone box outside, got a safety vest on, but it's sunday afternoon ?
00:58 rue_house theBear, I'd do surgery for ya, even tho its really messy
00:58 rue_house and you know what because I have no idea what I'd be doing, Id be really carefull
00:58 rue_house and neat
00:58 theBear heh, i've done surgery on myself before, just there's nothing to be done
00:58 theBear hehe
00:58 rue_house if you dont know what your doing, do it neatly.
00:59 theBear should i go abuse him ?
00:59 GuShH yeh yeh
00:59 theBear whaddya call it, network interface box or something
00:59 theBear damned pills
00:59 GuShH shove a fluke up his ear
00:59 rue_house who you gonna abuse?
01:00 theBear gaar ow ! there's a telco van out the front, i spose he's legit
01:00 theBear if i drop out tho, check the papers tomorrow for cripple kills telco tech and found lying on the ground crying next to his body
01:00 GuShH LOL
01:00 rue_house does the extra rib cause much problems?
01:01 rue_house I need to build some proper medical imaging quip
01:01 theBear rue_house, it meant i was always bound to have serious problems, without it i coulda taken the various injuries and hard work over the years and probly wouldn't have got like this till i was maybe 60
01:02 rue_house http://www.ebay.com/itm/20pcs-MC-38-Wired-Door-Window-Sensor-Magnetic-Switch-Home-Alarm-System-/150897661260
01:02 rue_house think thats an ok deal?
01:02 GuShH who knows
01:03 theBear less than a dollar each ? it's an outrage ! how dare they charge that much ! and including screws for that price !!?!??! it's gotta be a scam
01:04 rue_house can you feel anything when your out cold drunk?
01:04 theBear yep, also i don't get that drunk, too much practice, but very drunk with pills that should stop me breathing or heartbeating and it don't help
01:04 rue_house it could be your tiket man, imagine how much a genuine human rib could go for ont eh black market
01:04 theBear i got muscle relaxers that even slur my words
01:05 theBear it's only a stub, not much distance from spine to hip bone inside
01:05 rue_house meh
01:05 rue_house just sayin
01:05 theBear they call it a transverse process or sumthin
01:05 rue_house maybe with some help someone could turn it into a girlfriend for ya
01:06 rue_house (religious joke)
01:06 theBear i aint that desperate yet
01:06 theBear yeah i know
01:06 theBear apples and snakes and shit
01:06 theBear being non-christian i know the bible well :)
01:06 rue_house :)
01:06 theBear several versions of it
01:09 GuShH specially the "shit" part
01:09 theBear heh yeah, there's several pages about that
01:09 rue_house yea so eve had all sons, and they had their kids with... who?
01:09 Jak_o_Shadows The fairies, woold-elves and such. Didn't you read your CS Lewis?
01:10 rue_house :) nope
01:10 theBear nope
01:10 rue_house ok there are so many things I'm not gonna say
01:10 rue_house anyhow
01:11 theBear hehe
01:11 theBear i on the other hand say anything that pops ionto my head
01:11 rue_house shall I buy 6 vacuum cleaner motors to do quality checks for running my truck or should I get the other stuff in first
01:12 rue_house http://www.ebay.com/itm/Adjustable-Infrared-proximity-switch-photoelectric-detect-sensor-/280962790378
01:12 rue_house hmmm
01:12 rue_house I think thats an ok price
01:13 rue_house its the mowerbot, it would be an upgrade, upgrade budgets are $20
01:13 rue_house http://www.ebay.com/itm/300V-100A-Volt-Amp-Digit-AC-Dual-Display-LED-Panel-Meter-w-Current-Transformer-/281124367768
01:13 rue_house and then there is stuff like that that I dont need at all, but I really want
01:17 theBear aww why can't i find my chauffeur ? it's 2pm, if i start shuffling now i might get to the corner shop by sundown, if i'm lucky
01:29 rue_house http://www.ebay.ca/itm/390614051461
01:29 rue_house i like the way there are still machine chips in the teeth
01:29 Jak_o_Shadows At not quite it's full distance, the arm can carry about 160g
01:30 rue_house whew, I thought you said 160kg for a sec
01:30 rue_house I was worried you beat ours
01:31 Jak_o_Shadows haha, not with hobby servos
01:32 rue_house you could with some kinda assist
01:33 rue_house ok version 1 of supper I burnt, to a crips
01:33 rue_house version two has too much salt and too much pepper
01:34 Jak_o_Shadows What does your arm do?
01:34 rue_house the robotics kid made it
01:34 rue_house I directed
01:34 rue_house its 5 axis
01:35 rue_house two of which are gripper
01:35 rue_house uses 400kg linear actuators
01:35 Jak_o_Shadows nice
01:36 theBear my arm smokes and feeds me drinks
01:36 rue_house http://eds.dyndns.org/~ircjunk/robots/arm5/p1030984.jpg
01:36 rue_house theBear, has me beat
01:37 theBear what the crap ? that's yours ?
01:37 rue_house yea
01:37 rue_house the robotics kid made it
01:37 rue_house now its just taking up space
01:38 theBear that's heavy duty ! you should make it go all hal like robert downey juniors arm
01:38 rue_house slow as all hell
01:38 rue_house http://eds.dyndns.org/~ircjunk/robots/arm5/p1030087.jpg 400kg grip means its great at crushing cans
01:38 theBear well, shove a rocket up it's arse
01:39 theBear heh, less impressive looking up close
01:39 Jak_o_Shadows automate your casting stuff
01:39 theBear oh, all the fancy looking bits are the actuators
01:39 theBear not the bits he built :)
01:39 rue_house http://eds.dyndns.org/~ircjunk/robots/arm5/
01:40 theBear whats a Phusion passenger ?
01:40 rue_house dunno
01:40 theBear lol, your webserver seems to have one
01:40 rue_house huh
01:40 theBear read the status line under the file listing
01:40 rue_house thats the server furrywolf gave me space on
01:41 theBear how can wolf have a server but no connection ?
01:41 Jak_o_Shadows Just added a 30g counterweight on the arm that moves the most
01:41 MrCurious rue; do you use tobacco?
01:41 rue_house its at a farm
01:41 MrCurious caffine?
01:41 theBear lol, 'use tobacco' ? like, to bribe persons like me ?
01:42 MrCurious he is .... prolific
01:42 rue_house I dont smoke or do alcohol
01:42 eBear IS prol
01:42 MrCurious hmmm
01:42 theBear heh, don't do alcahol, stay in school, heerh
01:42 rue_house hate beer
01:43 rue_house apparently wine too
01:43 theBear rue just gets high on robot building
01:43 theBear apparently wine ? what, someone told you and you believed them ? :)
01:43 rue_house yup
01:43 rue_house no I tried some
01:43 rue_house for a toast
01:44 rue_house bleck
01:44 theBear silly ! butter goes with toast ! wine goes with cheese and stuff
01:44 MrCurious rue, you strike me as talented, but not directed
01:45 MrCurious a little bit of planning... make the robots that build the robots
01:45 MrCurious then control evolution from teh keyboard
01:45 MrCurious dont be so hands on
01:45 Jak_o_Shadows Yeah, maxes out the base one though
01:45 rue_house yea
01:45 rue_house boostrap it, I know
01:46 rue_house I'm using a sideways path
01:46 rue_house I'm teaching kids how to do robotics
01:46 MrCurious that arm is going to scare the *** out of every woman who sees it
01:46 rue_house with special projects ;)
01:47 rue_house more arms, hmmm more arms
01:47 Jak_o_Shadows do some legs
01:47 rue_house http://eds.dyndns.org/~ircjunk/robots/arm6/p1040198.jpg
01:47 theBear heh, not much chance of that
01:47 Jak_o_Shadows Just saying
01:47 theBear women never see my bits and pieces
01:47 theBear err, that came out wrong
01:47 MrCurious have you tried candy?
01:47 rue_house that one needs more pics
01:47 MrCurious booze
01:47 MrCurious subterfuge?
01:48 rue_house bah, I dont think I can eat the rest of this
01:48 rue_house I can take the high salt, but the high pepper is just burning me
01:48 MrCurious thats what she said?
01:49 rue_house my monitor stand it overflowing with $1 items...
01:49 theBear heh, you're learning, not bad
01:49 MrCurious so the eds pics...
01:49 rue_house Electronic Device Services
01:49 MrCurious i take it that is a motor driving a linear expansion joint?
01:49 theBear i wonder if i can work the bike today
01:50 MrCurious like for a satelite possitioning system?
01:50 theBear i really gonna need liquor and smoke soon
01:50 rue_house if you ever name a company, SHORT is as important as descriptive
01:50 MrCurious or just use 2 names
01:50 rue_house MrCurious, yes, its a acme screw
01:50 MrCurious 1 abbrev, and one long form
01:50 MrCurious not seeing how you get the angular movement...
01:51 rue_house heh, its a gearbox that goes to a gearbox that goes to a bike sprocket set that turns the arm
01:51 MrCurious but the elbows
01:51 MrCurious how do they ... elbow
01:51 rue_house its desgned from an excavator
01:52 MrCurious i really think you need to think bigger
01:52 MrCurious your ready
01:52 MrCurious 8' tall biped
01:52 rue_house http://image.made-in-china.com/2f0j00jBaQczsJZvpL/2-8-Ton-CE-Approved-Excavator-ZY28.jpg
01:52 rue_house the mecha is going to be 12'
01:53 MrCurious is it me, or is that the phone booth of ultimate destruction?
01:53 rue_house this summer I need to finish the ring benders
01:53 rue_house so thats the design basics for that arm
01:53 rue_house verry not counterbalanced
01:54 MrCurious oh!
01:54 MrCurious i see linear motion turned to angular
01:54 MrCurious the projecting motor/gear boxes threw me
01:54 rue_house oh, IN the actuator?
01:55 rue_house its a worm drive to the acme screw
01:55 rue_house I tore apart a broken one
01:55 rue_house hmm most of it is the base drive of the new arm
01:56 rue_house which I'v not posted pics of
01:56 MrCurious how many years til this is off teh shelf shit... http://www.scholarpedia.org/w/images/3/3c/Lwr_hand.gif
01:56 rue_house never
01:56 MrCurious if we had access to angular joints like that... nightmares could come alive...
01:57 MrCurious then teh recipee to make it needs to be freed
01:59 rue_house no I'm looking for images of the new arm
02:05 rue_house http://eds.dyndns.org/~ircjunk/robots/arm6/p1050022.jpg
02:06 rue_house the base motor of that is similar to the linear actuators internals, but instead of a shack with a synchropulley, its an acme screw
02:09 GuShH -3°C
02:10 GuShH well it's 5°C on downtown, but I'm on the countryside...
02:10 rue_house heh under 0 congrads
02:10 GuShH there are no real weather stations I can gather data from that are actually within a few miles from here
02:10 MrCurious rue_house: you in argentina too?
02:10 rue_house no canada, its 22c here
02:10 GuShH MrCurious: I wish
02:10 GuShH Then I'd be able to have robot wars
02:11 GuShH Should be cold in Australia
02:11 theBear it is :(
02:11 GuShH How cold?
02:11 Jak_o_Shadows http://thefuckingweather.com/?where=Buenos+Aires&unit=c
02:11 Jak_o_Shadows I don't know what it's talking about
02:11 theBear i dunno, 16c now, but it's 3pm
02:11 GuShH Aside from having such a huge time difference, we share a similar weather
02:11 theBear had at least one 0c last week
02:11 Jak_o_Shadows In what bloody country is 5C alright?
02:11 theBear doesn't get much colder than that
02:12 GuShH lol fucking weather
02:12 GuShH OK but that data is gathered in downtown
02:12 GuShH Where it's warmer
02:12 GuShH Crap, I used to live near downtown but not that close, and during summer it was horrible.
02:13 GuShH So hot at night.
02:13 GuShH a more local-ish weather report but in spanish http://www.meteored.com.ar/tiempo-en_Belen+de+Escobar-America+Sur-Argentina-Provincia+de+Buenos+Aires--1-16625.html
02:13 theBear scorchio
02:14 GuShH wat
02:14 GuShH They promised snow... but no snow.
02:14 GuShH and it's getting warmer by now
02:15 MrCurious nice
02:15 GuShH of course down south... it is snowy http://www.meteored.com.ar/tiempo-en_San+Carlos+de+Bariloche-America+Sur-Argentina-Rio+Negro-SAZS-1-16916.html
02:15 GuShH that's where a friend lives, wish I could sell everything and move over there, you get a proper snowy winter every year
02:16 MrCurious your site doesnt do san diego.
02:16 MrCurious apparentlt brazil has a lot of san diegos
02:16 MrCurious he must have "got around"
02:16 GuShH o.O
02:16 GuShH lol
02:16 GuShH So he wasn't much of a saint
02:17 MrCurious http://thefuckingweather.com/?where=san+diego+california
02:17 MrCurious weeee bit warm
02:17 GuShH &unit=c
02:17 GuShH when will you guys upgrade
02:17 Jak_o_Shadows and, 17C is cold
02:17 GuShH 17-22 is ok
02:18 MrCurious we cant help ourselves... (Republicans...
02:18 GuShH high 28 is too high.
02:18 rue_house so for ~$7
02:18 rue_house http://www.ebay.com/itm/L298N-DC-Stepper-Motor-Driver-Controller-Module-5V-for-MCU-arduino-robot-Car-/170929162897
02:18 rue_house you can get that, or
02:18 GuShH 25 is the perfect temperature
02:18 rue_house http://www.ebay.com/itm/RC-Scale-Model-Plane-Turborix-25A-Brushed-Motor-ESC-Electronic-Speed-Controller-/150965481742
02:18 rue_house that
02:18 GuShH in celsius.
02:18 rue_house not much of a competition eh?
02:19 GuShH bah I can't sleep again
02:19 rue_house I'm avoiding it with tea
02:19 Jak_o_Shadows What do you call a gun mount that lets the gun fire?
02:19 GuShH ?
02:19 GuShH for calibration?
02:19 Jak_o_Shadows Well, for a nerf sentry gun.
02:20 GuShH I don't do nerf
02:20 Jak_o_Shadows I can't figure out how i'm going to hold the gun.
02:20 GuShH nor nerds
02:20 ShH grins at the
02:20 GuShH which gun
02:20 rue_house aha ESC = Electronic Speed Controller
02:21 Jak_o_Shadows Um, preferably most of the smaller ones. Maverick, Recon, Barricade. http://images2.wikia.nocookie.net/__cb20130331002813/nerf/images/c/c2/Mk%2C.jpg
02:22 rue_house so 10A is about $10
02:22 GuShH so look up calibration gun mount sight calibration etc
02:22 rue_house for $1 you get 20A
02:22 GuShH steady
02:22 GuShH rest
02:22 GuShH etc
02:23 Jak_o_Shadows rue_house: the arduino one should be about $2 I would have thought.
02:23 rue_house http://www.ebay.com/itm/HiForce-240A-Car-1-10-ESC-65A-Brush-Motor-Speed-Controller-1-10-/300897498247
02:23 MrCurious you wanting to drive a stepper?
02:23 rue_house I thik I'll just scrape SMT fets off motherboards
02:23 MrCurious you want something like this
02:23 MrCurious http://www.ebay.com/itm/261210377837?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
02:23 rue_house no, I need to make dc mtoor drivers
02:23 MrCurious step and dir
02:23 MrCurious oh
02:24 rue_house I can make them for less than $13 ea
02:24 rue_house so I will!
02:24 GuShH ahh stupid gif drawing
02:26 rue_house ?pt=Radio_Control_Parts_Accessories&hash=item232bf6010a
02:26 MrCurious they are nice drivers... the heat sink is overkill
02:26 rue_house what part of that can take 110A?
02:26 rue_house and ... whats...that....cap.... hanging.... out..........
02:26 ShH shi
02:27 rue_house ... 110A goes where?
02:27 rue_house maybe from one side to the other of the heatsink if you attach the right clips?
02:27 MrCurious its not a 110 A
02:27 MrCurious sorry
02:27 Jak_o_Shadows Peak rating?
02:28 MrCurious 3.4A
02:28 rue_house but it says right there!
02:28 rue_house aha, at the $18.50 level we find 500W scooter motor controllers
02:29 rue_house http://www.ebay.com/itm/1-10-RC-Racing-On-Road-Car-340A-Programmable-Brushed-Motor-ESC-Speed-Controller-/380558123090
02:29 rue_house china must use small amps
02:29 Jak_o_Shadows haha
02:30 rue_house ah, I bet,
02:30 rue_house thats the datasheet current rating
02:30 rue_house it has a little star beside it
02:31 rue_house saying that if the package could take that much current, then that would be the chip limit
02:31 ShH would like to warm up his testicles by MrCurious'
02:31 rue_house but that the package can only take 40A
02:32 rue_house aha, ok
02:32 rue_house I'm gonna go convert the ups pile... no...
02:33 rue_house that wont work
02:33 rue_house motherboards it is
02:33 GuShH ????
02:33 rue_house motherboard fets are 32V
02:33 rue_house usually about 20A
02:33 rue_house by package limit
02:34 rue_house so I'll go look at making some motor drivers
02:35 MrCurious hAH! AC on...
02:36 ShH idly freezes his testicles on MrCurious
02:36 MrCurious bah! i am poor. window AC.
02:36 GuShH Wait, it's 17°C and you've got the AC on?
02:36 MrCurious no central air here
02:36 GuShH why even turn it on
02:36 GuShH I plain don't have any AC in this house at this point. We had central on the previous one
02:37 GuShH That thing was a monster.
02:37 MrCurious only reason today is humidity
02:37 GuShH Oh at the apartment I rented for a couple months they had a window unit
02:37 GuShH well, two.. one butchered, the other kinda worked so I had to fix it to get past the summer
02:37 GuShH stupid assholes.
02:37 MrCurious AC prevents arguments
02:37 GuShH the butchered one was missing a couple relays, the entire wiring was taken apart...
02:38 GuShH kinda figured they turned down the quote and the "technician" just pulled all the wires and relays out
02:38 GuShH I mean, why else would it be in that state?
02:38 GuShH Meh, doesn't matter.
02:38 GuShH ACs are huge power hogs...
02:38 MrCurious unless dad was a ... tinkerer
02:39 GuShH I don't know the owners that well
02:39 MrCurious they always include extra parts.. so you can make your own projects
02:39 GuShH lol
02:39 GuShH I actually maxed out the compressor on the other unit, tripped it's thermal protection a couple times
02:39 GuShH it was a HOT summer.
02:40 MrCurious clearer thinking mind makes a cellar
02:40 MrCurious except in California. where there are constant quakes
02:40 GuShH Never liked apartments...
02:41 GuShH In fact, during my stay.. they robbed an apartment on the next floor, or the floor under...
02:41 GuShH Complete with angle grinder and a sledge hammer.
02:42 rue_house wow
02:42 GuShH I was just waiting by the door with 6 good friends, wasn't a good night.
02:42 rue_house nobody noticed?
02:42 GuShH and those were leaded friends.
02:42 GuShH I called 911, saw the lights outside when they came, but I doubt they ever got into the building
02:42 rue_house you didn't let them in?
02:42 GuShH The guy in charge of the building said "the owner of the flat lost his keys so he called a locksmith to get in" (bullshit)
02:43 GuShH rue_house: they didn't ring
02:43 GuShH Anyway, it felt like they were going door to door, but it was just one door they took down.
02:43 rue_house http://www.ebay.com/itm/1-CNC-Single-One-Axis-TB6560-3-5A-2-Phase-Stepper-Motor-Driver-Board-Controller/161070823477
02:43 GuShH Shitty experience and it just confirmed how crappy apartments can be, security wise
02:44 rue_house oo
02:44 GuShH Plus one staircase, two elevators... hardly a way out if they block the entrance
02:44 GuShH but 10 shipping!
02:44 GuShH and it's not buy now
02:45 GuShH they go for 15 with shipping
02:45 rue_house huh
02:45 rue_house wonder if there is anything in that box
02:45 GuShH yeah a tiny pcb
02:45 GuShH robotustra (?) has a 3 axis version
02:46 GuShH or 4... maybe 3
02:46 GuShH he's happy with it
02:46 MrCurious looks fancy
02:46 rue_house to the shop!
02:46 GuShH nananana rueeee
02:47 GuShH solder! paw! --- resistors! pew! --- capacitors! kablam!
02:49 rue_shop2 hmm youtube on how to flare a pipe
02:49 GuShH this guy seems to use a lot of cast iron stock... hmm
02:50 GuShH is cast iron readily available in blocks, cylinders, etc? how does it compare price-wise to alu?
02:50 GuShH or regular carbon steel
02:52 MrCurious that style of stepper driver messed with me for a bit.. all the step, dir, en - need a ground
02:52 ShH pats MrCur
02:53 MrCurious was surprised 3+ seperate grounds were needed and not 1
02:53 MrCurious like it was made in brazil and they didnt finish doing the math
03:08 MrCurious g'night all
03:12 rue_shop2 aha, this data collecting for measuring battery capacity is the perfect excuse to work on my digital scope
03:22 R0b0t1 MrCurious, I've seen that
03:22 R0b0t1 I think the signal and ground form a loop
03:22 R0b0t1 to help resist oise
03:22 R0b0t1 noise
03:22 rue_shop2 hmm I din't write out my protocol in the client program
03:24 rue_shop2 oh yea, the hardware tells the pc what the sample rate and scales are
03:24 rue_shop2 maybe I'll just hack this for now
03:26 rue_shop2 the overcharge protextion on that battery didn't seem to work, I wonder if the undercharge works
03:26 rue_shop2 they came charged to 4.2V
03:26 rue_shop2 is 3.7 just the nominal for li-ion?
03:27 theBear i think 3.7 is on the low end of a charge, even tho they rated at that
03:27 rue_shop2 hmm
03:27 theBear right now i got 23% for 3734mV on the fone
03:28 theBear fairly new battery, but i think % is purely voltage related
03:28 rue_shop2 I made a current regulated load bank
03:28 rue_shop2 I'm gonna run a constant current test
03:28 rue_shop2 ah I can do this with my generic io baord
03:29 rue_shop2 !? last babyboard!?
03:35 rue_shop2 can anyone think clearly enough to work out the equiv amp-hour value of a 160000uF capacitor with a start voltage of 4V and a finish voltage of 3.2V?
04:17 theBear no
04:17 theBear you could ask me my own name right now and i might get it wrong
04:17 theBear and i just started drinking for the day, after dosing up to get to the bottleshop
04:18 theBear hehe, they like me up there.... put a box in my backpack so i knew it would fit and just got them to jam the bottles in there for me... i can't reach the bottom shelf
04:38 Jak_o_Shadows ha. Arm has no jitter, so went to turn it on, and I turned it off
04:44 theBear you foolish fool !
05:17 rue_shop2 .3V at 4A
05:18 rue_shop2 battery has .075 ohms plate
05:18 rue_shop2 esr, whatever
05:18 rue_shop2 now that I breadboarded, tested, and made a pcb, I want to change how this works
05:24 rue_shop2 hmm, in the meantime, this can do 1C
05:24 rue_shop2 oh wait
05:25 rue_shop2 I cant test a 4V 4Ah battery to 4A with a 1R current sample resistor
05:25 rue_shop2 *sigh*
05:28 rue_shop2 .01R 1W is 10A
05:28 rue_shop2 10A is 1V @sample
05:28 rue_shop2 no, its .1V
05:29 rue_shop2 drat I just finished soldering the pcb too
05:31 rue_shop2 .05R
05:31 rue_shop2 thats 5W atleast
05:32 rue_shop2 still 10A
05:32 rue_shop2 ok
05:32 rue_shop2 .5V at 10A
05:32 rue_shop2 I can test a 4V battery just fine with that
05:54 rue_shop2 pfffffffffff 3:30am and I'm falling asleep
13:16 MrCurious well, news isnt all about zimmerman and race this morning, but its been replaced by even more disturbing news abour serial killers
13:40 e_shop2 works on, "electronic compensation for backdrivable platform dri
13:40 MrCurious royal baby, private hospital wing, dedicated staff... sucks to be... common
13:42 MrCurious oh! rue is canadian. he must be going potty for the new royal birth! canadians are still subjects of the queen :)
14:13 rue_shop2 no
14:14 rue_shop2 nobody is even talking about it
14:14 MrCurious love the latest bipedal 4 armed mech on falling skies
14:14 MrCurious terrifying
14:17 Guest14246 Canada is greatly saddened by this news.
14:17 Guest14246 The queen, not the four armed mech.
14:17 Guest14246 Canada approves of four armed mexhs
14:32 MrCurious ROFL
14:32 ace4016 what happened to the queen or some baby?
14:33 MrCurious the pre-queen, bride of the prince is having a baby. the queen wishes it to happen sooner than later, so her vacation plans to scotland are not delayed
14:34 ace4016 lol....wow
14:35 ace4016 so is she inducing labour?
14:39 MrCurious unknown
14:39 MrCurious may just tuck into a spicy curry the news speculates
14:48 MrCurious WOW. pope rolling through brazil, and not using the bullet proof pope mobile
14:48 MrCurious now thats an act of faith
15:27 SquirrelCZECH hi folks!
15:28 SquirrelCZECH is there someone who knows weight of carbon tube 6/5mm ?:-)
16:44 MrCurious wouldnt that depend on density and exact measurement
16:49 robotustra SquirrelCZECH: I have 4mm diameter carbon tube
16:50 MrCurious 21.6C(71F) and humid, but i dont think i am complaining
16:50 Curious converted to metrick for the 3rd world friend
16:51 MrCurious did i just spell metric with a k, demonstrating the value of a first world education...
16:55 robotustra SquirrelCZECH: I think there is a easy way to calculate weight
16:56 robotustra m = volume * density
16:57 robotustra density of carbon fiber is about 1500 kg/m^3
16:57 robotustra 1.5 g/cm^3
16:57 robotustra I hope you know how to calculate volume
16:58 robotustra if OD = 6 mm, ID = 5 mm
16:59 robotustra then crossection is = (OD^2 - ID^2)*3.1415926
17:01 MrCurious awww, you made SquirrelCZECH too shy to respond...
17:01 robotustra :)
17:01 robotustra let's make it rouphly
17:02 robotustra (36-25) *3.14 is about 34 mm^2
17:02 robotustra multiply by 1000 mm = 1 m it's 34000 mm^3
17:03 robotustra it's 34 cm^3
17:03 robotustra 1.5 * 34 = 51 gramm
17:04 robotustra the weight of 1 meter carbon fiber tube with 6 mm outer diameter and 5 mm inner diameter is about 50 gramms
17:07 MrCurious is that kind of tube expensive?
17:07 MrCurious is it flexible, or super ridgid?
17:09 MrCurious oh! pro-zimmerman group marching towards a pro-trevon martin group
17:09 MrCurious in texas
17:09 MrCurious i think this is what gladiator games have degenerated into...
17:16 MrCurious oddly, its not hard to guess which rally is which
17:19 robotustra oh, GB is online
18:07 MrCurious omg yemmen is messed up
18:07 MrCurious why does our news not share these details
18:08 MrCurious 10 minutes of BBC news (UK version) and i know more about the outside world than 3 days of CNN give
18:10 robotustra MrCurious why are you watching zombobox?
18:11 robotustra all important news came to me from my friends
18:11 robotustra I have even to watch zombo-box
18:11 MrCurious XBMC
18:12 MrCurious was learning about the situation for migrants in yemen
18:12 MrCurious they head to saudi, but get captured and tortured in yemen
18:12 MrCurious held hostage in insane numbers, until their parrents pay several randsoms
18:12 MrCurious then they are lamed, blinded, raped before they can be freed
18:30 MrCurious as distasteful as FOX news is, I am watching it for a while to see if it shows me better news
18:36 Gargantuasauce_ bbc is better but still pulls the wool over your eyes about some stuff
18:37 Gargantuasauce_ just go on an aggregator site like google news
18:37 MrCurious couldnt stomach faux news... switched to sky news live
18:37 MrCurious that doesnt work any more...
18:37 MrCurious i have taught google i am a raging liberal, and now it only shows me stories that make me angry :D
18:38 Gargantuasauce_ hehe
18:48 robotustra journalists should be killed after politics
18:49 MrCurious wow. brits have to ASK to get porn on their internet
18:50 robotustra the nexst step will be paying for that porn
19:12 MrCurious quad stepper driver HALF wired to AVR
19:29 MrCurious and soldering done. nothing left but to see how bad i goofed up
19:46 MrCurious motors and power wired, now to update code to support 4 motors with new pins
20:05 MrCurious 4 steppers up and working as desired :D
20:09 rue_shop2 "and on page 3 you say the mowerbot may have been given too much pulling strength, could you expalin that?" "One of the technicians monitoring it heard it working with what sounded like a prolonged period of drive motor force, when he checked it had caught itself on a 200lb picknic table and was dragging it across the lawn"
20:10 rue_shop2 ok it wasn't a picknic table it was a 40x50' tarp, but it was a halarious sight
20:22 GuShH rue_shop2: do you know the brand SPI (micrometers)
20:22 MrCurious ok, now this is working bettter
20:31 MrCurious why expose a SLEEP and a ENABLE and a RESET, but not expose current delay on a stopped motor...
20:41 rue_shop2 I thought all micrometers were made y china
20:41 GuShH http://articulo.mercadolibre.com.ar/MLA-468333128-micrometro-spi-_JM
20:53 Tom_itx no
21:00 GuShH http://www.swissprec.com/cgi/issrhm
21:01 GuShH seems similar in quality to etalon - tesa stuff
21:07 MrCurious GuShH: you going to see the pope? he is hnear
21:13 MrCurious GuShH: i got one of those from harbor freight for like $10
21:13 robotustra pope is not interesting
21:14 robotustra pope is a human
21:43 GuShH MrCurious: why would I
21:43 GuShH MrCurious: hm? why would harbor freight sell SPI products
21:43 GuShH did you see the paypal fuck up
21:44 GuShH on the 19th
21:44 GuShH 92 billion dollars
21:44 GuShH "a system error"
21:45 GuShH I keep saying PayPal is written by hindus.
21:46 GuShH robotustra: I'd rather spend the money on tools than head over to brazil to see the pope
21:46 GuShH ...
21:46 GuShH actually I'd rather spend the money on booze and hos.
21:47 ShH wonders if Booze&Hos ex
21:47 GuShH Like D&C for theBear inside you.
21:47 GuShH err D&G
21:49 robotustra https://www.tindie.com/products/jkicklighter/adns-9800-optical-laser-sensor/
21:51 robotustra ordered 2
21:51 robotustra for eyes
21:51 GuShH pfft
21:53 robotustra translate
21:54 Jak_o_Shadows Arn't they only good for a couple of inches?
21:56 robotustra I want to use them for positioning of eyes
21:56 robotustra they will work on a distance of 1-2 mm
21:57 robotustra I think 1 mm only
22:11 GuShH robotustra: are you making a dalek?
22:12 robotustra no
22:12 GuShH I can lend you a used plunger
22:12 GuShH theBear can hand you a ringmodulator
22:12 robotustra I'm thinking right now how to mill this part tomorrow http://oi42.tinypic.com/34o4hea.jpg
22:12 GuShH lots of wasted material
22:13 robotustra it's small
22:13 GuShH can't be designed in another way?
22:13 robotustra 28 mm x 28
22:13 robotustra no, I cant
22:13 GuShH a plate and separate standoffs
22:13 GuShH then you have a fundamental error.
22:14 robotustra the top suface hide alan bolts' heads
22:14 robotustra and space under is for chip
22:14 GuShH you are on a whim that's why you can't see any other way around it
22:14 robotustra plate itself is a heatsink
22:15 robotustra I already somplified this part
22:16 robotustra I need the bolts as short as possible, and hide them
22:16 GuShH recessed
22:16 robotustra otherwise they can hit some other parts of eye during motion
22:16 GuShH or use grub screws
22:17 robotustra it's 2mm bolts
22:17 robotustra M2
22:17 GuShH so
22:17 GuShH You love to complicate things.
22:17 robotustra me? and what about you?
22:17 GuShH it could be as easy as a rectangular piece of aluminum with two spring steel clips
22:17 GuShH BUT NO
22:17 robotustra :)
22:18 robotustra I think about your proposal
22:18 GuShH I need coffee and maybe a snack.
22:19 robotustra the only thing why I'm going to do this is that I'll have 1 part instead of 4 bushings and 1 plate
22:19 robotustra 1 against 5
22:20 robotustra and I have to mill the same amount of aluminium to get 1 mm thick Al plate
22:32 GuShH ok
22:35 GuShH damn it, cracked window....
22:35 GuShH temperature contrast I guess
22:36 GuShH that's how cold it was today outside
22:36 GuShH possibly stressed, but I don't think so
23:04 MrCurious i have no idea how i lived prior to discovering HOT GLUE
23:04 MrCurious it lets you have clean do-overs!
23:06 robotustra but it's not strong enough
23:06 MrCurious hot glue is hot and sticky, and now i am awash in spider webs
23:07 MrCurious not for structural... to insulate solder joints, and ease stress on solder joints
23:07 MrCurious and glue pcb together
23:07 MrCurious pleanty strong for that
23:07 robotustra and how to disassemble it?
23:08 MrCurious dissassemble!!!!!!
23:08 robotustra hot glue reminds me about chinise toys
23:08 MrCurious johney-5 is alive!
23:08 robotustra yeah
23:08 MrCurious there is no disassemble
23:08 MrCurious bobot joins hall of fame when next is born
23:08 robotustra My requiements to all my stuf to be easily disassembleable
23:09 robotustra is to be
23:09 MrCurious only to a certain level...
23:09 MrCurious i am content leaving teh arm cpu on teh cpu board
23:20 MrCurious and robot base has rotated to random rotations on my desk, tethered to a pc and a bench supply
23:28 MrCurious and omni wheels in a quad arangement have a WEE flaw...
23:28 MrCurious they are NOT a tripod
