01:19 Curious y
01:24 MrCurious do you people ever shutup?
01:24 MrCurious cant get a word in edge wise
01:24 evil_dan2wik what?
01:24 Faeks Non
01:25 MrCurious anyone here working with usb v4l2 video cameras?
01:25 evil_dan2wik I'm not.
01:26 MrCurious evil_dan2wik: what is your project?
01:26 evil_dan2wik My current project: Upgrading to windows 8.1
01:27 evil_dan2wik I have had 3 roll backs so far.
01:27 MrCurious i upgraded my laptop from 8 to 8.1
01:27 MrCurious wished i didnt
01:27 MrCurious 8.1 perks sucked
01:27 MrCurious gaving a message on my desktop about secure boot being not properly set up... annoying
01:28 MrCurious have a strategy to revert the upgrade when you hate it
01:29 evil_dan2wik MrCurious, So I should stop tring?
01:30 MrCurious thats just my opinion
01:30 MrCurious your needs may be different
01:30 evil_dan2wik I'm fine to stay here, Its just I want to be up to date.
05:46 GuShH evil_dan2wik: the chinese have reached your washing machine!
05:46 GuShH SECURITY BREACH!
05:51 evil_dan2wik GuShH, It wasn't the relay, It was the water pump.
05:51 evil_dan2wik Which then blew the relay
05:52 evil_dan2wik The motor was supplied by china and the machine was constructed in spain
05:58 GuShH evil_dan2wik: might as well be all chinese
05:59 GuShH the pump is the second most important part of the machine
05:59 evil_dan2wik no.
05:59 GuShH yes.
05:59 evil_dan2wik no.
05:59 GuShH I said yes.
05:59 evil_dan2wik Logic board > Main drive motor > Pump
05:59 GuShH not really
05:59 GuShH there's no need for a logic board, originally all you had was a motor a couple pulleys and a belt, boy.
06:00 evil_dan2wik But without the logic board, the machine isn't smart.
06:00 GuShH it's not smart anyway
06:00 GuShH even with fuzzy logic
06:00 GuShH it's a dumb ass drum with a motor.
06:00 GuShH and a pressure switch underneath
06:01 GuShH functionality wise it's main components are the drive motor and the pump!
06:01 GuShH the rest is bullshit and plastics.
06:02 GuShH I've got an issue with my "smart" washing machine, the water inlet keeps clogging up
06:02 GuShH and it's so" smart" it doesn't know whether there's water pressure or not, whether there's any water at all in fact.
06:02 Faek But is that an issue with the "smarts" ?
06:02 GuShH it will keep trying to fill until it times out after an hour and shows an error code
06:03 GuShH Faek: just in general, they're not smart whatsoever, that's the point...
06:03 evil_dan2wik Mine is smart, It eats socks.
06:03 GuShH they give you silly music, sound effects, nice touch panel and other bullshit that have nothing to do with it's main purpose
06:04 GuShH cleaning wise they are worse and worse as time goes by, less power and less water is used to be "green" (cut costs)
06:04 evil_dan2wik Mine has a knob and a button.
06:04 evil_dan2wik The button is a click click switch.
06:04 GuShH less water means the drum doesn't have to withstand much force, that means a smaller motor as well and everything is downsized
06:04 evil_dan2wik The knob is a click click knob too.
06:04 GuShH mine has a display and more buttons than a keyboard
06:05 GuShH they're all the same apart from the user interface anyway
06:05 GuShH I should fix my old Sanyo, that thing was great.
06:05 GuShH you could fill up the drum with towels and it wouldn't mind, if I place 2 towels on the new machine it stalls with an error code
06:05 GuShH on/in
06:05 evil_dan2wik Push this button to enable hot water while playing a chime. Push this button to enable hot water while playing a ding.
06:06 GuShH I hate all consumer products
06:07 GuShH If I had the space I would source an industrial washing machine
06:07 evil_dan2wik Make your own..
06:07 GuShH all stainless steel, no nonsense.
06:07 evil_dan2wik I almost convinced my mom to buy the washing machine with the arduino sticker.
06:07 GuShH what
06:07 ShH stares at evil_dan
06:07 evil_dan2wik There are washing machines with arduino brains.
06:07 GuShH wat
06:08 evil_dan2wik I openned it up and there was a whole UNO in there.
06:08 GuShH bullshit
06:08 evil_dan2wik It had the SMD chip and the rails taken off and soldered directly.
06:08 GuShH if that's real I will make it my duty to beat up whoever is behind it, but you'll have to pay for the plane.
06:09 evil_dan2wik sorry, the SMD chip was the version.
06:09 GuShH I'm sure theBear would be more than willing to assist
06:10 GuShH A good way to off them would be to force them into the drum, seal it and hook up a hose to a cow's arse, then wait.
06:13 evil_dan2wik I can't seem to find the washing machine on google.
06:14 GuShH evil_dan2wik: killed it already
06:14 GuShH who's next
06:14 evil_dan2wik huh?
06:14 ShH is pretending to be a hitman
06:14 GuShH I think my neighbours are scared of me
06:14 GuShH Or might have the wrong idea.
06:15 evil_dan2wik http://grietinfo.in/projects/MAIN/EEE2013/cd-3-projectdocumentationpdf.pdf
06:15 GuShH no thanks
06:39 theBear does an ass need kicking ?
08:23 GuShH theBear: they've made an arduino based washing machine, it seems
08:23 GuShH I'd say it calls for more than an ass kicking...
08:25 zap0 GuShH, does every app for it insist on wanting full access to your address book?
08:28 GuShH zap0: hm?
08:29 GuShH damn I'm tired... gotta change two tie rods among other things and I just can't be arsed
08:30 zap0 many apps on android want access to all your contacts and address book.. like a fart app will. it's kind of ridiculous.
08:30 GuShH but what's android got to do with arduino
08:30 GuShH or is there also an android washing machine
08:30 GuShH don't tell me
08:30 GuShH I might go medieval on their ass if there is
08:31 GuShH darn it I don't have a tie rod clamp (for the ends) hmmm I wonder if a nut and a rubber mallet will do
08:31 zap0 lol. misread. i read android.
08:31 GuShH there's probably an android one as well.
08:32 GuShH there actually is.... sigh
08:32 zap0 it not be suprised if white-goods aren't already looking for ways to intergrate android though.
08:32 GuShH Samsung made it
08:32 GuShH http://timesofindia.indiatimes.com/tech/itslideshow/18527905.cms first link
08:32 GuShH why the FLYING FUCKING SHIT would anyone want to sync their phone to the washing machine? EVER
08:32 ShH walks
08:33 GuShH http://photos.expertreviews.co.uk/images/front_picture_library_Expert_Reviews/dir_345/er_photo_172843_52.png
08:33 zap0 power usage stats.
08:33 GuShH YES PLEASE WASH THESE SOCKS
08:33 GuShH TAP TAP TAP
08:33 GuShH OH LOOK ITS SPINNING
08:33 zap0 finished cycle notification.
08:33 GuShH I SPENT 10K AND IM AWESOME
08:33 GuShH zap0: that's what the beep is for
08:33 GuShH this is retarded.
08:33 GuShH plus you already know how much time it'll take
08:34 zap0 but i might be in some other part of the house!
08:34 GuShH mine says "15 minutes" so you already know when it'll be done.
08:34 GuShH TIME IS TIME
08:34 zap0 i might even be out
08:34 GuShH then you don't need to know
08:34 GuShH as you won't be removing the clothes
08:34 GuShH this is simply an expensive gimmick for people with nothing else / better to do in life
08:34 zap0 true.
08:34 GuShH it's not the future it's just another layer of complexity making the product less reliable, on purpose.
08:35 GuShH plus you come to tell me the screen and hardware running android consumes less power than a simple mcu and a few buttons with PERHAPS a 7 segment display?
08:35 GuShH there's nothing green about it
08:35 GuShH and on top of the retarded product list, we've got the curvy phones.
08:36 GuShH yey, push on it's edge so it rolls forward allowing you to see the time!
08:36 GuShH WEAR A WRIST WATCH
08:36 zap0 i saw a car advert on the TV yesternight... they spent 80% of the advert talking about how it's got some iTunes store streaming thingy built in, so you can listen to music.. WHAT THE FUCK is going on... a $35,000 car is adverted by the fact it's got a $100 tablet stuck on the dashboard.
08:36 GuShH there are cars named "mp3" and other shit
08:36 GuShH fords
08:36 zap0 FUCK OFF!!!!111
08:36 GuShH I swear.
08:36 zap0 the word has gone mad!
08:37 zap0 world/
08:37 GuShH I've been tempted to kick one a few times
08:38 GuShH http://gomotors.net/photos/d7/1c/vendo-ford-ka-mp3-2007-mar-del-plata_aa8f6.jpg?i
08:38 GuShH It had to be a Ford...
08:38 GuShH That's a slut's car anyway, or better said.. a girlie car, just like the new bettle or the new minis
08:38 zap0 i knew the whole digital world was shit the day they removed the knob from the microwave front panel.
08:38 GuShH or the smart...
08:38 GuShH microwave ovens became highly disposable items after they've turned digital
08:39 GuShH mainly due to the panel membranes wearing out, making them impossible to use
08:39 GuShH prior to that, it was just a switch or two...
08:39 GuShH and it's still the same shit underneath, except now they're using inverters to lessen the cost
08:39 zap0 1 knob. 1 go button. that was ideal. why did they change it?
08:40 GuShH it's still an interrupted stream of microwaves, it's not modulated or anything
08:40 GuShH on - off -on -off
08:40 GuShH we had one for over 30 years, it had 3 buttons and a knob!
08:40 zap0 sanyo?
08:40 GuShH I hear new microwave ovens last a year if you use it every day and you're lucky
08:41 zap0 designed to last warranty+1 day.
08:41 GuShH my previous washing machine was sanyo, I didn't throw it away because it just needs a solenoid and other simple repairs, it's awesome compared to the new stuff.
08:41 GuShH hence I'd rather refurbish it than buy something new again
08:41 GuShH zap0: it was GE
08:41 GuShH general electric stuff used to be great, not sure about now
08:42 GuShH I must admit I enjoy the way new fridges and other appliances look now adays, but I know they won't last long so I don't even bother.
08:43 GuShH better have them hidden in some room and have them do their thing.
08:44 GuShH odd, both tie rods are exactly the same... I thought they came with opposite threads (left and right)
08:47 Tom_itx that be the turnbuckle in the middle
08:48 GuShH hrm
08:48 Tom_itx turn your motor off, it's hrm'ing
08:49 GuShH I have the extractor tool, but I don't have the tie rod end one...
08:49 GuShH it's similar to a pulley remover from what I've seen
08:49 Tom_itx it's a fork
08:49 GuShH there are two types!
08:49 Tom_itx just fork it
08:49 GuShH the solid tapered fork or the extractor type
08:49 GuShH fork it all!
08:50 GuShH I may have to confess I do not own a fork.
08:50 Tom_itx actually i just leave the nut on a bit and pop it with a hammer
08:50 GuShH that was the general idea as to not damage the threads
08:50 GuShH or mushroom it
08:51 GuShH I've done similar work but never on this car, it's all too basic not to do it yourself though.
08:51 GuShH plus tools are forever.
08:52 GuShH I still have and use tools that were originally from my grandpa, then passed on to my dad and now I'm using them
08:53 Tom_itx zap0 and those added distractions is what kills drivers
08:53 GuShH look a russian
08:53 Tom_itx it's likely a government funded ploy to keep the population down
08:53 zap0 or worse, innocent by standers
08:54 zap0 vechiluar manslaughter should be treated with as much penalty as gun crime.
08:57 GuShH specially if they have priors
08:58 Tom_itx i'm all about an eye for an eye
08:58 GuShH I'm aware of many cases where famous people have killed innocent people with their vehicles and have never been to jail for it
08:58 Tom_itx would certainly save on taxes to house prisoners
08:59 GuShH do they ever "recover" ?
08:59 GuShH they were born and raised to be criminals, there's no recovery
08:59 GuShH it's all a joke
08:59 GuShH and if they killed once they'll kill twice.
08:59 GuShH what's one more?
09:00 GuShH bah now I feel like shooting something
09:00 GuShH bbl
09:01 zap0 i presume you are talking about people like Matthew Broderick... car murderer.
11:54 MrCurious can anyone explain what the brunette is holding? http://www.bbc.co.uk/news/world-asia-pacific-24796181 it looks ike a chopstick, but it does not fit the story....
11:55 MrCurious smelling salts or swabs for a cut
12:47 defaultro afternoon folks, I hope you can help me. I can't figure out from the datasheet which pin is the output - http://www.pcbheaven.com/datasheet/irf540.pdf
12:50 defaultro found it, :) http://engenhocas4you.files.wordpress.com/2012/04/trsw07.jpg it's pin2
19:51 rue_house output...
19:51 rue_house common source I presume
22:09 rue_shop2 kat, can you find a price that beats $2 ea for "R8" bearings?
22:10 rue_shop2 maybe I wont worry about it, thats not really a bad price
22:10 rue_shop2 I cant beleive I have no 1/2" bearings
22:10 rue_shop2 its just crazy
22:32 rue_shop2 oh hmm, I have a 15mm shaft that fits the pulley, dont know how much that helps tho
22:40 MrCurious hi rue hows life
22:40 rue_shop2 hmm
22:40 rue_shop2 can I get a ticket vertifying I'm actually alive?
22:41 rue_shop2 certifying even
22:41 MrCurious well thats the thing about trying to aassert lilfe.. cant really distinguish experimentally if what you percieve is the product of existence or simulation
22:42 MrCurious very slippery thought, try to pretend you dont see it... you will live happier
22:42 MrCurious if lliving is indeed what you are doing
22:42 rgantuaSauce_ brings up schmidh
22:43 GargantuaSauce_ http://www.youtube.com/watch?v=T1Ogwa76yQo
22:43 MrCurious for all i know, i am a creature in a opaque vat of nutrients, and the world is simply how i perccieve that
22:44 MrCurious hahahahahaha
22:45 MrCurious i want to be shot before the german gives his speech
22:45 GargantuaSauce_ he tells the same jokes in EVERY ONE of his talks
22:47 MrCurious its a good joke
22:47 MrCurious i haver heard the german give his speach...
22:49 evil_dan2wik MrCurious, We are just a figment of your vast imagination
22:49 MrCurious alas, the worse case scenario rears its ugly head
22:49 MrCurious forever alone
22:50 evil_dan2wik Hey, I'm just stating the truth here.
22:50 MrCurious that cant be rght, i have a WAY better imagination than this
22:50 evil_dan2wik Can you imagine your mom having sex with obama?
22:51 MrCurious i will never be able to un-imagine THAT much leather. tyvm
22:59 MrCurious so we are just a 3 dimensional projection of a n-dimensional neural network homing in on the ideal set of training values
23:00 evil_dan2wik #confusion'
23:00 MrCurious GargantuaSauce_: thanks. good video, scratches that is it real itch
23:01 GargantuaSauce_ yeah it's a pretty interesting argument
23:01 GargantuaSauce_ that guy's work really turns my crank in general
23:01 GargantuaSauce_ http://www.idsia.ch/~juergen/goedelmachine.html
23:01 MrCurious the important question issnt are we real or simulation
23:02 MrCurious no matter which we are, we are likely identical to the other
23:02 GargantuaSauce_ yeah it's a moot point
23:02 GargantuaSauce_ my favourite line from that talk (or maybe another one, not sure) is "everything looks like a nail when you're a hammer"
23:03 MrCurious whats everything look like if you are an alcoholic?
23:03 MrCurious i dodnt think it all looks like a beer
23:03 GargantuaSauce_ which in the context of him being a world-leading AI scientist and the talk being about a simulated universe is pretty fucking funny
23:03 MrCurious but might as well as blurry as it would be
23:04 GargantuaSauce_ everything looks like a means to get more beer, duh
23:05 MrCurious that would explain the strange accumulation of computers i have been noticing of late
23:09 MrCurious looking like monday, like friday will be a furlough day
23:11 GargantuaSauce_ everyday is robot day
23:44 defaultro Hey folks, I just ordered a bipolar 4 wire stepper motor. Am I right that I won't be able to drive it with my TIP122?
23:46 GargantuaSauce_ you can drive it with four of them in an h bridge configuration but driving the high side is probably a bit ambitious for you at this point to be honest
23:46 Triffid_Hunter defaultro: no you won't. you need a proper driver for bipolar, eg the drv8825 or A4982-based ones that folks have been pointing you at these past few days
23:46 defaultro cool
23:48 defaultro What if I build my own controller, I can just get the A4982 chip right?
23:49 GargantuaSauce_ if you are prepared to read and understand the entirety of its documentation and comprehend the dynamics involved enough to design a pcb to carry it, sure
23:49 GargantuaSauce_ but that's putting the cart before the horse
23:50 Triffid_Hunter defaultro: you don't have the skills to handle a bare A4982 chip
23:51 evil_dan2wik Are you sure he doesn't?
23:51 GargantuaSauce_ yes
23:51 Triffid_Hunter defaultro: it has a thermal pad underneath which MUST be connected to some sort of heatsink- usually a large copper pour on the back of a PCB with thermal vias
23:51 defaultro yup, just saw it
23:53 defaultro looks like it needs an oven
23:53 Triffid_Hunter defaultro: I've done a dozen or so with hot air, works well enough. iron would be almost impossible
23:54 defaultro i don't have the tools
23:54 Triffid_Hunter unless you had a big plumber's iron or something and then you're likely to burn the pcb
23:54 GargantuaSauce_ apparently a skillet will do in a pinch too
23:54 defaultro never heard of hot air. Looks like i want that tool :D
23:54 GargantuaSauce_ you need a lot more knowledge first
23:54 defaultro :)
23:54 GargantuaSauce_ tools are secondary to that
23:55 evil_dan2wik You need to have a PCB to put the chip on. You need a way to solder the chip, and you need the chip + other components.
23:55 Triffid_Hunter defaultro: http://triffid-hunter.no-ip.info/101_0110.JPG <-- did this mostly by hand with hot air for most of the chips
23:55 defaultro looks like this A4982 only supports 2A. That's not enough. I was hoping it can support at least 5A so if I buy a stronger motor in the future, it will still work
23:55 defaultro Amazing dude! Great job!
23:56 Triffid_Hunter defaultro: for that sort of current, the chip will need external mosfets. see A4989 for example
23:56 GargantuaSauce_ i would say start with the monolithic solution
23:56 evil_dan2wik Triffid_Hunter, where did you get the miniSD card slot?
23:56 defaultro k
23:56 defaultro GargantuaSauce_: what is monolithic solution?
23:57 defaultro single chip?
23:57 Triffid_Hunter evil_dan2wik: it's microSD, don't recall exactly where it came from.. element14 or digikey or sparkfun or one of those places
23:57 evil_dan2wik ok.
23:57 defaultro any other part better than A4982 that will handle better current?
23:57 Triffid_Hunter defaultro: also, if your crappy unipolar motor is strong enough with 1A, why do you need 5?
23:57 Triffid_Hunter defaultro: drv8825 goes to 2.25A
23:57 GargantuaSauce_ http://www.timjarvis.com/wp-content/uploads/2012/04/Monolith_03.jpg
23:58 defaultro just in case in the future I buy another higher torque motor
23:58 GargantuaSauce_ yes, single-chip solution
23:58 defaultro ok
23:58 Triffid_Hunter defaultro: then get a higher current driver to go with it
23:58 defaultro that's what I just asked
23:58 GargantuaSauce_ what he's saying is design for now
23:58 Triffid_Hunter defaultro: no I mean get it if you buy a bigger motor
23:59 Triffid_Hunter defaultro: stick with the A4982 for now, you'll have enough to learn to not blow it up as it is and these ones are at least fairly cheap
23:59 defaultro ok
