00:22 rue_shop3 I raked down the whole driveway and then sprayed 250L of water from my rain barrel on it using the pressure washer as a pump/sprayer!
00:29 MrCurious is it winter there still?
00:35 rue_mohr2 its canada, its always winter
00:35 rue_mohr2 we live in igloos ya know
00:35 rue_mohr2 even our computers are made of ice
00:38 rue_mohr2 http://www.ebay.ca/itm/Silver-Tone-Chrome-Plated-1-2-PT-Male-Thread-Basin-Mixer-Tap-Faucet-/231088857749
00:38 rue_mohr2 hahaha they designed it backwards!
00:44 rue_mohr2 "it says to only use for hot water" "thats ok, I cant read it"
00:44 orlock rue_mohr2: Finally got that geared stepper turning again
00:45 rue_mohr2 ah, that would be fun to sequence
00:45 orlock wired it up as unipolar, and all of the coil pins happened to be in the right order so it just worked
00:46 rue_mohr2 why not use a shower head for the kitchen sink?
01:15 rue_mohr2 http://www.ebay.ca/itm/Kitchen-Hexagon-Hole-Water-Spout-Tap-Basin-Faucet-Silver-Tone-/271186563612
01:15 rue_mohr2 4/5" eh?
01:28 MrCurious very utilitarian
01:28 MrCurious the shower heads in my college dorms were capable of slicing tomatos and onions...
01:29 MrCurious that may go a little bit to the why not...
01:30 rue_mohr2 the only disadvantage i can think of is filling a cup or bottle
01:32 rue_mohr2 http://www.ebay.ca/itm/New-G-1-4-Threaded-Air-Pneumatic-Pedal-Valve-Foot-Switch-2-Way-2-Position-/121303579410
01:32 rue_mohr2 I'm usually good at valve symbology, but, wtf?
01:33 Jak_o_Shadows It's just not quite right is it
01:33 MrCurious so uhm, 1 pedal for hot, one for cold, one makes a reving sound, the other makes a screetch sound
01:34 rue_mohr2 2 position, seems to have 2 ports, but the diagram seems to indicate 3 postions and 3 ports
01:34 rue_mohr2 with the middle position being wtf
01:35 Jak_o_Shadows I would tend to think two position, one being pressure to the thing, the other pressure being released from the thing.
01:35 Jak_o_Shadows With uh, released as default?
01:35 MrCurious could be analog... variable presure in direct relation to depression
01:35 rue_mohr2 they dhow the spring on the one end
01:35 rue_mohr2 show
01:36 rue_mohr2 aha
01:36 MrCurious default closed?
01:36 rue_mohr2 http://www.ebay.ca/itm/SNS-Foot-Press-Control-PT-1-4-Threaded-Air-Pneumatic-Pedal-Valve-/171376673709
01:36 rue_mohr2 zoom in and you can see the cast in diagram thats done properly
01:36 rue_mohr2 it vents one or the other
01:37 rue_mohr2 which make sthe other diagram make more sense
01:37 MrCurious so a foot pedal ti direct the shower to back, or rain head from above...
01:37 MrCurious i could see a set of these appealing to a profesional drumer in search of an exciting bathroom experience...
01:37 Jak_o_Shadows That's what I interpreted it as
01:38 rue_mohr2 I'm comming up wioth a custom kitchen tap solution
01:38 rue_mohr2 something involving foot controls
01:38 MrCurious why not go with the kohler one that you temp set, and it senses your proximity, and turns on at prefered temp
01:38 rue_mohr2 cause, often my hands are busy
01:38 MrCurious with led to iluminate water temp between red and blue...
01:38 MrCurious you dont touch that one, a wave is enough
01:39 MrCurious and having a foot pedal operated kitchen sinck is very wheel chair unfriendly...
01:39 rue_mohr2 yea yea
01:39 MrCurious think of your golden years mate
01:40 rue_mohr2 if I end up in a wheel chair I'll be sure to build some legs so I can operate the sink
01:40 MrCurious thanks for the image of an army of ironman suit clad 90 year old pensioners
01:40 rue_mohr2 http://www.ebay.ca/itm/Silver-Folding-Brake-Shift-Pedal-Foot-Lever-For-Suzuki-GSXR-600-750-1000-06-10-/141333824394
01:41 rue_mohr2 there is a nice tap control pedal
01:41 MrCurious i think hospitol OR's use this solution for scrubbing up
01:41 rue_mohr2 yup
01:41 rue_mohr2 @~$800+
01:41 MrCurious the cooler solution would be ultrasonic hand cleaners.....
01:42 MrCurious if that would even work...
01:43 rue_mohr2 no, its like fire, but its wet
01:43 MrCurious you mean liquid fire?
01:43 rue_mohr2 and if anyone offers you some bacon mcflurry, decline!
01:54 rue_mohr2 http://www.ebay.ca/itm/1-PCS-1-4-2-Position-5-Way-Air-Pneumatic-Foot-Pressure-Control-Valve-ST-402A-/171254351493
01:54 rue_mohr2 oh yea!
01:56 rue_mohr2 its ok to have a compressor under the sink if its to operate a cool pedal like that, right?
05:49 SquirrelCZECH well
05:49 SquirrelCZECH am I blind or there is no "photography" related channel on IRC?
06:27 deshipu SquirrelCZECH: I'm sure there are some, you just have to find the right server
06:27 deshipu SquirrelCZECH: I would start with irc.gimp.org
07:01 Tom_itx apparently there's #photo but you need an invite
07:25 Carpate i have a friend with an odd situation we're trying to trouble shoot, and maybe one of you can help us. working with an odroid x2 and getting a system shutdown when it is put in a vacuum chamber for testing. any ideas what could be failing when it sees negative pressure?
07:28 deshipu Carpate: are you sure it's the pressure, and not the temperature?
07:31 Carpate temp reads 42C at shutdown
07:33 Carpate the time of shutdown is predictable once vacuum is applied
07:33 Carpate i'm thinking maybe to encapsulate the entire board, but it's not my project to be making decisions.
07:35 deshipu the only thing that comes to my mind is the electrolytic capacitors
07:36 Carpate ya, same here,
09:06 rue_mohr2 SquirrelCZECH, #avr started with like 5 of us from robotics,
11:25 esakish What's the easiest way to discharge a capacitor
11:25 esakish ?
11:29 billmania The "easiest" way? Short the leads.
11:29 MrCurious tongue
11:30 MrCurious kidding... dont do that
11:30 billmania However, that's not always the safest way.
11:30 MrCurious shorting can be dangerous
11:30 MrCurious perhaps a discussion on the size specs of the cap are in order
11:31 billmania Or, a quick bit of reading: http://www.wikihow.com/Discharge-a-Capacitor
11:43 esakish Thanks
11:49 deshipu incapacitate a capacitor
12:26 MrCurious on a lighter note, never play hot potato with a charged capacitor in a lab with your lab mates. no never do that...
12:27 Tom_itx Kv?
12:31 esakish I was thinking of the very small capacitors
12:38 MrCurious https://www.youtube.com/watch?v=8Gv0H-vPoDc
19:39 Guest78332 any electrical engineers in the house?
19:43 SlaveToTheSauce well i guess i know enough to be a danger to myself and others
19:43 SlaveToTheSauce will that do?
19:43 Guest78332 lol maybe
19:44 Guest78332 If I have a motor that needs 16.8 volts and batteries don't come in that size I"m assuming I need to join 3 12 volt batteries together but how do I use just 16.8 per a motor, 2 motors
19:45 SlaveToTheSauce with what are you planning on driving this motor?
19:45 Guest78332 you mean signalling?
19:45 SlaveToTheSauce switching
19:45 Guest78332 arduino
19:46 Guest78332 was that what you were asking?
19:47 SlaveToTheSauce nope. it's a scintillating piece of information though.
19:47 Guest78332 lol maybe you can clearify the question?
19:48 SlaveToTheSauce well the microcontroller can only push about 10mA of current right. something needs to take its signal and use it to control the much larger amount of current that will be driving the motor right
19:48 SlaveToTheSauce do you have something in mind for that role already?
19:49 Guest78332 I could be totally wrong but I was under the impression a mosfet is like a switch that can be switched on and off by a low current?
19:49 SlaveToTheSauce that is correct and will suffice
19:49 Jak_o_Shadows the amount of current depends on how fast you want it to switch, i thnk
19:49 SlaveToTheSauce yeah we'll assume reasonably low frequencies for now
19:50 SlaveToTheSauce so you're fine with the motor only going in one direction?
19:50 Guest78332 I wanted the arduino to signal the mosfet allowing current flow, bad idea?
19:50 Guest78332 well shit I didn't consider that
19:50 Jak_o_Shadows Some mosfets require higher voltage levels than the arduino can output
19:50 Guest78332 how would you do it?
19:50 SlaveToTheSauce if you want both directions you need an arrangement called an h-bridge
19:51 SlaveToTheSauce how much current is the motor rated for?
19:51 Guest78332 16.8 volts is all I know don't know the amperage
19:52 SlaveToTheSauce well this is a piece of information that is necessary for choosing a driver
19:52 Guest78332 will research brb
19:53 SlaveToTheSauce also to answer the original question, you can drive it with a higher voltage (24V sounds fine) if the duty cycle is decreased proportionally so that it's running at the same power as it would at the rated voltage
19:54 Guest78332 yea I don't speak spanish
19:54 Guest78332 duty cycle
19:54 SlaveToTheSauce it's the proportion of time that it's switched on vs switched off
19:55 SlaveToTheSauce you'll be driving it in pulses, the width of which will determine the duty cycle
19:55 Guest78332 ah, I was going to have it run constant when running like digital signal/ wide open
19:55 SlaveToTheSauce yeah that'd be fine but only if you had a power supply of the rated voltage
19:55 Guest78332 no way to reduce/filter?
19:56 SlaveToTheSauce the technique i've described is how you reduce the average power, without wasting the remainder (which is very significant) as heat
19:56 SlaveToTheSauce this way you also get speed control
19:57 Guest78332 ok
19:57 SlaveToTheSauce http://en.wikipedia.org/wiki/Pulse_width_modulation
19:57 SlaveToTheSauce http://en.wikipedia.org/wiki/H-bridge
19:57 Guest78332 I'm looking for the amperage but dont' see it
19:57 SlaveToTheSauce is there a power rating?
19:57 Guest78332 http://www.amazon.com/Traxxas-Titan-Motor-10-Turn-Volts/dp/B001SETT0Y/ref=sr_1_1?ie=UTF8&qid=1405470879&sr=8-1&keywords=power+wheels+traxxas+16.8+volt
19:59 SlaveToTheSauce you might just want to use the sort of brushed ESC that's designed specifically for that class of motor
20:00 SlaveToTheSauce and then control that with the arduino's Servo class
20:00 Guest78332 esc?
20:00 SlaveToTheSauce electronic speed controller
20:00 SlaveToTheSauce exactly the device you'd see in an rc car using that motor
20:00 Guest78332 ok...how do I know where to find that?
20:00 SlaveToTheSauce i imagine there's a few under the same brand
20:00 SlaveToTheSauce look for brushed esc
20:01 orlock does servo class let you control directly via pwm now?
20:01 Guest78332 that specific motor goes in a power wheels
20:01 SlaveToTheSauce orlock: is that not what it does?
20:01 SlaveToTheSauce i dunno i can't stand the very notion of those arduino libraries
20:01 Guest78332 lol
20:02 SlaveToTheSauce but it's what we're working with here and i can't be assed to evangelize better architectures
20:02 orlock SlaveToTheSauce: From what i remember it abstracts it out to position
20:02 orlock same as the basic stepper libraries are crap too
20:03 Guest78332 I'm a total noob when it comes to robotics or circuitry just working on my first project so what setup would you suggest?
20:03 SlaveToTheSauce get brushed escs rated for like...50A or something
20:03 SlaveToTheSauce just eyeballing it
20:03 SlaveToTheSauce maybe more
20:04 SlaveToTheSauce they will accept a standard rc pulse signal
20:04 orlock yeah, easy enough to control via the arduino
20:07 SlaveToTheSauce http://hobbyking.com/hobbyking/store/__32025__HobbyKing_X_Car_45A_Brushed_Car_ESC.html
20:07 SlaveToTheSauce something like that
20:07 Guest78332 what does this piece do?
20:08 SlaveToTheSauce oh shit it only does 10V or so
20:09 Guest78332 I also have no way of knowing the amps or wattage
20:09 Guest78332 on this motor
20:09 SlaveToTheSauce yeah that is a bit of a problem
20:09 orlock i use cordless drill motors and a pololu driver
20:09 SlaveToTheSauce i take it you're replacing the electronics of the car in the interest of automation?
20:10 orlock but that wont give you the power of a brushless/esc
20:10 Hyratel Guest52561, post a pic of the motor and I'll shoot a guess
20:10 orlock Guest78332: refitting kids toy?
20:11 Guest78332 http://www.amazon.com/Traxxas-Titan-Motor-10-Turn-Volts/dp/B001SETT0Y/ref=sr_1_1?ie=UTF8&qid=1405470879&sr=8-1&keywords=power+wheels+traxxas+16.8+volt
20:11 Guest78332 no here's the entirety of the project...
20:11 Hyratel is that a brusned motor? i only see two colors of leads
20:12 SlaveToTheSauce yes
20:12 Hyratel then you don't use a Brushless ESC
20:12 Hyratel you need a DC PWM motor driver
20:12 SlaveToTheSauce which is why i've been saying brushed
20:13 Hyratel Guest78332, please use /nick NEWNICK to get yourself a name we can call you by
20:13 Guest78332 I have a weed eater engine driving an alternator charging car batteries that drive the motors, arduino for signalling, rasberry pi for the brains and network connection, cdma connection to control over the cell network, and it is going to be a tank with a functional turrent
20:13 Hyratel .....
20:13 SlaveToTheSauce sounds a bit complex for a first project
20:13 Hyratel what is a name you call yourself
20:14 NEWNICK poe
20:14 Hyratel make a name out of that and use the /nick command to name yourself
20:14 NEWNICK it won't let me change it now
20:14 SlaveToTheSauce http://www.ebay.ca/itm/320A-High-V-Brushed-ESC-Speed-Controller-for-RC-1-10-Off-road-Car-Truck-Crawler-/261533538959
20:14 Hyratel NEWNICK, why won't it?
20:14 NEWNICK that motor goes to a power wheels off road
20:14 NEWNICK lol
20:15 SlaveToTheSauce running at 12V should be fine, it won't have all the grunt that the motor might otherwise provide but it will likely suffice
20:15 Hyratel if the name is already taken, it won't let you. it has to be sufficiently unique that it won't collide with another nick
20:15 SlaveToTheSauce (and the original application probably ran at 12V)
20:15 Hyratel also don't buy from sketchy ebay sellers
20:15 orlock http://www.pololu.com/product/1451
20:15 Hyratel do not buy that ESC that SlaveToTheSauce linked
20:15 SlaveToTheSauce if it's >99% positive i'm sure it's fine
20:16 Hyratel buy yourself something reputable from pololu or Andymark
20:16 Hyratel http://www.andymark.com/Talon-p/am-2505.htm
20:16 orlock 5.5 to 24V, 12A sustained 30A peak
20:16 SlaveToTheSauce i suspect the motor will draw much more than that
20:16 Hyratel I do not trust non-brand parts
20:16 SlaveToTheSauce anyway i am not going to do this being contradicted at every turn
20:16 SlaveToTheSauce so have fun
20:17 poe1337 so what amperage should I use for this one? since it is not labeled?
20:17 Hyratel judging by the weight of the wires it might do between 25 and 30 A
20:17 Hyratel BUT
20:17 Hyratel you'll want to do some bench testing
20:17 orlock http://www.pololu.com/product/758
20:18 orlock 24V 25A without heatsink
20:19 Hyratel how much space do you have for a motor?
20:20 Hyratel how much budget do you have?
20:21 poe1337 reasonable budget, as much space as I need I'm building the chasey
20:21 Hyratel chassis
20:21 poe1337 that too
20:21 poe1337 I'm welding the chassis and tracks myself
20:21 Hyratel http://www.andymark.com/product-p/am-2493.htm
20:22 orlock poe1337: also, sla may be a better bet than car batteries
20:22 Hyratel that system will do upwards of 80 lbs robot
20:23 Hyratel http://www.andymark.com/Controls-Packages-s/381.htm
20:24 poe1337 I kinda wanted to do the hard work myself
20:24 Hyratel uh
20:24 Hyratel you are
20:24 poe1337 and learn something
20:24 Hyratel you're building it
20:24 poe1337 lmao that's not hard
20:24 poe1337 I want to understand the circuitry
20:24 Hyratel so you don't want a turnkey control system?
20:24 Hyratel hang out in here and you will
20:24 orlock poe1337: got multimeter and breadboard?
20:25 poe1337 yep
20:25 poe1337 I have both, I might get a turn key system after I slam my head into the wall a couple times
20:25 poe1337 but I want to try first
20:25 Hyratel your cellphone control is a good system to use as an upgrade
20:26 Hyratel but do yourself a favor PLEASE and get a turnkey system
20:26 poe1337 lmao, I love your confidence in me
20:26 Hyratel I've been in FIRST robotics for nine years
20:26 SlaveToTheSauce and do your best to spend 3-5x as much as it's worth
20:26 Hyratel https://dl.dropboxusercontent.com/u/33593534/images/Robot/DSCN2012.JPG
20:27 Hyratel do you have an Xbox 360 conroller?
20:27 Hyratel wireless
20:27 poe1337 I know I'm going to blow money but it is better to learn something and build something than just a kit car
20:27 poe1337 yes I do
20:28 Hyratel get a USB Host Shield (sainsmart) off amazon
20:28 Hyratel a USB xbox controller reciever ($6-9 amazon)
20:28 Hyratel some servo cables and header pins (wherever)
20:29 Hyratel an Arduino Protoshield (there are a lot of them available)
20:29 Hyratel and you have the arduino
20:29 Hyratel it'll have 100 ft line of sight range
20:29 poe1337 I think I have all of that, except the USB host shield? and 360 reciever I do have some 360's I can tear down
20:30 Hyratel no no no
20:30 Hyratel you buy a USB reciever for it for the computer
20:30 Hyratel much more durable
20:30 poe1337 ok I do have some none functional 360's lying around though
20:30 Hyratel that won't do you much good
20:30 poe1337 ok
20:31 Hyratel the receivers in them are too purpose-built
20:31 poe1337 gotcha
20:31 Hyratel it's not a turnkey system, but it's a step up from what you were trying to do - way too rube goldbergian command chain
20:32 Hyratel the RasPi is not a realtime OS
20:32 poe1337 what do you mean?
20:32 Hyratel you might have as much as a quartersecond between sending it a command and the response - even if that command is "all stop"
20:32 orlock its a hardware platform
20:32 poe1337 right it is going to be over cdma anyway talk about lag
20:33 Hyratel the arduino does run in realtime, and the XBox controller radio is plenty of range to get started with
20:33 Hyratel the USB host shield is ... uh, $30
20:33 poe1337 what is it?
20:33 Hyratel what's what?
20:33 orlock poe1337: you can get cheap transceivers that will talk serial and give you a decent range too
20:34 poe1337 I've seen those, what is a usb shield?
20:34 Hyratel the USB host shield allows you to plug a USB slave device (in this case, an XBox360 wireless controller radio dongle) and have it talk to it as if it was a computer
20:34 orlock into your arduino
20:34 poe1337 oh ok
20:35 Hyratel http://www.amazon.com/Xbox-360-Wireless-Gaming-Receiver-Windows/dp/B000HZFCT2
20:35 Hyratel http://www.amazon.com/Wireless-Gaming-Receiver-Replacement-XBOX/dp/B007NIQ9AW/ref=sr_1_6?s=videogames&ie=UTF8&qid=1405473411&sr=1-6&keywords=wireless+gaming+reciever
20:36 Hyratel poe1337, look through Andymark's motors and gearbox selection. they have a lot of parts that are designed to work well together
20:36 Hyratel http://www.andymark.com/Single-Speed-Gearboxes-s/205.htm
20:37 Hyratel a CIMple box (4.75:1) and a 4:1 chain drive is about as fast as you probably want
20:37 orlock Or, cordless drill motors
20:37 Hyratel a CIM is ~4700 RPM at peak torque
20:37 orlock pre-geared, cheap, etc
20:37 Hyratel those would work too, but they're pretty turnkey :P
20:38 poe1337 yea I have a feeling I"m going to try and frankinstein what I already have
20:38 Hyratel you can't frankenstien an ESC
20:38 Hyratel well you could but it's MUCH more advanced design than you know
20:38 poe1337 true I do need to buy that
20:39 Hyratel I reccomend the ones Andymark carries
20:39 Jak_o_Shadows I'm half-tempted to use the gate drivers, mosfets, hip4082, and a uC to make one for myself. But I have a feeling i'd stuff up actually soldering it
20:39 poe1337 but I already have a chassis, motor, arduino, ras pi, verizon card and
20:39 poe1337 I can solder
20:40 orlock Say. Anybody here in aus?
20:40 poe1337 as long as it's not a micro surface mount
20:40 Jak_o_Shadows There is a few orlock
20:41 poe1337 how else would you learn besides saying fuck it and build it?
20:41 Hyratel I had to replace the FETs in a car inverter
20:42 Hyratel thankfully it was single sided through hole for the drivers
20:42 Hyratel they took up less boardspace that way
20:42 poe1337 I don't know what a FET
20:42 Hyratel Field Effect Transistor
20:42 poe1337 sounds cool
20:44 Tom_itx http://tom-itx.no-ip.biz:81/~webpage/temp/hip4081_bridge.png
20:45 Hyratel Tom_itx, is that four lowside NFET
20:45 Tom_itx ja
20:45 Tom_itx 40-50A
20:46 Hyratel why are you inverting the dir pin?
20:46 Tom_itx for ALI BLI inputs
21:04 poe1337 just found out this is the esc I"m suppose to use
21:04 poe1337 http://traxxas.com/products/parts/escs/3019Revx2lvd
21:05 Hyratel O_o
21:05 Hyratel how much is the traxxas motor
21:05 Hyratel you',ll need one of those for each side
21:06 poe1337 already got both of them
21:06 Hyratel wait
21:06 poe1337 you are right
21:06 poe1337 oh and fyi traxxas had no idea of the amperage on the engine
21:07 poe1337 the guy on there support was kinda of a ignorant dick
21:08 Hyratel pfft that's hilarious
21:08 Hyratel what do you ahve in drive parts anyway
21:09 Hyratel and how big is your tank going to be
21:09 Hyratel http://www.rctankcombat.com/articles/track-systems/
21:10 Hyratel you may not be wanting turnkey, but there's resources out there to bootstrap your design process
21:10 Jak_o_Shadows ok. 15" laptop screen liberated
21:10 poe1337 well damn
21:10 Hyratel poe1337,
21:10 poe1337 yea
21:10 Hyratel how big were you thinking?
21:10 Hyratel curb weight
21:10 Hyratel https://dl.dropboxusercontent.com/u/33593534/images/Robot/DSCN2011.JPG
21:11 Hyratel this is nearly 60 lb
21:11 poe1337 idk cubic weight, probably dimensionally 3-4 feet long, 3 feet wide, and pretty sure I'm going to use a .223 barrel
21:12 orlock .223
21:12 Jak_o_Shadows I hope you can ride on that Hyratel
21:12 orlock "That Gun"
21:12 poe1337 2 feet high
21:12 Hyratel Jak_o_Shadows, nope
21:12 Hyratel but mainly because the tires are too squishy
21:12 orlock poe1337: know how to make tracks?
21:12 poe1337 yep
21:12 Hyratel poe1337, sounds like you're going to have a 60-90lb curb weight
21:12 Jak_o_Shadows That's disappointing
21:12 orlock poe1337: bike chains and split tubing?
21:13 Hyratel it CAN pull someone on an office chair
21:13 Hyratel the tires just have too much rolling resistance when it has a payload
21:13 poe1337 chain to sprocket drive, with metal plates tacked on to the chain
21:14 poe1337 just like in hyratel's link
21:14 Hyratel orlock, ther's a bunch of designnes on that site i linked
21:14 poe1337 don't think I"m doing bicycle chain though
21:14 orlock hjf: Wheres that? Main difference is impedance i thought
21:14 Hyratel poe1337, you'll need an ajustable axle on one end because chains stretch over time and you can't take halflinks out of a bolted-chain track
21:15 poe1337 I saw a much heftier chain I'm going to use
21:15 Hyratel #35 rollerchain?
21:15 Hyratel https://dl.dropboxusercontent.com/u/33593534/images/Robot/DSCN2015.JPG
21:15 Hyratel this is using #35
21:15 Hyratel those are 10" tires
21:15 poe1337 no this was time belt chain or something
21:15 Hyratel use #35
21:16 Hyratel you can get sprockets to fit it ANYWHERE
21:16 poe1337 yea but was worried about breakage
21:16 Hyratel don't
21:16 Hyratel #35 is ... plenty
21:16 poe1337 lol mine's not a drive it is the actual structural integrity of the "tire"
21:17 Hyratel so?
21:17 Hyratel #35 is still fine
21:17 Jak_o_Shadows Ha. Laptop screen is actually http://www.alibaba.com/product-detail/LT141X6-122-14-1-XGA-1024_506181905.html
21:17 poe1337 I'm going to drive the shit out of it, you don't think it will break
21:17 Hyratel you're making this harder on yourself than it needs to be
21:17 Hyratel I drive the shit out of Hormes (that R/C i keep linking pics of
21:18 Hyratel I've had to take up half links as the chain stretched over months of hard driving
21:18 Hyratel trust me
21:18 Hyratel I'm as close to an expert as it gets without being paid
21:18 poe1337 lmao
21:18 Hyratel 9 years messign with this shit
21:18 poe1337 Alright
21:18 Hyratel I'm reasonably sure I know what I'm doing
21:18 poe1337 I'll try it your way
21:19 poe1337 lol reasonably sure of yourself huh....that's encouraging
21:19 Hyratel and for your internal drive systems I do reccomend Andymark parts
21:19 poe1337 I know where you work
21:19 poe1337 :P
21:19 Hyratel I'll never say "completely sure" - that way lies hubris
21:20 Hyratel the motors are 2.5" CIMs
21:20 Hyratel they'll handle ridiculous amounts of amperage
21:20 poe1337 I already bought theses though
21:20 Hyratel how much each?
21:20 Hyratel to wire up a CIM would cost you
21:20 Hyratel CIM - $28
21:20 Hyratel Talon - $60
21:21 Hyratel to wire up those traxxas would be
21:21 Hyratel Motor - $30
21:21 Hyratel ESC - $160
21:21 poe1337 I got two of them
21:21 poe1337 damn the esc is that much?
21:21 Hyratel send them back and get CIMs
21:21 Hyratel yep
21:21 poe1337 FUCK
21:22 SlaveToTheSauce or get the $20 one i linked to
21:22 Hyratel http://traxxas.com/products/parts/escs/3019Revx2lvd
21:22 Hyratel actually $180
21:22 Hyratel and you'd need two of them
21:23 Hyratel and it isn't designed for SLA batteries either
21:23 Tom_itx treadmill or wheelchair motors
21:23 Tom_itx plenty of those discarded every year
21:23 Hyratel yeah send back the traxxas motors and get some less-proprietary motors
21:23 Hyratel Andymark parts all work together
21:24 poe1337 lmao
21:24 Hyratel just get the right variety
21:24 Hyratel probably a 12:1 or higher toughbox mini
21:24 Hyratel http://www.andymark.com/tbmini-options-p/am-tbminioptions.htm
21:24 Hyratel oh, it only goes down to 12:1
21:25 Hyratel http://www.andymark.com/Power-s/263.htm
21:26 fghfghjfg Curious typically how high breakers/fuses are installed in a residential/home for an electrical circuit in theory one could make any rated amp circuit breaker and a large enough gage wire but in practice for homes is it 50 amp breakers and 8 or 6 gage wires or do they run bigger gage wires and circuit breakers in the house. Not counting the transformer to the meter that is a different story
21:26 Hyratel fghfghjfg, slow down
21:26 Hyratel grab the wall
21:26 Hyratel wiggle like you tryna make your ass falloff
21:26 Hyratel now please ask your question in a way that makes sense
21:26 orlock fghfghjfg: here its 10 or 15A breakers
21:27 poe1337 alright guys I gotta go to bed I'll hit y'all up tomorrow good talk
21:28 fghfghjfg Well I have an amper rating chart with the wire gages but I am curious what is used for the circuits in a house is the highest one usually 50 amps or does it get normally higher then that I cann't imagine much higher sense most circuit boxes or the highest rated ones I see in houses are 200 amps
21:29 orlock fghfghjfg: Depends on the country
21:29 orlock fghfghjfg: Some backwards nations run ~110v AC systems
21:29 Hyratel orlock, watch your language, them's fightn' words
21:30 orlock Hyratel: Sorry
21:30 orlock Hyratel: I'll talk slowly from now on
21:30 orlock :P
21:30 Hyratel *squint*
21:31 fghfghjfg 14 or 12 gage seem like the most often used for all the circuits in a houses definitely for lighting , fans ,...etc rangers and bigger appliances maybe 10 or 8 gage but curious where the 6 and lower are used hell they even have 1000 gage which supports up to500 to 600 amps
21:32 SlaveToTheSauce not all wiring is household
21:33 Hyratel fghfghjfg, my stove uses paired 10awg
21:33 Hyratel that's not 1000
21:33 orlock fghfghjfg: Lead between car battery and starter
21:33 Hyratel that's 1/0
21:33 Hyratel and 1/00, 1/000
21:33 fghfghjfg 1/0 to 4/0 seem to be the gages range used for the transformer to the meter / meter to the main breaker bus bars/box
21:34 fghfghjfg know there is a difference between 1/0 ... 1000 on a chart
21:35 Hyratel the largest Iv'e worked with is 6
21:35 fghfghjfg was that in home circuit
21:35 Hyratel nope
21:35 fghfghjfg what was it
21:35 Hyratel http://www.andymark.com/product-p/am-0009.htm
21:35 fghfghjfg 50 amp or so need
21:35 Hyratel this high power
21:35 Hyratel 120A peak
21:36 Hyratel look up FIRST robotics on youtube
21:40 fghfghjfg Ok but I am curious typically in an type of house what amp circuits would be the biggest would it ever get over 30 amps or 40 amps basically would an electrican typically uses greater then 8 gage wire from the circuit breaker box to thru out the house to run a circuit ?
21:41 Hyratel first, break your statements into thoughts with periods
21:41 fghfghjfg typically in an = " " any
21:41 orlock fghfghjfg: All depends on who is living there. If they need it, they may just gut the house and install new wiring
21:41 Hyratel second, the largest circuit i know of in my house is the stove which is 30+30 split phase
21:42 orlock They are on the news every few weeks
21:43 fghfghjfg so they are probably installed with 10 or 8 gage wire
21:43 orlock Why dont you look at your local building codes?
21:46 fghfghjfg Well I know what wires corospond to what amps. And I know in a circuit breaker box I normally only see 15,20 amp breakers but I know there are heater/ranger devices that require more amps. But what I would like to know is in terms of applicances in a house which ones are the biggest amps/power users. If I know this then I would know the largest gage wire found in 99.9999% of houses
21:47 fghfghjfg And what the biggest amps are for these appliances
21:48 orlock fghfghjfg: Generally things that generate heat by shorting through a resistive load
21:49 fghfghjfg is 30 amp circuits normally the biggest in houses because I have seen them selling 50 and 60 amp breakers So curious what thoses would be used for obviously you would be using 6 or 4 gage wire
21:49 orlock fghfghjfg: Marijuana grow houses.
21:49 orlock fghfghjfg: Bitcoin farms
21:49 SlaveToTheSauce my stove is on a 50A breaker
21:50 fghfghjfg so did they uses 8 or 6 gage wire ?
21:50 SlaveToTheSauce mayeb
21:51 SlaveToTheSauce you should look at your local building codes.
21:51 Hyratel fghfghjfg, check local build code
21:51 Hyratel end of debate
21:51 Hyratel end of topic
21:51 Hyratel that will have your answers
21:53 fghfghjfg O so those are what the building codes and all this time I was saying who needs these building codes but in actuality the codes is just what I am doing any way it is an up to date version of what should be used and the reasoning complies with the theory for the most part
21:54 SlaveToTheSauce are you on drugs?
21:55 orlock maybe just american
21:57 Hyratel hey, i take umbrage to that
21:57 Hyratel he's worse than just "american".
22:08 fghfghjfg Well it looks as for appliances electric ... oven,ranger, hot water heater seem to be the highest wattage consumed so if they where on a 120 they would need breakers maybe as high as 66 amps but if they are on 240/220 volt circuits seems as they would be fit on to a 30 amp circuit with a 30 amp circuit breaker. So it seem higher amp breakers have little uses in residential circuitary / home circuitary
22:10 fghfghjfg Your stove must have been a 120 volt 50 amp breaker if I am correct :)
22:10 orlock fghfghjfg/: All depends - i found the 10A breakers kept tripping when i was shorting current across the gimps nipples
22:10 Hyratel fghfghjfg, go away please
22:10 Hyratel you're clogging the tubes with your shit
22:13 orlock homework maybe?
22:14 Hyratel orlock, he's acting too stupid to be a studen
22:14 Hyratel t
22:23 fghfghjfg Wait a minute what happens if your houses is really huge wouldn't not only the amps/ wattages of the appliances / devices be an issue but also the length of the circuit ... ohms per foot would eventually create more resistance enough to bump the wire up to a smaller gage to get
22:23 fghfghjfg the result
22:23 Hyratel fghfghjfg, local building codes
22:23 Hyratel go away from here and look them up
22:23 Hyratel there are rules to handle that case
23:07 MrCurious wow, gushh is taking the loss hard
23:45 rue_mohr2 and there is, in the universe, a completely valid sentance that consist of the same word repeated 7 times, it does , each itteration of the word does of course need to be emphasized properly for it to have meaning.
23:45 rue_mohr2 it does , of course, need to have each..
