10:58 katsmeow-afk i was looking forwards to it being 55F today, but i don't see that happening, it's still only 40F now
10:58 katsmeow-afk http://blogs.discovermagazine.com/d-brief/files/2015/02/SAFFiR1.jpg <<== broken, FF won't show it
10:59 katsmeow-afk what's a GExif ?

11:07 katsmeow-afk hand requires bearings for cables---the rubbing--destroys the plastic----the plastic is very fragile
11:07 katsmeow-afk <<== that's why i went with those 5mm OD ball bearings
11:08 katsmeow-afk or 8mm, i forget now
11:08 katsmeow-afk but the best cord i could find was orange, which was too close to red, so iscrapped the whole thing
18:04 katsmeow-afk well, looks like the woman stayed in the suv because it was cold outside, and did not try to drive off the tracks because she didn't want to scrap the paint on the suv or the break-away crossing arm,,,,, so the train hit her, she died, and damage done
18:05 katsmeow-afk and i just bought a 2(3)-seater Ski-doo brand personal watercraft for $ 30
18:05 katsmeow-afk the obvious gotcha is: the engine is dead, and it's a two-cycle anyhow
18:06 katsmeow-afk errr,, and $ 100,000's damage done
18:07 tsmeow-afk growls at mirc ag

18:28 katsmeow-afk Former unlicensed day care provider Stephanie Gribble was sentenced to 10 years in prison by Judge Mark Stoner on Friday for drugging children in her care
18:28 katsmeow-afk drugs ,, judge Stoner?
18:45 katsmeow-afk so if i put a set of pontoons out to the sides of the skidoo, i can carry fuel out there instead of inside the engine compartment, where it's in a PLASTIC TANK IN THE ENGINE COMPARTMENT
18:45 katsmeow-afk and i can carry more, and added floatation, and it will be virtualy untippable
18:47 katsmeow-afk be a hoot to have a set of small car tires in the toons, so i can just drive it up the boat ramp and park near whereever building in the marina
18:52 katsmeow-afk i can't belive a gas tank in the engine compartment, if that thing went off while you were driving it on the ocean, there's no way to avoid gettomg your face burned off, even if you let go and pushed yurself off the back as the thing sped away
18:57 tsmeow-afk wonders why the channel is d
19:00 katsmeow-afk word order matters: the usa navy is advertising the one robot's job as being "useful in fighting fires", what they really mean is "useful in fire fights"
19:59 tsmeow-afk wonders if Tom wrote an irc cl
20:00 Tom_itx ?
20:00 Tom_itx why would i do something like that?
20:00 katsmeow-afk . 7:39:45pm 02/06/15 Friday Tom_itx quit: Ping timeout: 250 seconds . <<== you keep doing that
20:01 katsmeow-afk it's usually caused by not responding to the server PING , or appearing dead
20:01 tsmeow-afk solved the latter issue by : * Timer 2 120s delay pingmy
20:02 katsmeow-afk it makes the server happy, and so it doesn't disconnect meevery 250 seconds <shrug>
20:06 katsmeow-afk i need to putmy feets into the FootRoaster for a while, bbl
20:07 Tom_itx gettin 66v across GNDs isn't a good thing
20:09 rue_more wow
20:09 rue_more 66 is almost half of 120
20:10 rue_more 66 ac or dc
20:10 rue_more something didn't blow up again did it?
20:12 Tom_itx no
20:13 Tom_itx but i'm trying to connect the DAC to the drive
20:13 Tom_itx so i can control the speed with the program
20:14 Tom_itx http://tom-itx.no-ip.biz:81/~webpage/cnc/PDF/
20:14 Tom_itx the KBIC is the one i have
20:15 Tom_itx i checked it to the control frame too and get similar voltages
20:16 rue_more what is the 66 across
20:17 Tom_itx F- on the drive and the frame of the control
20:17 rue_more from what supply
20:17 Tom_itx F- & I2 are connected
20:17 Tom_itx the frame is on the main control
20:18 Tom_itx i don't know where else to connect the GND on the drive unit
20:18 rue_more this could be your blowup?
20:18 Tom_itx no
20:18 Tom_itx it has nothing to do whith that
20:18 Tom_itx this is new unbroken ground
20:19 Tom_itx both plugged into the same outlet
20:19 Tom_itx unless you can find me a better GND on that pdf
20:20 rue_more oh, F- is the field
20:20 rue_more do you have a permanent magnet motor?
20:20 Tom_itx but it's connected to I2 which is the negative portion of the voltage divider going to the P2
20:20 Tom_itx yes
20:21 Tom_itx field isn't used
20:21 rue_more you dont connect F, either of them
20:21 Tom_itx if it had field windings you would
20:21 Tom_itx but i don't
20:22 rue_more so what are you worried about connecting them to?
20:22 rue_more just dont connect them
20:22 Tom_itx i ned to connect them
20:22 Tom_itx the 10v DAC goes to P2
20:22 Tom_itx for control of the drive speed
20:22 Tom_itx and it needs a GND return path
20:23 Tom_itx can you find another GND point there?
20:23 rue_more uh
20:23 rue_more I doubt this is isolated properly for what your trying to do
20:23 Tom_itx it has been done before
20:23 Tom_itx but they don't say where to connect GND
20:23 rue_more I doubt this is isolated properly for what your trying to do
20:24 rue_more maybe an optically isolated serial link to a digital potentiometer?
20:24 Tom_itx this board i have was supposed to work for this
20:24 rue_more I doubt this is isolated properly for what your trying to do
20:24 Tom_itx one sec...
20:25 Tom_itx yeah that's the 3rd time you said that
20:25 Tom_itx i get it
20:25 rue_more Voltage Following ? All models can be controlled with an isolated analog reference voltage (0-7 VDC) in lieu of the main
20:25 rue_more speed potentiometer. The voltage is connected to P2 (+) and F-. The control output voltage will linearly follow the input voltage.
20:25 rue_more The source impedance of the input should be 10K ohms or less. The Min and Max trimpots are rendered inoperative in the
20:25 rue_more voltage following mode. Use auxiliary trimpots for scaling and to limit the control range. If the input signal is not isolated, or
20:25 rue_more is a current signal (4 - 20 mA), the KBSI-240D or SI-5 Barrier Terminal Board Signal Isolator must be used. It will allow direct
20:25 rue_more connection to process controllers and microprocessors.
20:25 Tom_itx i also get the fact that others have done it
20:25 rue_more an isolated analog re
20:25 rue_more yours isnt' isolated
20:25 Tom_itx mmm
20:25 rue_more they made the design simple by referencing the control power off part of the 120V
20:26 Tom_itx yeah i figured that
20:26 rue_more optically isolated serial potentiometer
20:26 rue_more search maxim datasheets
20:27 Tom_L http://www.cnc4pc.com/Store/osc/product_info.php?products_id=58
20:27 rue_more they love to put in examples of that stuff
20:27 Tom_itx this is controlled from 0-10v
20:27 Tom_itx an industry standard
20:27 Tom_L http://cnc4pc.com/Tech_Docs/C6R6%20and%20KB120%20V1.pdf
20:28 Tom_L the connections
20:28 rue_more a relay based stepper driver, evil
20:28 rue_more oh, its for induction motors
20:28 _moon hay
20:29 rue_more _moon, hey
20:29 Tom_itx oh wait... maybe if i connect GND to the other side of the pot...
20:29 Tom_itx like they show
20:29 rue_more want to take apart a nuclear power plant?
20:29 Tom_itx the MIN pot
20:29 Tom_itx see?
20:29 rue_more Tom_itx, your gonna blow er up
20:29 Tom_itx the lower 2 wires are the DAC out and GND
20:29 _moon could i throw a question in the mix
20:29 Tom_itx this is how they connect this board to my controller
20:30 rue_more the - ref on the pot is at 66V off ground, if that, the 66 your seeing is prolly part of a 120V 60Hz power signal thats partially rectified
20:30 Tom_itx i agree
20:30 rue_more Tom_itx, 8 bit serial 10k pots aren't tooo expensiv
20:30 rue_more and can be isolated with 6N137
20:31 rue_more or a million other ways
20:31 rue_more million ways of isolating a 0-10V
20:31 rue_more kat, would you name a few?
20:31 Tom_itx why would they show something that won't work?
20:32 rue_more they want you to buy more junk
20:32 rue_more or blow it all up and buy another set
20:32 Tom_itx i'm gonna hook it there once and see if it blows the GFCI again
20:33 rue_more again!?
20:33 rue_more think on this
20:33 _moon i got a c question for you dan
20:33 rue_more your shorting a recified 120V to your controllers ground signal
20:34 rue_more go for it
20:34 rue_more not you Tom_itx
20:34 rue_more Tom_itx, I really dont suggest connecting that
20:34 rue_more _moon, you ask question
20:34 _moon if a guy wanted a mechanism to call a function with a command line argument or an int from scanf
20:35 rue_more you would need a lookup table, remember the fucntion names dont exist in the machine code
20:36 _moon yes but could a guy inject string value maybe into function name?
20:36 _moon wait no
20:36 _moon cuz what you just said
20:36 _moon :P
20:37 Tom_itx ok rue_more, i agree... this isn't going to work as is
20:37 Tom_itx ( no i didn't blow anything up )
20:37 rue_more I'm sure 0-10V opto isolators are a dimea dozen from china
20:37 Tom_itx i need a different drive unit
20:38 rue_more why not use the one you have and get a isolator for it
20:38 Tom_itx how will the 0-10v analog out hook to it?
20:39 rue_more http://www.aliexpress.com/item/High-Accuracy-1-5V-0-5V-Voltage-to-2-wire-4-20mA-Output-Isolation-Transmitter-0/32241177852.html
20:39 rue_more still searching tho
20:40 rue_more http://www.aliexpress.com/item/0-10V-to-0-10V-3000VDC-Isolated-DIN14-IJY-V2-P2-V2-12VDC-Power-Supply-1/1751044219.html
20:40 rue_more these thigns aren't cheap
20:41 Tom_itx this is a rue cheap project
20:42 rue_more how about convertering the 0-10V to AC, putting it thru a transformer, and then rectifying it?
20:42 Tom_itx i can get a motor control made for the job
20:42 rue_more use square wave,
20:43 rue_more little ferrite core
20:43 Tom_itx i'm going to stick with the industry standard 0-10v input to a device
20:43 rue_more for less than $32?
20:43 Tom_itx the last one was 139
20:43 rue_more did you open the first one?
20:43 Tom_itx yep
20:44 rue_more the price averages $80
20:44 rue_more which surprises me
20:44 Tom_itx there is a driver that will work if i can find it again
20:44 Tom_itx takes 120v in and converts it with no external supply
20:44 rue_more like I say, I think its not harder than a 555, 1:1 signal transformer and a bridge rectifier
20:45 Tom_itx took me day and a half to scale the 10v to spindle speeds between 10 - 5000 rpm
20:46 Tom_itx not wanting to take 2 steps back to take one forward
20:46 rue_more http://www.aliexpress.com/item/4-20mA-to-0-5V-0-10V-Converter-1-5KV-Isolation-DC-Current-Voltage-Converter-DIN/1821999544.html
20:46 rue_more DIN 1X1 BET-U2-P2-O5
20:47 rue_more and you need a 12V supply on the driver side (isolated)
20:48 rue_more tho they seem to indicate the power is isolated from both
20:49 rue_more which is verry plausable
20:53 rue_more ali is escro, so they make sure you get your stuff
20:53 rue_more w^
20:53 Tom_itx this board was free btw...
20:53 Tom_itx dude didn't need it for his
20:53 rue_more hah, likley story
20:54 Tom_itx no, he is using different drivers now
20:55 rue_more whats the motors voltage range from 10-5000rpm?
20:55 rue_more 5-24?
20:56 Tom_itx umm .011 - 10.08v
20:56 Tom_itx but i need to tune it more
20:56 Tom_itx once the drive is hooked up to it
20:56 Tom_itx this was just done with a meter and logic analyzer
20:56 rue_more do you need the motor driver to do the regulation?
20:57 Tom_itx it's a DAC from my control box
20:57 Tom_itx either this DAC or another one
20:57 rue_more http://www.aliexpress.com/item/400W-24V-Single-Output-Switching-power-supply-for-LED-Strip-light-AC-to-DC/621192132.html
20:57 rue_more I'm no genious, but that little pot ont eh side of the barrier strip
20:57 rue_more dials that power supply down quite a ways
20:58 rue_more and it can be ref'd off your logic ground
20:58 rue_more tho I dont know what the signal is, which gives you a 50/50
20:58 rue_more I have one, I should check
20:59 rue_more I think they exist cheaper
20:59 rue_more not by a lot tho
21:02 rue_more _moon, what you up to?
21:02 Tom_L http://www.a-m-c.com/products/analog_brushless.html
21:02 rue_more Tom_itx, doyou know if the motor pulls more than 20A?
21:03 rue_more "brushless"
21:03 Tom_L i doubt it
21:03 rue_more and I'm gonna ballpark the controller is ~$200
21:03 Tom_L it's a tiny motor
21:03 Tom_L as motors go
21:04 rue_more I'v thrown you some options, I'm gonna stop searching and fall asleep
21:04 rue_more I know you will go with none of them
21:05 rue_more I have a motor sped controller I bought from ebay, max rated 20A 60V (chineese amps and volts)
21:05 rue_more it uses a 555, I'v not checked if it can do 0-100%
21:05 rue_more I think the pot control would be easily hacked
21:06 rue_more http://www.ebay.ca/itm/400780894895?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
21:06 rue_more mm
21:06 rue_more http://www.ebay.ca/itm/400780894895
21:07 rue_more I should play with it and give you an update
21:07 rue_more _moon, what you up to?
21:08 Tom_L well i'm gonna sit on it a while
21:09 rue_more katsmeow-afk, https://ciis.lcsr.jhu.edu/dokuwiki/lib/exe/fetch.php?media=courses:446:2012:446-2012-05:bentmanipulator.jpg
21:09 rue_more nifty!
21:11 rue_more hmm how could I make a connector that would allow for connecting/disconnecting a set of tendons all at once
21:11 rue_more er, I mean drive cables
21:13 m_L sets this on the shelf where rue_more's reprap set for a w
21:14 Tom_L can a light bulb cause back emf?
21:14 Tom_L if it blows out under a load
21:15 rue_more no
21:15 Tom_L so if it were used as a load and the bulb blew it wouldn't cause any damage
21:17 rue_more http://www.etsmtl.ca/Unites-de-recherche/coro/Documents/MedRUE_400px.png -> counterweights, anyone EVER heard of them?
21:17 rue_more Tom_itx, correct
23:00 katsmeow-afk .
23:09 rue_shop3 -
23:09 Tom_itx _
23:10 rue_shop3 anyone ever notice how the universe is laid out like the discharge path of an electrical arc?
23:11 katsmeow-afk no
23:11 rue_shop3 why not?
23:11 Tom_itx more like water down a drain
23:11 katsmeow-afk why did i never notice it? i didn't look
23:12 rue_shop3 not he galaxy, the universe
23:12 rue_shop3 when you look at the layout of all the galaxies, they form a path like a electrical discharge
23:12 Tom_itx i'm not worried about the universe, i'll never make it past our galaxy anyway
23:14 rue_shop3 and in about 2 billion years its all gonna fade out anyhow, but thats not my point
23:14 Tom_itx i liked the fact that the GCIF blew during my testing
23:16 katsmeow-afk err, congrats?
23:16 Tom_itx well it saved my ass
23:16 Tom_itx ... so to speak
