[00:00:06] <andypugh> The R1 is surprisingly comfortable, better than the FJ1100 on a long ride. But only if the speed is > 30mph
[00:00:08] <PetefromTn_> the R1 is a lot more short, snappy, and lighter than the big fizzer
[00:00:42] <PetefromTn_> really...I would not have thought that. I have ridden quite a few R bikes
[00:00:50] <PetefromTn_> My best friend has an R6
[00:01:05] <andypugh> I find it practical enough to have been my only transport for 11 years.
[00:01:11] <PetefromTn_> we often traded bikes
[00:01:16] <PetefromTn_> WOW
[00:01:23] <andypugh> The R6 is quite a lot smaller.
[00:01:39] <andypugh> 97,500 miles and counting...
[00:01:41] <PetefromTn_> my wife did not like riding on it with me near as much as she did on the big FZR
[00:01:53] <PetefromTn_> are you kidding me?
[00:02:00] <andypugh> Yeah, pillion on the R1 is hopeless.
[00:02:02] <PetefromTn_> that is a TON of miles
[00:02:20] <PetefromTn_> she used to like riding with me on the FZR tho.
[00:02:38] <andypugh> I doubt that many R1s have done more miles, but some probably have.
[00:02:48] <PetefromTn_> I love the Ducati 999 because it is both beautiful and has a nice pass seat
[00:03:05] <PetefromTn_> and I love the looks of the Suzuki TLR1000R
[00:03:15] <PetefromTn_> I got a think for fast twins....

[00:32:56] <CaptHindsight> they're going for the low hanging fruit, sintering nylon and ABS at low resolution
[00:33:21] <LeelooMinai> Right, but nylon wrench - that's a bit misleading:)
[00:33:37] <CaptHindsight> certainly

[00:34:47] <CaptHindsight> they are all monkey see, monkey do. They aren't even trying to make functional parts with low cost materials at high res and high speed.
[00:35:21] <LeelooMinai> A lot of hype and voodoo about 3D p rinters
[00:35:42] <CaptHindsight> everyone seem to just be making a maker quality 3d printer with 20-30 year old tech
[00:35:45] <LeelooMinai> People buy them, print a Yoda head, and that's that
[00:35:54] <CaptHindsight> they are just in it for the quick buck
[00:36:46] <LeelooMinai> There must be a lot of 3d printer projects on kickstarter

[00:38:35] <LeelooMinai> Seems like a wheel

[00:39:04] <LeelooMinai> Wheel for some robot? :)
[00:39:06] <PetefromTn_> looks like it is made of glued up sand LOL
[00:39:33] <LeelooMinai> Maybe when you clean it up it looks better (?)
[00:39:54] <CaptHindsight> no, that is it sintered
[00:40:06] <CaptHindsight> you'd have to machine it to clean it up
[00:40:16] <CaptHindsight> so why not just machine it?
[00:40:21] <PetefromTn_> almost looks like it needs to be wire brushed and cleaned up LOL
[00:40:33] <PetefromTn_> but then again NOT

[00:40:56] <CaptHindsight> this one is better
[00:41:23] <CaptHindsight> but it shows how clueless they are by using these models as examples

[00:42:04] <PetefromTn_> I love how one of those advertisement photos shows what looks like a bearing
[00:42:23] <LeelooMinai> Maytbe it's supposed to suggest that the printer makes parts that are strong as metal
[00:42:30] <CaptHindsight> SLS can make functional parts
[00:42:45] <PetefromTn_> a bearing?
[00:42:46] <CaptHindsight> LeelooMinai: you think they are trying to get suckers to think that?
[00:43:01] <LeelooMinai> I am sure some people would think that, yes
[00:43:08] <CaptHindsight> not actually say if but get you to assume that

[01:07:52] <PetefromTn_> a pair of nothing maybe
[01:08:13] <CaptHindsight> it used to be different, I used to restore old cars
[01:08:35] <CaptHindsight> we'd have a box or stack of titles for one complete car

[01:11:24] <PetefromTn_> there is a fellow who made one from a clean Yamaha FZR400 which was quite a nice bike back in the day.
[01:11:54] <CaptHindsight> PetefromTn_: are the bikes without titles 5 cents on the dollar?
[01:12:12] <PetefromTn_> some of the production prototypes of these electric bikes are quite fast and powerful
[01:12:26] <PetefromTn_> actually not generally which is what amazes me...

[01:48:32] <zeeshan> hey guys im having trouble cokming up with a routine for my power drawbar routine
[01:48:48] <zeeshan> when tool change command button is pressed in linuxcnc
[01:48:59] <zeeshan> it turns on the hydraulic pump for 30 seconds
[01:49:25] <zeeshan> it also takes the input from the pressure switch.
[01:49:42] <zeeshan> so when i press the "tool change requestion button" this is what happens.
[01:51:29] <zeeshan> tool change request (momentary button NO) -> 7i77 input -> check vfd is on? ok. check pressure is reached? ok. check if spindle is off? ok. check if m06 g-code is active? ok. -> when all conditions are met energize solenoid for hydraulic pressure to drawbar
[01:52:12] <zeeshan> my concern is it doesnt seem safe
[01:52:17] <zeeshan> because it's all done through linuxcnc
[01:54:11] <zeeshan> all it takes is a noise spike
[01:54:26] <zeeshan> on the too change request input
[01:54:32] <zeeshan> and it seems like things can go haywire
[01:54:51] -!- ejb has quit [Quit: ZZZzzz…]
[01:54:53] <zeeshan> (these are 24vdc signals)
[01:54:57] <PetefromTn_> does your machine have an automatic tool changer?
[01:55:04] <zeeshan> yes
[01:55:14] <zeeshan> well by automatic
[01:55:19] <zeeshan> i dont mean it loads it by itself
[01:55:21] <zeeshan> its a power drawbar
[01:55:23] <zeeshan> hydraulic
[01:55:43] <zeeshan> http://www.youtube.com/watch?v=n39CqxrhkVg&list=UUy-Z-COl0WvPmSLXMOvtedg
[01:56:13] <PetefromTn_> then the answer is no... so if the spike you are talking about happens all that will occur is that the hydraulic pump will cycle. Nothing happens until YOU press the power drawbar button no?
[01:56:47] <zeeshan> check that video out to see the interface
[01:57:03] -!- ktchk [ktchk!~eddie6929@n219073004118.netvigator.com] has joined #linuxcnc
[01:57:30] <zeeshan> hmm..
[01:57:38] <zeeshan> im worried about a spike on the solenoid signal wire
[01:57:51] <zeeshan> or for some reason 7i77 goes haywire
[01:57:57] <zeeshan> and changes the states of the output
[01:58:17] <zeeshan> cause i was planning to have an output directly from 7i77 to the solenoid
[01:58:24] <zeeshan> so i dunno if there is a computer freeze
[01:58:31] <zeeshan> and for some reason the 7i77's outputs change state
[01:58:39] <zeeshan> it might trigger the solenoid while the spinddle is running
[01:58:42] <zeeshan> that could be dangerous :/
[01:58:48] <PetefromTn_> why would you want anything but a physical button to release the tool?
[01:58:55] <zeeshan> well the idea was
[01:58:58] <zeeshan> to "add safety"
[01:59:07] <PetefromTn_> my machine has a disable while the spindle is in motion
[01:59:07] <zeeshan> for some reason i decide to press the physical button while the spindle is running
[01:59:11] <zeeshan> it wont let me
[01:59:15] <zeeshan> (cause it'll know the spindle is running)
[01:59:35] <PetefromTn_> you can push the button all you want and nothing happens
[01:59:40] <zeeshan> okay
[01:59:44] <zeeshan> so you have some sort of physical relayu
[01:59:48] <zeeshan> that interfaces with the spindle vfd?
[01:59:56] <PetefromTn_> it also does not work unless there is sufficient air pressure in the system.
[02:00:00] <zeeshan> which stops the power drawbar from working?
[02:00:04] <PetefromTn_> yeah
[02:00:06] <zeeshan> hmm
[02:00:09] <zeeshan> excellent way of doing it
[02:00:31] <PetefromTn_> works fine so far....
[02:00:45] <zeeshan> most vfds have these aux relays builtin
[02:00:49] <zeeshan> that are NC or NO
[02:00:50] <PetefromTn_> and I have accidentally pressed it before ;)
[02:01:00] <zeeshan> depending on a condition met in the VFD
[02:01:15] <zeeshan> so i would wire my 24vdc solenoid wire
[02:01:17] <zeeshan> through that relay
[02:01:22] <zeeshan> and through my physical switch
[02:01:28] <zeeshan> PetefromTn_: it happens
[02:01:35] <zeeshan> especially if i'm not paying attention
[02:01:37] <zeeshan> i could trigger it
[02:02:18] <PetefromTn_> it is a neccessary safety to be sure

[02:30:36] <zeeshan> on the 7i77
[02:30:39] <zeeshan> ill be using all 6!
[02:30:44] <zeeshan> 5 for each axis and 1 for spindle
[02:31:28] <PetefromTn_> that is a five axis machine?
[02:31:40] <zeeshan> NO
[02:31:43] <zeeshan> er sorry caps
[02:31:49] <zeeshan> (using autocad rofl)
[02:32:10] <zeeshan> its 3 axis but ill be throwing a rotary table for a and c axis
[02:32:31] <PetefromTn_> oh so 3+2
[02:32:33] <zeeshan> yes
[02:32:40] <PetefromTn_> interesting
[02:32:53] <PetefromTn_> I would not even know where to begin to program a machine like that.
[02:33:16] <zeeshan> i did a bit of 5 axis programming using mastercam for a plastic injectin place i worked at
[02:33:21] <zeeshan> like for a couple weeks
[02:33:24] <zeeshan> it was confusing as hell
[02:33:41] <zeeshan> like i dont know if you do this
[02:33:48] <zeeshan> but after your spit out some code from CAM
[02:33:54] <zeeshan> you read over it to make sure its sane
[02:34:04] <zeeshan> with 5 axis, it takes way too long
[02:34:08] <PetefromTn_> I really want to get a fourth axis built or bought so I can start playing with it and learn
[02:34:11] <zeeshan> its a mess

[02:34:20] <PetefromTn_> I usually just use a simulator
[02:34:53] <PetefromTn_> then run with movements slowed down to a safe level upon first run of virgin code
[02:35:23] <zeeshan> ah
[02:35:33] <zeeshan> sometimes i dont trust cam cause if the post processor is messed
[02:35:36] <zeeshan> it'll spit out junk code
[02:36:15] <PetefromTn_> yeah which again is why I run slow the first time so I can stop it before bad stuff happens
[02:36:32] <zeeshan> <-- to lazy
[02:36:32] <zeeshan> :D
[02:36:59] <PetefromTn_> the sim should show what is going on even if the post processor is messed up...

[02:38:00] <zeeshan> well you know something like circ interpolation modes?
[02:38:05] <zeeshan> theyre different between machines\?
[02:38:09] <zeeshan> some like the quadrant style input
[02:38:11] <zeeshan> some like full circle
[02:38:20] <zeeshan> if you're lucky you get an error in the machine
[02:38:24] <zeeshan> but sometimes it runs
[02:38:33] <zeeshan> so simulator shows it correctly
[02:38:35] <zeeshan> but machine does something else
[02:39:10] <PetefromTn_> sure but that kind of issue should have been proven out on much simpler code beforehand
[02:39:28] <zeeshan> basically youre saying i worry too much
[02:39:28] <zeeshan> :)
[02:39:43] <PetefromTn_> I think we all know that here :D
[02:39:57] <zeeshan> dude seriously before school and stuff
[02:40:00] <PetefromTn_> that is not necessarily a bad thing really
[02:40:09] <zeeshan> when i used to work on my car, i didnt take things seriously
[02:40:20] <zeeshan> when i look at some of my old pics, im like "WTF"
[02:40:21] <zeeshan> haha
[02:40:47] <zeeshan> now i stress myself out :/
[02:41:24] <PetefromTn_> honestly when it comes to machines I am a bit overly cautious, I would probably get a lot more done if I were a bit more adventurous.
[02:41:58] <zeeshan> hey dude
[02:42:01] <PetefromTn_> but my own machines I have far too much invested in them to take silly chances and I don't like crashes they scare the shit out of me.

[02:42:52] <zeeshan> you know what the worst thing is?
[02:42:56] <zeeshan> youre done wiring everything
[02:43:06] <zeeshan> and you realize you forgot to make a hole in the enclosure to pass a wire for something
[02:43:13] <zeeshan> and then you need to drill that crap while components are still in
[02:43:17] <zeeshan> and deal with the chips
[02:43:26] <zeeshan> that drives me insane
[02:43:29] <PetefromTn_> I have done that several times

[02:44:10] <zeeshan> i did similar
[02:44:31] <zeeshan> this time im building everything on a mounting plate
[02:44:43] <zeeshan> and keeping all communication wires between components on it
[02:44:51] <zeeshan> anything that goes external has a plug
[02:45:13] <zeeshan> so it'd be a matter of disconnecting external plugs and removing 4 plates to remove the entire assembly
[02:45:19] <zeeshan> (at least thats the plan)
[02:45:25] <PetefromTn_> that is not really practical for my machine but it would be nice
[02:45:29] <cnc4clay> I just finished installing the binary.hybrid.iso for 6.4 wheezy. It looked okay when I ran linuxcnc with the simulation but then I ran apt-get update and upgrade and linuxcnc doesn't work. What happened?

[03:04:19] <zeeshan> can someone please help me make sense of this manual
[03:04:30] <zeeshan> its saying both the output and input need a power supply?!?!
[03:04:42] <zeeshan> lime on the input connector "up means 5V supply"
[03:04:46] <zeeshan> 0V i guess is ground.
[03:04:53] <zeeshan> but what about on the output side?
[03:05:02] <zeeshan> whats the diff between up and sensor up
[03:05:24] <zeeshan> and why do both sides of the circuit need power?!

[03:11:54] <cradek> google isn't telling me much - people in 2010-2011 suggesting it's a hardware problem
[03:12:08] <cradek> can you just slap a different video card in?
[03:13:12] <cradek> if you can reproduce this consistently, it would be very interesting to know what particular package upgrade breaks it

[03:59:36] <renesis> shit goes from 1vpp analog signals to 5v digital signals, splitting analog and digital supplies is pretty common

[04:00:03] -!- FreezingCold [FreezingCold!~FreezingC@135.0.41.14] has joined #linuxcnc
[04:00:25] <renesis> are their chips on both sides
[04:00:29] <zeeshan> no
[04:00:30] <renesis> there
[04:00:31] <zeeshan> one side only
[04:00:43] <renesis> well then its prob not isolated
[04:02:12] <Tom_itx> so your encoder plugs in the input side and you use the output side to linuxcnc?
[04:02:28] <zeeshan> Tom_itx: yes thats the only logical solution i think
[04:02:35] <zeeshan> cause the analog signal if you look in that manual
[04:02:36] <Tom_itx> that's what it shows
[04:02:37] <zeeshan> is on the input side
[04:02:48] <zeeshan> it goes from a 10 pin input
[04:02:50] <zeeshan> to 12pin output
[04:02:56] <zeeshan> i just dont see how the power hooks up
[04:03:03] <renesis> yeah the encoder outputs 1vpp, this turns it into 5v pulses
[04:03:09] <zeeshan> renesis:
[04:03:11] <zeeshan> thats the other model
[04:03:12] <zeeshan> i have idp 101
[04:03:16] <zeeshan> its 11 uApp
[04:03:19] <Tom_itx> 5v on pin3
[04:03:32] <renesis> same shit, its an analog sine
[04:03:37] <zeeshan> Tom_itx: yes but if you look on the output
[04:03:41] <zeeshan> pin 12 also have a 5v
[04:03:44] <Tom_itx> GND on 4
[04:03:47] <Tom_itx> so?
[04:03:48] <zeeshan> so i dont understand why they have 2 5vs?
[04:03:59] <zeeshan> and whats sensor 5v?
[04:04:00] <Tom_itx> maybe it passes thru
[04:04:07] <renesis> yeah i was going to say test
[04:04:07] <Tom_itx> power to the sensor
[04:04:26] <zeeshan> okay so i should check for continuity
[04:04:29] <zeeshan> between both the "ups"
[04:04:32] <renesis> connect the output side, see if theirs power on the input connector
[04:04:34] <Tom_itx> i would
[04:04:46] <renesis> might be a diode or a vreg
[04:04:58] <zeeshan> its a little weird that the sensor 5v
[04:05:04] <zeeshan> is on the output (digital side)
[04:05:07] <zeeshan> that makes 0 sense to me.
[04:05:26] <zeeshan> i finally got my multimeter
[04:05:31] <zeeshan> so ican finally PROBE
[04:06:02] <renesis> how is it weird, its an analog supply
[04:07:23] <Tom_itx> they could separate the supplies for noise reasons
[04:08:23] <renesis> yeah on one encoder connector it looks like they have isolated shielding
[04:09:02] <renesis> on the other, looks like they have isolated sensor and digital power
[04:09:38] <Tom_itx> similar to split supplies on mesa cards where you have field power
[04:10:38] <renesis> most mixed analog digital ic have split supplies
[04:11:19] <renesis> zeeshan: yours might not even use the Sensor Up pin
[04:11:58] <Tom_itx> what's the pinout on the sensor itself?
[04:13:08] <renesis> theres lots of possibilities

[04:26:17] <zeeshan> okay
[04:26:26] <zeeshan> so when i probe between 1b on the input
[04:26:28] <cradek> old machines collect goop in their heat sinks and fans
[04:26:33] <zeeshan> to 2a, 2b, 1a, 1b on output
[04:26:36] <zeeshan> i get continuity
[04:26:38] <zeeshan> wut\!
[04:26:43] <zeeshan> makes no sense :P
[04:26:55] <zeeshan> why is there continuity between 0V and 5v!!
[04:28:49] <renesis> cap
[04:29:04] <renesis> must suck to know less about this shit than a moron
[04:29:39] <zeeshan> ok thanks for your help.
[04:29:50] <zeeshan> ill follow the traces myself and not require your help anymore
[04:29:52] <zeeshan> cu!
[04:29:57] <renesis> bye
[04:30:16] <zeeshan> obv you couldnt figure it out either
[04:30:20] <zeeshan> so that makes 2 morons
[04:30:23] <renesis> i just said cap
[04:30:58] <renesis> initially, you always get continuity on a drained supply
[04:31:37] <renesis> how long depends on how big the cap is, and how drained, meter just see current happened and calls it continuous
[04:32:23] <zeeshan> lol the traces
[04:32:28] <zeeshan> on the other side make it so easy to see whats going on
[04:32:45] -!- gennro has quit [Quit: Leaving]
[04:32:55] <zeeshan> the traces from 1b @ input side to 2b, 2a @ output
[04:32:56] <zeeshan> are connected
[04:32:57] <renesis> yeah does not look like a complicated pcba
[04:33:03] <zeeshan> duhhh
[04:35:15] <zeeshan> okay this is easy
[04:35:43] <zeeshan> 1a input (0v) is connected to 1a and 1b on ouput
[04:35:56] <zeeshan> everything else i dont care about
[04:36:18] <zeeshan> i think the reason there is a sensor up and sensor 0v to begin with
[04:36:26] <zeeshan> is because the idp181 model requires it
[04:36:30] <zeeshan> but mine doesnt use it
[04:36:46] <renesis> are they continuous
[04:36:53] <zeeshan> the traceS?
[04:37:07] <zeeshan> yes
[04:37:11] <zeeshan> theres no components in between
[04:37:13] <renesis> no the sensor uP on the in and output
[04:37:15] <renesis> at the pin header
[04:37:24] <renesis> then yeah, you dont have that
[04:37:41] <renesis> you have isolated shields, which is cool
[04:38:06] <zeeshan> on the input side?
[04:38:46] <renesis> the shield pins are prob gonnected to ground at the pcba connector
[04:38:50] <zeeshan> the pin 1a (input) which labels "inside sheild"
[04:39:05] <renesis> and then in the encoder they would be connected to shields that dont share the signal ground
[04:39:20] <zeeshan> goes to the raytheon rc4157m t9728 chip
[04:40:03] <zeeshan> on the datasheet
[04:40:07] <zeeshan> that pin is "-Vs"
[04:40:35] <renesis> its maybe negative rail
[04:41:11] <renesis> and inside shield might be the negative rail in the encoder
[04:41:36] <zeeshan> il need to check that
[04:41:38] <renesis> it says Vpp, which usually suggests gnd biased AC
[04:41:52] <renesis> which prob means negative rails
[04:41:57] <zeeshan> i was thinking up and 0v were the sensor power stuff
[04:42:10] <zeeshan> and inside shield was the sheild on the cable
[04:42:21] <renesis> -Vs might just be an analog ground
[04:42:29] <zeeshan> yea i am pretty sure its just a ground
[04:42:43] <renesis> and the raytheon chip just has it on a reference input

[04:43:53] <zeeshan> pin 11, aka -vs
[04:43:59] <zeeshan> is the reference pin like youre saying
[04:44:03] <renesis> quad amp, pretty fast, +/-20V
[04:44:05] <zeeshan> negative side
[04:44:18] <renesis> it prob has a negative rail
[04:44:34] <zeeshan> http://www.mouser.com/ds/2/149/Fairchild_datasheet-20-364953.pdf
[04:44:36] <zeeshan> page 7
[04:44:37] <renesis> prob has a >5 positive rail too
[04:44:40] <zeeshan> you can see pin 11 on the right
[04:45:31] <renesis> thats not a reference pin thats a psu pin
[04:45:40] <renesis> normal quad amp pinout
[04:46:04] <renesis> notice it doesnt exist in the block diagram
[04:46:06] <zeeshan> fak op amps
[04:46:13] <zeeshan> i dont get em
[04:46:16] <renesis> wow
[04:48:56] <zeeshan> im looking at the pinout from the glass scales
[04:49:01] <zeeshan> pin 9 literally says "Shield"
[04:49:07] <renesis> that shit has 5V of dropout voltage with a 15V bipolar supply
[04:49:13] <zeeshan> pin 4 is ground
[04:49:25] <zeeshan> renesis: you're speaking alien to me
[04:49:26] <renesis> of the opamp
[04:49:52] -!- swingley has quit [Ping timeout: 240 seconds]
[04:50:07] <LeelooMinai> I wonder why most of the VFDs on aliezpress are 220V at least
[04:50:08] <renesis> that opamp wont work with 5V supplies
[04:50:22] <zeeshan> renesis: ??
[04:50:26] <renesis> so theres a boost supply somewhere
[04:50:27] <zeeshan> heidenhain's spec says use 5v
[04:50:50] <LeelooMinai> zeeshan: DO you have some VFD for your machine?
[04:50:51] <renesis> well then the raytheon chip is diff
[04:50:56] <zeeshan> LeelooMinai: 3
[04:51:10] <renesis> zeeshan: whats vs+ connected to
[04:51:18] <LeelooMinai> zeeshan: How did you get them?
[04:51:44] <zeeshan> internets ebay
[04:51:47] <zeeshan> and ex-boss
[04:52:07] <LeelooMinai> Hmm... Chinese ones are almost all 220V
[04:52:20] <zeeshan> renesis: i cant tell
[04:52:23] <zeeshan> its hard to follow that trace
[04:52:30] <zeeshan> cause it flips over using pads
[04:52:32] <zeeshan> a bunch of times
[04:52:40] <renesis> what
[04:52:41] <zeeshan> but idid notice something else
[04:52:50] <renesis> are their coils on the board
[04:53:03] <zeeshan> theres a trace going from 2b aka 0v on input
[04:53:12] <zeeshan> to 1a
[04:53:17] <zeeshan> aka inside shield
[04:53:24] <zeeshan> its a small trace right at the connector
[04:53:51] <zeeshan> LeelooMinai: what hp
[04:54:21] <LeelooMinai> zeeshan: Well, you know, if I want to use normal socket I am limited to what, 15A or so, so 1600 watt
[04:54:21] <zeeshan> renesis: so that pretty much means
[04:54:23] <zeeshan> theyre both ground :P
[04:54:35] <zeeshan> LeelooMinai: so about 1hp then
[04:54:50] <LeelooMinai> zeeshan: Isn't that 2?
[04:54:55] <zeeshan> no
[04:55:11] <zeeshan> when you consider power factor correct
[04:55:14] <zeeshan> correction
[04:55:17] <renesis> 1hp = ~750W
[04:55:20] <zeeshan> you can only drive a 3 phase 1hp motor
[04:55:29] <zeeshan> when you use a 120vac single phase input
[04:55:49] <zeeshan> 1hp 220v motor that is
[04:55:53] <LeelooMinai> Well, it's supposed to be for a spindle
[04:56:21] <LeelooMinai> Not sure how to match all of this - normal 110V socket and 2.2 kW spindle
[04:56:23] <zeeshan> cheapest new one i could find was this one:
[04:56:42] <renesis> zeeshan: then theres either a boost supply, or they raytheon and fairchild parts are not equiv
[04:56:51] <zeeshan> renesis: prolly not equiv
[04:56:53] <zeeshan> and theres no coils
[04:56:55] <renesis> that opamp in the datasheet does not run at 5v
[04:57:06] <cnc4clay> +crandek: The computer had been working continuously for the past 3 months without a problem. I will take a look. If that doesn't solve it I will try installing just wheezy and see if that works. Take care and will check it tomorrow. Thanks
[04:57:13] <zeeshan> LeelooMinai:
http://www.factorymation.com/Products/FM50_115V/FM50-101-C.html
[04:57:14] <renesis> could be capacitive charge pumps or something goofy
[04:57:24] <zeeshan> but note that drive is a pos when it comes to communications
[04:57:27] <zeeshan> theres no modbus or anything
[04:57:34] <zeeshan> its a simple scalar drive.
[04:58:50] <zeeshan> out of the circuit boards ive seen
[04:58:55] <zeeshan> this heidenhain looks so pretty
[04:59:02] <renesis> ?
[04:59:09] <zeeshan> its nicely laid out
[05:00:08] <renesis> caps are placed too close to the connector insertion area on the right side
[05:00:09] <zeeshan> maybe its cause its not multilayered
[05:00:15] <zeeshan> like a motherbaord
[05:00:34] <renesis> it looks functional
[05:01:08] <renesis> which isnt bad, but it looked like some parts were difficult, or autorouted, because certain places look messy
[05:01:29] <renesis> and there are a lot of vias
[05:01:35] <zeeshan> http://i.imgur.com/4ttXlqf.jpg
[05:01:40] <zeeshan> even thats well layed out
[05:01:54] <renesis> thats sexy as fuck
[05:01:58] <renesis> thats totally different
[05:02:02] <zeeshan> from a mechanical perspective
[05:02:26] <zeeshan> i think its cause of the symmetry
[05:02:28] <zeeshan> and patterning
[05:02:46] <renesis> caps are too close if coupling can cause issues
[05:03:22] <renesis> symmetry and patterns are usually a good things, means the designer was sane and it prob wasnt just done by a computer
[05:03:45] <zeeshan> i dont know what they call it
[05:03:47] <renesis> the other board looks like a guy who barely cares throw down some parts, laid some power traces, and hit autoroute
[05:03:53] <zeeshan> but sometimes they do a wiggle on the traces
[05:04:09] <renesis> thats for inpedence matching
[05:04:11] <zeeshan> i think to either add resistance or make them
[05:04:16] <renesis> impedence
[05:04:16] <zeeshan> this doesnt have that
[05:04:25] <zeeshan> ah okay
[05:04:48] <zeeshan> LeelooMinai: wake up
[05:05:20] <renesis> you can add resistance and inductance, itll work with trace capacitance to whatever, another differencial trace, a ground plane
[05:05:28] <zeeshan> http://www.ebay.com/itm/EATON-NFX9000-MODEL-NFXF25A0-1-DRIVE-/171328674967?pt=LH_DefaultDomain_0&hash=item27e3fc1c97

[05:05:34] <zeeshan> er nm
[05:05:36] <zeeshan> .25hp
[05:05:47] <renesis> and create a filter to smooth signals, or to get rid of noise, or couple it to a diff pair

[05:13:38] <renesis> mixed electronics from that era blow my mind
[05:14:16] <CaptHindsight> it looks like CAD routed
[05:14:42] <renesis> one of exjobs had a b&k stroboscope, open it up and its like 8 boards stacked, edge to edge DIP IC, big caps, lots of ribbon cable
[05:15:14] <renesis> capthindsight: yeah everything exactly 45deg
[05:15:22] <CaptHindsight> I don't remember what we used back then for PCB CAD, it was manual
[05:15:33] <CaptHindsight> look closer lots of 90's
[05:16:03] <renesis> by the 90s, through holes and vias had teardrops, SMD was pretty common
[05:16:05] <CaptHindsight> http://i.imgur.com/4ttXlqf.jpg this board
[05:16:17] <renesis> lots of random angles and poly shapes
[05:16:50] <CaptHindsight> back in the 70's it was often drawn by hand
[05:17:06] <renesis> those boards are either ultra sexy or just scary

[05:22:16] <zeeshan> there isnt much symmetry
[05:22:24] <renesis> to what?
[05:22:25] <zeeshan> it looks like a mess

[05:22:38] <zeeshan> http://i.imgur.com/Thj9E8U.jpg
[05:22:39] <zeeshan> that one
[05:22:48] <renesis> wtf?
[05:22:55] <renesis> how much symmetry do you need
[05:23:12] <zeeshan> i dunno what those round this w/ a flat head indent in them are
[05:23:16] <zeeshan> maybe pots
[05:23:21] <zeeshan> they look randomly placed
[05:23:23] <renesis> analog preamp right on the inputs, drops down into an amp with chassis heatsink
[05:23:28] <renesis> and nice isolation on the psu
[05:23:38] <zeeshan> the resistors and caps on the right
[05:23:42] <zeeshan> arent in line
[05:23:48] <zeeshan> theyve got a weird offset
[05:23:56] <zeeshan> the inductor isn't in the middle
[05:23:57] <zeeshan> its offset too
[05:24:00] <renesis> so youd rather a lined up china board?
[05:24:09] <zeeshan> no
[05:24:13] <zeeshan> im sure it performs great
[05:24:15] <renesis> things end up where they end up for a good layout
[05:24:18] <zeeshan> it just doesnt look mechanically placed
[05:24:27] <zeeshan> it doesnt look visually nice to me
[05:24:33] <renesis> if you have to budge something to get clearance so you get better performance
[05:24:42] <renesis> why the fuck wouldnt you do it, if you knew better?

[16:21:56] <CaptHindsight> a few months ago somebody started a new wiki, but I'll have to look for the location
[16:22:03] <CaptHindsight> we build on Gentoo

[17:50:17] <zeeshan> what happens?
[17:50:21] * zeeshan has never tried this

[17:51:34] <fuzzy7k> Ok, I'll check it out. Thanks again.
[17:51:34] <SpeedEvil> zeeshan: If you mean there are two connections to the power supply only from the motor, and both are isolated - then yes - isolating only one will make it stop

[17:58:31] <zeeshan> need sanity check
[17:58:56] <zeeshan> DS is a pressure switch that trips when pressure reaches 20 bar. WS is a level indicator which opens if fluid level is low
[17:59:08] * DaViruz rebuilds the berlin wall to keep the east germans in
[17:59:30] <zeeshan> currently the control cabinet has a wire going from pin 1 of DS and pin 3 of WS & DS
[17:59:46] <zeeshan> so i'm imagining the wiring is like this:

[18:00:09] <Connor> what is DK ? :)
[18:00:19] <zeeshan> +24VDC -> pin 3 of WS (will be closed if fluid level is NOT low) -> pin 2 common of ds and ws -> pin 1 of ds (only when pressure has been reached) -> 7i77 input pin
[18:00:25] <zeeshan> this signal is basically an ERROR signal

[18:01:38] <zeeshan> er i messed that up.
[18:01:47] <zeeshan> sigh :P
[18:02:11] <zeeshan> control cabinet wire is going to pin 1 and 2. not 1 and 3.
[18:03:01] <Connor> right. 3 would be your common.. be it +24v
[18:03:21] -!- karavanjo has quit [Ping timeout: 255 seconds]
[18:03:28] <zeeshan> +24VDC -> pin 2 of WS (will be closed if fluid level is NOT low) -> pin 3 common of ds and ws -> pin 1 of ds (only when pressure has been reached) -> 7i77 input pin
[18:04:26] <zeeshan> this is confusing.
[18:04:37] <Connor> you may not need to connect pin 3 to anything.
[18:04:48] <zeeshan> yea i know that
[18:04:52] <zeeshan> its only pin 1 and 2 connected
[18:04:59] <zeeshan> but the thing is im not getting the operation.. im thinking this:
[18:05:14] <Connor> okay.. so, it's a NO and a NC switch in series...
[18:05:35] <zeeshan> if the input is @ 0VDC you know pressure has not built up so keep running the pump? (because there will be flow of electricity through level indicator switch, but not pressure switch)
[18:05:51] <zeeshan> if input is @ 24VDC that means pressure switch has closed
[18:05:58] -!- kb8wmc has quit [Ping timeout: 264 seconds]
[18:06:08] <zeeshan> but if level indicator switch is open, then input will be at 0VDC and the pump will keep running
[18:06:09] <zeeshan> which makes nos ense
[18:06:12] <zeeshan> * sense
[18:06:52] <Connor> well.. probe the switches and confirm the state they're in..
[18:07:03] <zeeshan> i did
[18:07:13] <zeeshan> i also have the manual which confrism it
[18:07:23] <zeeshan> level indicator opens if fluid is low. its NC.
[18:07:32] <zeeshan> pressure switch is NO. closes when reaches 20 bar
[18:08:09] <Connor> okay. So, have you checked to see if maybe 3 is grounded to chassis ?
[18:08:23] <zeeshan> no
[18:08:27] <Connor> if they're only running 1 & 2 to control ?
[18:08:28] <zeeshan> it doesnt ground to chassis
[18:08:33] <zeeshan> pin 3 has 2 wires going into it
[18:08:43] <zeeshan> from each switch's leg

[18:10:40] <zeeshan> if you look at the pic @ the terminal block
[18:10:49] <zeeshan> you'll see theres 2 brown wires connected @ pin3
[18:10:54] <SpeedEvil> Anyone in the UK have a preferred source of extrusions/... that delivers?
[18:11:00] <zeeshan> those brown wires are coming from DS+WS's switch legs
[18:11:33] <zeeshan> i wish i had paid more attention to this part of ripping out wires from the control cabinet
[18:11:41] <zeeshan> i honestly thought this was a self timed unit
[18:11:42] <zeeshan> but its not
[18:11:43] <Connor> Ok, throw a probe on #3 and to the chassis of the machine.. and see if it tones out.

[18:17:09] <zeeshan> nope
[18:17:17] <zeeshan> no continuity between pin 3 and chassis
[18:17:40] <Connor> and no signs of a broken wire or one that was suppose to go there ...
[18:17:45] <zeeshan> yep
[18:18:22] <zeeshan> my friend just gave me some info from his plc controlled central lubricator (similar to my central lubricator)
[18:18:54] <zeeshan> three alarms will be displayed: 1. if (external) pressure switch does not detect pressure 45secs after the motor is on 2. if (external) pressure switch detects pressure if lubrication is off and pause period has expired 3. if lubrication is locked with M84 command longer than 90secs
[18:19:25] <zeeshan> so it's a timed input.
[18:19:45] <Connor> okay.
[18:20:07] <zeeshan> so basically if input is at 0VDC for 45 seconds after motor is on, error is thrown (which will be the case if DS is open)
[18:20:36] <zeeshan> but if ds closes in that time period it will keep running
[18:20:43] <zeeshan> but if WS opens then input will go back to 0.

[18:23:17] <Connor> okay.. what are you confused about ?
[18:24:04] -!- md-2 has quit [Remote host closed the connection]
[18:24:12] <Connor> DS is present to make sure that pressure is present and maintained.. and if it's not.. it shuts down the pump because that most likely means a line broke.
[18:24:31] <zeeshan> yes
[18:24:42] <zeeshan> basically i have 4 conditions
[18:24:51] <zeeshan> that'll put things into alarm mode and turn off the pump
[18:26:03] <zeeshan> the other confusion is power to the pump
[18:26:13] <Connor> ok

[18:26:30] <zeeshan> pin 4 5 8
[18:26:34] <zeeshan> and ground ofcourse

[18:26:59] <zeeshan> SL1 is an light
[18:27:01] <zeeshan> *light
[18:27:14] <zeeshan> -an = a :P
[18:27:31] <Connor> okay. 5 has something written below it...
[18:27:38] <zeeshan> so its pretty clear that if i wire something to 5 and 8
[18:27:39] <Connor> I think it's a N.. that would be for Neutral
[18:27:41] <zeeshan> the pump motor turns on
[18:27:52] <zeeshan> mine is currently setup for 220V
[18:27:54] <zeeshan> so its L1 and L2
[18:28:09] <zeeshan> nothing is written below pin 5
[18:28:14] <zeeshan> its just a piece of crap there
[18:28:17] <zeeshan> i need to vacuum it out
[18:28:24] <zeeshan> i have no clue how metal chips got in there with the cover on.
[18:28:44] <zeeshan> nema 4 my ass!

[18:33:07] <zeeshan> yes
[18:33:08] <Connor> so.. that's only there if your using it 110
[18:33:55] <Connor> How many wires going into 8 ?
[18:34:33] <zeeshan> this iss such a bs wiring diagram
[18:34:42] <zeeshan> anyway enough whining
[18:34:50] <zeeshan> theres one wire coming from control cabinet to 8
[18:35:01] <zeeshan> and then there is another wire going to the coil of the motor
[18:35:13] <Connor> Okay.
[18:35:19] <Connor> I understand now.
[18:35:26] <Connor> 4 is a manual button.
[18:35:29] <zeeshan> yes
[18:35:42] <Connor> 8 is L1 or L2
[18:36:36] <Connor> so, 8 would be hooked up to a contactor int he control cabinet.
[18:36:51] <zeeshan> i think im gonna use a relay
[18:36:55] <Connor> questions is, were is the other end of the circuit.
[18:36:56] <zeeshan> cause its such a small amount of current
[18:36:58] <zeeshan> yes :P
[18:37:07] <zeeshan> the only thing that makes logical sense to me
[18:37:12] <Connor> is it on the motor itself.. ?
[18:37:29] <Connor> and how do you know this is low current ?
[18:37:44] <Connor> I see no current info for the motor.. just for the 2 switches..

[18:39:00] <zeeshan> 0.5A
[18:39:10] <Connor> ok
[18:39:51] <zeeshan> okay so im thinking it works like this:
[18:40:11] <zeeshan> fuse holder 0.5A -> L1 -> pin #4
[18:40:18] <zeeshan> in parallel from that same fuse holder
[18:40:38] <zeeshan> -> L1 -> relay contact -> pin 5

[18:41:52] <Connor> NO
[18:42:02] <Connor> not L1 to relay to pin 5
[18:42:09] <Connor> L1 to relay to pin 8
[18:42:13] <Connor> l2 on p5
[18:42:56] <Connor> SL1 will light up when DK is pressed.. or power applied to p8
[18:43:02] <Connor> as well as the motor will turn on.
[18:43:06] * zeeshan thinks about this.
[18:43:26] <Connor> 8 and 4 are parallel to each other..
[18:43:41] <Connor> so, you can't hook one side up to L1 and other the other up to L2 without shorting out.
[18:44:55] <zeeshan> what goes to pin 4then
[18:45:04] <zeeshan> i see the motor working correctly with l1 at pin 8
[18:45:07] <zeeshan> and l2 on p5
[18:45:18] <Connor> L1 ON PIN 4 TOO
[18:45:29] <zeeshan> okay i'm slow
[18:45:30] <zeeshan> i see it now :)
[18:47:08] <zeeshan> its so weird
[18:47:13] <zeeshan> only l1 is being switched
[18:47:21] <jdh> s/its/I\'m/
[18:47:31] <zeeshan> i thought in 240v circuits
[18:47:34] <zeeshan> you had to switch both l1 and l2
[18:47:40] <zeeshan> for safety.
[18:47:49] <Connor> normally you do.
[18:49:16] <Connor> But, since this is all enclosed.. they probably feel that it's safe.
[18:49:25] <jdh> I have a 240vac coil on my compressor contactor. It's creepy working near it since one side is always hot
[18:50:52] <zeeshan> hehe
[18:51:01] <zeeshan> i guess this is why you have lockout procedures
[18:51:39] <Connor> You might be able to use some sort of timed relay in that mix so that you don't have to use linuxcnc logic to handle it..
[18:51:51] <zeeshan> Connor: i'd like to do a couple things
[18:51:57] <zeeshan> i want to ensure machine is on
[18:52:03] <zeeshan> axis are active
[18:52:10] <zeeshan> only then lubrication will be on
[18:52:17] <zeeshan> otherwise it'll sit there wasting oil while the machine is idle

[22:02:29] -!- Deejay has quit [Quit: bye]
[22:11:12] <andypugh> For a really accurate one I would be looking at more than one thermocouple, including one buried in the element to keep that below max service temp.
[22:12:23] <andypugh> The MAX13855 chip connects nicely to the Arduino SPI to measure K-type thermocouples. That would let you control 2 zones and limit element temp too.

[22:20:30] <andypugh> (A MAF sensor _might_ work for water, and the world is full of them)
[22:20:39] <SpeedEvil> I suspect if it's the flow rate I'm thinking of, heater is going to be utterly useless
[22:20:45] <SpeedEvil> unless it's megawatts
[22:20:50] <renesis> speedevil: i dunno, you turn on a regulated tap on a house
[22:20:59] <renesis> thats maybe few gpm?
[22:21:01] <SpeedEvil> oh
[22:21:10] <SpeedEvil> right - I was thinking it was a spraygun
[22:21:26] <SpeedEvil> that's not much flow at all in a 2" pipe
[22:21:28] <andypugh> renesis: The MAF sensors I am familiar with use a heated element, no moving parts.
[22:21:46] <renesis> im hoping maybe a few watts through a precision resistance and a couple of thermocouples
[22:21:52] <SpeedEvil> water has ~4000 times the thermal capacity
[22:21:52] <renesis> andypugh: oh neat
[22:21:56] <zeeshan> maf is meant for air flow
[22:22:07] <renesis> yeah but the air is going much faster
[22:22:14] <renesis> so maybe it works out
[22:22:20] <zeeshan> it works through density change
[22:22:21] <zeeshan> or something
[22:22:22] <zeeshan> i forget
[22:22:24] <SpeedEvil> you need ~20kW to boil a few GPM
[22:22:26] <renesis> but its a start
[22:22:31] <andypugh> zeeshan: I know, but they might work and there are many around to experiment with,
[22:22:33] <SpeedEvil> do you want hot water?
[22:22:40] <zeeshan> why use something not meant for it?
[22:22:40] <renesis> no i dont want hot at all
[22:22:47] <zeeshan> theres plenty of flow measurement devices out there
[22:22:53] <zeeshan> cheap one is a manometer
[22:22:58] <zeeshan> more expensive is a rotameter
[22:23:01] <renesis> you heat a point and measure the temp
[22:23:09] <renesis> and then monitor the temp of another point
[22:23:16] <zeeshan> thats a hot wire maf sensor
[22:23:18] <SpeedEvil> renesis: yes - that relies on heating the fluid
[22:23:18] <renesis> and the delta is related to flow rate
[22:23:24] <renesis> no flow, theyre the same temp
[22:23:38] <SpeedEvil> oh - not quite that
[22:23:41] <SpeedEvil> hmm
[22:23:48] <renesis> speedevil: right so how much heat prob depends on how sensitive the tc measurement
[22:23:54] <zeeshan> you can even use a venturi tube
[22:23:55] <renesis> and how far the tc
[22:24:06] <renesis> and how much heat

[22:38:28] <SpeedEvil> zeeshan: yes - with a venturi - trivially
[22:38:52] <SpeedEvil> I thought the idea was to stay on 2' for some reason
[22:39:11] <renesis> just because its easy to poke shit into the side of a pipe

[22:39:27] <zeeshan> it's not about easy

[22:39:30] <zeeshan> its about "reliable"
[22:39:31] <zeeshan> :P
[22:39:46] <renesis> easy to fab is usually reliable
[22:40:01] <andypugh> You could use a different automotive sensor (because they are cheap commodity parts). Venturi and a delta-pressure sensor from a diesel engine particulate filter.
[22:40:14] <renesis> a heater and two tc is prob going to be more reliable than two pressure sensors
[22:40:28] <renesis> tho thats not a bad alternative
[22:41:07] <renesis> and id rather stay away from off the shelf parts and end product would have lots of parallel channels
[22:41:49] <renesis> a thermocouple amp is a lot easier to multiplex than a pressure sensor
[22:42:03] <renesis> and thermocouple cable is cheap
[22:42:32] <andypugh> (Actually, looking at DPF pressure sensors, it looks like they are only actually cheap to the car makers, £40 on eBay for a part we pay $5 for)
[22:43:02] <renesis> tons of pressure sensors does not seem cheap, tons of valves to multiplex a sensor does not sound cheap, pressure tube lengths affecting measurements does not sound good

[22:48:22] <andypugh> Just spot weld chromel and alumel wires very close together to the same specimen and you get a very fast response.
[22:48:23] <renesis> expensive and slow
[22:48:28] <zeeshan> well it handles
[22:48:30] <zeeshan> 1800F
[22:48:33] <zeeshan> so im happy with it
[22:48:48] <renesis> right if you dont need the temp resistance theyre a waste of money
[22:49:04] <andypugh> I was measuring the quench-rate of steel specimens into a molten salt bath.
[22:49:07] <renesis> you cant get faster than just wires
[22:49:11] <zeeshan> andypugh: nice!@
[22:49:29] <zeeshan> i forgot
[22:49:32] <zeeshan> you're mr materials :)
[22:49:36] <renesis> andypugh: have you tried just spot welding the wires?
[22:49:40] <andypugh> So speed was important, and each thermocouple did one test.
[22:49:51] <renesis> to themselves
[22:50:15] <andypugh> It was a while ago, and I just realsied that I am confusing two things.
[22:50:45] <andypugh> We spot-welded probe wires to samples to measure crack-growth.
[22:50:55] <renesis> so you had suicidal tc probes?
[22:51:44] <andypugh> Thermocouples were welded in an inert atmosphere using a similar sort of set-up then peined into a spark-eroded hole in the sampls.

[22:52:41] -!- chillly has quit [Quit: Ex-Chat]
[22:53:05] <renesis> so you made welded wire probes and then hammered them into a hole
[22:53:09] <andypugh> Yes
[22:53:22] <renesis> neat
[22:53:39] <andypugh> Then heated to 850C and dropped out of the bottom of the tube furnace into molten sodium hydroxide
[22:54:00] <andypugh> Then cut-back the wires, made a new junction, and repeated.
[22:54:18] <renesis> so i was thinking of doing little potted plugs
[22:54:33] <renesis> like, one with a tc, and one with a tc and a heater
[22:55:06] <renesis> and its like, city water temp so nothing has to be special
[22:55:13] <andypugh> I think we used gas and air to weld, but interestingly Alibaba is full of oxy-hydrogen sets for the job:
http://www.alibaba.com/showroom/oxy--hydrogen-thermocouple-welding-machine.html
[22:55:21] <renesis> can maybe just use temp sensor IC, too
[22:55:35] <renesis> i dunno how precise this shit needs to be really
[22:56:55] <renesis> temp sensor ic prob way slower
[22:58:17] <renesis> andypugh: ha neat pic of all the little welded TC ends in that link
[22:59:21] <andypugh> Ah, they really are selling just a little welding torch
[23:00:15] <andypugh> My sister uses exactly that setup for jewellry, the cutest welding torch in the world with hypodermic syringes for nozzles.
[23:00:49] <andypugh> I seem to recall ours were welded inside a glass tube, but it was 25 years ago.

[23:10:15] <zeeshan> i miss hubble
[23:10:54] <zeeshan> i wonder how good james webb space telescope will be
[23:12:16] <andypugh> It should be better

[23:13:21] <zeeshan> so sexy
[23:13:30] <ssi> and then build a fixture to start doing these enclosures
[23:14:00] <zeeshan> i wonder how long those mirrors took
[23:14:06] <zeeshan> to make :P
[23:14:25] <ssi> incorrectly
[23:14:26] <ssi> hahaha
[23:14:30] <zeeshan> how in the world do you clean a mirror like that

[23:40:13] <zeeshan> without a wiring diagram
[23:40:15] <zeeshan> this has been a nightmare
[23:40:22] <zeeshan> now im looking at the speed selector stuff
[23:40:29] <zeeshan> it makes NO sense

[23:41:10] <zeeshan> how is one supposed to know how this circuit board works!!!
[23:41:13] <zeeshan> without a diagram :{
[23:41:33] <XXCoder> wow gonna love ye olde circuit boards
[23:41:50] <andypugh> zeeshan: They don’t want _you_ to know, they want you to pay them for knowing.
[23:41:58] <XXCoder> looked up serial #?
[23:42:28] <zeeshan> yea i looked up "indelco ag 801 531-1"
[23:42:47] <zeeshan> andypugh: well shit, i need a wiring diagram to hook the pinouts
[23:42:51] <zeeshan> i dont care how the board works :P
[23:42:58] <zeeshan> just need to know what terminals those wires need
[23:44:52] -!- Miner_48er has quit [Quit: Leaving]
[23:44:53] <andypugh> You can often find things out about a board from the RF testing code. (I have forgotten the acronym)
[23:45:31] <andypugh> There is a database that will tell you who certified the board, and that tells you the real manufacturer
[23:46:00] <zeeshan> i dont see any numbers on it
[23:46:03] <zeeshan> other than what isee in that pic
[23:48:59] <andypugh> That looks like an intereting board. Presumably the layout is delibrate. Is it extremely high voltage?
[23:49:35] <zeeshan> no
[23:49:42] <zeeshan> its a 24V board i'm assuming.
[23:50:04] <zeeshan> it has something to do with the motors
[23:50:13] <zeeshan> that shift the gears for the transmission
[23:50:16] <renesis> prob hall sensors?
[23:50:21] <zeeshan> youre right
[23:50:31] <zeeshan> the ugs-3020t is the only thing i can find details on
[23:50:37] <zeeshan> and it comes up as "magnetically activated switches"
[23:50:41] <renesis> nice bushings for a PCB, heh
[23:50:54] <andypugh> There has to be a reason for the layout?
[23:51:19] <zeeshan> "these devices are magnetically activated electronic switches utilizing hall effect for sensing magnetic field. each circuit consists of a silicon hall generator, amplifier, trigger and output stage integrated with its own voltage regulator onto a monolitihc silicon chip"
[23:51:34] <zeeshan> "circuit outputs can be directly interfaced with a bipolar or MOS logic circuits"
[23:51:36] <renesis> that sounds like amplified and schmitt trigger hall sensor
[23:51:42] <zeeshan> the pinouts i see are vcc, gnd and vout
[23:51:45] <renesis> yeah what the datasheet says
[23:52:06] <zeeshan> so let me get this straight
[23:52:18] <renesis> ive played with sot23 sensors like that
[23:52:20] <zeeshan> these sensors are picking up the magnetic fields from the motors that mount to this circuit?
[23:52:21] <zeeshan> ?!?
[23:52:22] <andypugh> Does that board bolt to the back of three motors?
[23:52:27] <zeeshan> yes
[23:52:30] <renesis> yeah
[23:52:39] <andypugh> I wonder why?
[23:52:43] <zeeshan> https://www.flickr.com/photos/128539016@N05/15536981611/
[23:52:48] <zeeshan> thats how its assembled
[23:52:55] <renesis> thats why i said hall sensors, theyre positioned like for pole detection on a motor
[23:52:55] <andypugh> There are not enough sensors for a brushless motor
[23:53:06] <zeeshan> maybe they pick up the teeth?
[23:53:11] <zeeshan> on the gears electors?
[23:53:20] <zeeshan> wait theres a weird rod on it.

[23:54:00] <renesis> shrug, ive seen two and three sensor setups
[23:54:09] <renesis> and hall sensors with optical sensors
[23:54:15] <zeeshan> this nonsense is the last thing ineed to figur eout
[23:54:18] <zeeshan> andf i can start wiring stuff up
[23:54:22] <_methods> wow i swear to god i just heard on the news they want to build a moat around the white house
[23:54:31] <andypugh> Ah, yes, each actuator has two positions for gear selection and the magnets/sensors tell the system when to stop the motor.
[23:54:40] <renesis> meryan00: to keep the what out?
[23:54:46] <renesis> _methods: ^
[23:54:59] <_methods> i guess the fences aren't workig lol
[23:55:03] <zeeshan> https://www.flickr.com/photos/128539016@N05/15806560136/
[23:55:04] <_methods> so now they want to build a moat
[23:55:08] <zeeshan> this is what the motors look like on the other side
[23:55:18] <_methods> they need to do that shit minecraft style and fill it with lava
[23:55:40] <renesis> is that rod magnetized?
[23:55:41] <renesis> wtf
[23:55:46] <zeeshan> it must be
[23:55:50] <zeeshan> thats the only thing that would make sense
[23:56:30] <andypugh> it seems like it might be quite simple. Three two-position levers for 8 gears, the system chooses a gear, and moves each motor to the right position, sensed by the 6 sensors.
[23:56:35] <zeeshan> https://www.flickr.com/photos/128539016@N05/14926219104/in/photostream/lightbox/
[23:56:49] <zeeshan> the rod goes through and attaches inside those splined teeth
[23:57:19] <andypugh> There is a magent on each internal-toothed gear
[23:57:51] <andypugh> ( I can see them)
[23:58:18] <zeeshan> in the last pic i posted?
[23:58:22] <andypugh> Yes
[23:58:35] <zeeshan> how do you zoom in in flickr
[23:58:38] * zeeshan doesnt know
[23:59:18] <andypugh> The phasing of the outer gear and magnet to the inner gear is likely to be critical, don’t disturn it without making reference marks and photos
