[00:54:45] <zeeshan> quiet in here tonight
[00:54:50] <zeeshan> where is everyone =[
[01:44:00] <zeeshan> https://www.flickr.com/photos/128539016@N05/15067408304/
[01:44:08] <zeeshan> left line comes from hydraulic pump
[01:44:14] <zeeshan> right goes to drawbar
[01:44:22] <zeeshan> im trying to figure out what the fitting into the machine goes to!
[01:53:38] <archivist> whatever the manual says :)
[01:54:34] <archivist> poke a camera in a hole
[02:16:05] <Connor> zeeshan: Does that machine have glass scales ?
[02:16:12] <zeeshan> yes
[02:16:15] <zeeshan> archivist: no manuals
[02:16:38] <Connor> Your going to need a additional encoder board then.
[02:18:01] <Deejay> moin
[02:18:19] <Connor> Something like the 7I85
[02:18:34] <zeeshan> why
[02:18:45] <Connor> So you can use the scales.
[02:18:49] <zeeshan> nah
[02:18:51] <zeeshan> i got interpolator boards
[02:18:54] <zeeshan> which output ttl
[02:18:57] <zeeshan> 5v ttl
[02:19:08] <Connor> huh ?
[02:19:27] <zeeshan> 7i77 has ttl inputs for encoders
[02:19:40] <Connor> Yes. But those will be used by the servo's
[02:19:50] <zeeshan> these are perm mag servos
[02:19:57] <zeeshan> they have tachometers
[02:20:00] <zeeshan> which feedback to the servo drive
[02:20:02] <zeeshan> not mesa
[02:20:12] <Connor> okay. Do they not have encoders on them ?
[02:20:21] <zeeshan> yes, no encoders
[02:20:32] <zeeshan> they dont need encoders since it's got glass scales
[02:20:36] <zeeshan> which is used for position feedback
[02:20:54] <Connor> some I've seen have both encoders on servo's plus glass scales.
[02:20:59] <zeeshan> help me figure out why hydraulic line goes into machines :-(
[02:21:10] <zeeshan> Connor: ahh
[02:21:24] <Connor> uses the encoders for velocity information..
[02:21:35] <zeeshan> yea that'll usually get fed int opthe servo drive
[02:21:42] <zeeshan> from what ive been seeing at least w/ the amc drives
[02:21:54] <Connor> yes, but also feeds into linuxcnc too.
[02:21:59] <zeeshan> why
[02:22:07] <Connor> No idea.
[02:22:20] <zeeshan> i think you feed it to linuxcnc if you want it to do the velocity feedback too
[02:22:22] <Connor> Pete's feeds into his driver and from driver into mesa.
[02:22:32] <zeeshan> hm
[02:22:33] <Connor> but, he doesn't have glass scales.
[02:22:46] <zeeshan> im really happy this thing has glass scales
[02:22:56] <zeeshan> none of this backlash nonsense trying to throw things off
[02:22:56] <Connor> AND his can be setup to be used step/dir
[02:23:32] <Connor> anyway.. on hydraulics.. maybe a pressure valve, or perhaps a gauge.?
[02:24:04] <zeeshan> honestly it goes int othe machine
[02:24:06] <zeeshan> and dissapears
[02:24:07] <zeeshan> lol
[02:24:14] <Connor> what kind of machine is this again ?
[02:24:20] <zeeshan> mikron wf21c
[02:24:20] <Connor> model # ?
[02:24:43] <zeeshan> maybe it uses hydraulics for the Z axis knee?
[02:24:53] <Connor> Possibly.
[02:24:56] <zeeshan> like as a counter thingy
[02:25:08] <Connor> Which means that pump probably runs all the time.
[02:25:20] <zeeshan> https://www.flickr.com/photos/128539016@N05/15648007556/
[02:25:24] <zeeshan> unfortunately the tag is like that
[02:25:39] <Connor> Hydraulic work-piece clamping 
[02:25:42] <Connor> possibly ?
[02:25:56] <Connor> http://www.mtionline.com/machine-marketplace/metal-cutting/milling/milling-general/ml-297749-mikron-wf-21-c.html#.VFXl2mCx3UY
[02:26:25] <zeeshan> hmm
[02:26:46] <Connor> It have any auxiliary connections near or on the table ?
[02:26:54] <zeeshan> not that are too aparent to me
[02:29:53] <Connor> That's about the only thing I can think of.
[02:30:09] <Connor> is some sort of auxiliary use such as clamping.
[02:30:11] <zeeshan> yea i think youre right
[02:30:16] <zeeshan> im just wondering why it goes into the machine
[02:30:28] <zeeshan> like thats a pretty solid chunk of steel its going into
[02:30:34] <Connor> probably has a port somewhere.
[02:30:38] <Connor> your not seeing.
[02:31:27] <zeeshan> i tested out my coolant pump too today
[02:31:33] <zeeshan> works :D
[02:31:47] <zeeshan> not as emotional as the hydraulic pump
[02:35:08] <zeeshan> http://www.ebay.ca/itm/SHARS-HIGH-QUALITY-CAT40-MAKINO-COOLANT-THRU-PULL-STUD-RETENTION-KNOB-/330879314083?pt=BI_Tool_Work_Holding&hash=item4d09f1a8a3
[02:35:16] <zeeshan> is this coming up as $310 usd?
[02:35:24] <Connor> yes
[02:35:27] <zeeshan> sigh
[02:35:36] <Connor> COOLANT THRU
[02:35:48] <Connor> you don't need a THRU COOLANT pull stud do you ?
[02:35:52] <zeeshan> nah
[02:35:54] <zeeshan> but its cheap :P
[02:36:02] <archivist> you have a cnc lathe, make them
[02:36:11] <Connor> for a single stud ?
[02:36:20] <Connor> that's cheap ?
[02:36:29] <zeeshan> yea theyre heat treated i think
[02:36:41] <zeeshan> er.. sorry you donts ee the actual price
[02:36:43] <zeeshan> its $10
[02:36:43] <Connor> I think your machine is ISO40
[02:36:51] <zeeshan> yea its iso40 din2080
[02:36:59] <zeeshan> but if i wanna use bt40 or cat40 hjolders
[02:37:09] <zeeshan> i need to buy the appropriate din2080 conversion pull stud
[02:37:13] <Connor> where do you see $10 ??
[02:37:21] <zeeshan> in their catalog
[02:37:28] <Connor> it's showing $310.95 and $350.58 C
[02:37:36] <zeeshan> yea i checked their catalog
[02:37:40] <Connor> strange.
[02:37:41] <zeeshan> its a mistake
[02:38:06] <Connor> What's wrong with ISO40 ?
[02:38:22] <Connor> and.. how can you do bt40 or cat40 holders ?
[02:38:35] <zeeshan> iso40 isnt as common
[02:38:39] <zeeshan> most modern tooling is cat40
[02:38:40] <zeeshan> or bt40
[02:38:52] <zeeshan> what do you mean how
[02:38:54] <Connor> not tooling.. tool holders..
[02:39:03] <zeeshan> you know what imean.
[02:39:11] <Connor> You would not have to change the taper or something ?
[02:39:15] <zeeshan> no
[02:39:17] <zeeshan> theyre all #40 taper
[02:39:20] <Connor> or is it just a differences in the pull stud ?
[02:39:28] <zeeshan> the difference is in the length of the taper
[02:39:36] <zeeshan> and the pull stud
[02:39:43] <zeeshan> cat40 and bt40 are shorter than iso40
[02:39:47] <zeeshan> so this allows you to run a pull stud
[02:40:04] <zeeshan> rather than buying expensive iso40 din2080 tool holders
[02:40:07] <Connor> How is it gripping now? Does ISO40 not have a pullstud too ?
[02:40:15] <zeeshan> iso40 doesnt
[02:40:19] <zeeshan> but iso40 din2080 does
[02:40:31] <zeeshan> it's gripping on the cylinder
[02:40:36] <zeeshan> so not on the correct portion :P
[02:40:43] <zeeshan> i can wobble the tool holder
[02:40:57] <Connor> so, you need a pull stud.
[02:41:01] <zeeshan> yes
[02:41:03] <zeeshan> and new tool holder
[02:41:08] <zeeshan> that dont have cylinders on em
[02:41:10] <Connor> what tool holder is that you have ?
[02:41:15] <zeeshan> iso40
[02:41:22] <Connor> picture of it ?
[02:41:39] <zeeshan> sorry its not iso40.
[02:41:41] <zeeshan> its nmtb40
[02:42:12] <zeeshan> https://www.flickr.com/photos/128539016@N05/15616955925/
[02:42:35] <Connor> So the pull stud clamp is clamping the straight part?
[02:42:40] <zeeshan> haha yea
[02:42:44] <Connor> That's not good.
[02:43:27] <Connor> the iso40 din2080 has a grove in it..
[02:43:37] <Connor> can you convert easy enough ?
[02:44:01] <Connor> Change out the clamp and longer draw bar ?
[02:44:24] <zeeshan> its easier to use the correct tool holder
[02:44:24] <zeeshan> http://www.maritool.com/images/CAT40-FLOATING-TAP-TOOL-HOLDER-TER16-1.jpg
[02:44:27] <zeeshan> im gonna buy something like that
[02:44:31] <zeeshan> and that shars pull stud
[02:44:35] <zeeshan> and it should be the correct length
[02:45:42] <Connor> okay. So, putting a different pull stud on it lets it work with different 40 tapers I guess.. I don't know much about the higher end stuff.
[02:45:49] <Connor> Just R8, MT sizes
[02:46:22] <zeeshan> its anightmare
[02:46:24] <zeeshan> ill tell you that
[02:46:27] <zeeshan> its a huge learning curve
[02:46:32] <zeeshan> its like inserts when you first see em
[02:46:33] <zeeshan> theyre so confusing
[02:47:36] <Connor> Wow. Past bed time.
[02:47:59] <Connor> off to bed.
[02:48:01] <Connor> have fun
[02:49:26] <zeeshan> cya
[04:36:38] <renesis> guys
[04:36:59] <renesis> Haas + Ferrari 2015 F1 team
[04:37:03] <renesis> discuss
[04:42:45] <yeahiiii> hey there, I just tried to install linuxcnc 2.6 (the wheezy hybrid iso) on 2 different machines (atom 330, core i3 haswell). both systems were limited to a single core, hyperthreading turned off but get a max jitter around 50000 on BOTH systems. any idea what could be wrong with my setup?
[04:44:11] <yeahiiii> (the max jitter is ~10000, but running glxgears lets it jump to 50000)
[06:17:26] <mk0> hello guys. i'd like to make one more machine and would like to reduce the size of the PC and its price. is beagle bone black + romanian parport suitable variant?
[06:22:05] <mk0> ouch, usa is sleeping...
[06:24:12] <SpeedEvil> The BBB has a port which uses the PRUs on it. This is reportedly great.
[06:24:20] <SpeedEvil> However, graphical performance is amajor issue
[06:24:47] <SpeedEvil> Cheap low-power PC boards start at not that much more than the BBB
[06:32:38] <mk0> and size?
[06:32:44] <Tom_itx> has anyone made a list of suitable ones yet?
[06:33:25] <mk0> i was advised atom d525, but it's so outdated that it's hard to buy
[06:33:29] <mk0> to find
[06:33:39] <Tom_itx> i know CaptHindsight has posted links to several
[06:34:07] <Tom_itx> yeah it works great but is hard to find
[06:34:34] <mk0> maybe something more modern and well-known?
[06:38:24] <SpeedEvil> http://www.ebuyer.com/630828-gigabyte-ga-j1900n-d3v-intel-celeron-j1900-2ghz-vga-dvi-hd-audio-mini-itx-ga-j1900n-d3v say
[06:39:41] * Jymmm is not a gigabyte fan
[06:39:59] <SpeedEvil> http://www.ebuyer.com/630832-gigabyte-ga-j1800n-d2h-intel-celeron-j1800-2-41ghz-vga-hdmi-hd-audio-mini-itx-motherboard-ga-j1800n-d2h I meant
[06:40:33] * Jymmm is STILL not a gigabyte fan =)
[06:40:53] <SpeedEvil> yes - but it's cheaper!
[06:40:55] <SpeedEvil> :)
[06:41:25] <Jymmm> Gb engineers tend to make their boards "poofy"
[06:41:36] <SpeedEvil> - I'mnot especially recommending it - just that I was looking for other reasons, and noticed that it had a PP
[06:41:37] <SpeedEvil> ?
[06:42:29] <Jymmm> They tossis everthing imaginable accessory wise; making them less performance and more prone to "issues"
[06:44:33] <Jymmm> Like what mini board needs a "1 x chassis intrusion header", that's usually for servers.
[06:44:58] <Jymmm> and still maintainging PS2 ports
[06:45:43] <Jymmm> Heh, not even sure if you can still buy PS/2 kybd/mice these days =)
[06:46:05] * SpeedEvil bought 3 ps/2 keyboards a couple of years ago
[06:46:14] <Jymmm> why?
[06:46:16] <SpeedEvil> IBM trackpoint space-saver ones
[06:46:33] <Jymmm> ah
[06:46:45] <SpeedEvil> http://thumbs2.ebaystatic.com/d/l225/m/mRtXDMp_vYGbYJS4Bp4KUrw.jpg
[06:46:49] <SpeedEvil> But with big enter
[06:46:58] <SpeedEvil> It's ideal for use in bed under the covers, when it's cold
[06:47:07] <Jymmm> hahaha
[06:47:46] <Jymmm> Um, I can think of other things to do when in bed. N kybd required
[06:47:51] <Jymmm> no*
[06:49:08] <Jymmm> reviews are a tad low http://www.newegg.com/Product/Product.aspx?Item=N82E16813128688
[06:50:06] <SpeedEvil> Jymmm: yes - but those are more expensive to purchase than keyboards
[06:50:31] <Jymmm> huh?
[06:52:06] <SpeedEvil> 'Um, I can think of other things to do when in bed. N kybd required
[06:52:24] <Jymmm> NO kybd required
[06:57:19] <mk0> i do not see lpt there.
[06:57:21] <SpeedEvil> well, yes
[06:57:27] <SpeedEvil> mk0: it's not a port, but a header
[06:57:37] <mk0> f
[06:57:41] <mk0> ah
[07:12:38] <Jymmm> Just watched a Jackie Chan movie (1994), the outakes in the credits had him crawling thru a huge bed of coals FOR REAL. Daaaaaaaaaaaaamn!
[07:13:07] <Jymmm> good movie too btw =)
[07:13:22] <Jymmm> http://www.imdb.com/title/tt0111512/
[08:01:50] <PetefromTn_> Morning folks!
[08:02:08] <SpeedEvil> PetefromTn_: Afternoon
[08:02:18] <PetefromTn_> LOL
[08:02:26] <PetefromTn_> whatsgoinon?
[08:02:44] <PetefromTn_> anything interesting in the world of LinuxCNC today?
[08:03:28] <SpeedEvil> I am currently crawling under a 100kg sheet of plywood, propped 40cm off the ground, to install insulation under the floor of my shed.
[08:03:29] <PetefromTn_> I just heard from one of my customers this morning
[08:03:50] <SpeedEvil> This is sort-of-related inthat I am going to be using said shed to try to get some CNC preparationsdone
[08:03:52] <PetefromTn_> oh that does not sound like fun
[08:04:02] <PetefromTn_> well thats good.
[08:04:04] <SpeedEvil> A 1/4 scale full-sheet router, probably
[08:04:12] <PetefromTn_> sweet
[08:04:16] <SpeedEvil> err - 1/2
[08:04:26] <SpeedEvil> That is - 1.2*0.6m bed.
[08:04:30] <SpeedEvil> (plus a bit)
[08:04:47] <PetefromTn_> this customer was the first one to receive my prototype Short Steyr Rail I designed
[08:05:20] <ssi> morn
[08:05:22] <SpeedEvil> :)
[08:05:27] <PetefromTn_> he sent me some nice photos of the rail mounted on the new rifle setup with his gorgeous scope
[08:05:31] <PetefromTn_> Morn SSI
[08:05:47] <PetefromTn_> http://i.imgur.com/6TCytja.jpg
[08:06:05] <ssi> looks great
[08:06:10] <PetefromTn_> http://i.imgur.com/1Gda44T.jpg
[08:06:30] <PetefromTn_> http://i.imgur.com/qfTQ28R.jpg
[08:06:43] <syyl_> that looks neat!
[08:06:53] <PetefromTn_> Thanks man
[08:07:02] <PetefromTn_> I thought it complimented the rifles lines nicely
[08:07:26] <SpeedEvil> Looks good
[08:07:34] <syyl_> the whole thing looks nice :o
[08:07:48] <PetefromTn_> yeah that is a sick air rifle I would love to have one..
[08:08:29] <PetefromTn_> That damn scope alone costs like almost $4k
[08:16:30] <ssi> more moving today :(
[08:16:32] <ssi> hate that game
[08:16:48] <PetefromTn_> Good luck man
[08:16:57] <PetefromTn_> We were supposed to show our house this morning
[08:17:06] <PetefromTn_> but so far have not heard from the people
[08:17:17] <PetefromTn_> probably another no show
[08:17:18] <ssi> :/
[08:17:35] <PetefromTn_> Oh well I love cleaning the piss out of my house and mowing the lawn anyways.. hehe
[08:17:57] <ssi> heheh
[08:18:38] <ssi> to move the machines, I called the guy that rented me that 12k hyster lift couple weeks ago that I used to unload the VMC
[08:19:12] <ssi> he charged me $1k for a one day lift rental down here, and two 130 mile round trips, one to fetch the machines and one to fetch the forklift
[08:19:17] <ssi> and he helped me fix my forklift :D
[08:19:20] <ssi> it runs SOOOOO GOOOD now
[08:19:40] <PetefromTn_> wow that is a lot of money but not bad really for all that moving.
[08:19:42] <CaptHindsight> mk0: we have been using just about anything AMD mini-itx or micro-atx for the past few years, only some Biostar have board had issues with BIOS and Linux in general
[08:19:45] <ssi> really not that bad
[08:19:51] <ssi> $250 for the lift rental and $3/mile
[08:19:53] <PetefromTn_> glad to hear your fork truck is working well.
[08:19:55] <ssi> he didn't even charge for the lift delivery
[08:20:12] <PetefromTn_> nice
[08:20:12] <ssi> and it was a full day's job for him because of traffic
[08:20:24] <ssi> plus insurance will pay it :P
[08:20:26] <PetefromTn_> yeah traffic in Atlanta SUX!!
[08:20:31] <ssi> heh yeah
[08:20:35] <ssi> especially on fridays
[08:20:41] <ssi> and fridays which happen to be halloween
[08:20:50] <ssi> and fridays which happen to be halloween when bill clinton is in tow n:(
[08:21:11] <PetefromTn_> jeez..
[08:22:36] <ssi> the view from here
[08:22:37] <ssi> https://pbs.twimg.com/media/B1cQ45XIcAAzlfo.jpg:large
[08:23:01] <PetefromTn_> is that the apartment you are living in?
[08:23:05] <ssi> yeah
[08:23:09] <PetefromTn_> nice
[08:23:21] <PetefromTn_> how far is it from your hangar?
[08:23:30] <ssi> my hangar is on the left
[08:23:41] <ssi> what you can see is B row on the left and C row on the right
[08:23:45] <ssi> A row is the backside of B
[08:23:51] <ssi> and mine are the closest three
[08:23:58] <ssi> so it's about 80' from where I'm sitting
[08:24:04] <PetefromTn_> maybe you should just buy that apartment and live there and that way you are right near your machines and planes and whatnot LOL
[08:24:09] <ssi> maybe 120' :)
[08:24:18] <ssi> this apartment isn't for sale :P
[08:24:22] <ssi> it's part of another much bigger hangar
[08:24:28] <PetefromTn_> EVERYTHING is for sale LOL
[08:24:35] <ssi> this building is 120x140', has offices on the lower level below this apartment
[08:24:45] <ssi> the apartment is 120x30', upstairs
[08:25:09] <PetefromTn_> I swear you would almost not recognize my shop now man heh
[08:25:39] <ssi> https://pbs.twimg.com/media/B1cRpgKIYAARHNy.jpg:large
[08:25:46] <ssi> window on the other side of the living room looks into the hangar
[08:25:58] <PetefromTn_> all the toys!!
[08:26:01] <ssi> yep!
[08:26:04] <ssi> I want a building exactly like this
[08:26:15] <ssi> if I can swing it, I'm going to try to get a county land lease here or at another airport
[08:26:19] <ssi> and build this building
[08:26:21] <ssi> apartment and all
[08:26:25] <ssi> that'll be perfect for me
[08:27:12] <PetefromTn_> I have seen stories of people who have wood or metal shops that buy old commercial buildings and rebuild them to have living spaces above a huge shop.
[08:27:17] <PetefromTn_> That would be awesome
[08:27:19] <ssi> yep
[08:27:23] <PetefromTn_> some are quite elegant
[08:27:34] <ssi> and to have that on an airport would be 100% ideal for me
[08:28:01] <PetefromTn_> then all you need is the airport to be right on the water so you can have your sailboat docked nearby!!
[08:28:16] <ssi> hahaha yes
[08:28:16] <PetefromTn_> :D
[08:29:53] <ssi> I'm contemplating building a mezzanine in the hangar with the machines
[08:30:02] <ssi> but dan had a good point: in the summer it's gonna be 110F up there
[08:30:41] <PetefromTn_> http://i.imgur.com/WTzewrL.jpg http://i.imgur.com/tpETQzL.jpg some more photos he just sent
[08:31:11] <PetefromTn_> that is the Steyr Rifle alongside the Feinwerkbau rifle both of which wear several of the parts I make
[08:31:45] <ssi> awesome
[08:32:09] <ssi> https://pbs.twimg.com/media/B1cTIAWIEAAISTU.jpg:large
[08:32:13] <ssi> I built that one for dan
[08:32:30] <ssi> similar to my big build but shorter, lighter barrel, 308 instead of 30-06
[08:32:34] <ssi> and he has a nicer scope
[08:33:01] <PetefromTn_> is that a 700?
[08:33:02] <ssi> mines' a leupold vx3 8.5-25 varmint, his is a leupold mk4 8-24 mildot
[08:33:03] <ssi> yeah
[08:33:31] <PetefromTn_> Leupy's are good scopes well made
[08:33:37] <ssi> yes, they're excellent
[08:33:40] <ssi> best value in scopes I think
[08:33:48] <ssi> you can get better glass but the price goes up dramatically
[08:33:56] <PetefromTn_> yeah it sure as hell does
[08:33:56] <ssi> plus I can get dealer pricing on them through a friend
[08:34:40] <PetefromTn_> they have some new ones out with oval lenses or something that are supposed to be very nice and also some really wide body ones for more light transmission.
[08:34:42] <ssi> I think we paid $700 for my vx3 and $1000 for dan's mk4
[08:35:09] <PetefromTn_> Several of the guys that shoot Field Target Competition use the Leupold Comp scopes
[08:38:13] <PetefromTn_> http://i.imgur.com/5Tx2RW9.jpg That is a custom splash anodized Leupold Competition scope I machined a sidewheel for a customer about two years ago.
[08:38:48] <ssi> neat
[08:40:03] <PetefromTn_> http://i.imgur.com/YYFWFfw.jpg That's it on his Daystate custom rifle
[08:40:39] <ssi> wow that stock is crazy
[08:40:47] <ssi> MEGAMANNLICHER
[08:40:55] <PetefromTn_> yeah I love the heavy wood stocks used in FT
[08:41:06] <PetefromTn_> they are really beautiful
[08:44:45] <SolarNRG> hi guys, has anybody in here ever messed about with pressure cookers before?
[08:45:00] <ssi> oh boy I remember you
[08:45:09] <SolarNRG> hi ssi, how's it going?
[08:45:10] <ssi> :)
[08:45:14] <ssi> up and down
[08:45:21] <PetefromTn_> good remember or bad remember LOL
[08:45:36] <ssi> something about crazy ass experiments
[08:45:42] <ssi> can't recall what exactly
[08:45:46] <ssi> casting seems to stick in my mind
[08:45:48] <SolarNRG> listen I've made myself a makeshift distillery out of a pressure cooker, some stainless pipe kapton tape and a metal coat hanger
[08:46:33] <PetefromTn_> isn't that bootleggin'?
[08:46:39] <ssi> PetefromTn_: only under our stupid laws
[08:46:44] <ssi> he's uk if memory serves
[08:46:50] <SolarNRG> anyway, I tried distilling with copper pipe last week and I got a ppm of 037 now with the stainless pipe I get 026ppm from the distilled water can anyone explain why the stainless is better than the copper and how I can further reduce the ppm?
[08:46:50] <PetefromTn_> oh nevermind
[08:47:11] <ssi> SolarNRG: just distilling water?
[08:47:23] <PetefromTn_> is there not a make your own booze irc somewhere?
[08:47:25] <SolarNRG> yeah, trying it out on tap before working on seawater
[08:47:35] <ssi> probably more oxides and impurities in the copper than there are in te ss
[08:47:44] <ssi> so you're leaching more into the condensate
[08:47:46] <SolarNRG> right ok so I'm on the right lines with the stainless
[08:48:28] <SolarNRG> the dude who sold it to me said it wasn't the same grade of stainless as catering grade, I knwo the pressure cooker is 18/10 chrom/nickel and I found some welding rods 18/8 + 2 molyb
[08:48:30] <ssi> I suppose! I don't know much about water purification
[08:48:45] <ssi> what's the coat hangar for? a nucleation site to start condensation?
[08:48:46] <SolarNRG> I wanted to weld the pipe on but two problems: first I'm using 3 differend metals
[08:48:48] <ssi> like a drip rod?
[08:49:13] <pcw_home> also the exact design of the SS vs Cu condensor may be different so different amount of spray
[08:49:20] <SolarNRG> 2nd problem ifI weld the pipe on I cand get the plastic handle back on because I'll either melt it with the welder or I can't bend it round the pipe to fit back on again
[08:49:50] <ssi> if you're good at welding you can do it without heating the whole part up enough to melt the handle
[08:49:56] <SolarNRG> the coat hanger was just so I could hand this zig zag of 2m stainless pipe over the extractor in my kitchen so I could hang the thing up so the water would drip drip drip into the jug
[08:49:56] <ssi> those pots get very hot in use
[08:50:02] <ssi> so the plastic is probably thermoset and can take some heat
[08:50:32] <SolarNRG> not sure but when I milled a 12mm hole out of the plastic handle (not the lid_ it turned to like a really dark greeny brown dust
[08:51:08] <SolarNRG> that was just so I could stick the 12mm stainless pipe into the handle and use the primary valve to vent steam into the pipe which I'm using like a crude reflux condenser
[08:51:33] <SolarNRG> yeah like a drip rod
[08:53:45] <SolarNRG> Point is I've managed to reduce the ppm loads and loads but I want to make it go even lower, I used to have a plug in all in one distillery that worked great for 2 years, got like 500ppm down to 001ppm but it died on me, shortly before I was noticing this yellow substance (sulphur???) in the distillery, thermostat packed in. I also noticed my old distillery had a (carbon filter), I tried to
[08:53:45] <SolarNRG> make one out of epoxy and charcoal but that only made the ppm go up not down, can someone explain to me how carbon filters work, how to make an effective one and what I'll need?
[08:54:55] <SolarNRG> If I sent u guys a pic would that help?
[08:55:22] <ssi> honestly I don't know much about this stuff :)
[08:55:42] <SolarNRG> do u know anything about welding different grades of stainless steel together?
[08:57:10] <SolarNRG> I've welding mild steel pipe before but I've never touched stainless before I got 10 rods at 54 cents each
[08:59:41] <SolarNRG> the stainless rods I got have are 18 chromium 8 nickel 2 molybdynium
[08:59:48] <SolarNRG> if I spelled that right
[09:03:50] <mk0> CaptHindsight, i actually use biostar now :)
[09:04:05] <CaptHindsight> mk0: lucky you!
[09:04:56] <CaptHindsight> mk0: it's not all Biostar, it's just the brand we have had actual problems with
[09:05:10] <mk0> uhu, roulette
[09:07:21] <pcw_home> http://www.newegg.com/Product/Product.aspx?Item=N82E16813138412
[09:07:23] <pcw_home> works well with linuxcnc
[09:08:08] <CaptHindsight> SolarNRG: http://en.wikipedia.org/wiki/Activated_carbon
[09:09:10] <CaptHindsight> SolarNRG: are you distilling salt water or ethanol?
[09:09:29] <pcw_home> The J1800/J1900 MBs also work well but the stock RTAI kernel supplied with Wheezy doent work with their USB port (this has been fixed but the stock kernel has not been updated yet)
[09:09:58] <Jymmm> PCW: WOW it supports 16GB ram too.
[09:13:21] <pcw_home> (not that theres much advantage to > 2G or so for Linuxcnc)
[09:14:18] <Jymmm> PCW: More ram is always a good thing.
[09:14:30] <PetefromTn_> Sweet so this is a proven board to work well with linuxCNC for a good price
[09:14:34] <CaptHindsight> we only use more than 2 of 4GB of ram when Linuxcnc and machine vision are on the same PC
[09:14:42] <CaptHindsight> of/or
[09:14:43] <PetefromTn_> I am gonna be needing something like that for the new CNC lathe build here soon.
[09:15:53] <Jymmm> Also, you may repurpose the mobo in the future and having hte option for more ram leaves you options instead of restrictions.
[09:16:52] <PetefromTn_> Does this one work well with say another 5i25/7i77 combo?
[09:18:02] <pcw_home> It would a 6I25 because it has no PCI slot
[09:20:39] <Jymmm> crap, 1lb propane tank has condensation - "it didn't last night" lol, bastard
[09:21:01] <PetefromTn_> Huh okay what would you recommend for a new MB that has PCI to work with my 5i25 card?
[09:21:05] <pcw_home> http://www.newegg.com/Product/Product.aspx?Item=N82E16813132104&cm_re=asus_j1800-_-13-132-104-_-Product
[09:21:07] <pcw_home> shoud be decent after the RTAI kernel gets fixed (or you could run Preemt-RT)
[09:21:50] <CaptHindsight> RTAI is already fixed, we just need someone with the magic touch to make the debs
[09:24:59] <pcw_home> if you dont need fanless/minitx, this and a G3258 is a very snappy low cost low latency system:
[09:25:01] <pcw_home> http://www.newegg.com/Product/Product.aspx?Item=N82E16813157512&cm_re=asrock_lga1150-_-13-157-512-_-Product
[09:35:04] <PetefromTn_> interesting.
[09:46:42] <pcw_home> But in general other than the soon to be fixed USB issue the J1800 MBs are quite nice: fanless and quite a bit faster than the D525s
[09:47:56] <CaptHindsight> but unfortunately still Intel :p
[09:49:02] <pcw_home> unfortunately lower power and faster than anything AMD has
[09:49:27] <CaptHindsight> yeah, too nad
[09:49:36] <CaptHindsight> nad/bad
[09:50:43] <pcw_home> I wish there was a comparable AMD chip
[09:51:23] <CaptHindsight> we use AMD without issues, what problems do you have?
[09:51:57] <pcw_home> Just hot vs performance
[09:52:49] <CaptHindsight> we never have any thermal issues even with ambient temps to 50C
[09:54:10] <pcw_home> Yeah but if you want fanless and good performance intel is ahead
[09:55:27] <CaptHindsight> I'd rather invest in aluminum that Intel
[09:55:59] <SolarNRG> sorry I was out at the shop, capthindsiht I want to distill salt water but at the moment I'm using tap
[09:56:05] <Tom_itx> aluminum is recycleable
[09:56:07] <Tom_itx> :)
[09:56:21] <SolarNRG> btw capthindsight, did u get ur name from south park coon and friends?
[09:56:49] <CaptHindsight> SolarNRG: 500ppm is still considered fresh water
[09:57:52] <SolarNRG> right ok, some people might consider it to be fresh water, but entertain me as I'm an anti-sodium fluoride cynic who wants all the toxins out of his water, what's the best way of making a carbon filteR?
[09:57:54] <CaptHindsight> what was your 001ppm unit made from?
[09:58:13] <SolarNRG> this electric all in one distillery unit I got for 140 quid in the uk off ebay
[09:58:23] <SolarNRG> that devive has now packed in
[09:58:27] <SolarNRG> device sorry
[09:58:39] <CaptHindsight> I'm Mr Typo today
[09:58:48] <SolarNRG> it had a carbon filter, my pressurecooker+stainless pipe doesn;t
[09:59:50] <SolarNRG> I think I took the fluoride out but there's still volatiles in the condensed water and I need a carbon filter to get them out they make the water tase like weird
[10:00:41] <CaptHindsight> the principal behind the activated carbon filters is setting up a torturous course through the carbon particles that have a very large surface area
[10:01:10] <CaptHindsight> it's finding the right carbon and then getting it to pack densely
[10:01:28] <SolarNRG> I tried using epoxy and charcoal but it took forever and it made the ppm go up, I'm guessing charcoals the "wrong carbon"
[10:01:56] <CaptHindsight> SolarNRG: where are you located?
[10:02:04] <SolarNRG> Earth obviously
[10:02:16] <SolarNRG> It's this blue planet orbiting sol in the milky way galaxy
[10:02:20] <SolarNRG> :)
[10:02:37] <CaptHindsight> some places are more difficult to ship "chemicals" to than others
[10:02:47] <SpeedEvil> SolarNRG: why are you distilling water
[10:03:29] <SolarNRG> Because I believe there's going to be a major drought soon and I want the ability to turn seawater into drinkable water
[10:03:55] <SpeedEvil> lolz
[10:04:20] <SolarNRG> its no laughing matter, imagine the day no water comes thru the tap and everybody's panic buying bottled water, we die if we don't get water
[10:04:26] <CaptHindsight> SolarNRG: http://www.cabotcorp.com/solutions/products-plus/activated-carbon
[10:04:32] <SolarNRG> cheers
[10:05:14] <SolarNRG> there's no shopping cart
[10:06:16] <SolarNRG> what shop would sell this product?
[10:06:45] <CaptHindsight> http://www.amazon.com/Premium-Bulk-Activated-Carbon-Pellet/dp/B00867VNPK several versions here but not many with data
[10:07:05] <CaptHindsight> you really don't know what you're getting
[10:07:30] <SpeedEvil> Distilling in that manner is very, very, very energy inefficient
[10:08:11] <SolarNRG> speedevil Not if ur using SOLAR eNeRGy :)))
[10:08:55] <CaptHindsight> so you're heating the salt water with solar and then just want to pass it through a carbon filter?
[10:09:04] <SolarNRG> Cpthindsight, I see what u mean, a lot of money for dubious quality carbon not adapted into a filter
[10:09:13] <CaptHindsight> yeah
[10:09:17] <SpeedEvil> SolarNRG: where do you live
[10:09:24] <CaptHindsight> so you have to shop around
[10:10:11] <CaptHindsight> http://www.lenntech.com/library/adsorption/adsorption.htm
[10:10:18] <SolarNRG> well I got a big dish covered in mirrors and gears and nemas and geckos and light dependent resistors and I got a pressure cooker and I got some black steel that goes up to like 400 degrees in the sun so I figured i put the pressure cooker on there with the pipe going to the back of the dish and a jug to collect the water hey presto u got clean water
[10:10:41] <SolarNRG> its not quite hot enough to light my cigarette off
[10:10:46] <SolarNRG> but still hot enough to boil water
[10:12:19] <SolarNRG> well according to cabotcorp's website it says it uses basically the same carbon for inkjet print heads so maybe an old printer might work!?
[10:14:41] <Tom_itx> SolarNRG that's why i have a backup well
[10:14:46] <CaptHindsight> SolarNRG: have a link to that?
[10:15:10] <SolarNRG> http://www.cabotcorp.com/solutions/products-plus/inkjet-colorants-and-inks/inkjet-pigment-dispersions
[10:15:18] <SolarNRG> tom_itx u got a well?
[10:15:27] <SolarNRG> like as in jack and jill well?
[10:15:35] <SolarNRG> with the metal bucket and the rope?
[10:15:46] <CaptHindsight> SolarNRG: those are different carbons
[10:16:16] <CaptHindsight> some black inkjet inks use carbon blacks
[10:16:33] <Tom_itx> SolarNRG, no bucket... can be hand pumped
[10:16:55] <SolarNRG> yeah I found that out the hard way with the charcoal, high school science deceived me in thinkin there's only graphite, diamond, graphene, nanotubes and buckyballs. seems I was wrong
[10:17:29] <SolarNRG> I have no idea why one carbon takes pollutants out of water and the other adds pollutants in
[10:17:55] <SolarNRG> I can make carbon easily enough but activated carbon? u lost me
[10:18:16] <SolarNRG> tom_itx u ever tested ur well water with an ec meter
[10:18:17] <Tom_itx> one is older than the other?
[10:18:46] <Tom_itx> at what point does a compost pile become carbon?
[10:19:23] <SpeedEvil> never
[10:20:35] <CaptHindsight> SolarNRG: activated carbon is a form with lots and lots of pores. This gives the particles very high surface area
[10:21:05] <CaptHindsight> the greater the surface area the more they can absorb
[10:22:05] <CaptHindsight> think of a smooth ball vs the same ball with 1,000 holes drilled into it to increase the surface area
[10:22:39] <CaptHindsight> activated carbon is this on the nanoscale
[10:29:04] <SolarNRG> so if I get a block of charcoal and drill lots of 0.1mm holes in it would that work?
[10:29:29] <CaptHindsight> 1 -100nm holes :)
[10:30:18] <SolarNRG> I haven't got a drill bit that small
[10:31:15] <SolarNRG> a carbon filter is obviously beyond my engineering abilities
[10:31:47] <CaptHindsight> you might be able to find filter material that you can stack to make a large filter
[10:31:48] <SolarNRG> I can do the big stuff, I can weld scrap together all day long but stuff that small no idea
[10:32:16] <SolarNRG> what salvagable products have carbon filters in?
[10:32:55] <Tom_itx> go to sams and get a carbon filter
[10:33:01] <Tom_itx> from a RO system
[10:33:07] <SolarNRG> ro system?
[10:33:19] <Tom_itx> reverse osmosis
[10:34:08] <SolarNRG> I spoke to the reverse osmosis dude, he can get the water down to 50ppm but under EU law they must "enrich" the water with something he didn't even know what it was, i.e. the systems he sells MUST add SOMETHING to the water by law
[10:34:29] <Tom_itx> they have several filters on them
[10:34:45] <SolarNRG> u sure I just get the carbon filter it doesn't have the "enrichment" thing already inside?
[10:34:54] <Tom_itx> nope
[10:35:27] <Tom_itx> you can get one and test the water coming out
[10:35:34] <SolarNRG> also his system is designed for no energy, just water pressure makes the ppm go down u sure if I put a piping hot stainless pipe on the end of that I won't kill it?
[10:36:45] <SolarNRG> like RO uses 0watts per day to make 50 gallons of 50ppm water
[10:36:47] <CaptHindsight> http://chemical.eng.usm.my/bassim/user/cimage/clip1.jpg the scale is blurry but those pores are ~.0005" dia
[10:37:10] <Tom_itx> http://science.howstuffworks.com/reverse-osmosis.htm
[10:37:15] <SolarNRG> how the heck do they make that?
[10:37:29] <Tom_itx> RO desalinator
[10:37:52] <SolarNRG> they want like 2k for a RO installation in my house
[10:38:00] <SolarNRG> I bought a pressure cooker for like 55
[10:38:06] <SolarNRG> and a stainless pipe for a tenner
[10:38:17] <Tom_itx> you can get em for under 200
[10:38:26] <Tom_itx> just about anywhere
[10:38:39] <SolarNRG> not here, they are 2k here
[10:38:47] <Tom_itx> move?
[10:38:51] <SolarNRG> to where?
[10:38:59] <Tom_itx> some place cheaper?
[10:39:20] <CaptHindsight> http://www.youtube.com/watch?v=dPabNV7TFFo How to make Activated Charcoal
[10:39:31] <SolarNRG> watching :)
[10:40:03] <CaptHindsight> it's similar to watching paint dry
[10:40:24] <SpeedEvil> Making things that are available in train cars is in general failure.
[10:43:29] <SolarNRG> great I know how to make charcoal that's easy, he goes on and on and on
[10:43:43] <Tom_itx> http://en.wikipedia.org/wiki/Reverse_osmosis
[10:43:57] <Tom_itx> that leads me to believe the carbon filters don't add anything
[10:46:39] <Tom_itx> but go ahead and make your own if you want
[10:48:45] <Tom_itx> http://www.keystonefilter.com/products-solutions/industrial-filter-cartridges-bags?pi_ad_id=16866329838&gclid=CNLGtLqr3MECFQcSMwodoBgA9w

[10:49:51] <Tom_itx> http://www.purewaterproducts.com/cartridges/size1/
[10:51:47] <SolarNRG> out of that list I'd say the Pentek ChlorPlus 10 for 33 bucks isn't bad
[10:52:47] <SolarNRG> uses activated carbon, gets rid of the "chloramines" whatever they are
[10:52:58] <SolarNRG> some chlorine containing molecule I guess
[10:53:21] <CaptHindsight> http://en.wikipedia.org/wiki/Chloramine
[10:53:49] <Tom_itx> if you're worried about steam run it thru a cooler first
[10:55:11] <SolarNRG> well tom after going through a 2m pipe it's already lost a lot of heat from pressurized 100+ it's gone down to like 74 degrees when it gets to the jug
[10:55:35] <SolarNRG> Suppose I could wrap the stainless tube in copper pipe and flow water round it for extra cooling,
[10:56:01] <Tom_itx> just make a whiskey still
[10:56:18] <Tom_itx> dual purpose then
[10:56:46] <roycroft> you have to flow through a carbon filter very slowly to remove chloramine
[10:56:51] <CaptHindsight> can you feed the water into a fermented grain mash and then distill it second time?
[10:57:12] <roycroft> you don't distill a mash, capthindsight
[10:57:17] <CaptHindsight> Tom_itx idea ^^
[10:57:24] <roycroft> you distill the beer the yeast make from the mash
[10:57:57] <CaptHindsight> i was thinking whiskey
[10:58:01] <roycroft> right
[10:58:11] <roycroft> you have to make beer before you can make whiskey
[10:58:32] <roycroft> extract sugar from grain to make mash
[10:58:34] <roycroft> ferment mash to make beer
[10:58:36] <Tom_itx> if the world got to the point there was no fresh water i may be more inclined to want whiskey anyway
[10:58:39] <roycroft> distill beer to make whiskey
[10:59:31] <SolarNRG> ooohh I seee
[10:59:46] <SolarNRG> You mean instead of worrying about water I should be trying to make some spirits with this?
[10:59:47] <roycroft> tom_itx: it's widely held that one of the main reasons beer became popular was because it was a way to consume non-potable water
[11:00:20] * roycroft has been a homebrewer for over 30 years, and is pretty dedicated to brewing
[11:00:23] <SolarNRG> You know I thought about doing something like that with a PID controller, but the key is using the PID to keep the temperature constantly a couple of degrees above the boiling point of ethanol
[11:00:24] <CaptHindsight> are the limits on home brewing different for whiskey vs beer? or is it just based on the amount of ethanol per person?
[11:00:35] <Tom_itx> roycroft yeah i know
[11:00:43] <SolarNRG> reminds me of rum diaries with johnny depp
[11:00:54] <SolarNRG> "there's no such thing as 400% proof", *takes a sip" :o
[11:00:59] <roycroft> new zealand is the only country in the world where it is legal tohome distill
[11:01:50] <roycroft> in the us, federal law allows one to brew up to 100 gallons/year of beer (and the way the law is written, up to 100 gallons of wine as well, but the intent is generally considered to be 100 total)
[11:01:51] <CaptHindsight> so boiling beer is a grey area?
[11:01:56] <roycroft> in a household, up to 200 gallons
[11:02:03] <roycroft> no, it's not a grey area
[11:02:05] <roycroft> it's clearly illegal
[11:02:13] <roycroft> any form of distillation is illegal
[11:02:19] <roycroft> including freeze distillation
[11:02:20] <CaptHindsight> if you condense it
[11:02:37] <SolarNRG> thank fuck I don't live in a dictatorship
[11:02:38] <CaptHindsight> interesting
[11:03:09] <roycroft> only last year did the last of our states legalize homebrewing
[11:03:23] <roycroft> alabama and mississippi were the two last holdouts
[11:03:24] <CaptHindsight> roycroft: how difficult is it to get licensed as a distillery in the US?
[11:03:30] <roycroft> bugt now it is legal in all 50 states
[11:03:44] <roycroft> most state laws have the same limits as the federal law
[11:03:47] <Tom_itx> CaptHindsight they have tons of laws for that
[11:03:53] <roycroft> that depends on the state
[11:04:13] <roycroft> you first of all need an license from atf, which is a lot of paperwork and background check stuff
[11:04:23] <roycroft> and then you need a license from your state liquor control board
[11:04:28] <CaptHindsight> I looked into it ~10 years ago
[11:04:39] <roycroft> for microdistilleries it's becoming increasingly easy at the state level
[11:05:00] <SolarNRG> and those laws were passed by people who claimed to represent you who you voted for and your vote was counted by an insecure electronic system known as GEMS that even a kid armed with MS access could hack
[11:05:14] <CaptHindsight> what defines micro?
[11:05:29] <roycroft> that again depends on the state
[11:05:33] <SolarNRG> I'm sure there is a regulatory body that defines it
[11:05:35] <CaptHindsight> heh,
[11:05:41] <SolarNRG> probably the atf
[11:05:43] <roycroft> and i don't even know the range of production output that the states use
[11:05:54] <Tom_itx> 100k sq ft i doubt is 'micro'
[11:06:07] <roycroft> it's not the size of the distillery
[11:06:11] <roycroft> it's how you use it
[11:06:17] <SolarNRG> right
[11:06:34] <roycroft> although there have been some strange laws that are vessel-related
[11:06:38] <SolarNRG> I'd rather have a a fully automated one that made good quality shite rather than meth that makes u blind
[11:06:45] <roycroft> in belgium the tax on ale used to be based on the capacity of the mash tun
[11:07:26] <roycroft> so the belgian brewers came up with methods to maximize the amount of beer they could make with their mash tun
[11:07:43] <CaptHindsight> are there any regulations on in-belly fermentation?
[11:08:05] <SolarNRG> I don't know, where I live they sell pirate DVDs down the market in broad dayligh
[11:08:20] <CaptHindsight> or is that gut fermentation?
[11:08:45] <SolarNRG> if ur in the US like everything's illegal
[11:08:54] <CaptHindsight> http://en.wikipedia.org/wiki/Auto-brewery_syndrome
[11:09:30] <roycroft> methanol boils at 64.7 degrees, ethanol at 78.37 degrees
[11:09:40] <roycroft> if you're distilling, the methanol will boil off first
[11:09:52] <SolarNRG> woah a few hundred bucks a bogus diagnosis and hey presto that DUI charge is gone
[11:09:53] <roycroft> toss the first bit of distillate and the methanol is gone
[11:10:13] <CaptHindsight> roycroft: what do they call that first bit?
[11:10:24] <roycroft> i don't know
[11:10:36] <roycroft> i'm sure there's a nice colloquial term for it
[11:10:40] <CaptHindsight> there's some distiller term
[11:10:46] <SolarNRG> roycroft, couldn't u rig up a PID to go to 65 with the k type thermocouple in the distillery and run it for an hour or so and throw away the meths then run again setting the PID to 80 and then keep the eths?
[11:10:47] <roycroft> but i'm not a distiller and haven't studied it extensively
[11:11:05] <roycroft> sure, solarnrg
[11:11:48] <roycroft> but i just said there's a reliable low-tech way to avoid methanol contamination
[11:11:57] <SolarNRG> hey that gives me a cheap idea, can I just boil my water loads before distilling it wouldn't that get rid of the volatiles and make purer water?
[11:12:05] <roycroft> asking if a high tech method would also work seems a rather unnecessary question
[11:12:35] <SpeedEvil> SolarNRG: yes
[11:12:56] <roycroft> can you afford to boil your water before mashing?
[11:13:12] <roycroft> heating water is one of the biggest expenses in brewery
[11:13:21] <SolarNRG> Is the pope catholic and does he help pedophiles get away with their crimes? Yes
[11:13:25] <roycroft> which is why the use processes to reclaim that heat
[11:13:29] <CaptHindsight> he has a big solar cooker
[11:13:53] <SolarNRG> its fucking lethal I bet if u stared into the focal point ud be blind in a second
[11:14:26] <CaptHindsight> somebody from Cyprus was working on one similar
[11:14:31] <SolarNRG> I spend 3 weeks painsteakingly silicon pasting 1/2" mirror tiles all over this dish that weighs like 400kg it took 6 of us to lift it in place
[11:14:46] <CaptHindsight> had difficulty sourcing materials and tools
[11:14:47] <SolarNRG> seriously?
[11:15:07] <roycroft> so you have a piece of machinery that has value
[11:15:12] <SolarNRG> My dad's in Cyprus
[11:15:16] <roycroft> it has limited capacity
[11:15:27] <CaptHindsight> yeah, big solar reflector
[11:15:31] <roycroft> when you're using it to boil water unnecessarily you're not able to use it for other things
[11:15:34] <roycroft> so there is a cost to thtat
[11:15:37] <roycroft> that
[11:15:38] <SolarNRG> trouble is though loads of people have done what I've done on kickstarter and they got like no crowd funding
[11:15:59] <roycroft> there is also the labor involved in boiling the water
[11:16:39] <SolarNRG> how long u think u should boil a gallon of water for to get rid of the volatiles?
[11:16:44] <SolarNRG> half an hour?
[11:16:47] <SolarNRG> quarter of an hour?
[11:17:10] <roycroft> i don't know what you mean by "volatiles"
[11:17:23] <roycroft> and i don't know the chemistry of the water you're starting with
[11:17:28] <roycroft> so it's impossible to answer that
[11:17:37] <SolarNRG> oh other random chemicals with boiling points at or below 100 degrees that are making the water unpalettable
[11:17:49] <CaptHindsight> SolarNRG: is your reflector an offset parabolic? http://www.antennamagus.com/images/Newsletter2-3/Offset-parabolic-ray-collimation-newsletter.png
[11:17:56] <SolarNRG> I don't know waht they are, but all I do know is they evaporate with the water leaving something behind
[11:18:07] <SolarNRG> nah its an old sky dish nobody watches sky no more
[11:18:15] <CaptHindsight> I though this was seawater
[11:18:50] <roycroft> most water potability issues are due to microbes in the water, not vocs
[11:18:53] <CaptHindsight> thought/though
[11:19:55] <roycroft> and in a beer/distilled beverage, most of the off flavor compounds you'll be dealing with are inorganic, not organic
[11:21:03] <roycroft> for beer you will be boiling the mash anyway, so there's no reason to pre-boil the water
[11:21:18] <roycroft> i'm not sure if the whiskey distillers boil their mash or not
[11:22:10] <roycroft> i should think they would - it would be more cost effective to boil in a big kettle to concentrate the sugar, making a stronger beer, than to run a weaker beer through the distiller
[11:22:19] <CaptHindsight> hmm lost cost molecular sieve... can't find one
[11:23:59] <SolarNRG> I'm doing tap water for now just to prove I can do it before I start welding stuff together
[11:24:07] <SolarNRG> then I'm going to do tests on seawater
[11:24:48] <SolarNRG> And when I'm satisfied I can turn seawater into drinkable water using the sun on an acceptable scale I'll do it again and again and again until I got an olympic sized swimming pool and have a splash
[11:29:00] <CaptHindsight> http://www.sciencemag.org/content/343/6172/752 Precise and Ultrafast Molecular Sieving Through Graphene Oxide Membranes
[11:29:40] <CaptHindsight> probably already filed for patent so it won't be cost effective for 20+ years
[11:31:22] <CaptHindsight> LOL brought to you by ISIS http://www.i-sis.org.uk/Graphene_Molecular_Sieves_for_Desalination_and_Purifcation.php
[11:31:41] <CaptHindsight> Institute of Science in Society (ISIS)
[11:34:23] <SolarNRG> Funny that, because the MSM ISIS don't call themselves that they call themselves Al Caliphate
[11:34:48] <SolarNRG> So maybe the Institute are the real terrorists, darn scientists!
[11:37:06] <SolarNRG> anyway, thanks for all ur input guys I g2g suppers' served
[11:37:09] <SolarNRG> in a bit

[11:42:01] ChanServ changed topic of #linuxcnc to: LinuxCNC is a linux-based open-source CNC control. | Latest release: 2.6.4 | http://www.linuxcnc.org
[11:57:44] <SpeedEvil> Forward osmosis looks fun
[13:47:42] <os1r1s> Anyone know if a bbb can link up to a 7i77 mesa?
[14:08:22] <Connor> os1r1s: Maybe using a 7I92 Ethernet I/O card
[14:09:27] <zeeshan> are Z axis brakes normally closed
[14:09:35] <Connor> Yes.
[14:09:45] <zeeshan> okay i guess i gotta inject 24V 20W
[14:09:47] <Connor> and energized when the servo is under power.
[14:09:48] <os1r1s> Connor: Thx. I'll take a look
[14:09:49] <zeeshan> through this brake to release it
[14:10:08] <zeeshan> what about for X and Y
[14:10:23] <Connor> os1r1s: I have NO idea if they're drivers for the 7i92 for bbb
[14:10:35] <Connor> Normally not breaks on X and Y
[14:15:14] <zeeshan> i found something interesting today
[14:15:23] <zeeshan> the house builder wired one of my light switches
[14:15:25] <zeeshan> on the neutral line.
[14:15:34] <Connor> Ick.
[14:15:36] * zeeshan thinks this is why you should always check
[14:15:45] <Connor> I hope you didn't find out the HARD way
[14:15:48] <zeeshan> no i didnt
[14:15:54] <zeeshan> i was putting in a dimmer
[14:15:55] <zeeshan> and i realize dit
[14:16:00] <zeeshan> i double checked with a volt meter
[14:16:21] <zeeshan> i checked all the other circuits in the house
[14:16:25] <zeeshan> only one was like this
[14:16:35] <zeeshan> maybe electricians did the work
[14:16:43] <zeeshan> and the people putting up the drywalls disconnected the switch
[14:16:46] <zeeshan> and didn't put it back properly
[14:17:20] <roycroft> i recently found a 110vac recepticle in my house that was wired for 220vac
[14:17:32] <zeeshan> roycroft: nice
[14:17:34] <zeeshan> lucky!
[14:17:39] <roycroft> yes
[14:17:41] <roycroft> free voltage
[14:18:14] <roycroft> i guess it's for european appliances
[14:35:37] <Tom_itx> zeeshan block the spindle up before you release the brake the first time
[14:36:32] <zeeshan> lol
[14:36:36] <zeeshan> i already remvoed it
[14:36:41] <zeeshan> the table flew down :P
[14:37:08] <pcw_home> no estop on gravity
[14:37:40] <Tom_itx> well at least don't stick your head under it to check the spindle taper etc...
[14:37:51] <zeeshan> my spindle head doesnt move
[14:37:56] <zeeshan> well it mvoes, but in Y direction
[14:38:08] <zeeshan> table moves in X and Z
[14:38:35] <Tom_itx> horizontal?
[14:40:06] <zeeshan> http://www.youtube.com/watch?v=Hs5lYs71O-A
[14:42:53] <skunkworks_> that is different...
[15:25:54] <Tom_itx> eerie... was scheduled to do some work for one of those in the plane crash this week
[16:17:07] <Deejay> gn8
[17:19:53] <cpresser> has anybody tried to build a handwheel-encoder DIY-Style? I just found this schematic: http://www.b-pahl.de/bastel/portalfraese/handrad/inkrementalgeber.GIF
[17:21:04] <Tom_L> i like the feel of the commercial ones
[17:21:27] <Tom_L> all you need is a 100 count quad encoder
[17:24:20] <PetefromTn_> I just buy them but I do have an article in Digital machinist somewhere that shows using some of the heavier rubber magnet material sheets to fabricate one. It looked pretty neat actually.
[17:39:46] <yeahiiii> hey, does anyone know if this http://www.amazon.com/ASRock-Motherboard-Mini-DDR3-Q1900B-ITX/dp/B00J2CCCJE/ref=sr_1_3?ie=UTF8&qid=1414970384&sr=8-3&keywords=Q1900M is a suitable board for linuxcnc?
[17:43:18] <pcw_home> it is and it isnt...
[17:43:20] <pcw_home> its fast, low power, and has decent latency but the current RTAI kernel doesnt support the USB on the J1800,J1900,J2950s etc
[17:43:21] <pcw_home> This shoudl be fixed soon (working kernels are available but are not part of the ISO image corrently)
[17:50:13] <yeahiiii> do you have some real milling experience with it? I actually don’t really care about usb on my machine
[17:52:06] <pcw_home> I dont have any experienece other than long term latency testing/ testing with our Ethernet I/O catds
[17:53:35] <pcw_home> if you are planning on doin software step motor control out the parallel port you will need the RTAI kernel so having no USB may be a nuisance (at least temporarily)
[17:54:56] <pcw_home> for example you could n ot boot from a usb stick to do the linuxcnc installation and you woudl need a PS2 KB and mouse
[17:56:36] <pcw_home> I do expect the RTAI kernel issue to be fixed shortly
[17:59:32] <yeahiiii> indeed thats not really convinient, but I should be able to get around this issue. Its just too hard to find one of the old atom boards for a reasonable price. Maybe I should just try again to use my quite new i3 haswell.
[18:00:57] <Computer_Barf1> I need a jumper to enable the servo pins on my ramps.. Is there any jumpers on ramps that are on the board by default but are unused?
[18:01:03] <yeahiiii> Any idea what might be wrong if jitter jumps to 50000 right after staring glxgears? Already limited the system to 1 core, turned off hyperthreading, added idle=poll and turned of all power management settings i could find -.-
[18:01:21] <pcw_home> the (very chesp) G3220/G3258 seem very good (tested with a Gigabyte H81 motherboard) so higher end Haswells should be good
[18:01:30] <pcw_home> cheap
[18:01:58] <pcw_home> what CPU?
[18:02:04] <Computer_Barf1> woops sorry guys wrong chat room
[18:04:29] <yeahiiii> this cpu http://www.newegg.com/Product/Product.aspx?Item=N82E16819116946&cm_re=Intel%u00ae_Core%u2122_i3-4130-_-19-116-946-_-Product on this board http://www.newegg.com/Product/Product.aspx?Item=N82E16813131994&cm_re=Asus_H87M-PRO_H87-_-13-131-994-_-Product
[18:05:10] <yeahiiii> (tested with the 2.6 wheezy hybrid image)
[18:06:22] <yeahiiii> oh and you were right http://psha.org.ru/irc/%23emc-devel/2014-10-24.html
[18:06:33] <yeahiiii> seems like usb is already working on the j1900 boards
[18:06:41] <pcw_home> are all power management systems turned off in the BIOS?
[18:07:04] <pcw_home> some have non-obvious names (EIS?)
[18:09:09] <yeahiiii> I currently don’t have this machine close to me, I turned off all the obvious ones first, got bad results, checked again and found some more. Although I am not 100% sure that I found all of them, I am pretty sure.
[18:09:55] <yeahiiii> It’s a bit weird. I can run 5-10 windows of youtube videos and stay below 20k-25k. glxgears lets it jump to 50k instantly
[18:10:02] <pcw_home> At least on preemt-rt it much better to run all CPUs
[18:11:07] <pcw_home> and isolcpus seem to make things worse
[18:11:43] <yeahiiii> hm haven’t checked any other kernels than the rtai this wheezy image ships with
[18:12:00] <yeahiiii> probably should do this and double check on the bios options
[18:12:38] <pcw_home> unless you know isolcpus helps I would not use it
[18:13:20] <yeahiiii> running the machine withouth isolcpus didn’t help either =/
[18:13:59] <pcw_home> well if it makes no latency difference, its better to not use it
[18:14:20] <pcw_home> you might try the preemt-rt kernel
[18:17:02] <pcw_home> sudo apt-get install linux-image-3.2.0-4-rt-686-pae
[18:17:48] <yeahiiii> yepp, will try that tomorrow (1 am here)! thanks for your hints!
[20:00:37] <zeeshan> scoree
[20:02:49] <zeeshan> http://i.imgur.com/X63Oy9D.jpg
[20:03:01] <zeeshan> picked up all that for $30
[20:03:18] <zeeshan> i'm not sure what that blue thing is on the corner
[20:03:24] <zeeshan> looks like something for a height gauge
[20:08:17] <ssi> nice
[20:12:26] <zeeshan> finally have jack screws
[20:12:26] <zeeshan> lol
[20:12:31] <zeeshan> what are you utpo
[20:12:57] <XXCoder> ew TMI zeeshan
[20:14:51] <LeelooMinai> zeeshan: I bought 4 from KBC once - they have those super cheap (Machinist Jacks): http://kbctools.com/usa/Navigation/NavPDF.cfm?PDFPage=778
[20:15:35] <zeeshan> well two of them are starrett
[20:15:38] <zeeshan> and i really wanted starrets!
[20:15:59] <zeeshan> the other two are fowler :/
[20:16:12] <LeelooMinai> E, is this some kind of machinist world Fluke and Appple equivalent? :)
[20:16:33] <LeelooMinai> Where you pay for the name mostly?
[20:16:37] <zeeshan> nah
[20:16:49] <zeeshan> starrett, mitutoyo make higher quality stuff
[20:17:01] <zeeshan> in comparison to chinese stuff
[20:17:08] <zeeshan> taiwanese stuff for some things comes close
[20:17:10] <LeelooMinai> Yes, but 2x better and 5x more expensive:)
[20:17:22] <zeeshan> well thats unfair to say
[20:17:29] <zeeshan> if you compare chinese collets vs say..
[20:17:33] <zeeshan> glacern collets
[20:17:43] <zeeshan> its 0.0008-0.0006 vs 0.0001
[20:17:46] <zeeshan> runout
[20:17:58] <zeeshan> so in that case ic an say they're 6 to 8x better :P
[20:18:18] <LeelooMinai> Yes, I guess sometimes it's worth the price, but not always
[20:18:18] <zeeshan> i try to buy name brands because they also have a better resale value
[20:18:26] <zeeshan> to give you an example
[20:18:43] <zeeshan> i'd never run a cheapo dial indicator (ahem made in china special) indicator
[20:18:57] <zeeshan> they have huge errors over their travel
[20:19:16] <zeeshan> even the insize dial indicator made in taiwan has about 2 thou over 1"
[20:19:40] <zeeshan> and last reason is i'd liek to support our economy
[20:20:48] <LeelooMinai> Right, well, I don't have moreals like that I'm afraid - I just buy from whomever can offer best value.
[20:21:03] <LeelooMinai> Maybe I will go to hell for this - not sure:)
[20:21:07] <zeeshan> p.s. fluke multimeters make chinese ones look like crap
[20:21:18] <zeeshan> im sure you've seen eev's channel
[20:21:21] <zeeshan> on comparing em
[20:21:29] <jdh> I have fluke, and I have 10 chinese ones
[20:21:42] <LeelooMinai> They made model for CHina too (FLuke).
[20:21:45] <zeeshan> jdh whats your opinion
[20:21:52] <jdh> 99% of the time, the chinese ones are fine for what I need
[20:22:01] <LeelooMinai> I would not buy Fluke multimeter though - they are ok, but far overpriced.
[20:22:07] <jdh> and they are free
[20:22:10] <zeeshan> haha
[20:22:37] <zeeshan> when it comes down to things i care about
[20:22:44] <zeeshan> i liek to buy the good stuff
[20:22:54] <jdh> there are two within reach of me here (and 2 chinese digital calipers)
[20:22:55] <zeeshan> i was rebuilding my trnamission
[20:23:01] <zeeshan> and usually for that stuff the chinese indicators work okay
[20:23:02] <macpod> Hi all, I'm running 2.6.4 currently and found a axis bug. In the opengl display one of the views improperly shows the positions of the spindle. I've taken screenshots but wondered if there is a good ways to do a "dump" of this
[20:23:08] <zeeshan> but man that pos wasn't reading right
[20:23:21] <zeeshan> chinese digital calipers are great!
[20:23:26] <zeeshan> i did a test on them a while back
[20:23:31] <zeeshan> they're just as accurate as a mitutoyo
[20:24:15] <LeelooMinai> I like mine - they only drawback is that after while it requires more zeroings, but it was worth the price ($15 or so:)
[20:24:23] <jdh> $9.99
[20:24:33] <jdh> almost as good as free chinese voltmeters
[20:24:37] <zeeshan> mine were $10 from canadian tire
[20:24:38] <zeeshan> on sale
[20:24:38] <zeeshan> haha
[20:24:52] <jdh> I have seen flakey flukes
[20:24:57] <zeeshan> that being said, i use the mitutoyo only for inspection
[20:25:20] <jdh> spent hours of frustration until I finally tried another meter.
[20:29:24] <ssi> ooh thanks for reminding me
[20:29:32] <ssi> I need to put my fluke 179 on the inventory list
[20:30:11] <ssi> 189 excuse me
[20:37:46] <jdh> we had to finally turn the heat on last night :(
[20:37:56] <ssi> yeah it was damn cold this wkd
[20:38:00] <ssi> supposed to warm up next couple days
[20:41:42] <zeeshan> NEED WINTER TIRES :[
[20:41:49] <ssi> sucks for you
[20:41:52] <ssi> I just need tires :(
[20:41:58] <jdh> no kidding
[20:41:59] <ssi> my left rear has a slow leak
[20:42:17] <ssi> I think from running over something nasty in the driveway of the disaster area I used to call a house
[20:42:19] <jdh> what do you do with your non-winter tires in teh winter?
[20:42:32] <zeeshan> store em in the basement
[20:42:45] <jdh> what's a basement
[20:43:01] <zeeshan> google
[20:43:02] <zeeshan> :-)
[20:49:40] <XXCoder> make non-winter tires fort
[20:51:20] <zeeshan> man im so glad i ditched diptrace for making schematics
[20:51:27] <zeeshan> autocad electrical is so much better
[20:54:43] <jdh> one is $75, one is $4400
[20:54:57] <zeeshan> meh
[20:54:59] <zeeshan> student version
[20:55:00] <zeeshan> free
[20:55:17] <jdh> thats supporting the economy
[20:55:34] <zeeshan> ??
[20:55:51] <zeeshan> if i was a business i'd buy autocad , solidworks blah blah in a heartbeat
[20:56:01] <zeeshan> i will one day when i have my own consulting firm
[20:56:04] <zeeshan> :-)
[20:58:20] <LeelooMinai> zeeshan: I used to use DipTrace for making PCBs - imho it is pretty good for the price.
[21:02:55] <XXCoder> $75?
[21:03:09] <ssi> I got a full eagle license recently :D
[21:04:18] <LeelooMinai> ssi: On #electronics I always recommend DipTrace over Eagle. Most people agree that it has much better usability - it's easier to create footprints, symbols, maintain libraries, etc.
[21:04:38] <jdh> is there a free version?
[21:05:08] <LeelooMinai> Yes, 300 pin max 2 layer is free, or they can increase it to 500 pin max if you request hobby licence.
[21:05:41] <LeelooMinai> If you start with electronics 500 pins is a lot unless you are doing some crazy fpga project.
[21:05:45] <ssi> since I know how to use eagle, I'm not much concerned about that
[21:06:21] <LeelooMinai> I see people always complaining about Eagle there:)
[21:10:52] <skunkworks_> I found eagle very powerful and hard to learn.. :)
[21:12:07] <ssi> I've produced dozens of four layer boards with it
[21:12:24] <ssi> once you learn it, it's pretty good. Has its foibles, but you have to spend a lot more to do better
[21:13:00] <LeelooMinai> I would rate EDAs as KiCAD -> Eagle -> DipTrace -> big gap -> Altium
[21:13:54] <LeelooMinai> Altium has crazy price, so hobbyist would have to pirate it, though they are having some beta program now and plan to have some kind of free "cloud" version.
[21:17:57] <MrHindsight> -> Altium -> Allegro :)
[21:18:10] <LeelooMinai> I doubt it
[21:18:24] <MrHindsight> what is the going price for Altium?
[21:18:24] <LeelooMinai> Altium is pretty much at the top there
[21:18:32] <LeelooMinai> $5000 or more?
[21:18:47] <MrHindsight> Allegro full suite is >$40k
[21:18:55] <MrHindsight> just wondering
[21:19:32] <MrHindsight> what became of PADS?
[21:19:40] <LeelooMinai> Because they bought all sorts of software and kind of glued it together. Altium is for schematics/pcbs with some SI, but it's very well designed and integrated.
[21:20:40] <MrHindsight> yeah, they tried to do everything including FPGA design
[21:21:07] <MrHindsight> I used Altium a few times to get the hang of it
[21:22:04] <LeelooMinai> Ok, apparently Altium is $7k or so - kind of too much for average hobbyist:)
[21:22:24] <MrHindsight> deep pocketed DIYers
[21:22:55] <LeelooMinai> imho for hobbyists DipTrace is the best option - it's pretty decent.
[21:23:34] <MrHindsight> does it handle auto trace length matching and controlled impedance?
[21:23:46] <MrHindsight> is it even gridless?
[21:24:11] <LeelooMinai> Last time I used it was 2 years ago (later I used pirated Altium.)
[21:24:39] <LeelooMinai> Not sure what they added since then. Also, depends what you mean by "gridless".
[21:25:17] <MrHindsight> just wondering, I had not even heard of it until now
[21:29:04] <skunkworks_> MrHindsight: did you see? http://electronicsam.com/images/KandT/testing/Screenshot%20from%202014-11-01%2021:59:04.png
[21:29:29] <skunkworks_> Working on it about 10 min a day.. (makes for slow going)
[21:29:46] <Tom_itx> ever run into a pulley grub screw backed up by another one?
[21:29:58] <Tom_itx> i guess to keep it from backing out?
[21:30:01] <skunkworks_> yes
[21:30:12] <Tom_itx> i didn't bother looking for two :)
[21:30:15] <skunkworks_> heh
[21:30:19] <skunkworks_> been there
[21:30:43] <MrHindsight> skunkworks_: nice
[21:30:44] <Tom_itx> i had to make a puller for it... it worked wonderfully but left a gulley in the motor flat
[21:30:59] <Tom_itx> i managed to file it out ok though
[21:31:17] <Tom_itx> i probably wouldn't have needed the puller at all...
[21:32:19] <Tom_itx> anyway, i got some timing pulleys ordered for my spindle / motor
[21:32:21] <MrHindsight> skunkworks_: you have it measuring the diameter and XY position?
[21:34:59] <skunkworks_> in the image - yes
[21:37:14] <LeelooMinai> Any reccomendations for what should I look for/buy for a spindle on small CNC of mine (for milling aluminum mostly)? Something that will not be crazy expensive - max $300 probably or so.
[21:37:35] <jdh> chinese 1.2kw water cooled
[21:37:59] <LeelooMinai> I, I saw those - but they require VFD, right?
[21:38:16] <jdh> they usually come as a set
[21:38:29] <jdh> 800w if you want to stay cheaper
[21:38:42] <LeelooMinai> I must be able to plug the thing into normal mains outlet (110V that is)
[21:38:47] <jdh> yeah
[21:39:08] <LeelooMinai> I saw some VFDs that were only for 3 -phase I think
[21:39:25] <LeelooMinai> I cannot really have this in my bedroom:)
[21:40:01] <jdh> http://www.ebay.com/itm/171066636783
[21:41:09] <skunkworks_> they say they stock 110v versions..
[21:41:33] <LeelooMinai> I wonder if I could control it easily with 7i76 I have
[21:41:50] <LeelooMinai> It has some spindle control outputs
[21:41:52] <jdh> yes, or via modbus most likely
[21:43:34] <LeelooMinai> Will look on aliexpress too - a set with mathching bracket would be nice so I can easily attach it to the z-axis
[21:44:13] <LeelooMinai> they have also a lot of air-cooled ones I see - water cooled are better?
[21:44:41] <jdh> never used an air cooled one. my water cooled one is amazingly quiet
[21:45:08] <LeelooMinai> Probably good bearings etc.
[21:46:00] <os1r1s> Anyone use a fog buster (diy or otherwise)?
[21:46:00] <LeelooMinai> I have proxxon rotary tool - when I first turned it on, I thought there was something wrong with it, because I was used to Dremer-like cheap tools.
[21:46:15] <LeelooMinai> Dremel*
[22:30:30] <Connor> LeelooMinai: Why did you thing something was wrong with it?
[22:30:45] <LeelooMinai> Quiet
[22:31:05] <LeelooMinai> At least compared to "normal" Dremel-like tools I had
[22:34:46] <Connor> Ahh.. okay
[23:39:50] <zeeshan> http://i.imgur.com/7W5fsGn.png
[23:39:53] <zeeshan> slowly coming together
[23:41:41] <zeeshan> i didn't see a timer in the lubricator
[23:41:53] <zeeshan> so i think i'm going to have to use a relay and linuxcnc as a timer
