[03:13:37] <_DJ_> moin
[07:46:58] <jthornton> 100% rain today... my candy will melt
[07:48:46] <PetefromTn> Damn that sux.....
[07:58:30] <jthornton> wow I just created my first android app
[07:59:06] <jdh> cool, what does it do?
[08:07:14] <PetefromTn> Yeah what does it do?
[08:09:12] <jdh> http://tinyurl.com/mnhf8b4
[08:09:22] <jdh> that's my one and only Android app.
[08:09:59] <Jymmm> cause you have an iphone? lol
[08:10:01] <jdh> displays/graphs values from a oxygen cell checker I built (via bluetooth)
[08:11:19] <Jymmm> oh, missed the 'created' part =)
[08:11:33] <Jymmm> jthornton: That sucks =(
[08:11:51] <Jymmm> jdh: was it a pita to write?
[08:12:21] <jdh> not really. I stole some code to start with.
[08:12:39] <Jymmm> ah
[08:12:41] <jdh> never done any java before that though.
[08:13:07] <Jymmm> and the UI dev?
[08:13:20] <Jymmm> err GUI part?
[08:15:06] <jdh> pretty normal for that.
[08:16:27] <Jymmm> jdh: I honestly dont know what that means.
[08:19:20] <jdh> heh... it's just a GUI. Pretty much like working with any other UI framework.
[08:19:58] <Jymmm> fucked?
[08:20:15] <jdh> no more so than any other.
[08:20:34] <Jymmm> Ah, fucked.
[08:20:51] <jdh> I've been writing code for 30+ years. I no longer have favorites or really care what platform/etc.
[08:21:15] <Jymmm> gotcha. I've never written a GUI app
[08:22:01] <jdh> UI is my least favorite part. Not due to framework/etc, just that you have to interact with people and they always do the wrong thing.
[08:22:46] <Jymmm> ctually, I have no issues with the UI part, it's the GUI dev part I find to be a pita
[08:23:01] <archivist_herron> even when people is you
[08:23:25] <jdh> yep.
[08:23:26] <Jymmm> Yeah, I've been studying UI for many years.
[08:24:13] <jdh> I, unfortunately, do a lot of operator interface stuff for work.
[08:24:53] <Jymmm> It's like having a dev write the manual, you dont, becasue they suck at it.
[08:26:30] <PetefromTn> anyone got time for an off topic android stupid question?
[08:27:35] <Jymmm> PetefromTn: Dont ask to ask, just ask. If it's stupid enough, we'll laugh at you.
[08:27:48] <PetefromTn> Okay then..
[08:28:48] <JT_Shop> PetefromTn, it converts from mile to km and back... just following a tutorial
[08:30:12] <PetefromTn> Last night I ripped a CD to my wifes laptop she wanted, worked great. I also uploaded it to my android cell phone last night after I did this. This morning before she went to work she grabbed my charging chord which is also the data cable I use to upload stuff to my android phone. Well I noticed one of the songs did not make it onto my phone so I was wondering if there was an easy way to do it wirelessly. I tried emailing
[08:30:13] <PetefromTn> the file to myself and then downloading it on the phone but it only allow me to play it not insert it into the proper album file..
[08:30:48] <jdh> android?
[08:30:54] <PetefromTn> she took the chord to work with her accidentally...
[08:30:58] <PetefromTn> Yup Android..
[08:31:16] <Jymmm> PetefromTn: https://play.google.com/store/apps/details?id=com.sand.airdroid
[08:31:33] <jdh> get a file explorer app, find the file in teh downloads, copy it to your music dir
[08:31:33] <PetefromTn> Was really wanting to listen to this whole album in the shop using my android phone on the stereo.
[08:32:30] <PetefromTn> Ooh interesting.... Was not aware of such a thing... have you used that one in particular?
[08:32:46] <Jymmm> All the time
[08:33:05] <Jymmm> You can even stream music from your device via a browser on your computer.
[08:33:53] <PetefromTn> awesome... Amazing this stuff nowadays huh. I freakin' love my android phone I think it is physically attached to my hand now LOL
[08:35:08] <PetefromTn> just downloaded it to my phone..
[08:35:41] <jdh> ES File Explorer
[08:35:42] <Jymmm> If you want your music everywhere https://play.google.com/store/apps/details?id=com.google.android.music
[08:36:14] <Jymmm> jdh: Yeah, I have that too. love that it connects to my NAS box =)
[08:36:48] <PetefromTn> I have TONS of music on my phone now.... It is unbelievable to have that much capacity of digital skip free music anywhere. Beats the crap out of boxes and boxes of CD's in your car...
[08:36:59] <PetefromTn> whazza Nas box?
[08:37:37] <Jymmm> NAS = Network Attached Storage... 8TB of RAID5 goodness
[08:37:41] <PetefromTn> do you guys register with the software or just skip?
[08:38:09] <PetefromTn> 8TB!!! HOLY SMOKES!! What in gods name could you possibly do with that much storage?
[08:38:30] <jdh> extensive pr0n collection.
[08:38:36] <PetefromTn> LOL..
[08:38:38] <jdh> we don't judge.
[08:38:44] <PetefromTn> thats a lotta whackin'
[08:39:10] <Jymmm> Nah, porn is only 3GB
[08:39:23] <skunkworks> here at work we have a total of about 35tb of storage plus another 10 or more offsite
[08:39:24] <PetefromTn> did you guys register with the air setup?
[08:39:36] <Jymmm> PetefromTn: Entire media collection... music, movies, etc
[08:39:38] <Jymmm> PetefromTn: no
[08:40:11] <Jymmm> PetefromTn: Unless you want remote access away from your LAN
[08:40:18] <skunkworks> (which isn't much now day)
[08:40:22] <Jymmm> and I personally question that
[08:40:26] <PetefromTn> so you dont have to register your email
[08:40:38] <Jymmm> PetefromTn: No, and it says you dont too
[08:41:58] <PetefromTn> Okay thanks so much fellas gonna play with this app and see how it works now.. Be back in a bit.
[08:51:35] <Loetmichel> PetefromTn: thx for the comment...
[08:51:52] <PetefromTn> what I don't get is where to go to on the laptop to interact with the phone here...
[08:52:02] <PetefromTn> Loetmichel: ;)
[08:52:03] <Loetmichel> PetefromTn: 8tb is nothing... had just sold a few NAS with 5 times 4gb disks in it
[08:52:52] <Loetmichel> = 16gb useable raid5
[08:54:21] <Loetmichel> and that were really small boxes
[08:54:34] <Jymmm> Big difference between sold and owned.
[08:54:41] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14184
[08:55:20] <PetefromTn> Okay I got the file into the libraby but I cannot seem to get it loaded into the right album folder. There is two albums by the same artist and it is in the wrong one..
[08:55:33] <Loetmichel> i OWN a fileserver with a 1tb disk in... if i find time the 2 4tb disks i bought for it will go in, so it will have 9tb...
[08:55:47] <Loetmichel> @ Jymmm
[08:57:10] <Jymmm> Loetmichel: The next NAS I build will be 5x 4TB raw
[08:57:58] <Jymmm> as this is starting to fill up. Err 4x4TB ,ore than likely
[08:59:07] <Jymmm> I want to build two of them, one being offsite. But I'm still working on the secure syncing/storage on the remote box.
[08:59:35] <Loetmichel> Jymmm: i know the problem... since the fileserver is also the provider for the networkdrive of the Sat reciver my wife uses not tooo seldom to record TV ;-)
[09:00:34] <Jymmm> Heh, TV shows suck up the most room of all.
[09:02:25] <Loetmichel> but as my wife had rented a sky premium account and the reciver/2tb disk combo (encrypted:-( i expect the fileserver to be MUCH less filled now ;-)
[09:05:21] <PetefromTn> Man it is so much easier to be able to access the phones internals like a web browser or file browser with this app...
[09:05:40] <Valen> small favour to ask, one of the ops in a channel I frequent has said they will do a hamsterdance and post it on youtube if they get 100 people in the #, its currently at 88 through natural means, so if anybody would mind joining #hackvana for a few minutes I'll be sure and relay the hamster dance video later for your amusement
[09:06:26] <PetefromTn> Whazza Hamsterdance?
[09:07:04] <Valen> presumably dancing like a hamster
[09:07:49] <Valen> probably with this music as the background
[09:07:55] <Valen> http://www.youtube.com/watch?v=p3G5IXn0K7A
[09:09:35] <PetefromTn> aah....spellbinding.
[09:09:49] <Valen> rather
[09:18:41] <PetefromTn> Damn music files are NOT cooperating LOL
[09:36:37] * JT_Shop wonders why anyone would assume that more machinists know C over G code
[09:37:12] <JT_Shop> seems silly, if you want to make a G code generator make it conversational
[09:38:47] <archivist> some people just like fixing the wrong problem (not that the current syntax is acceptable)
[09:41:30] <archivist> I must admit I stopped reading that thread at about 7-10 emails
[09:43:30] <Jymmm> Were trying to get someone to post a hamsterdance video if the channel gets to 100 ppl, it's about hobby PCB's /join #hackvana
[09:43:44] <Jymmm> only 9 more ppl needed.
[09:44:32] <PetefromTn> That Airdroid app is sweet when I finally got it online with my computer. Nice to be able to access ANYTHING in my phone at any time..
[09:46:32] <Jymmm> Just a few more need to /join #hackvana - http://dangerousprototypes.com/2012/12/06/workshop-video-interview-with-mitch-from-hackvana/
[09:46:51] <PetefromTn> It was interetsting to link the phone to the laptop using the camera to photograph a wierd barcode thing...
[10:08:20] <JT_Shop> logger[mah]_, log
[10:08:20] <logger[mah]_> JT_Shop: Log stored at http://linuxcnc.mah.priv.at/irc/%23linuxcnc/2013-10-31.html
[10:10:13] <JT_Shop> yea, conversational seems to me to be a more intuitive way to describe your G code than C
[10:10:23] <JT_Shop> dang rain keeps knocking me off line
[10:12:19] <archivist> conversational also seems a bit wrong to me :)
[10:13:25] <archivist> usually because the "conversational" questions miss some thing an odd job needs
[10:15:22] <archivist> like miss out the taper lead in/out from screw cutting
[10:16:43] <JT_Shop> that is part of the threading cycle right?
[10:18:39] <JT_Shop> I'm thinking about the newnotknowanything guy being able to type in rapid X1.3 Y-0.25 type of inputs
[10:19:02] <JT_Shop> spindle speed 1500
[10:19:05] <JT_Shop> spindle on
[10:19:13] <JT_Shop> feed rate 5
[10:19:22] <JT_Shop> feed z-.375
[10:19:26] <JT_Shop> etc
[10:19:35] <archivist> may as well use a manual lathe :)
[10:19:43] <JT_Shop> lol
[10:20:04] <JT_Shop> yea quicker to use QCad CAM I guess
[10:20:31] <archivist> I dont use any artificial cam at the moment
[10:21:09] <archivist> I do use mdi a bit
[10:23:05] <JT_Shop> I guess it depends on what your doing and your level of expertise
[10:24:57] <archivist> I am wondering if one spoon feeds a noob with easy buttons if he can progress from there easily
[10:25:34] <archivist> I realise many want that though
[10:27:50] <JT_Shop> yea, the mack crowd wants the big easy button
[10:59:40] <PetefromTn> Just realized that this onen song I am having trouble with is on the same album but when you open the album in file browser that particular song shows it is from another album. Just wanted them all to be under the same album is that possible to change?
[10:59:48] <PetefromTn> one
[11:01:27] <PetefromTn> Oops I think I just figured it out... Right click/properties/adjust
[11:17:34] <skunkworks> pcw_home, is there something I could test with the Dpll and the 7i80?
[11:31:35] <pcw_home> I think the DPLL is only used with the absolute encoders at the moment
[11:31:37] <pcw_home> (though it will be used with sserial,SPI quadrature encoders and stepgen eventually)
[11:38:15] <pcw_home> It may be that the DPLL will be there and be functional
[11:38:17] <pcw_home> (so the jitter seen by the 7I80 can be measured) even without
[11:38:18] <pcw_home> any dependent modules like absolute encoders installed
[11:38:20] <pcw_home> but I dont think hm2_ether is merged with master so I
[11:38:22] <pcw_home> dont see a way to test it ATM
[11:46:45] <skunkworks> probably not - I was using the unified build to test the 7i80
[11:46:59] <skunkworks> Iwith it only working on xenomai - it is really the only route
[12:36:15] <Tom_itx> Jymmm, what do i get if i join? Mitch has been trying to get me to join since he started that venture
[13:21:55] <Jymmm> Tom_itx: hamsterdance video
[14:33:44] <JT_Shop> Dang G43 H2 a couple of lines past T1 M6 broke my bit
[14:48:49] <WalterN> heh
[14:49:21] <WalterN> time to see about emergency collets for a royal chuck
[14:49:36] <andypugh> JT_Shop: Simplest not to use H.
[14:50:29] <WalterN> hmm
[14:50:37] <WalterN> is S-30 the collet type or A2-8?
[14:52:57] <WalterN> S-30 is the chuck part I think, and A2-8 is the way the chuck mounts to the machine?
[14:53:32] <WalterN> seems to
[14:53:34] <WalterN> *so
[14:54:31] <WalterN> no, S-30 is the collet type
[14:55:46] <Lathe_newbie> does anyone know, how to build a 100V/10A H bridge with current limitter?
[14:58:17] <jdh> use very thin wire.
[14:59:38] <Lathe_newbie> how to build the bridge i know
[14:59:50] <Lathe_newbie> but how to do the current limiter?
[15:00:14] <jdh> big resistor?
[15:02:46] <WalterN> herm
[15:03:04] <WalterN> not seeing any 4" S-30 style emergency collet things
[15:05:36] <WalterN> if I had a big lathe I suppose I could make one
[15:08:03] <JT_Shop> andypugh, yea I just removed it from the post processor so it can't catch me again
[15:09:04] <andypugh> PCW knows, I feel sure.
[15:09:20] <andypugh> You normally see a track running under a hall chip
[15:10:02] <andypugh> Then I guess some sort of electronical magic to link that to the PWM duty cycle.
[15:11:59] <skunkworks> andypugh, http://bbs.homeshopmachinist.net/threads/61220-Wohlhaupter-Gloat
[15:12:54] <skunkworks> Lathe_newbie, it is complicated...
[15:13:11] <PCW> current sense is normally done either with low value resistors in the bottom side of the Hbridge
[15:13:13] <PCW> or perhaps hall sensors in 2 of the motor leads (for AC)
[15:14:16] <Lathe_newbie> pcw the current detection i know
[15:14:27] <Lathe_newbie> but then i add a low pass filter
[15:14:34] <PCW> for AC servos using Halls is easier
[15:14:34] <skunkworks> http://electronicsam.com/images/KandT/servostart/schem/latestcurrentlimit/latestschem.png
[15:14:41] <Lathe_newbie> and a chopper?
[15:26:30] <Jymmm> jdh: Btw, is your app for scuba tanks?
[15:30:19] <jdh> not directly. It is to check oxygen sensors. They put out a voltage base on partial pressure of oxygen
[15:30:57] <Jymmm> jdh: sensors in what?
[15:31:23] <Jymmm> jdh: diving gear?
[15:31:27] <jdh> they go in my rebreather
[15:31:32] <Jymmm> ah, ok
[15:32:13] <jdh> as they age, they become current limited. You can only really check them in 100% oxygen at 2+ ATA
[15:32:21] <Jymmm> jdh: and how would you "normally" check tham?
[15:32:33] <Jymmm> voltmeter?
[15:32:51] <jdh> they put out ~10mV in air at the surface
[15:33:32] <Jymmm> Ok, time to hang the black lights
[15:33:42] <jdh> but, you need to know that they can accurately measure O2 up to 2ish ATA
[15:45:27] <WalterN> is there a better idea for holding a 4" piece of material in an S-30 chuck?
[15:45:38] <WalterN> chuck/collet
[15:50:42] <WalterN> same issue as this guy http://www.practicalmachinist.com/vb/general/holding-3-jaw-chuck-collet-chuck-238934/
[15:51:16] <WalterN> need to turn 55 pieces of 4" aluminum.. heh
[15:52:17] <WalterN> not sure if I have access to make my own emergency collet
[15:52:23] <WalterN> erm
[15:52:29] <WalterN> access to a lathe big enough
[15:54:58] <JT_Shop> what is a S-30 chuck?
[16:05:14] <Jymmm> jdh: I understand, just wasn't sure how the measurements were taken before your new toy.
[16:05:46] <Jymmm> Ok, blacklights up. Need to do the rest of the cabling
[16:25:38] <WalterN> JT_Shop: one of these... http://www.shophardinge.com/assets/images/ProductShots/ConeS30_400.gif that fits inside one of these... http://cdn.mscdirect.com/global/images/ProductImages/0007532-11.jpg
[16:42:57] <JT_Shop> but your material is bigger than the biggest collet?
[16:43:15] <WalterN> JT_Shop: yeah, by a fair bit
[16:43:45] <WalterN> I think the largest is about 3", maybe slightly smaller... I need to grab on to 4" diameter material
[16:47:20] <JT_Shop> do they have large diameter collets like this http://www.mcmaster.com/#lathe-collets/=p5gvmq
[16:47:51] <JT_Shop> http://www.mcmaster.com/#3208a35/=p5gvyr
[16:49:59] <WalterN> JT_Shop: I havent seen any
[16:50:38] <WalterN> http://www.royalprod.com/content/files/royal_catalog.pdf is their catalog
[16:50:59] <WalterN> they say on there that they make custom sizes, but that would be bloody expensive
[16:52:22] <JT_Shop> can you make something like the link I showed that fits inside your largest collet?
[16:52:36] <WalterN> well
[16:52:41] <WalterN> thats what I was thinking about doing
[16:53:04] <WalterN> not sure if I have access to a manual lathe to do that though
[16:53:36] <WalterN> would need a chunk of 5" steel of some sort
[16:54:24] <JT_Shop> do you have a mill?
[16:54:48] <WalterN> we have a Haas VF1
[16:55:22] <JT_Shop> mill the small end then put it in the lathe to turn the large part
[16:55:48] <JT_Shop> I'm jealous about the VF1
[16:55:57] <WalterN> heh
[17:32:24] <_DJ_> gn8
[17:54:11] <Jymmm> If you /join #hackvana and we get 100 people, he'll youtube a hamsterdance! It's about hobby PCB's. you can just lurk if you like
[17:54:50] <WalterN> heh
[17:55:09] <WalterN> just mentioning lurking in a new IRC channel should be tempting for most everyone
[17:55:49] <alex_joni> at 93 now
[17:55:51] <Jymmm> Hamsterdance for all!!!
[17:56:20] <Jymmm> Yeah, just need 100 (7 more)
[17:57:53] <Jymmm> hey alex_joni
[18:30:46] <Jymmm> Thanks all, we got 100 in #hackvana for our hamsterdance!!!
[19:03:00] <Valen> w00t
[19:54:30] <PetefromTn> Happy Halloween Everyone!!
[20:49:07] <MacGalempsy> mesa 5i25 - pullups, enable or disable?
[21:02:46] <pcw_home> Dont change
[21:07:12] <MacGalempsy> what about stuff on the servo amps that have HI, LO
[21:07:39] <MacGalempsy> and three wire endstops?
[21:09:01] <MacGalempsy> nevermind, I think I see it
[21:09:27] <pcw_home> I would probably just jumper so the drive is happy
[21:09:55] <pcw_home> you really only need drive enable
[21:10:34] <MacGalempsy> fault enable and reset, I think I want those to have check lights in linuxcnc,
[21:10:55] <MacGalempsy> ill try default, and see if I can get it to work
