[01:35:26] <thesaint> feeds and speeds calculator - any recommendations?
[01:35:36] <thesaint> turning..
[01:35:37] <PetefromTn_> fswizard
[01:35:59] <thesaint> ok, cool.. free?
[01:40:20] <PetefromTn_> yeah online it is
[01:42:56] <zeeshan> rpm = 4 * cs / d
[01:43:05] <zeeshan> feed = # teeth * rpm * chip load
[01:43:10] <zeeshan> thats all :P
[01:43:17] <XXCoder> fswizard adjusts it a little based on brand tools I think
[01:43:25] <XXCoder> in least their paid version do?
[01:43:38] <zeeshan> i find it's not accurate
[01:43:41] <XXCoder> zeeshan: check this out https://youtu.be/oF0pMILT7_Y
[01:43:48] <zeeshan> when you actually open the pdf, and put in the sfm, chip load values yourself
[01:44:05] <XXCoder> fs wizard dont allow me to lock rpm :(
[01:44:18] <zeeshan> you can
[01:44:20] <XXCoder> because mine is 27k rpm period
[01:44:22] <zeeshan> you can type max rpm
[01:44:33] <XXCoder> but no miniu,m
[01:45:12] * XXCoder wonders if that same machine can cut wax
[01:50:19] <XXCoder> checked it again zeeshan nope still no min rpm
[01:53:49] <Tom_itx> fswizzard has a phone app too
[01:54:17] <XXCoder> yeah saw it

[02:18:17] <thesaint> XXCoder, what sort of spindle do you have on your mill that does 27k?
[02:18:26] <XXCoder> grinder
[02:18:35] <thesaint> work ok?
[02:18:50] <XXCoder> havent ran whole machine yet as still no room in garage
[02:20:49] <thesaint> XXCoder, well have fun when you do :-)
[02:20:57] <XXCoder> I cant wait.
[02:21:08] <XXCoder> one of my plans is to cast soft metals
[02:21:09] <thesaint> much more to go?
[02:21:14] <thesaint> ok..
[02:21:25] <XXCoder> nah need to move machine, setup walls so chips dont go everywhere
[02:21:37] <XXCoder> then install "spindle" and T it
[02:21:45] <thesaint> chips always go everywhere... lol
[02:21:47] <XXCoder> then its basically ready
[02:22:02] <XXCoder> I know, just dont want EVERYWHERE just everywhere. lol
[02:22:19] <XXCoder> \I dont wanna find chips mile away ;)
[02:22:19] <thesaint> lol...
[02:22:57] <thesaint> night guys, hitting the sack! cheers...
[02:23:04] <XXCoder> dont let sack hit you
[02:23:06] <XXCoder> night

[07:24:55] <anomynous> what is the point of cinnamon? Im looking at debian live images
[07:25:07] <anomynous> why they diverged from gnome?
[07:25:26] <XXCoder> dunno but I wouldnt use gnome, nor kde. I like xfce
[07:25:39] <XXCoder> expecially the 4.x one
[07:25:59] <anomynous> ive been using xfce, but im curious about cinnamon now
[07:25:59] <anomynous> :D
[07:26:44] <anomynous> also mate desktop ive never heard about
[07:27:29] <XXCoder> cinnamon if I recall right, is fork of gnome, but classic one
[07:27:35] <XXCoder> so quite lean compared to gnome
[07:27:44] <XXCoder> could be wrong though
[07:28:42] <archivist> witnit, it is fun watching an axis follow another :)
[07:29:41] <cmorley> cinnamon is a modern coded version of a blend of old desktop and new desktop styles. most people who do real work, don't really like Gnome diesktop
[07:29:59] <anomynous> never used gnome3 much
[07:30:53] <cmorley> Mate is a fork of GTK2 desktop similar idea of cinnamon but even more like the old desktop
[07:31:00] <archivist> I am just fed up with people futzing with UIs
[07:31:02] <anomynous> mm
[07:31:08] <anomynous> cinnamon sounds cooler
[07:31:09] <anomynous> :D
[07:31:12] <anomynous> ill try that
[07:31:21] <cmorley> blame Gnome and Ubuntu
[07:31:31] <anomynous> i dont blame. To each their own

[07:51:02] <anomynous> archivist, futzing? I havent used a linux desktop in a long time and cinnamon and mate are something ive never heard of ;D I wanted to try one. I prefer having a desktop over console, after all.
[07:51:05] <witnit> the only problem with various desktops and GUI is that they dont each swap with another and smoothly transition without disturbing some other aspect of the environment. IMO many desktop environments simply root too deep into the rest of the operating system for my liking
[07:51:59] <XXCoder> thats why I like xfce better
[07:52:04] <witnit> ^
[07:52:08] <XXCoder> more seperation.
[07:52:18] <witnit> thats been my opinion about it
[07:52:28] <anomynous> anything that labels itself as window manager instead of a desktop environment?
[07:52:31] <anomynous> :D
[07:52:32] <witnit> once it is refined a bit, it will be better i believe
[07:52:34] <archivist> I had to help a user on win8, how did that get out the door!
[07:53:25] <archivist> shite where you have to make gestures....
[07:55:00] <witnit> things such as file association and menu items should all be systemwide regardless of windowmanager or enviroments. it seems often those get broke if they are ever customized
[07:55:06] <anomynous> witnit, never thought of it like that. For me the desktop environment has been mostly a way to handle windows and have icons for things and have virtual desktops.
[07:55:07] <archivist> fading and transparency, just wastes processor cycles and slows things down
[07:56:01] <XXCoder> wooby windows lol
[07:56:18] <XXCoder> linux do have that, but lukcly easy to disable (its disabled by default)
[07:58:41] <witnit> well for what its worth i believe most of us prefer a simple system for our machines with seamless upgrades and problem free transitions to new and unusual hardware (like a different mainboad, network card, or video card)
[07:59:00] <XXCoder> and a system where compoments are swappable
[07:59:03] <XXCoder> linux isnt like that now
[07:59:31] <archivist> bling has no place on a working PC
[07:59:43] <anomynous> witnit, file associations should be system wide? How is that? No they shouldnt! :D
[07:59:50] <witnit> scalability of modular components, both hardware and software are rather important too
[08:00:00] <XXCoder> archivist: changable compoments is not always bling
[08:00:05] <anomynous> you should know what you wanna do with the file and type command filename :D
[08:00:21] <anomynous> the association is system wide in your head
[08:00:38] <XXCoder> for example if I want better file manager I should be able to just install and change setting. xfce does allow that, though not perfectly working.
[08:00:54] <witnit> well if they are preset in xfce and i install kde, kde should be like, ahhhh got it, you prefer OKULAR for pdfs
[08:01:08] <witnit> is all im saying
[08:01:25] <anomynous> no they shouldnt
[08:01:27] <anomynous> :D
[08:01:31] <anomynous> sounds too complicated
[08:01:32] <archivist> I prefer PDF to die
[08:02:25] <XXCoder> pdf is good standard for documents
[08:02:26] <witnit> im glad we ditched gnome as a distro standard
[08:02:28] <XXCoder> not books and so on
[08:02:39] <archivist> XXCoder, not for image scanned docs
[08:02:45] <XXCoder> indeed.
[08:03:10] <archivist> it is a terrible standard to look inside to get data as well
[08:03:59] <witnit> eventually we will be able to do an X-ray on an entire old book while its still closed and convert it to a text document
[08:04:34] <XXCoder> wont happen
[08:04:36] <archivist> scanning is effin hard work
[08:04:41] <witnit> could happen
[08:04:44] <XXCoder> unless ink was some form of metal.
[08:04:49] <archivist> fold out diagrams!
[08:05:01] <XXCoder> paper and ink is equally transparent to xray
[08:05:11] <XXCoder> archivist: you remember book scanner I linked to
[08:05:20] <XXCoder> I cant wait to get mine! should be fairly soon now.
[08:05:21] <witnit> maybe the paper hold a different density where the ink lies

[08:05:35] <archivist> XXCoder, no
[08:05:41] <Deejay> moin
[08:05:43] <witnit> and you could use harmonics to measure the paper
[08:05:46] <witnit> mojn!
[08:06:03] <XXCoder> https://www.indiegogo.com/projects/czur-scanner-build-your-own-digital-library#\
[08:06:04] <Deejay> hoi witnit
[08:06:09] <witnit> depth penetrating harmonic imaging
[08:06:10] <witnit> lel
[08:06:25] <witnit> sounds like a thing
[08:06:35] <XXCoder> invent superman xray then as it's not same as actual xray lol
[08:06:47] <XXCoder> he probably can control how "deep" he views
[08:07:14] <archivist> https://www.indiegogo.com a broken website useless
[08:07:27] <XXCoder> oopd
[08:07:31] <XXCoder> https://www.indiegogo.com/projects/czur-scanner-build-your-own-digital-library#/
[08:09:21] <archivist> XXCoder, I mean broken http://www.collection.archivist.info/archive/grabs/Screenshot-32.png
[08:10:07] <XXCoder> interesting. noscript?
[08:10:34] <archivist> nope
[08:11:19] <witnit> nice
[08:11:32] <XXCoder> that looks like firefox, I use that too
[08:12:08] <XXCoder> one of your plugins may be inferening as I see couple unknown icons
[08:12:17] <witnit> archivist: https://youtu.be/WZLSCyXFUxk
[08:12:20] <archivist> they use 100 resources and 5.27 mb to do so little
[08:12:21] <witnit> this is the video from there
[08:12:38] <XXCoder> witnit: yeah its pretty amazing, should get it next month
[08:13:40] <archivist> camera above is an old idea
[08:14:02] <XXCoder> it is, but its convient package
[08:14:08] <XXCoder> I took foot pedal option too
[08:14:09] <witnit> the money is in the fact they streamlined it and anyone can use it, I would assume genealogy forums or librarians types would take it for a big hit
[08:14:11] <XXCoder> so both hands free
[08:14:37] <XXCoder> theres also special button thingy I got since I shared on fb lol
[08:15:07] <witnit> ntm automatic cropping and high speed collaboration, people will buy it foooo shooo
[08:15:56] <archivist> wont deal with fold outs, limited field
[08:16:26] <witnit> anyone got pick and place with video working yet?
[08:17:26] <anomynous> aaa
[08:17:31] <anomynous> how much you paid for the scanner
[08:17:44] <XXCoder> 200
[08:17:52] <archivist> ouch
[08:18:00] <anomynous> does ocr work well?
[08:18:20] <XXCoder> unknown, hopefully lol
[08:18:24] <anomynous> ;D
[08:18:31] <XXCoder> its indiegogo. always a risk.
[08:18:39] <anomynous> let me know how you like it
[08:18:42] <XXCoder> sure.
[08:21:01] <anomynous> hopefully for foreign languages too :D image scanned pdfs are useless. You cant text search them
[08:21:29] <anomynous> i hate it when im looking for some houseld appliance manual and its a scanned image pdf :E They first write a manual and then wreck it
[08:21:58] <XXCoder> isnt there way to ocr pdf files?
[08:22:07] <XXCoder> or in least extract all pics and ocr em
[08:22:45] <anomynous> im supposed to look for a working ocr software to read a published manual? I just read it like actual book then, look for toc and flick pages
[08:22:53] <anomynous> and read where the thing is im looking for
[08:22:58] <anomynous> instead of ctrl+f
[08:22:58] <anomynous> :D

[08:29:00] <XXCoder> archivist: theres pdfocr linux utility
[08:29:12] <XXCoder> might try mass convert and check if nice or messy
[08:29:34] <archivist> you always have to hand edit the output
[08:33:58] <archivist> and OCR that http://www.collection.archivist.info/diva/systrondonner1626.html#p=127&z=1

[10:24:48] <XXCoder> nice
[10:24:56] <XXCoder> I wonder how buildable a cmm is
[10:25:04] <XXCoder> extudes and all that
[10:26:19] <archivist> why build if cheap enough on ebay
[10:26:28] <XXCoder> for lols? heh
[10:26:42] <XXCoder> true though
[10:27:16] <archivist> you will have a far better starting point, servo, proper scales etc
[10:28:20] -!- DaPeace has quit [Ping timeout: 255 seconds]
[10:33:02] <XXCoder> yeah
[10:33:06] <XXCoder> though what software?
[10:33:31] <archivist> there is a bit of probing in linuxcnc
[10:33:46] <archivist> not enough for a full cmm yet though
[10:33:53] <XXCoder> interesting
[10:34:04] <XXCoder> lol
[10:34:10] <XXCoder> single cmm calibration sphere
[10:34:18] <XXCoder> 354 bucks
[10:34:26] <XXCoder> looks like tow ball
[10:34:30] <archivist> they are not cheap
[10:34:40] <XXCoder> only 100 times more accure I bet
[10:35:49] <archivist> I cheated and used a probe stylus upside down as my datum ball
[10:36:37] <XXCoder> not bad as sphere there should be quite accurate
[10:36:39] <XXCoder> and precise
[10:39:01] <archivist> https://www.youtube.com/watch?v=8XIscw-ciEg
[10:41:37] <SpeedEvil> Can't you just use a tow-ball, and rotate it?
[10:41:59] <SpeedEvil> I guess calibration would be more complex if you have to derive the shape
[10:42:06] <archivist> it is used for calibration
[10:42:33] <archivist> so is supposed to be better than gnats cock
[10:42:54] <XXCoder> yeah
[10:43:03] <XXCoder> cant calbrate with unknown shape
[10:43:32] <XXCoder> towball is "sphere" to us but it sure isnt smooth near-mathically perfect sphere to it
[10:43:55] <SpeedEvil> I gues you can't calibrate distance, but surely you can - with rotating it into several positions - eliminate any uncertainties in the shape?
[10:44:07] <XXCoder> reminds me of new silican Kg sphere. its so sphereic that if it was size of earth, tallest mountain would be inches tall.
[10:44:08] <SpeedEvil> Or do you actually need a sphere for some reason
[10:44:43] <archivist> you come at it from various directions to measure the error in the probe
[10:45:00] <SpeedEvil> ah - so it'd be a _lot_ more work
[10:45:15] <archivist> so you tell the software what the diameter is and then it works out the errors
[10:45:58] <XXCoder> heh precision paradox - you need accurate test to ensure its accurate
[10:46:08] <archivist> :)
[10:46:27] <XXCoder> I guess it was via methods that does NOT need accurate thing, like that weight balance thing, which can be very accurate by visual
[10:46:33] <anomynous> XXCoder, the one that is supposed to be new definition of kilogram in # of atoms?
[10:46:38] <XXCoder> indeed anon
[10:47:18] <XXCoder> its still physical, but in least this time it can be recreated as orginial Kg drafts in weight
[10:47:27] <XXCoder> none of Kg weights agree with each other now
[10:47:38] <XXCoder> cause is still unknown
[10:47:50] <anomynous> europe > usa. Proof: Pounds is defined as kilograms. You just mimic us! :D
[10:48:00] <archivist> corrosion adds weight :)
[10:48:12] <XXCoder> I wish imperial units die now
[10:48:15] <XXCoder> archivist: nope
[10:48:27] <XXCoder> its inside vaccum contain inside vacuum contain
[10:48:32] <XXCoder> so yeah zero chance
[10:48:40] <archivist> XXCoder, it does, eg iron to iron oxide
[10:48:45] <anomynous> you live in uk, XXCoder, right?
[10:48:50] <anomynous> dont you use imperials?
[10:48:53] <XXCoder> no oxygen archivist
[10:49:17] <XXCoder> vacuum container, which is entirely placed inside ANOTHER vacuum container
[10:49:18] <archivist> pure vacuum is also a dream
[10:49:37] <XXCoder> doubvle vacuum makes it largely proof from inrusion

[10:50:08] <archivist> largely is not = to totally immune
[10:50:12] <XXCoder> I know.
[10:50:16] <anomynous> so you were just being sarcastic funny by saying i hope they die
[10:50:17] <anomynous> :D
[10:50:17] <XXCoder> but tests show it was all good
[10:50:34] <XXCoder> anomynous: nope. I want imperial system to die. I hate foot, inches so on
[10:50:39] <XXCoder> I prefer meteric system
[10:50:43] <archivist> I am in UK and use both unit systems :)
[10:50:54] <anomynous> why
[10:51:03] <XXCoder> 5,632 foot in mile.
[10:51:07] <XXCoder> 12 inches in foot
[10:51:36] <archivist> because there is plenty of older stuff still in use
[10:51:37] <XXCoder> 3 feet in imperial meter
[10:51:43] <XXCoder> archivist: that does make sense
[10:51:50] <XXCoder> but its time to end new imperial stuff
[10:51:56] <XXCoder> imperial sized
[10:55:43] <XXCoder> anomynous: I mean, what size is 5/16? it takes bit of thinking more than simple mms and decimal. though there is one postive
[10:55:58] <XXCoder> it allows something like 3/10 which has infinite decaimal digits
[10:56:29] <archivist> 1/3 of a mm is also infinite!
[10:56:51] <anomynous> but theres no such size wrench
[10:56:53] <anomynous> :D
[10:56:54] <archivist> changing system does not get rid of that problem
[10:56:55] <XXCoder> indeed but from what i understand meteric dont use fractions in most size
[10:56:57] <XXCoder> indeed!
[10:57:09] <archivist> pi
[10:57:15] <XXCoder> archivist: no, but then no 1/3 wrench
[10:57:19] <XXCoder> 5/16
[10:57:20] <XXCoder> so on
[10:57:22] <anomynous> i cant tell what size it is from just looking at sizes. I need to convert it to metric
[10:57:25] <anomynous> :D
[10:57:50] <anomynous> is 5/16 bigger than 3/8?
[10:58:20] <XXCoder> nope
[10:58:25] <XXCoder> took me a second
[10:58:31] <anomynous> but you have to calculate it
[10:58:35] <archivist> XXCoder, someone is likely to want a 3rd of a metre
[10:58:43] <XXCoder> tip, just 2x top and bottom of second one
[10:58:55] <XXCoder> it has 16, you can then directly compare 5 to 6
[10:59:03] <XXCoder> but yes had to calculate
[11:02:16] <XXCoder> theres $15 cmm metric test sphere
[11:02:23] <XXCoder> dunno accuracy lol
[11:02:42] <XXCoder> http://www.ebay.com/itm/Standard-CMM-Tooling-Ball-/321182168222?hash=item4ac7f2f49e:g:y04AAOxySOlSBQYv
[11:05:30] <MrSunshine> torque vs microstepping, is 4 microstepping higher total torque than 8 microsteps or will it be the same in the end
[11:05:44] <MrSunshine> like step 1 is same as 1 on 8 microsteps, step 2 is same as 4 on 8 microsteps etc ?
[11:08:08] <archivist> XXCoder, that sort of ball is a kinematic mount rather than a datum ball

[11:09:51] <archivist> MrSunshine, due to the magnetics you will get a shock when you see angle v command when using many microsteps
[11:11:12] <XXCoder> archivist: whats kinematic and datum though latter I can guess - reference shape or data?
[11:11:21] <MrSunshine> archivist: what do you mean ?
[11:12:26] <archivist> MrSunshine, http://www.archivist.info/cnc/wormtest/plot_normalisedb.php
[11:12:42] <archivist> this is a commanded angle error plot
[11:13:22] <XXCoder> interesting
[11:13:33] <XXCoder> .01 mm I assume?
[11:13:41] <XXCoder> because if inches thats huge error lol
[11:13:42] <archivist> degrees
[11:13:46] <XXCoder> ahh degree
[11:14:57] <archivist> there is a high res plots somewhere, lots to finish on that project
[11:21:33] <archivist> MrSunshine, what I have written so far http://www.archivist.info/cnc/wormtest/
[11:21:59] <archivist> I have not pulled out the microstepping error properly yet
[11:25:41] <Sync> with a regular servo or a feedbacked stepper driver that would go away
[11:27:36] <archivist> I know that but all the microstep wannabes are dreaming of extra accuracy :)

[11:30:17] <MrSunshine> archivist: im dreaming of smooth motion
[11:30:23] <MrSunshine> not realy extra accuracy =)
[11:31:55] <archivist> I ran a large stepper on 8 microsteps and the magnetic error really affects it
[11:33:02] <MrSunshine> ive been running 5 microsteps on the drivers now and it has worked quite well
[11:33:05] <Sync> yeah, it is pretty useless without feedback
[11:33:22] <MrSunshine> most often within about 0.05mm of target dimensions without cutter compensations
[11:34:05] <Sync> hm, I should get one of those heidenhain angular measurement devices and take some measurements on the lehmann rotary I have
[11:34:44] <archivist> I just use an encoder to measure angle
[11:37:02] <archivist> see last image for the rotary test http://www.collection.archivist.info/searchv13.php?searchstr=wormtest

[17:33:58] <miss0r> I just did some facemilling with a 80mm flycutter. And it seems I am unabled to make the overlapping of the two passes perfect. I did some measuering with my dial, and across the flycutter path I have 0.03mm level difference. I am thinking this is caused by the Z axis not being perfectly aligned. Do you guys know of a surefire way to measure the inacuracy of the z axis angle vs. the table?
[17:33:59] <miss0r> I do some 'some' adjustment possibilities.
[17:35:29] <SpeedEvil> miss0r: have you considered simpe spring?
[17:35:54] <miss0r> simpe spring?
[17:36:29] <SpeedEvil> Simple
[17:36:45] <SpeedEvil> I mean - it's not due to flexing with the fly cutters torque/cutting forces?
[17:37:45] <miss0r> ahh.. I am fairly certain it is not. it sounds correct when cutting. also; it's a quite massive indexable knifehead with room for 4 inserts, I just only run with one
[17:38:12] <miss0r> so it's sortof a flycutter :)
[17:39:40] <SpeedEvil> I don't mean flexing of the fly-cutter, but flexing of the machine
[17:40:50] <miss0r> well. everything is possible. but it it also quite possible that the machine is out of alignment. I have had that feeling for quite some time. Mostly due to me being forced to take it apart when I bought it home way back in time. So any factory alignment would be gone.
[17:46:18] <Loetmichel2> SpeedEvil: flycutters have near negligble forces
[17:46:27] <Loetmichel2> ther IS no machine flexing at all
[17:46:41] <SpeedEvil> thanks
[17:47:55] <Loetmichel2> miss0r:get a bar of 15mm stock aluminium
[17:48:20] <Loetmichel2> a bit more than half as long as your table depth
[17:48:31] <Loetmichel2> drill two holes at the ends
[17:49:12] * miss0r is all ears
[17:49:15] <Loetmichel2> one with the diameter of your dial one with a diameter fitting dfor a drill bit or round stock you have that fits your collet
[17:49:15] <beikeland> Seems my assement was wrong; it is only the usb keyboard that hangs when trying to install. I just never had the mouse connected till now.
[17:50:24] <Loetmichel2> then glue clamp the drill bit and the micrometer dial in your bar, clamp the drill bit end into your macines colled and rotatet the spindle by hand and measure the table
[17:50:39] <Loetmichel2> once the dial shows the same height everywhere your spindle is level
[17:50:52] <Loetmichel2> assuming your table is level of course
[17:50:56] <miss0r> ahh. excelent idea
[17:51:22] <miss0r> well.. I have 3 t-slots along the length of the table. BUT I will place some parralel bars and see where it goes.

[17:58:06] <archivist> miss0r, the operation of fixing is called tramming http://www.cnccookbook.com/CCMillTramming.html
[17:58:38] <Loetmichel2> miss0r: the cheap variant of that is a sharpie fitted into the flycutter holder, let be rotatting slowly and then adjust the z axis angles until it makes a complete circle the moment it touches the table
[17:59:52] <miss0r> Loetmichel2: indeed. at the moment I am ~0.03mm off over a distance of 80mm. I'm not sure I can improve it with a sharpie :)
[18:00:16] <miss0r> archivist: yes. thank you. I just found a youtube video showing something like that
[18:00:23] <Loetmichel2> i have done 5/1000 on 150mm with a sharpie ;)
[18:00:25] <archivist> dti is best then you know the error
[18:00:55] <miss0r> Loetmichel2: Then I take back my words :)
[18:01:34] <Loetmichel2> that takes a REAL flat and level table tho

[18:13:07] <PetefromTn_> looking forward to seeing if the Falcon 9 can land on the floating barge today. Should be cool!
[18:13:13] <thesaint> miss0r, you need to run a dail gauge across your table from the spindle and adjust accordingly...
[18:14:12] <thesaint> miss0r, look on you tube and start watching maching stuff, search for something like ẗramming your mill table..
[18:19:02] <beikeland> if you have t-slotted table of aluminium profiles, laying down a pane of glass/mirror was suggested to me, as the sections of t-slotted aluminum profiles made the measurements go zig-zag. helped me adjust it quite a bit; then milled the table flat when the spindle was true
[18:22:41] <thesaint> PetefromTn_, yes, that will be pretty cool..
[18:23:16] <PetefromTn_> yeah man hopefully it will be successful this time. It was awesome to see it land at the cape safely last time..
[18:23:46] <thesaint> there is some exciting space vehicle stuff starting to happen now..
[18:24:04] <PetefromTn_> it's been happening for awhile now
[18:24:26] <PetefromTn_> they tested the SR25 rocket system not too long ago again for the SLS
[18:25:07] <PetefromTn_> RS25
[18:26:47] <thesaint> pity the virgin vehicle blew up..
[18:28:03] <PetefromTn_> the amazon rocket successfully landed too recently and they are testing the smaller version of the space shuttle as well. can't remeber the name of it. The heavy lift models of the Falcon 9 are starting to be worked on too apparently.

[18:29:22] <PetefromTn_> If we can get back to florida I want to take my kids to visit the cape they have never been there.
[18:29:49] <thesaint> actually that was pretty fucking awesome, the amazon rocket landing.
[18:31:19] <PetefromTn_> I thought so too... its apparently not nearly as big or powerful as the Falcon 9 but still very impressive
[18:32:27] <thesaint> and now over to my little schaublin 70 lathe for some finishing off :-)
[18:37:15] <Sync> PetefromTn_: well, I don't think it is a smart idea
[18:37:22] <Sync> it is neat and a technical feat
[18:37:29] <Sync> but I don't think it will be reliable

[18:55:43] <Loetmichel2> meh. no rockets impacting and exploding on droneships. Video link failure... "yeah, sure!" ;)
[18:58:09] <Jymmm> PetefromTn_: You know the space program was just shot in a giant warehouse and now know as amazon distribution center http://graphics.portwest.com/wp-content/uploads/2014/03/Warehouse-interior.jpg

[19:00:50] <Jymmm> I'm not watching anything
[19:01:42] <Jymmm> PetefromTn_: just teasing you a bit is all, and trying to learn this SDK
[19:01:59] <PetefromTn_> SDK?
[19:02:23] <Jymmm> A wifi module
[19:02:42] <Jymmm> SDK = Software Development Kit
[19:02:49] <PetefromTn_> ah
[19:04:13] <enleth> PetefromTn_: friend's comment upon seeing the SpaceX live stream: "oh, I see the graphics improved in Kerbal Space Program"
[19:04:23] <Jymmm> Couldn't figure out what the issue was originally. Then saw thedata sheet for my USB2TTL adapter is limited to 9ma@3.3v so had to add a 3.3v PS, and now sending it AT commands =)
[19:05:14] <Jymmm> You gotta love chinglish documentation... NOT!

[19:08:14] <PetefromTn_> Can ya hear me Major tom? ;)
[19:08:19] <Jymmm> 4 stories indoors!
[19:08:30] <Jymmm> You could even make an awesome waterslide!!!
[19:09:28] <Jymmm> You could CNC build a house, then transport it elsewhere,
[19:09:42] <maxcnc> why not build at place
[19:09:55] <maxcnc> cnc mashine is less weight
[19:09:58] <Jymmm> I really like those that the storage container IS the house, and the walls are stored inside of it for shipping.
[19:11:14] <Jymmm> maxcnc: too much waste and built together walls are awesome =)
[19:11:23] <Jymmm> bolt togther*
[19:11:52] <maxcnc> there are robots that build from scratch housings

[19:13:30] <Jymmm> then those robots aren't setup properly imo
[19:14:00] <Jymmm> I think alot has to do with building inspectors not "getting it", thne failing something
[19:26:28] <CaptHindsight> it's about protecting tradesmen
[19:27:07] <CaptHindsight> but all the union breaking going on maybe prefab will become more popular
[19:27:26] <Jymmm> breaking points?
[19:27:57] <CaptHindsight> getting rid of unions
[19:28:02] <Jymmm> ah
[19:28:41] <Jymmm> Unless it's LITERALLY a single item, I never use self-checkout.
[19:29:46] <CaptHindsight> I like how self checkout treats you like a suspected criminal
[19:29:56] <Jymmm> oh, the scale?
[19:30:07] <CaptHindsight> so it's slower than using a checker/cashier
[19:30:45] <CaptHindsight> the scale and the sensors, you have to have an item clear the belt before adding another item to it
[19:31:00] <maxcnc> have a nice sunday im off coudt not find how to search git for infile lines

[19:31:22] <Jymmm> CaptHindsight: I've never seen a belt in self-checkout,
[19:31:31] <Jymmm> like home depot
[19:31:47] <Jymmm> or grocery
[19:32:00] <CaptHindsight> most of the ones I have used have a belt
[19:32:34] <CaptHindsight> the small stations don't have a belt and they have issues as well with small or light items
[19:33:00] <CaptHindsight> or if you shift items around once they are in a bag
[19:34:40] <CaptHindsight> designed by criminals for criminals
[19:34:53] <Jymmm> lol
[19:35:08] <pcw_home> I always get "unexpected item in checkout area" on those so I have given up
[19:35:40] <CaptHindsight> I stare back at the person guarding the self checkout with suspicion
[19:35:44] <pcw_home> plus some local ones here were hacked to steal credit card info

[19:37:12] <CaptHindsight> they wish we all had implanted chips, it would make their lives easier
