13:00 Hukka hi
13:01 promet30 hi Hukka
13:01 Hukka hi promet30
13:04 promet30 hi billmania
13:05 promet30 Hakku: are you a robot builder?
13:08 Hakku Not really
13:08 robotustra :)
13:08 promet30 :)
13:29 billmania promet30: Hello.
15:16 poli Good afternoon everyone!
19:22 GuShH rue_house: have you tried FreeCAD?, so far I like it a lot (it's very similar to SolidWorks in fact)
19:23 GuShH Don't see any analysis options though
19:24 robotustra I study SW now
19:24 robotustra slowly slowly
19:24 robotustra is it parametric?
19:32 GuShH robotustra: yes
19:32 GuShH robotustra: it's a poor man's SW
19:33 GuShH I like it so far... everything works like it should
19:33 GuShH decided to watch some "tutorials" instead of reading the crappy docs http://freecad-tutorial.blogspot.com.ar/
19:33 GuShH I don't see any differences with SW so far
19:34 GuShH except SW has a lot of analytical tools and a powerful renderer...
19:34 GuShH (but design wise it's very similar, except for a few advanced options)
19:40 GuShH robotustra: ok one complaint is that there should be a better constraint helper
20:06 robotustra GuShH: try T-FLEX if you want something different from SW
20:06 GuShH robotustra: not cope manage? huh
20:06 robotustra not cope with
20:06 GuShH I told you, if you've got a full license for me, I'll try it
20:06 GuShH otherwise, beat it
20:06 robotustra there is a free ftudent version
20:06 robotustra student
20:07 GuShH which is useless
20:07 robotustra it's fully functional
20:07 robotustra why?
20:07 GuShH read the fine print.
20:10 robotustra the only restriction that you can't open saved files in fully licensed version
20:10 robotustra and cannot do some exports
20:11 robotustra I used student version for all my drawings for 2 years and it was ok
20:11 robotustra no problem
20:12 GuShH robotustra: no thanks
20:12 GuShH wait, 2 years and it still takes you several hours to draw a few parts?
20:14 robotustra GuShH: not everyday
20:14 robotustra it's nore powerful than SW that's why it take a bit longer than in SW
20:14 GuShH lawl such bullshit
20:15 robotustra ok, I'm just slowpoke
20:15 ShH hands robotustra a cup of co
20:15 GuShH now you are faster!
20:18 robotustra :)
20:18 robotustra my kids jumping on my knees
20:21 robotustra multitasking slow me down dramatically
20:25 GuShH robotustra: two kids?
20:25 robotustra yep
20:25 GuShH how did that happen!
20:26 GuShH two boys or one boy and one girl
20:26 robotustra two girls
20:26 GuShH holy shit
20:26 ShH pats robotu
20:26 robotustra yep, but they behave worser than boys
20:26 GuShH you should buy a gun now so when they're on their teens you'll be well prepared.
20:27 GuShH daddy here's my boyfriend *boom*
20:27 robotustra or big knife
20:27 GuShH lol
20:27 robotustra to cut off balls
20:27 GuShH you can shoot their balls off too
20:28 ShH enjoys his espr
20:29 GuShH added a bit of sugar to the milk before frothing, it really brings up the almond / nutty flavours of this blend
20:29 GuShH unless.... it's cyanide...
20:32 robotustra anyway
20:32 robotustra trackers, spycams, etc etc
20:32 robotustra it's my future
20:33 robotustra bugs
20:34 GuShH LOL
20:34 GuShH robotustra: better start saving then
20:38 robotustra no, I heve to get necessary for that experience untill that time
20:38 robotustra have
20:38 robotustra err
20:39 robotustra I have to get necessary experience to that time
20:39 robotustra dislexic
20:42 GuShH :o
20:49 robotustra I'm looking movie in parallel
20:50 GuShH oh?
20:50 GuShH i'm watching a video, learning FreeCAD and talking to robotrussia I mean robotustra.
20:51 robotustra I'm doing nothing
20:52 GuShH got the sink mount welded, bitched about the mask again... I'm almost convinced I'm going to buy the auto darkening one soon
20:52 GuShH oh and it rained, again. I hate this weather.
20:52 robotustra I have to redraw the head of robot
20:53 robotustra I don't like my first version
20:53 GuShH might even bite the bullet and get a generic chop saw...
20:53 robotustra it will be difficult to install PCBs in it
20:54 GuShH I think I can put it on the wood lathe stand (it has a shelf underneath) so it wouldn't take up space perse...
20:54 GuShH not sure what's the standard cutoff wheel "width"
20:54 GuShH 3mm?
20:58 GuShH they're 14" discs but it doesn't say how wide they are
21:02 robotustra are you talking to yourself?
21:02 GuShH asking to see if anyone who owns one knows what's the standard
21:02 GuShH to know how much material is wasted on every cut
21:03 robotustra I think more
21:03 robotustra about 4 mm
21:03 robotustra but there are different disks I think
21:03 GuShH see, with the angle grinder I can use 1mm, but I haven't been able to remove my shitty human pulse 100%
21:03 GuShH Of course there are different ones
21:03 GuShH but what's the absolute standard?
21:03 GuShH 4mm is quite thick, not terribly so... but thick nontheless!
21:06 robotustra use hacksaw
21:06 GuShH http://www.homedepot.com/p/DEWALT-14-in-Cut-Off-Saw-D28715/100634624#.Ud4Ppfm1FqI
21:06 GuShH of course I wouldn't buy dewalt, here they cost 4x
21:06 robotustra it will take only 1mm
21:06 GuShH robotustra: no thanks
21:06 GuShH even with a new blade and all the patience in the world, it can turn you gay.
21:07 GuShH it doesn't say what disc width it comes with?
21:07 GuShH http://www.homedepot.com/p/Diablo-14-in-x-1-8-in-x-1-in-Metal-High-Speed-Cut-Off-Disc-DBD140125A01F/202831053#.Ud4QFPm1FqI
21:07 GuShH that seems to be a standard one
21:08 robotustra when I was young I did a concrete mixer with hammer, chisel, hacksaw and welder
21:08 robotustra in 2 weeks from sheet metal
21:08 GuShH I've lost my patience long ago
21:08 robotustra :)
21:08 robotustra it's like meditation
21:09 GuShH so they're 3.175mm
21:09 GuShH ?
21:09 robotustra 1/8"
21:09 GuShH yes more or less 3.1mm
21:09 GuShH so I was more right than you?
21:09 robotustra yes
21:09 GuShH WINNING
21:10 GuShH where's theBear?
21:10 robotustra 1/8" = 3.175 mm
21:12 GuShH there's almost no price difference in the US when it comes to some DeWalt products...
21:13 GuShH why are they so expensive here!
21:13 GuShH 130 bucks for the cheapest generic chinese one, 179 for the dewalt on home depot US
21:14 robotustra I bought makita
21:15 GuShH here it's more like 140 bucks for the generic one, 250 for the dewalt
21:15 robotustra I used it only one time to cut rails for cnc mill
21:16 GuShH lol
21:16 robotustra rods are too hard for hacksaw
21:16 robotustra lol but it's true
21:16 GuShH I use the angle grinder a LOT but it's a pain to dress every cut so it ends up square and you end up wasting more than the 3mm this thing cuts
21:16 GuShH and the time...
21:17 GuShH I can't justify a dewalt though
21:17 robotustra make your stand 3 mm lower
21:17 GuShH ?
21:17 robotustra nm
21:17 GuShH No, I accounted for loss of material
21:17 GuShH I can waste over 10mm per cut in fact
21:17 GuShH I'm not -that- silly
21:17 robotustra I don't know how silly you are :)
21:18 GuShH hmm the makita one is 243 bucks
21:18 GuShH too expensive
21:18 GuShH it comes with 5 discs... heh
21:19 GuShH looks like the vise uses a cam-lock instead of an acme screw
21:19 GuShH so unlock, push, lock
21:20 GuShH anyway, too expensive...
21:20 GuShH robotustra: did your makita come with dust collection pickup?
21:22 robotustra no
21:22 robotustra just some disks
21:23 robotustra I used a bucket of water as dust collector
21:23 GuShH found a cheaper makita (another store) 229 bucks.. still expensive
21:24 GuShH that's the thing, for something you won't be using all the time, is it worth thinking about these brands at all...
21:25 GuShH (makita, bosch, dewalt...)
21:25 robotustra I'm telling you, I would already cut all your stuff with hack saw
21:25 robotustra while you are talking here
21:25 GuShH over 50 cuts in total?
21:26 GuShH doubtful.
21:26 robotustra and what?
21:26 GuShH I already cut half, still unhappy
21:26 robotustra I cut 5"x3/4" of aluminum in 1 hour
21:26 GuShH And I told you I'm not full on working on that thing every day all the time
21:26 GuShH is that your best time?
21:26 robotustra I did a lot of cuts while doing my cncn mill
21:26 GuShH do you race against other people?
21:26 GuShH lol
21:27 robotustra no, I'm just telling you, that it's no so difficult as you think
21:28 robotustra sharp hack saw do miracles
21:28 GuShH who said it was difficult
21:28 GuShH I said I have no patience
21:28 GuShH and a bad back
21:28 GuShH which worsens my lack of patience by a factor of 10
21:28 GuShH also I like accuracy
21:30 MrCurious anyone in san diego have a EasyDriver stepper driver board they would be willing to part with?
21:31 MrCurious suppose i should look for a avr + 4 stepper driver board
21:40 GuShH MrCurious: what did you burn now?
21:41 MrCurious and EasyDriver
21:41 MrCurious wish i had a 4 stepper driver with avr on board
21:43 robotustra he heed 1 byte controller
21:43 robotustra need
21:43 robotustra and he choose AVR
21:43 MrCurious https://www.sparkfun.com/products/10507
21:43 MrCurious debating switching to that
21:44 MrCurious thinking this would GREATLY simplify the design
21:44 MrCurious and be here in less than a week
21:45 robotustra 2A I thing it's not enough for your aluminium giant
21:47 MrCurious Each EasyDriver can drive up to about 750mA per phase of a bi-polar stepper motor.
21:47 MrCurious more than what i am using
21:48 MrCurious they have been pulling 13v1.6A for 4 motors in motion
21:50 robotustra I would have a reserve at least 2 times
21:50 MrCurious if i do that, it will be HUGE, like for a real cnc
21:51 robotustra do it do it do it now
21:51 robotustra that song can't came out of my head
21:51 GuShH can't find parts libraries for FreeCAD... hmm
21:51 GuShH maybe they have another name
21:52 robotustra yep, FreakCAD
21:52 GuShH ...
21:52 robotustra :)
21:52 GuShH I mean parts like screws, nuts...
21:52 GuShH bearings
21:52 GuShH all the standard objects
21:53 GuShH so I don't have to make them myself
21:53 GuShH including common steel sizes....
21:53 robotustra do you think somebody already did it for you?
21:54 robotustra I thought it's kind of "do it yourself" software
21:54 GuShH well eagle has a free version
21:54 GuShH and people make libraries all the time for it
21:55 robotustra Eagle is made by big serious company
21:55 GuShH not so serious.
21:55 GuShH size of company is irrelevant
21:55 robotustra anyway, people are too lasy to finish free products
21:55 GuShH look at the standard libraries on LTSpiceIV
21:55 GuShH they suck
21:56 ShH eyer
21:56 robotustra I don't blame free software, I like it
21:56 GuShH robotustra: so which libraries come with your t-flex
21:56 GuShH seems you are a bit of a titflex fanboy
21:56 GuShH sorry, t-flex.
21:57 robotustra the company did ithis libraries
21:57 robotustra standart elements
21:57 GuShH are they all under russian standards?
21:57 robotustra yes
21:57 robotustra GOST
21:57 GuShH RUSSIAN SCREW NUMBER 2, STRONG.
21:57 GuShH IF NO FIT, USE HAMMER.
21:58 GuShH OTHERWISE, LET HAMMER USE YOU.
21:58 robotustra you are so naif
21:58 GuShH naive? not sure what's naif
21:58 GuShH It's all good fun, nothing personal.
21:58 robotustra ask rue what does it mean :)
21:58 GuShH I don't know if he's around
21:59 GuShH adj. "variants of naive" nonsense, who made this up?
21:59 robotustra you think that first rocket for Korolev was made by bears
21:59 GuShH Strong bears, vodka and hammers.
22:00 GuShH in no particular order.
22:00 GuShH I crashed FreeCAD..
22:01 Tom_itx is that hard to do?
22:01 GuShH I just clicked on "part design" from the welcome menu
22:01 robotustra SW hanged my notebook today
22:02 GuShH Yes I've crashed SW in the past
22:02 robotustra but I think it was just overheating
22:02 GuShH But I don't use it anymore
22:02 GuShH robotustra: do you have any perspective cad drawing (with dimensions) handy so I can practice on FreeCAD?
22:03 GuShH dang, how do you make a thread in FreeCAD...
22:04 robotustra I didn't use Freecad
22:05 GuShH see, there should be a library
22:05 GuShH why should I fool around with the helix object and whatnot...
22:05 robotustra I thought it's not finished yet to stage I can use it
22:05 GuShH pfft
22:06 robotustra tell me if I wrong
22:07 GuShH if I could find libraries (or whatever they're called) I'd argue your point
22:07 GuShH maybe I should be looking for macros or scripts instead
22:10 robotustra you are contraversal, from one point of view you have patience to find a library, but from other side - you don't have it
22:10 GuShH sue me
22:11 e4016 sends GuShH a sub-p
22:11 robotustra I think that to move electrons is 1938 times easier that to move atoms
22:13 GuShH I need more RAM...
22:30 ace4016 robotustra, depends on the atom :P
22:31 ace4016 electrons don't like to leave their energy levels too much...and atoms have different masses
22:41 robotustra ace4016: it was lust an ugly joke :)
22:44 robotustra ace4016: did you ever heared about free electrons?
22:44 robotustra 1938 - it's just the ratio of masses of electron and neutron
22:45 robotustra 1936 = m_p/m_e
