00:09 RifRaf how micro?
00:12 Jak_o_Shadows 9g
00:12 MrCurious micro enough to flip range lenses down on your glasses while flipping reading lenses up...
00:12 MrCurious for a steam punk bi-focal
00:13 RifRaf yep, am using 3 of them for each eyeball at moment
00:13 Jak_o_Shadows Made http://imagebin.org/264573
00:14 RifRaf nice, any jitter?
00:15 Jak_o_Shadows So far, not at non-extreme positions
00:16 Jak_o_Shadows Also, I really need to do a delay, I can overwhelm the chips serial I think, if i go too fast
00:17 Jak_o_Shadows Now I just need to make teh arm lol
00:19 Jak_o_Shadows Also, loving getting lots of small zip-lock bags
00:21 RifRaf https://www.youtube.com/watch?v=WuLC0RcsIkw
00:22 Jak_o_Shadows oooh, that's clever
00:22 RifRaf yep i might try use some of the ideas in the mouth for my eyes
00:26 RifRaf Jak_o_Shadows, what size arm you making?, just with standard servos or the sg90
00:27 Jak_o_Shadows 10kg (MG996R) for the main joints, and the sg90 ones for the gripper
00:27 RifRaf am looking forward to making my next arm now that i can print lightweight gears and brackets
00:28 RifRaf Jak_o_Shadows, ok cool, feel free to use any of the ideas i cam up with while making my last one, same servos etc
00:28 RifRaf can take some close up pics if you need
00:28 Jak_o_Shadows yeah.
00:28 Jak_o_Shadows Just roughing it out for now, will do better attachments of servos to arm lengths later
00:29 RifRaf yep start with a packet of paddlepop sticks, nice and fast testing
00:29 Jak_o_Shadows Yeah.
00:30 Jak_o_Shadows How have you attached servo arm to arm length, in general? magic 3d printing?
00:30 RifRaf didn't have the printer back then, i made and customised other brackets
00:30 Jak_o_Shadows ah, k
00:31 Jak_o_Shadows I should get some decent drillbits
00:31 RifRaf just started with acrylic arms that screwed to the servo horns
00:31 RifRaf and that arm would also have the holder for next servo
00:31 Jak_o_Shadows I've got plenty of this aluminium extrusion, so I was going to mostly use that.
00:33 RifRaf keep the weight as mimimal as you can, rigid joints and short arms
00:33 GuShH making a midget robot?
00:34 RifRaf well every bit longer you try make the arm stresses the servos out much more, you'll find the even mg995 are not as strong as they appear
00:37 RifRaf if you want the arm to do real stuff then use a bigger gear motor with encoder for the shoulder and elbow
00:48 Jak_o_Shadows Yeah, i've done the maths a few times, it drops off linearly with distaqnce
00:56 rue_house air muscle
01:14 Jak_o_Shadows Kicked over my box of salvaged components. Pushbuttons and resistors everywhere
02:38 Jak_o_Shadows I oughta get some servo extension leads
02:59 Jak_o_Shadows Power supply lacks the power I think. Also, how the heck do you do cabling on a robot arm?
03:33 RifRaf carefully
03:35 RifRaf i made a custom loom, so only one set of + and - are required, and however many signal cables, and plugged the servos into the loom, makes the wire mass alot tidier
03:40 Jak_o_Shadows Yeah, only one set of power makes sense.
03:40 Jak_o_Shadows Considering seeing what the cheapest, and smallest, DIP chip with enough power for SPI and a servo is
03:49 RifRaf and keep the servo leads generous at the motors, so it can turn properly, and use zip ties to tie them in stratigic ways
03:50 Jak_o_Shadows Did you buy servo extension cables, or make em?
03:50 RifRaf you'll soon find out where they want to get caught up
03:51 RifRaf made and bought, only have a few extensions on the lower servos that go direct to uC, used the loom idea for all the top ones and custom made it
04:05 RifRaf Jak_o_Shadows, as for power you will want a few amps per servo, and cabling to match, the sg90 will only use maybe 1A max
04:06 RifRaf used about 10A lead for the shared + and - wires, the signal cables can be as thin as you like
04:08 RifRaf when not loaded the motors will use mere milliamps though, but thats rare unless you keep the arm pointed directly up or down, so a good rest position is all servos verticle
04:12 Jak_o_Shadows Yeah, i'm converting an atx powr supply atm
07:50 robotustra morning
08:05 Jak_o_Android Hio
08:23 groglogic anyone with experience making robotics where the controller software used on-board Linux? (not just a direct microcontroller firmware)
08:25 robotustra which controller?
08:25 Jak_o_Android Are you looking at direct control, through something like the GPIO of a RPi
08:30 groglogic don't care about the exact hardware yet, or exactly how to talk to actuators/sensors, just that robotics is happening, and Linux is on that bot. doing research, picking brains for a project idea. (me: i'm a long-time programmer but weak on EE, and utter newb to robotics)
08:30 groglogic Jak_o_Android: Linux/Rpi as the controller would be fine, if you have experience with that I could ask you about. love the Rpi's price point
08:31 Jak_o_Android Nah, no experience, make sure to look at power consumptions
08:32 rue_bed I just built large robots and use a microitx
08:32 rue_bed no messing around with cross compiling
08:32 rue_bed avrs make good io controllers
08:33 groglogic rue_bed: interesting. googling now for microitx and avrs...
08:33 rue_bed avr is the microcontroller used in arduinos
08:34 rue_bed an arduino is just an avr thats good a special bootloader on it, and software made with the arduino libraries via their custom ide
08:35 rue_bed good = got
08:35 groglogic rue_bed: avr, ah thanks. i've some simple arduino programming. microitx: googled that. what kind of model price points have you worked with? i imagine with a larger bot, price and form factor not as much of an issue, so you can get more processing power on-board?
08:36 rue_bed I get them free
08:36 rue_bed everyone is getting rid of the older 500Mhz - 1Ghz ones
08:37 groglogic rue_bed: free? awesome. from employers? or getting them free o ebay/craigslist/like? it seems like you could do a lot with 1GHz, esp if you didn't have a really beefy need like super fancy RT visual recognization processing
08:38 rue_bed just remember that if you can put your software directly on something like an arduino, it'll respond faster than it would thru a pc and back, provided your not doing toooooooooooo much computation
08:38 rue_bed if you know computer peoples they turn up
08:38 rue_bed bbl
08:39 groglogic rue_bed: yeah this project idea I'm research would need to be fully controlled on-board, no phoning home; phone home or tethered might be for optional features; but in normal case it needs to fully functional while un-tethered on the loose
09:02 groglogic on a completely different note, I do sci-fi comedy writing in my free time, in addition to my day job as a programmer, and for my next book I'm introducing a roboticist. would love to pick peoples brains, bounce material off them for feedback. i want this char to be a mix of realistic but funny. looking to others for the realism bit. let me know and I'll msg you a URL/email
11:59 robotustra hate two seasons: mornings and mondays
12:09 robotustra morning, soviet argentina
12:12 GuShH hi robotustra
12:12 GuShH what's your name anyway
12:12 GuShH I won't make fun of it in case it sounds very Russian like Vladimir.
12:12 ShH is just
12:17 theBear probly sergey
12:17 theBear but i bet he knows a vladimir <griN>
12:19 GuShH theBear: he's from Minsk
12:19 GuShH let's see what are the most common names there, in Belarus
12:19 theBear err, umm, igor ?
12:19 GuShH Heh and what's a common Aussie name by the way?
12:19 GuShH I know some Mexican ones, like Carlos and José
12:19 ShH g
12:19 theBear the gays stole all our good names, fred, bruce, julian !
12:19 GuShH Hahaha
12:19 theBear mexican name aussies ?
12:19 robotustra Nickolas
12:19 theBear i like willard better than that !
12:19 theBear chester
12:19 GuShH Damn that's the second nick, dick. I know that is into robotics now
12:19 theBear i dunno
12:19 theBear i been called the bear more than half my life
12:19 theBear names not really my area
12:19 GuShH all my nicks are dicks.
12:19 GuShH o.o
12:20 GuShH I used to know your name!
12:20 GuShH There's a part of my memory that only seems to work when it's soaked in alcohol.
12:20 GuShH Did it start with R?
12:21 GuShH Willard makes batteries
12:21 robotustra GuShH: my name is Nick
12:21 GuShH robotustra: dick
12:21 ShH chuc
12:21 theBear my whois has a hint
12:21 theBear i think
12:22 theBear totally
12:22 GuShH I ... don't do that kind of thing.
12:22 theBear i didn't say you gotta finger anything !
12:22 GuShH Damn I'm lagging today
12:22 theBear it's anonymous and safe !
12:22 GuShH Now I must.
12:22 theBear all the kids are doing it !
12:22 GuShH Oh yeah so it really was Rupert.
12:22 theBear shhhh
12:22 GuShH I thought I was being an asshole by associating it.
12:23 ShH co
12:23 robotustra pipi kaka
12:23 GuShH I just did both.
12:23 theBear nah, its talking about scarves and chequered pants would make you an asshole :)
12:23 GuShH So I'm good for a few hours.
12:23 GuShH Don't worry I was named after a TV actor.
12:23 theBear julie newmar ?
12:23 GuShH o.o
12:24 theBear guillermo ?
12:24 GuShH You're right about Freds being all gay.
12:24 GuShH no that's my brother
12:24 theBear technically homer is right
12:24 GuShH "willy"
12:24 theBear simpson, not the old roman dude
12:26 GuShH Aren't most famous Romans all old?
12:26 GuShH I actually never finished reading the odyssey
12:26 GuShH I have all of them...
12:27 theBear umm, well, popes are progressively less old.... tho they say you should blame the romans for a lot of that whole business
12:27 GuShH So by 2080 we should have a baby pope?
12:27 theBear but i spose that was kinda a change of management by then
12:27 theBear hows that work ?
12:27 theBear oh,
12:27 theBear heh
12:28 ShH wonders if theBear traded his books for audio equipment a long time
12:28 GuShH Books are great, in case of cold weather, set them on fire.
12:28 GuShH Of course these days kids would have to set their ipads on fire
12:29 GuShH which is GREAT.
12:29 GuShH Can you imagine Nazi Germany today?
12:29 GuShH The game Return To Castle Wolfenstein would not be too far fetched.
12:30 ShH thinks the harness was way too tight yeste
12:31 GuShH I gave at least one person nightmares.
12:31 robotustra GuShH: show me your robot
12:31 GuShH Buy me a drink first
12:32 GuShH I said a friend, also named Nick (Nicolas in Spanish) is very much into robotics.
12:32 GuShH It seems all nicks are into robotics.
12:32 GuShH I'm not. I like functional robotics, not fooling-around-with-arduino bullshit.
12:33 GuShH that's like playing with Legos.
12:34 robotustra and?
12:34 GuShH pipi kaka
12:34 GuShH robotustra: can your kids type yet?
12:34 GuShH asdf asdf asdf
12:35 robotustra older can write a bit, but she is already advanced user at youtube
12:35 GuShH haha she's the one bullying me on youtube!!
12:35 GuShH :<
12:36 GuShH robotustra: any signs of robotics interest?
12:36 GuShH or since that's all you probably ever talk about, they're sick of it
12:37 GuShH bah we didn't have youtube back then
12:37 robotustra she has some interest, but not big
12:37 GuShH How exactly is all this technology affecting kids
12:37 GuShH I can only think most of them are affected in a bad way
12:37 robotustra I don't talk about it I just do
12:37 GuShH Aww burns.
12:38 GuShH robotustra: dick
12:38 robotustra I mainly think and write my thoughts about subject
12:38 GuShH On a napkin.
12:38 GuShH Should use a Newton.
12:38 GuShH beat up martin -> eat up martha
12:38 robotustra GuShH: your_CARMA--;
12:39 GuShH carma... carmageddon?
12:39 GuShH I'd substract from your ego, but it already overflowed.
12:40 ShH hifives the
12:41 GuShH robotustra: you actually do talk about it, whether it's before or after you still do.
12:41 GuShH those who don't talk -before- are not sure they're going to finish the project, so they keep it to themselves as to avoid the added pressure
12:42 GuShH https://www.youtube.com/watch?v=8tb3RLqY9Xo
12:43 GuShH Heh MTV... used to be great.
12:43 robotustra may be
12:44 GuShH Ohh look at that kawasaki
12:44 GuShH Yep that's accurate, that's what happens.
13:12 theBear *HIFIVE*
13:12 eBear is good at carmage
13:12 theBear must be about the 20th anniversary of part 1
13:18 GuShH theBear: loved to squish the fat pedestrians
13:19 GuShH and the old ones.
13:19 ShH g
13:20 GuShH getting into the football yard and killing both teams, that was also fun.
13:20 GuShH yard/field
13:23 Tom_itx stadium
13:24 GuShH Tom_itx: alright but technically the car was only allowed to drive onto the field
13:26 GuShH Bah I miss those games.
13:26 GuShH http://images2.wikia.nocookie.net/__cb20100303171359/carmageddon/images/b/bd/Env-C1-BleakBusiness-StadiumEnter.gif
13:27 GuShH If it wasn't for overly concerned parents the other versions of the game would've been much better.
15:41 joga heh carmageddon had a very nice feeling of mass
15:41 joga in the sequels everything seemed to be made out of aluminum
15:47 GuShH joga: some of those newer versions were not made by the same people
15:47 GuShH they didn't even have blood, originally.
15:47 joga wouldn't be surprising
15:47 GuShH (as sold)
15:47 GuShH "zombies"
15:47 joga where I live it was sold with blood
15:47 GuShH green blood
15:47 joga nah, red
15:48 GuShH you had to mod it here.
15:48 GuShH which was illegal
15:48 GuShH heh
15:48 joga I hear in many places they did have the zombie release
15:48 GuShH stupid parents.
15:48 joga never seen it myself though
15:48 GuShH the "2000" one was even worse
15:48 joga heh, yeah
15:49 joga but they were kinda fun still, not as a game but some weird physics sandbox
15:49 GuShH heh
15:49 joga mostly driving big trucks against airplanes or so
15:49 GuShH uhh... terrorist red flag.
15:49 joga ;P
15:50 GuShH hmm it seems every comparator under 100 bucks is "chinese" (well, lower quality)
15:50 GuShH but are they that bad?
15:50 GuShH take digital calipers as an example, they are very good for the cost.
15:51 GuShH a 9 dollar digital caliper will give you the same readout as a 190 dollar one, minus some extra digit, but they are repeatable -- you just can't trust it for absolute precision work, but for most uses they're great.
15:51 GuShH so I'm wondering if a cheapie analog dial indicator is good enough for most uses
15:51 GuShH joga: any idea?
15:52 GuShH I know the fancy ones have ruby mounted gears and whatnot, you'd think that's required for repeatability and precision work, but are these cheap indicators not usable at all?
15:52 joga nah, don't know much about those, my digicaliper is some cheapie that works well, not many other things I've needed :)
15:53 GuShH hell you even get ruby, tungsten, etc. contact stems for the fancy ones, too.
15:53 GuShH but we're talking serious applications vs hobby
15:53 GuShH a 40 dollar chinese indicator has to be at least usable
15:54 GuShH And buying used is a risk
15:54 Tom_itx naw
15:55 Tom_itx all the kinks have been worked out
15:55 GuShH Tom_itx: Bet you've a starrett guy
15:55 GuShH you're
15:55 Tom_itx my digital is B&S
15:55 Tom_itx iirc
15:55 Tom_itx err no, fowler
15:55 Tom_itx the dial was B&S
15:56 GuShH I can get pretty good ones in used state, I just don't trust them to be in fully functional form
15:56 GuShH to indicate on a 4 jaw chuck and other simple operations the chinese one has to be good enough for now, surely
15:56 GuShH I wonder if extra care must be taken on these
15:57 Tom_itx my last word is a Mitutoyo
15:57 GuShH Now they're made in Brazil
15:57 Tom_itx japan
15:57 GuShH No, brazil.
15:57 Tom_itx these were
15:57 GuShH they have a factory there
15:57 GuShH Well, yes. originally
15:57 Tom_itx it says so
15:57 GuShH But even japanese motorcycles are made in India and China these days
15:57 GuShH except for the highest end ones
15:58 GuShH like an R1
15:58 GuShH (and I'm willing to bet they actually use imported bits and pieces)
15:58 GuShH It's all about cost, quality can be the same or better if you pay for it.
15:59 GuShH Tom_itx: so in essence these indicators could be the same thing, but with lesser quality materials, less QC, etc. right?
15:59 GuShH and possibly poop mounted gears instead of ruby.
15:59 GuShH http://www.mitutoyo.com.br/site/index.html
16:00 GuShH So, new units sold here are made in Brasil. Only Japanese units to be found are used :(
16:04 Tom_itx so buying used may be better than buying new :)
16:05 GuShH Ah, but how do you make sure you aren't getting a dud?
16:05 Tom_itx with new?
16:05 Tom_itx you can't
16:05 GuShH used.
16:05 Tom_itx :)
16:05 GuShH Also I rushed and bought a magnetic base from eBay because it was half the price, but now I've got to wait almost a month to get it
16:05 Tom_itx i know what you meant...
16:05 Tom_itx i got a crapper magnetic base
16:05 GuShH With new I reckon, if I bought it locally, I could shove it up their eye socket.
16:06 Tom_itx i don't use it that much anyway
16:06 GuShH I need some sort of base to check runout on the chuck, etc
16:06 Tom_itx you could mount it to the tool post
16:07 GuShH yeah but what about centering parts and not wasting too much time fooling around with the toolpost? even though I could come up with a quick way to mount it
16:07 GuShH Remember I don't have a quick change toolpost
16:07 GuShH For some reason they cost almost half of what the lathe costs
16:08 GuShH Or maybe I've been looking at the wrong end of the spectrum
16:10 GuShH Not sure why they went with red http://www.ebay.com/itm/370745928529?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
16:10 GuShH seems the magnetic force is weak compared to the expensive ones, among other things heh.
17:16 GuShH Tom_itx: oh wow... it really gets deep http://www.mmsonline.com/columns/gage-contacts-get-the-point
17:17 GuShH So for aluminum a tungsten tip is not a good idea, who knew
18:08 robotustra GuShH: that's why cnc mill gives me only 50 microns
18:08 GuShH robotustra: sorry?
18:09 robotustra your article
18:09 robotustra it's not rigid
18:09 GuShH well, not mine. but what about it?
18:09 GuShH yeah, that's why alu is not used
18:10 GuShH and where it's used, it's not for precision
18:10 GuShH robotustra: But for your application, why would you want anything better?
18:11 GuShH Also, are you sure it's not higher than 50u
18:11 robotustra I don't need it right now
18:11 robotustra theoretically 1 step of motor it's 4 micrometer
18:12 robotustra I have 6000 steps per 1"
18:12 robotustra but rigidity and all other spaces
18:13 robotustra I think 20 microns I can do, but for small parts
18:13 robotustra and soft materials
18:13 GuShH have you identified the culprit or is it the sum of all parts that causes it
18:13 robotustra I cut the hole in a vise accidently
18:13 GuShH and did you indicate the spindle, by the way :p
18:13 robotustra and it mean that I can mill iron also
18:14 GuShH well, given a low enough rate you can mill most materials if your tool can handle it
18:14 GuShH I like how iron powders instead of chipping
18:15 GuShH Had to oversize some holes on a cast iron housing not long ago, very easy to work with
18:16 robotustra I didn't measure deformation somehow
18:17 robotustra I just measure final part
18:17 robotustra and see the devation from what I put into g-code
18:17 robotustra for instance, robot eye has 60 mm size
18:18 robotustra I measured the actual diameter is 59.98 mm
18:18 GuShH getting closer wrt tooling, tailstock chuck and the indicator for the lathe... let's see if I can get it within this week, finally. Stupid stores taking ages to send me the pricing and answering in return
18:18 GuShH robotustra: but you have to see what's causing it, is it the tool?
18:19 robotustra or when I mill 6 mm hole for bearing it fits very tight when I mill 5.98 mm diameter
18:19 GuShH is the spindle off centre
18:19 GuShH is your material not being held properly
18:19 GuShH or are you sure it's just the flexing of all parts that sums it up
18:19 robotustra it's holding good, I cnow how to work with vise
18:20 ShH didn't say
18:20 GuShH your registration is correct? zeroing
18:20 GuShH and if you are sure it's not the spindle nor the tool...
18:20 robotustra f u c k o f f
18:20 GuShH huh
18:20 GuShH You said you never measured it on the machine, but the finished parts
18:20 robotustra I'm physisict
18:20 GuShH you're a joke if you are not measuring your machine
18:20 robotustra I know the theory of errors
18:21 GuShH You can't even type what you "are"
18:21 robotustra and you probably not
18:21 GuShH Which tells me you were taught in a drain pipe by a drugged up rat.
18:21 GuShH This is not theory, boy. This is the real world.
18:23 robotustra do you know this theorem http://en.wikipedia.org/wiki/Weierstrass_approximation_theorem
18:23 GuShH Now he's wiking me.
18:23 GuShH Did you get your degree thanks to Google?
18:23 robotustra my real world shows me 20 micrometers
18:24 GuShH robotustra: you need to learn modesty if you want others to be modest. Likewise don't assume others are being condescending when they might have genuine interest in helping you. Oh if you really think you don't need help, you are full of shit and will probably drown on it.
18:24 GuShH Also, why would I even want to show you my feathers
18:24 GuShH This is IRC nobody has to prove you anything.
18:24 robotustra when I learned this theorem in the university Google did not exist yet
18:24 robotustra so, relax
18:24 GuShH Yeah you were probably reading by candle light.
18:25 robotustra you are lucky that I can't kick your ass
18:25 GuShH Ha
18:25 GuShH Keep assuming and you'll end up like your average roadkill.
18:25 robotustra anyway, I know that's all lashes are about 20 microns
18:26 robotustra if the feed is big - i get bigger deflection from sizes
18:26 GuShH You should've known when you chose your materials, so quit complaining.
18:26 robotustra and this is a construstion
18:27 GuShH I don't know what that word is.
18:27 GuShH But this occurs with any material, better said, with all materials.
18:27 GuShH Nothing is fixed nor constant
18:27 GuShH Everything is moving and changing.
18:27 robotustra construction
18:27 GuShH Accept it and quit complaining.
18:28 robotustra I accepted it, I just told you what I have
18:28 robotustra and that's it
18:28 robotustra it's still much better than any 3D printer
18:28 GuShH Not too long ago you couldn't fathom 50 microns on a homemade CNC mill.
18:28 GuShH Because tooling and parts in general were a lot more expensive.
18:29 robotustra may be
18:29 GuShH The spindles alone.
18:29 robotustra this spindle is quite good
18:30 GuShH I bet 20-30 years ago nobody in China was making those, or rather, copying them.
18:30 robotustra I cut the slot with 1/8 mill - measire it - it's 3.18 mm
18:30 GuShH Maybe even 10 years.
18:30 robotustra less
18:30 GuShH I don't know the exact number, I know it wasn't available that long ago.
18:31 GuShH You had prices like 800 bucks and up
18:31 GuShH So that's a good thing
18:33 GuShH robotustra: Do you know if the color "marine grey" has some other name?
18:33 robotustra I think original price was about 1000
18:33 GuShH I could match it with pantone but...
18:33 GuShH (and get a custom mix)
18:33 robotustra no I don't knoe names of colors
18:33 GuShH me neither, evidently.
18:33 robotustra know
18:34 robotustra I know that colors have indexee
18:34 robotustra and you can get it by index
18:34 GuShH my pantone chart has expired
18:34 GuShH LONG AGO
18:35 GuShH ok if this website is correct, then marine grey is not what I'm looking for.
18:35 GuShH http://www.benjaminmoore.com/en-us/paint-color/marinagray
18:36 GuShH it's a mix between this and that http://www.benjaminmoore.com/en-us/paint-color/rockcandy
18:36 ShH thinks he will need to go with the part to a big paint store and get it color matched, end of s
18:36 GuShH I wonder if their color match software tells them what the specific colour looks "more like" (ie. name)
18:37 robotustra yep
18:37 robotustra in canada stores they do any color you need
18:37 GuShH Your colour looks like: gay-ass marine
18:37 robotustra and any volume
18:37 GuShH yeah same here, but I thought it was a standard one
18:38 GuShH robotustra: you can also get it in spray can, color matched.
18:38 GuShH more expensive though.
18:38 GuShH we got a set for my brother's jetta, comes with primer, colour and clear coat... but it wasn't exactly the same, I think they had trouble matching the metallic colour
18:39 GuShH in theory it's averaged out throughout a specific sampled area under the correct lighting / exposure
18:39 GuShH and of course it's a calibrated process
18:39 GuShH who knows, maybe their solvent batch was slightly off, etc.
18:39 robotustra I painted my violins with a paintbrush and it worked well
18:40 GuShH polyurethane, diluted?
18:40 GuShH tends to self-level very well
18:40 robotustra no, spiritus based varnish
18:40 robotustra or oilish
18:40 robotustra oil is the best
18:40 GuShH bleh, if correctly diluted it levels just as well.
18:41 robotustra spiritus - you have to know triks how to make it even
18:41 GuShH robotustra: of course you always block sand and polish anyway if you want a perfect result
18:41 robotustra yes
18:41 robotustra polishing is a must
18:41 GuShH with spray, you get all sorts of issues.
18:42 robotustra first and principal one is thickness
18:42 robotustra and uneven covering
18:42 GuShH that's the trick with spray painting, how much to thin your paint.
18:42 GuShH coverage is all down to technique
18:42 GuShH I suck at that when it comes to big parts.
18:43 GuShH the fan is set correctly, the overlap is just about 50% but I never get it perfectly right.
18:43 robotustra for violins it does not work
18:43 robotustra I spend like 50 grams of varnish per violin
18:43 GuShH (distance is another factor)
18:43 GuShH (feed rate too)
18:43 GuShH are you a luthier?
18:44 robotustra to varnish violin fis air gun you need at least 500 g
18:44 robotustra something like this yes
18:44 robotustra I did 14 violins
18:44 GuShH on HVLP you ought to need much less.
18:44 robotustra and repaired a lot
18:44 GuShH but everything I have is HPLV
18:44 robotustra hundreds in 10 years
18:44 GuShH so you tend to waste paint.
18:45 robotustra bows also
18:45 robotustra rehairing and repair
18:45 robotustra one day I'll continue on a new level
18:45 GuShH oh?
18:46 GuShH CNC violins is not the way to go
18:46 robotustra roughing cuts is ok
18:46 robotustra fine turning by hands
18:46 GuShH pff, cheater.
18:47 robotustra who told me that?
18:47 GuShH I just did?
18:47 robotustra yep another cheater
18:47 GuShH You are from the group "If our ancestors had the tools they would've used them!"
18:47 GuShH chances are that's correct.
18:48 GuShH it's technology and you apply it.
18:49 robotustra technology it's one side
18:49 robotustra but you have to know how to apply this technology
18:50 robotustra there is a "secrets"
18:50 robotustra there are
18:50 robotustra but it's more knowledge than "secrets"
18:51 Tom_itx common sense
18:51 robotustra if you don't know this knowledge - no technology helps you
18:53 robotustra I learned a lot of stuff about violins, now can say I'm illuminated
18:54 GuShH he got violated
18:55 robotustra And btw I'm the latest violin maker from Belarus with Cremona school traditions
18:56 robotustra Fiorini -> Yarovoy -> Chaikov -> Stasevich -> me
18:57 GuShH I'm the pope's hat
18:58 robotustra nice to meet you, pope's hat
19:00 GuShH robotustra: isn't it time for your pills?
19:02 robotustra no, it's time to see something on youtube
19:02 robotustra It's time to feed my friend's cat
19:02 robotustra thank you
19:05 GuShH robotustra: admit it's your cat
19:06 ShH believes robotustra was involved in directing the creation of the milkyway by telling the dust where it should go as
19:06 GuShH he also gave birth to god.
19:07 robotustra take higher
19:07 GuShH no, take your pills.
19:10 robotustra feed cat first
19:17 GuShH robotustra: in soviet russia cat feeds you
19:34 Tom_itx that _is_ rather an art
19:34 Tom_itx or craft
19:35 Tom_itx not your average HS punk can craft a quality violin
19:48 GuShH who needs a violin when there's an app for that?
19:50 robotustra it's art and craft
19:50 robotustra from the beginning is a craft for sure
19:51 robotustra after when you know more - the art begins
20:03 GuShH robotustra: I bet asimo plays it better than you!
20:23 robotustra asimo doesn't play violin
20:24 robotustra I play not much
20:24 robotustra I didn't learn how to play violin, I play balalajka
20:24 robotustra if you know what is this
20:25 robotustra http://www.youtube.com/watch?v=5JqeSU7lSLE
20:48 GuShH robotustra: it plays
20:48 GuShH playback of playing.
21:07 MrCurious jesus spark fun. why did you go with a non standard 3.5 spacing on these pins
21:07 MrCurious is it because you want to be the sole damn source for the terminals?
21:10 MrCurious not easily possible to be MORE annoyed right now
21:10 GuShH MrCurious: what else did you blow up now?
21:11 MrCurious https://www.sparkfun.com/products/10507
21:11 MrCurious needs 3.5mm pitch terminals
21:12 GuShH that's a ripoff
21:12 MrCurious if you are going to requore non standard terminals, package them with the god damned product
21:13 MrCurious time to start chanting woo-sah
21:13 GuShH for 65 dollars it should come covered in cocaine
21:14 MrCurious $0.95 PER terminal block
21:15 GuShH on that same site? you never learn
21:15 MrCurious because sometimes people only want ONE and they want to pay shipping on top!
21:15 MrCurious might as well live in argentina!
21:16 GuShH MrCurious: sparkfun is like a small argentina in your country
21:16 GuShH enjoy
21:19 MrCurious spark fun, i rename thee to spark fucked
21:21 GuShH spankfun
21:21 GuShH MrCurious: oh well, don't I complain for a reason?
21:21 GuShH I've once ranted about them, should've heard!
21:21 GuShH lol 2 bucks for this? https://www.sparkfun.com/products/11510

21:26 GuShH 20c a pop
21:26 MrCurious thanks, already ooked at ebay
21:26 MrCurious was hoping for somewhere that would arrive this month
21:26 GuShH oh well, bend over and take it from sparkfun again then
21:27 GuShH "I want it nao" fags.
21:27 GuShH it's best if you've got multiple projects going on at once
21:27 GuShH MrCurious: plan ahead, order everything you need, move to the next project, go back once you've got the parts, etc.
21:27 MrCurious i have lots of projects going
21:28 GuShH then bad timing is your problem.
21:28 MrCurious but this is the one that has the spinny wheels that makes teh stepper noise that i am infatuated with this week
21:28 MrCurious some days are like this
21:28 GuShH aren't you in a proper country
21:29 GuShH can't you just walk to a big ass store, browse and grab whatever you want
21:29 GuShH even I can get these things at the store
21:29 MrCurious actually.. let me check teh big assed store's site... frys.com
21:29 GuShH but I end up paying as much as you do on sparkfun if I buy locally
21:30 GuShH they have electrical ones...
21:30 GuShH what a bunch of shit http://www.frys.com/product/7087841?site=sr:SEARCH:MAIN_RSLT_PG
21:32 MrCurious thinking i need to suck it up and spend (8) * $0.95 + $8 shipping from spark fun
21:32 GuShH http://www.frys.com/product/7288723?site=sr:SEARCH:MAIN_RSLT_PG this was suggested when looking for screw terminals
21:32 GuShH terminal -> terminator
21:32 GuShH MrCurious: you could get 100 from chinkland
21:34 GuShH quit feeding the skunkfun weasels.
21:35 GuShH if they could they would charge you for the air trapped inside their gay ass red cardboard boxes.
21:36 MrCurious its my fault. i should have read every word on the page
21:37 MrCurious then i would have known the spacing was off, and only special spark fun terminals will work
21:38 MrCurious 3.69 shipping
21:40 Curious hangs his head in sucker s
21:42 MrCurious 10 - $8.60 - PRT-08084 - Screw Terminals 3.5mm Pitch (2-Pin) ($0.86 ea.) + $3.69 shipping
21:42 MrCurious only needed 8, but if you go to 10, its like getting 1 free for the price of 9!
21:42 GuShH what a puppet
21:46 GuShH MrCurious: I bet you'll be missing something else, since they always sell you incomplete stuff on purpose
22:00 MrCurious *SIGH*
22:03 GuShH MrCurious: :|
22:15 robotustra sperminator
22:15 GuShH robotustra: you should get one of those
22:16 robotustra or build
22:16 GuShH no comment
22:16 robotustra played some Urban Terror
22:17 robotustra killed some enemies
22:20 GuShH but you didn't win
22:23 robotustra today 2-3
22:24 robotustra first couple of times but in the team of loosers
22:25 GuShH robotustra: do you think the others cheated?
22:25 robotustra no
22:25 GuShH what if they did
22:26 robotustra admin kick cheaters
22:26 GuShH admins are clueless
22:26 robotustra if you provide spec
22:26 robotustra but it's usually evident
22:26 ShH goes to
22:26 robotustra to early
22:27 GuShH 12:12
22:27 GuShH some people cheat but they play dumb
22:27 robotustra you must to do the frame
22:27 GuShH got other things to do first.
22:27 robotustra if smbdy hit the head more than 15% - it's cheater
22:28 GuShH in counter strike source I often had 80% headshot rates
22:28 robotustra have some sex before?
22:28 robotustra if you are sniper
22:28 GuShH lots of deaths
22:28 GuShH you can do a lot of heatshots but die a lot as well
22:28 GuShH if you take your time to aim, you might get shot first
22:29 robotustra I usually do 11%
22:29 robotustra yes
22:29 GuShH not a sniper, with the MP5
22:29 robotustra that's why 11% is reasonable value
22:29 GuShH people still play the old CS
22:30 GuShH I don't know why
22:30 robotustra I like UT more than CS
22:30 GuShH Got tired of UT
22:30 robotustra more quake like
22:30 GuShH I could still play quake3
22:30 robotustra me too, but there is no alternative
22:30 GuShH not the 4, it was crap
22:31 robotustra I'm too old to play many games
22:31 GuShH you are too old, period.
22:32 robotustra one game - I'm younger than MrCurious
22:32 robotustra and don't drink bear
22:32 robotustra beer
22:32 GuShH yeah when MrCurious goes to take a piss, dust comes out.
22:33 robotustra make sure he is looking for terminals
22:33 robotustra and not here
22:34 GuShH I don't know, I would've ordered them from China and soldered something else in the meantime.
22:34 GuShH It's not like you can't desolder parts.
22:34 GuShH I bet they're the same terminals
22:36 robotustra there are 2 types of them
22:36 robotustra 5 and 3 mm
22:36 robotustra I had small one on DC Monor driver PCB
22:37 GuShH http://www.benjaminmoore.com/en-us/for-your-home/rooms-by-color/storybook-neutral-bedroom
22:37 GuShH lol, the comment. nobody even moderates them
22:37 robotustra but still I don't beleive in connection other than soldering
22:38 GuShH I use screw terminals for electrical work
22:38 GuShH it's nice.
22:38 GuShH But the big strip ones
22:39 MrCurious smells dusty in here
22:39 GuShH http://grsmicroliting.com/images/CK1049.gif and http://i01.i.aliimg.com/photo/v0/521740167/Brass_Electrical_Screw_Wire_Terminal_Blocks.jpg
22:39 GuShH as long as your wires are twisted and soldered, you get a pretty reliable connection, it's a lot better if you keep them enclosed too...
22:40 GuShH however most electricians wont' solder a shit.
22:40 GuShH most electricians in fact are monkeys.
22:55 MrCurious i am so lost i am at the wrong terminal and my flight of fancy takes off any moment!
22:57 MrCurious suppose i could have gotten tiny O loopes and tiny nutt/bolys and washers
22:57 MrCurious and beat them that way
23:08 robotustra connectors is the main issue for compact robots
23:09 robotustra for instance for small PCBs like odroid ,RPi, the place whish standard connectors take is huge in my opinion
23:10 robotustra look at this ugly stuff http://com.odroid.com/sigong/_Files/2012/201211/images/201211242034331171.jpg
23:10 robotustra sleep
