#qi-hardware IRC log for Friday, 2014-05-23

DocScrutinizer05indeed I also wonder what they did to make those chip antennas. Watching the roundabout 2412 antenna of R0ket00:00
DocScrutinizer054.5mm length00:01
DocScrutinizer051,? mm wide00:01
DocScrutinizer05http://www.r0ket.de/ the white thingie on top00:02
DocScrutinizer05http://www.johansontechnology.com/images/stories/ip/rf-antennas/Antenna_2450AT42A100_08-29-2008.pdf00:03
wpwrakquite small indeed00:04
DocScrutinizer05average "gain" -1dBm00:06
DocScrutinizer05which isn't bad at all for such a tiny critter00:06
DocScrutinizer05r0ket is completely awesome00:30
DocScrutinizer05and they use one LED dual-use as ALS  :-D00:33
DocScrutinizer05"attention! when you enable the red charging LED, you can't detect ambient light level anymore"00:34
wpwrakno time-sharing ?00:35
Action: DocScrutinizer05 idly wonders if, when you pulse a LED with 2MHz, you could tell apart a white from a black paper covering the LED00:35
DocScrutinizer05during the off periods00:35
DocScrutinizer05with no ambient light00:35
wpwrakkinda difficult to set up00:37
wpwrakbut try it :)00:37
DocScrutinizer05anyway that's awesome design, almost like the stuff I take pride in designing. Just a LED and a series R connected to a multifunction MCU IO00:38
DocScrutinizer052 components for two functions00:38
DocScrutinizer05plain brilliant00:38
wpwrakyou challenge for today is to also make it detect and emit sound. tomorrow, make it emit RF in the 900 MHz band ;-)00:39
DocScrutinizer05hehe00:39
DocScrutinizer05emit sound I guess I already achieved years ago. Alas the livespan been *very* short00:40
Action: whitequark giggles07:53
wpwrakDocScrutinizer05: modified challenge: emit native american smoke signs ... in various dialects :)08:07
wpwrakxkcd is pleasantly evil today ;-)08:15
whitequarkwpwrak: btw, I did a few more experiments with acrylic last night12:05
whitequarkI am now certain about two things:12:05
whitequark1) feedrate really only affects the finish, as long as it doesn't break your endmill. I set it to various values from 100mm/min to 1200mm/min, without too much difference12:06
whitequark2) getting a lot of coolant is *really* important. without coolant, no matter how slowly or quickly you go, the results are shit12:06
whitequarkwith coolant, it's the exact opposite12:06
whitequarkwithout enough*12:07
whitequarkand "enough", as I now see, means "you need a bucket under your table"12:07
whitequarkabout 1L per 5min12:07
whitequarkso if you're fine with a matte, slightly rough surface, go 800mm/min. if you really need it to be transparent like glass, go for 10012:10
whitequarkbut in the latter case, prepare to haul water for forty minutes (I need to make it closed-loop or something.)12:10
wpwrakhmm, odd. my acrylic doesn't act like yours. no overheating issues at all, but the finish is always rough, especially on areas where the mill worked from Z+12:16
wpwrak(water) how about getting a metal sheet to which you attach acrylic et al., then make a "dam" around it with silicone. then you can just flood the workpiece.12:17
whitequarkthat sounds too ad-hoc for me12:19
whitequarkI like my idea much better, it's pretty simple12:19
whitequarkthe Al table, to which my wooden clamp attachment thing is mounted, already has slots, and the machine itself is slightly tilted to front12:20
whitequarkI could just mount a water collecting thing in front of it, where the bulk of water will go, and drain it somewhere12:20
whitequarkpro: no fiddling with silicone needed, no large quantities of water somehow stored in the machine and then drained via inexplicable ways12:21
whitequarkcon: slightly more complex12:21
whitequarkwpwrak: it may be relevant that I use an endmill with diamond pattern12:22
whitequarkas I understand, it's basically for fiberglass, and it heavily rubs the material, hence all the heating12:22
whitequarkin principle one should use a 1-flute endmill for that, but I've had limited success obtaining endmills with the properties I want so far12:23
whitequarkwpwrak: (finish) with the "FUCKING DROWN IT ALL"" technique I can get a finish where the (milled) side is almost indistinguishable from the (cast) surface12:24
whitequarkit's not *entirely* smoothly transparent, but it's pretty close12:24
whitequarkI think I can get it to be completely transparent by going even slower and with better fixture to avoid miniscule shifts of workpiece between layers12:25
whitequark(if I try to mill the entire depth of workpiece, it appears that the supply of coolant is inadequate, as it cannot get to the very bottom of the hole)12:25
wpwrak(smooth finish) maybe i should try a diamond pattern too :)12:31
wpwrakalways used 2-flute so far12:31
whitequarkmaybe you should try using coolant?12:36
whitequark(2-flute) how fast/slow does your machine go?12:36
Action: DocScrutinizer05 just wondered how much (in kg of gold) a mill bit with embedded channels for feeding coolant directly to the blades would be12:36
whitequarkwpwrak: the idea with 1-flute endmills is that they're good for crappy desktop router machines, which have sync motors which are only efficient when going really fast12:37
DocScrutinizer05but maybe when I register a patent, I even could afford one or two of those critters from what the patent earns me X-P12:37
whitequarkso you have twice lower MRR with same rpm and same hp12:37
whitequarkif your machine has an async motor which can go slow, using 2-flute endmill is just as fine12:38
whitequarkDocScrutinizer05: there are actually tool chucks with embedded coolant channels12:38
whitequarkI don't think there are actual endmills, but who knows12:38
DocScrutinizer05thought as much. CRAP12:38
DocScrutinizer05another wasted patent12:38
DocScrutinizer05I guess with a laser tool you even could build endmills with such channels "drilled" into them12:40
whitequarkDocScrutinizer05: "coolant-through cutting tools" is the right google query12:41
DocScrutinizer05o.O12:41
whitequarkWHOA12:41
whitequarkhttp://www.guhring.com/ProductsServices/Tools/?Type=EMCF12:41
whitequarkthis is literally what you are talking about12:41
DocScrutinizer05YAY, EXACTLY!12:41
DocScrutinizer05knew it, again too late for patenting ;-P12:42
whitequarkI wonder how expensive it is12:43
whitequark$74: http://www.ebay.com/itm/Guhring-7-8-Solid-Carbide-8-1-2-Long-Drill-Through-Coolant-875-guehring-/12134742884212:43
whitequarkusually around $5012:44
DocScrutinizer05sure, but they start at 6mm. Thought as much12:45
DocScrutinizer05getting a 1.5mm will be impossible12:45
whitequarkprolly possible, but it will seriously degrade structural quality12:45
whitequarkhm, how do you make endmills?12:46
whitequarkcasting?12:46
DocScrutinizer05hardly, but you need purified water to not clog the laser holes12:46
DocScrutinizer05(hardly decrease struct integr)12:46
whitequarkwell, then just run it in an open-loop system?12:46
DocScrutinizer05sure12:46
whitequarkbring fresh (even tap) water in, collect wet chips outside12:46
DocScrutinizer05which btw is anyway the cheapest12:47
whitequarksay just in a huge tank and wait for it to evaporta12:47
whitequarkevaporate*12:47
DocScrutinizer05or just filter12:47
DocScrutinizer05Melitta coffee filter will do a great job for that12:47
whitequarkor do like NPO Mayak does it with radioactive waste and just dump it to the nearest lake12:47
DocScrutinizer05lol12:47
whitequarkyou heard that story?12:48
DocScrutinizer05nope12:48
whitequarkooooh you will LOVE it12:48
DocScrutinizer05prolly not12:48
whitequarkNPO Mayak is russia's nuclear waste processing / warhead plutonium extracting facility, built really long ago by soviets12:48
DocScrutinizer05just the usual idiocy and moral corruptness12:48
whitequarkthey were once going to collect the highly active waste in reservoirs, but it turned out that it's too radioactive for that12:49
DocScrutinizer05we see almost exactly same in Italy all over12:49
DocScrutinizer05with toxic waste12:49
whitequarkso they literally dump it into three lakes around the facility. near the outlet, 1hr spent in a lake is immediately lethal12:49
whitequarkit's *that* active12:49
whitequarkactually my estimates based on current data is that after 20 min, you aren't even going to get out of the lake12:49
whitequarkthey also have accidents fairly regularly12:50
DocScrutinizer05great location for holiday and fetch souvenirs12:50
whitequarkonce there was an accident, in which the *head of nuclear safery* grossly neglected the aforementioned safety, went into a hugely contaminated area and promptly died there12:50
whitequarkjust think about it for a minute12:50
DocScrutinizer05LOL12:50
DocScrutinizer05rotfl12:50
whitequarkthey were transferring 70L of very active Pu-containing liquid, the worker who was doing it accidentally caused criticality, was scared by flash and cracked the container12:51
whitequarkwhich for some inexplicable reason was made of fucking glass12:51
DocScrutinizer05maybe they should fill it into vodka bottles12:51
whitequarkso now they have a huge plutonium puddle12:51
DocScrutinizer05ooh criticality incidents, one of my fav wiki pages12:52
whitequarkhead of nuclear safety goes in and does some shit (don't remember exactly) with the puddle and the rest of container, causes *another* criticality accident and gets enough dose to die in a day or so12:52
whitequarklike how fucking dumb exactly do you need to be12:52
DocScrutinizer05to work in such facility? dunno, inevaluable12:53
whitequarkthey also irradiated several million people downwind across the five decades the facility is operating, to significant levels12:53
whitequarkit was all denied until quite recently12:53
whitequarkno one was even told they were at risk, much less given preventative measures12:54
DocScrutinizer05http://en.wikipedia.org/wiki/Criticality_accident12:54
whitequarkand on the river that gets quite some of the water from said lakes, there are still three villages12:54
whitequarkhttp://en.wikipedia.org/wiki/Mayak12:54
whitequarkthe whole facility looks like something out of a cliché video game12:55
whitequarkand operates12:55
DocScrutinizer05Russian justice: we are poisoning our own people, so why the heck should we worry about poisoning the globe12:55
wpwrak(head of safety) well, you could call his actions heroic :) remember K-19 ...12:56
DocScrutinizer05K-19?12:56
whitequarkit seems to be a common theme in soviet interpretation of nuclear safety12:56
wpwrak(irradiated people) that's how homo sapiens radians was created :)12:57
whitequarksee also: Semipalatinsk nuclear range, with several hundred underground detonations, again without any info or protection to the residents whatsoever12:57
DocScrutinizer05yep, awesome12:57
whitequarkor the infamous military training12:57
DocScrutinizer05most of those detonations been for hydrogen gas though, iirc12:57
whitequarkwhen the soviets dropped a bomb on their own territory and within a hour marched an army over that12:57
DocScrutinizer05US did same12:57
DocScrutinizer05"we need to test that case"12:58
whitequarkafaik, the US at least pretended to take some precautions, or just told the soldiers what exactly they were dealing for12:58
whitequarksoviets did neither12:58
whitequarkno fucks about safety given whatsoever--except for the officers, of course12:58
DocScrutinizer05usual12:58
wpwrak(k-19) a russian nuclear sub that had a reactor problem while at sea. people went in with chemical protection suits to fix it. eventually they succeeded, but ...12:59
DocScrutinizer05a soldier is cheaper than a full body protective siut12:59
wpwrakthere's a movie on it,. K-19: The Windowmaker. quite worth watching.12:59
DocScrutinizer05yeah12:59
DocScrutinizer05know it12:59
whitequarkDocScrutinizer05: semipalatinsk has seen about 498 nuclear and themonuclear explosions12:59
wpwrakwell, they were supposed to have such suits on board. but then, i guess russian logostics aren't up to, say, german standards ...13:00
DocScrutinizer05oops, I mixed that with your toxic waste site13:00
wpwrakwhitequark: well, once upon a time, the us sent soldiers into bomb fallout, too. you russians are just a little late in stopping the atrocities ;)13:01
whitequarkwpwrak: it has happened at about the same period13:02
whitequarkthe fallout exercise: http://en.wikipedia.org/wiki/Totskoye_nuclear_exercise13:02
whitequark"Even the soldiers who participated in the exercise did not know that they had taken part.[3] The government congratulated the local population for their heroism in providing the nuclear shield for their Motherland."13:04
whitequarkcompare to Desert Rock: "Their purpose was to train troops and gain knowledge of military maneuvers and operations on the nuclear battlefield. They included observer programs, tactical maneuvers, and damage effects tests."13:06
whitequarkwhat the US did was quite evil, but it was at least remotely sane. also, up to 20k participants13:06
whitequarkthe soviet approach is just plain deranged13:06
whitequark45k people!13:06
DocScrutinizer051944 Los Alamos (first criticality eccident) is still my fav one13:07
DocScrutinizer05accident*13:07
DocScrutinizer05first *fatal* accident, that is13:08
DocScrutinizer05 Louis Slotin13:09
DocScrutinizer05and before him,  Harry K. Daghlian13:10
DocScrutinizer05but  Harry K. Daghlian took 25 years to die from the accident13:10
DocScrutinizer05err days13:10
Action: DocScrutinizer05 wonders when coffee will start to kick in13:11
DocScrutinizer0530 December 1958  Cecil Kelley, also brilliant epic failure, though the operator probably was innocent victim13:13
DocScrutinizer05the error pattern itself however is awesome13:13
DocScrutinizer05you can watch it in your teacup every day, when you use sugar in your tea13:14
DocScrutinizer05Wood River Junction  --  epic13:15
wpwrakwell, 20k vs. 45k doesn't sound like such a huge difference ...13:16
DocScrutinizer05LOL! >>The shift supervisor then deceived the radiation control supervisor and entered the room of the incident and possibly attempted to pour the solution down a floor drain, causing a large nuclear reaction that irradiated the shift supervisor with a fatal dose of radiation.<<13:17
DocScrutinizer05I can't help but I love russian mentality13:18
whitequarkyep yep, that's the accident I was talking about13:19
whitequarklet me get more details13:19
whitequarkI've seen an official report somewhere which really elaborated on the incredible stupidity that caused it, but I can't find it again13:23
whitequarkalso, it's in Russian anyway13:23
whitequarktake a look at this: http://www.yabloko.ru/Publ/Atom/atom00018.html13:23
whitequarkIntermediate-and low-level LRW continue to dump into Lake Karachay, and it remains a potential source of large-scale radiation accident in the case of ash contaminated water under the influence of possible tornadoes. Formed near Lake Karachai lens contaminated groundwater continues to move to the river Mishelyak. Its boundary to the nitrate ion in a southerly direction reached Valley Mishelyak. "Mayak" is largely limited to passive monitorin13:24
DocScrutinizer05I never know if it's soviet every day situation or a painting of H.R. giger13:24
whitequarkeven funnier: NPO Mayak doesn't have the license for operation of hydraulic structures by our own federal law13:25
DocScrutinizer05I could bet on that13:25
DocScrutinizer05hydraulic structures are not supposed to be used for any type of radioctive material processing13:26
DocScrutinizer05it would be like me having a permission to handle Pu because I build electronic devices13:27
whitequarkwell, I mean, they could in principle get a license for building an artifical lake, without specifying any concrete purpose13:28
whitequarkbut welp, why bother13:28
whitequarkyou can just dig a hole and fill it with boiling plutonium waste13:28
kyakjust don't make conclusions about "russian mentality", as you called it, based on your quite frankly limited knowledge about Russia13:31
whitequarka cavalier approach to danger *is* something you can clearly observe in practically any industry13:32
kyakwpwrak: congrats with participation in Neo900 project! This should've happened long ago :)13:37
ysionneauah wpwrak contributed to Neo900?13:48
kyakaccording to the latest announcement, Werner is now the crew member14:00
wpwrak"a" member ;)14:26
wpwrak"the crew member" would be indicative of a bit of a problem14:27
kyakit was "a" at first, but then i thought that the article belongs to "crew" and therefore woudl indicate "some" crew :)14:34
wpwrakit was a good theory, but unfortunately incorrect ;-)14:37
kyakyeah, i was just finding excuses :)14:38
kyakit suddenly occured to me that there are no native English speakers here14:42
kyaki don't know what's "here" but anyway14:42
wpwrakat the moment, this may indeed be true14:43
Action: wpwrak notices that, after 3rd or 4th time, making a new variant of some layout (from scratch, else it wouldn't be fun), gets remarkably easy14:45
ysionneauwhat are you going to do for Neo?14:47
ysionneauwhat's your mission ? :)14:47
wpwrakat the moment, mainly moral support :) then checking things, schematics and such. later on, possibly take care of QA (production testing procedures)15:07
ysionneaucool!15:17
ysionneauplease integrate anelok in the neo900 design :p15:18
ysionneauso that the phone can do password safe as well15:18
wpwrak;-))15:21
wpwraki wonder it i should try to sneak in idbg :)15:22
DocScrutinizer05too late16:41
DocScrutinizer05Nik been faster than you16:41
DocScrutinizer05kyak: what else do you suggest I should base my conclusions on?16:43
DocScrutinizer05wpwrak: are you registered to ML meanwhile?16:43
DocScrutinizer05(idbg) still the probably better design, go suggest it - after reviewing whet we got so far16:46
DocScrutinizer05what16:46
wpwrakDocScrutinizer05: you mean the -devel list ? yup17:05
DocScrutinizer05fine17:05
DocScrutinizer05maybe you want to /join #neo900 too?17:06
Action: wpwrak stretches the screen a little ...17:07
whitequarkwhoa, interesting: https://www.privacyinternational.org/blog/what-does-gchq-know-about-our-devices-that-we-dont18:31
whitequarkGCHQ destroyed the keyboard, trackpad controllers and *inverter* on the motherboard of their computers18:31
whitequark(while erasing the snowden's cache from them)18:31
DocScrutinizer05meh, fools. Don't they see that it's not about the *original* chips but about some fake that acts as keylogger or storage device in addition to the generic (e.g.) keymatrix decoder? It's completely nonsensical to investigate what can get stored on a usual keyboard controller, the question for GCHQ been if it maybe was more than just a keyboard controller19:35
DocScrutinizer05I bet the monitor also been attached via USB in addition to the usual VGA, or it used a HDMI or whatever, that also allows similar attaching of peripherals19:37
DocScrutinizer05whatever they call "inverter", I don't care to much, given the ignorance they expose by approaching this investigation19:38
DocScrutinizer05>>Due to the generality of this component, it is difficult to ascertain what role this plays in the overall operation of the device, however we believe this component is similar in function to the chip described here.<< yep, exactly19:40
sb0_why did they damage the PCB in such as way though, instead of simply desoldering the chip?19:40
DocScrutinizer05rather interesting however is that GCHQ thinks they can destroy data by destroying hardware.What makes them think there's no copy anywhere19:41
sb0_the trackpad chip (it's supposed to be a 2Mbit SPI flash) and the inverter are easier to desolder than to mill19:41
sb0_maybe they're just trolling us ;)19:42
DocScrutinizer05sb0_: do you really think they had a good reason and rationale for that activity?19:42
DocScrutinizer05of course they are trolling19:42
DocScrutinizer05trolling the guardian19:42
sb0_"let's just damage some chips to show we've done some voodoo"?19:42
DocScrutinizer05let's just damage some stuff at "the guardian" to let them know we can do that19:43
DocScrutinizer05they sent their cleaner team which did a proper job of destroying everything that might have a storage built in - not per default off the shelf but technically, by somebody who wantsa to hide such storage19:44
whitequarkDocScrutinizer05: yeah, that's the consensus of my... ahem, twitter stream as well19:45
DocScrutinizer05so: all USB attachable devices, all devices attached to any other data bus, all storage devices of course19:46
whitequarkhm19:46
whitequarkfirst, I am not high. second, I think that our solar system and my vacuum cleaner are markedly similar in some qualities19:46
DocScrutinizer05and probably they weren't even very religious about it since they knew the guardian has copies anyway19:47
whitequarkor rather, I think you can model curved spacetime with air, some shit floating in it and movement of it, instead of the boring old rubber-table-and-steel-ball thingy19:48
whitequarkI've seen this air stream do some funky things like take a particle and accelerate it immensely rather than vacuuming up19:48
whitequarkand also it bends streams of running water in a really fascinating way19:48
DocScrutinizer05wait till it sucks up the water, this will get really funny19:49
DocScrutinizer05I doubt your first statement ;-P19:49
whitequarkit was actually my first idea for addressing the "flood" in "flood coolant"19:49
whitequarkinstead of, I dunno, placing a bucket under the table19:50
whitequark1) the vacuum cleaner sucks up water *really* well19:50
whitequark2) it turns it into fine mist that goes through all filters19:50
whitequark3) suddenly you have a lake in your room19:50
whitequarkoddly, the vacuum itself doesn't really seem to mind such treatment19:50
whitequarkI also tried connecting its inlet to its outlet and pouring water in it, but it doesn't seem to form a loop very well19:52
whitequarkI think I have to restate that I'm not high, I'm just curious19:52
DocScrutinizer05did you ever place a PC under water, out of curiosity how well that works?19:55
DocScrutinizer05what did you think where the water is supposed to stay, given that's a usual dry-vacuum that doesn't have any sort of a tank for the water?19:56
DocScrutinizer05btw it's amazing how long it takes until a usual motor running at 220V AC will desintegrate and break when operated under water19:57
whitequarkI take it you've checked that experimentally? :D19:58
whitequark(PC) not. not yet19:59
DocScrutinizer05can take days until electrolytic effects destroyed the cables or other parts, or the bearings go rotten19:59
DocScrutinizer05but for sure they eventually will19:59
whitequarkhmm19:59
DocScrutinizer05I suggest you use a usual bucket with lid (often used to sell e.g. 10L of soap in it, or similar) and cut a hole into middle of the lid for vacuum, and a second hole at the outer end of the lid for a tube that sucks your water into the bucket20:07
DocScrutinizer05ideally the tube is bent or mounted in a way so it gives a circular momentum to whatever goes into the bucket20:08
DocScrutinizer05so air and water is spinning along the inner side of the bucket, thus separating water from air20:08
DocScrutinizer05I again doubt your statement about being high :-)20:09
DocScrutinizer05maybe some solvents or whatever? ;-)20:09
DocScrutinizer05you're still alive? or already electrocuted by a vacuum cleaner filled with water?20:12
DocScrutinizer05also beware of oxyhydrogen gas!20:13
Action: DocScrutinizer05 starts to worry20:16
DocScrutinizer05whitequark: did you test the PC now?20:20
whitequarkDocScrutinizer05: was doing some shit21:24
whitequarkI mean, I was milling out the water collector suggestion I elaborated to wpwrak earlier21:24
whitequarkwpwrak: http://imgur.com/sv9UYzx so this is the kind of finish I get at 250mm/min21:25
whitequarknot too bad eh?21:25
whitequarkcould probably get it better by going even slower, but I'm impatient21:25

whitequarkwhat the FUCK is wrong with you linux21:27
wpwrakambient radiation too hard for the RAM ?21:27
whitequark$ uptime 01:27:44 up 46 days21:27
whitequarknot bad for a laptop. maybe ambient radiation, yes21:28
wpwrak(finish) looks nice21:28
whitequarkand this is the, uh, setup I made to make that: http://imgur.com/a/EFCuR21:28
whitequarkthe pump is a russian-made one, a spare part for Moskvich (a russian car)21:29
whitequarkit stands in a container because its case broke within 5 minutes when I first ran it, and it leaks water like crazy21:29
whitequarkwhich was, frankly, not surprising21:29
wpwrak(car pump) then we know the origin of the radiation :)21:30
whitequarkthe keyboard is NOT soaked in water, it stands about 2cm over the, uhhh, river21:30
wpwrak;-))21:31
wpwraklet's codename your setup "crazy ivan" :)21:32
whitequarkwe could give it a typical russian military codename, say, "Chrysanthema"21:34
whitequarkor "Pinocchio" (I shit you not, it's an actual one, for this: http://www.capital.ua/uploads/news/2014/05/08/e055b1a682b7fb5c987fdc9903ef12a15f9b20e9.jpg)21:35
whitequarkthere's also handcuffs "Tenderness"21:35
wpwraki think in WW2 these were called "stalinorgel" by the germans (stalin's organ, where organ = musical instrument)21:36
wpwrak(tenderness) hmm. https://plus.google.com/102512865795399405593/posts/6UTZZaiVg2E21:38
whitequarkabout right21:38
whitequarkwe also have a police baton "Argument"21:39
whitequarkand a few more in that vein21:39
wpwrak"convincer" ;-)21:40
DocScrutinizer05"lart" been too geeky, I guess21:56
DocScrutinizer05btw is this normal that those imgur photos take ~30s with 100% on one core to render?21:57
DocScrutinizer05do they decompress jpg in javascript now?21:59
whitequarkDocScrutinizer05: no, I just take them in highest resolution my camera can22:08
whitequarkit takes ~a second to decode with (ridiculously overoptimized) chrome on (ridiculously overpowered) ivy bridge cpu22:08
whitequarkimgur really oughta to make thumbnails22:08
whitequarks,to,,22:08
Action: whitequark sighs22:09
whitequarkfuck this is hard22:09
whitequarkspeeds and feeds are hard, proper fixturing is hard22:09
wpwrakthere's a reason why we call it "hardware" :)22:10
whitequarkfucking wood growing due to absorbing water and screwing up my Z calibration and making endmill go too deep and breaking six of them is too fucking hard22:10
whitequarkfuck it is 2am22:10
whitequark(o°¡°o5 ;;22:10
whitequarkI should buy endmills in bulk or something22:10
whitequarkthese chinese guys probably will give me a discount for a 100022:10
whitequarkthe problem is that the 1.5mm endmill is quite sturdy, e.g. it can do aforementioned 1200mm/min in acrylic22:11
whitequarkbut the inner corners are WAY too roundy22:11
whitequarkand 1.0mm is really weak, you've gotta do no more than 250mm/min and not plunge it more than .8mm layer at a time22:11
whitequarkthe inner corners still suck, but somewhat less22:12
whitequarkand I can't find a fucking file to make corners straight in the entire moscow, the only one I could find is flat, and I need one with rectangular section22:12
whitequarkI'm going to go sleep before I start RANTING IN ALL CAPS22:13
whitequarkhm, this looks ok: http://zubr.uragan-instrument.ru/nabor-nadfilej-16021-2-H10.html22:15
