2015-02-13 18:40 welder that uses a tungsten electrode in inert gas (argon) 2015-02-13 18:40 you need that for stainless 2015-02-13 18:40 and most vacuum stuff is made from 316L 2015-02-13 18:42 oh damn.. i only wonder how you get all this stuff with the current rate exchange :) 2015-02-13 18:42 I'm paid in USD :p 2015-02-13 18:42 very clever :) 2015-02-13 18:43 the welder cost 7000 RUB (some discount). mask, 2000 RUB. 9th torch, 3000 RUB 2015-02-13 18:43 the biggest issue was finding 316L filler rods in qty of less than 5kg. 5kg of those cost like a whole new welder 2015-02-13 18:44 argon is insanely cheap. 300 RUB ($5 for everyone else) for a 10L cylinder 2015-02-13 18:44 I'm told it costs at least an order of magnitude more overseas 2015-02-13 18:44 had to google some of the stuff.. you couldn't get 316L is russia? 2015-02-13 18:45 I could easily get them in 5kg boxes 2015-02-13 18:45 it took two days to find a local place that sells you them one by one 2015-02-13 18:45 same for TIG torch accessories, really, but the rods are really fucking expensive 2015-02-13 18:46 now the last part I need is some source material, which proves most problematic of it all 2015-02-13 18:46 no one wants to sell someone a 20x20cm square of 316 2015-02-13 18:47 i guess it could rise suspicion :) 2015-02-13 18:47 huh? why? 2015-02-13 18:47 it's just more economical, and I guess more lazy, to sell huge 2x3m sheets 2015-02-13 18:48 ehm, why not? i, the person "from outside", don't see a single reason why you would want a 20x20 piece of metal 2015-02-13 18:49 my next question was - what were you going to do :) 2015-02-13 18:49 and why would that be of any concern to you? 2015-02-13 18:49 nah, not to me.. 2015-02-13 18:49 behold, the most toxic of all USSR mentality, in the chat right next to you 2015-02-13 18:50 if a person does something you could not think of, they must be doing something /weird/! they must be crushed before they actually have a chance at success! 2015-02-13 18:53 that's quite right 2015-02-13 18:53 it's actually quite telling that the people actually selling me shit have /never/ asked what i want it for. they either sell or decide it's not worth it for them 2015-02-13 18:53 it's always the 'policymakers' who get these ideas 2015-02-13 18:53 can't make anything, make a policy, i guess 2015-02-13 18:53 let's put it aside, what are you doing right now?

What's it for? 2015-02-13 18:56 I actually have no idea how it's called in russian 2015-02-13 18:57 wonder what did you even get from GT 2015-02-13 18:57 reading https://ru.wikipedia.org/wiki/%D0%9C%D0%B0%D0%B3%D0%BD%D0%B5%D1%82%D1%80%D0%BE%D0%BD%D0%BD%D0%BE%D0%B5_%D1%80%D0%B0%D1%81%D0%BF%D1%8B%D0%BB%D0%B5%D0%BD%D0%B8%D0%B5 2015-02-13 18:57 that's quite right 2015-02-13 18:59 it's mainly to do something simple to get a hang of vacuum tech, before I move on to more complex topics 2015-02-13 18:59 but this can be useful on its own merit 2015-02-13 18:59 DIY LCDs! 2015-02-13 18:59 wow, that's insane 2015-02-13 19:00 I don't actually know how to make the glass-lcd-glass sandwich 2015-02-13 19:00 not a glass sealed one like they make in the indsutry at least 2015-02-13 19:00 but electrodes would be doable. 2015-02-13 19:00 just reading this article alone, i can't get impression how this could be doable by a single person 2015-02-13 19:00 oh, it's fairly trivial 2015-02-13 19:00 I already have a prototype, it just kinda desolders itself when I run it for more than five minutes 2015-02-13 19:01 -)) 2015-02-13 19:01 https://www.youtube.com/watch?v=c4Sic1DRXJI has an incredibly crude and dangerous variant 2015-02-13 19:01 also no argon, so the films are all oxidized to hell 2015-02-13 19:02 but that one can be built using a dumpster and determination 2015-02-13 19:02 I have a proper MOSFET-based power supply and feedback for process control 2015-02-13 19:02 and a nicer chamber, soon 2015-02-13 19:02 ok ,so what's your end mission anyway? 2015-02-13 19:03 short term, I want to make a GC-MS 2015-02-13 19:03 it requires some impressive chamber making skills, and somewhat less impressive HV RF power supply skills 2015-02-13 19:03 specifically a QMA-based MS 2015-02-13 19:04 I've had a productive conversation with a guy who makes those for a decade or two, I have a good idea of what electronics will I need 2015-02-13 19:04 chamber, not as much so, but should be doable 2015-02-13 19:06 long term, CMOS ICs. it'll actually require sputtering (those metal gates!), and RIE, and CVD (both of which use really similar equipment to a sputterer), and a QMA (without the GC part), and a bunch more things 2015-02-13 19:07 oh, man, too much for me to google.. so you want to make device to analyze what is contained in a given sample of matter? 2015-02-13 19:07 yeah 2015-02-13 19:07 veryfancy! 2015-02-13 19:07 it's not a star trek tricorder 2015-02-13 19:07 because it requires fairly complex and extensive calibration 2015-02-13 19:07 but it's a very useful device 2015-02-13 19:08 is it for your own entertainment or is it your work project? 2015-02-13 19:08 entertainment 2015-02-13 19:08 does it matter what to analyze (gas, liquid, etc? ) 2015-02-13 19:09 well, the mass spectrometer works with ions 2015-02-13 19:09 kyak: i guess at work he builds wormhole generators ... 2015-02-13 19:09 ionization is actually a topic unto itself 2015-02-13 19:09 you could ionize gases, or vaporized liquids 2015-02-13 19:09 or you could smash ions into a surface, and sputter some ions 2015-02-13 19:09 called secondary ion mass spectrometry 2015-02-13 19:10 whitequark: so you need to take action on that matter? like, ionieze it? 2015-02-13 19:10 v. useful for analyzing the "slices" of surfaces 2015-02-13 19:10 like the exact composition of an oxide film on steel, shit like that 2015-02-13 19:10 yeah 2015-02-13 19:10 in a GC-MS you get a gas inside the spectrometer 2015-02-13 19:10 usually you vaporize a liquid. the GC column is held at 100-200°C 2015-02-13 19:10 wpwrak: whatever he builds, i only hope it works for good of mankind: )) 2015-02-13 19:11 wpwrak: lolnope. smartphone apps 2015-02-13 19:11 and until recently, websites on ruby on rails 2015-02-13 19:11 like that --^ :) 2015-02-13 19:12 whitequark: ok, cosindering i only understand 10% of what you say, it's still very interesting. how the hell is this entertaining? 2015-02-13 19:13 fmeerkoetter has joined #qi-hardware 2015-02-13 19:13 i guess the real objective is to have a talk for the next EHSM. the sort of talk that will discourage all further submissions :) 2015-02-13 19:13 converse question, how the hell is any of shit people usually find entertaining is not boring as hell 2015-02-13 19:13 i mean, entertaining is good, but doing real profit in production/ whatever? 2015-02-13 19:13 well 2015-02-13 19:14 these skills are quite rare, much more so than your typical webdev shit 2015-02-13 19:14 and they are valued well if you know the right people 2015-02-13 19:14 but this is not why i work on it 2015-02-13 19:14 wpwrak: actually inspired by EHSM here 2015-02-13 19:14 met the MS guy at EHSM 2015-02-13 19:15 i'm telling you, this shit is valued, "even" in russia :) 2015-02-13 19:16 people doing this stuff in russia are stuck a few decades ago 2015-02-13 19:16 hell, the MS guy (from Poland, which is ex-USSR) was surprised when I showed him that you can /simulate circuits on a computer/ 2015-02-13 19:17 quote: "wow, you can do that?!" 2015-02-13 19:17 still the wikipedia article mentiones some "soviet time" publictions 2015-02-13 19:17 well, warsaw pact 2015-02-13 19:17 yes, there was quite some impressive work done 2015-02-13 19:17 but i mean. these people still consider a turbomolecular pump 'too complex' and 'new' and 'expensive' 2015-02-13 19:18 and sit on their crappy oil diffusion pumps 2015-02-13 19:18 which are just... i don't know why would anyone ever want to use that 2015-02-13 19:19 fmeerkoetter has quit [Ping timeout: 264 seconds] 2015-02-13 19:19 yep, i don't know what you are talking about, but i understand what you mean 2015-02-13 19:19 still, i'm seeing sometimes (by the duties of me job) people and organizations who are doing very crazy things 2015-02-13 19:20 I don't doubt that, I have seen it 2015-02-13 19:20 but also things that are heroic only if you pretend it's still 1970 2015-02-13 19:20 pcercuei has quit [Ping timeout: 250 seconds] 2015-02-13 19:20 that, too 2015-02-13 19:21 pcercuei has joined #qi-hardware 2015-02-13 19:22 have you /seen/ the welding equipment that /still sells/? 2015-02-13 19:22 they use a 200-kg rectifier and a 100-kg rheostat to control current 2015-02-13 19:22 to do the job that a 10kg IGBT-based inverter does much better 2015-02-13 19:22 they /still manufacture those anew/ 2015-02-13 19:22 whitequark: i'm wondering, why don't you find a job that satisfies you both mentally and financually? I mean, some doing some ruby shit for money and crazy state-of-the-art the entertainment? 2015-02-13 19:23 just doesn't make sense... 2015-02-13 19:23 because i have attention span of a fruit fly and i don't want my financials to be dependent on whether i get bored with the cool thing i came up with yesterday 2015-02-13 19:24 and ruby shit is already boring to the extreme, it can't get any worse by design 2015-02-13 19:24 that's half the reason. 2015-02-13 19:24 the second half is that current state of the art requires years of investment just to get up-to-date 2015-02-13 19:24 and it pigeonholes you into a specific position in specific industry 2015-02-13 19:24 whereas as it is, i'm free to go as wide as it pleases me 2015-02-13 19:25 it'll be /nowhere/ near state of the art 2015-02-13 19:25 ever 2015-02-13 19:25 because state of the art means hundreds of people 2015-02-13 19:26 so it's you personal freedom that's more important? 2015-02-13 19:26 i suppose? if it's going to be for fun 2015-02-13 19:27 also, ruby pays well. my last job (pre-crisis) was 90kRUB net 2015-02-13 19:27 in a place that does cutting edge research in RU they'll give you twenty if you're lucky 2015-02-13 19:28 that's a choice between rent and food :] 2015-02-13 19:30 and getting to your question.. i don't know of those companies. But i know of companies who build atomic stations abroad, and that's pretty state-of-the-art - and also companies who are into military and space, and there are pretty fascinating things going on 2015-02-13 19:30 (atomic stations) lol 2015-02-13 19:30 state-of-the-art nuclear plants are /literally/ based on 1970s design 2015-02-13 19:31 because of regulatory inanity 2015-02-13 19:31 and space, really, too, compare what SpaceX does with what NASA did 2015-02-13 19:32 you are not even close to knowing what's going on in those high regulated industries (like medicine, aerospace, and nuclear) - but let me assure you, we are very solid there :) 2015-02-13 19:33 1970s design doesn't equal to bad 2015-02-13 19:33 i certainly hope so 2015-02-13 19:33 also, it's not true 2015-02-13 19:33 i mean, its not 70's design 2015-02-13 19:34 wolfspraul has quit [Quit: leaving] 2015-02-13 19:34 so, where's our LFTR reactors? :] 2015-02-13 19:34 let me google it for me :) 2015-02-13 19:35 ah, i don't know.. i'll try to ask when i have a chance 2015-02-13 19:35 as far as I'm aware, the problem is that regulatory requirements are evolved to pigeonhole old reactor designs 2015-02-13 19:36 which are good at producing weapons-grade plutonium and not good at not producing shit that takes billions of years to degrade 2015-02-13 19:37 there are real problems with LFTR, which could be solved with more research, who almost no one does, because even a better LFTR reactor isn't going to be approved for operation 2015-02-13 19:37 there is IEC61508 (which has according GOST) and also IEC 61513 which is followed here in RUssia.. and these regulations are definitely not from 70s 2015-02-13 19:39 they still favor the same old designs 2015-02-13 19:39 I don't know what happens in space, but I know that SpaceX lands their boosters and NASA or Energiya throw them in the dumpster 2015-02-13 19:40 and I really, really doubt that SpaceX made any fundamental breakthrough 2015-02-13 19:40 ah! actually, not at all. Those standards are pretty generic and they support many design workflows. Including modern, such as model-based design 2015-02-13 19:40 I don't know further details from this point but this is a fairly common complaint by engineers from industry, so you'd have to find someone more educated than me 2015-02-13 19:41 that's a fair complaint 2015-02-13 19:43 if viric happens to visit us sometime, i'll be eager to tell you more :) 2015-02-13 19:44 pcercuei has quit [Quit: leaving] 2015-02-13 19:56 Nik05 has quit [Remote host closed the connection] 2015-02-13 19:59 Nik05 has joined #qi-hardware 2015-02-13 20:06 hi 2015-02-13 20:06 damn it, publicbt does not tell their own url in their website 2015-02-13 20:06 http://publicbt.com/ 2015-02-13 20:32 fengling has joined #qi-hardware 2015-02-13 20:36 fengling has quit [Ping timeout: 246 seconds] 2015-02-13 20:49 whitequark: you're incredible :-D 2015-02-13 20:50 Do you know how to embed a DTB into a kernel? 2015-02-13 20:50 isn't there a kernel config option for that? Does it really have to be done manually? 2015-02-13 20:50 a device tree blob, or whatever it's called 2015-02-13 21:50 DocScrutinizer05: I'm really bored, mostly 2015-02-13 22:01 either I answet "that's self evident" or I answer "can't believe that, seeing what you do all the time" 2015-02-13 22:03 arhuaco has quit [Ping timeout: 252 seconds] 2015-02-13 22:03 viric: pcercuei added DT support in our kernel in these two commits: https://github.com/gcwnow/linux/commit/b1384b76 and https://github.com/gcwnow/linux/commit/a9a9a68d 2015-02-13 22:04 it seems that you add the DTB file as a dependency in one of the Makefiles and the kernel build will generate it for you then from the DTS file 2015-02-13 22:05 graet! 2015-02-13 22:05 that is, great! 2015-02-13 22:15 arhuaco has joined #qi-hardware 2015-02-13 23:58 mth: what Makefile?
