I don't think so :/ 22:14 < kanzure> (but otherwise he's of course, awesome) 22:20 < gene_> hmmmm... 22:20 < gene_> found a russian CNC machine that cost $428 22:21 < kanzure> where are you getting that money? 22:23 < kanzure> fenn: can we get dan heeks, thomas paviot, jelle feringa into this channel or om by any chance? the likelihood seems slim :/ 22:24 < gene_> http://translate.google.com/translate?prev=_t&hl=en&ie=UTF-8&u=http%3A%2F%2Fwww.mntc.ru%2Fwiki%2Findex.php%2F%25D0%259C%25D0%25BE%25D0%25BB%25D0%25BE%25D0%25B4%25D0%25B5%25D0%25B6%25D0%25BD%25D1%258B%25D0%25B9_%25D0%25BD%25D0%25B0%25D1%2583%25D1%2587%25D0%25BD%25D0%25BE-%25D1%2582%25D0%25B5%25D1%2585%25D0%25BD%25D0%25B8%25D1%2587%25D0%25B5%25D1%2581%25D0%25BA%25D0%25B8%25D0%25B9_%25D1%2586%25D0%25 22:24 < gene_> B5%25D0%25BD%25D1%2582%25D1%2580&sl=ru&tl=en&history_state0= 22:25 < gene_> that's what ECM is capable of 22:26 < fenn> kanzure: heeks certainly, other guys probably not 22:27 < fenn> that is the longest, ugliest URL ever 22:27 < kanzure> huh, appropedia is one of the top 10 most followed twitter accounts in North America 22:27 < kanzure> gene_: http://tinyurl.com/ 22:27 < gene_> I don't do tinyurl 22:28 < kanzure> then do something else 22:28 -!- ybit [n=heath@unaffiliated/ybit] has joined #hplusroadmap 22:29 < kanzure> fenn: paul puts it well in his latest email: "a conflict of interest" in those who are hoping to make OM deliver them goods *right now* 22:29 < fenn> nooo 22:29 < fenn> i already put my 4 hours of openmanufacturing in today 22:29 * fenn cries 22:30 < kanzure> 4 hours? 22:30 < gene_> http://www.mntc.ru/wiki/index.php/%D0%9F%D1%80%D0%BE%D1%81%D1%82%D0%B0%D1%8F_%D1%88%D0%B0%D1%80%D0%B8%D0%BA%D0%BE%D0%B2%D0%B0%D1%8F_%D0%BD%D0%B0%D0%BF%D1%80%D0%B0%D0%B2%D0%BB%D1%8F%D1%8E%D1%89%D0%B0%D1%8F 22:30 < gene_> interesting 22:31 < kanzure> gene_: please run that through javascript:urldecode() before pasting again. 22:32 -!- elias` [n=me@unaffiliated/elias/x-342423] has quit [Read error: 145 (Connection timed out)] 22:33 < gene_> hahaha, this russian CNC machine I'm looking into can operate in sub-zero conditions 22:38 < fenn> FUCK 22:38 < fenn> now google doesnt even AND all the search results together 22:38 < fenn> they just couldn't let it be.. 22:39 < fenn> i give it another 3 months before they remove the functionality entirely in the name of stupidity 22:40 < gene_> huh? 22:40 < fenn> foo +bar 22:41 < fenn> results won't necessarily have bar unless you add + 22:44 < kanzure> I think Google transitions certain users over in bulk or something, but in batches 22:44 < kanzure> because some people experience new features, others don't 22:44 < kanzure> foo +bar insensitivity happens for me too. 22:44 < fenn> yeah did you know amazon price is different depending where your ISP is? 22:45 < fenn> so they can extract the most money out of you 22:45 < kanzure> lovely. 22:46 < kanzure> but that could just be done by currencies. 22:46 < fenn> i mean it changes by zip code 22:47 < gene_> http://tinyurl.com/cv6aov 22:47 < gene_> looks like we have a way to make sharpie microfluidics acurately 22:48 < fenn> gene a couple days ago you were in #emc asking about something.. what was that about? 22:49 < fenn> that ball guide is icky 22:49 < fenn> corners don't make good bearing surfaces 22:50 < gene_> that's not a ball guide 22:50 < fenn> well whatever it is 22:52 -!- ybit [n=heath@unaffiliated/ybit] has quit ["Lost terminal"] 22:52 < fenn> i like this construction method (perhaps not suitable for just scratching in sharpie ink) http://buildyourcnc.com/mickhcnc.aspx 22:52 < gene_> it's some sort of reconfigurable russian CNC machine 22:53 < gene_> http://tinyurl.com/cv6aov 22:53 < gene_> wait a second 22:53 < gene_> you see a ballguide 22:53 < gene_> hmm 22:53 < fenn> By developing low-cost linear guide for the designer "Kulibin" We try a lot of designs. On one of them we describe in this article, because It seems that this is an easy-to-manufacture design of ball guide 22:54 < gene_> that's not what I wanted to show you 22:54 < fenn> pic of sandwiched acrylic and aluminum with ball bearings in the gaps 22:55 < gene_> well what I wanted to show you was a DIY micromanipulator 22:56 < gene_> http://tinyurl.com/asoosx 22:57 < gene_> this is better, it's the russian CNC machine 22:57 < gene_> real cheap $428 for a kit 22:58 < fenn> they use stepper motors as thrust bearings. not good 22:59 < gene_> huh? 22:59 < fenn> http://www.mntc.ru/wiki/images/e/e7/9401.jpg 22:59 < fenn> see how the threaded rod goes right onto the stepper with nothing between 23:00 < fenn> that means it's pushing on the motor's bearings 23:00 < fenn> they arent designed for that, and will give a lot of slop (backlash) 23:00 < fenn> which is a big deal if you are trying to do things at small scales 23:00 < fenn> especially because it's not predictable with plain bearings (bushings) 23:01 < gene_> http://tinyurl.com/dbcv87 23:01 < fenn> would you really pay $428 for that? 23:01 < gene_> I see you have a point there 23:01 < gene_> it looks like the type of thing you could make from parts from home depot 23:02 < gene_> oh wait, home depot doesn't sell metric parts 23:02 < fenn> don't use metric parts then 23:02 < fenn> i'd at least want proper square grid beam 23:03 < gene_> the thing that is cool about this russian design is it's versatility 23:03 < gene_> and that it breaks down quite easily 23:03 < fenn> what is the foil supposed to do? 23:03 < gene_> huh? 23:04 < fenn> for the probe 23:05 < gene_> russian design what do you expect 23:43 -!- willPow3r [n=will@cpe-66-75-6-181.san.res.rr.com] has joined #hplusroadmap
