#qi-hardware IRC log for Monday, 2013-11-25

larscbest is to send a patch that fixes the problem ;)14:25
pcercueiif I can find it, yes14:25
pcercueibut I have no serial line soldered so I can't even see the beginning of the call trace of the kernel panic14:26
larscotherwise always send the mail to both the maintainer and the mailinglist14:26
wpwraknice visualization (the link is kinda self-explaining): http://mattmckeon.com/facebook-privacy/18:49
viricwpwrak: the trend is to provide links with random-like strings22:18
wpwraki kinda like the old-school way of doing things :)22:33
DocScrutinizer05wpwrak: you seen my comments on anelok?22:50
DocScrutinizer05aah i missed your answers22:52
DocScrutinizer05wpwrak: (belt stickytape) however I meant with paint on inside, and that could look pretty cool when you use thin high glossy black tape22:54
DocScrutinizer05or even Alu stcky tape22:55
DocScrutinizer05can#t see how this would look crappy or cheap22:55
DocScrutinizer05for the sandpapering and polishing of milled inner side of windows, I already wondered how the hell you gonna accomplish that22:56
DocScrutinizer05high transparent acrylic varnish, rather than sandpaper and polish paste?22:57
DocScrutinizer05for the inside of the window, that is22:57
DocScrutinizer05heck, maybe even silicone oil to directly bridge the air gap to the OLED display?22:58
DocScrutinizer05depending on optical "density" of the materials, this might result in a 100% clean and transparent view to the OLED pixels22:59
wpwrak(tape) don't forget that there are two walls at that place: the half-case and then the other. the inside of the inner wall is painted black. the problem is that the outside of the inner wall and the inside of the outer wall are rough and reflect light.23:01
wpwrak(display) the problem isn't the air gap but the roughness of the inner surface. some oil would probably solve that, but then i'd have to worry about oil leaks :)23:02
DocScrutinizer05what are you talking about now? the display window or the "belt"?23:02
wpwrak1st was the belt. 2nd was the display23:02
DocScrutinizer05(belt) you won't see any of that anyway?23:03
DocScrutinizer05since the tape covers it23:03
wpwrakso the tape would be on the outside ?23:03
wpwrakah, but then it would be very noticeable. i mean, even paint is quite noticeable23:04
DocScrutinizer05just like packaging tape across the flaps of a paper box23:04
wpwrakeven the nice and shiny one :)23:04
wpwraknaw, it's tape on some extremely smooth plastic23:05
DocScrutinizer05yes, the idea is it's looking so nice it MUST be noticeable23:05
wpwrakeven dust looks like a mountain there ;)23:05
DocScrutinizer05I'm talking about extremely thin and high glossy black foil stickytape23:06
wpwrakhmm, and where would i find that ?23:06
DocScrutinizer05I couldn't think of a shinier surface23:07
DocScrutinizer053M? Scotch?23:07
DocScrutinizer05Silver one is probably even easier to find23:07
DocScrutinizer05for black one I can only think of stickers at bottom of every other PSU etc23:08
DocScrutinizer05usually black with silver printing on it, actually completely silver though with black printing23:08
DocScrutinizer05they are typically the thickness of the brown packing tape "tesa paketband"23:09
wpwrakmmh, my question is more about which industry supplier may have such tapes. they're certainly not the sort you find at the stationary shop23:09
DocScrutinizer05yes, you need to google a bit for such stuff23:10
DocScrutinizer05probably you could order it at label printers23:10
DocScrutinizer05or similar suppliers23:10
DocScrutinizer05generally sticker/label manufacturers23:11
DocScrutinizer05deco shops might also have such stuff23:11
wpwraki don't see such stuff around here. even finding decent double-sided tape is kinda difficult23:12
wpwraki can imagine what you're talking about, though :)23:12
DocScrutinizer05well, you probably need to order it via internet then23:12
wpwrakhm, i think i'll try to get things done with the "white" band. for the y-box, a tape may indeed work (if i can find it). but the anelok prototype, needs to be opened from time to time (battery and memory card change). a tape would make this messy.23:15
DocScrutinizer05http://www.kohlstaedt.de/technologien/frontfolien.html?gclid=CPXV5peIgbsCFQ1L3god6A4AzA    http://www.living3000.de/shop/suche?q=folie%20deko&campid=533733795823:16
wpwrakbut it's good to have another fallback solution, because the ones i've tried this far don't convince me23:16
DocScrutinizer05yeah, this solution is not meant for any "user serviceable parts inside"23:17
wpwrak"Wand-Deko Gothic-Haus" hehe ;-)23:17
wpwrak"Plotterfolie": impressive range of surfaces23:19
wpwrakif all else fails, i can always use electrical tape :)23:21
DocScrutinizer05that looks really crappy and dull23:22
DocScrutinizer05particularly non-plane surface, it has amazing "impurities"23:22
DocScrutinizer05and way too thick23:22
DocScrutinizer05I think scotchtape is about maximum thickness you could use before it gets nasty where the tape's edgets are exposed23:23
DocScrutinizer05unless you use 15 layers and it adds up to a solid 0.7mm belt around the whole thing ;-)23:24
wpwrakit gets thinner when you stretch it :)23:24
wpwrak(the electrical tape)23:24
DocScrutinizer05yeah, and smaller23:24
wpwrakbut yes, very dull23:24
DocScrutinizer05well, I'm undecided if I even should suggest it since I think it might look crappy as well: there is that 0.1mm pure alu sticky tape23:26
DocScrutinizer05you can find that at Conrad et al23:27
DocScrutinizer05or maybe use copper instead of alu? ;-P23:27
DocScrutinizer05at least the alu tape you could cut open the device with a sharp cutter again, splicing the tape in the middle into two smaller halves23:29
DocScrutinizer05would create a rather clean gap between your case upper and lower half23:29
wpwraknaw, the tape, if there's to be any tape at all, should be invisible23:30
DocScrutinizer05that's not possible23:30
DocScrutinizer05it will be always visible23:30
wpwrakbut i think i can get an okay effect with just avoiding paint on the "belt". it looks fine if it's consistent. just looks bad if it comes and goes.23:31
DocScrutinizer05and the whole purpose is it actually *is* visible, so it can cover the nasty parts along your "collision" zone between upper and lower half of case23:31
wpwrakyes, tape will always look as something added. while some odd color change on the inside can look intentional :)23:32
wpwraki.e., "DON'T make it look like an accident" ;-)23:32
DocScrutinizer05really shiny belt might look like the icing on top of the acrylic design23:32
DocScrutinizer05brushed alu would look really nice23:33
DocScrutinizer05exact height of the case, ending flush on top and bottom acrylic transparent surface with that black inside it23:34
wpwrakyeah, pretty and quite impossible :)23:36
DocScrutinizer05the glossy alu stickytape might work as well, but probably won't have a proper surface23:36
DocScrutinizer05impossible? how?23:36
wpwrakif it's flush with the edge, then it'll also be exposed to friction. so it'll separate very quickly23:36
DocScrutinizer05get some of that sturdy alu sticky23:37
wpwrakoh yes. i wouldn't even want paint at the place. maybe epoxy paint, which is nearly indestructible. but then i don't have the tools for that.23:37
DocScrutinizer05ok, when I get really bored, I will search for my alu sticky and a matchbox and show you what it could look like. But not this week23:39
wpwrakhehe :) i made cases with paint on the inside, on the outside, and mixed, and the difference is just enormous. with the paint on the inside, it looks almost like some iJunk ;-)23:42
DocScrutinizer05btw when you're extremely worried about the tape edges exposed, do a 0.2mm recession from top-1mm til bottom+1mm all around the case23:42
wpwraki can't do recessions with that sort of precision23:42
wpwraki often have to sand off some 0.5 mm of horizontal mismatch. it's weird, since all the rest is much better. but on the outside, weird things happen. probably the parts are too small for the fixing tape to hold them in place well enough.23:44
DocScrutinizer05use magnets23:45
wpwraki was more thinking of the pressure coming from some neutrino flow :)23:46
wpwraklet's say, generated by vaguely waving my hand above the mill23:47
DocScrutinizer05yeah, pretty hard to build such stuff when the shops not even have ds-sticky and probably no decent workbench in vicinity23:52
DocScrutinizer05I'd probably contact my carpenter friend, he's used to planing and milling to the 0.1mm precision23:54
DocScrutinizer05I heard in USA the required precision is ~5mm23:54
DocScrutinizer05I'd build me a 2 or 3 fixtures where the part fits in tightly23:58
