wpwrakwhitequark: btw, would be nice to have a shortcut for editing group names from the list of groups, without having to select the group, edit there, then return08:59
wpwrakhmm .. no autosave before the first "save as" ? just crashed on me :(09:11
wpwrakwhitequark: now, a very simple problem: i want to make a box for a display. i start with the sides: i draw the module rectanglt (as construction), then with a little offset the inside of the side walls, and with another offset their outside. extrude, all fine.09:31
wpwraknext, the top. there i put a workplane on the top of the walls, make one rectangle, extrude, set thickness. couldn't be easier.09:32
wpwraknow, the window opening. for this i go back to the sketch with the walls since they have the geometry of the actual display. i add a new workplane on top, then construct a suitable rectangle, and extrude.09:34
wpwraknow, first problem: this should have the same thickness as the top, but when i select the top so that i can select its thickness, "home" disappears, so i can't go back to the group of the extruded window.09:35
wpwrak(i need to go to the group of the extruded window since part of the edges that define the thickness is hidden inside the top, and if i try to set a length (thickness) on what is visible, i just get a REF, if i set an equivalence, (of course) an error09:38
wpwrakbut okay, i can just set the length independently and slvs is happy. but then comes the real problem: when i set the window to "difference", nothing happens.09:39
wpwraki guess slvs applies the "difference" to the "parent", i.e., the side walls, which already have a big hole there, but not the whole model ?09:40
wpwrakthis is the bothersome critter: http://downloads.qi-hardware.com/people/werner/slvs/box.slvs09:47
whitequarkwpwrak: (shortcut for editing group names) ehhh... seems like too much clutter on the main display to me11:41
whitequark(no autosave before 1st save as) indeed11:41
whitequarkwhat was the crash?11:41
whitequark(bothersome critter) I see a few issues11:43
whitequarkin g002, you don't have a closed contour11:44
whitequarkso the extrusion in g003 fails11:44
whitequarkthe second issue is that you've put g006 after g003, this happens if you have created g006 after g003 was active11:47
whitequarkerm, s/after/when/ s/was/is/11:47
whitequarkso the order of booleans is "extrude walls" "remove the window" (from empty space) "extrude top"11:47
wpwrak(crash) i think that was when i was adding a point to the "window" sketch. quite unexpected. alas, didn't record the traceback, and it hasn't happened again.11:49
whitequarkwpwrak: I think I know what the crash was, pull from master11:54
wpwrak(g002) oh strange. thought it had worked. maybe it did before the crash, then failed in the 2nd try, but i didn't even pay attention. fixed, thanks !11:54
whitequarkanyway, the way you can fix this is by deleting g006 and activating g005 before creating it11:55
whitequarkso that you have something to subtract from11:55
wpwrakthe the order, i needed to select g003 to anchor the workplane, since i need the geometry from g003, not g00411:55
whitequarkhuh? how so?11:55
wpwrakerr no ...11:55
wpwraknot g005 i mean11:56
whitequarkthat still doesn't make sense11:56
whitequarkall of the geometry from g003 is present when g005 is selected11:57
whitequarkif you are having a hard time *selecting* it with a mouse, remove the "shown" check, "show solid model" and/or activate "draw invisible lines"11:58
wpwraknot the inner wall or the construction rectangle on the inside11:58
whitequarksure it is: https://imgur.com/a/PH0VE11:58
wpwrakah ... when toggling the cube, they eventually appear11:59
wpwrakkewl. that should work then. thanks !11:59
wpwrakbtw, is the list of groups really a linear list or a tree ? e.g. would a diff in my current g005 also affect g007 ?12:00
whitequarkyou could also set the construction stuff to some vibrant color: https://imgur.com/a/g0Wro12:00
whitequarkthe list of groups is a linear list12:00
whitequarkbut you can add groups in the middle, because that lets you avoid rebuilding the entire sketch in certain cases12:01
whitequarkunfortunately... that feature also seems to have added confusion, which is very unfortunate12:01
whitequark(vibrant color) especially once I fix the color selector bug.12:01
wpwrakheh :)12:01
wpwrakyou could solve some of the issues by supporting reattaching work planes :)12:01
wpwrakthat is, "moving"12:02
whitequarkfrom one origin point to another? yeah12:02
whitequarkI don't really know what UI to add for this yet, but it's planne12:02
whitequarkbtw we have #solvespace on freenode.net12:02
wpwrakah, let's use that then12:04
wpwrakjust-in-time delivery, updated: 3D print finishes just when DHL delivers the parts that go into the piece i printed :)15:31
strawberyargonairport security check advice?17:35
wpwrakstrawberyargon: don't carry water, guns, or weapons of mass destruction (samsung galaxy whateveritwas) :)17:37
strawberyargonwpwrak, what about this: https://transfer.sh/zd271/img-5521.jpg17:48
strawberyargonthe little lcd display will have numbers on it17:49
strawberyargonincluding a time remaining...17:49
strawberyargonthe numbers wont be changing when its not in use17:50
strawberyargoni need to take as carry on due to the battery. the box was ment to make it safer/"more professional". while i was at it i added extras on top of the little battery capacity monitor, hench time remaining17:51
whitequarkstrawberyargon: country?17:53
strawberyargonuk toLanzarote17:53
strawberyargonuk to #Lanzarote17:53
whitequarkto, uhm, one of the Canary Islands?17:54
strawberyargonwhere http://totalism.org/ is17:54
whitequarkok. i'm not really familiar with uk security and customs17:55
strawberyargonok then17:55
whitequarkit does sound like you may have to do some explaining17:55
strawberyargonoh no17:55
whitequarkpersonally I would put that into luggage and disconnect the battery17:55
whitequarkjust put the battery in carry-on17:55
strawberyargoni doupt they will notice the time remaining. its a smaller number17:55
whitequarkthe entire box is not exactly confidence-inspiring17:55
whitequarkalso not sure how interesting will it look on x-ray17:56
strawberyargonsigh... the box was supposed to protect battery during carry on...17:56
strawberyargonlooks like ya cant win when trying to comply with lithium batt rules17:57
strawberyargonyea a hard box17:57
whitequarkwhat sort of batteryis it17:58
strawberyargonso if its droped. the batt is already in a good old box.17:58
strawberyargonunder 100WH17:58
strawberyargonsafer than li-ion but the lithium rules dont recognise lifepo17:59
whitequarkI mean, the type of case17:59
strawberyargonits the same package as a 7AH lead acid18:00
whitequarkis it a 18650? a flat pack? something else?18:00
strawberyargonsee the pics18:00
whitequarkso this? http://upload.ecvv.com/upload/Product/201111/China_Sealed_lead_acid_battery_12V_7AH2011114942160.jpg18:00
strawberyargonthe links i spent to wpwark18:00
whitequarkah I see the other picture now18:01
strawberyargonthe one with the batt?18:01
whitequarkI would *definitely* put the battery in carry-on, wit properly insulated contacts18:01
whitequarkthat looks way less sketchy than your entire device18:01
strawberyargonadmitly its not finished yet18:02
strawberyargongot the hole to patch up18:02
wpwrakdisplay, counting down the time, and i even spot some red wire ! well, in guantanamo, they speak spanish, too :)18:02
whitequarkI don't think the counting down part is especially problematic, personally18:03
strawberyargoni dont wana go there, 18:03
whitequarkjust the entire device doesnt look very safe18:03
whitequarkthe "will it accidentally catch fire" issue more than "will it deliberately explode"18:03
wpwrakwhitequark: you don't go to the movies much, do you ? :)18:03
strawberyargonit be more tidy when finished18:03
whitequarkwpwrak: i fly a lot though18:03
whitequarkwith tons of weird shit on me18:03
wpwrakheh ;-)18:03
whitequarka few days ago I have suggested and successfully read the xray image to a customs official who wanted to inspect my luggage18:04
strawberyargoni just hope the staft are better than usa teachers (ref bomb clock kid)18:04
strawberyargonxray image?18:04
whitequarkthey xray your luggage to see if theres anything suspicious18:04
whitequarkhe looked at the screen and asked me to open my luggage, which would have been a pain18:05
strawberyargonsry, yea but how did you see the pic18:05
whitequarkso i instead asked him to show me the xray pic and explained exactly what all the weirdly shaped blobs were18:05
strawberyargonnice one18:05
strawberyargonmetel boxes?18:05
wpwrakwhitequark: i once went through airport security with two bottles of this in my backpack: http://mozart-spirits.com/de/produkt/mozart-chocolate-cream18:06
whitequarkphone, some hoses, a vise18:06
whitequarknext time I'm gonna try to memorize the positions of xray-opaque stuff in my luggage and read the xray *without* looking at the display, just for kicks18:06
strawberyargonits easier to take batts i thought it there part of packed with gear18:06
strawberyargonbetter print out the datasheet for the batt....18:07
whitequarkstrawberyargon: anyway i count uk in the same "police state" category as the us18:07
strawberyargoni dont like it here18:08
wpwrakwhitequark: the lady stared at her screen in disbelief, then asked if i had anything peculiar in my backpack. then i realized that this must have looked like this on her x-ray: http://www.freevectors.com/wp-content/uploads/2012/09/Bomb-Free-Vector.jpg18:08
whitequarkwpwrak: LOL18:08
strawberyargonif they dont allow the box on carry on can i put in my luguage or would it be too late by then? first time doing airtravel18:10
wpwrakthat's too late then. though they can just take things they simply don't want you to use during flight, and lock them up somewhere.18:11
strawberyargonaww had hope to use to it to extent laptop batt life :)18:15
whitequarkwpwrak: really? I've never seen that18:16
strawberyargonidk if there a socket on the plane?18:16
wpwrakwhitequark: i had it happen 1.5 times with insulin pens. those with the deadly 8 mm x a few microns needles. security found it, and handed it to the cabin crew, so that they could let me use it when i needed it for a meal, but would keep it at a safe place otherwise. so much the theory. of course, as soon as the door was closed, they brought me my pen.18:19
whitequarkwpwrak: oh, it happened with a necessary medical item. that's a different question.18:20
wpwrakthe 0.5 was similar, but there the purser handed me the pen right when security delivered it. the lady was clearly upset by that flagrant disregard of security, but he just shrugged ;-)18:20
whitequarkstrawberyargon: which plane18:20
whitequarkwpwrak: lol18:21
strawberyargonthomas cook airlines, ryianair maybe or monarch18:22
strawberyargonwhitequark, ^18:22
whitequarkwpwrak: which *plane*18:23
whitequarknot which *airline*18:23
wpwrakdunno ;-)18:23
whitequarker, s/wpwrak/strawberyargon.18:24
strawberyargonplane? idk18:24
strawberyargonnot bookedf18:24
whitequarkyou can look that up if you know the flight number18:24
whitequarkthey tell it to you before you book.18:24
strawberyargonoh trying to find the info18:24
strawberyargondid you guys know about talos? https://www.crowdsupply.com/raptor-computing-systems/talos-secure-workstation/updates/the-state-of-owner-controlled-computing-as-talos-winds-down?utm_source=Talos+Supporters&utm_campaign=19545976d2-talos_update_winds_down_2017_01_09&utm_medium=email&utm_term=0_451951d5fa-19545976d2-11239577319:45
DocScrutinizer05strawberyargon: not heard about talos, but the text there is pretty nice (first paragraph I read), and it explains excellently why Neo900 is needed20:25
strawberyargonaww i should have posted a link here sooner...20:25
strawberyargonknow anyone how might have pledged?20:26
strawberyargonjust wondering20:26
strawberyargonDocScrutinizer05, neo900, dont need proprietary stuff to record video from camera/encode? 21:14
strawberyargoni think so...21:15
strawberyargonjust wonding about alt to buying non-free action cam. with a diy computer + camera module/interface how hard it would be to get something... but then its gona be so bulky.... and by the time one was spent xxx on it such a project i guess one could have got a neo900 or at lest paid for part of one :)21:17
DocScrutinizer05strawberyargon: no, neo900 can record from camera using FOSS, I think21:17
strawberyargongreat :D21:17
strawberyargonhmm done much with solar DocScrutinizer05 ?21:18
DocScrutinizer05not really21:18
DocScrutinizer05then, there's not that much different solar things you could possibly do21:18
DocScrutinizer05unless I misunderstood "solar" (PV and heating)21:19
strawberyargonseeking advice on CIGS panels and where to get them. how risky might a experimental, development flexible pannel be? http://www.ebay.co.uk/itm/152364018330?_mwBanner=1 if you have any ideas that is21:21
strawberyargonsolar electric photovoltaic 21:21
strawberyargonDocScrutinizer05, hmm turn 150M roll into mini power station XD http://www.ebay.co.uk/itm/Generic-Solar-Panel-Top-Film-Roll-150M-Long-1-16M-Wide-0-6MM-Thick-/262774029933?hash=item3d2e8d7e6d21:22
strawberyargonthere was a company that have made a commercial portable container sized rollup solar power station21:29
strawberyargonforgot the name21:29
DocScrutinizer05my outdated knowledge about flexible PV: poor efficiency and terribly fragile21:33
DocScrutinizer05also that link sounds like... it's just the top film, not a real complete PV thing21:36
DocScrutinizer05the price tag suggests that too21:36
DocScrutinizer05I don't think you could get a 150+ square meters of PV cell for a ~500 bucks21:37
DocScrutinizer05or did you consider making CIGS yourself? :-o21:58
DocScrutinizer05on that Generic-Solar-Panel-Top-Film. Would probably be a very demanding project21:59
DocScrutinizer05anyway afaik the major source of problems/failures in flexible stuff are the electrodes which break or come loose22:02
DocScrutinizer05to be more precise: had been, several years ago22:12
strawberyargonCIGS are really good. they still work well in low light conditions unlike mono-crystalline 23:42
strawberyargonapparently there robust.23:42
DocScrutinizer05#define robust23:53
DocScrutinizer05sure, you could fire a whole peacemaker empty into one and odds are it works just like before with all those holes, but too often bended or with too narrow radious, and the electrode stuff came off or at least cracked, back when electrodes had significant layer thickness23:55
DocScrutinizer05btw all the same problem like e.g. with flexible OLED displays23:59
