2015-03-06 00:25 <arossdotme> ok what about eoma-68 then?
2015-03-06 00:28 <arossdotme> off topic: i have a 4.3 inch compersite input lcd thats pwoered off 12v. it's a recent one that has a ultr compacte pcb but it does have points to solder wires too like a 3.3v one to power it. i have checked the power chicp and it outputs 3.3~V. anyway so i tried powering it via 3.3V but it switches on and off. the picture is displayed and litgh up for less then 1sec and then off and on, it repeats.
2015-03-06 00:29 <arossdotme> theres a rpi forum thread about these mods but theres no anwser for this pcb. on prev mods they remove the pwr IC and someone removed a inductor and i think a cap. looking at the cirect diagram it looks like i also want to remove/cut some restors as well.
2015-03-06 00:30 <arossdotme> I don't really want to make this mod as i'ld like to be able to pwer it from 12v still
2015-03-06 00:30 <arossdotme> and to not risk damaerging it
2015-03-06 00:30 <arossdotme>  / cockup
2015-03-06 00:31 <arossdotme> but i would love to run it off a smaller batt pack
2015-03-06 00:31 <arossdotme> smaller and lighter!
2015-03-06 00:31 <arossdotme> the wieght is killing me
2015-03-06 00:32 <arossdotme> it works of a min of 6V. maybe theres a not to bad dc-dc that bosts the voltage upto 6V?
2015-03-06 00:32 <arossdotme> of=at
2015-03-06 00:33 <arossdotme> so i could use some old  li-ion batts
2015-03-06 00:34 <arossdotme> this is for my diy camera rig

2015-03-06 09:27 <whitequark> wpwrak: http://solvespace.com/
2015-03-06 09:27 <whitequark> appears to be a really, really nice parametric 3D CAD
2015-03-06 09:28 <whitequark> they only ship windows binaries for some obscure reason, but you can build it yourself from https://github.com/rlutz/solvespace. autoconf as usual
2015-03-06 09:28 <whitequark> GPL3
2015-03-06 09:28 <whitequark> and unlike freecad it actually works very well
2015-03-06 09:29 <whitequark> a nice part is that it can also solve constraints in 3D
2015-03-06 09:31 <viric> hm I remember this thing
2015-03-06 09:31 <viric> the video is quite impressive.
2015-03-06 09:31 <whitequark> i don't know how i haven't seen it earlier
2015-03-06 09:31 <whitequark> it looks absolutely amazing
2015-03-06 09:32 <viric> did you build it?
2015-03-06 09:32 <whitequark> i ran it under virtualbox :]
2015-03-06 09:32 <whitequark> after that i discovered that it's actually FOSS
2015-03-06 09:32 <viric> I remember as if I couln't build it for linu
2015-03-06 09:32 <viric> x
2015-03-06 09:33 <viric> maybe two years ago
2015-03-06 09:33 <whitequark> yes that should be fixed in the repo
2015-03-06 09:33 <whitequark> there's a recent forum thread about that
2015-03-06 09:33 <viric> ok
2015-03-06 09:40 <viric> ah we have it in nixpkgs

2015-03-06 09:47 <viric> whitequark: I tried to draw an object and I failed to constrain it. :)
2015-03-06 09:52 <whitequark> hmm?
2015-03-06 09:52 <viric> this is, I failed to draw it
2015-03-06 09:53 <viric> I needed some centering for symmetry, and I couldn't achieve it.
2015-03-06 09:54 <whitequark> hmm
2015-03-06 09:54 <whitequark> got a pic?

2015-03-06 11:54 <wpwrak> whitequark: looks interesting. i wonder if they support also variables, maybe even expressions, not just constants ?
2015-03-06 11:54 <viric> 90+45 works
2015-03-06 11:54 <viric> :)
2015-03-06 11:55 <viric> the UI is quite that of a videogame. :)
2015-03-06 11:56 <whitequark> wpwrak: no, not really
2015-03-06 11:56 <whitequark> but.
2015-03-06 11:56 <whitequark> the code is quite readable
2015-03-06 11:57 <whitequark> and unlike freecad with the horror that is opencascade, it's easily maintainable.
2015-03-06 11:57 <viric> opencascade are a few lines of code
2015-03-06 11:59 <whitequark> viric: can you open http://rghost.net/75qGtXsJF and say if it looks like https://imgur.com/648lAcq ?
2015-03-06 11:59 <whitequark> rendering on linux seems broken, somehow
2015-03-06 11:59 <wpwrak> what's horrible about opencascade ? at least on freecad the primitives i access in scripts are at an appropriate level of abstraction, underneath it all is opencascade
2015-03-06 12:00 <wpwrak> and the really important thing is that opencascade actually works for "ideal" geometries :) unlike, say, cgal
2015-03-06 12:01 <whitequark> wpwrak: the sheer amount of it
2015-03-06 12:01 <wpwrak> (ideal = without taking into account numerical effects and such)
2015-03-06 12:01 <whitequark> i looked into writing something for opencascade and the cost/benefit ratio is close to infinity
2015-03-06 12:02 <viric> whitequark: quite like that
2015-03-06 12:02 <wpwrak> hihi :)
2015-03-06 12:03 <whitequark> viric: hah! this is on windows https://i.imgur.com/4sfwILI.png
2015-03-06 12:03 <viric> auhm
2015-03-06 12:03 <viric> nicer on windows
2015-03-06 12:03 <whitequark> they seem to have swapped the normals, or something
2015-03-06 12:04 <whitequark> weird bug
2015-03-06 12:04 <whitequark> also, no antialiasing on linux, ugh
2015-03-06 12:05 <whitequark> wpwrak: solvespace uses NURBS curves, as I understand
2015-03-06 12:05 <whitequark> which can represent a circle
2015-03-06 12:11 <wpwrak> whitequark: i mean things like operations on volumes producing sensible results. e.g., subtracting things with conincident surfaces will not leave super-thin layers (or worse) behind. or merging solids with coincident surfaces won't have some tiny empty space between them.
2015-03-06 12:11 <wpwrak> opencascade is really good at doing such thing right
2015-03-06 12:12 <whitequark> ahh
2015-03-06 12:16 <whitequark> solvespace doesn't have this issue, because all unions or subtractions must be constructed on a workplane on top of another solid
2015-03-06 12:16 <whitequark> so if something is coincident, it already knows it perfectly
