00:25 <arossdotme> ok what about eoma-68 then?

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.

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.

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

00:30 <arossdotme> and to not risk damaerging it

00:30 <arossdotme> / cockup

00:31 <arossdotme> but i would love to run it off a smaller batt pack

00:31 <arossdotme> smaller and lighter!

00:31 <arossdotme> the wieght is killing me

00:32 <arossdotme> it works of a min of 6V. maybe theres a not to bad dc-dc that bosts the voltage upto 6V?

00:32 <arossdotme> of=at

00:33 <arossdotme> so i could use some old li-ion batts

00:34 <arossdotme> this is for my diy camera rig

09:27 <whitequark> wpwrak: http://solvespace.com/

09:27 <whitequark> appears to be a really, really nice parametric 3D CAD

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

09:28 <whitequark> GPL3

09:28 <whitequark> and unlike freecad it actually works very well

09:29 <whitequark> a nice part is that it can also solve constraints in 3D

09:31 <viric> hm I remember this thing

09:31 <viric> the video is quite impressive.

09:31 <whitequark> i don't know how i haven't seen it earlier

09:31 <whitequark> it looks absolutely amazing

09:32 <viric> did you build it?

09:32 <whitequark> i ran it under virtualbox :]

09:32 <whitequark> after that i discovered that it's actually FOSS

09:32 <viric> I remember as if I couln't build it for linu

09:32 <viric> x

09:33 <viric> maybe two years ago

09:33 <whitequark> yes that should be fixed in the repo

09:33 <whitequark> there's a recent forum thread about that

09:33 <viric> ok

09:40 <viric> ah we have it in nixpkgs

09:47 <viric> whitequark: I tried to draw an object and I failed to constrain it. :)

09:52 <whitequark> hmm?

09:52 <viric> this is, I failed to draw it

09:53 <viric> I needed some centering for symmetry, and I couldn't achieve it.

09:54 <whitequark> hmm

09:54 <whitequark> got a pic?

11:54 <wpwrak> whitequark: looks interesting. i wonder if they support also variables, maybe even expressions, not just constants ?

11:54 <viric> 90+45 works

11:54 <viric> :)

11:55 <viric> the UI is quite that of a videogame. :)

11:56 <whitequark> wpwrak: no, not really

11:56 <whitequark> but.

11:56 <whitequark> the code is quite readable

11:57 <whitequark> and unlike freecad with the horror that is opencascade, it's easily maintainable.

11:57 <viric> opencascade are a few lines of code

11:59 <whitequark> viric: can you open http://rghost.net/75qGtXsJF and say if it looks like https://imgur.com/648lAcq ?

11:59 <whitequark> rendering on linux seems broken, somehow

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

12:00 <wpwrak> and the really important thing is that opencascade actually works for "ideal" geometries :) unlike, say, cgal

12:01 <whitequark> wpwrak: the sheer amount of it

12:01 <wpwrak> (ideal = without taking into account numerical effects and such)

12:01 <whitequark> i looked into writing something for opencascade and the cost/benefit ratio is close to infinity

12:02 <viric> whitequark: quite like that

12:02 <wpwrak> hihi :)

12:03 <whitequark> viric: hah! this is on windows https://i.imgur.com/4sfwILI.png

12:03 <viric> auhm

12:03 <viric> nicer on windows

12:03 <whitequark> they seem to have swapped the normals, or something

12:04 <whitequark> weird bug

12:04 <whitequark> also, no antialiasing on linux, ugh

12:05 <whitequark> wpwrak: solvespace uses NURBS curves, as I understand

12:05 <whitequark> which can represent a circle

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.

12:11 <wpwrak> opencascade is really good at doing such thing right

12:12 <whitequark> ahh

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

12:16 <whitequark> so if something is coincident, it already knows it perfectly
