<arossdotme> ok what about eoma-68 then?
<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.
<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.
<arossdotme> I don't really want to make this mod as i'ld like to be able to pwer it from 12v still
<arossdotme> and to not risk damaerging it
<arossdotme> / cockup
<arossdotme> but i would love to run it off a smaller batt pack
<arossdotme> smaller and lighter!
<arossdotme> the wieght is killing me
<arossdotme> it works of a min of 6V. maybe theres a not to bad dc-dc that bosts the voltage upto 6V?
<arossdotme> of=at
<arossdotme> so i could use some old li-ion batts
<arossdotme> this is for my diy camera rig

<whitequark> wpwrak: http://solvespace.com/
<whitequark> appears to be a really, really nice parametric 3D CAD
<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
<whitequark> GPL3
<whitequark> and unlike freecad it actually works very well
<whitequark> a nice part is that it can also solve constraints in 3D
<viric> hm I remember this thing
<viric> the video is quite impressive.
<whitequark> i don't know how i haven't seen it earlier
<whitequark> it looks absolutely amazing
<viric> did you build it?
<whitequark> i ran it under virtualbox :]
<whitequark> after that i discovered that it's actually FOSS
<viric> I remember as if I couln't build it for linu
<viric> x
<viric> maybe two years ago
<whitequark> yes that should be fixed in the repo
<whitequark> there's a recent forum thread about that
<viric> ok
<viric> ah we have it in nixpkgs

<viric> whitequark: I tried to draw an object and I failed to constrain it. :)
<whitequark> hmm?
<viric> this is, I failed to draw it
<viric> I needed some centering for symmetry, and I couldn't achieve it.
<whitequark> hmm
<whitequark> got a pic?

<wpwrak> whitequark: looks interesting. i wonder if they support also variables, maybe even expressions, not just constants ?
<viric> 90+45 works
<viric> :)
<viric> the UI is quite that of a videogame. :)
<whitequark> wpwrak: no, not really
<whitequark> but.
<whitequark> the code is quite readable
<whitequark> and unlike freecad with the horror that is opencascade, it's easily maintainable.
<viric> opencascade are a few lines of code
<whitequark> viric: can you open http://rghost.net/75qGtXsJF and say if it looks like https://imgur.com/648lAcq ?
<whitequark> rendering on linux seems broken, somehow
<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
<wpwrak> and the really important thing is that opencascade actually works for "ideal" geometries :) unlike, say, cgal
<whitequark> wpwrak: the sheer amount of it
<wpwrak> (ideal = without taking into account numerical effects and such)
<whitequark> i looked into writing something for opencascade and the cost/benefit ratio is close to infinity
<viric> whitequark: quite like that
<wpwrak> hihi :)
<whitequark> viric: hah! this is on windows https://i.imgur.com/4sfwILI.png
<viric> auhm
<viric> nicer on windows
<whitequark> they seem to have swapped the normals, or something
<whitequark> weird bug
<whitequark> also, no antialiasing on linux, ugh
<whitequark> wpwrak: solvespace uses NURBS curves, as I understand
<whitequark> which can represent a circle
<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.
<wpwrak> opencascade is really good at doing such thing right
<whitequark> ahh
<whitequark> solvespace doesn't have this issue, because all unions or subtractions must be constructed on a workplane on top of another solid
<whitequark> so if something is coincident, it already knows it perfectly
