| 00:25.10 | arossdotme | ok what about eoma-68 then? |
| 00:28.00 | 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. |
| 00:29.45 | 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. |
| 00:30.11 | arossdotme | I don't really want to make this mod as i'ld like to be able to pwer it from 12v still |
| 00:30.26 | arossdotme | and to not risk damaerging it |
| 00:30.54 | arossdotme | <PROTECTED> |
| 00:31.18 | arossdotme | but i would love to run it off a smaller batt pack |
| 00:31.33 | arossdotme | smaller and lighter! |
| 00:31.41 | arossdotme | the wieght is killing me |
| 00:32.30 | arossdotme | it works of a min of 6V. maybe theres a not to bad dc-dc that bosts the voltage upto 6V? |
| 00:32.40 | arossdotme | of=at |
| 00:33.14 | arossdotme | so i could use some old li-ion batts |
| 00:34.13 | arossdotme | this is for my diy camera rig |

| 09:27.37 | whitequark | wpwrak: http://solvespace.com/ |
| 09:27.45 | whitequark | appears to be a really, really nice parametric 3D CAD |
| 09:28.16 | 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 |
| 09:28.21 | whitequark | GPL3 |
| 09:28.35 | whitequark | and unlike freecad it actually works very well |
| 09:29.32 | whitequark | a nice part is that it can also solve constraints in 3D |
| 09:31.00 | viric | hm I remember this thing |
| 09:31.08 | viric | the video is quite impressive. |
| 09:31.43 | whitequark | i don't know how i haven't seen it earlier |
| 09:31.48 | whitequark | it looks absolutely amazing |
| 09:32.04 | viric | did you build it? |
| 09:32.13 | whitequark | i ran it under virtualbox :] |
| 09:32.27 | whitequark | after that i discovered that it's actually FOSS |
| 09:32.50 | viric | I remember as if I couln't build it for linu |
| 09:32.50 | viric | x |
| 09:33.06 | viric | maybe two years ago |
| 09:33.07 | whitequark | yes that should be fixed in the repo |
| 09:33.14 | whitequark | there's a recent forum thread about that |
| 09:33.22 | viric | ok |
| 09:40.47 | viric | ah we have it in nixpkgs |
| 09:47.20 | viric | whitequark: I tried to draw an object and I failed to constrain it. :) |
| 09:52.01 | whitequark | hmm? |
| 09:52.27 | viric | this is, I failed to draw it |
| 09:53.23 | viric | I needed some centering for symmetry, and I couldn't achieve it. |
| 09:54.11 | whitequark | hmm |
| 09:54.16 | whitequark | got a pic? |

| 11:54.19 | wpwrak | whitequark: looks interesting. i wonder if they support also variables, maybe even expressions, not just constants ? |
| 11:54.36 | viric | 90+45 works |
| 11:54.37 | viric | :) |
| 11:55.08 | viric | the UI is quite that of a videogame. :) |
| 11:56.49 | whitequark | wpwrak: no, not really |
| 11:56.51 | whitequark | but. |
| 11:56.56 | whitequark | the code is quite readable |
| 11:57.09 | whitequark | and unlike freecad with the horror that is opencascade, it's easily maintainable. |
| 11:57.30 | viric | opencascade are a few lines of code |
| 11:59.18 | whitequark | viric: can you open http://rghost.net/75qGtXsJF and say if it looks like https://imgur.com/648lAcq ? |
| 11:59.23 | whitequark | rendering on linux seems broken, somehow |
| 11:59.48 | 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 |
| 12:00.56 | wpwrak | and the really important thing is that opencascade actually works for "ideal" geometries :) unlike, say, cgal |
| 12:01.00 | whitequark | wpwrak: the sheer amount of it |
| 12:01.16 | wpwrak | (ideal = without taking into account numerical effects and such) |
| 12:01.23 | whitequark | i looked into writing something for opencascade and the cost/benefit ratio is close to infinity |
| 12:02.11 | viric | whitequark: quite like that |
| 12:02.20 | wpwrak | hihi :) |
| 12:03.29 | whitequark | viric: hah! this is on windows https://i.imgur.com/4sfwILI.png |
| 12:03.40 | viric | auhm |
| 12:03.45 | viric | nicer on windows |
| 12:04.00 | whitequark | they seem to have swapped the normals, or something |
| 12:04.02 | whitequark | weird bug |
| 12:04.08 | whitequark | also, no antialiasing on linux, ugh |
| 12:05.17 | whitequark | wpwrak: solvespace uses NURBS curves, as I understand |
| 12:05.26 | whitequark | which can represent a circle |
| 12:11.26 | 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. |
| 12:11.49 | wpwrak | opencascade is really good at doing such thing right |
| 12:12.03 | whitequark | ahh |
| 12:16.00 | whitequark | solvespace doesn't have this issue, because all unions or subtractions must be constructed on a workplane on top of another solid |
| 12:16.21 | whitequark | so if something is coincident, it already knows it perfectly |
