Just letting people know. I dont quite have the time to learn Wiki and wiki code to organize the wikipedia as of yet. I am currently documenting my projects on Hackaday since there seems to be pretty knowledgable individuals on that site. Plus its really… really nice for project organization. Logs, parts, and all that. Its quite convenient at least for me on the go to publish my ideas and individual progress… letting everyon
02:47
Rebelj12a
know.

Rebelj12a
Also all data and info found out when experimenting and making these projects work, im documenting and putting in the Open Source “idea cloud” of the apertus Wiki
02:49

Current project is a small video light and barn doors portable one…. Either or may be powered by arduino I dont know depends on which is more interesting. I have one Arduino UNO and thats all XD so gotta pick and choose. The concepts are sound though.
02:50
Rebelj12a
Also reason im doing these is I found out… well… apparantly I have 4 plus some surplus scanners downstairs I didnt realize I still had haha.
03:03
Rebelj12a
Also if anyone wants to help. Hey feel free to message me. I could use some help on some of the specifics.

troy_s
Rebelj12a: Make progress with your i1 yet?
04:18
troy_s
Rebelj12a: i'd highly (hugely) rec dispcalgui if you haven't gotten it yet.
04:19
Rebelj12a
hmm
04:19
Rebelj12a
For?
04:19
troy_s
Uh profiling.
04:19
Rebelj12a
Oh not the built in ical profiling?
04:19
troy_s
(there are two sides to display work - calibration and characterization (aka profiling))
04:19
Rebelj12a
er sorry i1display
04:19
troy_s
The software that ships with the devices generally sucks.
04:20
troy_s
Not nearly enough control.
04:20
Rebelj12a
Fair enough, too true in most cases
04:20
troy_s
If you see a big green button that says "DO MAGIC" generally don't trust it.
04:20
troy_s
There's a little theory in behind characterization / profilng that would serve anyone interested in digital imaging extremely well to learn.
04:20
troy_s
Highly advised.
04:20
Rebelj12a
Oh CRAP that site led me to another site with an android app link for using the i1display for color metering.
04:21
Rebelj12a
sweet
04:21
troy_s
The good news is that dispcalgui is an advanced interface, but likely 'entry level' enough to serve an enthusiast.
04:21
troy_s
look for dispcalgui
04:21
Rebelj12a
Ill be honest… graphic artists, photographers, other such people in this area… They dont even know what color profiling is.
04:21
Rebelj12a
Me just knowing and having… puts me that far ahead XD
04:21
troy_s
Argyll now has an Android app. That's Graeme's way of earning some money off of his (colossal) effort.
04:21
troy_s
You only need dispcalgui
04:21
troy_s
It ships with a recent Argyll.
04:21
troy_s
A _really_ amazing product.
04:22
troy_s
Includes Resolve profiling now too.
04:22
troy_s
Florian is a rock star.
04:22
Rebelj12a
niiice
04:22
troy_s
Really is.
04:22
troy_s
If you snag it, I can sleepwalk you through the basics.
04:23
troy_s
It's prudent to characterize / profile your display about once per month or so.
04:23
Rebelj12a
Yeah I do that
04:23
troy_s
Drift happens.
04:23
troy_s
But the real issue is that the default software doesn't really tell you anything as to what is going on.
04:23
troy_s
Whereas Graemes is all text files and verbose output.
04:23
troy_s
You can _really_ see what is happening.
04:23
troy_s
(In terms of measured XYZ values etc.)
04:24
Rebelj12a
Just gotta figure out how to set up my broadcast monitor to my Macbook Pro. Marshall VLCD50MD - bah I dont want to shell out for the thunderbolt to SDI D:
04:24
troy_s
Your Marshall is a 7 inch?
04:24
Rebelj12a
uh yes
04:24
Rebelj12a
I believe
04:24
troy_s
What is your broadcast?
04:24
troy_s
Or is that your broadcast?
04:24
Rebelj12a
Yeah it is
04:25
troy_s
So for 709 that thing should be effectively set to 1886.
04:25
troy_s
(BT.1886)
04:25
troy_s
In terms of transfer curve.
04:25
Rebelj12a
yeah
04:25
troy_s
Whereas your Macbook should be sRGB (which is around 2.4)
04:25
troy_s
"Correct" sRGB viewing and "correct" 709 viewing are almost identical.
04:26
troy_s
sRGB has a two part transfer that averages out to close to 2.4ish. 709 is encoded at 1.9closeish (again a two parter) and to be viewed on BT.1886 which is 2.4 gamma.
04:26
Rebelj12a
Yeah just cant get the macbook to recognize it
04:26
troy_s
???
04:26
troy_s
The display?
04:26
Rebelj12a
Yeah
04:26
Rebelj12a
Only hookup is hdmi
04:27
troy_s
Via HDMI?
04:27
troy_s
And the Macbook is shitting the bed?
04:27
Rebelj12a
yep
04:27
troy_s
Good god.
04:27
troy_s
You'd think that if you spent 2000$ on a lump of metal that it _might_ work.
04:27
Rebelj12a
You would think.
04:27
troy_s
Perhaps we ask too much.
04:27
troy_s
Perhaps we can only get working HDMI on a 10000$ item.
04:28
Rebelj12a
Prooobably since we arent in Apples target market.
04:28
troy_s
They should just write that on the box.
04:28
troy_s
"Comes with an HDMI port. To software unlock, please purchase the 12014$ App.)
04:28
Rebelj12a
bah
04:28
troy_s
(Despite the fact that 30$ DVD players from China ship with working HDMI.
04:28
Rebelj12a
Im sure theres a way. but all forum posts and such post it wont work without an adapter.
04:29
troy_s
Ridiculous.
04:29
Rebelj12a
No it does work, on regular screens
04:29
troy_s
Your Marhsall is only 1080 at the _most_
04:30
troy_s
Anyways... go snag dispcalgui
04:30
troy_s
I generally have been leaning towards folks _not_ calibrating their displays and merely characterizing them.
04:32
Rebelj12a
Yeah I grabbed it but I gotta go for a bit. In the middle of a few things.
04:32
troy_s
Largely due to the fact that A) graphics cards can poop the sheets and drop the 1D transfer curve table thereby making the profile moot and B) is faster / easier to accomplish.

Does apertus use cern open hardware license v1.1 or v 1.2 ? The difference being http://www.ohwr.org/projects/cernohl/wiki/FAQ#CERN-OHL-v12
08:46
comradekingu
There is even the TAPR open hardware license http://www.tapr.org/TAPR_Open_Hardware_License_v1.0.txt
08:46
comradekingu
I think there is a distinction between open hardware and open source hardware, but ive forgotten what is what
08:51
comradekingu
TAPR difference "... those who benefit from an OHL design may not bring lawsuits claiming that design infringes their patents or other intellectual property."
08:52
comradekingu
i think bringing patents into the picture is a bonus, but that open hardware makes more sense for apertus than free hardware
08:53
philippej
this has been discussed a lot already :-)
08:53
comradekingu
Since "clone merely for profit" is a term
08:53
comradekingu
philippej: what was the conclusion?
08:55
philippej
the most recent summary is here I'd say : https://www.apertus.org/openness-explained-2014
08:55
comradekingu
ok
08:55
comradekingu
For documentation there is a link to creative commons, but that isnt actually a license. its always BY-CC-SA or some variant thereof
08:55
philippej
don't hesitate to propose better wording
08:56
comradekingu
as we are gathered around the vaginal table, this very serious assembly may now start
08:56
philippej
with the little caveats that we "voted" this statement :-)
08:56
comradekingu
i was going for the, "someone told me, i blame them" quickfix
08:57
comradekingu
i see what you mean about the wording
08:58
philippej
when we decided that, as far as I remember, every member worked on a shared document to try to best write our intent, than we voted for it
08:58
philippej
se6astian|away would give more insight
09:01
comradekingu
“As open as possible, as closed as necessary” sounds somwhat redundant after the comma
09:02
comradekingu
"have recently met up in a virtual boardroom" this is so cringeworthy it just has to be left in
09:03
comradekingu
"We have banned all proprietary interfaces and parts without open documentation from being utilised in the camera core"
09:03
comradekingu
"The Axiom base system is defined by the following logical and physical parts: image sensor front-end, processing board, external interface board, power management"
09:03
philippej
I guess it's better to consider this doc history of the project and keep it as such
09:04
comradekingu
then from the current opensource page: "For some interfaces we have to use proprietary protocols which we can also not disclose in the code (eg. “industry standard” but proprietary battery communication protocols)."
09:05
comradekingu
is base system somehow different from camera core?
09:05
philippej
separation of core and additional interfaces
09:05
philippej
for example shields on beta
09:06
philippej
be warned we can nitpick over this for years without bringing anything useful to the table :-)
09:07
comradekingu
to the virtual boardroom! with the vaginal table, one community enters, nobody leaves
09:07
philippej
:-)
09:07
comradekingu
well it said cern open hardware license 1.2 so ill stick with that
09:10
comradekingu
i like the requirement of notifying of modifications of v1.1, i wonder when it kicks in though
09:11
comradekingu
documentation provided CC, links to https://creativecommons.org/licenses/by-sa/3.0/
09:28
comradekingu
i think https://www.apertus.org/node/348/revisions/2903/view looks presentable now, thoughts?

Hi guys, so do you actually have the drafts for the bayonet part of nikon-f lens mount or do you still need them?

Suppose a sufficiently advanced shop without relevant experience was ready to help me. I would need to give them drafts right? Blueprints?
