So I had questions...

and how the person who has designed the board can debug and make the board work without the rest of the system/

this basically means that you can get a 'system' for a few hundred bucks

but to answer the original question, who pays for the tooling, parts, assembly

so, either the developer because he wants to do some on-time proprietary module

or a larger group of interested people which consider this module worth sponsoring or developing

I see..

we do it in our spare time and we often do it on our money

(except for donations and such)

I'd say, you'd have a pretty good module with some kind of SDI interface if you can pull it off

It doesn't make sense to do anything on the actual design since it is just design for development, it would have to be redone to fit the proposed final design

I think there will be no final version, but I guess you mean beta and you are referring to gamma as the final version

and yes, it would have to be redone, and no, IMHO it does make a lot of sense to make it fit for the beta as well

for example to get proper software support, integration, testing, etc

well, kind of, there has to be a core team, and there will be many, many sattelite projects

So, the more I think about it, the more it is like a very individual kind of thing and it ties back with my email I wrote yesterday. In a world where I would not have my own stuff, getting involved would be awesome, but now, since I have my own stuff, the investment of time is a bit pointless...

true...

let's say you have the blueprint for a perfect SDI module

let's further assume, that you can build a prototype of said module in the next few months for Beta

I'm pretty sure in that case we will find somebody to donate you the Beta hardware for testing that module

I understand... I mean, the idea to conceive the Schematic and PCB for me is no big deal, I have designed that thing over and over...

care to show me a schematic?

the Beta will be able to do that

heck, we have been shooting for some time now with the shoebox called Alpha :)

I am sorry to say, but there is no way this setup would work more then a Day on Set...

Listen, I don't to belittle what you have, I am just saying that it would not be very pratical on set. And I feel the original intent of Oscar has shift towards a more common usage of the camera instead of being targetted solely to be a Film camera to shoot movies...

but right now, it is like you said a development platform for anybody to use and to a certain degree it might be a better idea to bring more people in...

but if all you want is 'just' a camera, it is probably simpler to buy a red or whatever is cheapest at the moment

I wish I would have that kind of money... but tell me, what motivated Oscar to want a camera?

yes but I think he can afford 'a camera', what he wants is a camera with certain features

s/features/qualities/

great! so just do it :)

So, this is what I am doing now...

It is a bit tricky in the hardware world...

TO do what?

and no problem with being straight, I appreciate it

(there is a wiki page about the apertus philosophy)

well, that would actually have worked :)

You know, in terms of having all the info available it is priceless, to be able to have access to schematic and stuff even if it is just for a piece of design....

okay... that's weird...

really, they wanted you to pay them to design something?

this is nuts...

listen, what I am thinking is that what I could do in the short terms is come up with a schematic of the thing and I could even lay it out for Beta or Gamma... and then if somebody wants to make it then it is done...

https://apertus.org/opensource

well, we have little money too and we manage so far

I know... I am juggling with a lot of ideas right now and try to be very effective about it... Trying to pull some favors get free sample... so on and so forth!

why is that?

then, the design has to match the camera (be it beta or gamma) in many aspects

(power management, form factor, interfaces, etc)

the Display Port core, is a core you need to pay but not the SDI

software interfaces matter as well, after all it has to 'work' with other designs, modules, etc

so to be clear here, it is way simpler just to whip up something for yourself

Do you have a control bus like I2c or something/

there is no fixed design for the beta yet, on the alpha we use two image pipelines

https://wiki.apertus.org/index.php?title=Axiom_Alpha_Software#Image_Pipeline

this includes I2C devices, like the temperature sensors, the HDMI chip and the cmv12k

the image data itself is currently dumped into memory with triple (actually quadrupple) buffering

all LUTs are 1D here

the color correction in the alpha is done with a 4x4 + 4 matrix

OKay you are running Unbuntu on the Zynq... Sweet...

actually we are running a very simple busybox setup on the alpha, with a raspian chroot

it helped testing a lot as you can simply ssh into the camera and change registers

Make sense... I naturally usually stay very far from Operating System...

But, I have a phoby of them! ;)

Duh!!! C'mon, I was talking about the camera or small electronic device...

well, the advantage here is that we do not have to 'implement' it, because it is already available :)

That's my point!

Again, this is just me making my life difficult... lol

I have to learn the hard way!

But, again, maybe it is a missconception and also because I am probably a bit scared of the whole thing!

speaking of, we had a few potential partners which got really scared when they heard that we are doing 'open source' :)

Well, partners being scared means either not understanding the challenges or not seeing a profit!

I will...

Sure there are some thinking to be done here... for sure

BTW, are you not supposed to be sleeping right now?

It is nice of you to say!

:)

yes, BUT

it's morning when I get up, and it's evening when I go to bed :)

okay 11:00 AM instead of noon

what do you do to make a living?

cool, I used to do that too. I ran out of job...

Cheers!

off to bed now ... have a good one everyone!

good morning

good night everyone
