morning everyone!

how are you?

I'm fine, thanks for asking, and you?

a bit hindered by the "omg I am back where should I start my work again now" feeling still ;)

the led matrix arrived I read

did you get to populate the PCB yet?

great!

sure

I guess the path to get that done is pack the current state of the design into a file that is easiest to read (PDF maybe) and then send it off to the axiom-dev mailing list together with a description of what exactly needs being checked/verified?

I was thinking of moving the SSD drive bays from the front/right to the back/left side as having to remove the handle to change disks could be seen as rather cumbersome

well, the layout is available as .tar.xz and .zip of pdfs already

and I'm fine to send it to oshpark as is, although I'd appreciate some feedback (got none yet)

URL please ;)

the zip and tar.xz both contain a set of pdfs for the layers, masks and silk screen

no idea at the moment

there was a run on the 22nd of july

everything, from part footprints over schematic connections to possible high frequency problems in the layout

so we should be somewhat flexible to add some stuff as patch

(we need the 3.0V regulator though)

this would be what I send to the entire team

it seems the next 4layer is planned for Aug 15th

the last one was Aug 5th, according to twitter

well, it takes about two weeks in the fab (IIRC) and another 1-2 to get here (JFYI)

email sent

here a still: http://vserver.13thfloor.at/Stuff/AXIOM/2013-08-13%2014.22.40.jpg

now when the 1.8" ssds go into the enclosure: a) how to get them back out and b) how to close the "door" when they are inside the enclosure...

so we already know, we want SATA and 1.8" SSD(s) in the final camera?

unless there are reasons for not going that way that I dont know of yet

(which might include a SATA disk/raid of course)

but I'm fine with having SATA 1.8" fixed as well, are there any plans to test that (i.e. some kind of prototype?)

the Axiom concept is just vapour ware so far ;)

or let me rephrase that

goals: 1. finish prototype 2. shoot some sample footage 3. present footage and Axiom concept in crowdfunding campaign 4. raise the money and dance or cry and move on

of course it cant hurt to know the next development steps, but we shouldnt get ourselves tangled up in the details already

no problem with planning a stage after that which includes e.g. on-board sata

(and it will require a test system with high speed serial already available, like the one I'd consider the next step :)

well do you have the concept image in the last version in front of you?

subject: Rethinking the Axiom concept - please particiapte

yes extension04.jpg

okay, so we are on the same page then, good!

and I'm also sure that the Axiom HD should be designed to do 4K via those serial ports

we could just add an SFP+ port to the HD variant to enable higher bandwidth transfers?

should visualize 3 BNC connectors ;)

like this: http://www.lafcpug.org/images_review_pana_hpg20/07_ag_hpg_20_recorder_brockett.jpg

one could be 3g-sdi cleanfeed for recording, the other one with OSD overlays, the last one I don't know yet :)

okay, I don't think that we should designate the connectors (not even sure that 3xBNC is the best idea, but I'm fine with BNC in general :)

so we could transport up to 2.97 Gbit/s on each port (assuming 3G-SDI)

you mean we go the route the reassign the protocol/standard on each connector via the FPGA on the fly?

I think that is part of the desired flexibility, no?

we just need to find a way how to display to users what the connector is doing atm

could be on the OSD screen (wherever that is) or via some (o)led

I don't think that is something which will change during recording

status led is a nice idea

will do that now ;)

as I said, I don't think that is something you change often, IMHO it makes more sense to label the ports clearly

and then have a (G)UI to select SD-A is video raw, SD-B is video + overlay, SD-C is data for recorder/SATA for example

or on a different setup, SD-A is view finder, SD-B and SD-C is 4k recorder (for example)

very simple, green is cleanfeed, orange is OSD

so you still need a legend what color is what

but yeah, an RGB led besides each connector won't hurt (just draw additional power but that can be turned off:)

it will get confusing if you label a port as HD or clean or whatever basically limits the data being transferred

note that SD/HD/3G-SDI are all backwards compatible
