Bertl
morning everyone!
12:29
se6astian
hello!
12:31
se6astian
about the prototype enclosure
12:32
se6astian
I was thinking of a general aluminum project box that can hold the dimensions of a zedboard
12:32
se6astian
like this: http://www.conrad.at/ce/de/product/534483/Universal-Gehaeuse-Aluminium-Schwarz-275-x-175-x-65-Hammond-Electronics-1550JBK-1-St/0203042
12:33
se6astian
and then we mill out the area from the top cover that we need to attach he lens mount part
12:33
se6astian
and the Zedboard we attach with glued spacers from the inside
12:34
se6astian
what do you think?

se6astian
ok afk fo a bit
13:30
se6astian
back
13:43
Bertl
hmm, doesn't really look appealing to me
13:44
Bertl
besides, do we get that in a size which fits the zedboard but doesn't look like a shoebox?
13:45
Bertl
I'd more go for a clear acrylic case with cutouts and ventilation holes (lasercutter)
13:46
Bertl
where you can see the parts inside
13:56
se6astian
the picture is wrong
13:56
se6astian
its actually black
13:56
se6astian
so it should look a bit more classy ;)
13:56
se6astian
transparent is also fine
13:57
se6astian
and plastic is easier to cut/mill/laster as well
13:57
se6astian
it should just be strong enough to carry not only the lens mount but a 1kg lens as well
14:03
Bertl
well, probably needs some extra stabilization on the lensmount then
14:03
Bertl
i.e. something which tightly holds the lens mount
14:03
Bertl

what about just a steel L bracket (http://www.tuin.co.uk/images/D/garden-l-bracket.jpg) that connects lens mount and bottom tripod mount of the box?
14:48
Bertl
sounds good, but how would that attach to the lens mount?
14:50
Bertl
we can screw the zedboard to the base of whatever case we use, with 4 spacers and screws. the adapter is only connected via two spacers and screws and the FMC connector
14:50
Bertl
so there we have to be careful not to bend or twist anything
14:51
Bertl
the lens mount is connected via 4 tiny screws to the adapter, which imho is the really critical part
14:54
Bertl
maybe we could design some kind of lens mount holder which matches the round front and prevents any tilt from the lens weight
14:59
se6astian
the l bracket could attach to the lens mount with the 4 screws around the opening on the lensmount back
14:59
se6astian
we would need to cut a matching hole into the l bracket for the image sensor though
15:00
Bertl
that won't work
15:00
Bertl
there are components around the sensor, and the space is very tight
15:01
Bertl
i.e. I doubt you can fit any bracket there without damage
15:01
se6astian
hmm maybe from the other side, eg holding the lens mount from "outside" ?
15:01
se6astian
along the tube?
15:02
se6astian
ok, gotta leave my university office
15:02
se6astian
bye!

Bertl
he was here around 17:30, didn't say anything either
17:32
Bertl
so I guess it is still a problem with his IRC client
17:34
NeillA
Hi
17:36
Bertl
hey NeillA! wecome to the channel!
17:38
NeillA
Can't stay for long, i was just trying to get IRC set up on my tablet.
17:38
Bertl
seems to work!
17:38
NeillA
Yep, good start then
17:40
se6astian
hello, welcome!
17:41
NeillA
Hello
17:41
se6astian
good to have you here, IRC felt a bit oldschool for me at first after not using it for almost 10 years :)
17:41
se6astian
but I got quite used to it again, works nicely now :)
17:41
NeillA
Yeah, can't remember when i last used it.
17:43
Bertl
two hours ago :)
17:44
NeillA
Yeah, memory like a goldfish :-)
17:46
se6astian
;)
17:46
se6astian
So Neill, you got my mail about ou FPGA efforts to build an emulated sensor
17:46
se6astian
do you think you could help with that?
17:48
NeillA
Yeah, have you got a model of the sensor from cmosis?
17:49
jucar2
joined the channel
17:50
se6astian
yes, we have one, but it would not really be required for the emulation
17:50
Bertl
hmm, I sense a misunderstanding
17:50
Bertl
NeillA: yes, we got the VHDL code from Cmosis
17:50
Bertl
(which contains a simulation model)
17:51
NeillA
Ok, thats good
17:51
Bertl
se6astian can send it to you, I guess?
17:52
NeillA
That might be good
17:52
jucar1

17:53
se6astian
yes will do it right away
17:53
NeillA
Is it the generic model they have for the cmv4000?
17:53
Bertl
maybe, I'd say likely, but not in the codebase we got for the CMV12k
17:54
se6astian
sent
17:54
NeillA
Ok, well i'll have a look.
17:55
se6astian
the full datasheet is also on our github account: https://github.com/apertus-open-source-cinema/alpha-hardware/blob/master/Datasheets/datasheet_CMV12000%20v8.pdf
17:56
NeillA
Ok thanks
17:57
Bertl
and if you find the time, please review the adapter board ... feedback is much appreciated
17:58
se6astian
here is the direct link to the pdf

and here is the direct link to the adapter: https://github.com/apertus-open-source-cinema/alpha-hardware/raw/master/SFE-PCB/cmv12k-adapter-v1.0.brd
18:01
NeillA
So do you know what the current status of the emulated sensor is?
18:02
Bertl
I think dmj_nova got his zedboard up and running (with TFTP boot) and was working on 300MHz clock last time he was around
18:02
Bertl
so I wouldn't expect too much progress (yet)
18:03
NeillA
Ok its a start anyway
18:03
Bertl
definitely!
18:04
NeillA
I'll have to dig out my zedboard
18:07
NeillA
I've got to go now, chat again later
