Hi Bertl. How are you?
02:23
Bertl
fine, thanks for asking! and you?
02:24
Sasha_C
I'm well too. It's a miserable rainy day in Sydney today, so I'm lucky to be inside (working in my creative studio today...)
02:26

Awesome news! :D

Bertl: what's your current distro?
05:16
Bertl
where?
05:17
dmj_nova
on your axiom dev box
05:17
Bertl
mageia
05:18
dmj_nova
about to upgrade to saucy, hopefully I won't break the xilinx tools :P
05:20
Bertl
well, if it manages to break them, you can always use the older libraries for the tools, no?
05:20
dmj_nova
well, yes. Just hoping no frankensteining will be needed
05:21
dmj_nova
figured I'd see what you were using in case there was relevant information to be had
05:22
dmj_nova
For Novacut it's kinda important to be keeping current
05:22
Bertl
somebody reported that most recent ubuntu did not work with the tools, but I'm not sure that was really distro related
05:24
dmj_nova
when was that?
05:25
Bertl
not too long ago
05:26
dmj_nova
what was wrong?
05:26
Bertl
something about vivado segfaulting
05:26
dmj_nova
do we have logs for this?
05:28
dmj_nova
did the license and command line tools work for them?
05:32
Bertl
The bigger problem that I have is that the 2013.3 doesn't work with ubuntu 13.10 (it is true that it is not officialy supported)
05:32
Bertl
it crashes when I launch, coredump without any error log, I'm going to post on xilinx forum to know if it is a know problem
05:32
Bertl
this is all I noted from the discussion
05:36
dmj_nova
ah
05:37
dmj_nova
will have to consider a workaround then
05:48
dmj_nova
who had the problem?
05:49
Bertl
didn't record that and I do not remember
05:49
dmj_nova
ok
05:50
Bertl
but if he posted on the forums, it should be easy to find
05:53
dmj_nova
though that's vivado
05:53
dmj_nova
I think I used ISE
05:54
Bertl
FWIW, we switched to vivado two months ago
05:54
dmj_nova
ah, okay
05:55
dmj_nova
so I need new tools anyway
05:55
dmj_nova
haven't contributed much since I've been busy writing a gstreamer library
05:55
dmj_nova
how much overlap is there between the two?
05:56
Bertl
the VHDL is roughly the same :)
05:56
dmj_nova
how about the compiling tools?
05:56
dmj_nova
and such
05:57
Bertl
basically all is TCL based in vivado, which simplifies command line solutions
05:57
dmj_nova
why is TCL so popular?
05:57
Bertl
probably because it is easy to integrate in proprietary solutions ...
05:57
dmj_nova
also tcl/tk is an abomination
05:58
dmj_nova
all the worst GUIs I've seen were made with it
05:58
dmj_nova
makes GIMP look like an icon of UX design

okay, will see if he got it working

hi se6astian
14:43
Bertl
PhilippeJ: I'm good, thanks for asking. not fully awake yet though :)
14:44
se6astian
hello!
14:44
se6astian
I have a nikon F65 in my hands
14:44
se6astian
now the exciting moment of taking off the ring and seeing if it does match what we need...
14:44
PhilippeJ
hahaaa
14:45
se6astian
the poor guy I got it from said "there are even batteries in it already" :)
14:46
Bertl
well, I probably would have checked the ring there and asked him to take the rest of the case back and sell it again :)
14:47
se6astian
yes, here I dont need it anymore, there are even the batteries inside it still ;)
14:47
se6astian
Bertl, would you be so kind to dig out the scan you made of the ring on your adapter
14:47
se6astian
so I can easily compare them
14:47
Bertl
sure, sec

15:05
se6astian
they "seem" to be identical
15:06
Bertl
yep, looks good! well done!
15:07
se6astian
thanks, I now placed the images on top of each other and kept switching between them
15:07
se6astian
they are indeed identical
15:07
se6astian
unless there are some sub millimeter differences somewhere
15:08
se6astian
but I would say there is a high chance this ring will fit on the adapter
15:08
Bertl
I really doubt that, wouldn't make too much sense
15:08
Bertl
(sub milimeter differences)
15:08
se6astian
hopefully ;)
15:08
se6astian
the guy I bought the camera from for 15 said he has another one of the same model in case I am interested
15:08
se6astian
I guess we are interested
15:09
se6astian
but lets put the parts together once the firstcut shipment arrived
15:09
Bertl
yup, agreed
15:11
Bertl
ah, just saw, then sensor arrived today, I'll have to check it out tonight I guess :)
15:12
se6astian
hurray
15:12
Bertl
so I'd say, end of the week, we should have our second alpha prototype unit!!
15:14
se6astian
\o/!
15:15
se6astian
did you lasercut the enclosure already?
15:15
Bertl
nope, still on my todo
15:15
se6astian
how about the metal part?
15:16
Bertl
I prepared the backup plan
15:16
se6astian
what exactly is the backup plan?
15:17
Bertl
just a metal piece to attach to the baseplate, no fancy L
15:18
Bertl
after the attempts to mill the holder failed for you and mars_
15:18
se6astian
baseplate = tripod baseplate, right?
15:18
Bertl
yup
15:18
se6astian
and the other side attaches to the top acrylic glass or to the lens mount?
15:19
Bertl
the idea is to lock it at the bottom of the acrylic case
15:20
Bertl
but feel free to pick up the L shaped holder once again ...
15:20
se6astian
well lets try the simple version first
15:22
Bertl
yes, I thought we can always 'upgrade' if we need to
15:22
se6astian
exactly
15:32
Bertl
according to the tracking, the lens mount from firstcut should arrive today as well
15:53
se6astian
wonderful
15:55
Bertl
well, let's see, sometimes they screw up, sometimes the tracker is just wrong :)

FergusL
hi here
17:07
Bertl
hey FergusL!
17:08
FergusL
is there a specific german and english expression for the party one hosts to celebrate moving in a new flat ?
17:08
FergusL
or house
17:08
Bertl
a house warming party?
17:11
Bertl
in german, all I know is 'Einweihungsparty'
17:11
FergusL
maybe ! in french it's "pendre la crémaillère", which translate to "hang the pothook", that means hanging the pothook above the fireplace so as to hold pots and cook something on the fireplace
17:16
Bertl
I guess in the spirit they are the same, maybe just the timing is different
17:20
Bertl
the lens mounts just arrive, first impression is good
17:20
Bertl
will check the tap drills and then take a picture/scan
17:20
FergusL
that's what you were discussing earlier ?
17:23
se6astian
great!
17:24
Bertl
FergusL: yep
17:26
Bertl
yeah drills look fine so far, only the holes for the bayonet ring are a little shallow, but that is a design problem I obviously missed
17:26
Bertl
but not a problem IMHO
17:39
rexbron
Bertl, se6astian: Re: sub-millimeter differences in lens mounts. They do matter! When I prep a camera, the flange focal distance needs to be within 0.02mm of spec, otherwise my focus marks are off
17:40
rexbron
and depending on the lens design, those 0.02mm is enough to throw the lens way out
17:40
Bertl
yes, we figured that the focal distance needs to be very close, but at the moment it isn't that important as long as we are able to focus at all
17:41
rexbron
Bertl: ok :)
17:42
Bertl
to be precise, we tested that with a camera by adjusting the distance by only a fraction of a milimeter
17:42
rexbron
Bertl: the other advantage of a professional mount like PL is that there are many tools available for making sure lenses and camera mounts are in spec. With stills, it's almost non existant. An autofocus sensor has no idea what distance it focuses to, it just says "Yep, that looks in focus"
17:43
rexbron
Bertl: if you are eye focusing, and especially with the short focus throws of stills lenses, then even 1 or 2 mm will still be able to focus an image at some distance in the range of the lens
17:44
rexbron
have you ever seen a lens collimator? It allows you to actually check focus at infinity (as counter intuitive as that sounds)
17:44
Bertl
yes, the only case we identified as problematic is when the lens mount distance is too large, because then the focus on infinity will not work
17:45
rexbron
Bertl: as a focus puller, you also want the hard stop at infinity to actually be infinity :P
17:45
Bertl
I can imagine that :)
20:23
Bertl

23:14
Sasha_C
How are you today?
23:15
Bertl
great, thanks! we got the new lens mounts (still have to upload a picture) and the new sensor from cmosis
23:27
Sasha_C
Congratulations! So the lens is firmly fixed to the main body now?
23:28
Bertl
not much changed in this regard, the only difference is the material and a few adjustments to match the sensor better
23:29
Bertl
but it means, that we will soon have a fully working alpha prototype which can almost be used like a normal camera
23:30
Bertl
(should be ready end of the week if all goes well)
23:52
Sasha_C
Like music to my ears :)
23:52

Let me know when you think it'd be good to write up another news update for the blog
