Bertl: Greets
03:39
Bertl
hey sb0! great to see you here!
03:39
troy_s
Bertl: What does sb0 do?
03:41
Bertl
a lot of nifty FPGA stuff, like this one: http://milkymist.org/3/mmone.html
03:43
Bertl
and an aggressive open source/open hardware proponent ... which I consider a good thing
03:50
Bertl
preparing my very tricky levitating chart setup now :)
03:54
sb0
troy_s, mostly http://m-labs.hk/gateware.html these days
03:55
sb0
as far as FPGAs are concerned
03:55
troy_s
Bertl: You mean to fix the blasted skew?
03:55
Bertl
for all kind of tests and adjustments
03:56
troy_s
sb0: Interesting stuffs.
03:57
troy_s
Bertl: Do you think we have a way forward to get a decent transformation matrix?
03:57
Bertl
we'll see, but I'm confident
04:24
Bertl
sb0: btw, when you've settled in, would you mind me asking a bunch of FPGA development related questions? after all, compared to you I'm an FPGA noob :)

morning S3bastian!
08:23
S3bastian
good morning!
08:24
S3bastian
the zyboboard arrived
08:24
Bertl
ah, so it got sent to you then?
08:24
S3bastian
yes
08:27
S3bastian
for the atomos connect converter I also packed the manual, it lists a good range of modes that it can convert on demand like 1080p60
08:27
Bertl
s/can/can't/ :)
08:28
Bertl
or did you have any success with 1080p60
08:28
Bertl
?
08:29
Bertl
btw, do we have a proper/working row/col noise config for your sensor?

morning SashaC!
08:39
S3bastian
I had no success but I also had no time to turn on the convertion modes
08:39
SashaC
morning Bertl. How are things?
08:40
S3bastian
Only the FPN config that you created in Berlin
08:40
S3bastian
Hi sasha

greetings Sebastian

FYI: latest nikon bayonet ring order looks good: https://cloud.gerade.org/index.php/apps/gallery/ajax/image.php?file=13ccf5ceb783775d7cffa126eec1cec5%2Falpha%2Fnikon-adapter01.jpg

troy_s: you spent weeks to mess it all up and now I shall fix it immediately :)
15:54
Bertl
but there are good news and bad news
15:55
Bertl
the IR theory doesn't really hold, there isn't much which passes both the cutoff and a 720IR filter, so I'm somewhat confident that stray IR is not the main issue
15:56
Bertl
OTOH, when testing, I found that there is some kind of saturation at the upper and lower end of the sensor scale, which seems to relate to the gain settings and offsets
15:58
S3bastian
troy_s: I saw you gathered lots of info on the calibration tools/processes, could you be so kind to transfer that knowledge into the wiki?
15:58
S3bastian
I have to leave now
15:58
S3bastian
see you!

so I think the main objective should be to keep the profiling between 1/3 and 2/3 (or even less) of the entire range
15:59
Bertl
at least for now, until we figure out where those effects come from
16:00
Bertl
I'll take a nap now, but I'll do some charts with the broken sensor later
16:06

troy_s
Bertl: The saturation issue is the one I think.
16:45
troy_s
Bertl: Seems to be supported by our rather anecdotal evidence of looking at the TI3s.
