MEETING TIME - welcome everyone to libera our new host
17:00
se6astian
who is here?
17:00
Bertl
is here ...
17:00
bluez
is here
17:00
Dest123

se6ast1an
Dest123: would you like to start?
17:01
Dest123
sure
17:01
metaldent
is present
17:01
Dest123
So the last couple of days I was working on the deserialized data of the sensor.
17:02
Dest123
To be specific, the control channel and the training data, which are nearly done.
17:02
Dest123
the control channel conveys status information on the validity of the data on the data channels,
17:02
Dest123
supporting the 5 output modes.
17:02
eppisai
is here
17:03
Dest123
I just need to generalize the case of FVAL signal (Indicating the validity of the read-out of a frame) other than that,
17:03
Dest123
it completely conveys the output data validity.
17:03
Bertl
care to elaborate shortly on the 5 output modes you mentioned?
17:04
Dest123
sure
17:04
vup
is here
17:05
Dest123
sending the data using 32, 16, 8, 4, 2, 1 channels
17:05
Dest123
6* output modes, sorry for that
17:05
se6ast1an
changed nick to: se6astian
17:05
Dest123
each mode will require different data on the control channel
17:06
Dest123
should I divulge more into it?
17:07
Bertl
nah, tx
17:07
Bertl
we also have 64 channels btw
17:09
Dest123
yes but if I understood correctly the control data won't change if only one or both sides were used
17:09
Bertl
correct
17:09
Dest123
DVAL and LVAL data for that matter
17:09
Dest123
ok then, as for the data training,
17:10
Dest123
to synchronize the receiving side with the output data, a training pattern is sent on the data channel when there is no valid image data to be sent.
17:10
Dest123
the module handles and sends both the training patterns through different operating conditions. i.e. Idle, overhead time
17:11
Dest123
both modules are supposedly finished, just need to do one more test, but my simulator crashed again this morning.
17:11
Dest123
hope I get this fixed by tonight.
17:11
Dest123
that's it for me :)
17:11
Bertl
excellent!
17:12
se6astian
many thanks Dest123!
17:12
se6astian
eppisai: you are next!
17:12
eppisai
Hi!
17:13
eppisai
So last week, I had extended display function for lcd and added transition manipulation.. in the firmware
17:13
eppisai
Like we had in previous version of remote
17:14
se6astian
did you push code to your github repo?
17:15
eppisai
Yes.. it's under Transition-Task branch in my fork..
17:15
eppisai
Currently using phone because outside so will share the link soon :)
17:15
se6astian
thanks
17:16
eppisai
Besides need to improve on it, and adding option for controlling transition speed from UI as BAndiT had suggested
17:16
eppisai
That's it :)
17:17
se6astian
before you dive into an speed changes lets verify its working as intended
17:18
se6astian
Bertl: is the remote remote webcam working already and remotely accessible?
17:18
eppisai
Yea.. that's my top priority right now
17:18
Bertl
we do not have a dedicated remote lcd webcam
17:19
Bertl
the webcam which overlooks the entire remote setup is working
17:19
se6astian
does it "see" the remote lcd?
17:19
Bertl
IIRC, BAndiT1983 planned to do a direct frame buffer readout via serial/usb last year, that might be better for actual testing
17:19
Bertl
yes, it can 'see' the remote lcd, but it is not very detailed
17:20
Bertl
(only makes up a small portion of the frame)
17:20
se6astian
lcd buffer read out is not finished to my knownledge, also would only wokr on single images, not viewing an animation
17:21
se6astian
so the webcam would probably be "good enough" to see a sliding animation that goes over the entire lcd
17:21
Bertl
probably
17:21
se6astian
eppisai: can you you get set up with help of bertl to access the webcam and post a screenshot then?
17:22
eppisai
Ohk! :)
17:22
se6astian
thanks, bluez you are up next
17:23
bluez
yep! some quick updates from me:
17:23
bluez
I was able to optimize the read/write speed for a register by a large factor
17:23
bluez
read was reduced from around 1 min to 3 secs! similarly for write
17:23
bluez
for this i generated a minimal lookup database at build time, i.e. with info only about slices which are actually used by the design
17:24
bluez
it can be optimized further as well, and it's necessary as we will need to update a lot of registers at once
17:24
bluez
other than this, i did some cleanup here and there, and added some basic build/run instructions
17:24
bluez
will add more documentation soon
17:24
bluez
https://github.com/Swaraj1998/reg-test
17:24
bluez
that's it from me for now!
17:25
se6astian
many thanks!
17:25
Bertl
great! tx!
17:25
bluez
:)
17:25
se6astian
metaldent: your turn
17:26
metaldent
hi, last week Bandit and I were discussing about rendering the remote visualizer into 3d
17:26
metaldent
so i looked at some emscripten docs and tutorials to understand it better
17:27
metaldent
i also found this similar lab task -> https://lab.apertus.org/T1178
17:27
metaldent
so this week i'll be working more on this, that's it from me!
17:27
se6astian
can you elaborate about the 3d rendering, not sure I follow
17:29
metaldent
it'll be something like you guys did with the 3d cad viewer
17:29
metaldent
but of the visualizer, am still investigating how to do that
17:29
se6astian
interesting
17:30
se6astian
many thanks
17:30
se6astian
vup, please share your news with us!
17:30
vup
sure
17:30
vup
not too much to report, uni held me pretty busy
17:31
vup
but i made some progress on the layer I am currently designing (with a lot of help from anuejn) to simplify some things we are currently doing in nmigen
17:31
vup
I won't bore you with the details this time :)
17:32
vup
But the prototype is now starting to take shape, and we can hopefully replace some aweful code in the nmigen-gateware with it
17:32
vup
This is a basic usage example: https://paste.niemo.de/nojuranazu.py
17:33
vup
If anybody is interested in this more, I guess ask me questions either now or after the meeting :)
17:33
vup
Anyways, this is it from me this week
17:33
vup
Oh I nearly forgot
17:33
se6astian
nice, many thanks!
17:34
vup
we also fixed the CI for the nmigen gateware, so we now test synthesis / bitstream generation with vivado again
17:34
se6astian
quick updates from me
17:34
vup
and also generate the docs again
17:34
se6astian
hardware production update: all the hardware was collected from tele last week and handed over to Bertl last thursday
17:35
se6astian
he started inspecting it over the weekend, he will share more about this I assume
17:35
se6astian
I am now in the middle of counting and listing all the remaining components tele returned to us
17:35
vup
the latest docs can be found here: https://docs.niemo.de/naps/commit/latest/index.html
17:35
se6astian
a huge box
17:36
se6astian
regarding our IRC move you probably noticed that freenode made it easier/quicker for us
17:36
se6astian
as it bulk closed all channels that had "libera" in the topic there
17:36
se6astian
so our channel there is deserted now as they moved it to ##apertus
17:37
se6astian
no big deal, this is our new home here
17:37
se6astian
website has been updated accordingly
17:37
se6astian
need to check wiki and gsoc related info as well though
17:37
se6astian
to make sure freenode is not still listed there by accident
17:38
se6astian
another topic is the 3d cad viewer progress
17:38
se6astian
latest state is here:https://apertus-open-source-cinema.github.io/cad-3d-viewer/
17:38
se6astian
latest additions are layout fine tuning fixes/updates
17:38
se6astian
the light/dark switch should work for most elements now
17:39
se6astian
font size and spacing was updated
17:39
se6astian
external links added to open the source or go to apertus.org
17:40
se6astian
BAndiT1983_: also added a model ID GET parameter in URL
17:40
se6astian
so you can link to a specific model now, example in https://lab.apertus.org/T1246
17:40
se6astian
https://apertus-open-source-cinema.github.io/cad-3d-viewer/?part=axiom_lens_cap_v01
17:40
se6astian
BAndiT1983_: has a few open tasks still, listed in rightmost coloumn of this workboard: https://lab.apertus.org/project/view/16/
17:41
Bertl
can 3D models be downloaded in some way from the viewer?
17:41
se6astian
good idea
17:41
se6astian
not yet
17:41
se6astian
but would be a great addition
17:41
se6astian
will add to workboard after meeting
17:42
se6astian
and we posted progress on twitter and it was retweeted by onshape among others which made the tweet rather succesful
17:42
se6astian
https://twitter.com/ApertusOSCinema/status/1397848942973423618
17:42
se6astian
almost 8000 impresions by now
17:42
se6astian
no threejs retweeted, not onshape, sorry
17:43
se6astian
next topic is the youtube terms and conditions change
17:43
se6astian
they now reserve the right to monetize our videos
17:43
se6astian
which we do not monetize ourselves
17:43
se6astian
so they can play ads, insert them during the video, etc.
17:44
se6astian
the first impulse was to consider monetization ourselves to at least maintain control
17:44
se6astian
but thats not gonna work out as we do not reach the 4000h viewtime per year youtube set as minimum requirement
17:44
se6astian
our videos are too short and we do not post enough videos
17:45
se6astian
so we will have to live with yt monetizing our content for now
17:45
se6astian
they might not actually do it
17:45
se6astian
and in addition we can consider/discuss alternatives
17:46
Bertl
link to a youtube ad remover ;)
17:46
se6astian
like peertube is already being mentioned a couple of times (by rex in particular who did not do the freenode -> libera move )
17:46
se6astian
yeah, me and I guess many of you never see ads anyway with adblock
17:47
se6astian
so far the peertube efforts were not going anywhere because nobody wants to deal with installing/maintaining it
17:47
se6astian
we could get a separate server instance for it
17:47
se6astian
but requirements were not 100% clear yet
17:47
se6astian
peertube hosting exists, eg. https://app.spacebear.ee/plans
17:48
se6astian
but there its rather expensive for what you get
17:48
se6astian
so does anyone have an opinion about this or whats to suggest/discuss?
17:48
se6astian
*wants to
17:48
tpw_rules
do people still use vimeo?
17:48
se6astian
any soluton
17:49
se6astian
yes vimeo has turned more towards profesional content creators
17:49
se6astian
who pay for storage space to upload videos basically
17:49
tpw_rules
ok
17:49
se6astian
so its more like a video hosting platform, no ads but paid by creators
17:49
se6astian
also an option for our videos
17:50
vup
what about just using a existing peertube instance?
17:51
se6astian
also an option
17:51
se6astian
blender has a big one AFAIK
17:52
se6astian
technical university vienna as well, maybe we know someone there, Bertl?
17:52
se6astian
https://tube1.it.tuwien.ac.at/about/peertube
17:52
Bertl
maybe
17:53
vup
using a existing instance might not offer the "branding" opportunities hosting one ourselves has we might not need that :)
17:53
Bertl
Nur für universitäre Zwecke der TU Wien, insbesondere Lehre.
17:54
eppisai
I had first heard about Apertus from a quora , and had seen videos of Sebastian explaining what Axiom beta is.. I think if it's about reaching to people youtube might be best option still..
17:54
se6astian
yeah, more interesting to get in touch with them than to use their directly
17:54
se6astian
TU vienna
17:55
se6astian
eppisai: I agree, youtube is also about the subscribers, the social network side, the video suggestions, etc.
17:55
Bertl
I doubt youtube will suggest our videos :)
17:55
se6astian
I would do a parallel approach where we embed videos on the website on peertube but might still also upload to youtube
17:56
se6astian
Bertl: it already does
17:57
Bertl
never got any suggestion in this regard
17:57
eppisai
Actually I got a suggestion once on my feed about the ad campaign of apertus.. where there was a news anchor reporting about disrupt in cinema technology..
17:57
se6astian
such a new anchor nerd!
17:57
se6astian
*news
17:58
Bertl
that was the crowdfunding video
17:58
se6astian
if you watch https://www.youtube.com/watch?v=kx1y0tJcXeU, I see a Team Talk suggestion on the right
17:58
eppisai
:D :D
17:58
se6astian
but it might be different for another users
18:00
tpw_rules
yeah i don't get any apertus related recommendations
18:01
se6astian
right, so to conclude the topic for now, we can continue to discuss this further if anyone has ideas/suggestions
18:02
se6astian
but currently it seems we will continue using yt and see what happens
18:02
se6astian
maybe a parallel other platform in addition
18:03
se6astian
thats it from my side
18:03
se6astian
Bertl: please close us!
18:03
Bertl
thanks for the 'quick' update ;)
18:03
Bertl
we are missing some GSoC students today as it seems
18:03
tpw_rules
i am here!
18:04
Bertl
vnksnkr: manav: where art thou?
18:04
vnksnkr
I am here :)
18:04
Bertl
ah, excellent, want to report what you need last week?
18:04
Bertl
*did
18:05
Bertl
tpw_rules: I guess you have a few things to report as well, IIRC?
18:05
vnksnkr
sure I started working on the gateware properly as I mentioned last week
18:06
vnksnkr
Still more are left to be done before sharing the simulation results..will be sharing them soon :)
18:07
Bertl
okay, great! thanks!
18:07
tpw_rules
hello, yes i can
18:07
Bertl
please do so ;)
18:07
vnksnkr
Also discussed with Bertl on implementing the communication side that's it from me :)
18:08
tpw_rules
i got the development environment set up and compiled some of the nmigen applets and tested them on the betas to validate my setup and the remote access. everything worked great!
18:08
tpw_rules
my next step is to prepare some of the pin connector definitions required to access the sensor, then start work on the spi communication for setting sensor parameters
18:08
tpw_rules
that should be it from me
18:08
Bertl
excellent! tx!
18:09
Bertl
btw, I should have an SPI PMOD gizmo somewhere which could be used via one of our PMOD plugins
18:09
Bertl
that might help with the SPI directly attached to the Zynq if you still want something to test
18:10
Bertl
(but I have to find it first ;)
18:10
vup
nice
18:10
Bertl
okay, so I spent most of the time last week with remote setup and introduction for our GSoC students
18:10
tpw_rules
depends on how long you think it will take to get the sensor ready
18:11
Bertl
this really depends on how se6astian wants to proceed with the TELE PCBs
18:11
Bertl
which was where I spent most of my free time during the weekend on
18:12
Bertl
the detailed inspection revealed a number of actual and potential issues, especially with the manually soldered parts
18:12
Bertl
there are some cold joints and a bunch of misaligned connectors
18:13
tpw_rules
that is unfortunate
18:13
Bertl
and there are some accidental solder 'spills' on components
18:14
Bertl
that said, the parts which got automatically placed and reflowed have pretty good quality
18:14
Bertl
(i.e. matches what we had in our test PCBs and is more than adequate for our purpose)
18:15
Bertl
I will continue creating documentation of the review and also start testing the boards tonight
18:16
Bertl
(that is electrical and functional tests)
18:16
Bertl
so we will know more in the next days
18:17
Bertl
that's it from my side for this week
18:17
se6astian
many thanks!
18:17
se6astian
anyone ele who still wants to report/discuss anything?
18:18
se6astian
right ten, many thanks everyone who participated!
18:18
se6astian
MEETING CONCLUDED!
18:19
Bertl
thanks for hosting!
18:19
se6astian
my pleasure!
18:22
vup
tpw_rules: Ok, are there any open questions / anything you would like to discuss?
18:23
