meeting time!
16:00
se6ast1an
who is here?
16:00
Bertl
is here ...
16:00
BAndiT1983
am here
16:00
se6ast1an
great
16:02
se6ast1an
seems its a small circle today
16:02
se6ast1an
BAndiT1983: any news to report?
16:04
BAndiT1983
sorry, not much, was investigating the firmware performance and preparing for gsoc2020
16:04
BAndiT1983
but in the last days other things came in-between
16:05
BAndiT1983
waiting for submissions from students, before doing bigger steps in the firmware/bootloader
16:05
BAndiT1983
that's it from me
16:05
se6ast1an
right, thanks
16:05
se6ast1an
Bertl: you have some things to share don't you?
16:06
Bertl
well, mostly GSoC preparations as well here, but I managed to also whip up a bunch of PCBs for this purpose and make some progress on the ABCP PB
16:06
Bertl
I've updated the Axiom Remote design to match the current state of the Prototypes we already have
16:07
Bertl
and extend that with a remote control option
16:07
Bertl
the remote for the remote :) is basically pads on the PCB to connect each and every button or rotary encoder
16:08
pratyush
joined the channel
16:08
Bertl
which then, thanks to another PCB which can be attached at the bottom of the Remote, allows to remotely press the buttons and spin the dials
16:09
Bertl
in addition to that it allows for side-channels to the PIC16s and programming of the PIC32
16:09
Bertl
the design works together with a remote shield for the Axiom Beta, so it should be easy to create a remote controlled setup at the hub
16:11
anuejn
is here
16:11
Bertl
on the USB3 front, my Test PC suddenly died, still not sure what is actually broken
16:11
Bertl
but I replaced the motherboard and the graphics card and I'm working on getting the replacement up and running
16:12
se6ast1an
do you still need my motherboard?
16:12
Bertl
it wouldn't hurt to have a spare, yes
16:13
Bertl
for the ABCP power board, the basic testing except for the switchers is done, and I'm able to program the new PIC16F15325 on the board
16:13
Bertl
so the next step there is to write some power management and control interface to get the switchers tested
16:14
Bertl
information gathered during the PB assembly was already incorporated into an updated PCB layout which is currently processed by OSHpark
16:15
Bertl
those were only minor adjustments to improve the layout nothing which would change the functionality
16:15
Bertl
I think that's it from my side for today
16:16
se6ast1an
thanks, "write some power management and control interface to get the switchers tested" is a not too complicated task I assume?
16:17
Bertl
not as complicated as writing the gateware for the Axiom camera :)
16:17
se6ast1an
obviously
16:18
se6ast1an
when do you think you can say if the switchers work or not?
16:18
se6ast1an
and what can only be tested after the new PB arrives?
16:18
Bertl
we should know this week I'd say
16:18
se6ast1an
great
16:19
Bertl
we cannot test the interaction between the existing elements on the PB and the new parts before the new PB arrives
16:19
se6ast1an
right
16:19
Bertl
but it should be possible to get an idea by using the current prototype together with an old power board
16:20
se6ast1an
do you want to say a few words about the FFD measurement efforts that we want to focus again on now?
16:20
Bertl
if you like me to, sure ...
16:20
se6ast1an
please
16:21
Bertl
well, it seems to be important for the ABCP to measure or at least compare the focal flange distance (FFD) on/between different cameras
16:22
Bertl
a further goal is probably to also measure any angular mismatch between sensor and image plane
16:23
Bertl
so we devised a bunch of methods to do those measurements and we plan to prepare a test setup and do some testing to figure out which one is best suited for our purpose
16:24
Bertl
a very appealing and probably quite simple approach is to use the sensor feedback to do the measurements
16:25
Bertl
e.g. have a setup with a grating or mask with holes which works like a pin-hole lens and two or more different colored light sources projecting through this mask/grating onto the sensor
16:26
Bertl
then inspect the pattern on the sensor (ideally by simply reading out the sensor), do some math and get the proper distance as well as any angle between sensor and measurement setup
16:27
Bertl
naturally this requires precise components to attach to the cameras e-mount as well as a way to measure the initial distance
16:27
Bertl
(i.e. mostly works as calibrated instrument)
16:28
Bertl
guess that's it?
16:28
se6ast1an
perfect thanks
16:29
se6ast1an
so further tests will be done plus some mechanical parts designed/manufactured

se6ast1an
quick update from me
16:29
se6ast1an
new screws that I ordered last week arrived
16:30
se6ast1an
they solved the issue of the screwhead standing out of the enclosure

3rd picture = new screws
16:30
se6ast1an
torx everywhere
16:31
se6ast1an
I also received dowel pins for the lens mount assembly, unfortunately installing them showed two missaligned holes, need to verify now if the drawings are incorrect or the manufacturing is to blame
16:32
se6ast1an
Fabian Puttinger visited us today in the AXIOM office and brought his stereo 3D rig he built

https://cloud.apertus.org/index.php/apps/gallery/s/7JZd4Yd9pfszX3a#
16:32
se6ast1an
he wants to collaborate to build a second generation from metal and for larger cameras, like the AXIOM :)
16:32
se6ast1an
and open source/open hardware everything of course
16:33
se6ast1an
I see he already joined the wiki and will draft name/plan for this project soon, then we can see who is interested in participating
16:34
se6ast1an
its basically an adjustable orientation/distance beamsplitter rig for 2 cameras, so there might be many more interesting applications
16:34
se6ast1an
beside stereo 3d
16:34
se6ast1an
multispectral, HDR, etc.
16:35
se6ast1an
thats it from my side
16:35
se6ast1an
anyone else who wants to share some things?
16:35
se6ast1an
vup, anuejn?
16:36
anuejn
well, i dont have much to report
16:37
se6ast1an
any news for the vienna hackathon plans?
16:37
anuejn
currently we are still working on building axi stuff
16:37
anuejn
but not much very visible progress
16:37
anuejn
huh no, i guess
16:38
anuejn
thats it from my side
16:38
se6ast1an
thanks!
16:39
se6ast1an
ok, anyone else?
16:39
se6ast1an
otherwise we can conclude early today
16:40
se6ast1an
right, meeting concluded then, thanks everyone!
16:40
Bertl
you're welcome!

I have a new idea which I would like to work on. I intend to create a real-time face tagging system that could tag faces and that could be used in autofocus.I want also to create a filtering algorithm that could add special effects to pictures and some more AI-related features like background blur etc.
18:45
Bertl
sounds interested ... where do you plan to implement that?
18:45
Bertl
*interesting

pratyush
I wolud like to implement it as a part of axiom Remote
18:51
Bertl
you are aware that the Axiom Remote uses a PIC32 MCU?
18:53
pratyush
yes
18:53
pratyush
its an arm based mcu
18:53
Bertl
so you plan to implement real-time face recognition and filtering on an MCU?
18:54
Bertl
and the PIC32 is MIPS, not that this would matter
18:55
pratyush
it check out the clock speed its only 80Mhz
18:55
pratyush
i think thats not possible
18:55
pratyush
to implement
18:57
Bertl
it's actually a PIC32MZ, so the clock speed tops out at 250MHz
18:58
Bertl
but I doubt that you will be very successful with 512KB memory :)
19:00
pratyush
I do agree
19:02
pratyush
But i checkout the website of tensorflow lite and the said that ESP32 like mcu could run tf-lite
19:02
pratyush
which has similar specifications like PIC32MZ
19:06
Bertl
well, I won't keep you from trying :)
19:07
pratyush

hey BAndiT1983|away, what is expected output after building remote_firmware_visualiser
22:16
sergio____
?
22:16
sergio____
hey Bertl_oO can you help me with this ?
22:17
Bertl_oO
not really, I'm only building the hardware :)
22:19
sergio____
okay then I will for BAndiT1983|away to revert back!! :)

you might want to get a real IRC client in the meantime, the web clients are notoriously unreliable, pick a free nick and register it with NickServ
