morning folks!

hi
14:59
se6astian
hi LordVan!
14:59
se6astian
do you remember I asked some time ago if your laser can cut very thin steel sheets if sandwiched in other materials (wood or other metal) - did you have a chance to try already?
15:00
se6astian
0.01mm, 0.02mm or 0.03mm for example
15:13
LordVan
yeah taht is not goign to work it'll just be soldered together 90% of the time
15:14
LordVan
so even if it was done you'D have to produce a lot more than are usuable afterwards
15:14
LordVan
so not really something feasible
15:58
se6astian
right, thanks for checking!

MEETING TIME
17:00
se6astian
who is here?
17:01
Bertl
is here ...
17:03
se6astian
any news Bertl?
17:03
Bertl
yes, this time I have some ;)
17:03
se6astian
great!
17:03
se6astian
please share
17:04
Bertl
well, first I almost completed two ZIF SFEs (all parts except for the HD connectors are done)
17:04
Bertl
so I'll probably finish them up tonight and get them tested tomorrow
17:05
se6astian
excellent!
17:05
Bertl
then, when searching for cables for a project of mine, I stumbled over a chinese company called 'Twozoh' which produces all kinds of HDMI cables
17:06
Bertl
and in particular, two of their models caught my attention
17:06
Bertl
one is labeled 'ultra thin HDMI cable' and I immediately ordered some samples there as the cables are quite cheap and really very flexible and thin
17:07
Bertl
they are thinner than many micro USB cables I've seen and they claim 4K at lengths up to two meters
17:08
Bertl
and I thought those might be perfect for conencting the Beta with the Recorder or Preview Monitor
17:08
se6astian
oh!
17:08
se6astian
sounds very good
17:08
Bertl
I plan to test them in the next few days
17:08
se6astian
as stiff and bulky cables are a major headache for me currently with the recorder enclosure
17:08
Bertl
yeah, if they work, you'll love them
17:08
se6astian
they arrived already?
17:09
Bertl
I got two of the three samples I've ordered already
17:09
Bertl
the other model they sell are fiber optic HDMI 2.0 cables
17:09
Bertl
which are available up to 150m
17:10
Bertl
but I didn't order any of those yet because they are rather expensive
17:10
Bertl
(the flexible ones are quite cheap)
17:10
se6astian
is it this model? https://www.amazon.de/-/en/Twozoh-Ultra-Cable-Flexible-Supports/dp/B09FT1MNSC
17:10
Bertl
yes
17:11
se6astian
perfect
17:11
se6astian
very curious about the signal quality
17:11
se6astian
what price did you pay?
17:11
se6astian
because 10⬠on amazon isnt that great
17:11
Bertl
I ordered them from amazon so about 10 EUR it was :)
17:11
se6astian
ah, right :
17:11
se6astian
)
17:12
Bertl
that's it from my side for this week
17:14
se6astian
many thanks
17:14
se6astian
what are you thoughts about cables like this? https://www.aliexpress.com/item/1005002899519702.html
17:14
se6astian
I assume the lack of shielding makes this a bad choice
17:15
Bertl
I've considered those but there are a bunch of potential issues I see with them
17:15
Bertl
first, as you mentioned, shielding can be a big issue there
17:16
Bertl
then, having several connectors and signal transitions (HDMI to PCB, PCB to FPC, FPC to FFC and the same on the other end in reverse)
17:17
se6astian
right, so I better stay away from those
17:17
Bertl
but we could certainly test those as well
17:17
se6astian
1080p60 is a rather "light" challenge for HDMI I guess
17:17
se6astian
so it could also just work?
17:18
Bertl
of course it could just work
17:18
se6astian
ok, maybe I will order one of those then :)
17:19
se6astian
quick updates from me:
17:19
Bertl
as I said, we can certainly test them, we have all means to evaluate cables now with the hash based tests
17:19
Bertl
(at least for our purpose ;)
17:19
se6astian
as you probably noticed the CCC talk last week was a full success
17:19
se6astian
lots of questions in the Q&A afterwards
17:19
se6astian
and a few new visitors to IRC as well
17:20
se6astian
the video should now go online soon as well
17:20
se6astian
I 3d printed a bracket for the ZIF socket today but because there is almost no space for it between the skeleton frame and the ZIF socket I was skeptical and indeed its too fragile
17:21
se6astian
https://cloud.apertus.org/index.php/apps/gallery/s/aroXPrykksDCnwk#IMG_20220103_174945.jpg
17:21
se6astian
or the shape not suited for SLA printing
17:22
se6astian
so I was not thinking about laser cutting a black 0.5mm acrylic sheet instead and gluing it on the ZIF socket with a tiny drop of glue in two corners
17:22
se6astian
*now thinking
17:23
Bertl
what
17:23
se6astian
on another project front I started 3d printing a new axiom recorder enclosure (because the connectors and bulky cables are really no fun
17:23
Bertl
*what's the advantage over index pegs?
17:23
se6astian
one beta dev kit should also be ready to ship to oscar in belgium in the coming days
17:24
se6astian
that are the topics from my side so far
17:25
se6astian
I am open to see the index pegs idea in action as I don't really know how its gonna look like
17:25
se6astian
I already shared my concern that blocking certain holes on the ZIF will not be obvious to users inserting the sensor but maybe I get convinced when I see it
17:26
Bertl
well, it's gonna look like a closed pin hole ;)
17:26
Bertl
potentially with some bright color to notice it :)
17:28
Bertl
anyway, yes, we can do some tests there as well ...
17:28
se6astian
great
17:28
se6astian
anyone else with topics or questions to share/ask
17:30
se6astian
then MEETING CONCLUDED, thanks Bertl and I hope to see more people around here again soon!
17:30
Bertl
thanks for the moderation!
17:50
Bertl
