Bertl
morning folks!
05:58
Bertl
hey sab_123!
05:59
sab_123
hello
06:05
sab_123
you guys are based out of Vienna?
06:11
Bertl
se6astian is in Vienna, I'm nearby, other folks are spread all over the world
06:13
sab_123
Bertl, cool
06:13
sab_123
Bertl, sent you a pic of the board
06:15
Bertl
I presume you're the new intern then :)
06:15
sab_123
yep
06:15
sab_123
thats correct
06:16
Bertl
looks nice! what clock rates do you use un U4 and U15?
06:17
sab_123
It is configurable
06:17
sab_123
depends on the camera I2C conf
06:17
Bertl
maximum
06:17
sab_123
right now using parallel mode
06:18
Bertl
i.e. what I want to know is: for what maximum speed/clock/data rate is the board designed?
06:19
sab_123
i/p
06:19
sab_123
between 6 and 27Mhz
06:20
sab_123
o/p - It is supposed to do 98Mp/s
06:20
sab_123
so you see the length matching
06:20
sab_123
It is 4 layer
06:20
sab_123
Signal
06:20
sab_123
VCC
06:20
sab_123
GND
06:20
sab_123
Signal
06:20
sab_123
got some help for the board though
06:20
sab_123
FPC 0.5mm connector
06:21
Bertl
yeah, I was wondering about the (excessive) length matching
06:24
sab_123
done in kicad
06:26
Bertl
so you're now going to assemble and test it?
06:27
sab_123
thats going to be hard now
06:27
sab_123
I have to find some way to assembled this
06:27
sab_123
I dont have a stencil
06:28
sab_123
So I will have to get someone to do it for me
06:28
Bertl
doesn't look too complicated, i.e. should be fine for hand soldering
06:28
sab_123
never soldered stuff
06:28
sab_123
especially SMD
06:28
Bertl
are there parts on the backside?
06:28
sab_123
yes
06:28
sab_123
lots
06:28
sab_123
of decouling caps
06:28
sab_123
AMS1117
06:29
Bertl
okay, so nothing really problematic there either?
06:29
Bertl
like QFN or BGA or so
06:30
sab_123
no BGA
06:30
sab_123
TQFP 144
06:30
sab_123
Spartan 6
06:30
sab_123
i have to probably go to a mobile repair shop
06:31
sab_123
Those guys help me out
06:31
Bertl
https://wiki.apertus.org/index.php/AXIOM_Beta
06:31
Bertl
the blue boards were all hand soldered at some point
06:31
Bertl
s/blue/purple (of course)
06:32
sab_123
how do you do it?
06:32
Bertl
first, you need to know how to hold your soldering iron :)
06:33
Bertl
okay, seriously, it is not that hard if you know a few tricks
06:33
Bertl
but you should practice on a spare board with cheap components first
06:34
sab_123
if you have a stencil
06:34
sab_123
reflow is easy
06:34
sab_123
with hot air
06:34
sab_123
but dont have a stencil for this
06:34
Bertl
well, yeah, but stencils are overrated for prototyping
06:34
sab_123
let me share an interesting SOC with you
06:35
sab_123
whats your email
06:35
Bertl
the important thing for hand soldering is to know that liquid solder is a liquid with high surface tension
06:36
Bertl
so you can do all the stuff you would do with any other liquid, like 'wetting' pads or pins, and 'sucking' it 'dry' with some fabric
06:36
sab_123
Bertl, are you:
06:37
sab_123
herbert@13thfloor.at
06:37
Bertl
obviously I am
06:37
sab_123
Well
06:37
sab_123
I didnt know
06:37
sab_123
Bertl vs herbert
06:37
sab_123
close
06:37
sab_123
but just wanted to make sure I dont send documents to the wrong person
06:37
Bertl
you should read your email more carefully then :)
06:39
Bertl
and I don't mind much, but usually it's not a good idea to paste email addresses in a publicly logged channel, because it will for sure get picked up by a spam bot sooner or later
06:41
sab_123
ah
06:41
sab_123
okay
06:41
sab_123
sorry
06:41
sab_123
:-)
06:44
sab_123
yes
06:44
sab_123
read the email now
06:44
sab_123
did you take a look at that chip
06:45
sab_123
the chip is about 3-5USD depdning on type
06:46
sab_123
(1Gb vs 512Mb)
06:46
sab_123
RAM is built in
06:52
Bertl
yes, I've seen the chip (GM8136)
06:52
sab_123
ah
06:52
sab_123
okay
06:52
Bertl
but I haven't found publicly available documentation yet
06:52
sab_123
i sent it to you
06:52
sab_123
right now
06:52
sab_123
didnt you get it
06:53
Bertl
you have an url for the documentation?
06:54
sab_123
i sent the whole SDK to you now
06:55
sab_123
dont have something public,
06:55
Bertl
so how did you get it?
06:55
Bertl
(the documentation)
06:56
sab_123
do you have gmail account
06:56
sab_123
I would prefer to discuss it there
06:57
sab_123
or SKype

hi Bertl
08:58
Bertl
hey John_K! how's going?
08:59
John_K
not bad, got our custom adapter boards back
08:59
John_K
uploading a few photos now
09:07
John_K
https://kelley.ca/temp/Mavrx/
09:07
John_K
basically just RFE + PIC from Main board and no Dummy Interface board
09:08
John_K
Z was getting too high for our enclosure with the Dummy IF and we needed the 90 degree sensor rotation
09:08
Bertl
yes, I see, nice
09:09
Bertl
I presume the image data is processed in system?
09:10
John_K
captured and sent over ethernet to an ODROID XU4 with a USB3.0 attached Compact Flash card
09:10
John_K
3 Beta cameras to one ODROID
09:10
John_K
each capturing at around 1FPS at the moment
09:10
Bertl
I see, the gigabit ehternet is fast enough for you?
09:10
John_K
only because our application doesn't need higher frame rate
09:10
John_K
yes
09:12
Bertl
nice to see the first real adaptation of the AXIOM Beta!
09:12
John_K
:)
09:12
John_K
after validation on it is complete we'll get the design files posted
09:14
Bertl
excellent! would be nice to have an article about it as well, if possible
09:14
John_K
that sounds good to me, will run it by the team
09:28
Bertl
great! thanks!
09:32
John_K
so you recently had a meeting about Gamma?
09:42
Bertl
yes, we had an intermediate review from the EU
09:45
John_K
financial / progress review? or some sort of design review?
09:45
Bertl
progress and financial
09:46
Bertl
went very well
09:46
John_K
glad to hear!
09:47
Bertl
I think an article about that is in the works
09:47
John_K
from what little I've seen of it, gamma seems like a more complicated beast than beta?
09:47
John_K
ah, nice
09:47
Bertl
definitely
09:49
John_K
alright, time for bed here. Good night
