morning folks!
05:46
comradekingu
good morning :)
05:46
Bertl
how's going?
06:00
comradekingu
Just had the flu, chopping wood at my cabin mostly, and rigging up sound-system
06:00
Bertl
welcome to the club
06:00
comradekingu
We have fiber and delivered post, so its remarkably good
06:01
Bertl
I'm still at 50% brain capacity :/
06:01
comradekingu
welcome to my life;)
06:01
comradekingu
Made some logos and written some prose
06:02
comradekingu
One got used http://flif.info/
06:02
comradekingu
:)))
06:03
comradekingu
I find the company of wild animals prefrable to the droves of humans in the city
06:05
Bertl
nice, although I had made it a block by using a | as L and the i at the same height (including the dot)
06:06
comradekingu
(took me a while to figure out you were talking about the logo)
06:08
Bertl
the logo? no no *G*
06:12
comradekingu
doing it that way ruins the flow, and there is no negative 14
06:13
comradekingu
and its a slection of different letters, as opposed to compressed ones
06:14
comradekingu
to do it you would have to start out with a bigger F and then end on a even smaller F
06:38
Bertl
how so?
06:57
comradekingu
So that it scales
06:57
comradekingu
from big to small
06:58
comradekingu
I like to put some intrinsic sense in my designs, you can see some here http://portfolio.anotheragency.no/
07:03
Bertl
I meant like this: http://vserver.13thfloor.at/Stuff/flif.png
07:08
comradekingu
I know, i have a draft like that
07:09
Bertl
so that had too little flow for you or what are you saying?
07:10
Bertl
don't get me wrong, I'm not criticising here, logos are a matter of personal taste ...
07:11
comradekingu
yes, it has no 14, and no splif, nor the flow. Flow is hard to explain, its about energy pointing in a pattern
07:11
Bertl
so what do you think of the AXIOM logo then? (just curious :)
07:13
comradekingu
the L i is a pair, a circle missing whats outside of it. The l i is two bars missing the dot
07:13
comradekingu
i like it, one of the reasons i like the axiom project so much
07:13
comradekingu
I know people say logos and such arent important, but to me it is, all details matter to me
07:15
Bertl
glad you like it then!

John_K
if I were to fab my own set of Axiom Beta PCBs, is there a stable (ish) set of schematics/board layouts that would be recommended
08:26
Bertl
yes, the latest ones are usually the best choice
08:26
Bertl
you can directly order the PCBs via OSHpark if you like
08:29
Bertl
(or you can make your own boards from the gerbers if you prefer)
08:29
John_K
ah yes, I see some new ones were just uploaded
08:29
John_K
is there much difference between r1.3 and r1.4 for the sensor board?
08:29
Bertl
nah, they were just shared, because I forgot to do so
08:30
Bertl
r1.4 adds some fixes to the cream layer, we have been working on that recently
08:30
John_K
I've got two CMV12000 sensors here and a microzed, looking to put them to good use and contribute where I can
08:30
comradekingu

08:30
John_K
cream layer?
08:30
Bertl
for the solder paste stencil
08:30
John_K
ahhh
08:31
Bertl
just let me know if you're missing anything, I'm sure we can provide it
08:32
John_K
good to know, does the VHDL live anywhere? I didn't see anything on the github project
08:33
Bertl
http://vserver.13thfloor.at/Stuff/AXIOM/BETA/cmv_hdmi3/
08:33
Bertl
yeah, the git repository needs some updating, but we haven't gotten to that yet either
08:38

08:39
John_K
which ZIF socket is being used for the CMV12000?
08:39
John_K
is it one of Andon's?
08:40
Bertl
nope, didn't even know andon had matching ZIF sockets
08:40
Bertl
it is a 604 microPGA socket normally used for processors
08:40
John_K
it doesn't appear to be specified in the sensor board BOM
08:40
John_K
oh

08:45
John_K
is the Andon socket guide for CMOSIS
08:45
Bertl
requires an account
08:45
John_K
ah, true
08:45
John_K
shouldn't to see the pdf
08:46
Bertl
and yes, we use the andon socket in the non ZIF version
08:46
Bertl
(which still needs to be updated to the latest changes)
08:46
John_K
ok
08:47
John_K
is the manufacturer and model of the socket 604 ZIF adapter being used documented somewhere?
08:47
John_K
or should I just ask? ;)
08:47
Bertl
just the ZIF is much more comfortable for swapping the sensor
08:47
John_K
yeah, that makes total sense
08:47
Bertl
it is a foxconn 604 mPGA socket and you can probably find it for a few bucks on aliexpress or so
08:48
Bertl
they come in different forms and shapes
08:49
Bertl
http://www.motherboards.org/images/reviews/hardware/1221_p3_3.jpg this is the shape we use
08:50
John_K
this looks to be a close match, http://www.aliexpress.com/item/FREE-SHIPPING-NEW-CPU-MPGA604-SOCKET/32373856482.html?spm=2114.01020208.3.1.eQvRbR&ws_ab_test=searchweb201556_1,searchweb201527_2_71_72_73_74_75,searchweb201560_9
08:51
Bertl
yeah, that one looks fine
08:52
John_K
ok cool
08:53
Bertl
the reflow is a little tricky, but the result can be easily verified with the [nm] version of the PCB
08:54
Bertl
(which allows access to the vias from the bottom side)
08:54
John_K
makes sense
09:10
John_K
thanks for the info Bertl, will be ordering a set of PCBs from OSHPark in the morning
09:11
Bertl
let me know if anything is not shared there, you might want to get one or two of the plugin modules as well
09:16
John_K
is the SD slot on the power board connected to the Zynq?
09:16
John_K
because all I really need for my application is a data SD card
09:16
John_K
don't need HDMI
09:18
Bertl
yeah, the SD slot is connected to the PS
09:18
Bertl
you might still want the triple PMOD plugin for debugging or so
09:19
Bertl
usually helps to have a few I/O pins easily accessible
09:19
John_K
