#apertus IRC Channel Logs

morning folks!

hey Frost_!

Hi Bertl!

Talk here?

Yes, I've noticed.

I have some skills in digital electronics (VHDL, FPGA, ...) and in programming languages (low/high level C/C++)

sounds good, you are from algeria?

geoip knows everything :)

so, do you have any areas you would like to work on?

I have an Altera DE2 board at my disposition (not that much, I know)

but I might be moving to France in a few months, get my hands on more hardware (camera sensors, fpga ...)

bascially FPGAs are all the same, it's not like with processors

exactly

so, back to areas of interest, is there something specific which interests you in the AXIOM?

makes sense ...

so you might want to look through open tasks in general, and some of the GSoC tasks in specific

like for example T721 or T731

wb Frost_

really sorry, there was a net cut.

(there are a number of good clients out there available for all platforms, like pidgin)

okay, downloading immediately, I don't usually use IRC

looks like :)

Riot gives push notifications on mobile. Aside from that I use Hexchat and AndChat.

haven't found T721 though

https://lab.apertus.org/T721

there is also T730 and of course older tasks as well as new things we develop

np

so, If I need anything, should I contact you?

How did you come across the project Frosty?

Bertl has a continuous charge time of 15 hours.

And fast charge 3 hour nap time.

you can also tell by my nick if I'm at a computer or asleep

Okay

cya!

u2!

welcome Dan3!

Hi Bertl

Question regardig the camera and logging in, or activating. I can log in fine but I am having trouble getting the blue light flashing indicating all is working. The camera is on, I can talk to it via Terminal but no live pictures. Tried a few things but now stuck, any advise please?

HDMI out into Blackmagic SDI convertor to an small Astro waveform which has worked fine many times this way, plus a new Blackmagic monitor with HDMI in directly. Neither seeing anything at the moment.

did you start the camera?

Yes I can access root and do some basic commans such as ./kick_manual.sh and reboot but I can't get to actual live camera mode as yet

that also means that live view is working

I am in root@beta

ok

(e.g. to a pastebin)

you might want to use minicom, if not already doing so, that has a 'log' feature

i.e. you can enable logging to a file and then upload that, or you can interrupt live console output and scroll back in history

sounds complicated :)

iTerm it is called

Camera is powered and working I have 1 x green light on and 1 x red light flashing bottom left if looking from the rear.

Yes it was working beofre and I recorded the HDMI output for testing so video was all good.

okay, let's run 'systemctl status cmv12k' then and see what it outputs

Loaded: loaded (/etc/systemd/system/cmv12k.service; disabled; vendor preset:

lines 1-3/3 (END)

sorry pastebin better new one above

./kick_manual.sh now and upload the output

I am stuck at lines 1-3/3 (END) window is locked can I restart via the top button or exit terminal to come back in?

hmm, why reboot?

Actually it is looping will cut and send what it has ouput so far

https://pastebin.com/F1ffu8n9

Ah :-(

ok

make sure that there are no extra forces on those PCBs, like from a lens system, etc

ok done a little bit I have a lens connected a Samyang EF version thats it

yeah, what about it?

no, that should be fine, unless you want to pull out the sensor (which I won't suggest)

okay, power the camera again, logon and run the kick_manual.sh

running now

https://pastebin.com/quGXHpHD

:-)

so it is definitely a connection problem

checking that they are connected properly and no unwanted forces are applied

Just jiggle them whil they are srewed together or loosen the bolts a little and jiggle a bit more

and if it fails, losen the bolts and jiggle a bit more

and the most common cause being a heave lens system without support

Thanks having a go now and once you remove the bottom tripod mount the whole rig loosens up, will try it a bit and loosen more see what happens, first go nothing trying agian now

i.e. just with serial console or ethernet and power

removed the HDMI also trying a kick.sh now. thats the question once that blue ligh it on that shows the comms is back as such?

Front housing section off now as well doesn't seem to connect to anything. Quite easy to do the front boards they pop out and back in again.

Do all five just slide apart

excellent!

sorry the kick manual reloaded and then stopped at the login then blue light came on rebuilding unit now

just repeated and the blue light came on during the new boot sequence after kick manual command line entered.

Blue light HDMI output is showing a flickering screen now so something is being outputted. Will try to set the correct output next.

the blinking rate is the framerate

The screen is showing just random bright blocks there is no live actual image just rubbish electronic flickering. Looking at the HDMI settimgs

how's the screen connected to the camera?

we haven't implemented pink noise yet :)

It is all wacky mode now but a signal though :-)

no, I don't _see_ it, maybe you can record a few frames and upload somewhere?

Yes thats what it looks like sebix good shout, thanks.

if it says YCrCb, then something is wrong

then happens what?

fixed pattern noise reeally but green with magenta speckles

and more importantly, did it work before?

Live images lasts for about 10 seconds same nosie image, Axiom B logo can be seen bottom left.

Other HDMI I have doesnt work at all so will try another newer HDMI cable in case this is the weak link

please elaborate on the setup and involved devices

Aye a picture of the set-up might be important.

how's that?

yes, that is a good idea, but <50Hz might be a problem for a PC monitor

had the same issue 1/2 year ago

This has worked before and I used the SDI convertor to record 1080P30 rushes last year so I know it is all good in that respect

so how does the PC monitor do?

for the monitor you probably need to switch to 1080p50 or p60

Put the UV filter on all is fine. Thanks all I will now tinker with the BM SDI unit so I can record some images for tomorrows testing shoot, with Tesla EVs :-)

well who knows just plugged the BM box SDI convertor in and it is fine?

excellent!

you too

Hello

https://www.dropbox.com/sh/fhsyagz98n97f3r/AACmHq4y_5UbLVPgxCJH54Aha?dl=0

have you compared normal and cooled picture?

and than I cooled the sensor

The difference was visible *

*photos

Interesting experiment.At least I can let the camera in refrigerator for 15 minutes and than take a rapid shot

at least one whichhas a freezer

also interesting -> http://www.hamamatsu.com/jp/en/technology/innovation/imaging/index.html

That s really cool. I have been a member of a NGO (http://vanguard-technology.org/members) focused on rocket building for 3 years . We also wanted to build a rocket tracker in order to track our launched rockets

like the old saying (which i'm forgetting to follow myself ;) ): don't chase two hares at once

*neighbour

Oh...that's cool. Which country?

moldova, but i'm not moldavian

And do you speak Romanian?

I understand. Anyway, very unexpected thing. When you told me you were born near Romania remembered me how small the world is.

still wondering how the cameras survive the hit on the ground, watched the ICARUS video

Yes. That was quite fun. We also wanted to experiment liquid fuel, but we encountered some problems in finding the proper fuel pomp and oxidizer pump

The Icarus camera didn't have a direct impact

It is not about the efficiency, it's about the time spent in air

not only that -> http://howthingsfly.si.edu/ask-an-explainer/what’s-difference-between-liquid-and-solid-fuel-rockets

liquid can be controlled

Yes, of course. This is another huge advantage. Liquid is controlled by controlling the pump debit

seems like the patent is older than we are :)

This was also a motivation

this is a good thing to have motivation

Yes, it is. That is why my main activities during faculty were student competitions. Winning awards and learn new things at those was a very good motivation. In addition, I am very glad I am not as foreign as I thought. (other people from Romania or surroundings here)

Thank you! Good bye!
