good day

Time is irrelevant with my level of dedication

Keep on clocking in the reee world

Hey Herbert! Everything is setup for the test. Would you be available around 13pm ?

*parsing

now :)

*equipment

and ceramic screw driver

good, got the cables to connect it?

maybe take a quick snapshot what you've got and upload it to imgur.com or so

do you want to work with webcam?

photos are sent through mail

ok

have you got some connetors to probe the headers?

*connectors

what do you call header

?

okay, check out this (old) power board, you see the eight holes in each corner

https://imgur.com/a/FjvP0Ta

you need to probe through two of those holes into the power board headers

for that you need something like the golden pins on the interface board

you want to probe the leftmost pair on the top right header

ok the pair is one "hole" from the top line and one from the bottom line ? (still the leftmost)

be careful that the 'cables' or whatever you stick in there do not go too far in

as I said, a typical 2.54mm header would be best

the first step is to limit your bench top power supply to 3A and set it to 5V

compar that with the reading from ./pac1720_info.sh

5V 492mA on benctop

good that looks perfect

./power_init.sh

./power_on.sh

also measure the output of the pin header pair with the multimeter

494mA on benchtop

do you happen to have an electronic load at hand as well?

what do you means ?

no, what I mean is to put some stress (i.e. draw some power) from the rail

in any case, we can do without, but it might provide some insight

well, as I said, one option is to use an electronic load

anyway, if you do not have any of those at hand, let's just re-adjust the rail and see how that goes with the stack

let's jump on the next option because we don't have extra electronic load at hand

when you turn the trimmer, the voltage on the rail will start changing (multimeter)

you also want to turn it one complete 360° turn around to make sure the electric contact ist good

then try to adjust it as good as possible to 1.9V again

TR3

the one I marked on the picture (TR3 :)

360°

now 2,2v

starting position 1,8v, then 90° 1,6v, then 90° 3v, the 180° initial position 2,2v

that is unusual and might point towards a defective sensor

it can be tricky as the range is quite small

ok, back to 1,9

that's always tricky

if yes, i would test with another one

ok

okay, let's put the stack back together and see what we get

double check that the interface board is facing up (i.e. the arrows point towards the top of the camera)

yes, including the sensor, let's see what we get on the power rail

ok, everything is back together and the power is on

./power_init.sh

./power_on.sh

./pac1720_info.sh

https://pastebin.com/LLVwHzTA

so the LVDS voltage looks fine now

good news already

sleep 5

https://pastebin.com/yU5tWkgA

(sensor normally hot for now)

what's the return value you get?

too bad, would have been nice

yes...

https://pastebin.com/XweTQHaJ

./kick_manual.sh

yeah, that's fine

you need to add your ssh key to the Beta to logon via ssh

https://wiki.apertus.org/index.php/AXIOM_Beta/Manual

the ./kick_manual.sh does the same as before

that is unusual, but check the authorized_key file

can you pastebin part of the loop for me?

yes still zero

but it might be easier to send us the camera including sensor for general testing, as we have all the equippment needed including loopback adapters

we also can test the sensor in a known working stak and the stack with a known good sensor

for the loop

okay, let me know what you decide, and when you go for shipping it, let me know so that I can give you my address to speed up things

okay, I send you my postal address via email then

(the sensor was really hot at the end)

okay

you're welcome!

Bye !

Hello @Bertl

how are you?

hey rahul_!

hi AbsentFilms_

i again started looking into the placement of my peaking IP

sounds good, Bertl_oO sounds like your man for this

rahul_: you meant you want to discuss it now didnt you?

but i am not able to pm either @sabestian or @Bertl

thats because your nickname isnt registred with freenode I assume and they stepped up measurements after the recent spam waves

or register your nick

ok
