Software Dev / Re: Very ugly artifacts after upgrade to 0.2.5
« on: January 09, 2018, 07:59:22 AM »
I did buy these modules: https://www.amazon.de/Komputerbay-Channel-DDR3-1600-SO-DIMM-PC3-12800/dp/B01LFQH95Q/
Also I (obviously) used only the new RAM since the factory one is most likely faulty.
Generally mixing different RAM vendors / capacities / speeds works, but will not lead to the best results. And if the RAM is accessed in dual channel mode, both modules have to be the same latency/capacity and so on, but different vendors might be ok. I don't know whether Chronos uses dual channel mode.

The default RAM has no markings which lead me to a manufacturer of it, but if you really want to I can send you a picture of it. Or the devs tell you which one it is ;)

I exchanged the RAM for two new 16GB modules and the error appears to be gone!

I did everything as described, my camera is back to 0.1 now. The error is still exactly the same  :(

Ok, mail is sent. However I'd like to try a re-flash of the OS SD (to any version, but preferably 0.2) beforehand. You mentioned this possibility in another thread but I can't find a complete download.

EDIT:
Also I noticed that it takes a short moment before the error appears after triggering, so maybe the RAM is faulty? I'm going to record a video of my Chronos so you can examine it better later today.

Here's one raw frame if it helps

UPDATE:
Ok now I'm really worried: I reverted back to 0.2 (which only took a few seconds which is odd) and the error persists, but the pattern is slightly different and changes during the recording. I had no issues before I started playing around with the updates, and I did't do silly things like droping the camera... But it now feels like a hardware issue.

The install of 0.2.3 failed without error and i was still on 0.2 (at least that's what was displayed) so I can't tell if it's a new error.
I now tried rebooting: The camera works fine again until you start recording, then the artifacts appear again and are also in the saved files.
Black calibration gets rid of them until you start another recording.

I just noticed: At about 38sec in the video the appearance of the "errorbars" changes. This is no youtube error, it's actually in the file.

Software Dev / Very ugly artifacts after upgrade to 0.2.5

Hey Guys!

As mentioned in 0.3 Beta release thread, I could now update my camera.
I just tried a very basic shot just outside my window (cloudy, overcast, not really lit at all). The image looked fine on the screen before I started recording.
As soon as I pressed the trigger, very ugly vertical stripes arranged to form many horizontal stripes in total appeared on the screen and are now persisting in the preview mode.
The recording also has these artifacts, see the attached screenshot. These are so bad that they basically render the camera useless.
However I haven't tried anything to remove these yet (no reboot, black calibration, etc) to give you as many info as possible while the error persist.

Also I took a photo from the image displayed on the cam with its lens cap on, also see attachments.
The saved erroneous video is here: https://youtu.be/-_Sd_xi1CpU
I also saved the raw 16 bit output video, if it might be useful I can also provide it.

Software Dev / Re: Saving setting across reboots is BAD

How about some (configurable) presets? Perhaps with 3-5 buttons or a dropdown for quick selection right on the front page?

With 0.2.5 I was now able to update my camera without issues. But I used a different USB stick, which might also have helped. On towards testing the new features ;D

You've probably already tried but did you try to reboot the camera?
yes, it had no effect. I'm still on the old version.

Software Dev / Speed boost to 38k fps?
« on: December 21, 2017, 01:57:59 PM »
Hey!
Is the speed boost already implemented as mentioned in the Kickstarter campain?
Quote from: Kickstarter
Chronos 1.4 is getting a speed boost to 38,565 fps at 336x96!
The default FPS options does not include these settings on my camera. I know somewhere in this forum it was mentioned that a file on the OS-SD card can be changed to include other options, but I cant find that post at the moment. Would my camera be able to record at 28k FPS if I were to change that file?

Hey!
I just tried to update my camera and it did not seem to work, however I'm not sure what failed. As far as I can tell I'm still on the old 0.2. Version because I cant find any of the new features and the version dialog still claims to be 0.2 (and not 0.2.3 or 0.3 or whatever)

The upgrade process itself went exactly like described in the first post, no errors appeared. I'm using an 8GB USBstick, maybe it's too big? But the update was recognized by the camera and it did find and apply the update on the stick.

I know this is a really bad "bug" report as it contains virtually no info, so please tell me what to try and which information you need so I can report back. If needed, i will record the whole upgrade process using another camera ;)
