How does the ethernet function work? Is there any specifications?

That's currently in development, targeting release around end of January. When we have a detailed spec, there will be on this forum.

Software Dev / Software V0.3 Beta - Updated May 3 2018

« on: December 15, 2017, 12:52:17 AM »

UPDATE: V0.3 RC1 is out, go see the new topic.

We're just about finished testing the next software release, here is a beta you can try out. Try it out and let us know if you find any bugs.

You can downgrade to previous versions if there is a problem with this version. Just install the old version as normal.

V0.2.5 Beta Changelog (from V0.2:

• Settings are now remembered across power cycles
• Fixed issue where slow storage device would cause dropped frames. Video is now throttled as needed to prevent dropped frames on save.
• Increased the speed of saving H264, now saves at up to 200fps depending on resolution
• Added trigger delay setting screen (accessible from Record Settings), which allows setting of trigger delay with slider and delay in percentage, seconds
• Added support for gated burst and segmented memory record modes
• Fixed bug with RAM controller where horizontal colored speckling may occur when camera is cold
• Added support for all memory permutations (8/16GB sticks) across both DDR3 slots. Max memory is now 32GB
• Added save fps display to playback window
• Added "Delete all user calibrations" button under Factory tab (accessible for users)
• Camera now checks that storage device has sufficient free space before starting save
• Added RAW saving (Raw binary, 12-bit packed, 16-bit unpacked LSB and MSB aligned. DNG is still in progress)
• Added mode to automatically start recording on power-up and after save is complete (see Util menu)
• Added mode to automatically save video after trigger is received. (see Util menu) Together with above, the camera can run completely standalone without an operator
• Improved boot time
• Kernel - turned off USB gadget debug
• Filesystem - USB gadget networking update and boot splash screen added for serial numbers 00000-00049
• Partial Ethernet - requires commandline access to enable (ifup eth0) (NOT SECURE! DO NOT PUT THE CAMERA ON A PUBLIC NETWORK - Behind router/firewall should be OK)
• Fixed bug in V0.2.3 Beta where camera would claim there was no free space when there clearly is enough

Installation instructions:

• Unzip the Zip file into the root directory of a FAT32 formatted USB stick
• This should result in a camUpdate folder in the root directory of the stick
• Boot up the camera and insert the USB stick
• Backup your calibration data. Tap "Backup calibration data" and wait for this to complete (about 5 seconds). The cal data is now backed up on the USB drive as cal_[serial number].tar
• To install the update, tap Apply Software Update
• A message box should pop up indicating the software update was found. Tap Yes to install the update.
• The screen will go black, you may see a screen saying "updating", and the update will be installed. This will take about 30 seconds, potentially longer depending on the speed of the USB drive. There's no feedback that anything is happening, just give it time. The camera will restart at the end of this process
• Done!

I made sure to keep the answer to everything to myself, hehe. I have 00042.

A certain space related company got 00321, and a nice signed letter from all the staff thanking them for inspiring all of us.

00009 is on my desk, being used for software development and testing.

We haven't made 00666 yet, who should that be reserved for?

At long last, the Chronos Camera application source is now available at the following git repository:

chronos-cam-app

Currently we only support Ubuntu 16.04 LTS as a build environment. 17.04 is known to NOT work due to different compiler versions included. You're welcome to try other environments, please let us know what works and what doesn't.

Follow the instructions in the repository readme to set up your build environment.

We suggest not doing any significant changes or customization right now. We are in the process of breaking out the low level camera control into a daemon controlled over D-Bus. This will allow the cam app to talk to the camera seamlessly, whether local or operating remotely over a network connection. Ideally, the exact same application will be able to be compiled to run on the camera or on a PC.

Once you have the application compiling, you can connect to your camera over SSH. Plug the mini-USB port into your computer, and it will enumerate as a USB to Ethernet bridge (serial numbers 00050 and above, earlier cameras need an update, available here). You can then log into the camera using root/<no password>

I'm sure there will be many questions, please let us know any problems so we can provide better build instructions.

Software Dev / Re: Has this image issue been reported?

« on: November 20, 2017, 06:15:51 PM »

Hi John,

The horizontal lines in the first picture are a known issue, as you said, black cal will remove them. It's in the pipeline to add correction for those so you don't need a black cal every time, but many other features are higher priority.

The dead pixels you're seeing appear to actually be on the image sensor. If you're OK waiting, we're going to add dead pixel correction, if they're really getting in the way right now you could send the camera back and we'll replace the image sensor at no charge.

The colored dots/bands are the RAM temperature issue, the new update coming in about a week will completely fix those.

Software Dev / Re: White screen when trying to save clip

« on: November 18, 2017, 09:31:20 AM »

Great that tightening the nut fixed it! Nothing is damaged by the lose nut, it just causes a reset when pressed in.

You can try recovering the files with the utility recover_mp4. This utility is a little complex but works very well.

Hi John, try pressing the jog wheel when the camera is in recording mode. Does the white screen still happen? We had a couple of cases where the nut under the knob wasn't tightened properly and tbe camera would crash when the wheel was pressed.

Software Dev / Re: Problems updating

« on: November 17, 2017, 06:43:04 PM »

David.

The usb does show up in the playback. But to able to see the settings screen in playback i first need to record footage before it will un-gray the button.
But still no joy in preforming a backup or update. Just error.

One other strange thing I came across
After recording a clip. If i go to record over it again and not save it. I get the screen asking if I want to delete it.
I tap the yes button and it just sits there stuck on that screen. Nothing happens yes or no does nothing. Some times it will work but for the most part a hard boot must be preformed.

If the USB shows up in Playback the drive is working. Could you show what's on the root directory of the flash drive? You need to extract the update zip, this should result in a camUpdate folder on the root of the drive.

We've been able to duplicate this on our end too. Looking into what's causing it.

It seems the USB device is not being recognized. You must use the full size USB port (eSATA/USB combo port). Go to the Playback screen, then to Settings, this screen has a list of storage devices that will show any valid drives that are attached. It updates every few seconds, so give it some time after plugging in the drive. If your drive is not showing up in this list, something is wrong. Have you tried other USB drives from different manufacturers?

The camera does not currently work with exFAT, you need to use FAT32 formatting.

Chronos User Discussion / Re: Adapting other lenses to C-mount

« on: November 11, 2017, 11:33:47 AM »

After a short search I found the opposite, a C to E adapter:

https://www.amazon.ca/Fotodiox-Adapter-C-Mount-mount-Mirrorless/dp/B003Y32238

This leads me to believe it's not possible to make an E to C adapter, the flange focal distance of E mount lenses is too small for this to be physically possible. An E to CS adapter may be possible, but I don't see anyone making that.
