Chronos User Discussion / Re: Upgrading the 1.4 to the 2.1
« on: August 05, 2021, 11:46:24 AM »
Its been two years since the original post so I guess its time to ask again, Is there any progress on upgrading the 1.4 to the 2.1?

Here is a video I made about my latest project that includes clips from the Chronos 1.4.  I mounted a Chronos in a rocket to capture some amazing footage.

The Chronos clips can be found at 00:05, 08:30 and 11:30 if you don't care to watch the rest of the video.

Any update?

I was wondering too.  I signed up for the newsletter and received a confirmation message but nothing since.  I have plans for a shoot later this year and it would be nice to know if the upgrade would be available, how long it takes, costs, etc.

We are working on a plan for trade-ins. Details are not ready just yet. You can sign up for the newsletter here so you will know when we do have details ready: https://mailchi.mp/krontech.ca/chronosnewsletter

done, thanks!

Chronos User Discussion / Upgrading the 1.4 to the 2.1
« on: September 17, 2019, 08:15:23 AM »

I heard there was a plan for the 1.4 camera owners to be able to upgrade their camera to the 2.1 by some sort of a trade in policy. Is there any progress on this or is it just a myth?  What is the time frame and how much will it cost?

Software Dev / Re: Can't fine the overlay feature
« on: November 27, 2018, 10:03:48 AM »
Thanks, I did get it to work.  However, after turning off the camera and back on and using the auto record and auto save feature, it did not add the overlay.  Is there any way to have the overlay automatically be on with the auto-record / auto save?

Software Dev / Can't fine the overlay feature
« on: November 25, 2018, 11:46:17 AM »

I've upgraded the firmware to v0.3.1 beta 9 but I cannot fine the overlay feature to add the time onto the video clip.  I did skip the previous beta 4 version, do I have to do the upgrades in a particular sequence?  Thanks,

Doug

Software Dev / Re: Remote power on

I'm not sure If I'm the only person but I expect that the camera might be used by more people where it can't be accessed easily and leaving it on 24/7 isn't an option.

Although I am not running the camera 24/7 I have used it running for >10 hours recording using an external power supply and just starting and stopping the recording via the trigger.  There were no issues using the camera this way and the environmental temperatures it was operating at exceeded 107F and the camera was enclosed in a box.  I did provide a opening that I could push the on/off button so I could turn it on in the morning and off in the evening.  Maybe this would work for you.

Chronos User Discussion / Protecting the Chronos
« on: July 03, 2018, 10:07:45 AM »
I use the Chronos cameras to record the liftoff of rockets so naturally the camera needs to be protected.  In one case the rocket passes just inches away from the camera so not only does the camera have to be protected from the heat and flame of the rocket motor but the protection must also allow for the camera to be cooled.   The camera must operate in environments that are dusty and at temperatures of 105F/40C for about 10 hours in the desert.

I used a Hammond enclosure 1590EE (https://www.digikey.com/product-detail/en/hammond-manufacturing/1590EE/HM441-ND/2627894) that happens to be the perfect size for the Chronos and the camera is mounted to the lid with 25mm standoffs.  To allow for cooling, I drilled holes in one end of the enclosure and used a regular dust mask as the inlet filter.  It tuns out that the paper filers could not withstand the differential pressure and blew out so I will have to change the filter material for the next launch.  I made an exhaust duct for the fan with a 3D printer and used penetrations in the cover that allowed for external power and the trigger signal.  Although the enclosure is not sealed, I did seal up the lens opening with Silicone glue to prevent the corrosive gasses from entering the camera.  The lens was protected with a UV filter and is cleaned between launches.

I was concerned about adequate cooling but the camera never overheated or failed to record the launches and the inside of the box remained clean.

What Lens do you have on the Chronos in that Picture?
Looks fairly wide to me, like around 8mm or 6mm or so?
Maybe Kowa?

Yes the lens in that image is the Kowa LM8XC.  I use a 5mm Kowa for the camera on top of the rail.

Great footage! Could you please post a picture of your pitching system? It sounds interesting!

http://www.rocketryphotography.com/_LWR0667.JPG

The mechanism is straightforward, a geared motor controlled by a Pololu Jrk21v3 motor controller with feedback (https://www.pololu.com/product/1392).  The feedback is provided by a potentiometer to provide position.  It is triggered via a switch at liftoff and uses a slight delay.  The other cameras in this particular set up are the Sony a6300 for stills and a Sony X1000.

Your footage is amazing! Did you follow the first rocket manually or do you have a jig with some kind of actuator that pans the camera?

Thanks, the cameras pitch automatically based on the rockets acceleration and liftoff is detected with a switch on the rail.

Here are two videos I took off of my set up filming rockets at the Spaceport Americas Cup.  This one pitches and follows the rocket and shoots at the default 1,057 fps.

https://vimeo.com/276555084

This fixed mount is located near the top of the rail and shoots around 2,000 fps.  I hope to post how this camera was protected in the near future.

I'm impressed with the performance of the CHronos cameras.  They ran about 10 hours in 107F/40C temperatures and had no difficulty with them at all.

Chronos User Discussion / Test Video issues
« on: June 10, 2018, 09:04:28 PM »

I ran a test video today with a custom resolution and frame rate (not built in).  During recording and on playback the video shows flashes of light like it did not record properly.  THey might be frames that were not recorded correctly.  Can anyone tell me how to prevent this?
