That image is for the v0.1 software.

Every time updated my Chronos I would take out the OS SD card and make an .img file, that way I could always restore an image if I broke something. If you can't get your camera to update you could use one of my backup .img files, write it to a microsd card and put it in your camera, then you would have the up to date software. You would also have to restore your calibration data because my backups contain my calibration.

3
If you want I can send you an image of my updated SD card. You would need to restore your callibration data (mine is part of the SD image). It's ~700mb but I think Google drive will share stuff that big.

Are you using the same usb stick that you had for previous updates? I have found that only out of the pile I own will work for updates even though they all work for backing up callibration and saving video.

You guys are awesome for your continuing development work and I am super excited to hear that you picked Debian as your next os (completely unbiased Debian user here). I continue to flog the Chronos every chance I get to potential buyers.

It is really freakingly hard to film flying birds...

If you want to film birds I _really_ suggest getting a gun sight and mounting it on top of your Chronos. Before shooting you have to align it with some object at the same distance as you expect to be filming and then you are set. I have used it to get frame-filling video of birds in flight, taking off and landing.

I'm going to be at the Toronto Maker Festival this year so I have been compacting my demos for travel. I build a mini-ribbon speaker and it does some seriously weird stuff when over driven. The video shows both real time and Chrono-vision.

Awesome, updated just fine and all the features are there. Only weird thing I could see is under "About" it still says RC1, made me do a double take after the update. Thanks for features and fixes!

Another turkey vulture but this time saved in raw. Next step for sure is building a portable battery/psu so I can get an hour or two of recording and saving time.

Yeah, its a 400mm f6.3 non-telephoto lens. Being f6.3 makes it only good for very bright sunlight but it is not heavy compared to telephoto lenses so I always keep it in my kit.

having a gun sight on the camera makes following a target super easy!

Sounds very interesting. Can you show us what you made there?

The reflex sight is an Amazon special, not the cheapest one but it's not made for a real gun. To mount it I drilled a 1/4" hole in "gun rail" which is used for mounting hardware on to guns, and ground down a 1/4-20 screw to sit as flush as possible with the top of the rail. If the head sticks up too far the sight won't mount properly. There are kits that let you mount gun rail to a hot shoe (camera flash mount) and kits that let you mount a hot shoe to a 1/4-20 hole but the taller your mounting setup the more parallax error you will get and the less stable it will all be.

Every time I shoot the sight has to be adjusted, it moves a little while being transported but mostly it's to account for the range of distances I am shooting that day. By picking a spot midway through the field and centering on that it is pretty accurate as long as I remember to aim high for close subjects and low for distant ones. If you are going to film fast moving subjects it is worth the $30.

It was an overcast day and I forgot to do a black cal after the camera had warmed up but having a gun sight on the camera makes following a target super easy! Blue-jays, vultures and a coyote.

Just a quick question about the update process. If I made an image of my current OS microSD card could it be used to roll back from 0.3 if I ran into problems? I'd like to test out the new colour handling but would also like a safety net. If so I shouldn't need to reload the calibration data correct?

Just wanted to chime in about RAW workflow.

I am using a 128GB USB drive formatted to EXT3 to save files from the camera and avoid the 4GB limit of FAT32, this works perfectly. To get the raw files onto a windows PC I use the software "ext2explore," it's a little clunky but it will get the job done. The pyraw2dng also works perfectly, even with raw files that were broken by the FAT32 limit and my own clumsiness.

To convert the DNG files to 'normal' images I am using Rawtherapee, an image editor meant to be an alternative to Adobe Lightroom. Rawtherapee allows for batch processing of files, so I make my adjustments to one frame and apply them to the whole set, I've done about 8000frames in one go with no problem. Once I have a folder full of PNGs I assemble them into a video file using VirtualDub, this allows you to set the final frame-rate of the video and export it as a raw or compressed AVI file.

All the tools used are free (as in beer) software and the only real limiting factor for any step in the process is time and processing power.
