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.

Did some more fiddling with the the segmented memory mode and still had no luck. For the sake of having a small video file I set the record frame-rate to 30fps, set the "Record Lenght" to 300 frames and set 2 segments of 150 frames each. I filmed at timer and pressed the external trigger at 10s and 20s then stopped the recording at 30s. I added frame numbers to the result and made the following gif.



The recording ended up only being 157 frame long and contained mostly the video that occurred after the second external shutter press. Some of the jumpiness can also be seen. Any idea?

I was playing with the segmented memory mode and I'm not sure if I am using it wrong, my trigger switch is bad or I have a legitimate bug.

-I set to Segmented mode with 3 segments
-Start recording
-Press the external trigger after the events I want to catch
-Stop recording after triggering 3 times

The recording I get is mix of short and long out of order clips, some times from all 3 segments in rapid succession, sometimes from different places inside one segment. The total length seems to be correct and everything that I wanted to record seems to be there but I am not 100% sure. I might try recording a stop watch to see if it gets everything.

My trigger is not the greatest mechanical switch, but the results are the same with de-bounce both enabled and disabled. If this is a 'layer 8' problem please let me know, otherwise 0.2.5 has been working well for me. I installed another 16gb of ram and the camera sees and uses the new memory.

Installed the .5 update with no issues, last time it didn't seem to like my USB stick, this time everything worked on the first try. I have another 16gb of ram ready to install, hopefully I will be able to try it out later this week.

Thanks, David!

Also, the open source release is imminent, finally have a working build environment that doesn't have any of the NDA code in it! Hopefully within the week.

Awesome news! I'm really curious to take a look under the hood.
