Great idea! I'm sure you could also 3D print something sturdy enough too with a good design. Perhaps PETG?

Yes I could.
If I had a 3D printer.
(next toy - maybe)

Here are 2 trigger cables I made.
The one on the left uses a snow shovel handle for the grip & a mini push button I had lying around.  The other one uses a stick handle with a mini limit switch leftover from another project for the trigger.  In both cases I used flexible speaker wire & BNC to Screw Terminal connectors I got from Amazon.
Both work fine but I like the feel of the limit switch better since it has a noticeable click when depressed.

... could you please explain what this sort of grip is for?

I'm playing with recording birds around our feeders, sometimes without a tripod. When the camera is hand held & I'm changing settings or adjusting the lens etc I find it awkward to hold the camera securely with one hand so I thought I would try this.  It does feel more secure to me but I've noticed, as I mentioned above that it is a little front heavy.  Once I find a more ergonomic stick, version 2.0 will move the mount point closer to my wrist.

I was looking for a pistol grip for my 1.4 but the ones I saw on Amazon all have a mounting screw that is too short (the female thread is the bottom of the camera case is a bit recessed) so I made my own.
I started with a small maple branch that felt good in my hand & cut it to size. The mounting screw is made of an old plastic knob with a piece of 1/4" bolt epoxied into it. Sanded then finished with tung oil.
High tech meets low tech.
Its a bit front heavy so I'll keep my eye open for a more suitably shaped branch when I'm cutting firewood this summer.

It doesn't explain, why the last segment is double the frames.

I think I have an explanation:
When I did the test, the camera was sitting on my desk & I rotated it after each trigger so that I could see the beginning & end of each segment on playback.  After I triggered the last segment, I didn't change the camera position. As foobar noted above, the camera would immediately start recording the next segment, overwriting the first.  Since I hadn't changed the camera position, the overwritten 1st segment looked the same as the last segment on playback.  I thought it was a double length segment whereas it was really 2 segments of the same still scene.

But, we do want to add an option to disable the ring buffer.

Good idea

One more thing regarding Segmented & Gated Burst recording - a software wish list item:
I'm not sure there is enough display real estate but it would be handy to see how much memory has been used in each of these modes. 
In Segmented mode "used of total Segments"
In Gated Burst mode "pct% used" or "seconds used of total Seconds" or a full/empty type gauge.

I would be willing to give up a bit of image space on the display for this feature.

Aha!!
I hadn't thought of that.  Thanks - very good explanation.
I've been playing with gated burst which may actually be better for what I'm trying to do.

What if you press the trigger 1 less time than the number of segments?  ...
...  Also, how are you checking where each segment ends? The Text Overlay on the save settings window gives useful data about current and total number of segments and frame within the current segment, so it is probably the best way to check.

Using 1 less segment is the way I've been using this mode.  I've been recording birds landing & taking off at our feeder. I make a mental note if the first segment I record looks expendable then I can make a decision whether to use the final segment if something better happens, not worrying that the first segment will be overwritten.  I find this mode of operation good in this instance because although I have a remote trigger I still have to go to the camera to save when the segments are used up & it takes a while for the birds to come back.

I check the segments on the Play screen & the number of frames match my settings (except for the last segment).

Does your camera behave the same way in Segmented mode?  If so, that would point to the software which I assume would be fixed in future and then I can stop spending time trying to figure this out.

I tried reducing the frames for each segment with no change in the result.
Resolution 1280/720 - total 12421 frames, 4140 each of 3 segments
I first dropped 30 frames - same problem
Then I dropped more & more ending with 12000 frames, 4000 each segment - same problem:  The second segment records 4000 frames, the third segment records 8000 & the first segment is missing, I assume overwritten by the second half of the third frame.

Subtracting 8-10 frames from the length of each buffer may fix this wraparound issue.  So, with 4 segments, you might try subtracting about 64 to 80 frames from the total Record Length.

Thanks I will try that when I get the camera back. (It's in the mail)

One other note about the batteries.
The battery / connecting prongs in the camera have some interference.  You can see in the photo where bits of plastic have sheared off where the little sockets plug into the prongs.  I've had to pick out bits of plastic from the battery sockets. I got a spare battery from Amazon which is identical to the one that shipped with the camera & both batteries are affected.

Update:
The battery now charges in the camera but my battery message does not always work.  Whenever the power cord is attached the battery status & voltage are displayed.  When the power cord is disconnected, sometimes the battery info correctly displays, other times the "No Batt" message appears, even though the camera continues to operate on the battery. See attached photos

I have v0.3.1
Resolution: 1280x1024 1057 fps
I select 4 segments, 2183 frames each.  Pretrigger 1490, post trigger 693 (behaviour is the same for several different trigger delays I tried)

Started recording & triggered 4 times.
2nd segment is frames 1-2183
3rd segment is frames 2184-4366
4th segment is frames 4367-8732
1st segment is lost - appears to have been overwritten by 4th segment which is twice as long as it should be.

I am having a problem with Segmented recording. 
Segmented recording always results in 1 less than the number of segments I  set.  The last segment is twice as long as the rest, wraps around the buffer & erases the first segment.
Sounds like a software problem.  Anyone else experiencing this?
