I managed to damage the reset button seal on the new camera while trying out a stainless steel grub screw. I'm glad I did, it forced me to take the Sika 291 back off and dismantle the camera partially.
The worrysome weak spot of the reset-button seal is now fixed semi-permanently, with a stainless steel grub screw and Sika291 between the grub screw and the thread in the camera housing. I sanded the top of the grub screw nearly flat, so that if it gets screwed in further, it will touch the reset button before touching the soldering connections for the reset button.
If for some reason it becomes necessary to push the reset button, then I can screw this grub screw in a little further to do that, but it will probably break the seal and cause a lot of work in order to de-seal and re-seal it.
The Sika 291 came off fairly cleanly from the camera housing, but not without significant effort; and the latex shields worked very well on the screw heads. In an emergency (i.e. water in the camera), I could open the camera up within a couple of minutes if I have the tools at hand.
I put a bit of Deoxit Gold G100L on the smaller circuit board while the camera is open. I did not take the rest apart to get to the second PCB, and I'm not sure what deoxit would do to optics if it got to them, so I only put a little bit on the smaller PCB that is furthest from the lens end of the camera.
Voilà : The first really waterproof 360fly camera!
Not one bubble emanating when recording under 45C hot water.
Congraulations on mission accomplished.
I am Looking forward to studying more of the video, and seeing Kirra's bottom go by as the fin flexes.
Wish I had your water clarity.
I decided to drill a hole through the lid, so that I can see the LEDs indicating if the waterproof 360fly 4K is still recording.
It might also serve as a water pressure relief mechanism, in case high water pressure is created under the board and into the camera housing during surfing or jet-ski tow experiments.
The first test with the waterproofed 360fly 4k (Fineye2) went relatively well.
It did not take in any water, the main concern, but it malfunctioned somehow and did not save the recording of the only nice wave I caught. The video file is unreadable.
The camera did appear to be working, and I was able to see the red recording LED through the hole in the camera srew-lid-holdermagigg while I was in the water, but when I unscrewed the camera in the shallows, I found that the LED had turned blue (= standby) instead of still recording. The camera did not start to record when the button was pressed, the software was 'hanging' in one way or another. I was able to turn it off with the button, restart it and then record the trip back to the car park. That part recorded as expected and the video file is not corrupted.
1) Set camera to record 4minute segments automatically. Hopefully that means that the recordings already saved will be OK, even if the same malfunction recurs. With 4 min segments set, if the red LED is visible more than 4 min after a wave was surfed, then the recording is going to be valid. If everything is recorded as one file, then it could get ruined later on.
2) Check if the red LED is still 'On' before unscrewing the camera from the housing, in case this is something that happens during unscrewing, somehow.
So unfortunately, no footage from FinEye2 yet. It's a shame because I had not sanded the G-Whale-7-SL fin well enough and it was making whining noises during the one wave. It could have been useful to see and hear the footage of such an event.
Unfortunately the reset button appears to be necessary, more so with the replacement 360fly than the first one.
While trying to figure out setting changes, made via Blutooth and WiFi connection between phoneand camera, and transferring recorded files to PC via USB cable, the camera had a hissi fit and stopped responding to any input via the single button. I left it on overnight, but the LEDs were still on the next morning, still cool to touch, still unresponsive. So I had to break the seal of the semi-permanently sealed reset button by screwing in the grub screw until the reset button activated. That worked well, no surprises, but the seal needs to be redone.
I don't want to take the camera apart to reseal the reset button hole, because I have a great seal all around the camera now, so I devised a method to seal the grub screw in the reset button hole from the outside.
Procedure to re-seal the 360fly 4K reset button with grub screw:
(This only works after the camera has been dismantled once before, and the original reset button seal has been removed, and with a grub screw with rounded convex tip, see earlier post for details.)
- Screw grub screw in very slowly until reset button activates. Turn 1/6th of a turn or less at a time and wait 6 seconds minimum between incremental turns, because it takes that long for the reset button to register that it is being pushed.
- Unscrew 1/6th turn from reset button activation depth.
- Use tooth pick to work Sika 291 into corner of screw and nut interface, and the into windings above the grub screw
- Unscrew grub screw by one full turn with Allen key.
- Clean out the excess Sika 291
- Let set
- Seal test.
The grub screw outer edge is 5.2mm deep when just 1/6th turn (= 1 corner on Allen key) from activating the reset button
Screwing it out by 360deg (6 Allen key corners) results in 4.0mm depth
The screw on camera holder has sufficient 'grip' when it is 3.5mm long, so it will fit together.
I'll let you know how the sealing test goes.....
I'm getting some amazing footage with the 'FinEye' camera.
Crystal clear, glassy Kirra waves allow to see the waters action on the sand.
Even my shadow can be seen surfing the wave.
Hope you can make some sense from the still-image.
Have you learned anything from what you've been seeing?
No; It's not an ironing board.
Have you learned anything from what you've been seeing?
I'm certain I have learned something, but what exactly eludes me so far. HAHA!
Below is a link to a 3D video of one of the waves in 'FinEye' footage. It's a 33.8MB download. A recent version of VLC can play it and you can zoom in and out and look in any direction.
See if you can figure out what is going on.
It seems to me that the fin sometimes bends in the opposite direction of what I would expect.
The fin is the G-Whale-7-FLT (7 tubercles, Flanged, Lean thickness, Tunable flex pattern).
