Why do you need yet larger super capacitors? or am I misunderstanding something?I keep hoping for that. Because the circuit board would be exactly the same, the only change would be the case and maybe they would only have to change the bottom part of the case to fit the larger super capacitors in. Depending on the size of the super capacitors they chose, the increase would only make the Mobius maybe 10mm (0.4 inches) thicker or less.
It could be marketed as the Mobius DC Edition....
DC = Dash Cam
I think the capacitors need to be mounted transversed compared to your picture. In this way that orange cover must to cover just the capacitors, no more.
Also I expect they will use some thermal cover to mold around the capacitors.
Just make a test with them transversed compared to the battery, because in other way the capacitor will press on the CMOS cable.
My camera is working almost OK also with the actual firmware and the capacitors.
Regardless of what heat they generate if the the Mobius goes into thermal protection at 47c its going to cut off sooner than the 0801 that thermals at 70c
Whilst that is true, waaaaay back when I did physics, we were also taught that black was a better colour to wear in the summer since - your body temp will be higher than that of the air. Slightly looser clothing will absorb this excess heat & 'lose' it to your surroundings as the clothing is blown around. As white reflects, not only does it reflect much of the heat from outside away from your body, but everything your body is trying to lose is also being reflected back at your body!
We even performed experiments with different coloured cloth on a light bulb to test this theory
the problems it has are firmware related but not heat related, was just referring to the thermal properties of the respective hardwareThe 0801's claimed thermal tolerance is academic, unless it's seemingly never-ending firmware problems get resolved.

I all depends on how and where to mount. If the way you or me like to mount ( most discrete way ), then yes, - no sun reaches it, especially if car windshield has sun-strip. Some cars dont have sun-strips, or owners dont have DIY skills to make special bracket / mount, or some drivers like to install directly on dash. Different people, - different ways to mount.
I was start thinking, -would it be bad idea if whole body of Mobius would be made of mesh-steel / aluminium ?
Yes, it will probably add on some weight, but dont that dramatically, - aluminium is fairly light material.
Having mesh-aluminium body provides very good cooling for internal components. As long as heat inside is higher than outside, - it will be always instantly escaping via mesh.
I'm losing track of where I've posted! On another mobius thread I said something along the lines - If the only problem with the mobius is that of heat generated in such a tiny space (problems from making everything so tiny then cramming it into the smallest of spaces), why not simply use a remote lens (AFAIK, there is a lens on a short cable (8"?) for the mobius).
Put all the internals into a decent sized box with plenty of vents, maybe add a decent heatsink to one face, maybe add a small fan, keep the battery well away from the main board (or bigger box, bigger capacitor) ...
If we can mount the body well away from the lens then the size and cosmetic appearance of the case isn't an issue.
So it's not like we're asking the manufacturer to come up with anything drastically new & inventive - simply take an existing good product & adapt it for the car market.
If some manufacturers are looking at 360deg coverage, why not put 4 mobius boards into a large case, decent fan, decent capacitor, 4 remote lenses - presto, 360 deg coverage & great cam setup. If the mobius can be linked to smartphone, tablet, laptop etc, software on an app could be used to sync the timestamp of all the cams & even be used to drag files off.
