I've built my Mobius Maxi inside of my car's rain sensor & GPS cover. I never liked the look of a dashcam on my windscreen, and there was ample space available in the cover, so this is the result:
The lens itself sticks out slightly below the black coating on the windscreen - you can just about see it if you zoom in on the third picture.
The internals looks like so:
What I have done is taken the main board out of its case and stuck it to a piece of plastic (G10) using some Sugru (mouldable silicone). I then stuck some 3M "Dual Lock" to the plastic and the cover so that I can remove it if required (there is nothing I need access to on the back of the PCB). I then soldered 3 buttons to the legs on the PCB and mounted them further up on the GPS cover. The capacitor conveniently fits in the indentation designed to surround the rear view mirror - this is also Dual Locked to the cover. The lens itself is is also kept in place with Sugru. The rectangular module with blue connector is my car's GPS antenna, that's Dual Locked on as well. Power is tapped from the dome lights by soldering onto the terminals, and the USB out is fed through the headlining.
I got a large heatsink out of an old BT hub and cut it to size. Conveniently, the mounting holes for it were the perfect size for my 1mm optical fibre strand. I cut the heatsink so that the optical fibre hovers
just above the 4 LEDs. I then drilled a hole just big enough to poke the other end of the fibre through. This allows me to see the status LEDs from inside the car - and it dims the light a little as well, bonus! It is the one thing about this "project" that actually worked surprisingly well. You can see the Maxi is in mode 2 in this picture pretty well on a sunny afternoon:
Lastly you will see I cut a shape out of the top of the GPS cover. This was to place a SD card extender so I could access my files without taking the cover off. I'm still working on this at the moment.
The lens is aimed well and there is no vibration visible despite my harsh suspension (Fiesta ST). Reflections are not any better compared to a regular suction mount, even when so close to the glass - perhaps soon I'll try and make a CPL for it.
Very happy with the results so far. In hindsight, I wish I had searched a bit longer for smaller and more subtle buttons - rather than taking what I had lying around. I also wish I had a higher quality 12V -> 5V converter, as this one seems to mess with my DAB reception, but only if the wires run parallel with the DAB antenna. I've just stuffed them in opposite corners and this seems to solve the problem.
