Since I got borrowed a Smartphone from Mapillary (more about that soon) but no mounts for car nor anything, I had to make up some.
As I needed one for the car I had nothing usable with me than an old T-Shirt which was dedicated for cleaning purposes.
I just ripped a strip from it – et violá:
lowest cost smartphone mount ever
A sequence recorded this way
A mount for walking was not as easy to create. I purchased what seemed to be a durable smartphone cover for about 8 EUR and a 30 cm long strip of 5 cm wide hook-and-loop fastener for ~1,50 EUR.
From hooks part of strip I cut two parts each as long as the smartphone cover was wide. Those I glued to the back of the smartphone.
The other half of the hooks strip I glued back to back to the loops strip.
So I had a wristband and was able to use the the smartphone as smartwatch with the biggest screen ever:
multi purpose scratchy wristband
Biggest and most inexpensive smartwatch ever
phone backside with hooks
(You should spare some loop strip to cover the hooks not covered by the mount. Else it could happen that the hooks stick now and then to the shirt you wear.)
But since I also want to use the smartphone with Mapillary while walking, I had to work a little more and punched some ugly holes into the side of the cover.
Now the phone could be put into the cover with the back to the front without the buttons being pushed all the time.
To use it while walking I put the hook-and-loop Band around the left shoulder strap of the backpack, let the Mapillary app record in walking mode, put it back-to-front into the cover and attach the latter to the hook-and-loop band (aka mount) at the shoulder strap.
Addendum: Maybe one should also consider to mount the camera at the shoulder strap a little more to the sternum and away from the arm since it seems I lifted it a little with the arm sometimes. I looking a bit knackered after walking some km with the stuff
