Good morning everyone, This project concerns the realization of a system to hold a mobile phone with one arm, facilitating the use of complex functions.

I will show you immediately the object I have created, below you can see the use of the bracelet, with the mobile phone position horizontal and vertical.

The project was designed to facilitate the use of some particular gimbals for my video needs, then I realized that it could be useful in a thousand other situations, for example a DJ who wanted to mix with one hand, or even simply those who have to do mathematical calculations with one hand, there are a lot of applications.

The first prototype had a straight arm and a very thick bracelet, it was extremely uncomfortable to wear and could not be used due to the limited space.

New prototype with curved arm

The new prototype with curved arm is much more functional, it is still far from being comfortable, but it is usable, the curved arm allows you to use the phone in an upright position.

Arm length is adjustable and and settable using a pin, on the upper part of the bracelet there is a Velcro strip that allows a better hold.

Prototype 2 is still far from being comfortable, but it has made significant progress compared to the first!
