The primary motivation behind creating this device is to provide a lazy way to interact with Computer or android tv. The device is a enhanced version of the air mouse, usual design of the air mouse are more like a remote control, what I wanted to create is a small form factor and user experience like a vertical mouse with added media control keys.

The ESP reads the gyroscope values and maps them to cursor movement and keys to perform clicks and keystrokes, have added an encoder for volume control and a dedicated momentary slider switch for muting, a 5 position miniature joystick is used for horizontal/vertical scroll. The board also has an lithium charger and power converter for 3V3.

Every 15minutes the device will report the battery level.

Made a quick breadboard prototype to make sure the code is working before the PCB and components arrive.

I'm planning to use a prismatic pouch cell to power this, and the availability of these cells varies from place to place hence I have left the enclosure design open ended.
