Project - ST Tracker
Main menu:
Aims:
The aim of the project is to create a device capable of keeping track of the time spent in the various daily activities. The device consists of eight triangular faces to which the various activities have been assigned. The data acquired by the device are available to the user through an appropriate connection with a PC or mobile devices.
Design choices:
After an analysis of the specifications and the available materials, we chose to use a single board computer with an operating system based on Linux kernel (RaspberryPi 3A +). This board allowed the connection of a three-axis gyroscope, controlled with a Python code. A LAMP platform has been configured to store the acquired data in a database and host a web application that allows the devices connected to the WiFi to display the data. In this way there are no restrictions for the types of terminals and operating systems used. The system has been equipped with a battery to power the board and an RTC module to keep the date and time data always up to date. To simplify the realization of the prototype, the octahedron that contains the entire system was built in Plexiglass.
