For those of us who love cars either driving them or just riding along know that there is a lot going on under the hood. In one shape or form, they are engineering marvels making our daily commute more comfortable or shaving seconds off the lap time on a track.
Telemetry data is how cars talk. It is collected by racing teams, enthusiasts, and research and development teams alike. Pi-Por-Tel (https://github.com/vibhubithar/pi-por-tel) or RapberryPi-portable-Telemetry device is a very basic way in which you can start collecting telemetry data and store it appropriately in a time-series database.
Yes, the Time series database is an important aspect of this logger as every data point generated while the car is in motion is with respect to a point in time and GPS coordinates. Once collected and stored you can then visualize it using grafana.
For me, I started this project because whenever we go on long trips especially to hilly regions my 4-year-old sometimes throws up. We have tried a lot of things including getting a car that has air suspension to firm up the ride on twisty sections, which improved the situation a little but not completely.
So I looked for IMU-GPS loggers online but found them limiting or expensive, hence pi-por-tel is an inexpensive way to collect IMU-GPS data from any vehicle.
If you fancy making one for yourself head over to my GitHub for full instructions https://github.com/vibhubithar/pi-por-tel So let's talk about the hardware setup then the software setup.
