Inspiration
Alpine ski racing athletes with a need of data to track and improve our performance.
What it does
We have created a system with multiple units of a ultrasonic sensor attached to an Arduino to be installed on each gate to not only validate that the racer passed it through the right side, but also to provide a enhanced live time experience for the audience and what's most important, an accurate telemetry for the racer team to allow them to improve the trace on each gate and obtain better results on further races.
How we built it
Each unit consists on an Arduino nano RP2040 and an ultrasonic sensor. On the backend/frontend , we have used nodejs with a Firestore Database.
Challenges we ran into
Log timestamp with milliseconds accuracy with arduinos with no GPS/RTC modules.
Accomplishments that we're proud of
Log results with accuracy. Units connected to a central system with OTA updates capabilities.
What we learned
A LOT
What's next for SK1 Telemetry
Improve code performance on the arduino side. Implement RTC Clock modules for a better timing accuracy. Switch connectivity to LoRa. Make it more scalable. Redesign webapp to implement authentication, better UI and report creations.
