🚗 Hackathon: MJV Internet of Things Hackathon
In May 2015, I participated in the MJV Internet of Things Hackathon – Capítulo 2: Relação entre o carro e o motorista, held at MJV’s office in Vila Olímpia, São Paulo. The event brought together developers, designers, and engineers for a weekend of prototyping and idea sharing.
Our team worked on a solution for monitoring tire pressure using Arduino sensors, sending real-time data over Bluetooth to a custom iOS app. The goal was to improve vehicle safety and efficiency through simple telemetry and user feedback.
What we built:
- Pressure sensors interfaced with an Arduino-compatible board
- Bluetooth communication with an iPhone app
- Live feedback showing tire status to the driver
The hackathon was intense, hands-on, and filled with problem solving. One of the best moments was meeting Ivan Seidel (@ivanseidel) — at one point, we were debugging a concurrency issue with the Arduino logic, and I mentioned using a Threads library. Ivan was nearby and casually said, “I built that library.” Classic hackathon moment.
