Building Custom Marine Displays with ESP32 & SignalK (Gauges, Dynamic Icons & Alerts)

In this video, I showcase custom marine displays built using an ESP32, powered by SignalK data and designed specifically for flexible, modern boat instrumentation. These displays feature custom gauge designs, dynamic icons, alerting, and web-based configuration, making them ideal for upgrading older boats or building fully bespoke marine dashboards. What’s covered in this project: ✅ Using an ESP32 to drive marine displays ✅ Pulling live data from a SignalK server ✅ Designing custom digital gauges ✅ Dynamic icons that change based on conditions ✅ Alerting and warnings for critical data ✅ Web-based configuration (no reflashing required) This approach allows you to build modern, responsive marine displays using low-cost hardware and open standards — perfect for sailors who want full control over their boat electronics without proprietary systems. ⚓ Ideal for: • DIY marine electronics projects • SignalK users • ESP32 & embedded developers • Sailboat refits and custom dashboards • Open-source boat tech enthusiasts If you enjoy DIY boat tech, ESP32 projects, and open marine systems, consider subscribing — more builds and walkthroughs coming.
