ESP32 + SignalK: Bringing Old Analogue Gauges Back to Life

In this video, I show how to drive older analogue marine gauges using an ESP32, pulling live data from a SignalK server using the SignalK Listener. This is a great way to reuse classic or legacy gauges while upgrading your boat’s electronics to a modern, open-source system. #SignalK #ESP32 #MarineElectronics We cover: ✅ Why an ESP32 is ideal for marine electronics projects ✅ How to use SignalK Listener to read live data ✅ Mapping SignalK data to analogue gauge outputs ✅ Driving older gauges with modern digital inputs ✅ Practical tips for reliability on a sailboat ✅ Trigger outputs from your SignalK Data If you’re upgrading your boat electronics, experimenting with SignalK, or looking for DIY ways to integrate old instruments with new systems, this project is a powerful and affordable solution. This setup is perfect for sailors who want modern data with classic displays, without replacing everything with expensive proprietary instruments. ⚓ Ideal for: • SignalK users • ESP32 & Arduino-style developers • DIY marine electronics projects • Sailboat refits and upgrades Timestamp 00:00 Intro #SailboatElectronics #BoatTech #DIYElectronics #AnalogGauges #MarineInstruments #OpenSourceMarine #SailboatDIY #BoatLife #EmbeddedSystems #ESP32Project Our Website: https://boatingwiththebaileys.com Social Media & Links: Facebook: https://facebook.com/BoatingBaileys Instagram: https://instagram.com/boatingwiththebaileys/ Youtube: https://www.youtube.com/c/BoatingwiththeBaileys GitHub: https://github.com/Boatingwiththebaileys If you wish to support us: https://ko-fi.com/boatingwiththebaileys
