The on-board controller monitors and controls the energy system of a yacht
Development goals
- Increase in operational safety
- Increase in the battery life
- Fast charging of the batteries
Increase in operational safety
By displaying the accumulator states, the operator is informed at all times about the availability of the accumulator system. An age-related defect in the accumulator can be diagnosed by a constant decrease in capacity, so replacing the accumulator should be planned in good time.… Continue reading

- Project started in 06/2019
- Project start as an ultrasonic distance sensor with two front sensors
- ESP8266 as an evaluation unit with WLAN
- 12V / 80mA
After some discussions in the forum, the idea came up to use a camera that is installed at spreader height and looks at the foredeck. There are already commercial products such as the CAM100 from Raymarine, but it costs around EUR 700 and can only be integrated into their plotter.… Continue reading

First of all, a few important notes that you should definitely pay attention to.
NMEA2000 is increasingly replacing NMEA0183 as the standard. Unfortunately, NMEA2000 is a very complex protocol and for a long time it was hardly possible to realize your own projects. That has changed with the NMEA2000 library by Timo Lappalainen (https://github.com/ttlappalainen/NMEA2000).
The library supports different microcontrollers, including the ESP32. The ESP32 from Espressiv is very powerful and, thanks to the WLAN and CAN bus interface, is ideal for your own projects.… Continue reading
