The idea of this AVnav plugin is to display an instrument that contains all the basic information needed for sailing. With the possibility of showing this display directly on the map at the boat position, the sailor has all the information at a glance. The laylines tell you the quickest bearing to a waypoint upwind, and when they are shown on the chart you can follow those lines.… Continue reading

Anchor light automatic with Shelly 1
Fig. Shelly 1
Anyone who anchors is obliged to set an anchor light so that you can be recognized on the open water surface in the dark. Typically, the light is switched on manually at dusk and off again at sunrise. There is no problem switching it on. But often you forget to switch it off and the anchor light is then permanently on and consumes electricity unnecessarily.… Continue reading
Lilygo T-Watch 2020 with connection to SignalK
Fig. Lilygo T-Watch 2020 (Lilygo)
Jan Dytrych has started a software project to be able to display data from SignalK and receive alarms with a smart watch. Not just any common clock under Android is used as a smart watch. He uses the smart watch Liligo T Watch 2020. The special feature of this clock is that it has an ESP32 installed as a processor and can be controlled via the Arduino IDE or… Continue reading
Magnetix - a digital compass with NMEA2000

why
I've always found the idea of not only showing the course on my plotter when the boat is moving, but also when it's bobbing along quietly, I've always found it exciting.
After searching the I-Net for different manufacturers, it quickly became clear that I might not need an e-compass on board at current prices.… Continue reading

Where the name qtVlm for the navigation and weather routing software comes from is not known. In any case, qtVlm is worth a look for those who are looking for a freeware navigation software with basic functions. Depending on further wishes, the software can be expanded with add-ons that are subject to a fee. If you need it, you can also book telephone or email support for a fee.… Continue reading
Air pressure level sensor
Fig. Control box with pump, pressure sensor and valves
In the Facebook group Raspberry Pi for Boats I saw a cool solution for a level measurement. Erik from Finland constructed a monitor for 4 tanks with an air pressure sensor. The functional principle is based on the displacement of liquids in a measuring tube. A corresponding air pressure then builds up in the measuring tube, which is proportional to the filling level.… Continue reading
Volvo Penta NMEA2000 interface
First of all, a few important notes that you should definitely pay attention to.
Disclaimer: The descriptions of the wiring and the pin assignments correspond to what I found in my boat. Therefore, if you want to rebuild the interface, you have to make sure that the wiring and pin assignments are identical on your own boat or adapt the interface accordingly. The entire description of this solution is in an experimental state and comes without any warranty.... Continue reading
