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

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
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

The wind sensor Yachta is used to measure wind speed and wind direction on boats. It is installed on the mast and supplied with 12V. The data transmission of the NMEA0183 telegrams takes place wirelessly via WiFi. The wind sensor contains an access point and a small web server. A mobile phone with a web browser is used to display the measured values.… Continue reading

Philippe from France presented us with an interesting project on how, as a blue-water sailor, you can use a cheap satellite communication device to access weather data at any point on earth via SMS. We want to introduce it here. Anyone traveling far from the mainland with their boat needs reliable weather data every day for route planning. The weather data can be obtained in different ways:
In the age of universally available Internet, however, there is a high cost for a satellite system with the corresponding data throughput.… Continue reading

The Yachta wind sensor is a further development of a wind sensor from the Yachta user at bei Thingiverse was presented. The technical principle of operation is based on one Hall sensor for measuring wind speed and on one magnetic rotation sensor for measuring the wind direction. Udo from the german sailing forum took up the idea and made some improvements to the wind sensor.… Continue reading

The universal wind sensor firmware supports various wind sensors. It is based on the firmware for DIY wind sensor WiFi 1000 and has been expanded to include further wind sensor types. Different types of sensors, such as analogue, magnetic and digital, can be connected. The corresponding wind sensor is selected in the firmware. No other settings need to be made.… Continue reading

It is often the case that the anchor winch can only be operated via permanently installed switches and the switches are mounted in such a way that the anchor halyard or the hauling up cannot be properly seen. The use of an additional remote control is much more practical. This allows you to operate the anchor winch from any location and is no longer subject to restrictions.… Continue reading
