First of all, a few important notes that you should definitely pay attention to.
GaladrielMap is a web-based navigation software by Vladimir Kalachikhin. The name of the software is named after its boot. The software is based on a large number of PHP scripts that generate websites and are published via a web server. The websites can be viewed on any device such as mobile phones, tablets and laptops.

The AZ touch Mod is a small 2.4 ″ touch color display with 320 x 240 pixels. On the base board can be used as a control unit ESP32C or a Wemos D1 mini be attached. A small breadboard allows you to set up your own circuits to expand the display.
The AZ-Touch has the following features:
First of all, a few important notes that you should definitely pay attention to.
SensESP is a library that facilitates the integration of ESP8266 and ESP32 based sensors and actuators in a signaK network. The framework is based on PlatformIO and is mostly written in C++. Basically, recurring and important functions are mapped by the framework, so that programming and connecting your own sensors to SignalK is quite easy.… Continue reading

Video presentation in German on the OBP 60 multifunctional display (45min presentation, 30min discussion)
After we have dealt with the M5Stack as a multifunction display have been busy and were able to show some applications at Boot 2020, we are taking a new approach for a new multifunction display.… Continue reading
After Christian at Boot 2020 in connection with his plotter had introduced a Bluetooth remote control there is now a new IR remote control. It turned out that Bluetooth is not really suitable for a remote control, as there were significant problems with Linux when creating the connection and the remote control did not work as expected.… Continue reading
The I2CModules of the Horter company (LxW 65x45mm) can be used for boat automation because they can be connected to any microcontroller and the Rasperry Pi. The I2C bus is actually intended for communication between ICs on a circuit board. But there are also numerous Extensions with which the bus signals can be amplified and electrically isolated so that longer distances of up to 50m can be bridged with shielded cables.… Continue reading

Gerry from the Sailing Forums built a keel sensor to show the extended depth of a liftable keel. In addition to the keel depth, the heel is also displayed. The keel depth is measured using an ultrasonic sensor. For this purpose, the sensor is mounted inside the keel box and looks down on the lowered keel. The measurement data can be transmitted via WLAN, for example… Continue reading
Fig.MAIANA AIS transponder transmitting and receiving part with fixed antenna (Open Marine)
Peter Antypas self-built an AIS class B receiver / transmitter and presented it on Github:

The device combines the following functions:
The AIS transponder consists of a transmitting and receiving part with a permanently attached antenna, which is connected to an adapter box via a shielded cable.… Continue reading
AIS Radar Pro receives the AIS messages from the connected AIS receiver (receiver), decodes the information contained and displays them graphically and in text form. From the position and speed data received, AIS Radar determines possible collision opponents, the distance in nautical miles and minutes to the closest approach to the collision opponent, as well as the location and time of a possible collision. AIS Radar Pro follows the simple RG Marine principle: Anything RED is dangerous.… Continue reading
Fig.: Ultrasonic level measurement
The idea of the level sensor arose from several sailors in the sailing forum. Andreas built a prototype and tested it on various objects. A simple replica is possible by using ready-to-buy modules. The ultrasonic sensor records liquid levels in a tank and sends NMEA0183 telegrams to the on-board network via WLAN. These can then be visualized in AVnav or OpenCPN, for example.… Continue reading
