Standard built-in instruments with a diameter of 52mm are often used to display various measured values on boats. These can often only be used for very special tasks with very special sensors. Unfortunately, the display layout differs depending on the task and there is no consistent appearance. In the search for a modifiable display, I came across a built-in instrument for an oil pressure gauge of 0...150 psi.... Continue reading
Stefan Kaufmann has on his website https://obenschlaefer.com/ presented an inexpensive energy monitor that is also interesting for boat enthusiasts. He originally built the energy monitor for his camper in order to be able to monitor the energy supply. The system is based on components from Victron on. The centerpiece is a Raspi with the free Venus OS firmware from Victron, which is also included in commercial hardware runs, but in this case on an inexpensive Raspi3B.… Continue reading

The Ruuvi sensor day is a small, smart sensor device. This allows the following data to be recorded:
- temperature
- Humidity
- Air pressure
- 3-axis acceleration sensor
- waterproof case
- Data storage in mobile phone app
- Android and iPhone app available
The data is sent to a data terminal at defined intervals using Bluetooth Low Energy to save energy. This can be a cell phone, for example, where you can look at the data.… Continue reading
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:
- Wall housing 120mm x 80mm x 35mm (W x H x D)
- Resistive touchscreen 2.4 inch (6.14 cm) color TFT with 320 x 240 pixels (ILI9341)
- For D1mini or ESP32 Dev-Kit C V2 / 4
- built-in piezo buzzer
- Integrated 5V voltage regulator (input voltage 9 - 35V DC)
- power consumption approx.

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

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
