Important instructions

The articles published on this website are hobby projects of varying quality in terms of functionality, security and documentation. In the case of open source projects, the necessary minimum requirements for security and functionality may not be met, as some of the projects were created by laypeople with limited technical and legal knowledge. The open source projects are to be understood as feasibility studies that show the limited possibilities with which private projects can be implemented. The quality of the resulting solutions are not comparable to commercial solutions. It should be clear to anyone who is interested that the projects presented here are used at your own risk and that errors and disruptions that can have serious consequences are to be expected. Before using your own projects, carry out a risk analysis and take suitable measures to avoid damage and danger to other people.

Handling voltages greater than 50V can be life-threatening. Working with higher voltages should be left to professionals. Batteries of all shapes and sizes store large amounts of energy, which can suddenly discharge in the event of a fault and cause fires. In any case, use suitable protective devices on batteries to reduce the risk.

It is best to acquire the necessary knowledge before you start implementing the project and get help with topics that are unclear to you. Use information sources such as forums or the Internet to gain knowledge. This increases the chances that you can successfully implement your project. Do not operate open source and open hardware projects in safety-critical environments. The use of the projects is at your own risk with the exclusion of liability claims.

NMEA2000TM, NMEA0183TM, SeaTalkTM, SeaSmartTM are registered trademarks of the respective trademark owners. The names are used as synonyms for these protocol types on this page. When reference is made to it in the descriptions, this means open source implementations that do not meet the quality requirements and specifications of the respective brand owners in all respects. The software and hardware are experimental for knowledge acquisition and should not be connected and operated with safety-critical systems. No guarantee can be given for the correct implementation of the protocols and their functional reliability. The integration of open source implementations in certified bus systems can lead to errors, malfunctions and total failures. The use of the open source software and hardware is at your own risk, with the exclusion of liability claims.
