    What is better than sharing knowledge? There is a forum, a group or a blog for every taste:



    What do we use donations for?

    Donations are mainly used to finance a booth at Boot in Düsseldorf. We need the money to finance the stand space and the technical equipment of the exhibition stand with electricity and internet. We also finance the exhibitor passes and take out insurance for the exhibition stand. We also create flyers, business cards and posters. The stand itself will be set up and made available free of charge by Dirk, our stand builder.

    Due to Corona, we could not operate a booth at Boot in 2021. As a substitute, we offered online workshops on the Internet. To a small extent, we also use the donations to procure suitable microphones and cameras.

    The paid automatic translation service from Google Translate generates our English websites, which we also finance with donations.

    We are currently not registered as a non-profit organization and can therefore not issue any donation receipts. We park the collected unused funds and use them for the next trade fair appearance. Donations can only be made via PayPal.

    But we are also interested in donations in kind for the construction of the trade fair and our projects. For example, we can use old disused or defective marine instruments for our DIY projects, with which we test the reliability of our self-built devices. Just contact us via  contact form and we mediate the donations in kind to the respective maker.

    Who is behind the project?

    We are a group of makers from the and exchange our ideas there. With our presence at the fair, we also want to introduce the faces behind the projects and get in direct contact with people. The maker team is not limited to just 6 people and is supported by a large number of other makers.

    Norbert Walter is active in the sailing forum and has built one there himself Wind sensor and some other projects presented. He likes the exchange with creative people and is enthusiastic about the variety of ideas in the sailing forum. Professionally, he works in the development of industrial measurement systems.

    Christian Hartz is an enthusiastic sailor on the Chiemsee and a gifted hardware developer with lots of creative ideas. He creates one in his spare time Open hardware for OpenPlotter, which is based on a Raspi Compute module. Professionally, he works as a freelancer in the electronics sector.

    Andreas Vogel is active in the sailing forum and has its navigation software there AVnav presented on the basis of the Raspberry Pi and Android. Professionally, he works as a freelance software developer and architect.

    Andreas Koritnik is active in the sailing forum and deals intensively with maritime communication protocols such as NMEA0183, Seatalk, NMEA2000. Its aim is to give the maker community better access to manufacturer-independent use and expansion of functions with examples of electronics (Arduino and ESP32) and the necessary programs. To this end, he has various projects GitHub provided, including a remote control for a Seatalk autopilot and a NMEA2000 WiFi gateway.

    Michael Maass is active in the sailing forum and enthusiastic about the OpenPlotter idea. In his free time he experimented a lot with NodeRed and also Introductory videos created for this. He especially likes exchanges and collaborations in non-commercial projects. He is a teacher of German and geography, but no longer works in school, but as a media consultant for the state of Schleswig-Holstein.

    Dirk Eversmann is active in the sailing forum and is committed to open source and open hardware. He is the founder of one Maker Shops and has organized and implemented two trade fair appearances at Boot for OpenSeaMap in the past. Professionally, he works in the event sector and is very familiar with trade fair appearances.

    about us

    Open Boat Projects is a platform on which water sports enthusiasts present their self-constructed DIY projects around boating. The idea for this platform was born in the german sailing forum . It started with a trade fair appearance at Boot 2020, where a large number of DIY projects were presented live. The aim of the whole is to show which tools and technical possibilities can be used to implement your own projects. The projects presented are intended to encourage interested parties to implement their own projects and contribute their own ideas that can be used by others. The focus is on open-source and open-hardware as well as sharing ideas. In the meantime a lot of interesting projects have been realized. Further projects will be added in the future. The main exchange takes place in german sailing forum under the heading instead of. We invite everyone interested to take part in the exchange of ideas. You don't have to be an expert to do this. Anyone who has great ideas is welcome to contribute.

    Anyone who always wants to be up to date can do ours Facebook site subscribe to. Current articles and other interesting projects are briefly presented there.
