Aquaristics is one of the most widespread domestic hobbies. Various specialized devices such as a filter, a water heater and lights are used to keep the stocking of the aquarium alive and well. All of the products available on the market today are not connected to any communal system. Instead, they all work independently. The aim of the thesis was to innovate, develop, manufacture and use a new product used to help aquarists. System of a low-profile system integrated fish feeder is built in two main parts. The fish feeder itself and a main system computer. We developed software which controls the whole aquarium. The fish feeder was designed using the latest in 3D modelling technology. For the manufacturing we used two unconventional manufacturing methods. 3D Printing and abrasive water jet cutting. For the system computer we used an Arduino microcontroller, which was programmed in C++ programing language. The product was tested and it achieved all of our initial goals. It successfully repels moisture and allows for the end user to be absent for multiple days. The system controls the filter, LED lights and the fish feeder itself. Users have now less work to do and the esthetic purpose of an aquarium was not compromised. The operating conditions were measured and improvements, based on the findings were proposed.
