The task of this thesis is a hollow clock with hands that create the impression of floating in space thanks to the absence of a classic dial. The exact time setting is based on an RTC module, while the possibility of upgrading the system for automatic synchronization via WiFi network and NTP server is envisaged. The movement of the hands is performed using a stepper motor and Hall sensor for the reference position, and the entire system is controlled by a D1 Wemos Mini microcontroller. In addition to electronic control, an appropriate printed circuit board (PCB) was created, as well as 3D models of the clock case that enable a reliable and aesthetically impressive mechanical assembly. The project successfully combines elements of electrical engineering, mechatronics and programming, and results in a functional and stable system that can serve as a basis for further upgrades and application for educational purposes.

U ovom radu izrađena je šuplja ura s kazaljkama koje stvaraju dojam lebdenja u prostoru zahvaljujući izostanku klasičnog brojčanika. Podešavanje točnog vremena temelji se na RTC modulu, dok je predviđena mogućnost nadogradnje sustava za automatsku sinkronizaciju putem WiFi mreže i NTP poslužitelja. Pokretanje kazaljki izvedeno je korištenjem koračnog motora i Hall senzora za referentnu poziciju, a cjelokupni sustav nadzire mikroupravljač D1 Wemos Mini. Uz elektroničko upravljanje, izrađena je i odgovarajuća tiskana pločica (PCB), kao i 3D modeli kućišta sata koji omogućuju pouzdan i estetski dojmljiv mehanički sklop. Projekt uspješno spaja elemente elektrotehnike, mehatronike i programiranja, te rezultira funkcionalnim i stabilnim sustavom koji može služiti kao osnova za daljnje nadogradnje i primjenu u edukacijske svrhe.
