Controlling LEGO Powered-up Hub from EV3
Potoček, Jakub ; Polčák, Libor (referee) ; Hranický, Radek (advisor)
This work deals with the communication between two incompatible programmable LEGO bricks, the LEGO Mindstorms EV3 and the LEGO Control+ Technic Hub. The task of this work was to create a communication interface enabling the transfer of data between these two bricks and thus enable the EV3 brick to send and possibly also receive data from the Technic hub brick. During the creation of this work, I designed and constructed two prototypes using an optical interface for data transmission. The second prototype enables two-way communication. This enables data from sensors and function return values to be transferred to EV3. Despite the fact that the resulting solution does not allow fast enough data transfer due to the technical limitations of the Technic hub brick, this solution is suitable for use by owners of these LEGO building blocks looking for ways to use both bricks when creating models.

Electronic Drum Control Module
Doležal, Karel ; Růžička, Richard (referee) ; Šimek, Václav (advisor)
This paper deals with development and construction of an electronic drum module. The purpose of the device is to capture signals from an electronic drumkit and to produce sound accordingly. Firstly, a protoype with no sound output is constructed to demonstrate an ability to capture input signals. Based on its function, parameters for a final device are determined. Then, electronic component selection and design of printed circuit boards is described with an aim to maximalize polyphony and minimize latency of the sound generator. After that, firmware with software mixing algorithm is designed. Lastly, testing and measurement of real device parameters is performed.
