MIDI to DMX signal converter for synchronizing stage lighting with live music
Hajdúch, Patrik ; Záviška, Pavel (referee) ; Sikora, Marek (advisor)
This bachelor thesis focuses on designing a device for converting MIDI signals to DMX signals. The converter runs on the ATmega328P microprocessor with the Arduino bootloader and is capable of converting Note On, Note Off, and Control Change messages into changes in the DMX output signal. For the conversion, a map consisting of three profiles is used, which is editable using a desktop app and saved on an external EEPROM. This allows the converter to be used universally with many different DMX systems. The device is housed in an enclosure with dimensions that allow it to be stored within a single rack unit. The converter allows for fully automatic control of stage lighting and other stage equipment in synchronization with music and creating complex scenes using the widely used MIDI protocol.

Wireless data logger for environmental monitoring - server-side
Bártek, Jiří ; Kolářová, Jana (referee) ; Sekora, Jiří (advisor)
This work describes the design and implementation of the server-side component, which is part of a comprehensive task for measuring temperature in medical storage spaces and sending the measured temperature at specified time intervals. The created device will receive the measured data and subsequently send it to an e-mail address. The introductory part deals with the legislation related to the storage of medicines and further provides the reader with theoretical information about the used devices and protocols. The next section of the work introduces the implementation of the device and software solution. The outcome of the work is a device capable of communicating with another microcontroller and sending the received data to a selected e-mail address for subsequent archiving.

Dashboard for Smart Home Status Focused on Low Consumption Installations
Fišer, Tomáš ; Hynek, Jiří (referee) ; John, Petr (advisor)
In the rapidly evolving concept of IoT, or a network consisting of physical devices with electronic and software capabilities to interconnect and collaborate to perform autonomous actions without human intervention, dashboards are an important element for users, providing data visualizations and controls over data. This work deals with the creation of a dashboard that has as main goals low energy consumption compared to traditional solutions, simple control interface and clear data visualization. It tries to meet the parameter of low power consumption by using energy efficient computing hardware, ESP32 microcontroller and by using E-ink display panel which again has low power consumption. The resulting dashboard should be able to run on batteries for long periods of time without the need to replace or recharge the batteries.

Stereo ADC and DAC converter for audio
Koiš, Christopher ; Polák, Ladislav (referee) ; Kratochvíl, Tomáš (advisor)
This bachelor's thesis deals with the problem of designing a programmable digital sound processor with its input connected to a device, such as a personal computer or a mobile phone, and an output intended for headphones. One segment of this thesis handles digital filters, specifically FIR and IIR filters. The MATLAB environment was used to design the filters shown in this thesis. Furthermore, the buses SPI, I2C and I2S that are used on the device are described. The parameters of individual functional blocks are summarized, and the designed circuit schematic are displayed in this thesis. In the practical part of this thesis a prototype printed ciruit board was designed and its' electrical parameters were measured and processed. Finally, the last part of this thesis describes the inner workings of the program that the microcontroller executes.

Optimization of the digitron testing process
Stuchlík, Lukáš ; Valach, Soběslav (referee) ; Honec, Peter (advisor)
This bachelor thesis focuses on the optimization of a nixie aging machine in order to increase its reliability. In the introductory part of the thesis, an analysis of the current state of the machine is made, describing its unreliable operation and related problems in the production process. Based on this analysis, specific modifications in both hardware and software areas have been proposed. The main changes were the change of topology for current control and the addition of necessary components or complete circuits. These modifications were then implemented, which included the fabrication and testing of new printed circuit boards (PCBs) and the implementation of new firmware. In conclusion, it is confirmed that the modified machine exhibits reliable operation for the purposes of actual aging, but further requires minor modifications.

System for Electricity Consumption Registration
Hockicko, Matej ; Zachariášová, Marcela (referee) ; Mrázek, Vojtěch (advisor)
The aim of this work is to design a system to record the consumed electricity. This system will consist of an embedded device that monitors the optical output of the meter and a mobile application, which will be able to download and display the measured data using bluetooth technology. The embedded system will consist of a microcontroller from Nordic Semiconductor. The mobile application will be programmed in the Flutter framework. Historically measured data will be stored on the cloud. The focus of the design will be on the battery life of the embedded device, which will be powered by a CR2032 battery. The main benefit of this work is the ability to monitor electricity consumption using the embedded device and mobile application without the need of owning a smart meter.

Determining Stress Level from Heart Rate Monitoring
Hodulík, Hynek ; Strnadel, Josef (referee) ; Bidlo, Michal (advisor)
This thesis outlines the development of a prototype wearable embedded device intended for stress detection via physiological measurements utilizing an EKG sensor. Communication for the device is facilitated through Bluetooth LE. Accompanying the device is an algorithm designed to estimate stress levels locally based on collected heart rate variability data. Following a comparison of various methods, a multilayer perceptron was selected for stress detection. The proposed solution demonstrates an 85% accuracy rate in stress detection on WESAD dataset.

Controlling LEGO Technic Active Elements from EV3
Blaško, Daniel ; Polčák, Libor (referee) ; Hranický, Radek (advisor)
LEGO Mindstorms je populárna rada programovateľných kociek s rozsiahlou sadou funkcií, ktorá už 25 rokov pomáha učiť deti základy robotiky a počítačových vied, a ktorá sa teší širokej komunitnej podpore. Cieľom tejto bakalárskej práce je vytvoriť hardvérové a softvérové riešenia, ktoré zlepšia kompatibilitu medzi kockou Mindstorms EV3 a ostatnými motorizovanými LEGO súčiastkami, s primárnym zameraním sa na produktovú radu Power Functions. V rámci tejto práce boli v rôznych iteráciách vytvorené radiče, ktoré rozširujú možnosti kocky EV3 ovládať motory, s použitím vlastných návrhov dizajnov plošných spojov a 3D tlačených puzdier. Okrem nich boli vyvinuté softvérové kódovacie bloky, ktoré umožňujú kocke komunikovať s týmito radičmi a ďalšími UART zariadeniami.
