Light decoration with LEDs
Paus, Anton ; Fedra, Zbyněk (referee) ; Zelinka, Petr (advisor)
The aim of this bachelor´s project was to explore the possibilities of the design and subsequent realisation of a light decoration with LEDs. In the theoretical part of the project the control options of a microcontroller and various LED driving circuits were discussed according to available sources. As the decoration should be sensitive to changes of ambient light conditions, attention was given to photosensitive parts such as phototransistor and photoresistor. According to this information the most suitable circuits were chosen for the final design (microcontroller ATmega16 and LED driver SCT 2024C). Thereafter the printed circuit board was designed and consequently realized. Software that controls the decoration was developed using the operational device. The outcome of work is a light decoration composed of three boards with possibility to connect another ones.

Microsolder controlled by microprocessor
Stavělík, Jiří ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
This thesis describes circuit design and realization of the power and control system, which can hold constant temperature of solder tip. Control system is based on microcontroller Atmega328 of company Atmel, part of the work is the implementation and debugging control software. This solution allows to enter temperature by rotary encoder and to show the real temperature on LCD displey. This hardware also detects disconnection of solder tip, acoustic signals when the required temperature is reached and it holds last set temperature.

Processing of the RC plane model telemetry
Žák, Tomáš ; Fedra, Zbyněk (referee) ; Prokopec, Jan (advisor)
Bachelor’s project focuses on problematic about scanning state of RC plane model, during the fly. In detail there is described internal and external structure, including communication. Main objective of work is design functional board for scanning state of RC plane model, during the fly. There is used akcelerometer for scanning actual state of plane. Accelerometer sends measured data in digital form to microcontroller for evaluating. List of used components is in the enclosure.

Design and implementation of managed PoE injector
Frkal, Pavel ; Frolka, Jakub (referee) ; Krajsa, Ondřej (advisor)
This study deals with power supply for network devices using existing structured cabling. Various power supplies are analysed including their limitations and also deals with measuring of the consumed energy. The outcome is 24-port passive PoE injector for remote power supply of network equipment. It's suitable namely for remote devices which lacks built-in PoE support as these do not need major modifications (using passive injection). Power options including current measurement may be done via administrative web interface.
