DC/DC step-up converter for notebook
Škunda, Michal ; Klíma, Bohumil (referee) ; Červinka, Dalibor (advisor)
Given bachelor’s thesis devoted to a proposal and implementation of transducer STEP-UP for supplying of notebook in car. Introduction presents dividing of switching power supplies followed by a choice and a proposal of power supply. In this work we can find the specific proposal of inductor, the proposal of electronic connexion and the proposal of PCB layout. There is a software EAGLE used for the design of PCB layout. In the last part of work there are particular courses of current and voltage that characterize power supply pictured. The work contains measured load characteristic of switching power supply loaded by notebook as well. Notebooks need to have quality power supplies that is why there was a special attention paid to the quality of supply and its electric parameters.

Wireless accelerometer modul
Lysoň, Jakub ; Odstrčilík, Jan (referee) ; Bubník, Karel (advisor)
This master’s thesis describes a wireless accelerometer module. The aim of this work was to study the properties and involvement of the accelerometer, wireless module design for data transfering from the accelerometer to the PC and the module implementation. As a wireless device is used bluetooth module that enables communication between the product and the computer. The wireless module used rechargable lithium ion battery that helps keep module alive without adapter or net cable.

Subharmonic Mixers for Microwave Bands
Kintr, Jindřich ; Frydrych, Jiří (referee) ; Urbanec, Tomáš (advisor)
The task of this master’s thesis is design and implementation subharmonic mixer for the microwave band. Subharmonic mixer is based on the principle of antiparallel diode. In the first two parts are theoretically described mixers (subharmonic mixer) and topology suitable for implementation. Another work describes the design subharmonic mixer. The proposal is implemented in the program Ansoft designer. DPS is created in Eagle or in Ansoft Designer. The mixers are designed and implemented first on the lower frequency and consequently at higher frequencies (24,048 GHz and 47,088 GHz). Work also includes the measurement results of the mixers.

Industrial programmer Atmel AVR microcontrollers
Gryžboň, Jan ; Hanák, Pavel (referee) ; Pavelka, Ondřej (advisor)
The aim of this thesis is to design and implement an industrial programmer AVR microcontrollers from Atmel. The first section provides the theoretical knowledge of the AVR microcontroller. Furthermore, comparison of methods for programming the microcontroller and the selected method is an analysis of the speed of programming. The following is the entire design of industrial programmer which is implemented in the programming environment Eagle. In the penultimate part of the proposal is designed PCB. The final section is devoted to the revival of the programmer and programming.

Remote controled robot unit
Kratochvíl, Robert ; Kosina, Petr (referee) ; Pavlík, Michal (advisor)
Labor is handling of the programming movement functions and construction of the simple robot, a design of double-layer printed circuit boards for its implementation and realizes remote control. Motional functions were tested using the test, hand-soldered, double-layer board implemented on soldery bay of joints and demonstrated on prototype. The movements themselves have been simulated using LEDs, the remaining parts were up to the type of casing the same with a planned final design of the board. Using the prototype we demonstrated complete exact movements. For the control microcontroller was chosen for the board of the robot and controller ATMEGA16, communication takes place through USART bus of this microcontrollers. Programming was carried out in CodeVision and AVR Studio, design of printed circuit boards in the EAGLE.

A Laboratory Task: Oscilloscope Measurement
Malý, Ondřej ; Steinbauer, Miloslav (referee) ; Marcoň, Petr (advisor)
Bachelor thesis deals with the design of a signal generator for a laboratory task of the subject HELE. As a generating chip is used ICL 8038 that can generate three types of waveform – sinus, square wave and triangle. The frequency range is from 20 Hz to 20 kHz in selected circuit. Output is connected to oscilloscope probe, but also to 3.5mm headphone jack through which can be the selected waveform listened to on the connected headphones or speakers and measure the audible threshold.

Design of control board for autonomous mobile robot.
Mašek, Petr ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
This bachelor's thesis deals with design and realization of the control board, that enables the control of an autonomous mobile robot. Simultaneously it deals with possible control alternatives of the similar robots concerning the construction. The outcome of this thesis is the control board, that communicates with the computer via the Bluetooth technology. The position of the robot is controlled via two differential drives and few infrared sensors are used to collision avoidance. The board is composed of standard parts available.
