Metal detector for industrial use
Stehno, Rostislav ; Friedl, Martin (referee) ; Szabó, Zoltán (advisor)
The goal of this project is explore and study the ways of metal detecting and create a metal detector for industrial use. During a project development, the device size and user easy interface were the basic requirement. As a visual device was chosen LCD touch display, which is very important as a user-friendly interface. For math calculations and right function of device will be implemented microcontroller from Atmel corporation. As a data storage will be used a flash memory with 16MB of size. When the device were inventing, a lot of methods were studied and the impulse detect method were chosen which is the most perspective way of metal detecting. Device will communicate with PC trough a USB port. The device will have a battery which allows device to run for a few hours. The prototype of PCB were developed. Few mistakes has been discovered, while the device were constructed, but they were solved successfully.

Development Board for 32-bit Microcontroller Atmel AT91SAM9261
Demín, Martin ; Slaný, Karel (referee) ; Šimek, Václav (advisor)
Vestavený hardware je velice populární v této době. Proto jsme se rozhodli vytvořit desku s mikrokontrolérem AT91SAM9261 spolu so standartným a nestandartným hardwarem. Standartným, běžným by se dal nazvat port LAN alebo audio vstup-výstup. Nestandartným, špecialním by mohl být obvod FPGA firmy Xilinx o velikosti 200k. Toto dovoluje využít zažízení v oblastech, kde výpočetní síla obyčejnýho CPU již není dostačující.

Altitmeter for RC aircraft models
Švec, Jan ; Frýza, Tomáš (referee) ; Prokopec, Jan (advisor)
The aim of my bachelor thesis is to design an altimeter, who uses to record the attitude of the model "RC plane" evaluation of the current atmospheric pressure. The data are saved during the flight into the memory.The data can be transferred to PC after recording through the USB . The software on PC communicates with the device and ensuring the conversion of recorded pressure to altitude RC model.

Brightness control of light sources
Dostál, Lukáš ; Vorel, Pavel (referee) ; Huták, Petr (advisor)
Thesis is focus on brightness control of lighting sources. The first objective of the thesis is to determine basic concepts and explain interrealationships among particular magnitudes of lifting technology. Further is necessary describe functionality, particular light sources and thein possibility of use in practise. There is also outline issue of darkfall of particular types of sources and their evolution. The other part of thesis compare energy output of lighting sources and describe their possible future development. Further this thesis deals with options of regulating of brightness for LED moduls. There is also proposal of acceptable amperage regulator LED moduls including its software - microcontrol ATMEL AVG. Microcontrol ATMEL AVG Tiny 13 is programme in C language within computer environment AVR Studio 4 and will be record through the use of AVR Dragon.

Automatic control system for a hot water and hot fireplaces inserts
Hofman, Miroslav ; Marcoň, Petr (referee) ; Friedl, Martin (advisor)
The work deals with the design automatic control systems for hot water and hot fireplace inserts. Control panel with LCD display and buttons to adjust the temperature in the room is connected to temperature sensors, pumps and fans. Data are processed by a microprocessor Atmel. Microprocessor program is written in C, in the environment AVR Studio 4. Microprocessor with peripherals defines the room temperature.

DC/DC converter 12 V to 300 V
Buba, Ondřej ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
The thesis deals with design of switching power supply to power the oscilloscope. In this project the topology of the DC-DC converter is chosen, the pulse transformer and the output coil is designed. The control circuit is also choosen a suggested. This circuit will be replaced with microcontroler ATMEL in the second part of this thesis. The microcontroler will be programmed to replace the control circuit.

Temperature and humidity monitoring devices with wirelless communication
Horváth, Michal ; Baštán, Ondřej (referee) ; Bradáč, Zdeněk (advisor)
The diploma thesis is about designing device which monitors temperature and humidity. In the first part of thesis are explained basic terms, importance of key variables and on market offered products are described. After that the thesis describes device concept design with schematic designs. From designed schematics are described printed circuit board designs. Next part is about device commissioning and correction of errors caused by incorrect design. Last part is about program designing and device testing.
