Car power supply for notebooks
Cupák, Pavel ; Šotner, Roman (referee) ; Kubíček, Michal (advisor)
In these days, almost everybody has a laptop. It allows a simple moving of a work space and with a battery capacity of several hours the owner can work almost everywhere. However, the battery has to be recharged from time to time and a socket is not available everywhere. Often you need to recharge when travelling by car and it comes to mind to use the car socket. The bachelor thesis deals with design and implementation of switching power supply for recharging laptops from car socket. The power supply has an easily adjustable output voltage for a simple choice of the right power voltage of a laptop, which is visualized on the display. The power supply is driven by microcontroler ATmega8.

Industrial state indicator
Růžička, Zdenek ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
Diploma work deals with industrial display systems, indicators and their proposal. These systems are used everywhere that is necessary to mediate transmission of information. Own proposal of indicator is very specific and depends on given application and used display. In practice there is possible to use a few types of displays but in this diploma work there are used only sedmisegmental and matrix. Common component of proposal is microcontroller. No less significat and important part of the proposal is a choice of interface and communication protocol. The correct choice of hardware that is completed with software we will obtain complete status indicator.

Multimedia player of non-compressed audio data and images
Sekanina, Viktor ; Šebesta, Jiří (referee) ; Frýza, Tomáš (advisor)
The work deals with hardware and software design of standalone audio player for uncompressed format. Designing device will ensure the connection and operation of the hard drive, browse the directory and files, display bitmap images and play audio records. Next parts of player are also a graphic equalizer and audio power amplifiers for speakers or headphones. A certain complexity of the system is given a relatively high bitrate of uncompressed audio and the need to continuously control of the periphery.

Car4 vehicle remote control enhancement
Nejedlík, Tomáš ; Lamberský, Vojtěch (referee) ; Vejlupek, Josef (advisor)
This work deals with adding the LCD display to the remote control and its programming. At the introduction, we describe available data that we could get from the on-board sensors. Then we describe in detail how are the data transmitted between vehicle and its remote control, how the data are processed and then displayed. Also the modifications performed on the on-board electronic wiring and battery charging are discussed and described.

Modulr RGB LED display
Coufal, Miroslav ; Šťastný, Ladislav (referee) ; Bradáč, Zdeněk (advisor)
The aim of this master’s thesis was the design RGB LED display with Ethernet interface. I created a display module, controlled by a microcontroller ATmega 2560-16AU. These modules can be connected via a serial RS485 standard. Ethernet connection is made via plug-in interface that uses the programmable module Rabbit RCM 3200. I documented a proposal. I tested designed device.

Design of Pump-Inverter
Ferda, Tomáš ; Sládek, Josef (referee) ; Sovják, Richard (advisor)
Subject of this Bachelor’s Thesis is futuristic wall variable-frequency drive design, intended for pumps of up to 3kW power. The thesis deals with current products’ imperfections like plain shapes and/or insufficient display and controls ergonomy. Furthermore, the resulting design is enhanced with SD card data recording functionality and fulfils functional and engineering requirements, as well.
