Control unit for positioning control of the experimental positional table
Fries, Lukáš ; Řezníček, Michal (referee) ; Adámek, Martin (advisor)
The work is devoted to the theoretical characteristics of the used components and its functioning. The main part is focused on practical design and build a functional device for control the position of the table, which is part of some unspecified workplace. Attention is mainly concentrated on the ATmega328, which is part of the module Arduino for control sub systems. The document describes a closer communication with the computer, which can be selected as a control element positioning apparatus. Change of position is provided by two stepper motors. The primary control was designed using buttons and the position information is the operator transmitted to the display. The whole concept is subject to the requirements on the reliability and accuracy with an emphasis on simple operation.
Research of lead-free solder alloys from the viewpoint of thermoelectric voltages
Fries, Lukáš ; Jankovský, Jaroslav (referee) ; Otáhal, Alexandr (advisor)
The thesis deals with the theoretical investigation of the thermoelectric tensions in lead-free solder. The theory introduces the reader to the formation and composition of solder joints, thermoelectric properties and behavior in circuits. Part of the thesis is the design and optimization of the measuring tool for lead-free solder and product samples with measuring.
