Stroboscope tachometers
Hortai, František ; Vágner, Martin (referee) ; Beneš, Petr (advisor)
This bachelor’s thesis describes the design of a rotation measuring device using stroboscopic effect. In the first part of my work I have studied the solutions to the problems of rotation measuring, followed by description of the stroboscopic effect. Individual chapter presents a market research of the commercial strobe tachometers. The practical part proposes and designs an own stroboscope. The stroboscope allows manual adjustment, external synchronization, phase shifting. Electronics is controlled by a microcontroller from Atmel, the light source are power LEDs. It was designed a two-sided circuit board by using Eagle Professional 6.1.0. The circuit board was brought to function by planting the components on it. Development continued by creating the driving program for the microcontroller. The end result of my work is functional stroboscopic tachometer in a box together with the necessary electronic components serving for its proper functioning.

Revolution counter of high-speed motors
Biječek, Vilém ; Tomíček, Pavel (referee) ; Skácel, Josef (advisor)
This bachelor thesis deals with two issues. Several methods have been explored to measure rotational speed. Primarily the speed of the high-speed shafts. Based on this, it was found that the most suitable method for this experiment is the optical method. The second focus of this work was design and development of the device. A large part is devoted to the selection and application of components, and simulations of circuit connections, which have been successfully tested and implemented. The output is an accurately measured value shown on the display. It also included the design of printed circuit boards, one for analogue information processing and the other for placing the microcontroller with the display.
