Design of dual regulated power supply
Moštěk, Jiří ; Kubíček, Michal (referee) ; Brančík, Lubomír (advisor)
This bachelor thesis deals with design and construction of a symmetric stabilized power supply provided with an adjustable electronic current fuse. The concept of source is chosen as a linear with two-output voltage ranges. The first range is possible to regulate the voltage from 0V to 20V with current limit 2mA – 4A or 2mA – 8A. The second voltage range allows you to adjust the output voltage from 0V to 40V with current limit 2mA – 4A. Included in this bachelor thesis is the simulation source, testing in non-soldering field, PCB design, commissioning, draft cooling and design of structural solutions. At the end of bachelor thesis are given the results of measurements laboratory resources and photos.

Small CNC machine
Moštěk, Jiří ; Matěj, Zdeněk (referee) ; Záplata, Filip (advisor)
This diploma thesis deals with the design and construction of a three-axis CNC machine primarily designed for PCB drilling and production of front panels for various electronic devices. All three axes are driven by stepper motors NEMA 23 which are connected to stepper motor drivers L6470. Processor STM32F407 is used to control the whole machine. The wiring is completed by a LCD display with touchscreen which is used to communicate with user. Data for drilling can be entering manually or via USB inerface. Part of this thesis is the selection of a suitable construction and components, assembling equipment, wiring design of electronic circuits and writing the code to control the machine. Finally, the parameters of the designed device have been measured.
