(1) Two rechargeable batteries in form factor 18650 will be used, followed by two separate DC/DC converters as the power supply. (2) LCD with 4x20 characters with additional tasters and one rotary encoder will be used as the user interface. -(3) Arduino Nano will be used as microcontroller (it could be replaced with Arduino Every or other microcontrollers with the same board size and number/raster of pins). +(3) Arduino Nano will be used as a microcontroller (it could be replaced with Arduino Every or other microcontrollers with the same board size and number/raster of pins). (4) Flyback topology will be used in high-voltage generator. Trafos that are custom made using ETD29 or ETD49 cores will be used. Trafo secondary will be connected to the input of a single cascade, while the polarity of the output voltage will be controllable. (5) Shaper #1 topology is first in line to be used. -(6) Reed relay with 5 V turn-on voltage will be used as high-voltage switch with additional transistor for providing current for relay control side. -(7) Acrylic plastic will be used as mechanical support, while all PCBs will be made of FR4 with standard thickness of 1.57 mm. +(6) Reed relay with 5 V turn-on voltage will be used as a high-voltage switch with additional transistor for providing current for the relay control side. +(7) Acrylic plastic will be used as mechanical support, while all PCBs will be made of FR4 with a standard thickness of 1.57 mm.
