@ -2,8 +2,8 @@ Having in mind the O-ESD project aims the following design decisions are made.
(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.
