Construction
Production of the PCB is a greater challenge. The drawing of the panel is much more complex and denser than
the previous ones. It was successful to produce this PCB using the so called “blue-foil” technology. Other
photo-resistive sprays like Positiv-20 can also be used. Check the PCB thoroughly before placing components
because it would not be possible to repair foil under integrated circuits. Shift registers are placed onto the foil
side while LED displays are to be inserted onto the component side.
Final adjustments
Final adjustments are similar in case of both versions. First step is to adjust the two variable resistors named
„OUT VOLTAGE ADJUST” on the back side of the rotator to produce maximum voltage on the connector.
Start with the adjustment of the shift. Connect the interface to the original controller of the rotator. The drawing
