The Compustar schematics. Part 2: the display board

This is the second part of the Celestron Compustar schematics. You can find Part 1 here: https://www.aemfoto.it/wp/2017/05/31/the-compustar-schematics-part-1-the-microprocessor-board/. As I did in part 1, since there is no silk screen on the board, the designators (IC1, R1, and so on…) are just made up, and may also be quite randomly assigned. Moreover, I’ve not put in the …

Already …

EqPad: an Arduino joystick for Eqmod

Using regularly EqAscom to drive our EQ6 mount, we found the necessity to move the telescope in an easy way without having to use the PC keyboard or mouse. Since EqAscom can use a joystick to do this, we realized a dedicated joystick.   Mode of operation In addition to the standard four movement keys …
