Not much progress in the attitude indicator, because .. It has been snowing heavily … And we had to make some snowmen!

Finally I managed to install all the small wheels on the (almost) right position and now the instrument is working again:


I finished the board to control the attitude indicator by adding PWM sin generator and reading SIN/Cos values from resolver, now I can read the position from the attitude indicator. Now it’s just a matter of coding a PID controller on the microcontroller to position the indicator to the desired position.

This is the prototype board

A video showing how it works:
