Attitude Indicator


attitude indicator
Pitch and Bank to do two moves. I used two stepper motors.
The Pitch shaft penetrates, so I connected it with her gear to shift the motor shaft from the center of the Pitch rotation.
The display part of the hemisphere was make by embossing work from 2mm aluminum plate. I tried to see if I could make such a small curved surface by embossing it out.
Rather than searching around for spherical plastic materials, you can make the one you need. This is a good opportunity to improve my skills.
Unlike other meters, the scale cannot be printed with a printer, but a small sticker is attached to the spherical surface.
Since the entire Pitch part on which the motor is mounted is rotated by Bank, we planned to bring the center of gravity as close to the central axis as possible.

The pointer bends the brass wire 0.5 mm. He cut a 3mm rod short and made a notch on the back to pinch the brass wire in order to make the central round part a nice circle. Assembling only by soldering is difficult due to heat transfer.
Since it moves three-dimensionally, it is difficult to adjust it in some places.

Config Setting

I've been experimenting with config settings, but it looks good at last.
Transform data from FSUIPC to angle value (in 1° increments)
Pitch --- Round (-($ * (360/65536) / 65536), 0)
Bank --- $ * (360/65536) / 65536
By using a gear, the reversed rotation direction is returned by Compare.
In addition, I try not to output values that exceed the movable range of -40° to + 40°.
