Hi,
I am in the process of planning for the build of a F104G cockpit.
For some of the gauges we will use an LCD at the back, but for others have to create the gauges.
This means stepper motor or servo motors. An example gauge is Oil Pressure. It starts from 0 at 6 o'clock and ends with 100 at 5 o'clock, which is around a 340 degree travel.
Alternatives found are:
Servo motors
I already bought some sg90 servo motors, and I found out (after they were received) that they can travel only 0 - 180 degrees.
There are a lot of instructables for modifying a servo motor for continuous rotation, but not that much information for fixed controllable 360 degree rotation (or less).
Of course I saw some stepper motors eg. here: http://www.hobbyking.co.uk/hobbyking/store/__86553__Towerpro_MG90D_360_Degree_Mini_Digital_Robotic_Servo_2_4kg_0_048sec_13g.html
Would the MG90D be a good candidate ?
Stepper motors
With the stepper motors, there is a problem with the home zero (0) recognition.
Questions:
Do you know any cheap servo motors with a 360 degree or similar travel?
What is your suggestion, based eventually on your experience?
What will there be the need for a Stepper motor based gauge ?
I am planning to use the gauge through either Link2FS or Mobiflight. Not sure which for now, I am inclined towards mobiflight as I already have the FSUIPC addon.
