19 November 2004

This project’s objective is to describe and control a DC stepping motor. Qualitative stepper motor theory is presented. An example driver with schematic using the PIC16F876 programmed in C is included.

The mini-project is available here.

Project: Electronic Directional Gyro

Electronic Directional Gyro

Charles O'Neill

2004

This project developed an one degree-of-freedom electronic aircraft directional
gyro (DG). The mechanical inertial gyro in a 1960’s vintage DG was removed
and replaced with an stepping motor driven by a micro controller connected to
an electronic rate gyro.
