Laser Gimbal - 28BYJ-48 Stepper Motor
Description
# Laser Gimbal This project uses two 28BYJ-48 stepper motors to drive two axis laser pointer. The base is designed for stability and optional mounting. It also has a place to hold both of the UNL2003 stepper motor driver modules. # Print The parts are designed to be printed without supports. The base is printed upside down with only small bridging for the anchor tabs. TinkerCad Model: https://www.tinkercad.com/things/hdOUMt9kuLA # Build 1. A stepper motor is installed in the base with two M3 bolts and nuts. 2. The coupling attaches to the base stepper motor and the Laser Stepper Mount attaches to that. Both use M3 bolts and nuts. 3. The Laser Stepper motor mounts using two M3 bolts and nuts. 4. The LED Laser holder or Laser Pointer holder will mount to the top stepper. 5. The UNL2003 stepper motor drivers will mount with small M2 screws (or M3 bolts and nuts). 5. Arduino Code: I used the TinyStepper LaserGimbal example code to draw a simple circle on the wall with the laser: https://github.com/jasonacox/TinyStepper # Credit Thanks to mmontee for the great Bare Bones Gimbal mode. I used that great work as design inspiration for my model: https://www.thingiverse.com/thing:794786
