STM32F103RE 3 Axis CNC v1
Mackey Oct 10,2024
See my Instructable for a full implementation example here.All end stops, stepper driver fault lines, and buttons have their own external interrupt.The Step pins of all four 8825 stepper drivers are PWM timer pins. As noted in the GitHub ReadMe file, PWM is used in one-shot mode to set the pulse width of the stepper pulse NOT the frequency of the pulses. This is because the step frequency is variable, it ramps up then down during a move. The one-shot pulse width offloads the pulse duration to ha...

Arduino 3D Printed self Balancing Cube
Pavleski Oct 10,2024
 Self-balancing devices are electronic devices that use sensors and motors to keep themselves balanced while in use. They uses gyroscopic sensors and accelerometers to detect the movement of the balanced object and adjust the speed and direction of the wheels accordingly, allowing to control the device through shifts in their weight. This time I will present you a project in which the balanced object is a 3D printed plastic cube, inside which the reaction wheels and control electronics...
