Battery powered turntable with 28BYJ-48 stepper motor

thingiverse

A battery-powered turntable for painting or 3D scanning has been created. It features improved functionality with the addition of four bearings. The metal CY-8H 8mm Sliver Ball Transfer Bearing Unit plays a crucial role in this enhancement. Parts List: 1. An Arduino Pro Mini 5V 16 MHz board is used as the main controller. 2. A potentiometer with a 50 k value is used for precise control. 3. A button and switch are integrated for user interaction. 4. A LiPO battery charger/protection module ensures safe power management. 5. A LiPO 18650 battery and holder provide reliable energy storage. 6. The 28BYJ-48 stepper motor and driver board work together to achieve smooth motion control. 7. A knob is attached to the potentiometer for easy adjustment. 8. An RGB LED common cathode (optional) adds a touch of color and style. 9. A step-up boost inverter module 2A set to 5V powers the system efficiently. 10. A Piezo Buzzer 5V (optional) provides an additional auditory feedback feature. 11. One 150 Ohm resistor is used for precise voltage regulation. 12. Three 100 Ohm resistors are used for added flexibility in circuit design. 13. Wires connect all components together securely. 14. The 608z bearing adds stability and durability to the turntable. Tools: A hot silicone glue pen and double-sided adhesive tape are essential tools for assembly and repair. https://youtu.be/L_5wdH-oyDk https://youtu.be/vlyZ21LxB7A
