Raspberry Pi spins precision movement stage for beautiful up-close microchip videos
Robert Elder’s precision movement stage project, utilizing the Raspberry Pi, is aimed at achieving precise and controlled rotations, particularly for capturing close-up shots of microchips. The inspiration for this project came from Elder’s need to highlight microchips on a larger scale for his YouTube channel, RobertElderSoftware.
In the project, a Raspberry Pi 3 B+ is employed, although it is not directly connected to the motor; instead, it interfaces with an Arduino. Elder opted for this approach to create a modular setup, providing flexibility as he can easily swap out Arduino boards as required.
The main objective of the project is to enable a motor to achieve full, continuous 360-degree rotation. Gears attached to belts are rotated by the motor, which in turn rotates the plate holding the microchip. A camera positioned above the plate captures dynamic close-up shots as the chip moves beneath it.
Despite the impressive functionality of the project, Elder notes that it is still a work in progress. He acknowledges the presence of some shakiness in the construction, which requires further optimization to better suit his workflow. Nonetheless, the project demonstrates the Raspberry Pi’s versatility in precision movement applications and showcases its potential for creating customized solutions tailored to specific needs.
