Drilling is the most expensive and time-consuming process in PCB manufacturing. The PCB drilling process must be implemented carefully, as even small errors can lead to significant losses. The drilling process is the most critical process in PCB manufacturing. It forms the basis for the connection between through-holes and different layers, making drilling techniques very … Read more

Abstract: This paper designs an intelligent warehouse item sorting robot that can adapt to various terrains. The robot’s structure consists of a shock-absorbing operating system, a six-degree-of-freedom robotic arm, and a mechanical gripper; the control system is composed of a QR code, Arduino, tracking module, servo control module, motor drive module, ultrasonic module, servos, and … Read more
MAKER: indoorgeek / Translated by: 趣无尽 Using a digital tube to display time is quite common. We have also introduced projects that use mechanical devices to construct and display numbers, such as this “pure mechanical device simulating a digital clock”. This one is slightly more complex, and enthusiasts have expressed that it is quite challenging. … Read more

DIY Simple Mechanical Arm with Arduino Introduction The mechanical arm consists of Arduino, servos, and MeArm hardware. The Arduino controls the servos through programming, enabling the functionality of the mechanical arm. There are two types of servos: analog servos and digital servos. Digital servos (Digital Servo) and analog servos (Analog Servo) are fundamentally the same … Read more
