A few days ago, a frustrating problem left me quite unhappy.The final solution was simple, but the problem itself had me deep in thought. I thought it was time to tidy up the messy breadboard circuit, as all the issues began at that point. (Note: These circuits are mainly used to drive my Cunning Chronograph). … Read more
The piezoelectric trigger switch circuit described here is a microcontroller-compatible impact sensor switch module operating on a 5V DC power supply. The entire circuit can be assembled on a standard 5×7 cm circuit board. The piezoelectric ceramic element (Pz1) can also be easily mounted on the PCB. This module provides a “logic” (H) output when … Read more

From the creation log, this project started at the end of 2018 and has been updated intermittently until a couple of days ago. An interesting project that took a long … Read more
Abstract: In response to the application demands for high-precision indoor autonomous navigation and positioning for pedestrians, a wearable human motion measurement device prototype integrating Arduino and the Xsens Awinda inertial measurement suite has been designed. This system is easy to wear and highly reliable, achieving synchronous measurement of dual-foot IMU information and foot distance, supporting … Read more
A long time ago, in Denmark, there was a king named Harald Blatand, who unified the constantly quarreling tribes of Denmark into a complete nation. The king had a nickname called “blátǫnn,” which translates to Bluetooth in English. In ancient Nordic runes, the initials of the king’s name ‘H’ and ‘B’ are written differently than … Read more
PCB Network News Sharing an interesting piece of information: using wire to create a “circuit board”. I hope it inspires colleagues in the industry. What is Freeduino? It is an Arduino UNO board without any circuit board. It interconnects components using a technique called freeform, utilizing wires or copper instead of a circuit board. It … Read more
This article is sourced from “Invention and Innovation” March 2024 issue At home, my mom often can’t find her phone. Every time, I have to use the search function on my dad’s phone to locate her phone and make it sound. Whenever she can’t find the TV remote, she always says, “If only the remote … Read more
“ Simulation is one of the most important tools in the process of robot learning and research, which refers to the technology of simulating actual physical systems through computers. Robot simulation is based on interactive computer graphics technology and robotics theory, generating geometric shapes of robots and displaying them in 3D, used to describe the … Read more
The ultrasonic sonar is a device that measures the distance to an object by emitting sound waves at a frequency above the human hearing threshold (typically above 20KHz). Its working principle involves sending out sound waves and measuring the time it takes for the sound waves to bounce back after hitting an object. By calculating … Read more
