Recently, the microcontroller obtained a coil and conducted a coil induction experiment using ESP32 and Phyphox. Due to the small inductance of the coil, the induction phenomenon was not very obvious, but the technical solution has been validated. If a coil with more turns and an iron core can be obtained, the experimental effect should … Read more
Experimental Scenario 1 Introduction Recently, while reviewing exam papers, I encountered an innovative question based on photoresistors. Inspired by this, I decided to design a clever experiment using Phyphox and ESP32 to see if I could measure my own heart rate. 2 Design Idea Utilizing the combination of Phyphox and ESP32 to measure the resistance … Read more
Click the image to jump to the video! Here is the transcript ▼ Introduction Before the video starts, I want to ask, is your router placed in the corner of your room? If you don’t want to move it but still want to improve the overall Wi-Fi quality and enhance the signal in your room, … Read more
Since the birth of MCUs in the 1970s, the technology for breaking chips and the solutions to prevent chip cracking have been in a constant chase of “the higher the road, the higher the magic,” with each side trying to outdo the other. This article shares the development history of microcontrollers in terms of security … Read more
Conference Invitation Artificial Intelligence (AI) Chip Design Seminar (July 25, Beijing National Convention Center) A domestic startup specializing in AI FPGA acceleration algorithms, Deep Insight Technology, was acquired by the international giant Xilinx just two days ago, causing quite a stir in the industry. Currently, there are quite a number of companies in China working … Read more
Clock Design Solutions In complex FPGA designs, creating a clocking solution is a challenging task. Designers need to have a good grasp of the clock resources available in the target device and their limitations, understand the trade-offs between different design techniques, and possess a solid knowledge of a range of design practices. Incorrect designs or … Read more
When transitioning from concept to product, selecting a power supply is essential. An isolated power module provides 12V power for advanced ASICs, microcontrollers, FPGAs, and various other components. As always, these components practically fill the space on the circuit board, providing sufficient power, stability, thermal performance, low noise, and reliability, which challenge the laws of … Read more
This year marks the 57th anniversary of the Basic programming language. For many, their first experience with programming was in the 1970s to 1980s using Basic on Commodore PET, Sinclair ZX Spectrum, or Apple 2. Notably, Sister Mary Kenneth Keller, a member of the team that created the BASIC language, was the first woman in … Read more

This experiment uses a homemade voltage and current sensor. The sensor collects voltage and current values, displays them on the screen, and simultaneously sends them to a computer via Bluetooth for data processing. Through linear fitting tools, the resistance value is obtained, and the measured values are equal to the real values within an acceptable … Read more
