On October 14, 2025, the Liu Guanghui team from the Institute of Zoology, Chinese Academy of Sciences, published groundbreaking research in the prestigious journal Cell Stem Cell, confirming for the first time in primates that long-term oral intake of clinically safe doses of vitamin C can significantly delay and even reverse ovarian aging. This finding … Read more
Introduction Recently, I created a six-channel wireless metal detector transceiver, and it seems I’ve become interested in wireless control. In this issue, we will introduce the design and implementation of a ten-channel wireless relay controller. The project aims to achieve button control of ten relays. The relays selected are industrial relays with a rated coil … Read more
Several weeks after school, I built a small Arduino device. I wanted to move to the next step, and I needed a controller. I started looking for a controller that would allow me to choose what kind of signal to use, but I was unsuccessful. So, I made one myself. I have an NRF24L01+ module, … Read more
1. Introduction to EESkill NRF24L01 Wireless Module NRF24L01 is a wireless communication chip recently produced by NORDIC, using FSK modulation and integrating NORDIC’s own Enhanced ShortBurst protocol. It can achieve point-to-point or 1-to-6 wireless communication.The wireless communication speed can reach 2M (bps).NORDIC provides the GERBER files for the communication module, which can be directly processed … Read more
