The DIY YAESU Rotator Controller (G1000DXC version) has withstood the test during the recently concluded 2025 CQWW SSB contest.One aspect is the hardware test.This version uses a 12V-5V DC-DC converter, and the power supply for the Arduino board is also 12V, relying solely on natural cooling without forced cooling. It has been running continuously for … Read more
The ARM Cortex-M series cores (M0, M0+, M3, M4, M7, M23, M33, M55, etc.) are based on the ARMv6-M or ARMv7-M or ARMv8-M architectures. They share a core 32-bit RISC design philosophy and the Thumb/Thumb-2 instruction set foundation, but there are significant differences in the supported instruction subsets, performance, features, and extensions.Different cores typically correspond … Read more
1. What is NPU? NPU (Neural Processing Unit) is a dedicated hardware accelerator specifically designed for neural network computations, with the primary goal of efficiently executing inference and training tasks for deep learning models. Unlike CPUs and GPUs, NPUs optimize matrix multiply-accumulate operations (MAC), activation functions, and quantization calculations through a customized architecture, significantly enhancing … Read more

LH replica VFC SIG MCXIntroduction to the original SIG MCX The SIG MCX is a series of carbines developed and produced by SIG Sauer, utilizing a short-stroke gas piston system improved from the SIG MPX submachine gun. It is available in both semi-automatic and selectable fire (assault rifle) configurations. Currently, it can fire 5.56×45mm NATO…
The barometer in your phone and the tire pressure monitoring system in your car are both powered by a “compact yet precise” MEMS pressure sensor. It operates based on the piezoresistive effect of silicon, measuring only in millimeters, yet it can accurately sense pressure changes. This design document from Wang Dajun’s team breaks down the … Read more
