There are plenty of “robot” projects out there that are really just a small remote control platform of some sort. We often like to think of robots of having some sort of autonomy though. [Luca Fagioli ...
A complete, reproducible walk-through of how a Ceihoit DVP-508 mini DVD player was made controllable from a Raspberry Pi without ever having its remote, and how a normal handheld remote was then ...
LPG is colourless and essentially odourless — the safety odorant added to it only works as a warning if someone is present, awake, and able to smell it. This project closes that awareness gap with a ...
Arduino Uno（ATmega328P）的 16MHz 主频下，最小定时器计数单位为 62.5ns，但其输入捕获寄存器无数字滤波配置，易受电源噪声干扰，实测对 38kHz 载波的占空比误差常达 ±15%；ESP32 虽主频高，但其 WiFi/BT 射频模块会周期性抢占 CPU，导致输入捕获中断延迟抖动超过 2μs——而 NEC 协议中“引导码低电平”标准宽度为 9ms，允许误差仅 ...
