Technology Connections 带大家解构传统非电子老式电饭煲的机械奥秘：利用居里点（Curie point）巧妙触发磁铁与弹簧开关，在极简朴素的家电构造中完美融合了热力学与磁学原理。
为什么 HN 推它
绝佳展现“非智能家电里藏着大智慧”的趣味硬核拆解，也是入坑该频道不可错过的代表作。
「之前完全没想到老式电饭煲居然这么聪明，把热力学和磁学物理机制结合得如此巧妙。」HN 网友原话：I had no idea they were so clever, combining thermodynamics and the physics of magnetism.
英文原摘要（HackerTube / Claude 整理）
Technology Connections explains how old-fashioned non-electronic rice cookers work, using a magnet and spring switch tripped by the Curie point. It shows the thermodynamics and magnetism behind a simple appliance.
HN recommends it as a delightful breakdown of the cleverness in dumb appliances and an entry point to the channel.
