Horrific USB power supply fault. (Electrocution risk.)
推荐理由
He earned my respect from a video on a USB charger with an electrocution risk
说明
这是2016年由bigclivedotcom发布的一部演示,主题归在Repair, teardowns & right to repair。它讲的是usb charger safety这一支里的具体问题,而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成:Electronics hobbyist bigclivedotcom tears down a cheap USB power supply with a manufacturing fault that carries full mains voltage to the USB ports, showing the risk of electric shock.这些读者给出的理由,核心是:Cited in threads about cheap chargers as proof of why proper certified and isolated power supplies are worth paying for.讲法不绑某一条新闻,过几年仍然可以当材料看。从2016年到2024年,有2位不同的读者在2个不同月份把它推荐出来,其中明确叫别人去看的有1次。适合先看结果再决定要不要深挖的人。先看它做成了什么。如果已经会了基本定义,就把注意力放在它怎么把usb charger safety变成能跟着复述的例子。
