Measure the mass of an eyelash with a DIY microbalance
推荐理由
YouTube just dug up a a real nice breakdown that Ben Krasnow did
说明
这是2014年由Applied Science发布的一部演示,主题归在Embedded systems & DIY electronics。它讲的是diy microbalance这一支里的具体问题,而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成:Ben Krasnow of Applied Science builds a DIY microbalance from an analog panel meter with an optical servo loop. It reaches about 5 micrograms of precision and is used to weigh a single eyelash at around 35 micrograms.这些读者给出的理由,核心是:Pointed to as proof that you can weigh micrograms cheaply at home, and as a clear breakdown of how such a scale works.讲法不绑某一条新闻,过几年仍然可以当材料看。从2018年到2026年,有1位不同的读者在1个不同月份把它推荐出来,其中明确叫别人去看的有0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diy microbalance变成能跟着复述的例子。
