Years ago, people figured out Raspberry Pi’s can accidentally double as FM radio transmitters without a need for any radio front-end (if we don’t count a single jumper wire working as an antenna). They achieved this by tying a GPIO pin to a software-controlled clock around 100 MHz to modulate audio. This created a low-powered FM radio transmitter. Due to the pin producing a square wave instead of a neat sine wave, it also emitted weaker harmonics at 300MHz, 500MHz, etc., but any basic FM radio could pick up the audio. I wondered if a similar feat could be achieved by much less powerful Raspberry Pi Pico microcontrollers.

社会科学有一个概念叫古德哈特定律（Goodhart’s Law）：当一个指标变成目标时，它就不再是一个好的指标。「请」和「谢谢」的出现频率原本可以作为服务友好度的一个粗略信号，但一旦它变成员工被考核的 KPI，员工就会优化这个指标本身，而不是优化它背后的东西。。关于这个话题，夫子提供了深入分析
