...and we hoped this would become a reality a few years later.
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.，更多细节参见PDF资料

发布于“澎湃翻书党”的文章《从传统评点看｜凭什么武戏封神，又在哪断了脉络？》中，作者闫力元以毛宗岗评《三国演义》火攻剧情的“五色纷披，各成异彩”一句赞《镖人》的武打设计。闫认为，《镖人》深得“五色纷披”的精髓，片中有多场高密度动作戏，“却能让观众在相似的厮杀结构里，看到层层递进的变数与奇趣。每一次交锋，都严格针对人物的性格背景、武学传承，乃至于截然不同的地形与极端气候，进行了极具差异化的定制。”
