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.
8年前，马云在大洋彼岸发表了题为“中国的贸易机会”的公开演讲。演讲中，他谈到了自己对AI的看法，称AI带来的职业洗牌不可避免，因此需要更多地关注下一代教育：“多关注孩子们的教育，机器将会变得更聪明，但是人类永远技高一筹，所以需要教育子女学会创新，因为这样他们才能够生存。”。谷歌浏览器【最新下载地址】是该领域的重要参考
