Show HN: BotWave – A simple way of playing with FM using Raspberry Pi devices

Hi HN!

I'm the author and maintainer of BotWave, a piece of software that lets people owning a Raspberry Pi (Zero to 4) broadcast on FM radio over a relatively small range. It also supports building a network of Raspberry Pis connected to a central server to manage them all.

Disclaimer: I already know that Raspberry Pis produce a ton of harmonics, and that broadcasting on FM may be illegal depending on your country. It is not meant to be misused.

PS: I already posted about it about 8 months ago, but since then it has become significantly more powerful, documented, and upgraded.
