I used to have a raspberry pi that was running on a schedule to play rain noise while I was sleeping. When I moved I took it down and didn't put it back up, but never liked how excessive it felt.
So I built a simpler version that doesn't have a schedule but runs on an RP2040 and generates brown noise:
Will eventually add some key switches to it so I can start/stop it more easily (currently just plug it into USB when I want sound) adjust volume, low-pass filter params, etc.
