One of the interesting experiments you can do at home with fast fourier transform algorithm (FFT) is figuring out level of water in your domestic water tank by analysing sound frequencies generated by the water going into the tank when filling. you can easily put some sort of microphone on your tap to hear that sound, considering the microphone is sensitive enough. and then by analysing sound spectrum, you can possibly tell a difference between full and empty tank as sound changes throughout the process of filling. just saying.🤔
@mohtashimnizamani I finished reading Sapiens to the semi-feral kitties last night and we began Homo Deus. I look forward to reading to them and they seem to expect it.
