Most of the parts are on order from Aliexpress and should arrive in 30 to 50 days. In the meantime, I will be developing and testing the active band pass filter and envelope detector circuits. I also received ten 35mm piezo diaphragms this week. I will be using them to create several DIY hydrophones so I can start taking underwater audio recordings of boats.
