We don’t usually speculate on the true identity of the hackers behind these projects, but when [TN666]’s accoustic drone-detector crossed our desk with the name “Batear”, we couldn’t help but wonder– is that you, Bruce? On the other hand, with a BOM consisting entirely of one ESP32-S3 and an ICS-43434 I2S microphone, this isn’t exactly going to require the Wayne fortune to pull off. Indeed, [TN666...
The strongest version of this narrative highlights a clever, low-cost solution to drone detection that prioritizes privacy and accessibility. By leveraging historical acoustic detection methods and lightweight algorithms, [TN666] avoids the pitfalls of cloud dependency and high costs, making the technology democratized and resilient. The Goertzel filter approach is elegant, efficient, and aligns with the principle of edge computing—processing data locally rather than relying on external servers....
