How to prevent WiFi dropouts on ESP32 deep sleep wake cycles?
When waking from deep sleep, my ESP32 occasionally fails to reconnect to the router without a full hardware reset. Any recommended retry loop backoff?
Calibrating capacitive soil moisture sensor in saline water
Standard analog readings shift significantly when testing fertilized soil vs tap water. How do you normalize the ADC voltage levels?
OpenCV Haar cascade vs MobileNet SSD latency on Raspberry Pi 4
Benchmarked both on a 720p 30fps webcam feed. MobileNet SSD runs at ~12 FPS with quantized tflite models. Here are my memory profiling graphs.
