Demonstration of a small motion detection script I wrote for the picamera. This video was recorded before any optimizations were done to the script. Each image is captured at 64x36 then compared to the previous image pixel for pixel based on their RGB value. As I come up with ways to make the script better I will push the changes to GitHub.

Add a WiFi camera module to your LiteWing ESP32 drone for real-time aerial video streaming. Step-by-step wiring, mobile setup, and troubleshooting guide for hobbyists.

Build a dual NRF24L01 ESP32 Bluetooth jammer from scratch. Full circuit diagram, pin connections, firmware flashing & video demo. Educational RF project for makers & engineers.

This AWS can capture data on air pressure, temperature, rainfall, and soil and air humidity. Once you have the components in hand, assembling your station is simply a question of wiring everything together as shown in the project’s instructions. And then, downloading the Arduino included sketch.

I’ll try to show you how I turned your typical Raspberry Pi, combined with some cheap components and IP Cameras, into a state-of-the-art home monitoring system capable of recording video, turning power outlets on or off and sensing movement.
