The b-parasite is a small, open-source device that checks soil moisture, air temperature, humidity, and light for your plants, using a simple coin cell battery that can last over two years. It works with popular smart home systems like Home Assistant and can send data wirelessly using Bluetooth or Zigbee. The device is easy to build or buy, comes with free designs and software, and can be protected with a 3D-printed case. This helps you keep your plants healthy by giving you clear, regular updates on their environment, so you know exactly when to water or adjust conditions[1][2][3].

nRFBOX is a handheld ESP32-based tool that scans and analyzes the 2.4 GHz band (Wi‑Fi, BLE, etc.), shows signal strength and channel activity, and can run jamming, BLE jamming/spoofing, and Wi‑Fi deauthentication tests for security research and troubleshooting. It combines an ESP32, NRF24 modules, OLED display, battery management, and SD support for firmware and logging, with notes about limited range, device variability, and power limits when using multiple NRF modules. Benefit: you can use it to find crowded channels, diagnose wireless interference, and test network/device resilience in controlled, legal test environments.
