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. https://github.com/cifertech/nRFBox

🌍 Over 2,200 years ago, the Greek mathematician Eratosthenes calculated Earth’s circumference using only a stick and his brain — and he was almost exactly right! 📏 By observing shadows in two cities, he calculated the Earth was about 40,000 km around. Ancient genius at its finest! [Source] @googlefactss#AncientGreece#ScienceHistory#Eratosthenes#EarthCircumference#AncientScience
