We have liftoff. My first Balloon Environmental Sensing test successfully “slipped the surly bonds of earth, and danced the skies on laughter-silvered wings” sending data back the whole time. First flight was at the Digital Naturalism Conference in Gamboa, Panama, featuring 10+ sensor values streaming from the balloon to an online data collection system and dashboard. It was a big success! …

Last month we did range testing on a new LoRaWAN radio network installation in Gamboa, Panama. The network, which covers the entire center of town is part of the Digital Naturalism Lab’s commitment to supporting wildlife and environmental research. Gamboa, where the Smithsonian Tropical Research Institute’s laboratory is located, is surrounded by the Soberanía National Park, a large, intact tropical forest …

Maybe you’ve struggled with coding for time zones, local calendars or historical time changes. Or perhaps you’ve wondered why a software developer went pale when you asked them to add local time calculations to an app and wondered why? In this classic review, Tom Scott explains how a seemingly simple measurement calculation becomes a “twisty-turny thing” that takes software developers down …

I’ve been writing hands-on examples for using MicroPython on XBee radios. MicroPython is an open-source programming language based on Python 3, modified to fit on small devices, and optimized for microcontrollers. By using MicroPython, an easy-to-learn scripting and programming language, you can rapidly prototype intelligent behaviors at the edges of your network. Cryptic sensor readings can be transformed into useful data, excess transmissions …
