One of my birthday presents this year was two 900MHz Adafruit feather M0 LoRa 900MHz boards. I hadn’t had a chance to try them out but just before going on holiday I realised that our destination in the Alps might provide a nice testing ground (or mountain) so added them to my hold luggage.
The post is amazing in that he had a transmitter in a chalet in the valley and took a receiver on a cable car up the mountain – and it worked (out the window due to the metal car acting as a bit of a Faraday Cage).
Even on flat ground, with trees and buildings in the way, I was still able to exchange packets at 2.60km, and after that point I rounded the edge of the opposite mountain which probably blocked any further data.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
