The Wow! signal is a famous, strong, and unexplained radio signal detected in 1977 by the Big Ear radio telescope in Ohio, lasting 72 seconds and appearing to originate from the constellation Sagittarius. Its origin remains unknown, with some speculating that it could be an extraterrestrial technosignature. Upon reviewing the signal data, Astronomer Jerry R. […]| rtl-sdr.com
You won’t find another networking niche where seeing the energy on the medium is so important, nor will you find handier all-in-one highly portable Wi-Fi tools than those from NetAlly. When y…| wirednot
For various reasons, I’ve found myself bumping into LoRaWAN as a wireless networking construct over the last couple of years. If you’re not familiar, this is IoT-oriented low power, long range (sometimes), low bandwidth kind of stuff that integrates with the larger connected world if needed via Ethernet, Wi-Fi or cellular backhaul.

I was hanging out at Eagle Creek Reservoir near Indianapolis, doing some birding. I had my beloved Canon 90D set up with a big lens and I was waiting for anything interesting to fly over as I stood on the deck looking out over the water. Out of nowhere this huge clap of thunder sounded, […]| wirednot
