Imagine you own a weather station. Then imagine that after some years have passed, you’ve had to replace one of the sensors multiple times. Your new problem is that the …read more Continue reading Recreating Unobtainium Weather Station Sensors
A common criticism we hear of cyberdecks is that functionality too often takes a backseat to aesthetics — in other words, they might look awesome, but they aren’t the kind …read more Continue reading The Vecdec Cyberdeck is More than a Pretty Case
Sometimes you need to create a satellite navigation tracking device that communicates via a low-power mesh network. [Powerfeatherdev] was in just that situation, and they whipped up a particularly compact …read more Continue reading Tiny LoRa GPS Node Relies on ESP32
What do you get when you cross WiFi and LoRa? Researchers in China have been doing this, and they call the result WiLo. They claim to get reliable connections over …read more Continue reading WiFi Meets LoRa for Long Range
Meshtastic is a way to build mesh networks using LoRa that is independent of cell towers, hot spots or traditional repeaters. It stands to reason that with an SDR and …read more Continue reading Decoding Meshtastic with GNU Radio
Stay in the amateur radio hobby long enough and you might end up with quite a collection of antennas. With privileges that almost extend from DC to daylight, one antenna …read more Continue reading Passive Diplexer Makes One Antenna Act Like Two
In the past few years we’ve seen the rise of low-power mesh networking devices for everything from IoT devices, weather stations, and even off-grid communications networks. These radio modules are …read more Continue reading A Long-Range Meshtastic Relay
A LoRa project has traditionally required a dedicated radio module, because it’s a commercially licenced protocol. But as the way it works has been progressively reverse engineered, it’s become ever …read more Continue reading LoRA, With No Radio
RNode is an open source, unrestricted digital radio transceiver based on — but not limited to — the Reticulum cryptographic networking stack. It is another interesting project in what we …read more Continue reading RNODE: A Portable Unrestricted Digital Radio
The range of hardware that comes on some dev boards these days is truly staggering. Those little LoRa boards are a prime example — ESP32 with WiFi and Bluetooth, a …read more Continue reading Custom Library Rescues Good LoRa Hardware from Bad Firmware
