For those of us who remember Radio Shack as more than just an overpriced cell phone store, a lot of the nostalgia for the retailer boils down to the brands on offer. Remember the Realistic line of hi-fi and stereo gear? How about Archer brand tools and parts? Patrolman scanners, Micronta test instruments, and don’t […]

We know what you’re thinking: with so many wireless modules available for just pennies, trying to create a physical data link using ultrasonic transducers like [Damian Bonicatto] did for a short-range, low-bitrate remote monitoring setup seems like a waste of time. And granted, there are a ton of simple RF protocols you can just throw at a

In the world of drones and hobby rockets, Niklas Bommersbach is making waves with his innovative safety system. Bommersbach has designed a system that detects critical flight behavior in drones, rockets and other aerial vehicles, activating a two-stage parachute deployment for a safe and controlled descent. At the heart of the system is an Arduino Nano microcontroller that monitors
Awesome parachute system saves drones and rockets Continue Reading
Low-power radios, often referred to in the amateur radio community as QRP radios, have experienced a resurgence in popularity lately. Blame it on certain parts of the hobby become more popular, like Parks on the Air (POTA) or Summits on the Air (SOTA). These are events where a radio operator operates off-grid at remote parks
OFF-GRID RADIO ALSO REPAIRABLE OFF-GRID Continue Reading
Simon Kemper has published a guide for making use of the low-cost Dragino LGT-92 LoRaWAN asset tracking system to help track a bike when it’s stolen for easy recovery, while running for years on a single battery. Dragino LGT-92 is built for asset tracking across a LoRaWAN connection (a long-range low-power radio standard). The Dragino LGT-92 integrates a LoRaWAN radio with GPS-based location tracking. For
