At this point it’s pretty well-known that you can tack a long wire to the Raspberry Pi’s GPIO, install some software, and you’ve got yourself the worlds easiest pirate FM radio station. We say that it’s a “pirate” station because, despite being ridiculously easy to do, broadcasting on these frequencies without a license is illegal. […]
At what age did you begin learning about electronics? What was the state of the art available to you at the time and what kinds of things were you building? For each reader these answers can be wildly different. Our technology advances so quickly that each successive generation has a profoundly different learning experience. This […]
Temperature is a delicate thing. Our bodies have acclimated to a tight comfort band, so it is no wonder that we want to measure and control it accurately. Plus, heating and cooling are expensive. Measuring a single point in a dwelling may not be enough, especially if there are multiple controlled environments like a terrarium, […]

Amateur radio is an extremely broad church when it comes to the numerous different activities that it covers. Most of the stories featuring radio amateurs that we cover here have involved home-made radios, but that represents a surprisingly small subset of licence holders. One activity that captivates many operators is grid square collecting. The map […]
It wasn’t long ago that you needed to know Morse code to be a ham radio operator. That requirement has gone in most places, but code is still useful and many hams use it, especially hams that like to hack. Now, hams are using the Raspberry Pi to receive highly readable Morse code using very […]
While Mars is currently under close scrutiny by NASA and other space agencies, there is still a lot of exploring to do here on Earth. But if you would like to explore a corner of our own planet in the same way NASA that explores Mars, it’s possible to send your own rover to a […]
If you own one of the ubiquitous RTL-SDR software defined radio receivers derived from a USB digital TV receiver, one of the first things you may have done with it was to snoop on wide frequency bands using the waterfall view present in most SDR software. Since the VHF and UHF bands the RTL covers […]
“When all else fails, there’s ham radio.” With Hurricane Harvey just wrapping up, and Irma queued up to clobber Florida this weekend, hams are gearing up to pitch in with disaster communications for areas that won’t have any communications infrastructure left. And the perfect thing for the ham on the go is this ham shack […]
[Chris D] noticed that the excellent software defined radio (SDR) software gqrx will run on the Raspberry Pi now. So he married a Raspberry Pi 3, a touchscreen, an RTL-SDR dongle, and an upconverter to make a very nice receiver setup. You can see the receiver in action below. The video is a little light […]
The Raspberry Pi Foundation has released an experimental version of its Linux-based Pixel OS for Windows and Mac PCs. The OS, originally designed to run only on the Raspberry Pi hobby board, comes with the Chromium web browser and a suite of productivity and coding tools. “We asked ourselves one simple question: If we like […]
An amateur radio repeater used to be a complex assemblage of equipment that would easily fill a 19″ rack. There would be a receiver and a separate transmitter, usually repurposed from commercial units, a home-made logic unit with a microprocessor to keep an eye on everything, and a hefty set of filters to stop the transmitter output […]
Everyone pays close attention to the weather, but for those who live where tornadoes are prevalent, watching the sky can be a matter of life and death. When the difference between making it to a shelter or getting caught in the open can be a matter of seconds, it might make sense to build an […]
We see a lot of old radio restoration projects around here, and we have to admit to having mixed emotions about some of them. It seems a shame to go through the effort to lovingly restore a vintage Art Deco case only to stuff it with a Raspberry Pi and Bluetooth. Seems like if you’re […]
The things Hackaday readers come up with and post over on Hackaday.io never cease to amaze us. If you’ve never checked it out, be careful — you can easily spend hours (or weeks) of your life just skimming through the projects that have been logged there. Many of the builds use modern development tools like […]
