Join us on Wednesday, September 18 at noon Pacific for the Software Defined Radio Hack Chat with Corrosive!
If you’ve been into hobby electronics for even a short time, chances are you’ve got at least one software-defined radio lying around. From the cheap dongles originally intended to watch digital TV
It’s a staple of our community’s work, to make electronic devices do things their manufacturers never intended for them. Analogue synthesisers using CMOS logic chips for example, or microcontrollers that bitbang Ethernet packets without MAC hardware. One of the most fascinating corners of this field comes in the form of …read more

Radios are, by and large, not powered by steam. One could make the argument that much of our municipal electricity supply does come via steam turbines, but that might be drawing a long bow. Regardless, steampunk remains a popular and attractive aesthetic, and it’s the one that [Christine] selected for …read more

Fast radio bursts (FRBs) are one of the most intriguing mysteries of modern astronomy. Picked up from all corners of the cosmos, these perplexing radio signals usually only last milliseconds before fading forever, but some particularly strang… Continue reading Eight new repeating radio signals detected from deep space
The meaning of the word portable has changed a bit over the years. These days something has to be pretty tiny to be considered truly portable, but in the 1940s, anything with a handle on it that you could lift with one hand might be counted as portable electronics. Zenith …read more
In about five billion years’ time, the Sun will grow into a red giant, probably swallowing the Earth and putting an end to any and all life that’s still kicking then. As this material is shed off, the Sun itself will become a small, dim, whit… Continue reading Astronomers hope to search for radio waves broadcast from dead planets orbiting dead stars
Statistically, it’s pretty much a given that alien life is out there somewhere, whether that’s Martian microbes or highly intelligent life beaming comms through the cosmos. While the Curiosity rover is poking around in the dirt for the former… Continue reading Powerful new telescope joins the search for possible laser pulses from aliens
