Older hackers will remember that a crystal set radio receiver was often one of the first projects attempted. Times have changed, but there’s still something magical about gathering invisible signals from the air and listening to the radio on a homemade receiver. [mircemk] has brought the idea right up to date by building an FM radio with …
A team of Researchers at Carnegie Mellon University’s Future Interfaces Group have developed self-powered radio tags called Sozu, which enables building-scale activity sensing, without the need for line-of-sight and at a very low cost. They claim a 99 percent detection rate and “almost no false positives.” The team of researchers includes Yang Zhang, Yasha Iravantchi, Haojian Jin, Swarun Kumar, and Chris Harrison. Sozu …

I love the look of old 1920’s radios. They are the embodiment of a decade. The radios that I like the most were vacuum tube cathedral radios made by Philco. When I think of old-timey radios those are the first thing that pops into my mind. So, I decided to make one using an old Arduino …
Hello Everyone!!! In this Instructable I am going to show you how I converted my (Commercial) RC drone that uses an RC radio system into a drone that is controlled by your Arduino using Bluetooth Why would I want to control my drone from an Arduino? I wanted to control my drone from an Arduino …

This time on the show we continue coverage of Toorcamp 2012 – the American Hacker Camp. This time Darren speaks with Rob Eby about packet radio as an extension of the Internet. Plus what could be better than flexible individually addressable RGB LED strips? %1 controlled by Arduino! All that and more!
This project is bases on the internet radio by Ed Smallenburg. He did an awesome job in creating a working internet-based radio. He shared his coding and hardware on the world wide web so that people like you and me can learn from it. He shared his build on GitHub using the copyleft license. (It …
This Instructable will show you how to build your own FM radio receiver shield to be used with an Arduino board. The radio chip we are going to be using is the AR1010 on a breakoutboard found at Sparkfun or Electrokit and there will be code to get you up and running provided later on. We are going …
Samsung Electronics Co. Ltd. has announced the Exynos 980 processor with an integrated 5G modem capable of download speeds of up to 2.55Gbps. report by Peter Clarke @ eenewsembedded.com The chip is designed in Samsung’s 8nm manufacturing process technology and the CPU has a six-two split little-big architecture divided between two 2.2GHz Cortex-A77 cores and six 1.8GHz Cortex-A55 …
I’ve not used an FM radio for years, but if you’d like to teach younger generations about older technology and show them how to solder components there’s an RDA5807 based kit that would allow you to build DIY FM Radio operating in the 87 MHz to 108 MHz range. The JC-300 kit comes with a …
FM radio transmitters and receivers are one of the projects that fascinated a lot of people and drove them to become makers. The lure of being able to deploy your own radio station, or build your own surveillance(-like) devices was what encouraged most of us to build our first fm transmitter or receiver. Nowadays, microcontrollers …

Arducon is an Arduino based ARDF transmitter controller specifically designed for for conducting amateur radio direction finding and is now available via Kickstarter. The unique piece of kit has been designed for active radio enthusiasts involved in the outdoor sport of Amateur Radio Direction Finding (ARDF). Backer early bird pledges are now available for the novel project …

Old radios didn’t have much in the way of smarts. But as digital synthesis became more common, radios often had as much digital electronics in them as RF circuits. The problem is that digital electronics get better and better every year, so what looked like high-tech one year is quaint the next. [IMSAI Guy] had …
