I’ve done some work with Arduino controlled cars, but the ones I’ve worked on have always been slow and methodical. This is great when learning arduino, but I wanted something a bit more…fun. Enter the RC car. RC cars are literally designed to be as fun to drive as possible – they’re toys! I went […]

Hi guys, my name is Pedro Castelani and I’m bringing you my first instructable: building a two way radio with arduino for, well, whatever you need it for. In this project, we will make two seperate circuits which will act as both reciever and transmitter. The most important components are two arduino boards (all of

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive. That’s good enough for AM radio, anyway, but you’ll need to try this DIY FM receiver if you want to listen to something more

Morse code unit for kids. Variable speed and different levels. My son goes to CUBS and has a special event coming up. This event is all about communicating with other Scouts/Cubs from around the world? Via radio, also over the weekend there will be other activities including Morse code. So this little project is just

More than once, we’ve looked at a cool board like the TTGO T-Display and thought, “What can we build with this?” If you are [Volos Projects], the answer is a tiny Internet radio. He’s done a lot of other projects with the board including some games and a weather station. You can see the project in

Over on the Spectrum web site, [Dale] — a relatively new ham radio operator — talks about his system for sending text messaging over VHF radios called HamMessenger. Of course, hams send messages all the time using a variety of protocols, but [Dale] wanted a self-contained and portable unit with a keyboard, screen, and a GPS
ARDUINO + HAM RADIO = TEXTING Continue Reading
When Pete Juliano sat down to design a sideband transceiver for the 20 Meter (14 MHz) ham radio band, he eschewed the popular circuits that make up so many designs, opting instead for the innovative approach of the Seven-Transistor Novelty. He forged ahead, building a novel design that he calls Pete’s Simple Seven SSB Transceiver,
PSSST! HERE’S A NOVEL SSB RADIO DESIGN WITH ONLY SEVEN TRANSISTORS Continue Reading
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

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
Arducon Arduino based radio ARDF transmitter controller Continue Reading
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
