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 […]

If you are interested in building your very own open source long-range remote control transmitter for your next project. You might be interested in a new video created by YouTube creator, electronics and robotics expert James Bruton this month. Showing his journey in building a DSM2 RC transmitter using the Arduino platform and hardware. Check out the video below to learn more about the process

If you have read my first blog on the topic, than you already know what I’m experimenting with. Low price FM Radio, build with TDA7088 / YD 9088. It was obvious, that technology from the early 90-x is outdated. I mean, simple “search and hold” function of the radio. Scan function works only one way, up in

After I finished my last project, I couldn’t stop thinking how to build an AM receiver, that would also operate in conjunction with my little friend Arduino. To minimize a workload and complexity, especially with RF part of the circuitry, I come up to conclusion, that SDR (Software Defined Radio) is the best choice for

What would you think about a program, made in the C language of the Arduino IDE, that makes the LoRa radio change frequency? This is what you will learn about in my video today, where you will learn about the differences between LoRa radio, LoRaWAN protocol, and encryption. We will then create a project featuring

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
