Proficiency in sending and receiving Morse code — while no longer required for licensure — is the best way to experience traditional ham radio. Today, there are dozens of freely accessible websites and free or inexpensive apps for Android and iOS tablets and phones that provide sophisticated and efficient Morse code training. However, one of my favorites is the Morserino-32: a feature-packed microcontroller-based send and receive trainer, available from Willi Kraml OE1WKL for $99.
The whole Internet of Things (IoT) phenomenon has been around for a while now. But have you tried to create an IoT device on your own? If so, you know it’s not easy. However, it is now easier than ever as many of the manufacturers of IoT wireless chips and modules are providing the hardware and software to make an IoT device happen with minimum work. One example is the Wireless Xpress BGX13P module starter kit from Silicon Laboratories.
Rarely has there been as much interest in a high frequency radio as that shown to the Microbitx. Low power enthusiasts — better known as QRP operators as well as ham radio hobbyists — have rushed to place their order for this exciting and challenging new transceiver kit. Challenging in that it’s had a problematic chip “on its shoulders.”
A theremin is a musical instrument that is played by waving one’s hands in midair over the instrument itself. There is no physical contact between the player and the instrument. Of course, this makes playing a theremin very difficult. However, help is on the way! Enter the Altura theremin MIDI controller kit!
The Macchiato is a build-it-yourself/do-it-yourself (DIY) miniature eight-bit, polyphonic, digital music synthesizer kit. Derived squarely from the circuitry roots that are deeply entrenched in the pioneering work of American synthesizer maestro, John Simonton of PAiA fame and the legendary analog 1980s Pro-One synthesizer from Sequential Circuits, this offering from Zeppelin Design Labs is much more than just a kit.
It’s not all that often that a new piece of hardware comes along that immediately captures the attention of the builder community. The ESP8266 is the newest example of this. It’s only about the size of a nickel, yet contains a powerful 32-bit microcontroller and a Wi-Fi interface, plus you can buy it for around $4.
