Learn to Send and Receive Morse Code with the Morserino-32

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.

Big Band Sound from the Palm of Your Hand

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.

Meet the ESP8266

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.
