While most of us associate Morse code with old-fashioned telegraphs, it is still in use today. The benefits now are the same as they were 150 years ago: it is a very flexible way to encode information that can work with various transmission methods. But what if you have trouble using standard Morse code? This CWvox device, designed by Kevin Loughin (also known as KB9RLW), converts voice commands into Morse code keying.
CWvox may be useful for people with disabilities and those who cannot properly master the timing of Morse code.Morse code relies on the length of tones to convey information, but maintaining proper timing is not always easy.CWvox will handle these issues for you. Just say the sounds “dah” or “dit” out loud at the right time. The device will interpret these words and then output perfect keying.
The components that achieve this functionality includeArduino Nano board, audio input jack, small transistor amplifier, potentiometer, LED and output transistor. Users can connect headphones to a capacitive microphone, which connects to the amplifier via the audio jack, and then connects to the Arduino. The Arduino analyzes the incoming audio signal to detect “dahs” and “dit,” then uses the output transistor to key the radio. The potentiometer allows users to adjust the sensitivity.

Received an invitation from the editor of Hunan Science and Technology Publishing House, and soon received the new book from the publisher Mark Labbe, translated by Cai Liqin and Yin Qian, Scientist Biography Series:“Guglielmo Marconi: The Man Who Connected the World”, during the May Day holiday at home reading, the complete life puzzle of my childhood idol, the father of radio Marconi, was pieced together in my mind: a person who was obsessed with researching radio throughout his life, the first person to put the radio spectrum into practical commercial use, the first person to successfully develop a global communication system, a person whose passionate pursuit of radio neglected other things in life, a gifted individual who was deeply devoted to science, even without formal education or a diploma, he was nominated for the first Nobel Prize in Physics at the age of 27, and won the award eight years later. At the turn of the 20th century, his name was practically synonymous with radio, we need to understand him in that era.
The Marconi I had previously encountered was fragmented, mostly about his successful transatlantic radio communication experiment with his assistant on the British coast in 1897 and the subsequent commercialization applications, which were highly technical and not very readable. Searching online, there is limited content about Marconi, and a few articles are not enough to understand the life of this radio genius. This book presents a panoramic view of Marconi’s complex life under the halo of fame, brave, and despicable, as the author of the book said, Marconi’s greatest invention is himself.
“Guglielmo Marconi: The Man Who Connected the World”, [Canada] Mark Labbe/Author Cai Liqin Yin Qian/Translator, Hunan Science and Technology Publishing House, December 2021 edition
This book “Guglielmo Marconi: The Man Who Connected the World” reviews his legendary life, and also adds unpublished archives and field investigation materials from four countries and various languages. The author wants to tell us that Marconi’s life and achievements do not only belong to Italy, his imagination and inventions transcend time, and today’s world and we still live in his creations.
