The CWvox is a straightforward machine that converts voice instructions into Morse code keying

Whereas most of us affiliate Morse code with old-timey telegraphs, it’s nonetheless in use right this moment. The advantages now are the identical as they have been 100 and fifty years in the past: it’s an extremely resilient solution to encode info that works with quite a lot of completely different transmission strategies. However what when you have bother working a regular Morse code key? This CWvox device, designed by Kevin Loughin (AKA KB9RLW), interprets voice instructions into Morse code keying.

CWvox might be helpful for folks with disabilities and for individuals who have bother getting Morse code timing proper. Morse code depends on tone size to convey info and it isn’t all the time straightforward to carry a key for the correct period of time. CWvox takes care of that for you. Simply converse out loud both a “dah” sound or a “dit” sound at one thing near the proper timing. The machine will interpret these utterances after which output good keying.

The parts to make this work embody an Arduino Nano board, an audio enter jack, a small transistor amplifier, a potentiometer, an LED, and an output transistor. Customers can join a headset with a condenser microphone, which feeds into the audio jack to the amplifier after which to the Arduino. The Arduino analyzes the incoming audio sign to detect “dahs” and “dits,” then keys the radio utilizing the output transistor. The potentiometer lets the person regulate the sensitivity.
