image: CWvox Prototype connected to the radio (Source: Kevin Loughin) These days, it seems like every speech-detection-related project is based on some kind of advanced algorithm, such as machine learning, pattern matching, or spectrum analysis. But Kevin Loughin (AKA KB9RLW), an amateur radio operator, built CWvox, a voice-activated keyer that uses the analog-to-digital converter (ADC) […]

Marko Pavlin has designed a Mini USB dongle with STM32F0xx that is connected to USB and controlled via command line interface. Mini USB dongle with STM32F0xx is suitable many for simple, mini projects. I attached speaker to Timer14 PWM output (Pin PA6) and LED (or optocoupler connected to PTT) to GPIO pin PA0 The provided […]
