Описание: This short video clip follow my building of a simple Morse Code practice oscillator using the NE555 timer chip. It incorporated a practice push-button (not ideal for practice, but a nice addition). A Morse key can also be connected across the same solder pads. I didn't use a loudspeaker but included a 3.5mm stereo socket to facilitate the use of stereo headphones. The two outputs are wired in series with the ground tag of the socked left disconnected. Headphones were used in the demonstration clips. I hope you enjoy the video. de Tony Breathnach (EI5EM).
