I want to share with you a little module I designed/made. It’s inspired after the telegraph machine Sam put in the museum. This module takes .txt files on an sd card and generates a Morse code gate signal. It has both internal and external clocks and a built-in clock divider.
I’ve uploaded some simple patch samples to the Facebook group. The possibilities are so much larger than Morse-like sounds. Morse code is intrinsically quite rythmic, so think of it as a pseudo-random gate generator.
The full schematic and Arduino firmware can be found here:
Hope you enjoy this and have fun with it!
