Hi everyone! 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. ![Schermafbeelding 2021-01-16 210340](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/d/dbe5b818cf8db07ff8409439164f653649355f8a.jpeg) ![Schermafbeelding 2021-01-16 210340_2](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/d/d7ee0c9fc11efc5f0ebcb000e39150df3f792ca1.png) I’ve uploaded some simple patch samples to the [Facebook group](https://www.facebook.com/groups/lmnc.projects.discussions.and.help/permalink/776566322952576/). 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: [https://github.com/TimMJN/Arduino-Morse-Gate-Generator](https://github.com/TimMJN/Arduino-Morse-Gate-Generator) Hope you enjoy this and have fun with it!

Oh thats genius! Now the little folk can tell Richard Branson to do one in their experemental music too 😛 ---

Which sd slot did you use? And do you literally put dots and dashes in the .txt file? ---

I used one of these: [https://www.amazon.com/Module-Storage-Adapter-Interface-Arduino/dp/B07PFDFPPC](https://www.amazon.com/Module-Storage-Adapter-Interface-Arduino/dp/B07PFDFPPC) Don’t know where you are shopping from, but they should be easy to find. Annd no! The translation into Morse is handled by the Arduino. The txt file can contain any text. Those samples I posted were excerpts from the bible! Holy smokes! ---

I think leaving the SD reader behind the panel will be the easiest way to handle it, and I think that will be totally ok for me. Thanks again for sharing man excited to play with it after my next JLC order ---

Definitely calls for a little easter egg in there! Mine says ‘telegraph’, but I’m sure you can come up with something! ---

This looks awesome! If you have any spares from the JLC order you’d be happy to part with I could be interested! It depends if there’s some kind of BOM though, as I am shite at reading schematics. 😃 ---

I was putting this together on stripboard and had a general question. ![20230311_090741](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/3X/a/a/aa4e546191035418322c870c3d6c14f8bca8ec59.jpeg) I got my power situation set up on the board (minus the L78L09), but when I measure the output of the L78L05 I get something like 11v. Is this because it is not under load? Am I missing something? [Next page](https://lookmumnocomputer.discourse.group/t/morse-code-module/2708.md?page=2)
