How to Make a Custom Soundboard with the STM32F4 using FreeCAD -- Episode 568

Help! Our band needs a sound effect to be played, quickly and with minimal fuss. So why not make a custom box to be on hand for anytime a sound effect is needed. With an STM32 microcontroller and a speaker I set out to make a box to do just that.

I have built a couple of designs that do this function - both from MP3 player modules.

One was used in a robot for sound effects corresponding to various robotic functions.

One was used to interact and communicate with birds (designed for a researcher's thesis project)

Those both sound like cool projects, communicating with birds is an interesting idea/project
