As a weekend project with the goal to build a birthday present for someone that wants to be disturbing corporate meetings with classic soundbytes eg. slide whistle, airhorn, drumroll etc. It is powered by an 18650 and has an amp and speaker builtin.
By wiring 8 arcade style buttons with builtin LED's to a teensy 4 equipped with an audio hat. Storing files named 1 - 8.wav in 16 bit/41Khz format to an SD card formatted as FAT. The filenames correspond to the buttons so 1.wav is triggered by button 1, 2.wav by the second button so on and so forth.
This is my first public repo, you can create an issue but chance is big I will not be adressing it. Don't let this stop you from reaching out if you have questions, just don't expect me to maintain this repository.
