This will be a waterproof voice recorder. How hard could it be? I don't know, it'll use an SD card or something and have playback. So after the shower, I take it up to my office and transcribe my shower thoughts.
My enclosure arrived and is definitely big enough for the application. I also bought a MP3/MIDI/WAV/OGG play + record module with an SD card slot from adafruit. Hopefully the only other thing I need is a microphone, an SD card, and a speaker or an audio jack so I can play the files back without removing the SD card. Oh wait, the module comes with an audio jack.
