Omega + ethernet + wifi + Class D Audio Amplifier = DIY Musiccast speaker
"Smoke me a kipper, I'll be back before the morn."
-- said the RAF pilot who never returned...
Pretty simple to say it out loud, I want to use my existing passive stereo speakers from the 20th century incorporating Onion components (CPU, wifi, ethernet) with a stereo component like the Adafruit MAX9744 (or, one from parts-express) into a franken-cast speaker.
Basically, the easiest way to make a speaker work with Musiccast is to connect the speaker to the network through ethernet, connect it to the app, change the connection to wireless, then disconnect from ethernet.
I know how to create bluetooth speakers but I have all these nice Onion components lying around collecting dust, so...
- Make sure I can replicate https://onion.io/2bt-omega-i2s-audio/
- Create the circuitry to dry run it on a breadboard with small throwaway speakers
- Create a 3D printer internal case for the speaker cabinet
- Solder everything up and hope it works?
