There is nothing funnier than watching a Big Mouth Billy Bass narrate Richard Nixon's "Checkers Speech."

"Checkers Speech".

But man - this project is a long road. I'll record my efforts on this wiki as I link a big mouth billy bass to a Raspberry Pi.

This is essentially a robotics project and has three main parts:

  • Motors and Sensors
  • Control electronics
  • Control software

I'm not an expert on any of these three elements, so this continues to be a huge learning experience for me.

Motors and Sensors

The Big Mouth Billy Bass has three motors. Other versions of the bass have two motors.

Control Electronics

Obviously, this entire project is built around a Raspberry Pi and the RPi GPIO. However, the Raspberry Pi doesn't have any analog outputs or inputs, it isn't able to directly drive a motor and it isn't a good choice for real-time response. Any one of these three capabilities are going to require external electronics.

Fish motors are controlled with ... The mouth is controlled ... Speaking status is ... The Voltage meter is controlled with ... The webcam ...

Control Software
