Twitter to speech converter kit list
- Twitter app (here on iPad) to Internet
- Internet to PC running Processing sketch periodically scans for twets and strips message
- Processing converts to spoken output using tts.h text-to-speech library
- Speech played through audio amplifier
- Amplifier secondary speaker output connected to Arduino analog input
- Voltage detection in Arduino triggers output pulses on peaks
- Peaks switch power on and off, from model railway transformer connected to car door actuator motor
- Actuator moves jaw in time to speech peaks
