The EL Driver Shield will drive 8(?) channels of EL wire, generating required voltages on the shield itself. Each channel will support dimming individually.

Project Status

Ideas / Brainstorming

  • One single high voltage converter with separate switches for each channel
  • Dimming using a TRIAC on each channel like incandescent lights use
  • Shield will likely need a microcontroller on it
    • Inputs: Zero crossing input from high voltage converter
    • Outputs: 8x TRIAC gate outputs
    • Busses: I2C
