EL Driver Shield

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

  • 2011-09-30: Started putting basic design ideas together.

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:
    • Outputs: HV converter sync pulse, 8x TRIAC gate outputs
    • Bus: I2C
