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

  • 2011-10-02: Finished BOM/schematic for HV AC converter/inverter.
  • 2011-10-02: Finished designing/simulating HV DC generator in LTSpice, put BOM and schematic for this section together.
  • 2011-10-01: Many hours spent in LTSpice putting together a design for the HV DC generation.
  • 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: 1x HV DC converter sync pulse, 1x HV AC converter sync/polarity flip pulse, 8x optoTRIAC gate outputs
    • Bus: I2C
