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: Zero crossing input from high voltage converter
  • Outputs: 8x TRIAC gate outputs
  • Busses: I2C
