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, 3x HV AC converter control pulse, 8x optoTRIAC gate outputs
- Bus: I2C
