EL Driver 1
From Hackstrich
The EL Driver 1 will be an EL wire driver, that can be plugged into the EL Shield (revision 2+) and a future baseboard for standalone use.
- Generates 80VDC @ ~50-150mA from 3-15V in using the LT3575 IC
- Converts the 80VDC into 160v p-p using an H bridge
- H bridge is driven from a PIC10F microcontroller
- Can be set to low frequency, high frequency, or fed a pulse train from an external device
Status
- 2011-01-18: Assembled DC-DC section. Connected to 5V it pulls 250mA and outputs nothing. Troubleshooting needs to be done.
- 2011-12-04: Completed board layout, finished silkscreen, CAM files output and sent to Laen. Parts still need to be ordered.
- 2011-12-03: Completed 95% of board, 4 airwires left, then silkscreen/CAM.
- 2011-12-02: Completed schematic and BOM.
- 2011-12-01: Completed most of the schematic and BOM, LEDs still remaining to be done.
- 2011-11-30: Design of flyback converter based around LT3575 finalized. Started the schematic entry.
- 2011-11-29 and prior: LTspice simulations to finalize design.
