I have received a revision to the latest design, the FET was getting a bit hot when trying to drive a meter of EL wire.  So I added some metal to the layout to try to reduce the temp on it.  The temperature of the FET was too hot to keep my finger on it for more than 30 seconds.  I have built one it does work, and I am trying to optimize the Boost converter signal period on duty cycle to get the most power output while keeping the FETs temperature under control.
