Hi Gary,

It probably has quieted a little, but still very much in my mind. I bought
6 of Marks boards for the project, but the IGBT's I had on hand I decided
would be better to hold onto and go with Terry's IGBT's. However, right at
that time, stock when low and prices when way up. I've kind of been
waiting for them to go back down. I've just been so busy with things I
haven't had the time to get back to it.

However, it's still on the burner.

Take care,
Bart
