Not possible. I have only three output pins and the other two are in use. :-( > Otherwise, look for the smallest MOSFET that will handle your current, > as smaller size usually means smaller leakage current.

That was exactly what I was missing. I'll take a look at the 2N7002T more carefully in the morning. thx, Jason. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
