He hasn't responded to emails or anything. I've redrawn an IC schematic to have some made.... the cheapest cost per unit is around $2 each (no ICs, just the board) and that's buying 66 of them for something like $116 shipped. I've held off ordering them for two reasons though... one the 4551 ICs seem to be a little troublesome to locate at the moment, and two because thesteve has designed a better single IC design that can also be made switchless if desired. I'm thinking I may draw up that design instead. I'll let everyone know when it happens though!
