Just got back for Don's house today with my German Marklin locomotive which need a way to convert 18 V AC to 12 V DC for a fan (I use it to keep the main electronics cool for out door G scale track). Don sat at his work bench (an impressive set up), and proceded to manufacture a component from various parts, installed it and bang! It worked as advertised! Being an Electrical Engineer, it doesn't surprise me that he can do this, but not charging me for it was something only good friends do for each other. Thanks Don! BTW, this man's time is worth a lot per hour, as he made his living (and a rather nice one from what I can see) custom building parts for government and private agencies.
