Hi Mike, I understand on your webpage explain how we could build own aircore instead of buying expensive from commerical and I believe it's very easy to make . Now I wonder do you happen to have any circuit diagram or theories in order for me to create circuit to get it working? Let me know if you could share out with me. Thanks

Hi Arthur,Thanks for the interest. I have been pulling a book together that covers three different technologies for simulating instruments. Air-core is one of the technologies. Air-core construction and both analog and digital circuits for driving it will be covered.My current focus these days seems to revolve around a bathroom remodelling project, so book progress has been slowed a bit. Realistically, it's probably several months away from press as yet.Mikewww.mikesflightdeck.comInfo for simpit builders.
