Hi Yaro,

Thanks for the kind words!

I also appreciate your dedication and experience as well! Kudos to both you and James for all your work with the zero force motor replications!
Sorry I missed the conference, but I intend to order the video of your presentation and most of the other videos as well.

After running and demonstrating the modified attraction motor several times, it unexpectedly blew the FET while I was showing it to my grandson. I replaced the FET and it blew again after a few more runs. Both times it blew was on start up under load after swapping batteries. So I went back to the MJL21194 and it runs with that, but not as well. I assume that's because of the higher impedance of the BJT type device. I probably wasn't driving the FET hard enough? Need to revisit the trigger circuit.

This replication was just to see if I could get results similar to what Peter got, and I was pleased with that. I have some ideas for a different design attraction motor I want to build from scratch using a multifilar coil like used in the SSG. More to come later. On vacation with my wife right now celebrating 50 years of marriage.
