Hi all,

Lost post, new coil

3000 feet done, 1000feet to go. About 2-3 hours, with tape between each layer

w00t w00t!!! Thats quite the coil Max!
I'm going to look back through the thread for a pic of your mags...
What kinda pull strength and clearence do you have?
I'm uber excited to see it turning! I'm working on a new replica too...
Nothing to show yet, but I'll put pics up when I get it all put together.

Great build!

Hi all,

I'm still working shimming the neo's closer to the coil.
It's amazing on how much better it works as a generator the closer they are.
I'm on vacation till sunday. Still have 10 or more hours of work setting up the commutator. It will fire 10 to 60X per rotation. THAT'S THE KEY TO MAKE IT WORK.

10-60hz are just arbitrary numbers...
Think resonance... Think standing waves...
Test with a funcgen and scope to see it.
My plan is not to have multible on/off contacts,
but to have that built in to the driving circuit.
Looking really good! You're definitely on the right track.

I 've been also thinking about a mechanical/electrical hybird commutator with spark back feedback.
