Re: dimensions of coil related to magnet

If you put an LED on the trigger (extend it via a cable) and then shine the
blinking light onto a white piece of tape attached to one of the magnets you
will have your answer. :)

and the scalar south poles in between for the trigger. am i right?

Yes, you want it in repulsion mode so it's pushing. I'm not experienced enough yet to advise you about big coils. I'll be doing my own experiments with those...

Andrew, 1. have that LED in series with a 330 ... 560 Ohm resistor 2. parallel to the place where You replaced the POT or parallel to the BJT (emitter and...

I'm still not sure about this coil i have. charging is taking too long (about 24 hours, when before I had about 10). I tried swapping the 2n transistor for...

By the way everyone, how many charge / discharge cycles are required to pass the BM3 testing process? Will a dozen cycles be acceptable? Preston...

Remember, your battery will take less time to charge each time you cycle it. This is part of the conditioning process. Mine started out taking 24 hours to...

my tuning is set to the first sweet spot on the pot with the lowest resistance (now about 88ohm with the mjl, drawing 150ma). there didn't seem to be any...

You should do a minimum 10 conditioning cycles and 20+ cycles for your spreadsheet, or untill your COP stabilizes. By the time you complete these your level of...

No need to get a new battery. It sounds like friction may be contributing to the slowness in charging and the lack of multiple sweet spots. We usualy measure...
