Has anyone seen Lasersabers new motor runs on 1000uf cap

I have a hunch and am wondering if you can try to put the reed between coils 3 and 4 and remove the power feed and try it cold turkey like @LS is doing?

Since we know that inductors discharge at disconnection and capacitors discharge at connection, what I am thinking is that putting the reed at the end of the series coils as you have it now then in series with the cap is not giving enough inductive recharge to the capacitor since the reed is blocking one side of the capacitor. But putting the reed at coils 3 and 4 will ensure that both inductor sides will discharge into the cap at disconnection.

Conrad:

Wow!  That is a great looking rotor and coil assembly you have over there.  All built the old fashioned way too.  Very nice work...and fast too.  I wish you the best of luck with your replication.

Either I am missing it or we still dont have number of turns for the coils. Maybe since we have the dimensions of the bobbins, we are to just fill them to the rim. Fill one while counting turns then make duplicates. Maybe the difficulty mentioned of these is that the wire is 46awg and the printed bobbins have imperfections that the wire catches on while winding. Not sure.

Well with those figures in mind I suppose an inductor calculator can be used to come up with inductance approximately. Im interested in these numbers and resistance.

Im still bungled by the diode in series with the coil, reed and cap. I would think that once the cap is charged to max potential of generation, that it would stop working.
I really dont want to be a party pooper. But in my mind, especially with the introduction of that diode in a circuit that all parts are in series, the only way I can imagine it to run like it does is that there must be another source. Even without the diode, a source would work, but the diode has me stumbled. Unless the voltages beat the diode into free passes through the back door. 

Then the only other possibility is that all the windings in series, if the total length of wire is very very long, long enough for there to be large potential differences between far ends(delays, phase relationships) then maybe there is some bounce or say lopsided compression from one end of the total length of wire to the other.  Then again, the thing runs at different speeds producing different freq at each rpm level.  Idunno.

Driving me nuts already.

Was that 42 awg?

[Magluvin]

oops  yep  42 awg.   Kinda like splittin hairs.
