Hi Tinman,
  FYI - I'm apparently getting blocked from going on your forum at http://iaec.forumco.com by my ISP... It's a little complicated - my router has half-failed, and I can only access interchat by this 'OpenFON' functionality it has, that's still working. OpenFON is a public wifi network - and uses 'Cleanfeed' filtering (I believe). It seems to be blocking all of forumco.com.

Hopefully should be getting a new router today that will fix the problem. Thought you might be interested to know forumco.com seems blocked by some networks in the UK though...

Hi Tim
Yes i am aware that some(very few)block forumco,and other site's. We have had a few members with the same problem,one most recently from ireland. The simple fix is,just call your isp and ask them to unblock the site-it has worked every time so far.

Anyway,another test done,with the stator coil conected in series with the rotor-as per norm. Seems we can still draw from the stator coil,without effecting the P/in-infact,once again dropping it.

Some things i have noticed with the series conection,using rectified AC

1-the current draw is lower-ofcourse.
2-the output obtainable from the stator coil is a lot lower.
3-the RPM's are a lot lower
4-Odly(and im not sure why yet)the torque is lower,unlike i stated in the video???.

Same test using smooth DC,by adding large caps to the FWBR.

1-Power consumption go's way up-almost double.
2-Cannot draw enough power of the stator coil to run the same LED.
3-RPM slightly higher-maybe 200RPM.
4-Torque about the same-but just a rough guess.
5-motor sounds like it's doing some welding-its not happy at all.
This may be due to the change i made to the brushes-but unknow.

Now i believe it's time we had a load placed on the RT's output shaft,and begin some testing on P/in and P/out from the generator.
I will be using an 80 series fisher and pykle smart drive for the generator.
