Hey Kone,

I have not much experience with how batteries behave. I figured out that what the meter displays as batteries voltage is always just relative. Depends on the load and will change with increased or decreased load. So a short moment where batteries voltage is increasing temporarily does not prove much. Also when I was charging the battery while running the motor from grid the voltage went up quite quickly. But when running from battery after that it was dropping quickly again as well. To be sure you have to run it for a long time I guess. Then you might cross the perfect level as you described it as well.

The latter you are saying is what Romero has hinted to is one way to go. But as I see it and as you are saying, we need a second cap for that. How did he do that with just one?

Hi Chal

Well its another way to go for looper with two caps as I described - but romero "could of" done this if he wanted to...he had enough power to dump anywhere...
I think he pulsed what he put into into his motor coils (and/or what he took out of his motor coils via backemf/recoil) THROUGH the string of generator coils like described about a week ago which is what Nolan in video is doing - this is why Romerp had such high draw going into its motor-coil circuit when operaiong OU, and why he had such high votlage coming out of those little coils....anywasy thats my theory for now on it...

anyways I was just saying you might want to instead of charging batery, put that power into cap, and run 2nd motor coil circuit as another way to go if you get discouraged charging batteries - only good way to tell charge on batteris (lead acids) is to use a hydrometer with the floating balls to check actual charge...or else long-term tests with load which take forever to do....

Today I turned the rotor of my contraption upside down. The singing coil is still oscillating when the rotor magnet (north down, was south down before) passes by.

The other news which I am excited about is that I wound another coil and I got a second ringing coil now. It behaves like the first one but a little better. It is is bifilar coil that can be used unifilar or bifilar. It seems that it is oscillating at a higher frequency above the audible range. When it is oscillating like that it does consume considerably less current (just 0.15A, even when constantly oscillating by placing the hall above the coil) than the first coil (1-2A) but at more than 60V peak to peak . Now when I add a parallel cap, the frequency drops (like I have learned from the first coil) into the audible range and then the coil sucks a lot more current (2A). Have to see how quick it is at charging a cap.


Update: Just measured the voltage DC through FWBR: 40V! 60V is what scope shows AC side. So I wonder if this could be optimized with better diodes.

Update#2: Unfortunately the amp draw increases with a load and the oscillations will be audible as well.

Hi all!

Not much happening here so i want to share this with you. I'm still playing with bemf and constanly improving efficency (i think). I'm not trying to generate power but making the driving unit more efficent. My testing rotor is made from 8 HD one in top of another with really small magnets that are placed at the edge of the disks.
In the picture below there are 3 cases:
1- normal driving
2- driving circuit with recycling bemf
3- driving circuit with recycling bemf but different connection

In the right side there is the curent consumed from a car battery
Those 3 little black-white coils are in parallel and spin the disk from bemf.

Hey Marius

I had done the same thing a while back, using the discharge of the first drive coil to run a second and collected from that into a battery.  ;]  Cool stuff.
