STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

Thanks Ossie for the axplanation

i now installed a 4.5 non rechargeable battery and put 2 resistor between the reed and diode (as Jean Louis Naudin did)

For my set up i used  57 ohms each  (47 + 10) and the RPM increase to 290

and now the trace is as on the attached picture.

As i have no schotky diodes i tried BY 550-800  seams quite good but will order some schotky next week.

I tried a lot of positions for the reed , and the best for my set up is as on the picture

I am making a long run test right now with the 4.5 volt battery

so stay tuned

regards

Ok got the V drops down to 0.02 an hour running at 2400RPMS. Not that much better than on the D cell really. I will let it run overnight. Are these numbers any good?

Jim,   nice work!  2400RPMS WOW!  Where did you get your Rotor?  Can you give us some specs on bearings etc.   Thanks.

Hi all

here it is full Mond. I don't know if it brings energy but the Ossbo is spinning its own weight, working against the bearing friction  and flapping  my air lab  still 10 hours from now

test begins at 12 00  with  (new normal cheap standard 4.5volt square battery non rechargeable)  at 4.8 volts and 290 rpm

interesting point    at 14.00 the rpm  was 294 and the voltage drop very slightly at 4.77   
                         at 16.00 the rpm  was 294 and the voltage drop very slightly at 4.75
                         at 19.00 the rpm  was 293 and the voltage drop very slightly at 4.72
                         at 20.00 the rpm  was 294 and the voltage drop very slightly at 4.71
                         at 22.00 the rpm  was 292 and the voltage drop very slightly at 4.70

the scope trace don't show any drop in the generative wave  (almost 5.6 volt very constant)  and the  power pulse is almost totally integrated in it  !!!

I will order tomorrow more sensible reed and schottky plus wind some more different coils  and we will see     

but anyway OSSIE YOU ARE GREAT   many thanks

regards

The rotor is just an old power supply fan that I increased the Dia of so I could fit my big mags on it. Uploading vid now. I had it has high as 7000RPM but it was not feeding back to the battery.
