@All
Finally got my motor going right.
I'm using a fairly large 12 volt fan for my setup.
The fan was rated 7 watts at 12 volts.
For my setup I have a caduceus coil connected in series between the battery positive and the string of 4 diodes in the schematic.
But I am using only one 1000V  6A high speed diode in place of the 4 diodes.
Also the other single diode connected from the collector to positive is the same value 1000 V 6A diode.
I find the caduceus coil makes my motor spin faster for the same input current, also runs more stable.
I dug up an old 12 volt car battery.
After a long period of tweaking I got the motor to keep going at a slow steady speed.
It makes a nice chirping sound. 
The starting voltage was  6.92 volts. after 15 min. the voltage increased to 7.75 volts.
Will leave it running over night and see what it's at in the morning, hope it keeps going all night. 
Starting time here was 11:40 PM.

Very interesting!

The one with 3 leg is a IR Receiver so  if both came in the same package , the one with two leg is a IR Transmitter, not a led light.

That may be the case on some of them but we are talking blinking leds  there are also two leg blinking leds of various colors including rainbow . I have some three leg leds . they are two colors with one common . red and green . i also have some two color leds with two legs just reverse the voltage and get the other color . ac and you get both colors . It depends on what you are Buying as any led whether emitting or receiving blinking or tricolor can come in two or three legs .

One problem with these computer fan bedini motors is the fan blade. 
If we could build one of these without the fan blades that blow air we would have a lot more power
going back to the battery.
Right now most of the energy is wasted blowing that air around.
@plengo
Maybe the problem is you are stopping the fan from blowing freely with something blocking it.

I have tried Chopping off fan blades and left with a Knob. You loose the fly wheeling and there nothing to keep the momentum needed . now if we replace or cover the blades with a heaver solid piece of plastic that would work . . In My case i need the air to speed ratio ..


@Fasto . If you can Find a FLAT magnet . I use just one . it might cover 1/4 of the front surface . i dont use two and its only on one side . the ring magnet inside of these fans are very weak but the have a NS on them . I think My magnet is between NS . It sticks hard and there is no chance of it moving unless i push it really hard . Its less than 1/8 inch thick  .

A possible problem I can see using two batteries in series, is that I have found that when there is a difference in voltage between the batteries, one can rise in potential during discharge. I'm not saying that this is happening in your case but it is possible.

I have now reduced my fan speed as much as possible whilst remaining stable and I will monitor this over the next few hours. If I detect a drop in voltage I will then reposition my magnet. I'm using a flat hard disk magnet as per Gadget's suggestion. Once we can get our batteries charging it will be interesting to see how high the voltage will climb and whether it will stabilise at a certain level or eventually fall. Gadget reports that he can 'fry' his batteries so it will be exciting to see if we can get as advanced as him.

Hi Hoppy . I never said i Fried a Battery with a powersupplybedini I kind of think it might after a few months but i am running a jt on it now and have a happy point of staying charged and lights .  I did say I fried batteries with My Bedini ,the original one that the thread was started on . I cooked two so far and working on the third .(SLA) It puts out so much voltage and current it lights a 130 volt incandescent bulb and it charges itself .If i dont switch out with two knife switches ever three days and load it while charging they burn up .  I have not Fried any wet cells ever only sla . Now My 48 volt PowersupplyBedini Will Charge a Dead  (10volt) wet cell battery to over 13 volts in a days time . I have done this . But i have not cooked one and i don't intend to as i dont have any more to cook so i want to be careful .I stopped My Big Bedini . i only have three SLA battery left .I know i was drying it out when the voltage gets to 17 volts (ouch)
I am Glad you guys are seeing something strange . Its called OU I don't think you all would recognize it even if you are looking at it   I gave up trying to figure it out as why it works .Like i said before .I am happy with just using the extra power it makes and knowing i have Genuinely given you My Designs and results . I see you got it . But with all the test and stuff after you get it it messes it up . get it going set it in a corner for a few weeks and Build ya another one while its charging itself .If you find a flat magnet it will stay   Oh one more thing . It will adjust the sweet spot much better using two pots i can hit the spot anytime i want with the second one on there and neither of them are at  a full position . the second one offers full range from stopped to slow just above the charge point .
Best regards

This is so cool. I hope yours work and you can give us more details and pictures of your setup. Great work AbbaRue!!!
