Jonny:

I have a question on the coil for Bedini.  I have the three pack of mag wire from Radio Shack.  (22,26 and 30 ga.)  There is not enough of any 2 sizes of wire to make a good size coil.  Can I solder one end of one wire to the other to make it longer?  Then I can go buy another pack of wire and use 2 spools of the 2 sizes.

Lidmotor used mixed sizes in some way and said he was getting a type of transformer effect somehow.

Also, I was thinking about winding a trifilar coil using 3 sizes of wire and just not using the 2 ends of the 3rd winding right away.  Do you think this would hurt the coil?

Sorry for all of the questions.  I guess I could just try it and see but, if someone else has already tried and it does not work, it would save me time and materials.  Thanks.

Bill

@Pirate.Hi Bill,thanks for the Your kind comments.Regarding your Bedini build,I can't see a problem soldering two spools together if of the same gauge,others have done it sucessfully just pay attention to insulating the joint,nail varnish should do the job.If Lidmotor has done it with different gauges and reported interesting results then that too is worthy off further investigation,i have not personally done this.
  The coil i have had good results with is two 250gram spools off 26swg wire  wound bifilar giving me 1:1.
(I was thinking off transformer action when i decided on using the same gauge for both trigger and power.).I know Bedini uses different gauges but i wanted to try something different,who knows what you might discover if we stray from a well troden path?
My next coil will be three 250g spools off 28swg wound trifilar.I think it would be a good idea to wind your coil trifilar as it gives more recovery options and i don,t think it will be detrimental to your Bedini motor performance,it will give you a lot more options for trigger and power circuits.Another tip i can give you is to put plenty off adjustment for tuning in the base circuit.I use a 20k variable,a 1k variable and a fixed 100ohm resistor.If i can be off any more help just ask. ;D

@Jonnydavro
Nice experiments.

@Bill
Can I solder one end of one wire to the other to make it longer?

When splicing wires for coils, solder and then wrap with a good few wraps of tape for physical protection. If you don´t do this then you run the risk of the sharp edges of the cut ends wearing through the laquer of adjacent coils over time, if that coil is in the higher or lower stand then you end up shorting a full stand or more.

Jonny:

Thank you for your answers.  Yes, you got exactly what I was thinking about with the third wire in the wind....for possible later use and experimentation.  It will save me from having to make another coil later on.

I got a response to my question on Lidmotor's video on youtube about how he wound his small coil.  I understand better now.  He used the same RS kit for wire I have and wound all of the 26 ga. and all of the 30 ga.  The transformer parts comes into play because the wire spools are of different lengths so he has more of the thinner wire than the thicker.  He says it works better than expected and is interesting.  He did not solder them together like I first thought.

I appreciate your advice and offer of future help...I will probably need it.  Good suggestion on the additional resistance adjustment capability.  I will do it like you suggest.  My rotor is from an old VCR spindle and turns very freely so we will see if I can get this thing built in the next few days or so.

Thanks again.                    Great topic you have here!

@all:

Issue: The blocking oscillator in the joule thief circuit is resonating in the kHz / gHz range, ..how does this translate to pulses; will there be some sort of frequency divider?

Hi.Today i made a USB Joule thief Bedini motor which charges a 12v battery from the usb port on my laptop.I can think off plenty off other things that could be run in this fashion.Here is what i have up to now.Here is a video off it running.

@Jadaro.Sorry i can't help with your question.

Jonny:

Excellent work with the USP source!  This will be very helpful to a lot of folks.

I just completed my Bedini tonight. (I started it about 6 months ago)  It works although I found that my magnets are facing south out instead of north.  One thing I noted was that, when I went to smoke a cigarette, I disconnected the power battery (I am using 9 volt nicads) the motor was still turning at a very high rpm and continued to run.  I left it like this for about 5 minutes and then disconnected the charging battery and it stopped.  Do all Bedini motors do this?

If I want to increase my rpm (I am guessing it is about 6,000 or so) if I add a second coil like you did, do I used the same transistor?  Or, do I make another separate circuit?  If I do make another circuit, how are these synced? Or, do you wire the transistors in the Darlington fashion?

Sorry for all of the questions but, I know, from your work, you have the answers.  Thanks.

Bill

Hi Bill.Great that you have finished your Bedini,can't wait to see some pics.
Regarding North or south facing magnets.I find both orientations work well as long as the polarity off the coil is correct,yours obviously is as it is spinning so good.
Adding a slave coil is fairly straight forward.You do need another transistor,1 resistor and 2 diodes.The transistor and slave coil are wired in parallel with the power winding off your bifilar coil and 1st transistor and you use the same value resistor that you have used on your first transistors base on the 2nd transistors base and connect to the variable and put a diode from emitter to base the same as in the first transistor..Ive sent you a pm with a drawing.
Regarding your motor continuing to run after you have removed the run battery is not normal for a Bedini.It is in fact what we all seek.Could you have removed the charge battery instead off the run battery?
Was the neon lit when the motor was running minus the run battery?
Try it again Bill as i can see no way that the charge battery could run the motor as per Berdini's schematic.You never know you may have discovered something already ;D
I  think your going to enjoy experimenting and modifying your Bedini and i can't wait to see what you are going to do with your joule thief and maybe fuji  as you are light years ahead off me with this.I am still using my first joule thief and i am trying to find a clear step by step off marks mk2 so i can take the next step.If i can be off anymore help just ask Bill.
        Kind regards jonnydavro

Here is my newest video of the Bedini replication.  I am using lead acid batteries this time.

Here is another video I shot today.

http://www.youtube.com/watch?v=2W0kOQAkYDc

Nothing much different except that it has been running and running......and now my charging battery is almost up to 13 volts. (12.9)  With the run battery at only 12.4 volts, if this is linear then is it bad if my charge battery goes up to like 15 volts?  Also, when I touch the positive lead (output) where it connects to the charging battery and also happen to be touching the metal framework I used, which is for a heat sink and tied to the transistor collector, I get a pretty good shock.  I am guessing it is in the neighborhood of over 400 volts as it feels the same as my shocks from the Fuji JT circuit.  I have tried but can't measure this on any of my meters but, I know it is there as I can feel it. (trust me on this)  Is this energy that is being wasted?  Or, is this the high voltages spikes that are going into the charge battery but can't be picked up by my meter because of the high frequency?

Sorry for all of these questions but, I am sure you have been through all of this before.  if there is ever anything I can do to help you, just let me know.  Thanks.

Bill

Hi Bill.Your battery will be fully charged when it reaches 13.8v.You can boil a battery if you over charge it for a prolonged period so i would swap them at 13.8v
.At 12.4v  a lead acid batteries plates will start to sulphate so thats something else to think about and at11.9 it will be considered discharged.
Have you considered making a battery swapper?The daftman has generously posted his circuit on youtube and i posted a link to this in jesus's thread.It is a voltage sensing swapper so it would be ideal for swapping your batteries,something to consider anyway.
Regarding your shocks.This will be the spikes they just prefer to go via you when you become part off the circuit and you will need a scope to see them but not to feel them ;D..I have only been shocked when i was pulsing a transformer with the output so lidmotors coil sounds like a good choice.The fact that you can actually get a shock from your output is a good thing as like you suspected you will be generating large spikes and this brings us back to sulphation as from what you say i think your motor will be good for recovering old sulphated batteries,your new one's won't be to affected by this yet so your not getting the full benefit from the spikes, i personally would be trying to charge an old car or drill battery which has sat in a draw for a year.
If i can be off any more help just ask Bill as we are all in this together.

@ Jonny:

Thank you for the information.  That is exactly what I needed to know.  I am at about 13.5 today so far on the charge battery so I will be switching them soon.

Yes, I have seen some great work on the switching circuit used by Daftman...excellent work.  In the future, I will probably try to do that as well.  I do have some old batteries from a cordless drill that only hold their charge for about 3 minutes or so which makes them near useless in the drill so maybe I can try reconditioning them on my Bedini and see what happens.  They really can't get any worse, ha ha.  I will keep a close eye on them while doing so as they may like the charging or they may not.

Thanks again Jonny.

   If thoes batteries are Nickle-hydride or L-ion, I would be very careful. I did a set of Nimhi in that way.
I had to take them outside for fear they would explode on me. They are very finiky on how they charge.
Nicads do well with  bedini.

Thanks.  Yes I have read the same thing in several places.  I have not pulled them out of the drill yet but that is good advice to try it outside anyway.  Its not like we need an extension cord right? Ha ha.

Good news...I just pulled one out and they are Nicads.  They are very old and just about worn out so I may do it outside just to be on the safe side.  Thanks for mentioning this.  Safety is important.
