@ Dreyfuss

Here is a circuit for it with the parts.

The + of the coil is the start of the coil and the - is the coil ending.
It says 750 turns but I think my coil is closer to 1000 turns.
A smaller coil will allso work fine.

Most or all the parts can be substituted for differant values.
This is just what I fund to work the best so far.

If your charging another big 12v battery the BEMF coming off the second coil winding would go to + on the charge battery.
Then the - for the charge battery can go to eather the - or + of the source battery.
I like to go - to - you get more power and current this way.
But it depends on your coil and setup if it will run that way.
If it stops when you hook up your charge battery this way.
Go - of charge battery to + of source battery.

Dont forget you allso need a small magnet to triger the reed switch.
Put the reed switch in front of your coil then put the small magnet by the reed switch to triger it.

The small magnet is used to make the contacts in the reed switch tutch togeather turning on the coil.
You may have to adjust the reed switch and magnet to get the speed and power you want.

Gonna make it and try it


thanks

Did it, and it works, Happy now, , made a couple of measures and seems that the current in draw battery is higher than in charger battery, the magnet and reed switches are changing with time so i need to readjust magnet position because the oscillation stops, some reed switches are getting lazy and have changed its magnet position to oscillate, maybe are just getting waste?

and one more thing..... in this circuit where would be the cable that when its taken off voltage comes up, it needs a cap? where would it be in this circuit?

thanks in advance

Good you have it going.

If you are talking about charging a capacitor it would just go in place of the battery.
Just be carefull it will fill up in voltage fast.

I did mean the circuit that lindmontor was trying and the cable he was removing to boost the voltage up, not sure which of these two attachments is the right one or if both are with cable on and off, but i dont have a clear idea for connecting both coils.


Thanks in advance

If you use the first one take the ignition coil and extra diode out.
So theres just one diode in between the transistor and capacitor.

This is a way to pull a little more power out of the system.
This allows you pull the wasted power off the reed switch.

When I hooked this up to my charge battery the battery went up to 13.5v from 10v as soon as it was hooked up.
Then droped back down slowly to 12.4 then started to rise back up.

The weird thing is when the charge battery started to rise in voltage so did my source battery.
The source battery went from 9.38 to 9.56 in about ten min.

I'll have to let it run a little longer and see if it starts to go back down or up higher yet.

After about two hours of running the source battery went way down in voltage.
To around eight volts but I allso noticed that the wire coming from the reed switch to the rectifier came unhooked some how.
So I'll have to charge it up a little and see if it will do it agine.

Interesting idea. I will give this one a try. I got those reed switches from Ebay that you recommended but they have not arrived yet in the mail. The weak reeds I get from Radio Shack don't last long. I have often wondered if maybe getting the energy right at the reed switch was something that has been overlooked. The Radio Shack reeds actually have a coil wrapped around the switch that I imagine are used in electronics to generate a signal for something.

@lidmotor

I'm still on the same reed switch the bigger ones work a lot better.
The one I'm using is a three amp reed switch but the one amp ones should work good allso.

I looked on ebay where I bought them but thats all I could find.
The bigger switches dont seem to stick at all.

I have remake the circuit a bit nicer and now it works with both batteries, if i disconnect the primary it keeps running with the charging battery, any idea of why could this be happening? or its just normal?

was the diode wasted, i got some ebay reed switches too, ummm well see who receives them, lol
anyway, the fastest reed switches make a cicle in 6 ms, 5 milliseconds close and 1 open, operations in those cases and in the lowest voltage are 300000000, so in less than a week they should get wasted or at least changing the working way, so i ordered some ne555 and ill make a stable with both waves same duration, and ill point it to the base of the transistor as reed switch does now, am i saying any stupid thing?

@ Dreyfuss

You would have to post the circuit your using.
If your using the circuit I posted you must have a wire crossed.
When the primarys disconected it should shut off and not run off the charge battery.

Sorry Slayer, it was the diode that was wasted, replaced it, and back running right, i made up a bit the last circuit you posted, and changed a couple of crosslines tell me if its right like that,

and thanks again for your support

Yes that looks right Dreyfuss

Thank you for cleaning it up.

I am trying out this circuit too, i really like its simple design.
Has anyone tried bistable reed-switches? As i understand it, they would not need an additional magnet?
In my very first results i have only seen a charge rate, if i have moved the magnet in my hand to a position, so that it was able to shake periodically. So i am not sure if just taping the magnet on the switches will have a continous effect?
The limited lifespan of the switches is a bummer.
An electrical switching would consume some power, so to use the magnetic field is probably the best idea. Stefan Hartman has used a relais in his shock charger.

Maybe im wrong, but according to the data sheet of reed switches, (http://www.meder.com/fileadmin/meder...Test_Data.pdf), typical number of operations are as much, close to 1000.000.000. If the fatest reed switch makes for example 1 ms per operation, this is the result of it´s self life

1000000000 typical nr of operations in best conditions
0,001 operation time
1000000000/1000= 1000000 total typical life in seconds
10000000/3600= 277,78 total typical life in hours
277,78/24= 11,57 total typical life in days


dont think is a bit time, correct me if im wrong in this aproach, if im right, i think that the best alternative is the NE555.

I tried the bridge rectifier at the reed switch and I liked how it worked. I also added a side CFL circuit and REALLY liked how that worked. Good job Slayer!! This thing really needs a voltage regulator and a charge controller to keep from over charging the charge battery.

@ Lidmotor

Very impressive video,thank you for taking your time to post it.

I'm anxious to figure out a way to control the charge power on the system. Does anyone have any ideas? What we don't want to do is lose any of this energy due to heat loss. Maybe if I get a large car battery as the receiver that would solve the problem. My little 5Ah batteries can't handle this high voltage.

@ Slayer---Did you have any problem with this?

Lidmotor

@Lidmotor

No if you use a big battery like a car battery or a marine battery.
It wont take a charge as near as fast.

I received my 1 amp reed switches in the mail that I got off Ebay and tried one out. I used the original 'rotorless pulse generator' circuit with no CFL and with just one transistor. I put the BEMF into my big cap with a 110v nightlight on it. In order to get the reed to work I had to put the small neo magnet on the reed itself. My coil was not strong enough to pull the switch open unless I did that. The interesting thing is that when I played around with that arrangement I was able to get the system to "pump" better. The voltage got up to as high as 120 volts with the nightlight on bright (did I make an inverter???). It ran at about an amp on 12 volts but everything handled it ok. These new reed switches work great but they are a little noisy.

@Lidmotor

LOL you dont need a radio to hear it.
Yes the biger reed switches are a little noiser.

Allso you can use a second magnet to fine tune it.
Once its running put the second magnet by the other end of the switch.
This way you can speed it up or slow it down without moving the reed switch.

@Slayer---Thanks for the tip about the second magnet trick. I'm still trying to figure out the best way to use the POWER coming out of my version of the circuit. I may try lighting up different kinds of 110v bulbs directly.

Lidmotor

This is one of the ways I use to charge small non rechargeable 9v batterys.
It can be used with 1.5v batterys allso.

I would like to try it with another 12v car battery but I dont have one right now to try it with.

Slayer007 how come yer up loaded files, when you click on the thumbnails the picture is so large. Mine allways open up not much larger than the thumbnail.

Sorry Beshires I dont know why it would do that.
When I click on it it comes up the right size.

You can allso add more that one battery.
I put four in series today and they all charged up in no time.

Ok I'll try that but I don't see how another battery will make my files larger.

A nice free program for many things other than looking at images is
IrfanView . One click (or keyboard) zoom in / zoom out.
Resizing images for saving and cropping , etc etc. views videos too.

Hi all,

Slayer and Lidmotor, most impressive work This circuit is very very interesting. I have a bedini wheel that works very nice and does what it says on the tin. I have been able to make my bedini trifilar coil self oscillate with ease so i thought i would mod my coil and the results look promissing with no reed switch. Im going to hook up a cap and ignition coil later to test. Basically, the triger coil makes the power coil oscillate and i then feed the radiant energy in to the third winding and out to a charging batt. My amp draw is 120ma and the voltage over the diode to charge batt is 14.8v. The way you are feeding the radiant output back in to the coil reminds me of Teslas bifilar patent. I'll report back later and tell you how it goes. Thanks again for showing us these circuits
