John K.'s S1GT

Hi All,

I Hope you all had a good Christmas. Unfortunately I came down with the flu on the first day of my holidays but managed to spare a few hours in the shed on my "S1GT".

I now have it running on some good deep cycle batteries, configured for 36V on the front and back end. I ran it all day. The front end settled into 36.7V whilst the back end would not get above 39.7V. The cap is now 13,600uF 50V and dumps in just under a second. After resting for an hour the primaries recovered to 37.0V whilst the secondary bank is at 39.2V.

The SCR is now triggered with a 1N4732 (4.7V 1W zener) in series with 2 x super bright LEDs which dumps at around 8V over the top of the battery voltage.

One very interesting observation - the shield on the main coil has been permanently magnetized and shows that it is a MONOPOLE South pole ALWAYS! I could only pick this up with my compass when I had the coil and the bonded shield on my bench away from any other magnets. Weird!!

Back to bed...

I cannot agree with that zener in forward bias mode. A zener in forward bias act like a normal diode with the forward bias voltage drop of about 0.7V.
So it should switch at 3V(led) +3V(led) + 0.7V(diode) +0.7V(scr bias) = 7.4V above battery voltage, which it does.
You can replace that zener with a normal diode and it should switch at the same voltage
If you now turn that zener around the circuit will switch at 3V +3V + 4.7V +0.7V = 11.4V above battery voltage.(47.4V). Your cap is rated 50V so it should be ok.
Could you please verify that for me
Cheers

Vissie,

You are right. I firstly had the Zener in forward bias mode. When I turned it around the SCR switched 4V higher. I will draw a schematic and try and get you accurate readings. I do remember that the cathode of the Zener is going to the anode of the SCR. When it was running on 12V, the cap was dumping at 21V.

Cap pulse on 3pole

Hi all, I have a new circuit on the back end for the secondary battery (Thanks John Bedini) actually its a new machine. One of the old 3 pole kits with the aluminium rotor. It is using (2) 15 MFD Caps (35V)
(2) 4.7 Zeniers, 220 resistor, SCR, 2 LEDS,( Pulses at about 4 seconds, caps charge to 23V but it charges) 1.2 amps+ using about 185ma on motor. What"s different I found is that I can use the energy (magnetic) from center coil top as I extended the rods and applied an coil running 12 G9 LED lights. It puts no load on the system like it does when coil is used directly off of the neos on the rotor. (Got something for nothing mabye?) I think from some of the work I do with John that maybe an solid state switch or a FET might be something we want to experment with on the secondary battery. Any way thats where I,m at on learing anout the BFW... so far. See video if you like.

Hi Chuck
Thats slick how you did the other coil for the leds, I'll have to try it.
Thanks

Chuck,

You should take the output and rectify it into a capacitor and see how much of a load that you can draw off the cap.

It has been my experience that LED's are somewhat of a piezoelectric effect where the LED's vibrate at the frequency that is visible to the naked eye. I've experimented with lighting LED's to almost full brightness where the power is only .09 watts (90V*.001A) driving 60 LED's. Power levels on LED's are deceiving in my opinion as it is more of a piezoelectric effect and less heat dissipation.

If you have some spare parts, you should make a new cap dump circuit and send the output of your "extra coil" it to a resistive load. After that, see if the rotor speed and/or input amperage maintains the previous levels.

Thanks,

Dave

Hi Chuck,
Is this connected similar to how Bits has placed his pickup coil:

http://www.energeticforum.com/renewa...tml#post117107

It looks like pictures are disappearing from the posts?

Anyway we did extensive testing on this a few years back – big thing to remember is that the coils are transformers and once you start adding on to the pole/core you run the risk of “robbing Peter to pay Paul”. At least that is what we did in all our testing. We could not find a way to get the energy out of the coil without affecting the other coil. We hope you are able to and show us how you did it.


@all,
On a positive note, we are back from “vacation” and finally have a couple of open days to do more testing w/ the bi-polar and 3PM kit. Last night we did some playing around w/ adding one coil on at a time while tuning. We flipped the polarity, advanced, and retarded the coils as part of the tuning. Wow! We fried/welded a couple of reeds on the MJL21194 cap dump ckt when we added the 3rd coil. (We’ve used this cap dump w/ 3 - 8filer coils – 24 transistors SG and not had the reeds light up like that. Hopefully we’ll be able to do some more thorough testing before school starts.

2nd coil on center coil

Thanks for all the great advice! One thing I found out the hard way last night after having the device running for about 24hrs... DO NOT STOP WHEEL WHILE HAVING PRIMARY BATTERY HOOKED UP AND MAGNET STOPPING ON CENTER COIL! IT BURNED UP MY ENERGIZER COIL. I was going to try to get a little more RMP from wheel (oops!) Well ill try that trick with the energizer as soon as I get another coil wrapped ( cap ). Also, I only had rods in coil projecting into it 1/2 way. Any more and I could here wheel start to slow down.

REED switch

@ minoly
You may want to get some hall switches. They are inexpensive and much more forgiving the way we are using them on our machines. I had a conversation with John on this a while back and he did not like the results he would get using reed switches. This has also been disscussed in previous posts.

Also, the coil I am using on the little 3pole (center) is #23 wire 750 turns.
The slaves are the stock coils. I really had to retard the timing after I installed it. it uses a little wheel with 3 magnets on timing wheel with hall. Reason i'm using this configuration is I did not wait for resin to dry in wheel and the Neo came flying out and took out one of the #23 wire slave coils.

clarification, we are using reed for capdump in combo w/ MJL21194.

we are using halls for triggering the energizer.

is anyone else playing around w/ all three coils at this point?
we are finding that there is a very small somewhat elusive window where the charging is best. and it's huge! we just need to nail down the the hall, our tape keeps slipping
if anyone else is using halls on the 3PM kit - we drilled holes into the fly-wheel and super glued some small neo's into it, we also taped some round ceramics to the face of the fly wheel, both seem to work well. anyone else using something different? many great posts since we've been away...

New cap dump circuit

@ web000x(Dave)

Good advice on replacing LEDS and using the extra coil for a different load!
Took an 80243c, (2) 4.7 zeners, 330ohm resistor, and (3)16v 470 MFD caps (took some time with different configurations), but was able to charge a 9v battery in about 20 minutes (was at 6.5v), then loaded it down with a resistor to about 8v and recharged to 10v(highest ever on that battery!)
I have an MJL1194 I may start playing with later...

@ all, thanks for all the great tips! this stuff is a lot of fun. well, have to go as we got about a 1.5' of snow in the last day

As always! Thanks John Bedini ! And EVERYONE!

6 foot wheel progress

Hello All,

We are SO EXCITED how our build is coming that we had to share the progress...

And when I say we, I am talking about myself and my business partner Scott or better known as (Txaggie00).

We completed one side of our 6' wheel today and hope to have the other side done by the end of the weekend. And if we're lucky we will have the A frame completed as well. We wanted to go much bigger, you know how we are in Texas, "Bigger is better," but we just didn't have anywhere to put it.

As you can see we took a similar approach to John B with our design. We had two templates (center circle and magnet holder) cut out of metal at a local water-jet shop so we could maintain a very tight tolerance. We then routered out the wood while using the same templates to use as guides to attach the spokes. This allowed us to have a very precise construction. All the raw materials have been purchased from Lowe's thus far...trying to keep it some what simple and inexpensive.

We have a lot yet to do and even more to learn! Looking forward to every moment


@Luther - Scott asked me to add to this post that he sent you a PM


Happy New Years, Brent

Miniature horizontal Energizer

This is my attempt to try what was done on the ferris wheel.
No surprises so far.
It is a 30 cm wheel mounted horizontal on a big pc fan.
Main coil 11 Ohm single strand. Slave coils 5.5 Ohms. Mounted with the offsets as prescribed. I have not tried the mag amp theory here.
The cap pulsar consist out off a 14 500 uF cap charged up to 24V before it gets dumped by a 7.5V zener, 3V bright led and a scr.
The timing and dwell is adjustable.
It draws about 300mA and dumps only every 4 seconds.
Bending the plate on the main coil does not really show any difference in performance.
I had to move the coils away as far as possible from the magnets otherwise it runs to fast and the SCR stays on. I am not sure if it will perform better at higher revs and will try the mosfet pulsar later to test at high revs as the fet pulsar has not got the switch off problem at high speed.
