I haven't seen the book, and so we may be at crossed purposes. I am thinking in terms of the pamphlet which shows a relatively simple set up. Seeing the pulses on the two channels would be very useful.

Hi wrtner,
Thanks for the link. The copy I have contains pretty much what your book does with the exception that there is an extra section following the book which gives some additional circuit description. After that Tom Beardon is let loose.

I seem to recall John Bedini stating that although one might design spectacular coil arrangements for the "Energiser", the basic model still works well: or words to a similar effect. So I have followed the original design. I used a relatively large diameter wheel so as to enhance the peripheral effect of the magnets speeding across the coils; greater change and all that. I believe Watson used seven magnets and eight coils. I believe that he also rectified each coil separately, I have the coils running in series, as that is how I read the original construction details. I suppose it might be of little difference. Assuming that each of the wave peaks is clipped, then other than the angle offset of the asymmetrical magnet arrangement, there is still a lot of pulses flowing to the tank capacitor storage. Therefore if my machine is doing about 1100 RPM that gives 8800 clips per minute. Or approximately 147 pulses a second.

Looked at from the speed perspective this is not a fast acting pulse generator! However, and this is where I am failing somewhat. If I were able to capitalise on that frequency then I should be up there with the gods. That is why I am redesigning the circuit so that I can control the interacting pulse rates. Also, this approach will I think allow switching at the correct point so as to optimise the charge and discharge of the tank to minimise the current flowing from the battery and edge towards self excitation. Not beyond the bounds of impossibility. With the relays I think I am loosing too much of the inherent design efficiency in the switching time. Also these are extremely difficult to synchronise, which is ok for a set speed, but, slippage comes in if there is any deviation of frequency.

I am awaiting the delivery of some components. Hopefully, I should be up and running by next Wednesday: Friday at the latest I hope.

Cheers

Dwane

Commutator Mod

Hi,
I have modified the FEG as per recommendation of Mr Bedini in his booklet. I have found that this change has provided an new intellectual challenge. Clearly, to get this FEG operating requires some thought. It is relatively easy to synchronise the brushes with the switching of the capacitor charge/discharge and motor runtime. However, my coils are not providing sufficient "energy" to maintain the momentum of the flywheel. The situation is worse than when I at least had it running off the relays and a timing circuit. So either I need a counter to enable a sufficient charge time for the Cap, or I need to rewind my coils to provide a low impedance load - get more current through.

It is easy to see why people have not persevered with this machine. every change requires some engineering cost or material cost of some sort of a wander towards the precipice of the unknown. More so a problem when there is no clear horizon of information to illustrate if I am heading in the right direction. It is no wonder that for some people there might be some skepticism as to the validity of the information provided suggesting a simple device!

A lesser mortal might give up. But as I have invested time and energy and money I'll persevere for a little longer. The concept of "Tinkering" is the wrong choice of verb to describe the challenge of getting this thing going.

cheers

Dwane

You need coils of sufficient size. It might pay you to look at Ron Pugh, page 6:

http://www.free-energy-info.com/Chapter6.pdf

There might be more precise constructional details.

Hi wrtner,
Thanks for the clarity, And there was me thinking that this FEG was a different sort of beast to that of the SG circuit. I suppose it could be made to be by using a magnetic pulse motor that I am working on, to be directly driven from the pulse action of the Rotor magnets. I can also see now why you questioned my use of the neodymium magnets. I'll have to look around for some ceramic magnets. Otherwise the switching circuit could be swamped if I am to use the SG mod.

This switching must have been the error that John Bedini discovered regarding the Kromrey Convertor. However, I still have to get my head around the comments made by John Bedini regarding the simplicity of using a commutator and the motor run pulses and the capacitor storage which are not part of the SG circuitry. I think a rev counter activation to simulate the switching system might work. Incidentally, I have wound some low impedance coils for greater current production and will fit these this weekend to measure their response.

Thanks and cheers

Dwane

I see them all as cousins.

What are you using for a core? Very important to use a material that takes on magnetism quickly and sheds it equally quickly. I think JB still suggests R45 or R60 welding rods. (Some people go on about magnetite, black sand, but this might be a red herring).

Soft Iron cores

Hi there wrtner,
my apologies for the delay in replyin. I have attached a couple of "development" photos. Mostly self explanatory. I have rewound the coils trifilar 20 guage so as ro capitalise on my tank storage and the opportunity to create a low impedance source. I got 8 x 20mm bolts from the wreckers and machined them down to 19.5mm diameter.

I have a small old electric kiln that I got at an auction some few years ago for $50 - not working. Replaced the contactor and it buzzes along. I annealed the machined bolts at around 1000 degrees to get the "Black Iron". The white spots on the threaded parts of the bolts is from the galvanising. I have drilled and tapped the end of the bolt 6mm metric so as to securely fix to aluminium backplate

I think I have been looking at the action of the FEG all wrong. I have been beguiled by all the wrong concepts developed by failed commentators. So before I commit to explaining my concept I am re-redesigning the switching. This will be from the commutator. It one thinks about it there are not so many opportunities to use when regulated by the commutator and a tank circuit. I am also mindful of Eric Dollards demonstration of lonitudinal waves on one of the early videos from Borderlands.

Cheers

Dwane

Dear Dwane,

I don't follow what you are trying to do with the kiln. If you are trying to create black sand, it won't work.

Are these bolts normal mild steel ones? If so, they are not as recommended by JB. If you ring up a supplier of goods for gas welding, maybe suppliers of bottled gas, they should be able to put you on to welding rods. The suggested types are R45 or R60. They are not steel but iron and handle magnetism quite differently. Then cut them to length and bundle them up to get your diameter. (I think it is recommended that they are varnished or painted in gloss paint to provide electrical insulation and thereby reduce eddy currents with their associated losses and heat problems.

You may be able to find iron by another method but it is difficult. (Sometimes iron is used by architects for foundations because it is rust resistant). Much wrought iron is nothing of the sort; it is wrought steel and sold as wrought iron.

Black iron

Hi wrtner,
A replacement for the low oxygen welding rods recommended by John Bedini is soft iron wire. This goes under many names, tie wire, baling wire black wire and so it goes. It is soft in as much as it is malleable and easily bent and twisted. It has become somewhat a specialised product. Most tie wires now available are mild steel zinc or galvanised coated. The advantage of using these would be their diameter options. Smaller diameter closer lamination effect for a circular coil core.

Commercially I have found that the lowest carbon steel available is 1004 and is coloured black end. I think I am correct in stating that most mild steel are around 1015 which is carbon between 2% and 3%. The Carbon affects the remanance.

To make black iron from mild steel it is necessary to anneal the mild steel in a furnace of some sort. I am lucky enough to have a kiln. The process is simple. The mild steel is heated through to cherry red at approximately 1000 centigrade, and then allowed to cool slowly. When removed from the kiln it will be coated with a layer of Black residue. This is very brittle and falls away easily. Beneath this carbon residue the mild steel now is coloured Black.

This process has effectively leached the majority of carbon from the mild steel and is classified as soft Iron. It's magnetic properties are now more suitable for high speed switching.

I also chose to go this route for my prototype as by drilling and tapping the end of the bolt, I am able to securely fix the coils to a backing plate. Using bundled wire make secure fixing more difficult.

Hope this helps.

I am putting my FEG back together to day. I have a bit of circuitry to design for the controller switching. Here I think that I have to discover the charge and discharge parameters for the pulsing back to the battery. From my perspective there are two discharge rates. 1) A battery boost and 2) Lenz boost to the coils. This is where all the headaches arrive!

cheers

Dwane

It might be worth checking with
Activity Stream - Energy Science Forum
about the latest thinking re cores. JB posts there and he might have something to add if you can get in to the right position in that confusing web site. (Never will I complain again about his YahooGroup, however bad its software may be).
