Bedini SG notes
« on: January 02, 2014, 05:43:34 PM »
I'm interested in building a Bedini SG. Is there a page on Bedini's notes because there seems to be so many little things that can make a difference. I think there's a new book on the Bedini SG and a dvd series but I don't have spare money. Maybe Bedini wouldn't mind if some people wrote notes here? Here's what I know. Please correct any errors if Bedini didn't say it.

The Bedini SG is about low power.

I heard that the north side of the magnets should face outward.

The weaker ceramic magnets work best. I heard Bedini say he doesn't use neodymium magnets for the SG.

Don't swap the rechargeable (radiant) battery with the source battery. See the following paragraph.

The charging battery becomes the radiant battery and requires at least 5 complete recharges to become conditioned, a good reservoir for the radiant energy.

The environment around the Bedini SG requires time to build up or whatever the proper wording is. Perhaps related to the charging battery conditioning.

Bedini seems to always use npn transistors? Not mosfets. Is there a reason for this?

If you use a capacitor to collect the radiant energy then i believe it should be a large polarized cap, but i feel reachable batteries are much better to collect and hold the radiant energy. I recall Bedini saying that the larger recharging batteries are better.

I've heard somewhere the coil spike should be as fast as possible.

Use good ball bearings haha. :)

Absolutely.

The site has become a navigation nightmare and I could not find that series of threads.

Well done.

I know this maybe outdated be I want to answer this question, as it could help someone :

Channeler say : Bedini seems to always use npn transistors? Not mosfets. Is there a reason for this?

I've recently made one (which is not very efficient), with a modified floppy BLDC motor & or a fan motor.
I've tested the Mosfet N-Channel, drived by the trigger coil, but as expected this don't work.
The trigger coil cannot get enough voltage when collapsing to drive the MOS transistor.
With an NPN "bipolar" transistor, this work because they are sensitive to little current. (I use a small common 2N5551)
Sometimes, NPN are so sensitive than it's possible to randomly drive them when the base is floating or if touched with your finger.

Also I've tested an npn which drive a Mosfet, this work but with just so much wast of energy.
Maybe this depend on parameters, but I think Mosfet aren't very efficient with low profiles bedini.

The problem is choosing the right MOSFET.  BJTs will turn on at a low voltage, and if the collector current is small a low total charge.  If you pick a standard threshold voltage MOSFET, then you need to get to about 4V.  In addition, depending on the MOSFET you could need to move multiple to many nanoCoulombs of gate charge to turn the device on and off.

Ditch the silly Bedini driver circuit and use one that is much more flexible, yet still yields the same output effects.

MHOP trumps Bedini. You don't even need a rotor at all.

Ho thanks didn't know all that, really informative for me.
I've tested with a N-MOS K3570, the datasheet tell me (if I'm not wrong) the min cut-off voltage VGS equal 1.5V.
My bedini trigger coil is so little (one of the 3 coils), than I doubt getting more than 1 volt.

MHOP trumps Bedini ? I will check the video !

Basically you just need to be able to trigger your coil-driving transistor with the smaller voltage that you are getting from your sense coil. The MHOP op-amp first stage allows you to set this trigger voltage to be a very small value; the system is very sensitive. Then you use the op-amp output to trigger your driving transistor, which can now be a power mosfet of any kind able to handle the voltages that your coils will produce. I'm using an IRFP450 in there at the moment.  It's actually a very simple circuit, and the TL082 FET-input dual opamp costs well under one dollar per chip. The output side of the circuit, diverting or using the main coil's inductive collapse spike,  can be any Bedini-type charger/desulphator scheme you like.

I've taken a look at the 2sk3570 data sheet. Yes, the min cutoff gate voltage is 1.5 V... that doesn't mean you'll be able to get it to turn on cleanly at that low drive voltage! Really you need 4.5 volts and a good inrush of current to switch it cleanly, and clean switching is important for producing the inductive spike effects from the Bedini-coils.  Plus, the transistor has a really low voltage rating of Vdss = 20 V ! It's designed for low voltage, high current applications and I doubt if it would survive a Bedini SG motor. The neon in the standard Bedini motor lights up at 90 volts! You can easily get 5 or 6 hundred volts in the spike.  That being said.... if they are cheap, try it and see! But really, you should use something more robust, I think.

Yep, I will try, I've few LM358N (low consumption).
I will show the trigger circuit for interested people. (maybe a little LTSpice simulation)

You're right I've tested this K3570 (desoldered it from scratch old motherboard, alim part) and it cannot get drived without less than 5V. I've try with an NPN drive, and it cannot start the motor "NEON don't fire, Led do".
So maybe I haven't killed it because inside diodes protections.
I should search if I have other, or buy it. My neon light are exactly thoses : http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=120842243968&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

PS : how more than 500 video TinselKoala ! , Thanks this it instructive, I will let the time spend watching all of this !

Those are pretty neat little neons. They fire at a slightly lower voltage than the NE-2 that is common here in the USA; this is probably a good thing!

The Bedini circuit can turn the glass black, as you can see in my videos above. This happens when the neon gets more voltage and current than it is rated for. Sometimes the Bedini circuit can actually make bright purple flashes in the neon!

I have a lot of videos, it's true. I paid a lot for this silly camera and so I figure I should use it as much as possible.   ;D At the moment I've got the cost down to about a dollar per video..... LOL.

I've made a playlist of all the MHOP driver development videos so you don't have to search through a lot of irrelevant stuff:

http://www.youtube.com/playlist?list=PLml9VdOeqKa8F1PebS_EX7AX2aA_ZZtb9

The project was inspired by Mile High and we developed the circuit with a lot of back-and-forth here in the forum, and I learned a lot from the collaboration and from the other folks who occasionally chipped in with advice and comments. The full final schematics are in that last video in the series.

Many thanks, I will let you know the evolutions : I should probably start a new thread showing what I've done ?
(which is for the moment littles experiments based on what others have done)

This is interesting, some "brand new" that I buy was already black ? (And I suspecting was used before me)

I'll bring this conversation from the Cap-tret thread to here.

Anyone want to analyse the Bedini patents claims and text. Here is a link to three of them.
https://sites.google.com/site/johnbediniresearcharchive/john-bedini-u-s-patent

First one the Monopole Motor as the patent calls it, US 6545444.

A couple of odd sections of an "odd" patent. He uses Back emf to describe both the coil discharge and
the drag effect, then he says the circuit changes the Back emf to Forward emf. However the coil
discharge is Forward emf the entire time.

Before that he says that "if the energy in phase (the power out phase) is increased by additional available energy in the electromagnetics themselves".
The important word is "if" because if it doesn't then it won't do what he claims, and "if" doesn't mean "does".

A very slyly worded document in my opinion. It makes claims but only "if".

I am still yet to fully read the document, but immediately it reads quite odd.

..

All pulse motors that charge a battery with the diode output do the same thing, while the coil is discharging the current is in
the same direction as the charging current they are both "forward emf". Does the discharge current from the coil produce a magnetic force to drive the rotor ? Maybe. Does that make OU or extra energy ? No.

..
All kinds of weird talk in that patent. Anyone else read the part further on in the summary where he say's, "the Back emf created energy".
Seriously, he talking of creating energy, in a patent, I find that very curious.

..

I think maybe in his descriptions of the operation of the motor he begins by disregarding the first cycle and describing the result of
successive cycles which disregards the initial input and so "apparently there is theoretically almost double the energy for each
successive cycle" both phases, each cycle has two phases. A trick of the tongue.  ;)

..
