Bedini SG notes

[TinselKoala]

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 !

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.    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:

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)

The Bedini circuit can turn the glass black

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.

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.
