Plazma,
That is right I just don't grab parts out of differnt things, I make a big study of parts. The most important thing is the SOA curve, I always use that chart, The bonding wire at DC. Here is a chart so you can see.

Mr. John Bedini

Thank You so very much

I was peeling my eyes over the datasheets last few years.
I just begun to feel going nuts, and would probably do so If You didn't clear it (for me).

thanks a million!



it IS a "nasty" process and there aren't many good BJTs out there, in the open market, right?

I saw that too. Mathew, you are using solid state relays, right? There should not be any problems with the contacts in that type of setup, like with mechanical relays, so I wonder why it is not in every pulse? Maybe you could play with that timing a little bit and try to get that going on more often? Maybe the scope just can't catch it all the time?

Where are you scoping Matt? The output, or across the batteries, or where? I think you said across the load, but just want to be sure.

I can't do jack, I'm on the road, so I'm using you to live through, until I can get back!

Thanks,

Leroy

Leroy,

In Matt's video he said he was switching at 2hz. To me it looks like the wave form you are seeing must be from the motor switching (brushes or bldc?). I could hear the 2 hz switching but the scope showed multiple cycles. The occasional deep spike to the negative may have been when the 4 battery switch changed sides.

@Matt, Can you tell us what kind of motor you were using for the load, its ratings and any voltage/current readings you took from it while it was running? Thanks

Patent?

Hi Peter,

Thanks for this article. In it, it is said that Baldinelli invented a burgler alarm that could be built into a door knob and also that Baldinelli held a patent on the present device.
Well I found three of his patent on the door knob alarm from the 1965-68 era, all three patents include the same topic, a signalling device built into a door knob. Here they are:
esp@cenet — results view

However, I have not found any other patent from Baldinelli nor from Anthony Galluccio on this "dual relay charger" device.

Are you or John aware of such patent? I would be interested to read it.

Thanks,
Gyula

Gyula,

Clearly, the article says that Baldinelli "holds a patent on the device". It also says that he was "attempting to sell the invention" to Ford or Raytheon. The latter is a major US Defense contractor, and since there is little else to find in the public domain on this subject, we can only guess what may have happened.

Since it is nearly impossible to raise money for an invention without patents, and since he apparently raised about $250k, it is within reason to believe that a patent DID issue at some point. If that is the case, then it is also probable that "something" happened later that made this patent impossible to locate today.

The article is loaded with anecdotal inferences, many of which become clearer the more often you read the article. For instance, Galluccio was Baldinelli's attorney, as listed on the Door Knob Alarm patents, so his statement concerning a patent on this device should be considered an "informed" statement, as he may also have been involved.

If a patent did issue on this invention, neither John nor I have seen it.

Hi Peter,

Thank you for all the information.

Paying Attention to Details . . .

Hi JB,

Thanks for posting the SOA plot - very clear - especially given the labeling and hilighting you added. Very informative. What you just demonstrated by this example brings to mind another instance of researching parts - why use Lincoln R60 1/16th inch ID welding rods for a transformer core like in the SSC and the SG coils rather than Ferrite like mix 77? I pulled the BH curves for silicon steel transformer laminations where the steel is ~0.75% Manganese and 1.5% to 2% Silicon. The BH curve is nearly flat whereas ferrite in the VLF range has a significant "bulge" (i.e. lots of delay/losses). Lincoln welding rod composition nearly ideally matches that of transformer steel laminate (but at a fraction of the price) and the rod is in the proper physical form for a tubular, "laminated" core. Nice - no accident that. The Devil's in the details - gotta pay attention . . .

Looking at this trace again, it is interesting that what appears to be a deep pulse to the negative is randomly appearing.

The dip followed by a flat line is the circuit shutting off the power. You can only see that if you run half the circuit. Thats not what I am trying to point out.
The circuit runs 225 milliseconds then stops 25 ms then switches. Everything is running through a bridge. So when you shut it off, it spikes and does one of those funny steps than Mr John drew. Mines to the positive but I am pulling the load off the ground side. So thats why I filmed it to see if this is what we are looking for in the switch. Although mine is in the load.
The rest of the wavy line that shows up is the signal from the motor.

2 HZ??? Wow...I would say I have a tad too much HP since I can switch @ 500HZ

The motor is going to run better at slower speeds of switching, but you may tip the balance you need to maintain a charge state with a bigger motor.
I actually I did a run today at 6.6 hertz and it did just as good. So I am not settled on any one rate yet.
2 12 hour runs lost .10 of a volt from 4 batteries each time.

So I still am not where I wanna be yet. Although I might be selfish, I want my batteries to charge. Some kinda way.

I am going to run a Custom motor prototype I have tonight and see. Its based on my simple motor so it should add charge to the system.

In Matt's video he said he was switching at 2hz. To me it looks like the wave form you are seeing must be from the motor switching (brushes or bldc?). I could hear the 2 hz switching but the scope showed multiple cycles. The occasional deep spike to the negative may have been when the 4 battery switch changed sides.

@Matt, Can you tell us what kind of motor you were using for the load, its ratings and any voltage/current readings you took from it while it was running? Thanks

Your right!!.
The motor is 350 watt scooter motor 24 volt. I like to run it with no load to test because it does not produce counter EMF on the TS, at least that I can see, until it has to work. It only draws 1 amp to free run.
I have 25.1 +- volts of potential on the high side at any given time. Thats through the switch's. When the motor is done I have about 16 volt hitting the batteries on the low side.
The bridge has 12.6 or so of potential without the load, with the load the bridge has about 10.27 left over.

I connect my scope lead to the negative side of the bridge and I ground on the positive.

I ran a one hour load using a cap in parrallel with the bridge to drive the switching but that lost too much power out of the system. I maybe need a smaller cap.
OR MAYBE... Some one could point me in a better direction.

A side note on those relays. I have a couple of those type in my CNC machine that operate the air chuck. I replace them on a regular basis as they will fail without any warning and with very little use

Maybe you got a different brand. I read alot about them before I bought them. They get good reviews for reliability. They are also the fastest relay I could find.
Alot of solid state mosfet driven relays are prone to problems when used on an inductive load. They need diode protection across them.
They say these do but I already ran them on a an open looped pulse motor, with no problems.

All in all I am happy this one seems to work better than any other I have had and its easy to test on.
I'm gonna setup a 24 volt system and run by 1.2kw motor and see how it does. If I can get 2 months runtime out of a charge I'll be happy for now. But I am still looking for that charging effect.

That explians it then. Thanks Matt, I knew that you were not trying to illustrate the trace in question, but it did peak my interest.

Matt,

Good job on all the work and info. I know this isn't what you want to do, I'm assuming your using a 12v motor with 12V batteries. Since I'm not sure, I can't give you any suggestions (not that it was asked for or even needed), but you need 2 volts over whatever battery voltage your using to get them to charge, so maybe a lower voltage motor would help. Or, as you've mentioned, increasing the battery voltages. Sounds like you've advanced with the slow speeds...that is very nice. Congrats on what you've accomplished and ..... time will tell. Perhaps you should just run that bad boy until you've reached 12.0 V on the batteries and see how long that puppy will run? See if you can duplicate or surpass your 84 hours or whatever it was.

Electron Bunching

Now this is getting interesting....

I was fooling around with the 3PDT mechanical relay Tesla Switch and decided to try some coils as a load.

I put on my large generator coil - 83 ohms of 0.5mm wire. 90mm x 90mm spool filled with wire.

It only draws <100mA, but boy does it give a kick when the relay is switched. None of my digital meters behave anymore, they all freak out.

The spikes on the scope are way off the scale, but here's the kicker...

Probing around with a NE-2 neon lamp, holding one leg in between my thumb and index finger and touching the other end in various positions around the circuit (relay contacts) produces bright orange flashes, whilst pulsing the relay.

Probing the battery terminals produces bright orange flashes, probing dried out electrolyte on top of the batteries produces bright orange flashes.

Removing the battery caps and probing inside the holes WITHOUT touching anything else produces smaller orange flashes.

Accidentally getting too close to the relay contacts whilst probing the inside of the battery produces a BIG electric shock from left hand to right hand and causes expletives to be yelled!

I really need to get the oscillator working

John K.

Didn't have a chance to reply this morning...had to leave to fast.

This could be the electron bunching scenario that Bearden or somebody else talked about, or maybe just an HV pulse causing the neon to glow, but I've seen "light" glows even with JBs cap pulsing circuits on the case of batteries, so you've surpassed that little "light" glow with this one. I never tried to do that when I was using the relays...it is a good test to see if any high voltage is getting to the batteries.

and

I'm impressed with you guys, I'm just sitting over here wishing I was home! I could try all these things and maybe have something interesting to say...or not.

Keep up the incredible work, slow and steady. Document everything...so I can pick your brain when I return.

[ldissing]

Wow, what a leap into the unknown for me!

Hi,
I will go on in slower pace now on, since in need better digest what JB has to say, and I will spend more time with my local "Master Foo" on BJT faring...

@ALL
consider this:

A. The solar panels react to only a narrow band in the far IR region of the solar spectrum, thus the low yield of energy. They are made of Silicium.

B. The BJT we use today are made of silicium - a opto uses an ordinary (almost) BJT and merely irrigates it with a IR led

C. open up (on a lathe) a TO-3 cased BJT and expose it to light - measure it - it produces energy from light (=far IR spectrum). You Have a nano Solar panel now

D. Use the same (lobotomized) BJT and irrigate it with Your favorite remote control: It will change resistance in accordance to the pulses it receives from the IR diode of the remote. You have Your personal opto now

E. "IR" is "heat" the more "far IR" the more "heat" - what if a "properly biased" BJT emits "heat" while "heating up" the junction (below 0.6V), just to absorb it back once in the "negative region" (just atop of 0.6V) and the more it has to absorb, the deeper it goes to "negative" region. Moreover, a correctly chosen BJT might even not stop in depleting the heat built up on the junction by its self- It might "sink" heat from the body and further from the environment?

SO, I go now examine my few "de capped" BJTs and play a bit.

I hope You all had enjoyable reading.

You are making my day, love it.

Actually I think I have too much voltage, I have 16 somthing volt over the battery. But I wanna power the switch with the circuit.
I actually have one running, I posted it a while back, transistor and relay based and runs synced to a prototype motor that has been going for about 4.5 months now. Its at a friends garage. Him and me built it so I could prove to him how these things work. It about on its last leg though.
We'll see how this one does with a little better prototype motor on it.

Now that I have got the switching working with ease I am gonna work on the the scalar charger I built. Start that next weekend or so. I got try that too.

Lero

Lero, (no why)

Yes, it's the HV pulse that causes the neon to flash. And yes, the HV is definitely getting to the batteries - when the meters are on the battery terminals they go into "freak out" mode. I had to switch them off else they might blow.
if I'm getting a belt that makes me swear, imagine what's happening to the poor meters!
A good analogy is when you touch the end of a spark plug lead - yeowch!!

Also, just thinking out aloud - every bit of energy going into the coil is being returned to the system, PLUS more. Nothing is being wasted.

Tesla Switch

Leroy,
You got that right 186,000 pounds of parts, and tubes too.
JB

Bit's,

Well, I hear you on grabbing whatever is at hand, wish my EE skills were better too, been doing software too long....I thought about that, but my thought was that he is expecting high voltage spikes and some of the low voltage optos might fry? At least this was my thinking although, I'm sure he has those H11D1s around, since he uses them for his cap discharge circuits, etc. But, I'd bet he has plenty of other types around too, he probably has more parts around than Motorola :-),

Come on, don't you guys remember, Lois lane and Jimmy Olson was being held by some crooks. Then Superman shows up and charges the dead radio batteries with a lighting bolt and saves the day. Oh I forgot some of you may not be that old, I'm dating myself. But just think if you get the switching right you will be charging batteries with high voltage, much less current for the same effect.
