Hi all,

Bruce

If you shorted  your first layer, you will have a force against electromotive CEMF. At the point of reference TDC, you can do it through a resistance of 100 ohm, with a reed switch.

Hello everyone,

GB,

In Orbo, a Battery of 1.2V 10A/H and not 10A. I make function my Orbo engine with 0.1V and puls 80mA. It is not the capacity of the Battery in A/H (Amp per hour) which counts, but autonomy.

@Bruce:

At 1,000,000 permeability for the metglas core, it will take a lot of volts and amps to saturate it.  That baby can hold a lot of flux before it even starts to saturate and lose attractiveness.

Steorn is able to do it with 12 volts while drawing around 1 amp (according to one of the demo talks).  This is 12 watts.

The Orbo on display has a 1.2 volt battery with 10 amps which is also 12 watts.  You're at 10 watts.  I would try to increase your watts to around 12 and see what happens.

What has me puzzled is you have the metglas core almost completely wrapped and the coils in the Orbo is just barely wrapped.  This may suggest the metglas isn't the core Steorn is using.  We need to eliminate the other possible reasons you mentioned before drawing any definite conclusion though.

PL, I don't want to hear how the amps are more important in saturating the core than the voltage.  I can already hear you.

The Metglas cores are far far far easier to saturate.

Saturating a core requires voltage & time for a core with a given saturation, and of course given that the turns are the same. A core that saturates at 0.5T requires half the voltage (and same time) as a core that saturates at 1T. What is great about the Metglas and other ultra high permeability cores is that it requires hardly no *current*.

So if we compare two identical cores in size and # of turns, given the same voltage & pulse width, the core with 100 times the permeability requires 1/100th the current to saturate, and hence 1/100th the amount of energy to saturate it. That is basic physics, which I have confirmed in my experiments time after time, and is seen in FEMM.

Is there a better core than Metglas MAGAMP. I have no idea, but future technology will indeed create a better core. I know that the Metglas MAGAMP works well for an orbo replication.

I think Steorn used a Booster coil approach also.  I'm attaching a photo courtesy of PL that he posted way back in this thread of a coil in the Orbo Demo.

The first photo is an enhanced image that was sharpened, color adjustments, and flipped horizontal in order to see the different layers better.  The second photo is the original PL posted.  It is very clear in the enhanced image there are at least 2 layers while each layer has a different wire thickness (Pay careful attention to how some of the turns in the wire are raised much higher than the turns next to them).  Compare the enhanced image to Naudin's Booster Coil and you will see the similarities, http://jnaudin.free.fr/steorn/images/boostedcoil.jpg

I'm using 3 layers on my Metglas MAGAMP core. This 1805 core is 0.82" OD.

BTW, I have a big announcement to legit researchers in a few, as soon as I read all of the new posts here and at the steorn website.

To legit researchers:

Again, I do NOT recommend shorting the core. I understand people for the most part are followers of mass majority, and you'll want to do what most people here are suggesting. I'm out numbered here, LOL. So when you do it, short the core, and when you learn that it's not working well, that you just can't get the darn thing to self-run, then please do not give up on your orbo replication. Please continue on. You will get success if yo do so. There's a lot of noise here that might distract you. Also Metglas MAGAMP cores are working great for me in the orbo replication. There might be better cores, but at least I can say my "tiny orbo replication 1" using the Metglas MAGAMP core was tested at 170% efficiency (less losses in electrical resistance from wires and the mosfet), and also I have some big news today. No, nothing like a self-runner ... at least not yet  . One step at a time.     Give me a few weeks of tweaking the new "tiny orbo replication 2"  and then I'll start working on what it will take to get a self-runner.
