NICE my 100 20,000mcd leds have just come in

@Pirate

Can you let me know where you got your magnesium and carbon from?

I got my carbon rod at a local welding supply company called Airgas. (They are on the internet)  I actually ordered from the website and had it shipped to the local store.  The part number for this is buried somewhere on my Stubblefield Coils and Speculations topic.  It was 1" dia. x 18" long and about $20.00.  Someplace in my files from 2 years ago, I have the receipt with the part number if you can't find it.  These are called gouging rods in the welding industry. (No copper cladding here)  The magnesium came from another local company (Miller's Bottled Gas) that supplies propane and propane accessories.  These blocks are used when they set a tank in the ground to stop the corrosion of the steel. (sacrificial anodes)  This 5 pound block cost about $45.00. and comes ready to put in the ground.  They had to order this from a warehouse someplace.  If you need a part number on this too, let me know.  I would think any similar business in your area would have access to these same blocks.

I hope this helps.

@ Jim:

Nice coil man.  It would take me a week to wind that many turns, ha ha.

@ Pirate

Thank you for the infos sir!

In your set up it looked like you were using 2 carbon rod, is this true?  Actually what is in your set up exactly?  The videos I have seen are all at night!  To me it looks like it has great potential.  I have been thinking about setting up a nice looking track light system for my living room.  I'm not sure if an EB could power it but I could always make a 1.5volt power supply and start saving $$ now!

Yes, I am using 2 carbon rods in my set-up.  It is actually the 18" long rod cut in half because in the winter when I first did this a while back, I could not get the rod deep enough into the ground, so I cut it.  I have the 2 carbon rods buried on the north meridian alignment (Not magnetic north) and 12 feet to the south I have the mag block.  The 2 carbon rods are wired to each other.  I am sure I can light a bunch of regular power leds which I will try shortly.  I have been using the high output leds in my tests thus far.

  so, are you saying that maybe I should stick one of the supercaps after the JT and before it goes out to when I try to run the Fuji circuit?

No, that isn't what I was saying.
-----
parenthetical remarks:
Because, my experiment with the 2 tier showed that although the PULSE from the first tier IS passed along to the second tier, the power drops off the cliff.
In fact the crazy loop that works well in the 2tier experiments are using both toroids and both secondaries and one bifilar from the second level., like Gary's and also like Jim's multi level circuits.

(On my 2 tier ckt, the only coil that is not hooked to all the others is the bifilar on the first tier that is connected in the BJT way with the transistor etc.
------

But this is not what I was talking about when I asked about the supercap.

so, now I can try the Fuji off the EB with a supercap after the JT and before the Fuji.  This is a great idea to try! (If I have this correct) 

Don't let me stop you just because it wasn't what I meant!

I meant to directly connect the fuji to the EB, but if the Kentucky powergrid  isn't strong enough, add a cap somehow between the EB and the fuji.

I assume you are connecting the magnesium side to the neg side, and the carbon side to the pos battery tab in the fuji ckt. So, put the cap across the battery clips of the fuji ckt.

Another way to say it is,,where you had the led in your first EB that lit, put the fuji ckt. Now, put a cap across the fuji battery just the same as the led.

I guess this is hard to describe.
