I surely didn't mean to be or sound down on you. I'm new here and still read more than try. I order things only to read days later that something better was found. New order...lol If one were to order, some sites use the letter code, others use the AL number, but there seems to be diff value factors of it. I'm sure I saw one site that had Al's in the low 1000's? That would make the 125 on Micro Metals totally unworthy. I wish there was some standard. I'm sure there must be that I just haven't found that calculates all these diff values presented.

On the black sand. Interesting.....but its my understanding that ferrite is Iron Oxide particles coated with ceramic then formed. The ceramic prevents physical touching as would be seen in a molded powdered iron. Black sand is not magnetic AFAIK, so I don't know if it would be better or act as an air core.
Air cores are shown to work. Be an interesting thing to try. I mold cast many things for my micro rc planes & helis. Play Dough woks well....lol
Press a know size in 2 layers, then us an xacto knike to resplit the form, making a couple of alignment marks. If sticking is a problem....Pam spray works very well as a cheap release agent.
Pls post the results if you give it a shot.

Hello All.
These last few posts have gotten me to wondering if maybe since the 5 for a dollar toroids at electronic goldmine are said to work well maybe they could be crushed and made into a larger coil or mixed with the black sand and made into a larger coil.???Just a thought.Happy Holidays Everyone.Tec

The black sand I am refering to is actually a by product from gold and mineral mining. It is very magnetic...

Well, ya learn something new everyday. I did some reading on the black sand. It definitely is magnetic. From the pics I saw I'd think you would want it finer so there is less voids in the material. It would be the same as Tec's idea of crushing the Goldmine toroids. As a binder I'd go with something very thin like a high quality super glue added to it in the form, packed in layers. At least that's how I imagine it. You'd just need to see how far the binder permeates the powder. Both sound like interesting projects. 1 hr epoxy may work well if you put enough in till its virtually dry. Then press it in the core form. Rods are useable too.

The cores from the Goldmine would be ferrite(ceramic coated particles). The sand is described as magnetite. I wonder if it holds magnetism? It may react like a powdered iron core or it may be 10x better. Placing a strong magnet on running JT's can make them brighter if oriented correctly. Here is a vid on separating it from general sand.

Edit: I got to thinking if you could buy magnetite powder. Sure enough. Didn't see a cost, but since its used in printer toners it may be fairly cheap. If that worked, it could be a source of low cost home made really good cores. Here is one of many companies I found on a simple Google search.

Funsaver mod.

The AA foldable solar chager brought the four dead batteries back to full charge with merely a few hours of direct sunlight! That comes out to 18 hours of 20 watt cool white flourescent light with the twin funsaver mod toroid.

The Power film array is so efficent, it begins to charge from the 20 watt toroid bulb when wraped around it in a dark room. Top of the line marine quality. A real power house for the fold up size of a handkerchief. Kinda costly. What a sweet combination this makes.

A very good source of Black sand is E-bay of all places... It's not bad too for a pound it costs like 8 bucks of high quality stuff.. Check it out some time.

Twin JT Spiral Knot.

I discoverd today that my twin bifilar, each wired for hi voltage, so as to create two Joule Thives twisted together, works as an a.c. inverter and a more then voltage doubling transformer. Just by charging one coil, the oscillating magnetic tank circuit outputs a full a.c. sine wave from the other, and more then doubles the voltage. This coil should be able to illuminate a 120 volt a.c. incandescent bulb from one JT with a cube of 6 nine volt batteries wired in series to it's other co-twisted output twin.

Five 12 volt batteries in series connected to one JT should power our household appliances from it's entwined mate. Probably connect directly to solar panels
to power our T.V.'s directly from sunshine!

I'm renameing this amplifier coil the "Dual Joule"! Say hello to the bi-bifilar. Spool's should work fine. 4 wires 8 ends. A.C inverter and voltage doubling dynamo. A power gain the inverse proportion of rectifier loss shows up in the same percentage of voltage increase. That's the amount over 2. There has to be amperage behind it. This comes from the marriage of the two halves in a harmonic cord. The elastic nature of time accounts for influx of scaler radiation.

@ syncro,
Congrats. A good outcome is always nice. I appreciate the failures posted too. Some feel it demeaning, but just as much can be learved and sometines a mistakes or fix can be seen by another set of eyes.
Your setup sounds sweet. Full charge in 3hrs! That solar charger must be kicking out some amps. Most are less the 100ma which would take 28hrs for a 2800ma AA. I went to the link and it shows 1.5W for a AA charger. Thats 1A!
2.5 to 3hrs of full sun would be 2500-3000ma. Bet it is costly. I never did see a description of the exact one you got or a schematic of your setup. Others have made dual JT's with Fuji's. One has the outputs in series. Maybe you could do a schematic for us worth the part # & cost of the specific charger?

@ Jbignes5,
Nothing surprizes me on ebay. I would think the finer grade particle size the better so if it was already powdered it would be easier to use. I wouldn't think it would grind or crush easily. I do believe it would have interesting results. Rods works well if you have read others posts. A straw would make a fine form to be packed and cut away later. Superglue wont even stick to it. I tried with my modeling projects.

Ok, I now have 2 of the 2 3/8" cores wrapped for testing. In case one had hairline fractures of a fault for some reason. Originally it had 650 30ga wraps for a secondary with a 26ga 3 & 5 turn primary. Output was 230vdc with a bridge rectifier. It barely ran 1 LED off the secondary! So, I did the test with a 22ga primary side. No diff voltage or current output noticed. Next I twisted 4 strands of 26ga to use as a primary with the same 3 & 5 wraps. Still 230vdc across the full wave bridge, as expected, but I can now feel a zing when I touch it. So, that did raise the output current. A good note to keep if you ever need a higher current from the secondary easily. The voltage held at 230vdc for the most part, but I did see 260vdc once when adjusting. Same results as before when tuning. If I increase the turns on the primary side in any way or combination the output drops off. Ratio wise, This is what I'd expect. I'm still baffled on why the primary is so bright @ the E-C junction, will run so many LEDs, but very little seems to be crossing over to the secondary. Even the expected voltage is way low. Even with a low current, I'd be expecting 400+vdc at the bridge rectifier at a minimum and I just cannot get it there with these cores. I did drop one and it shattered into abt 6 pcs. Oh well..............no crying over this. It will still be useable for testing and maybe as arc'd rods. I'm used grey primer paint as the red was only enough for 1. I may strip the paint do a Saran wrap to prevent shorting on a large piece for testing. It will wrap fast now.
I'd have to say to hold of buying these from Valley Surplus on ebay till I can try something else. If you are only concerned with using the primary side, they do well and the E-C will run 14 LED's easily with just a few wraps. Strange huh? I need to try it with a 2N3055, heat sinked, and a 12v battery too.
I am now going to start wrapping the 3" tan one which I believe to be powdered iron from MicroMetals. I read they are low permeability(powdered iron ones) and require more wraps, but I can follow Lidmotors schematic and compare the results. I'll post them too.

Carry on all and keep those results coming! Good & not so good! All info has merit.

@ all,
Has anyone tried secondary windings with wire gauges other than 30ga? Seems that is a standard size used. Fuji's work well with 45ga 1750 turn secondaries is why I ask.
I've considered 36ga as it's .005 dia and would allow 2x the wraps in the same space as 30ga. 1" would allow 200 wraps vs 100 wraps per 1" of 30ga.

I need a new source for 30ga wire. Buying from RS is ok to get started but you end up with 2 spools you'll probably never use all of. lol
I found one place that has 1/4lb of 30ga for $8.??. I don't know the shipping, but it has over 800ft. That alone is way cheaper.

Any good sources?

Thanks in advance.

Solar panel

@Vaporizer,

Click on "Foldables". The AA foldable film solar charger is 1.5 Watts, at 3.6 volts. The amperage figures out to around .4166. That's over four times the
100ma. This unit unfolds like a plastic credit card manager, and costs about $70.

My cool white toroid bulb has four electrodes. I think the circuits link when the gas illuminates. A CFL with only 2 electrodes would need the mods in series, and I may try that. My 20 Watt bulb is fully lit, and enough to make a world of difference in a blackout.

Hello Vaporizer and All.
Allied Electronics has some very small size's due to the price per roll I think there maybe enough on one to reach to another state AllElectronics has magnet wire in 1/2lb and 1/4 lb rolls.and I am sure Ebay has more. Hope this helps Tec

@ syncro,
I didn't look at all the details. 416ma is a respectable output @ 3.6v. The garden type solar cells will put out abt 5-10ma from the lights I have now in a dark room. Not much, but it is "return" to be used from the back side. Little bits add up in our world.
$70 sounds like a lot, but when you live where I do and average blackouts can be 4-6hrs through the year and one last year from an ice storm had some out for 8 days! $70 is a cheap price for light and safer than oil lamps when you have 2 cats and a dog.
I have the Bedini charging all my batteries from a 12v. If it gets low after a month , 15 min on the car with jumper cables and we're good to go again. I should have 8 emergency lights when I'm done. Also have a 12v solar panel. 6 of the lights will be low power for sitting around the house and 2 will be full brightness 60-75watts. That's my goal for now, then I'll be adding 555's for extended run times.
If they work well enough, I'm usually up hrs later than anyone else in the house and I could use one each evening. Eventually it will save a lot of money over time. Rooms that usually have a low watt light on in the evening could be replaced with these too. We've used rechargeables for yrs now so a supply of batteries isn't a worry. The Bedini even keeps all the alkalines charged that wander through now.
Once I get these done then its on to better efficiency.

I'm off to watch that video. So much going on its a shame the world doesn't take more interest.

Merry Christmas All!

I've cannibalized a few microwave ovens I found in the trash bin. The MOT has some good uses but is too big for this stuff. I remove the bobbin from the fan motor and it's usually a nylon coil form with a square hole. It has the end of the winding soldered to one terminal. I cut the wire and I can unwind it just like a spool of wire from the electronics store. It's usually 28 or 30 AWG, but since motor makers get their wire in bulk, it's not unusual for them to use the odd sizes like 29 AWG or 27 AWG.

As I was posting this I thought of an idea. Remove the rotor and stuff from the motor and leave just the bobbin and steel laminations. The heavy copper around the shaded poles has to be removed or it could create a short - which is what it was designed to do. What you have left is somewhat like a toroid. But the steel laminations are made for 50 or 60 Hz, not much higher. If you wound a dozen or so turns of heavier wire around the bobbin, it would be much like the primary coil on a toroid.

Anyway, you might find microwave ovens in a thrift store, or even outside at the dropoff bins for the Goodwill stores. Neighbors might have an old unused on in the garage. Or cruise the neighborhood trash bins, you might find even some other source, such as a table fan which has a similar motor.
