@totoalas Cool video. I have been looking at those lamps for a while. Did you know that they make those, also, in a donut bulb that is half red spectrum, and the other half blue, for greenhousing? I thought that was neat.

Hi Kyle
Im thinking of your alum wire in a magnet core think will explore the Slayer ckt to try this have lots of microwave ring magnets 2000 pcs in my collection the new T5 fluoro will surely fit

The bulbs contain mercury pellets. Not something we need to be adding to the environment but I would like to play with the ballast and the inductor.

Hi zardox
I think I will stick it out with the old fluoro lamps where we had lit them wirelessly from the previous post s

the magnet wire configuration with aluminum coil maybe will need some tweaking T5 fl lamps with 100 mm dia can be a good test lamp

@ kcarring

I have that on my list of things to do. This is the simplified version I was thinking of trying. Layout is for a plugin breadboard. You might want to try it. Resistor value is not critical. Use power supply with limited output current or Mosfets may burn up (I was going to use battery for power source). N-channel power mosfets.

@xee2

I have been messing around with the Royer lately to some degree of success. Looking at your diagram you denote 100 uF in the main AC cap. Can you explain the relevance of the sizing of this component in the circuit, I don't really understand what implications it has, i.e. frequency, output power etc.

Thanks

I think value is not critical. Just needs to be large enough to hold enough charge to turn on/off the other mosfet. I believe the charge in the capacitor does the switching. But I have not done any testing on this circuit. I think the zeners are not needed if the voltage is 12 volts or less. Doom2pro webpage has details of operation.

Interesting idea. I am still at the stage of trying to replicate "as good as" results as seen by Gbluer and Jiffycoil, which has leaned me towards trying to get things as close to identical to their setups; as opposed to a new tangent.. at this time. Recently I have been able to get things operating at the 1.0V level, which is some progress. So, all in good time I guess.

I find it rather interesting how in most circuits, interesting results are usually found in very low voltages. (for input). Anyone can speculate whether or not there is free energy in it; personally I do not think there is, but there does seem to be usefulness. For example, the free energy devices we do know, that work, FOR SURE: i.e. solar cells and thermocouples.. they all come in the flavor of low voltage high current output. And that is a natural marriage to what is seemingly useful for these circuits. Take a look at one 6" cell:

Specs

* Monocrystalline solar cells
* 156mm x 156mm * thickness 190 +/-20 um
* Cell efficiency 18.2%
* Pmpp(W): 4.33
* Umpp(V): 0.523
* Impp(A): 8.243
* Voc(V) : 0.632
* Isc(A) : 8.803

You get one half volt and 8A.
3 or 4 in series would then provide open circuit 1.8 - 2.4V, and enough to charge a NiFe (i.e. IGNI 240).

Now obviously, if want to invert power for use in other applications, this is not practicle... I am talking about a stand alone separate system: 1 panel, 1 battery, 1 light.

The average solar panel frame can accomodate either 36 or 72 cells. In a configuration where 4 cells were used in series for 2.4V open circuit, in a 36 cell panel, that will provide in full sunlight a theoretical 72 amp output to the battery; one owuldn't be enough, several would be needed in parallel.

In fact, just four cells outputing a theroretical 8A should provide a pretty decent charge.

Naturally the system needs to all in one area, the battery right behind the panel. Or voltage losses will occur. And, it may require 5 cells in series. I'm not sure.

You would then run several circuits to provide the light you are after.

Basically it is the complete opposite of what is done in solar power. LOL
But somehow, it seems to make sense to me.

[kcarring]

i tried about 12 times to correct some typos in that last post using the edit function but it failed to work everytime:

I meant to say, that if 36 cells were used your amperage would be so high that one Edison cell would not be enough, several would be needed in parallel to accomodate the 72 amp output. So, more realistically, perhaps 4 or 5 cells in series, outputting a theoretical 8A (and more likely a 5-6A charge on an average day) would be suffice to charge on Edison style cell, and then several low voltage light circuits would feed off that.

An alternative might be a custom panel made to charge paralleled nominal 3.6V 18650's in a a bank, and thus you'd want somewhere in the department of 5V real output, at high amps.

[kcarring]

In the above I should add the ultimate durability and "abusability" of the NiFE is unparamounted. The charge voltage can vary from 1.46 to 1.55 volts per cell. Unlike other battery designs, the exact charge voltage is unimportant. A higher voltage will result in quicker charges but more water loss that will necessitate more frequent topping up with distilled water. So in theory, anyways 4 cells in series should work quite nicely.

I suspect this setup would provide free light for 40-50 years without part replacement.

@slider

Remember the Canadian 99.9% nickels I sent you? Please experiment using those nickels and compressed "patties" of steel wool, using pure Lye as your electrolyte. They may be weak, and require a couple or three to get your voltage.

If you have only about .1-.5V input, I have found this circuit works too. Once I have settled on some component values I'll put up my results. The JFET I used was a J110 and is depletion mode, the RC feedback is high value resistor / low value cap.

It is a patented circuit. Not sure where it came from originally.

@ kcarring

I looked at that circuit some more and I think that the value of the capacitor does effect frequency. The larger the capacitance the lower the frequency. I think. When circuit switches the capacitor must recharge to turn on voltage and the bigger it is the longer that should take. But I can not be really sure until I build it.

@Xee2

I decided I needed another Xee2 JT to run a light out at the boat launch at the cabin, so I took a 120VAC-10VAC transformer I found at the dump and rewired the primary to have a CT, fired it up on a 3.7V tonight, it runs good, lots of light I scoped it for fun, strange wave. It runs at anywhere from 35mA right up to .5A. Seems to give out good efficiency when compared to the 2 watts the bulb normally uses, at least 75% - 80%, that's for sure. I like it. A bit noisy though, my other one ran quiet, maybe the bigger transformer... that doesn't matter though because it will be outside and the inverter will be way up a tree where there is good solar. Going to try an infrared switch / sony remote / on this one

[jimboot]

That's another good one

With the time these things take to wind, we may see the following:
"Ok guys, finally wound the 1500 turns. Wife was fine about it, though she says I could have made our daughters wedding instead of sitting at home winding. Didn't know we had a daughter, we didn't when I started this"

Hahahahaha must check the spare bedrooms. Maybe they're not spare anymore!

Hi guys - I found this both mystifying and exciting, but perhaps there is a simple explanation.

Im using a 30W input on the Slayer exciter (32V at just under an amp - old printer power supply, MJE 13007 - the toughest transistor in my opinion) and the receiving tower SEEMS to increase in output when I add more and more load...a trick of the mind, or something more interesting? You decide!

Add more load and output increases - YouTube

I'll be adding a lot more in the next few days....as many CFLs as I can lay my hands on.
