Crystal Power CeLL by John Hutchison

I put the scope across the JT and found the the 10hz pulses were in fact bursts of 33Khz.

So, the thing oscillates at 33khz, but it only reaches a high enough voltage+current to turn the led on at a rate of 10hz?

The JT was doing the right thing. Also silly nuts here didn't use a current dropping resister between the cell and the base of the transister.

hmm
I think this resistor is the knob of the switch so to speak.
In my experience,if you raise the resistance on the base of the transistor the frequency goes up, .. but the voltage goes down.
So, you have low voltage, and the frequency is already very high. I think you must be using a very small toroid. Is it one from a compact fluorescent?

You have something to play with here.

Please give me some information on this joule thief?
I would especially like to know how many turns on the bifilar, and if you just made it or if you went through the tuning process.
----

I remember a member on the earth battery found that he could only start his jt from the eb when there was no base resistor.
hmm.

This meant that the battery voltage was always going to be clamped at around 0.45V. I use a BC 547.  Well anyway it's still flashing.

Here is my thought right now.
You may have made a battery with a bunch of capacitance along with battery chemistry.
If you were to add a capacitor in parallel with a normal battery, you would see this flashing as the cap fills and discharges even though the silicon should not be turning on at that level.
So, the battery chemistry part recovers and fills the capacitor part until it can light with a burst.
It cycles 33k times but only accumulates enough to show the light 10 times.

I have been seeing something like this with a lightbulb that has capacitors built in. It drains the battery to well below the threshold of the transistor (yet in this case cannot light or even flash because there are 20 series leds). I think we might be seeing a similar principle at work.


This is cool, Ian.
I have been trying to understand my lightbulb problem for a while, because I think it might be a clue.

Oh... I went on youtube and i read a comment on one of  john hutchinsons U tube vids and apparently he has used niobium in some of his mixes.....
Is niobium a good dielectric metal?
Is it possible to mix with rochelle salts,quartz,tourmaline and other mineral powder compounds
Im gonna have to try a load of different sample cells with materials you have used and some of my own materials like..
lutetium,magnesium silicate,kaolin,selenium boron,palledium powder and powdered bismuth and many others.just got a camping stove from a boot sale and my vandegraaff kinda works around 200 volts of somet liek that. i have not been able to take any photos at the moment but when i do will post the ...my room is too dark and the lense light sensor in my cam is malfunctioning
Ps are epson salts different to rochelle salts and if so...how?

G'day all,
@das:
I don't know much about Niobium but if you can get some and use it in a cell then I would be very interested in your results.
Epsom salts ( magnesium sulphate) is similar to rochelle salt insofar that it has piezo-electric properties. I have used it in a few of my earlier cells. Many of the chemicals and elements you mention I would label as dopants.

In my view there seems to be two distinct types of "crystal battery".

One is of the mechanical type, that is the use of the casimir effect. Hence the need for rochelle salt. JH bases his cells around this principle. The high frequency oscillations created by the rapid squeezing of the rochelle salt between micro metal or silica plates is rectified by an electrode which acts as a semiconductor (diode).

The other is based more on the solid state semiconductor matrix. ( Marcus Reid). Where a crystalline matrix is doped with semi-conductor materials and polarized during crystal formation. In effect making the whole cell an energetic diode. It is possible to use the cells early stage galvanic reaction to self polarize the cell, although the odd kV wouldn't hurt. It is best to allow this type of cell to cool down slowly over a few days so as to produce a good crystal structure. A JH cell can be ready in half an hour.

@Bill and jeanna: To make sure I had enough current to run the JT I put 5 cells in parallel. Same thing happened, it flashed. Well at least for a time.I also added a 470 uf cap across the battery bank. I left the setup overnight and in the morning I found the flashing had stopped and now the led is on all the time.( not very bright ) The other developement is that the frequency of the JT has increased to 215 Khz. The JT may be conditioning the batteries in some way, afterall, they are resonant devices.

I gave the JT potted cell another bake today and it should be ready in a couple of days for testing.

I would like to thank you guys for all the helpful hints and comments, this is great.
cya later

I know it's been mentioned a couple of times on ou here but since some of you are researching and testing as well I would recommend reading the entirety of T.T. Brown's study of Petrovoltaics here:
http://www.qualight.com/petro/index.htm
and his research notes:
http://www.qualight.com/journals/index.htm
Especially #4
I am also going to do testing myself.

Oh this is very cool.
Great work, Ian.
And as always, thank you for sharing this.

I have been successfully conditioning and charging a previously bad Nicd with the secondary jt pulses.
If static charge works in a battery maybe it is also able to work in your crystals.
beautiful...
