@all

the scope says 200kHz and the wave form starts large then shrinks like a wave hitting the beach its crazy. It looks like the volts are hitting over 30 at times!

With so many people working on earth batteries perhaps you could post some JT results you have gotten using the germanium transistors to convert a 0.2 volt input into a 1.5 volt (or more) output for charging the super caps. I think a lot of the earth batteries do not always put out over 0.5 volts and thus will not always run a silicon transistor JT.

. Hmmm . WE all i can say is the transistor i use are Mill Sec Us army and Rare . I test each one. As you know i am helping in a funded project for ASRF in The Black Hills and Expensive Data Recorders are being used along with Scientific Evidence of the Earth Battery  Length size spacing moisture magnetic ley declination , all the variables .. We are not allowed to use Germanium Transistors for earth Battery because this has to be totally replicable, part have to be readily available   and cheap . All My jts are using 2n3904 and 2n2222a can for the Eb project . some results were posted for altrez on My weekly  test . earth battery will produce over 1 volt using the proper materials . We are using eco friendly materials as  to not harm the environment  . We don't use lead cadmium etc.. I sell the germanium transistor for the low power jt projects to individuals that wan to run their Jt on a low output eb . A germanium requires that the toroid be would different . More turns on the primary ,lots more . The Frequency is not near the 2n3904 . once a good primary is wound then the ger transistor will perform as expected of  a germanium . Low input high gain . I personally have several Germanium Jts but there data is already posted . .20 volts .20 Ma. . with tweaking i can run on one .16 volts My eb put out close to 2 volts as high as 12 ma sometimes . Normal is 1.1 volts at 3-5 ma . You have to use a proper electrolytic in parallel with any eb . Mine is 3300uf 10volt low esr

@all,

I think that lighting LEDS / Neons / CFLS form a JT is cool but what I am finding even cooler is that it makes one heck of a charging circuit. I think the LLA1 is going to be a sustaining charging device.

To drive / push my main Toroid configure 5 2.9" Toroid's all connected together.

I am now charging a small electrolytic cap with the same battery that is charging the other battery. This tells me two things 1. that I still have room to harvest energy and 2. That once I add the micro controller for switching it should be hands off

I want to thank you all for the great support!

Take care!

lookey loo..

I just got 5 toroids and 1 rod.
They range from the size of a nickel US for the eyes to I think 2.4 inches for the mouth. Hi flux and higher flux u=60 and u=125 the big one is u=125
The rod is for a stubblefield generator. I will someday make just one more with this at the core.

@MK1 these are pale green in their real color.
@Altrez. wow. good going!

Nice! Can not wait to see what you do with them
