The germanium transistor should allow you to get the LEDs to light at a lower battery voltage. To make an accurate comparison between the germanium and silicon transistors you should commpare the input power not just the currents. Input power = battery voltage times battery current. Example: (0.88 volts) x (1 ma) = 0.88 milliwatts input power. With the germanium transistor it may take more battery current to get the same LED brightness, but when you compare the input power, the germanium will probably be the same. The advantage of the germanium is that it will work with lower voltages so simple home made batteries should make it work (for example, a nail and a copper wire in salt water)..

@all
This topic is moving fast and there is happiness on all of us.

@gadgetmall and @innovation
You are going very fast on the discoveries. I need some time to digest all the information available now.

@pirate

The fuji circuit arrived today. It is as the circuit I used to make my first neon bulb to light. I broke that one doing experiments. The only things left are the transformer and the transistor.
I will use this one more carefully when experimenting.

Thank you Bill !

The photos I took did not get too clear and I tried about four times.

Great work! We will need all the juice , some from the hemf , some from the secondaries , and we could send the initial pulse to one other battery and better would be switching battery on each cycle it would run longer , and we may get a better idea on running it on caps.


@allso

The aluminium wire need a special connector to be directly connected to copper , yes interesting, also it is more resistive so you get a higher voltage per turn then copper, also it is 2 times more conductive that copper per weight,(it means you get a big copper wire conductivity in a smaller size and a higher voltage, This is a god idea for secondary!

Also, I need a little clarification on something. When I have a cap across the + and - of my LED(just for example), what matters more, the uF or the voltage? like above, I have 200v 560uF or 6.3v 6800uF. What would make my LED brighter, in theory? Caps still confuse me to no end. Does the voltage rating just say that it will output the current at that specific voltage and the uF just say how much current the cap can hold at that voltage? Can it hold current at a lower voltage and output it at that lower voltage? Or does it always output at that rated voltage? Can they hold more current at a lower voltage than it is rated for?

I suggest you start here:

Right thats why i always state the battery voltage . The main thing is that i have accomplished something open source that has not been done yet .With the exception Of Jeannas Experiments her lowest Ma per led is .78ma i believe . that is good too .  This opens the door up to now power many Leds and motors or whatever from earth batteries and possibles Thermoelectric Cooler module . i have one that puts out 12 volts when heated on one side or small solar cells and even shining light on red leds to produce power . i understand they produce 1.5 volts in sun . i think that one or two will be enuff to power this circuit . and i expect this germanium transistor to oscillate at less than .20 ma . I have made it possible to do many things for practicaly no current .. My next few steps are going to be for the 0 volt fets which then will be self powering . it might be possible now to run a second secondary and loop it back because of the Low Volts /current it takes to run it . I might try that with a Super cap .Also i might add that the toroid is now extreamly sensitive to touch . If i touch the  toroid the lights go out and the current goes up .  Also with a magnet
