Woah, that is interesting.
I wonder where we can get them without so much internal resistance?
That is a good amount of multiplier effect, xee2. Thanks. EDIT: Oh now I see. I missed the 6 to 60, I guess it isn't so good afterall!

here, I try again:

@ jeanna

What is the part number of the germanium transistor you are using. I will try to find a data sheet. If you have a data sheet can you post it? They have lower gain than silicon transistors and so you will need a lower base resistor value. I have not made one so I have only guesses. Maybe Gadgetmall can help you.

He did give me the datasheet. It must be here somewhere...
2N1308
I am about to solder it to something real, so I can just put it out there.
How much of a part do you think the gain plays here?
I was pretty sure it was the switching that made it all happen.
It is way too bright at 118 ohm, so I think I will keep it there. I can get 1 more volt when looking through the secondary, but, I won't be using that secondary for now.
It is a small secondary and I am getting 17volts, so it should light 4 lights well, but for this, I will use the BJTL spot, because, IT is what can use the very low voltages.
I am sure it will work.
I will let you know.

@all

Now if we go back to 1/4 wave length , i assume that most of hour house hold electronic
Are made to work on the 60 or 50 hz or there transformer are so we only need to activate the transformer , maybe it would be really easy to get those to work , maybe start with a light bulb...

It seems you already have it working. Have you checked to see how low the battery voltage can go?

@ jeanna

I found a data sheet. It says it should work at 0.35 volts for sure and maybe less. Specs look OK.

@ jeanna

You will probably need to increase your base resistor value for the EB because it can not supply much current.
