EER Joule Thief using an earth battery to start a joule thief.

[Pardon]

well the rewiring is finished on the eer cell. not good at all almost no mamps like .02 or .03 and the voltage is only 1.07  i will let it set a day and recheck it tomarrow. i think maybe the magnesium may need to touch more dirt. but the copper wire is wound around the mag with paper in between and the mag sticking out both sides.

the copper pipe i had been using is in real good shape.not to much corrosion on it. the fire starter block did have a small amount of ?? i really do not know what to call it. discoloration but when i scraped/brushed/washed off the dirt i could still read the original writing on the side of it. the worst thing was the striker rail had come off.

i would have to say my eer's have been in use at least 6 months. hmmm how long has it been since i was last posting about sea/water batteries. well i made these right after testing the water batteries. i remember telling a retired school teacher friend of mine, i have to water my lights every 3 weeks or so.

i was thinking maybe i would take another cell and try using iron wire wrapped around the magnesium. i really want to know what that would produce.

Is the paper very wet?
I think it needs to get started.
And, I also suspect the magnesium needs to totally touch the dirt

the copper pipe i had been using is in real good shape.not to much corrosion on it

that's good news

also good news about the magnesium block.

i would have to say my eer's have been in use at least 6 months.

That is a good long time.
Have you been using the magnesium fire block during this time too?

Doesn't it sound like there is not enough surface of dirt which is the electrolyte, touching the electrodes?
That is what it sounds like to me.

Please keep us posted.

thank you,

Hi everybody,

I measured across the 2 secondaries on Plant battery #1.
The results on that bigger pot and with a silicon diode and 2 secondaries is:
2^o #1 :
5.95v
222KHz
and for 2^o #2:
5.14v
222KHz

----------------------
I measured across the 1 secondary on Plant battery #2 as well.
This pic of the working plant battery #2 should finish off the information you need on this.
I took some readings from that red secondary.
The voltage is
4.95v at
125Khz
I am never sure if this is absolutely correct when the basic jt light goes out when I measure across the secondary, but this is all I can do.


Here is the pic of plant battery #2.
You can see the 6 base resistors, and if you look close, you can see they are twisted together at the bottom and so are shorted and there is no resistor there.
I do not get why this works or why this is the only way so far that it works, but at least it does work.

It looks like their is a lot of activity and EER Joule Thief experiments going on, with the weather finally warming up we have another season for trying out new ideas.  I'm following Lasersaber's lead and using mg ribbon south and copper wire north.  I now have 4 cells connected in parallel.  One cell works better on a single wire.  My cells are putting out over 30 MA at 1.7 V and now I am able to light two LED's using the basic Joule Thief circuit run a small motor and charge a 5 10 Farad and 1 50 Farad 2.5V supercaps to .83 V at the same time. Here is a link to my Youtube channel if anyone is interested:  http://www.youtube.com/user/dcspc1?feature=mhw5 I'll try to post a new video next week.  Keep moving forward.  Happy Easter everyone!

I am looking forward to getting 30mA from my EER.
Congratulations, dcc!

At the moment, my plant batteries are giving less than 8mA and I think the 8mA has gone down and is maybe 5mA.
However, the 2 plants have been running a light each for another 24 hours.
Of course, 1 bright white led is merely a night light. It is a pleasure to see 2 nite lights coming from the plants when I look on them at 3:00 AM, but 30 mA will be much more light.

My water with mg sulphate control had even less mA this morning and the ribbon was terribly corroded. It seems to be corrosion on top of the ribbon, and not below the normal surface, so it IS possible that the mg is getting precipitated onto the ribbon as the current goes to the copper electrode, but too hard to tell. If I scrape the ribbon smooth it comes to life again.
I guess I should look into some normal electrolyte uses again. In the morning there was H₂ on the magnesium ribbon ... maybe a little on the copper too, and a little shaking dislodged it and I popped the bubbles with a flame on the surface of the water.

The ribbon coming out of the soil shows no change at all.

So, ho hum ... another report that it continues to work for another 24 hours!
