Hi everyone,

   What do you guys recommend for winding a 60mm Jeanna toroid core?  I've got cat5 and phone wire, and some heavier mag wire if needed.  # Turns?  I found this image below, earlier; Is this it?   

Thanks in Advance,

Hi sirmikey,
That is a good one.
The toroid is so heavy it is nice to use the thickly coated phone wire. I thought that was the same thing as cat5 or cat6 wire.

I have also used mag wire for the pick-up in  JLJL
As long as you do not scratch the insulation you will be fine.
Did you get this 2 1/2 from mouser?
People keep asking me and I do not have a good answer for them.

I found that 2T,8T was the best tuning for the primary of the 60mm one I had from MMI with the W permeability.

this is a recap of what i can do with 1 aa battery as it stands right now ...


the ALI 4" and the ALI 1"  togather in 1 unit ... 

i can charge a boost cap in 2 min or less from the aa driveing system ..

useing 1 2n2222a and 1 2n3055   

the unit i just showed and the ALI coil  bifillar 1 inch ..

btw i know this will RUN ON A EB OR EEC  .. as long as it is capped and maybe on a photo cell to run at night when the solars dont ...

WithOUT taking away anything from those wonderful folks who are using the cell phone charger, I do want to point out that 5.5v is the same thing as 4 NiMH batteries.

Also 150mA x 5.5v =825mW

where

150mA x 1.2v = 180mW

So there is a major difference in power IN to these circuits.

thank you,
