Jeanna:

Thank you for the gobrushless source.  I remember that you found a good source of mag wire but I am very glad I don't have to go back to try to dig up your post from "the archieve".

Crowclaw:

Jeanna said it perfectly.  We certainly welcome the folks with real electronics education as it helps to keep us on track without reinventing the wheel so to speak.  XEE2 has done this for us many times and so have others.  Also, as Jeanna said, an open mind is a good thing.

Jeanna has been on us from the beginning to keep track of wires gauges, transistors, resistor ratings, etc. and post them along with our experiments.  She has always done this.  Now, speaking for myself, I have become better at it thanks to Jeanna's suggestions, but I still have a long way to go.  I do document my experiments via Youtube videos pretty well, but again, plenty of room for improvement.

We are glad you are here.  Anyone dedicated enough to read the past many pages for hours and hours and hours is bound to be an asset to us all.

Hi everybody,
I just had some good fun!

First
20wcfl+7wtube in series.
then
20wcfl+15wtube in series
and finally
20wcfl+20wtube in series.

My first experiment with my newest bulb.
The  last pic is the newest 20w tube.

OH also, this is with a TIP31c I am trying out from allelectronics.
It looks good to me!

The 20w tube growlight is a very cool sweet barely on but it IS on.
So, that is a total of 20w+20W= 40w
I kept the cfl on and added the different tubes.

Have a look:
edit.. compare the size of the tubes to the breadboard.

This is the new 20w F Tube by itself running on the Big Gold.

Mag wire scroungers ,when ever Im looking for wire i go to the local electric motor shops where they repair commercial electric motors and offer to purchase the left overs at the scrap price which is what they sell it off at to be recycled with the wire they shred off burnt motors.
  Im not talking about little bitty radio shack size rolls.The rolls I get still have many pounds of wire left on them sometimes they have 15lbs left on a roll.The rolls are really big honking ones like the type you would see used to stock rope. Plus these shops also save caps ,stock cap, collect caps. Boxes and boxes of caps of all sizes. The place I used to go to sells mixed boxes of caps by the pound.
  Check out your local electric motor shops.

@ guruij

I used UTP network cable, I think it is 0.5 mm. You can use 0.3 mm as well.
Made these today with 0.3 mm run on half of the batt pack and charges the other
One 10 mm toroid out of a Ikea CFL and a 6.5 mm toroid
Going to bed now
