Finally the pictures could be displayed, though the sizing seems terrible.

Please help to verify my findings...

bs2012,

I did  fix the scaling of your JT drawings, thanks for the post and welcome to the forum. :-)

Please go here: http://www.irfanview.com/

and download the irFanView program. In that program you can scale your drawings. So if you make a drawing
in say, Windows paint, then you can scale the drawing in irFanView and convert the drawing to gif or jpg before
upload to the forum.

Download Apache OpenOffice:

http://www.openoffice.org/

Make your drawing with the easy to use drawing program.

Save the drawing as PDF using the little pdf button in the top bar, to your desktop, or wherever is easy to find for you.

Convert the image from PDF to JPEG using PictureResize:

Resize image from JPEG to PNG using ShrinkPictures:

Set quality to best, experiment with best resize for upload display.

Have Fun!

or... if you don't want to or cannot download programs, goto  www.pixlr.com  and use their web-based graphic editor.

Thanks everybody for your kindly assistance.

I am eager to look for somebody to replicate the circui and to verify its efficiency.  I do not have any scooe to test it...

@bs2012 :
It looks to me like another version of the "ghost light". I've found that if the oscillation frequency is high enough the LED will glow dimly, even with one wire disconnected and no earth ground connections. Touching fingers in various places makes it get brighter or dimmer. Current drain is low when this happens, and it's difficult to scope because the system interacts with the scope's ground lead and even with the few tens of pF of the probe's own capacitance. I don't have coils of the specific turns ratios, so we know who "will be" rolling in his coffin if I try to do any work with the coils that I do have.... but I'll see what I can see anyway. Thanks for posting the images and getting them cleared up.


ETA: Irfanview is a great program, it views images and movies and even text files of all kinds, handles .tiff files fine, etc.
