Hi.
All these years i received so many mails to post the schematic of Andy Flind.
Today i decided to post it here.
Article is in PDF format and it is from EPE magazine.
I would like Admin to tell me if i can do it or No. Article is from year 1995.

Regards

We waited for this moment for a long time, thank you Geo

Geo, first post, then ask.

Admins post a lot of old magazine projects here:
http://www.geotech1.com/cgi-bin/page...e=projects.dat
so one more (22-year old project) could not change nothing.

In contrary, admins can delete post (after most of member downloads of course).

Hahaha.... no good idea.
I want the members to read the article and these that would like to construct it with modifications. Maybe i am not sure about results.... but they will construct a lrl the same with a commercial one (and very expensive).
So i need the permission of Admins.
I am waiting for Qiaozhi......

Carl says that Winborne Publishing gave him permission years ago for older articles, probably including this one. So please go ahead and post it.

Also, while saving the PDF from Geo, I discovered that I had this article from Andy Flind dated 2001:

Thank you Geo and Qiaozhi

What gives this peculiarity in this magnetic detector ???

Mike(Mont) · #18 01-10-2018, 02:31 PM

Thanks for the info.

There is a cell phone app titled "Tesla Meter" the icon is a power pole. It has an AC magnetic field detector as well as DC. Don't expect it to be nearly as sensitive, but it's cheap, like a dollar or two. Or do a search for EMF detector. You can even find reviews or which is best.

If you mean the Andy Flind then you must search at forum.
Esteban made some modifications and make it a good lrl (as he was telling).
The good is that you can construct the schematic as is (on original pcb) and later to make the mods and maybe the adds. In place of T1 you can use a tuned coil.
With little mods on it there is a very expensive lrl (don't ask me if it works

)

The app is called Tesla Field Meter by JMS Solutions. Of course not nearly as sensitive.
