Introducing myself and looking for help on making a coil for the first time

A good down and dirty source of wire for your coil is a Degassing Coil from a trashed TV. Most are made up of the required wire size. 26 - 20 AWG . Unfortunately some use Aluminum wire now and still usable but a pain in the Butt to terminate .

Hi, thanks for the reply, but my questions are on post number 10, the questions regarding wire size are now solved.

SVGA,VGA, EGA, any CRT type, monitors have the Degaussing Coil too.

Sticky foil is OK for a basic coil, I've used that. If you want to build a really aggressively fast coil then you'll need something else. Wrap it completely, except for a ~5mm gap between start & end. Usually where the wire pigtails are at.

Hi, thanks, I've done that and when testing the tx circuit I could hear a tone without putting a speaker close to it. Then I put a 8ohm 0.5w speaker close to the coil and it kind of sounded like a little bit more, but I wasn't sure if it was really inducing something... So I tested the speaker terminals with de multimeter in the lowest AC scale and when putting the speaker far from the coil it measured 0.00mV but when I putted the speaker close to the coil, it measured around 5.XX mV. Did the same test without the aluminum, and same result. I guess It's working.
