Hello Belief
Try reducing R5, 680 ohm (page 33, post 823) to 400 ohms or less

'if anything does not go via a head... it will go via your hands without doubt!'
try again. take FAT diameter in good isolation. i used 2,5 mm multifilamentary-twisted-stranded wire what I could be find around...

nobody here suggested to use tiny diameter for hypercoil

Hi, Belief
There are too much turns, I think.
I made frame-coil 1m*1m for my PI, by 12 turns of wire 2,5 sq.mm.

any of them will be OK. better in order - 082 than 072 than 062, so 082 is best in your list.

in theory PI mashine is really more sensitive to ferrous metals, not to gold. it is normal. let gurus in this forum to give you more detailed report on this matter... if you so need in the theory and patents... mine english is not so applicable for longest extensive structured cool&hard classified answers you could be hope. i am more a practician than theorist...

good luck
