Hello,
I have built Delta pulse 2 and have good detection with 40cm coil,0,5 wire.34 turns.I detect really well at distance...exept i get hot irf740 if go to increase gain more then half way up.
I have built also a 1x1 coil ,17 turns of enameled copper wire,0,5 mm.The irf740 does not heat anymore if i go all the way at maximum with the gain button but i don"t get good detection from it and i don"t know, it might be the number of turns? Should i try less or more for good sensitivity?
Kind regards
Marius
