    A few spare minutes this afternoon. Agricultural Induction Annealer

    Got a bit bored this arvo so made a very Rough induction annealing circuit out of stuff lying around my bench.
    Built the coil from some scrap Coax cable

    Works OK, draws 5 amps in "standby" and about 8 with 223 case in the coil.

    Wanted to test it before buying a proper diy kit.

    With case

    Still needs work but 20 seconds in the coil will heat 223 case almost red hot.
    Need more work but looks like will work OK
