IB Re-Design

I love it when people play with my electronic designs. I study with fascination what they did. One of my innovations was to convert Induction Balance (IB) metal detectors from analogue to digital, which caused quite a stir (at the time, in 2002, all IB designs were analogue). In November last year, Mirko Pavelski of North Macedonia did a marvellous re-design of my original digital design, and did some great testing at 3:30 minutes into the video. His re-design is just a bit power-hungry, and probably (like mine) suffers some drift. https://www.youtube.com/watch?v=1i1-bqcrFjQ OBSERVATION: I have seen several videos on the Internet which play with my original digital design. I sold the rights back then to Silicon Chip.

POSTSCRIPT: Pavelski's re-design in fact improves stability (less drift).
