PS - Great to see someone doing something besides critisizing, and condeming what some else's ideas. Real progress we all hope for!  |
Perhaps it depends on the "real" test results if I publish the schematic.
And maybe also if someone really knowledged is willing to analyze what the circuit does...
Because I'm not completly shure about this - seems it uses some kind of resonance circuit that only establishes under special circumstances - resulting in this very sensitive threshold noise. That shortcuted emitter-basis connection of T1 (see above) also is very important.
Goldfinder, you're right, crizisizing is funny and easy, building such stuff alot serious work and "headache" if there occure unexpected problems - and those will...
Now I understand much better why some metal detectors are a bit more expensive as flat screen LCDs etc. Developing such stuff devours a huge amount of time, work and nerves...
