hi the software used is Proteus so I do not know if that is compatible with cad most of the components are already smd on the red board the blue board should be redone at some point.

Hello johnny23

Thanks fro informatons.

I am specially interesting in SD2000 oscillograph envelopes in some important test points and timing settings. Once we have take all valuable informations out of SD2000 detector we can put it in new design like complete new microcontrolled SD2000 PI machine with newest components and stuffs like digital filtering, new kind of discrimination processing and visual postprocessing on large TFT display. My idea is to take best of CLONE PI and CHANCE and mix it up with SD2000 or upper model timings. SD and newer Minelab nugget machines have instrument base at very-very fast low selfcapacitance coils with very sharp rise and falling times of ground penetration impulses. So in my oppinion we should make some mods with newest power MOSFET and IGBT drivers for very short delay charging/dischargings input capacitances of Cgs (Cge) MOSFETS (IGBTs) and cutting internal (parasitic) shunting zener diode between drain-source (collector-emmiter) to rise amlitude of fly-back (kick-back) impulse several kilovolts high with great density of magnetic flux around the coil. Another variant is use of DSRD diodes as a source of very high voltage and current amplitudes impulses. Rise and fall times are in picosecond domain. In PI we must have very high transmission COP because the power of penetration impulses very fast falling in ground with 1/ r↑2 (sqaure) radius from coil distance. In salty soils and highly mineralized grounds it even falling with 1/r↑3 or even 1/r4. Finnaly it means a lot of digital noise and very bad distances in prospecting areas. If somebody have idea how to get 1/r attenuation of target signals I am listening him very carefully. Maybe some new design of prospecting coil or some new principle/s of metal detecting.

Thank you very much for your interest in my master ne555. like I said, I don't know a lot about my pi. how much voltage and frequency on the circuit where you should see information you have and thank you very much about the title of respect
