Hi friends
What is your opinion for using plastic enclosure for Mineoro device? Have you tried it? Did you notice any difference in operation? Does it degrade the operation of the device due to the fact that creates more electrostatics than wood??
Geo i have noticed that my Mineoro needs some time to stabilize its output amplitude. It needs some minutes during of which the amplitude rises and i have to correct threshold again for stopping it beeping. As i see it, there must be a drifting due to temperature. LM317 is on a heatsink, so i suspect the quality of my electrolytic caps. They are not of the best quality. What do you think about that? Have you seen this again?

GEO's Mineoro DC2008
Hi.
Today a friend gave me a DC2008 to modify it. He wants to replace the sensitivity potentiometer with a multiturn one.
I opened it and i saw that the previous owner had open it and had remove the black resin from the receiver pcb.
Also i saw that there is a problem with the oscillator (2N2646).
So i said that it is time for a reverse engineering until i receive the multiturn potentiometer.
I Must tell that my friend found some small objects (ancient coins etc..) with it at small depth (10... 30 cm).
I attach some photos from it...
Regards
HI GEO
Do you have components values or high resolution pictures of both sides ?
What is exact stimulator frequency of electrostatic chamber?
2N2646 is an UJT transistor. It means very sharp pulses at output. Right ?

Hello Geo
I am well thank you.
Did you tried DC2008 without electrostatic chamber, only magnetic and electric receivers. Did he worked or not?
I don't agree with you about ions and IR light.The reason is simple - IR light haven't enough kinetic energy to ionise volume near the surface. If it would be ultraviolet light than yes. I don't think that Alonso have had ultraviolet leds in his devices.
Do you have HQ pcb pictures of DC2008 ?

Yes i tried without chamber and it was working ok. This is the reason that i believe that ion chamber don't do nothing.Originally posted by Dubulumach View PostHello Geo

About ir led..... who knows if it is a ultraviolet A or Ir?? UB-a is not visible (if i remember ok).

Brazilian theory was very simple and clever....Originally posted by Dubulumach View PostAnother logical variant about IR light and electrostaric chamber/s is that the whole Alonso's story about is "smoke and mirrors".
Construct a lrl with 2 or 3 different detectors inside. If one is working some times then we are ok. All the other will be good for difficult understanding.
A good way to protect their secret!!
