Mineoro 2-Box -- 492 feet range?

Also I think I may know where this patent is.

Regards.

And this unbalances the equilibrium.

Can work, but IR helps a lot.

Anyway, all the resistor values are missing.

OK, Man, good work, very nice. our eyes is on your abilities to translate it to a usable and brief form. now I'm somehow confused that surely some others are so.
again especial thanks for Morgan, Esteban and thanks for other diligents; Qiaozhi, Max. god bless you all for your efforts.
If all details be reflected exact right and be combined with your efforts will become a great unforgettable memento from makers.

Before was 1,2,3,now its 4,5,6.

R13 = 470 ohms, 5% tolerance.

Now - with circuit #2:
R2 = 82k, R3 = 27k, R5 = 12k, etc.
But - R1 has 5 colours (not including gold, which is the tolerance) and R4 only has 2 colours. Please can you recheck these? Either 3 or 4 bands + tolerance is normal.

Important note:
R1(circuit2)
R5(circuit3)
R1(circuit6)
are the same(red,brown,red,black,white,golden)
You can see one of them in the center of this photo.

Hello Fred,i already put some corrections about resistors in PCB 2,3,6.
Unfortunly i dont have permition to open the antenna,but i think if we have some genius here,we can build and put to work this device.
I saw carefuly the Antenna and didnt find any Infra Red,maybe its inside...

[Fred]

I hope esteban can help about the "antenna".

Here is the PCB2 reverse-engineered.It may contain errors of course.
Regards,
Fred.

max, you certified me?

circuit 1 regulator
circuit 2 modulation and filters?
circuit 3 amplifier?
circuit 4 sound tac tac
circuit 5 preamplifier?
circuit 6 oscilator

Hi Morgan,

Please could you make an in-circuit resistance measurement of this resistor? It's probably a 2.12K resistor. This particular colour coding is unknown to me.

Hi Morgan,

Please could you also check the connectivity of the wiring to the antenna, i.e. what is the resistance measurement between the different wires?

I have completed the reverse-engineering of circuit #5, but some visitors are coming to my home today. Hopefully I can post the result in a day or two. So far I cannot see any evidence of a 7kV generator. It looks more like a receiver to me.

Morgan - one more request -> please could you also do a connectivity test on the ferrite cores. i.e. what are the resistances between the wires that go to the coils?

Clue#2: Some EPCOS electrolytic capacitors.

Maybe there isn't... And it's in fact a second regenerative coil.

Hi Morgan,
from what I know that color scheme have no meaning :

red,brown,red,black,white,golden

You have to recheck it cause it's maybe as this:

red,brown,red,black,gray,brown

If so , resistor values are :

2120 ohm 0.05% (tolerance) 100ppm/°K (temperature coeff.)

Kind regards,
Max

Hi detectoman,
we need all schematics to say better ...but that's my idea...

I think:

PCB1 = voltage regulator based on LM317 IC
PCB2 = rf mixer
PCB3 = rf preamplifier ?
PCB4 = square wave oscillator (that probably drive TX coil)
PCB5 = regenerative crystal demodulator ?
PCB6 = threshold detector and led driver

Kind regards,
Max

[Max]

Hi,
this is pcb1 schematic and my calculation gives exactly 9volts output for it: so at middle of battery voltage when they are at full charge.

So know we know that circuit works at 9V stabilized supply.

Kind regards,
Max

Imputing the code gives a value of 212 R./ 0.25%

I speak with Alonso and he told me there are IR, maybe not in it, maybe in other variation/modification of same pistol. For the same reason old PDCs don't have IR and other modern PDC contain this.

In few time I'll have access the schematic.

About equilibrium, this is the adjustment in the best sensibility point capable to be dislocate for the signal received by the IR.

Hello
I take out resistor and the measurement 18.09 (using 20kohm),so its something like 18k or 19k.
I hope we discover all electronic mistery aroud this device...

Hello
This is more complicate because for acurate measurements i must take out all the 7 cables who goes to antenna,i already glued all the circuits into wood box...
We will see,i will do this if Esteban cant help us with the Directional Antenna.

Kind regards

[Morgan]

Hello
Its 18k or 19k
