Pulse Star II first analog version

[ivconic]

Finally, after a period of testing and tuning: you can buy a fully functional PS2. All that remains is to pack it into the case and add the coil as desired.

I will order one later this week, how many mH and Ohm for the coils are needed?

[ivconic]

Original PS2 coils:

25cm coil = 1.5 ohms, 0.611mH
45cm coil = 1.9 ohms, 0.677mH
1x1m coil = 2.7 ohms, 0.361mH (this I am not sure)
2x2m coil = 2.5 ohms, ~1mH
....
Custom coil:
47cm coil = 2.6 ohms, 0.560mH
...
General guidelines:
1-3 ohms, 350-700uH, 0.4-1mm wire, depends on primary delay, damping R value, desired target size you want to catch.

Are there discrimination to this detector?

Are there discrimination to this detector?

disc part of the detector are two boards, one-on-one connected, floors. without them the project has not have big sense to begin to do, died.
so there must be 5 boards:
- main
- front
- rear
- disc first
- disc second

I just got back from vacation in Greece.
I will need a couple of days to rest from vacation!

Guys, Amigos...

Do not ask me about Pulse Star. I got it one time in a repair and had not a time to research it long. WITHOUT COILS,
i did erzatc socket female to connect mine made small coil. epoxy qlued. I do not know the type of sockets in the detector. not be agenda for me then was.
yes, there must be a jumper, Ivconic answered me on the matter.

pleasure

P.S. if you need good PI I will send you Delta Pulse boards without a delay, speedy. this is revision 5.0, last.

There is also a disc pcb in the original.
I left it out.
Because the disc with this detector is not reliable and serves more for "cosmetic" purposes.
Front and back panel PCBs are unnecessary.
Because the components on the front panel are specific and the grid and layout of the solder points will certainly not match the components that can be found in stores today.
Here I'm talking about a pair of potentiometers and a switch as well as two (or one) click-clack switches.
All this does not require a pcb for the front panel, but these components are connected to the main pcb with the help of wires and cables, very easy and simple.
As for the back panel pcb; it only has connections to the coil connector and all the rest of the components are for the battery charger, which has a conceptual error on the original and is prone to malfunctions and unexpected battery discharge.
Such a charger is bad and outdated.
That's why I also left out the pcb for the rear panel.
The coil connector as well as the power connections are easily connected with wires and cables.
Basically what makes the detector is all present on the main pcb and it works perfectly fine without the other pcbs.

New store, branded. And from now on it will be the official store.
