RELIC HAWK

Man that is confusing!!

Yes i used 2 and 3 to gnd, but U5/1 goes to U3/3 (via caps and res) instead of U3/9 , and U5/4 goes to U3/9 .It has no influence because control lines (U513 and 5) are connceted together.

well, at least i think.

Fred.

Hi,
ok I see, but sure change nothing: we use the 4 gates all togheter cause all control lines are connected to the same point...and ports are all the same... so we can change one for the other inside same chip... so no problem at all!

Actually... I've assigned that numbers to some of them who haven't... I can also change to accomodate schematic to PCB!

A reversed-reverse-engineering at the end!

What matter is at the end this stuff will fly...

Here we are: this is revision 1.3

Kind regards,

One step closer to final ?

Resistor=620K.Grt Nakky.

Resistor=620K.Grt Nakky.

Hi,
yes could be....
Looking at op amps there... I see the 820K is half of 1M6 there... so it's probable the unknown value is just half of the 1M2

If so there's already right there a "scaling factor" between the two channels...

Thanks Nakky.

Hi,
don't know if exact... but found these data about coil:

"
coil is 35cm DD coil,
RX=130 windings,0.25mm wire,on round former d=30cm ;42ohms,15mH
TX=35 windings,0.55mm wire, on round former d=30cm ;2.5ohms,1mH
"

Hi,
yes it is: 102u = 10 * 10^2 uH = 1000uH = 1mH

At least I read it as this...

(actually the u is a "K" but change nothing...K -> tolerance =+-10%)

PS: in the bulgarian schematic I see 1uH there... but probably is a mistake cause if it's 102k the only way it could be 1uH is if unit used are nanoHenries...

Kind regards,
Max

I would consider studying the possibility that it is 1 uh. Other ML detectors use 1 uh in series with the RX coil path (i.e. SD2000). I know the SD2000 is a completely different type detector, but ....

Hi,
well I'm not absolutely sure it's 1mH... but usually I read 102 as 1mH. It could also be 1uH inductor there... depending on units used for indication... e.g. if inductor is a small value one value could be also expressed in nanohenries really... though a bit rare option.

I now the great part of inductors are all similar about that and value is expressed in uH.

PS: I still think it's 1mH... but let's see other schematics too...

Kind regards,
Max

Hi,
It make sense to mee too that if it is marked "102" , (1000), that it will be 1mH...but as Max said can not be taken for sure.
I send here the completed (but still probably contain errors)PCB , with upper side layout.
It is was more dificult than expected to do, so it would be good if someone could carefully check it.To do so i send also the Sprint layout file,otherwise it is almost impossible.
My head is spinning already and i must make a pause.
I made only a very quick verification, so it may be missing some connections.
Unfortunetely, the +/- 2v5 connections to the pots still must be hard wired.I could have done differently but it would be more confusing , in particular for those who want to make it single layer.
Maybe that can be improved later.
Any suggestion is welcome.Critics too!

Best regards,
Fred.

Hi Fred Sprint layout 4.0 will not open it.Grt Nakky

RELIC HAWK

Nakky , Sprint 5.0 open's Relic Hawk perfect. If you need a copy of sprint 5.0 , I can e-mail to you...................Take care................Eugene

[Fred]

Yes Nakky, i have used Sprint 5.0.
A shame they are not compatible.
