your wellcome
good luck!

Thanks Jose , kt315 also alonejax from guilan

hi matrix
dp 2 is a good detector
you can use 12V7A battery for that
thats normaly current is 150ma
good luck!

sensitivity = pump out pulse WIDTH (POWER), that you see on old schematic called by strange word NOISE. try maximum value 500us for to increase the sens.

Hi all
I have a question about NON-digital DP .
what is voltage maximum value?
Is sensitivity or depth of device depend on with voltage value ?
how much can we increase it ?

Regards

Delta Pulse was designed for 12 Volts.
I try to give more tension, 15-16 Volts, but stops working.
When the low battery voltage, the sensitivity decreases somewhat.
Use fully charged batteries, is the best option.

thank you nicolas
is your detector dp2?
when you use with coil whats you fereqence?
your R5 & R6 is 680 & 1K ?
thanke you

if for coins tune first strobe delay to 10...15us meaning preset of MAIN DELAY pot.

you are the crazy lunatics there guys... you are fantastically contumacious guys trying remake DP to hunt coins... written many times, thousands times, DP is not for coins, but you again and again try to lead DP find coins... CRAZY WORLD!

damping resistor is like a tuning matter. look at this illustration.

for deeper you can not increase PPS - there is not a frequency in PI, there is only PPS, Pulses In Second, because PI, - because you should economy your battery reserve.
try to increase to 300 PPS and you will get Sniffer XR71, if you are so experemental guy. 26 cm is not a coil for deeper, because deeper. deeper is working with big coils, because deeper.

Thank you kt315, I will try. I need a coil for small items,, like a coins.

What value damping resistor should have for 26cm coil, wire 0.45 mm, 35 turns for better results? Which is the best frequency for such a coil?

tahnk you porkluvr

any body can to make adc(analog digital converter) for use in delta to sence betwin gold & metal?adc show change voltage or frequency or current to graphic per cent in lcdcan make with avr or pic or .. micro procesor

you may be have to look in QED side if want an explicit detector on gold. this subject I mean Delta Pulse is not for you and leave it. Delta is deeper working in all metal, has simplest in realisation schematic.

how i can to make big & good coil example 1m*1m
if i make that , i must change damping resistor?
flat coil is better or normaly coil?thank you

Look it


I use cat5 for my frame 1mx1m 2turx8 = 16 turs is good for me

and for my coil 36cm 6.1Ohm 459uH it is Best deep 90 cm for a printed circuit plate
20x15 cm in cooper

how i can use pr1-9 pin in delta board?

Like signals get connected to like signals.

For instance:
TR1 = TR1
TR2 = TR2
TR3 = TR3
and etcetera.

"Shorthand" schematic notation so that the designer would not have to run signal wires all over the place, looking like a bowl of spagetti.

I would like to see you (or anybody) try to make a 1m x 1m flat wound coil. That would be a neat trick, but a waste of time.
No, don't mess with spiral wound coils until you become expert.

A 1m x 1m rectangular coil has been described here many times. Yes, depending on what coil you use a different damper may be required.

You might try:
10t 0.35mm wire PVC or Teflon insulated wire. Not magnet wire.
1m x 1m rectangular form
result:
~450uH, 7 ohms (these are wild estimates)
>40.2m of wire is required.
If your current damping resistor works with the coil you described earlier, it should probably work with the coil I just described.

The problem with what I just told you is that, wrapping the wires tightly is necessary but becomes difficult with a large coil form.
Some people like to use Cat-5 wire and splice individual sections together. I can't really help you with that except to tell you that it has been described before, do your research (google.com search is good). READ previous posts in this thread.
