For sale bare boards for Delta Pulse/Sniffer XR-71

[kt315]

not.

you use probably one layer coil calculator. you have choice several layers.

then you have to operate by:::

core length
coil depth
core diameter

Are you author of this document?
What is the "Length" of coil used in these calculations?

[chuubaba]

No.

do you need screenshoot of my message in what i offer you to buy HV diode together with board?

[chuubaba]

Is there a hospital and a school near your house?

[kt315]

i many time answered on this question.

600v 15a hyper fast....
---

1000V -!!! you must seek 1000V >=12A one.

[kt315]

you refuse pay for:
- high voltage diode
- DVD with archive
- operational amplifier tester board

close by a jumper the pins of the diode on board and forget it.

Stth1210d not in my country.
We have by359f-1500 schottky rectifier and rhrp30120 600v 15a hyper fast....
Can i use these?

note from the report

[kt315]

yes, in this day september 8, 1942, my grandfather was dead in Stalingrad battle. he was a tankist tankman.

learn classic work with ramka coil at field. those guys are seeking at field of great battle nazy vs soviets Raboche-Krestianskaja Krasnaja Armija, RKKA, in Stalingrad city.
in result big army group of nazy Vehrmacht, under control of Friedrich Wilhelm Ernst Paulus Field Marshal, 300 000 soldiers, was surrounded and surrendered.
on this time USA did help Stalin Jozef Dzhugashvili and his bloody despotic sovetic regime.

i hope you will seek the treasure. job with ramka coil in winter is hard. DP seeks very much metal on bottom of the lakes.
main problem is how to lift that up from 2...3....4 meters of deep, not to find something on bottom. search magnet does not lift big metal.
you have to plan where seek the treasure, not me. i went all this way.
i use 1x1 m coil. people asked me about how to do small coil and i did it. for bara.








now i do not have working DP and do not ask me about hunting. all boards were released. DP in pics was sold much years ago.

[chuubaba]

Have you used this metal detector yourself? What size coils you used? What treasures you found?

[kt315]

my board is projected under RV09 type pots 'horizontal shaft' but i noticed people do not want use them.
main problem there is not 500k/470k value one.

Do you recommend metal body and shaft or plastic ?

places/placements of the pots on board are universal. you can use any pots with 5/5.04mm or 2.5/2.54mm pin step.
with metal body pots you have to shield them by one naked wire soldered on their enclosure.
my albums show that way.
you can choice pots with long shaft or short, how you want.

What is size of Connectors for battery and coil and speaker?

i rewent into more popular novaday 'screw Terminal Block Connector 5.08mm Panel Pcb Mount' because people
set it while my board was done not for them. i must go in direction what people want.
i bought them for to measure their sizes because i did not present what it is.

for speaker i use desoldered connectors male-female from oldie pcbs.

sometimes you have to learn to use active flux for connectors, to irradiate pins and wash its by alcohol before you will place the socket on board, because
steel maybe not covered by the solder, meant naked steel.

chinese always economize on:
1. copper
2. any material
3. steel
4. nickel
5. leave the connectors pins without solder cover

at first you have to attempt to solder IC socket pin and if you notice it is not soldered then use active fux. irradiate all pins, wash them up by alcohol,
just then set the socket on board.
another way you will get big problem, unsoldered pins, and the painful headaches.
