Delta Pulse

Hi jap
I used cable 8x0.5 mm, 3trx8 = 24 tr , R=2.7 H= 0.555 mH
It work good now.
What do you think? of this result box coca cola detected at 25 cm
What is the nobre to turn for framework 1x1m with this type of cable?
Thx for your help and knowledge

And the frequencies? My work with 400 Hz and similar coil (40 cm, UTP cable CAT8, 2,8 ohm, 500 uH). With 100 Hz the IRF warmed. I changed 740 to 840.

Hi Szucs_g
But 400 Hz is not good for depth
The good is 130.....170 hz
If is warmed little no problem but not so much hot

decrease PULSE WIDTH at its minimum to 100 microsecond. add a resistor and electrolitic capacitor in SOURCE pin of MOS-FET according the DP schematic.

Hi Jap

Testing the points A,B,C and E for connecting the LCD
I found the following values:
A=10.28V
B= 8.74V
C= 7.42V
D= 0V
E= 12.44V

Is this normal after you? is what are the exact values? and how to find them?

But it works normal same with C25=224nF 630V because I do not find 63 or 100V in the market.

Hi Nicolas
-R5= for small coil 20cm ~ 50cm use 680 /1w ~ 1.2k/1w
for pig coil 75cm ~ 1 x1 m use 1.2k/1w ~ 2.2k/1w
-u get good stable .
-you can replace R5 by variable resistance value 5k and then set to the best mode and then reading the value and placed of resistance instead Equal to the same measured value.
-for 1x1m=4m cat5 same ohm,uh

thx Jap
Ok I understood

OK! But my first coil with 28 cm diameter and 450 uH. It view my gold ring about 24 cm distance. The new coil work fine with this parameter (coil: 40 cm, 540 uH,3 ohm) - 380 Hz, 680ohm/1w dumping resistor. It view our iron stove from 1,3 m of distance. I prepare a switch, with which it is possible to change it, the dump shirt resistance and the frequency.

It correct information. I save it in my notice! Thank You, Jap!

Hi Jap
I use a 0.8 ohm 1w speaker but the sound is low
I can change it with another 0.8 Ohm 0.5W
or I have a problem somewhere
I need your help

Hi Nicolas
-Leave the speaker 8 OHM as it is because it is better.
-Be sure that your speaker is connected between the two pin 3-2 in J2(IN DP2).
-Be sure VOL=100 OHM=1K POT,R46=2.2 OHM
-To be safe change C27,C29.

Hi Jap
My connection is correct and my component
electrolytic capacitor 100uF and 220uF 50V the R46 = 2.2K
I use this PCB
But I have this problem

[jap]

Hi Nicolas
-Tested and check T9,D8
-Tested all the components and value in its place ,like r44=330 ohm,,And so on.

Hi Jap

I tested all no note all values are correct
I have not managed to locate the problem
But with the headset is good it works
I think only replace the Cap 220uF 50v by another 35V

Thank you same as

Hello everyone
because these days I have time to spare I decided to help a bit in making KT315 PCB PCB work the first time and do not forgive if I did something stupid. I hope to finish the kit today and if you have any objections please say to make it right. I think KT315 will criticize me a lot because I play his mounting interface
