My Digital Pulse detector Delta Pulse 3

Hi all,

a month ago or so I received the kit, and I have some doubts.
Can anyone help?

1 - I think the R43 of 49 Ohms is missing.Yet must be of 49 Ohms? Tolerance??
2 - Look at the R49 and R51. One is 5K6, but the other seems 4k7. Are be equal, 5K6?

3 - R52, R53, R55. I can not put this resistance in vertical, the wire is short.? Can I solder a piece of wire? Or do I buy another?

Thanks folks

HI ALL

can I replace with BU406D/BU426A/BU508A/BU807


thank you

Hi pigeon
-U can not replace with [BU406D/BU426A/BU508A/BU807] its TR.
-BT169D its SCR.
---For assist Download datasheet of BT169D & replace it In relation to the V,A,,With Note arrange of pin K,G,A

Hi Biogas
-try with Coil-Calculator to test the table.

Hi Jap, hi All!

I have got a table about a PI coil:

http://www.lammertbies.nl/electronics/PI_metal_detector.html

These coils is good for it or not?

Ø 120 mm	Round	36	Ø 0.40 mm / 0.14 mm2	405 µH	1.9 Ohm
Ø 150 mm	Round	31	Ø 0.40 mm / 0.14 mm2	394 µH	2.0 Ohm
Ø 175 mm	Round	28	Ø 0.40 mm / 0.14 mm2	387 µH	2.1 Ohm
Ø 200 mm	Round	26	Ø 0.40 mm / 0.14 mm2	406 µH	2.2 Ohm
Ø 250 mm	Round	22	Ø 0.40 mm / 0.14 mm2	380 µH	2.3 Ohm
Ø 300 mm	Round	20	Ø 0.50 mm / 0.20 mm2	390 µH	1.6 Ohm
Ø 400 mm	Round	17	Ø 0.50 mm / 0.20 mm2	396 µH	1.8 Ohm
Ø 500 mm	Round	15	Ø 0.50 mm / 0.20 mm2	400 µH	2.0 Ohm
1.0 x 1.0 m	Square	10	Ø 0.66 mm / 0.34 mm2	406 µH	2.0 Ohm
1.4 x 1.4 m	Square	8	Ø 0.66 mm / 0.34 mm2	387 µH	2.2 Ohm
1.8 x 1.8 m	Square	7	Ø 0.80 mm / 0.50 mm2	398 µH	1.7 Ohm

They are corrects? In CAT5 wire whitch is the diameter of the Cu wire? 0,50mm?
If they correct is, than correct your 0,4m coil plan? (3 turns CAT5, 3X8=24 turns, and here is don't 24turns, here is 17 turns)

Thank you!

Biogas

Sorry, If I was don't unequivocal ...

for Q8 z0103 MA, don't BT169D, and for Q3, Q4 B108 don't 2N7000! They are goods, or doesn't work it with?

Hi Biogas
-z0103 MA rong its a triac
-B108 rong

Hi All!

I have got in store for Q8 z0103 MA, don't BT169D, and for Q3, Q4 B108 don't 2N7000! They are goods, or doesn't work it with?
Thank you!

thank you Jap

I will try

[jap]

But it works very late and very short wave.
I think that the problem is on the coil.

thanks

Hi volcano
--good for success.
--for the delay in the start-change vd12, C22,C24,C28.
