My Digital Pulse detector Delta Pulse 3

[erdin]

it switch's on but the button does not switch it off again. i have to keep disconnecting the battery is this what you are doing as well?

[erdin]

now when ever i switch it on i get a message saying ''bobin takili degil'' which i think means coil is unplugged but it is actual pluged in? and nun of the other buttons work? it was working befor?

Hi erdin
-yes its Another sw to off.
-a message saying ''bobin takili degil'' its normal test ohm ,uh of your coil.

Thanks jap every thing is working but i can not get tr1 to give 6.22v at pin 5 of d6. What do you think

Hi erdin
-1-test , change D4,D1,D6 AS PDF.
-2-IN MODE scope use tr1 for calibration.

@biogas,
take care, that the controller of the GLCD is KS0108. There are other controllers on some GLCDs that dont work with programmed pic. I bought one at ebay as mini 12864, which has this controller and its size is only 54x50mm so that it fits in several boxes. the other "standard" displays i would have to mount on the top of my box, what i didnt want, hehe. Mentioned GLCD costs 13 Euros incl. shipping.

Hi!

Where can I that buy it? Please post it the netstore!

Thx

Biogas

Ok, thank you! (Vielen Dank! )
It has light on/off function?


Battery
Wich battery need this detector? 12V? For example 2500 mAh 10 x 1,2V AA battery in pack? Or?

Switch
I would like build a" water/drop/splash" proof detector. Witch switch are the ideal for it?
I think it's don't the best for it!!??!!

Coil
I would like build about a D40 coil, and a 1x1 frame coil. Which properties have they coils (wire D, numbers of turns, industance, resistance, etc)?

Schematic
I don't find a high-resolution picture about PCB and schamtics. Have anyone?

Many THX!

Hi jap, can you expline a litle what you mean by ''IN MODE scope use tr1 for calibration''

@ Biogas,

the LCD has a backlight function at pin 19 and 20, which is controlled by the PIC18F452. So when you push the main switch on, after initalize the backlight turns on.
I power the MD with an external power supply (12V and 7,2 Ah). It is your choice how to assemble it.
If you want to have a water-drop-splash-proof MD, the box, the 5 control buttons, connector(s) have to have these specs,too. Even the common LCDs do not fulfill this condition.
The level of protection you mentioned is about IP64 so i would search for this in the technical informations.

I built my coil like this:

wire: 3meters of CAT5e (standard ethernet)
turns: 3 (diameter about 31,8 cm)
inductance: 473uH
resistance: 3.6 Ohm

Generally resistance should be in 3-4 Ohm range and inductance 400-500 uH ( i also read 400-600 uH).
The PDF docs in the author´s forum were good enough to etch the PCB and see clearly all components, at least for me.

Hi jap,

thanks for your reply. I watched the video but i dont understand how it will help me set tr1 up?

[jap]

Hi erdin
-RE,in MODE scope u can adj. tr1 for calibration.(to get the Curved u see)
-test , change 2n7000, D4,D1,D6 AS PDF.

Hallo!

Thank you the response! It was useful!
Have you finished your projeckt? Can you share photos? If not, than tooo! Thank you!

I have problem with the LCD light: in our country must/ recommended/safe detecting in dark/night, than I don't need the LCD light...

This D30 coil I think it is to small for me , than I would like a bigger coil! (Have you tested this D30 coil?)
Have anyone technical parameters for D40 coil,and for 1x1 frame coil? (turns, wire typ, etc) (I see: 3-4 Ohm range and inductance 400-500 uH)

Where is the conecting points the coils and between the PCB? "Bobin"? Wich plug/connentor need I to? 4 pin, 5 pin, or a special?
Under LCD are 2 resistor whit RX value, what are they? If resistor, wich value need I?
I found good PCB and schematic....... in my folder...

And I would like buy the parts, but I don't have the real part list,have anyone?
I have a plain,but this have a lot of imformation, and I would like see clearly for example:
- C1 18 pF...C39 100 nF
- R1 4K7...R91 1k
- ...

Or:
Resistors:
-5K6 11piece
-1K5 5piece
...
Capacitors:
-47 uF 5 piece
-10000 uF 2 piece
...

Many thanks!
