Delta Pulse

[labtec1]

Hi KT315
You're right that the IC socket solder very inconvenient at the top of the PCB and I have raised them since 5-6 mm above the PCB father to tip soldering iron and solder wire can approach the beautiful pin. Term I first soldered to the PCB and then I examine each in turn gave unimer has a connection with the underside of the PCB and then asking other components. DP is not ready to go when I got off the IR and over again repeatedly checked the socket and everything was ok.
I started to make new PCB because I have no more strength to checking by the leather which time all over again. In this PCB layout is the devil and should be entered instead of 12v lead the 110kV transmission line and expel it out. I'm going to hang this PCB on top of lightning during a storm, and then I'll see the result. Maybe some do so superDP running at 10m depth

follow this diagram and you must get and see these signal CLEARLY and BEING TUNING. it was got from bulgarian people but I had corrected the diagram to more precisely time intervals.

[labtec1]

the shematic no pins DA2 and DA3 pin 8 on the PCB are connected to the E-
this is good

[kt315]

at the schematic the power supply ICs' pins are maybe hidden. it is normal. but its are right connected to power lines. no mistake.

KT315 thanks for your answers and your efforts, I fail to revive this thing.
I checked NE555 (R43 and R42 without bc557) and got cited tone. So that's ok. Because we have an oscilloscope I took the speaker, poveao one end of the-12V and the other end went to check my order as described in http://www.geotech1.com/forums/showt...458#post129458
I have a ton to D1, D2, D3, but the other c either no or a very weak
I left the DP power and after 10 minutes he started to smoke lm556.
I replaced it and put a new and when I ulkljucio he immediately began to smoke
IRF is always cold.
What could be the problem and what should I check now?
another question
I'm about to start a new dp so I prayed KT315 to say which is the best for making and whether it is worth your danapravim xit revision of the PCB attachment
Thanks again for all your advice
blocks would be nice to meet you

[labtec1]

Attached pi.rar I finished all the pins on the IC so I'd like to ask you if someone can write what you where you need to go to the free pins.
If KT315 says it's worth it to try to come up with his shematic and PCB make this PI I immediately started to go pcb because I already lost the previous five days and nights, and I was unable to revive her. PCB has already started to fall apart for replacement parts!
When I was a few years ago made his first dp is working on now and then too, but unfortunately it TGSL been stolen when they broke into my car. The monkeys who do not know what is likely to serve
Now I am disappointed by the PCB and I want to make another
ask for help
Thanks to all the good people

Hello

I have little problem with my DP, when batt drop to 11.2V the red led is turn on-low batt. or I can use DP approximately 30min batt is lead acid 12V and 3.2Ah Irf 740 have normal temp.

Solutions ?

Thanks

[kt315]

decrease PULSE WIDTH to 250 us and measure the time again.

[g.s]

Hello. if time increase the pulse ΤΧ what follows we will, (I hope that there will be increase in power).
NIKOLOV check the zener VD15 9V1

[hitman]

Hello everyone . does pcb of labtec 1 (deltapi_v1_treiti) is with no mistakes.tnx

Hi Jap

I need your Help
Programming the PIC 18F252
I noticed this error
So I only lighting on LCD but no program

Note: The PIC used is a 18F252 - I / SP
becaufe the 18F252 - E / SO does not exist
What do you think? Error range of PIC.

Hi Nicolas
-The prog. Found within the HEX file a configuration and their work is done in comparison with the used pic.
-try to use another program covering values such as icprog106A
and see results, if similar not validity programming the PIC 18F252 - I / SP.
best time

Hi Jap

I thank you Jap the program to another program such Microchip. programming is unrolling correctly but still the same problem
The display is completely blank no program opens.
Against by a similatuer ISIS hopefully.
I try to program three PIC but no reading on LCD.
I think the Hex file is corrupt.

I ask someone who owns a file is good if walking with his detector can share.

Cordially
Nicolas

hi jap

I have built a 50 cm coil and it detected metals at 1m depth. is it possible to improve this coil so that it can detect metals at 1.5m or 2m depth
tank you , best time
