Delta Pulse PCB error ?

Eugene52,

    I checked also the PCB top view post here by Ram and I notice that some of location of parts is already revised and I think the pattern side is different from my PCB ref.

Ram,

    Can you post here the patern side, so I can check the difference of connection, if you want. Thank you.

Eugene52 & Ram,

    In my schematic diagram ref. the potentiometer are:
P1 = Delay
P2 = Range
P3 = Pulse Width or TX Power
P4 = Sense
P5 = Threshold
P6 = Tune ( but in PCB is Speaker Volume Control "I think" )

    In Ram PCB are:
P1 = Signal ( Is this same function to "Delay" )
P2 = Sense ( In my PCB ref. is P4 )
P3 = Noise ( In my PCB ref. is Pulse Width or TX Power)
P4 = ?? ( I cannot read )
P5 = Tune ( In my PCB ref. is Threshold  )
P6 = Threshold ( In my PCB ref. is Spkr vol. "I think" )
P7 = ?? ( I cannot read also )

Thanks again.

vourvon

Everyone troubleshoot very slow !!! I went to the "FREE OPEN PUBLIC " website where Ram found more files and I am still trying to figure out the different versions !!! You can see on the board below that not all potentiometers are being used on the project in the lower picture . It seems we have 4 versions now . I am slowly figuring this out , the last version Delta Pulse you can purchase or maybe build from scratch has a powerful micro-processor and I am not speaking of the little pic-chip used for the LCD driver circuit from 2 years ago .

1. Mikron Delta-Pulse 1st version schematic very old had several errors .
2. Delta-Pulse mikron version errors fixed on Geotech and Russian Forum called version 6 schematic .
3. Delta-Pulse LCD version from "Elbombaci" was a good version and posted on U-Tube
4. Delta Pulse2 [new revised circuit board] has 7 pcb mounted potentiometers but not all are used on the board. [see photo]
5. Delta Pulse newest has PIC16877A-I/P that Ram posted and the hex file seems small. Is a larger hex file "only for sale" or is the smaller file posted for the LCD only . Who said something previously about possible discrimination functions ? Or are we being mislead ?

HH................Eugene

	Eugene, You can't really tell much from a HEX file. They're always as small as they can be when compiled. You need the source code to determine what is being done inside of the circuit. Even then, it can be very hard to match firmware with hardware unless you are the programmer.

Hello GoldDigger .

In most cases you are correct . The point I was trying to make was that a few forums over in Europe like Turkey Bulgaria and Germany for example have half of their website dedicated to selling Metal Detectors with colorful ads and prices and the other half of those sites is dedicated to an Electronic Metal Detector project Forum , how convenient is that !!  It first started over there when some self proclaimed business entrepreneur thought let's post all our schematics of our products on the forum here and the more advanced projects with good features we will have a few things missing , of which by the way "hint-hint" we can have for sale and if they ever have a problem we can sell some parts if we have to , like full version pic-chips or atmel's , or special expensive "PIU" chips . 

At least if we did that on our Thunting Forum right here or referred someone to a link:  We would state if it was for non-profit [at-cost plus shipping] personal use or we would emphasize that this individual or company is selling a product or programming for a living [Profit] . I am not against selling products on any Forum , I just wish all people were up-front and honest on how they do business especially on the internet .

Best Regards..........Eugene

	Eugene52 & Ram,     I see why have different name of potentiometer: This is for Unified Delta Pulse & Sniffer XR-71 Schematic fixed by KT315 rev. 6 P1 = Delay P2 = Range P3 = Pulse Width or TX Power P4 = Sense P5 = Threshold P6 = Tune ( but in PCB is Speaker Volume Control "I think" )     In Mikron Electronics Schematic Post by Ram P1 = Signal P2 = Sense P3 = Noise P4 = Gain P5 = Tune ( In schematic the name is Threshold  ) P6 = Threshold ( not in schematic ) P7 = ( not in schematic ) Please correct me if I'm wrong. Next week I buy the complete parts, which is better for 2 the Unified or the Delta Pulse only. Thank you vourvon

Hello Vourvon you have 2 choices . You can build my Final Delta Pulse project from the zip-file .
Or , you can build Rams Final Version !! You can send him a personal forum message [PM] to make sure he tells you which of his files are the best to use for the Delta PI . He is a very helpful Forum Member and a successful Delta Pulse Project builder !!

Regards...........Eugene

hello vourvon, kindly check this pcb, my idea is open the picture in picture viewer and zoom it then open the pdf file pcb and check if both are identical. in picture i got in commercial advertisement of dp it is for sale as a kit form. so,if picture is reliable then it is true pcb pattern w/c is operational.but i don't know if they make some jumpers or re routing via jumper in final assymbly.(only in my mind)also if they used other component values and quality in final assymbly.(only in my mind)

with regards to dp i successfully built, i tell u the truth, it is from eugene 52 file he posted from schematic to pcb. it is double sided pcb pattern w/out battery monitor and also the sprint lay file with software he send to me. in my 2nd dp i built w/c is i called "eu52 powerpulse deepsearch" i made some modification making the dp more powerful and beats the known pi md with mark "X" in actual test.i used 7ampere 12v mc mf battery it consume the battery in 3hrs contenous use.(monstrous in batt but monstrous in power)
regards,
ram'
