Has anyone built the DBP2010 pi detector?

[Darren in NC]

From Rolf Wilhelm's book. No English instructions are available. The original plans had errors, but some of the translated plans later corrected the errors.

I would LOVE to hear if anyone has compared the performance with the XR71/DeltaPulse. All claim to have discrimination with the large loop.

Best,
Darren

The answer is Yes. But that person is no longer on this forum. I will research from 5 years ago , when all the data was circulating. and try to post. Someone else may have info. I heard it was a Great Unit , with good depth. Eugene

Hi

Search in Yahoo French forum about projects by Rolf Wilhelm. In the forum, in the section Fichers, you can find the PCB of the DBP2010 and another PI's modifications: Stuart, XR71, Delta, VLF 770, etc., and another projects. First, think you require a Yahoo account (free email), and automatically you can access to Yahoo Groups in Yahoo main page.

The name of the Group is: ddm-elektor

Thanks, Esteban. I have picked that forum apart for clues. I can't read French and when I use the translator, it doesn't always make sense. I did find the zip file and opened it, but you have to know which program they used to open the files. Boardmaker 2 created the .pcb file, but I can't open the .plt file. Can anyone else?

Eugene, thanks for your response. C.Pruysers posted in 2003 on this forum about it. I have his info. If you have someone else's info, I would most certainly appreciate it. It seems as though there were errors in the original plans, but no one has a specific lists of those errors. I'll piece it all together with all the info I'm discovering :-)

Any other info would be great!

Thanks so much,
Darren

Fake....


I made it a few years ago...It failed to work, so i used hammer and "blasted"it in a very small pieces....
Later i heared that there are some intentional mistakes in design!?
Some resistor values are faked...or something like it!?
If i had chance to met "genius" who faked it....i would use that hammer on his head!

Anyway...it would be nice to try it again,only do not have correct values of
components....


regards


P.S.
There are certain people, who like to post faked schematics "for everybody to share" !!! Sick ignorants!

Hello Ivconic,

I hoped you would reply You mentioned a few days ago that you built another Delta Pulse and that you were going to sell your Pulse Star II because the performance was very similar. Did you find that the DeltaPulse, the XR71 and the DBP2010 are all basically the same detector in its design? Someone on a German forum stated this.

Best to you,
Darren

[ivconic]

Yes and No....


Delta Pulse and XR71 are exact the same(a few minor changes-not important)....but Pulse Star II is quite different. 2010 is also much different from others...

But all PI's have simillarities, stages and functions are the same.....What to say? It will need much more to say,but you already have here threads to read about it...
regards

Thanks for your reply. I gotta ask (everyone else does, but I've seen no real response) - do you have the schematic for a PSII? Has anyone "reverse engineered" it?

[ivconic]

PS II


No.I opened it,spoted 2 PIC 17C73's and than closed it for good!
Without .hex for those PIC's,aint much good from the rest of schematics,is nt
it? regards

[Darren in NC]

Ivconic - in my other thread on LARGE loop discrimination, Geo says you prefer your Deltapulse (which does not discriminate) more than the PSII (which does). Why is this?

[ivconic]

Disc....


It showed a very poor disc. I am used to dig no matter of type of metal detected....Besides man has to be proud on it's home-made!
PS II is excellent PI, you do not need to understand me serious....I can sell it for 2000e, while DP to build and finish it can cost me just over 120e!!!
So it is a sort of saving money....
Anyway DP is deep enough to consider it very serious...
regards

[ivconic]

Again dbp...


Back to DBP2010!
I just received strange PI detector!?
Sniffer XR 7 !?!?!?
Inside the box i founded DBP 2010!!!
Detector is in very good shape,working nice.Comparing to Delta Pulse
I can tell; EVEN....
Very good results on test field!
Excellent chance to check out validity of project documentation i already
have and try to find eventual fakes...
So i checked. On posted BOM every component value is accurate!
I checked all elements on pcb except those in black box,since it is glued/filled
with a kind of resin,which right now i can not brake,scratch or anyhow open.
Asume that misterious fake must be in that black box,cose every other element
value is trully quoted in BOM.
I made a copy of DBP2010 few years ago....it failed...I respected the very same
BOM....
Later,when winter comes,i'll have much more time to "play" with it.Than i'll
try somehow to open that black box and check elements inside.
If any remarks i'll post here than.
This device,although it is a bit "obsolete", is still very useable...i can tell.
I checked it on my regular test field, where usually checked so many detectors
so far. Results are very good! I am very satisfied with it.
Right now i can not help here with any more than post a few photos....
Regards

P.S.
Any tip how to open box without damaging components and pcb inside?

Any tip how to open box without damaging components and pcb inside?

Hi Ivconic . Here is the answer that Alexismex gave to Qiaozhi when open the black box of Mineoro.
"Hey Qiaozhi, I tell you my secret 70% to depotting all the epoxy and polyester, urethane and silicon resin ...USE cold (freeze) and hott temperature (500-600°) alternating , the resin brake gently very quickcly and many times the electronics resist very well (because the temp do not go direct to it, always the resine "brake" 3-4mm above the ic,resistor,inductor, etc...)...it is the essence of the technique, imagine the tools and you have the other 30% of the secret.you can see in the photo the scraped away in flakes and chunks"

I had this detector .it is really good one.but stolen 3 years ago.
I remember that black box.but not opened it.
take care of it
