Simple homemade pulse detector

[Ruben2000]

Hi friends!
What do you think of this detector? I found it on YouTube and it seems to be quite powerful. The person showing this detector used it with a tin-plated transistor and a voltage of 16 volts.
What do you think, friends? Is this detector good for working in real-world conditions?
Here in the video, they give you everything you need to build it.
I look forward to your opinions!

It's a very basic design and appears to give decent results, but I can't imagine it will ever beat a sampling design.

this is 'PIRAT'. russian project BTW. simplest. i took a circuit in your link in your video. you can find up all info in GEOTECH, without problem.

Pirat - stands for: PI - means pulse metal detector, and RAT - the author's website: "radioscot" .

Here I share the schematic of the detector from the video. I drew it in EasyEda. I should clarify that the video is not mine.

Thank you very much, KT315, for the information.
I've seen several pages about building a pirate metal detector, but this is the first time I've seen it on video and the good range it has. I hope it works well in the field.

Is R13 correct?

[Ruben2000]

Is R13 correct?

Hi Carl!
The drawing is based on the PCB shown in the video. Between pins 3 and 4 of the 4558 is R13 (68K). What I see is that the detector runs on a 16-volt power supply, and instead of the IRF730, they used 2SD380 (power transistors).

Here is the latest modification of the device.

I don't know where you look for those kind of "Pirat" videos. But on Youtube are countless videos about the Prirate detector and how it performs.

Hello, Im planing to built Vintik PI V2. Did somebody finished it allready? Im planing also replace the parts, but Im not so good in parts, that is why Im using AI and it offered me to replace
TL074CN, by OP4140
and also other parts
all NE555 by TLC555CP - which has lower consumption
T1 IRF740 by IRL3705N - has lower Rds than IRF740 (higher magnetic pole, which will increase depth) and has max voltage 55V (secure in higher induction point, which can be higher than 16V)
T2 2N3904 by BC546B - need to check if the Ic max will not be higher than 100mA
T3 BF245 more concrete BF245B
T4 2N3906 by BC556B - need to check if the Ic max will not be higher than 100mA
VD1 1N4148 by MUR460 - to secure overvoltage from coil
VD3 1N4001 by 1N5404 - faster
VS1 1N4728A (5V) by LM431ACZ (5v)- need to check if the Ic max will not be higher than 100mA


All the changes and inforamtions are from AI (chatgpt and gemini). There are more changes with rezistors, capacitors fro IC2 and 555. I will get all the info together and post it lately.

Hi,

better forget about chatgpt and gemini to "design" your circuit because all is nosens what they told you. Better study the subject the traditional way and read a book or visit online tutorials on electronics.

Correct. For example, the IRL3705N is completely wrong for a PI design. ChatGPT isn't as smart as it thinks.

Correct. For example, the IRL3705N is completely wrong for a PI design. ChatGPT isn't as smart as it thinks.

What they're calling AI at the moment is actually a very fast search engine which presents the results with a human-like response, albeit with a bit of adaptive learning thrown in.
There is no so-called "intelligence" there.
We are still in the reactive machines and limited memory phases. Theory of mind systems are only theoretical, and self-aware consciousness is still pie in the sky.

I've asked both Grok and ChatGPT several questions, the answers to which were just plain wrong.

[Carl-NC]

Yeah, I've also gotten a lot of wrong answers from ChatGPT. The funniest was when I once asked it a question, it gave me a wrong answer, and when I pressed it on the details it completely changed to a different answer as if it had never suggested a wrong answer in the first place. That's when I knew engineers were behind it all. ChatGPT is also big on flattery ("That's very observant of you..."). There is a hilarious episode of South Park that parodies this aspect.
