Pistol Detector - TOTeM (Complete Details)

[Qiaozhi]

Although Edition 1 of Inside the METAL DETECTOR (ITMD) has been completely sold out for several months, we still receive requests directly from people who are interested in Chapter 14 (The Pistol Detector).

Therefore, as an early end-of-year present from the administrators of this forum (and authors of Inside the METAL DETECTOR) we hereby release complete details of the TOTeM project from Edition 1.

Enjoy!

Thanks for posting. Not that I'd buy one but curious why you don't sell the completed boards, etc. as a partial kit? That way it would be easy enough to modify to get the thing to work without having to spend how many hours for us "slow" types.

The last 3 weeks i am searching for information to build your project.
That was ... "the right timming".

Thank you so much Mr Qiaozhi.

Look at this thread ->

where Goldmaxx did an excellent job of following the instructions. There are also several videos of TOTeM in operation.

Snesko made a PCB for TOTeM, but he posted the files on an off-site server, and these files have since been removed.

I will leave the design of a PCB to members of the LRL Forum. This project is now in the public domain, and hence it's up to you what you do with it.

Thanks.

Just so you know. I am not agreeing with some of your "conclusions". I'll leave it at that. Of course most say I am unconventional.

Q,
I did enjoy reading about the ferrite rod, etc. I've said it before there is something about the ferrite rod I swear it pulls the signal in--makes a pathway for the signal to travel on. In the past I have used the tin can and string telephone analogy.

Something like what happens with the solar wind at times,what they call a magnetic superhighway. I'm not saying there are particles, just the magnetics. So, yeah, I don't know what i am talking about, but there is something. Like they say, when you get outside of the crowd you can see from a different viewpoint. For sure, I have the outside part down real good.

Curious about the ferrite rod iron rejection. I have not experienced this with my contraption, just like to know about the cause of this problem. Someone on the forum asked me about this so I offered to help them.
