Looking for someone who can manufacture & assemble PCB Boards

[mikebg]

KT315,
If you're a designer of metal detectors, what would prefer to do?
Alternatives are:
1. You are designing MD and sell your designs to producers.
2. You are starting production activities which are not required special knowledge, so you are not satisfied.
If you decide to become a producer of printed circuit boards and kits, what should you do further?
1. Wasting your time in the packaging of individual whales and doing marketing through the mail.
2. Maintain a website answering questions continuously rolled around the world.
All this was done.
PD3200 site lasted nearly two years and all the information needed to produce this kit was available to all. Currently, two Bulgarian companies continue to use the kit PD3200 modifications to produce and sell metal detectors. The designers of this project, however, have experience with this kit and decided to make another cheap kit - the DIY GPR.
What will happen to the initiative of Christian? I doubt that he will succeed to do those activities during the whole two years. Besides durability needed two conditions:
1. Existence of a team or group of several people to distribute the work among themselves and
2. Existence of designs and projects outperforming current level not only on price but also on operating parameters. Christian argues that he has such projects. Hopefully this is true!

The problem is not in manifacturing process for cheap and quality metal detecting equipment; the problem is in its
design process. The factory of the world is Asia, and nobody even cheaper labor in Turkey, Russia and Bulgaria do not
can compete with Asian advantages in terms of price at mass production.
Tinkerer, sorry that I will use your nickname, the next sentence did not apply to you.
In Eastern Europe we have enough tinkerers to produce, but we need thinkerers to design metal detectors.
We need designers having enough theoretical knowledge to create new generation metal detectors for demining,
prospecting and treasure hunting. Note that I put humanitarian demining in first place.
To satisfy this vacuum, before more than two years was created a worldwide group of experts for theoretical
knowledge - the (R)EMI group.
The abbreviation (R)EMI means "Reinventing, rename, revision, redesign and rediscovering Electromagnetic
induction ". Most members of (R)EMI group have hobby to design transmitters, receivers and antennas for QRP
amateur radio. Despite amateur radio is dying, it remains most powerful global hobby for knowledge. It has maintained a presence in space since 1961, with the launch of satellite OSCAR 1 (OSCAR is an acronym for Orbiting Satellite Carrying Amateur Radio). Since then,
radio amateurs have launched about 40 satellites with over 20 still in orbit today.
What was done for two years existing (R)EMI group (July Morning 2008 - July Morning 2010)? We have answer of the question "How should metal
detectors work?"
As WM6 noted, the (R)EMI group creates block diagrams. This is true. Let designers try to improuve our block diagrams if they can. We mean this is impossible.
As ex-spokesman of the (R) EMI group, I have the block diagram of the reinvented most sensitive VLF metal detector "GLEANER
project ". I expect the authors permission to post it and I hope this will happen because it is important for humanitarian demining. The original inventor is Vaino Ronka and the principle is described in its patents.
I have good news from Bulgaria:
The designers of the cheap kit "Pulsediscriminator PD3200" are working now on design of another cheap kit "DIY GPR project". This is good for all hobbists, but very bad for radar manufacturers, because it will force them to cut prices.

Hi Mikebg,

I agree with you that the amateur radio community was great in developing radio, but specially great in interchanging innovation and help to newcomers. I used to have a call sign C53EX, amazing that I still remember that.
The radio world has moved out of reach of most amateurs now.
Metal detector electronics is still in reach of amateurs. It is great fun and many innovations can still be made.
If we look at the metal detector patents of the last years, the innovations are ideas that can be implemented by amateurs or hobbyists.
I would even say that there are still an immense amounts of new ideas that could still be tried.

Designing is one thing. Manufacturing is another. 25 years ago a made a few dozen underwater metal detectors for my own use and to sell to a few friends with similar needs.
I could not do this today anymore.
But, if we could find a place that could reliably assemble small series of about 10 detectors at a time, at a cost that would make the final detector affordable,
I am sure that this would make quite a few amateurs (or tinkerers) happy.

All the best

Hi Mikebg,

thanks for the link. Sadly I have not been involved with Ham radio in the last 25 years.
I have known about John's patents and admire him as an inventor, but I had no idea that he is also a Ham operator.
But it proves your point: The search for perfection of the Ham operators also applies to the metal detector designers. With it goes the willingness to share ideas and the willingness to help each other to solve the design problems.

All the best

Hi Tinkerer an all

we need organisation as Ham operators have (Amateur Radio League).

To put our work in legal and protect our rights.

We nead AAL (Amateur Arheologist League).

International and local.

I have noticed that there is some interest in Eastern European countries in developing electronics manufacturing. It appears that there is a high level of skilled people, excellent engineers etc. very motivated to work hard.

With the competition from China and the upcoming competition from India, how do the quality, efficiency, reliability and cost compare?

How does the ease of communication compare? Language problem? Shipping? Customs?

It would be very interesting to get some solid information about these aspects.
There also seems to be a growing market for metal detectors in Eastern Europe as well.
What would be the advantage of producing metal detectors there?

Tinkerer

The area of Eastern Europe is in the former Roman Empire, which is rich in archaeological sites.Relics are located at great depths (about 2000 years old). According to the principle of the "evolution" has created the best constructors metal detectors. Also appearing are those who sell "fog".

You have put the finger on a sore spot there. Archaeological sites. We should make every effort to preserve the history and archaeology of our countries.
Artifacts that are removed from such sites destroy the value of the sites.

As far as metal detecting for ancient lost artifacts, the UK seems to have the bests system. The finder of a site gets a just reward.

Only if the professional archaeologists learn how to work together with the amateurs, there is hope for preserving history.

WM6, I agree, lets'do it. Where do we start?
