    hi Seeker!
    is this possible for my TM-808?!

    Hi Ralph sal, I do not know for that type of MD. But it is good idea.If you have some experience in programing software, you can try to create LAPTOP MD. I send you what hardware elements mast consist that MD. If you want to start do this, I will help you in schematic.

    regards

      Hi,

      I made years ago such a metal detector. I was using a good sound card (24 Bit, 96 kHz). It was driven by a 1 W power amplifier and a low noise signal amplifier. I had two signal outputs (signal drive and ground balancing/fine nulling signal).

      I was using this kind of coil:

      It was able to discriminate and cancel all problematic ground conditions.

      Good Luck.

        Some additions:

        Do not start, if you are not familiar with:
        - embedded systems engineering
        - real-time programming and processing
        - digital filters, fourier transformation, digital signal processing
        - etc.

        I made this project using Windows XP on a simple 1.4 GHz Laptop. I was using 1024 sample window, enabling me round about 50-70 measurements per seconds. The output was signalled via display and another sound card (one for metal detector, one for your ears). The signal was processed like BBS technology (from 1 kHz to 48 kHz).
        Indeed there is a big potential to make a good metal detector using only a Laptop, plus good sound card (pcmcia or pci-express), plus very simple hardware (amplifiers), plus state of the art coil.
        I am sure, all the prior art will then sucks.

          Matlab could be just a perfect tool for Laptop detector GUI and analysis..
          Very fast implementation..

            But,

            Azz

            You can show us the schematics and the software, may be you can send me the source code of the program.

            Thanks.

              Thanks.
              I am sorry, but I am very busy on developing an new eddy current sensor (search coil). So the coil software is almost tidy up and improved and I can go further on next days. Some parts of my new graphics interface (better, faster, efficient, etc.) will then be used on the future laptop detector user interface. On laptop detector, the efficiency of software became very important to save battery running time and number of measurements per second.

              The software platform will be only on Windows XP (power save) and not on Vista (what a big sh.it)!

              I can imagine to deliver the hardware part and a frame work source code with no important and intellectual property parts. So every one can start developing his own laptop detector. But this could take me some month.
