              Hello everyone, since no one told me and I have not the book to see the details, I did the TX coil 10 cm in diameter, I do not know if it's okay, I connected the TX and the totem always sounds a continuous beep.

                Although the TOTeM project is relatively simple for someone experienced in electronics, it is complex enough that you cannot simply guess the number of turns, or hope to fiddle about with it until it works.

                The book is available direct from the authors here ->
                Inside the METAL DETECTOR - Published September 2012
                or from the UK eBay website (search for "Inside the METAL DETECTOR"),
                or from the UK Amazon website.
                You can also order the book through various bookshops (via Neilson Books).

                  hello ........tx and rx

                  I will buy the book for sure, but what it costs you tell me the diameter of the tx? 100mm? or 10cm? I finished the totem should I do just the coils, if I send to get the book when I get to spend two months.
                  someone help me to know the diameter of the tx and rx? tanks

                    The TX coil is 8cm in diameter.

                      Qiaozhi hello, I thank you with great pleasure, I made the totem, but I do not work, as soon as I connect the tx will lower the volume and heats up the tx and I can not find the point zero.tanks

                        You will find it extremely difficult to build ITMD without reading the whole of Chapter 14. Simply looking at the schematic, or using someone else's PCB layout and parts list, will not give you enough information.

                          How long does the book "Inside The Metal Detector" now exists and how many built the TOTEM?

                          ca. 1,5 years , 15 persons !?

                          So where are meanwhile the interesting and hopefully true results of those who built it?

                          And where would positive find-results of those reached them already with this device leads us?

                          If the TOTEM is close to the Alonso Circuit the personal subjective seen pro and contra results
                          should be pretty similar and obvious compared with Mineoro etc. users.
