Metal detector with double tone and reject discriminator

[Sasho Varna Bulgaria]

This is the best variant.

thanks lots, Sasho. recently I did small repair of MD-5012. may be you have the schematic? IMO, MD-5012 has modern design, but poor release of PCB layout. full static mode - ! like to probably old Discovery schematic or similar to. I believe it was copied.

Для этого детектора информации не имею.

za sasho
стига с тия елементарни схеми от миналия век.
покажи нещо с процесори и модерни решения.
тук в тоя форум нивото е много ниско - на гимназисти любители.
даите да направим нещо професионално - дори дикусия.

* all schematic in this forum are completely old and useless for today needs.
please lets make this forum more profesional.
need to install microprocesors inside detector
and discus problems and programing for this purpose.
lets go to high level friends.
soon i will publish here my schematic with two MP. now make sorce code.

please lets make this forum more profesional.

I fully agree. sasho well did learn his Home Work tesoro Clone one
why now we can not learn from our Taiwan friends, sasho? why if we say from china it is always very bad? but I SEE IT HAS GOOD DESIGN, particularly for our aims.

Uncover something better.Ако наистина си правил нещо с процесор ще знаеш че аналоговите работят по_добре.Процесорните се правят по лесно
за парички.Ето защо процесорна схема няма да ви покажа.Вижте из руските сайтове.Те са пълни стакива лошо работещи схеми.Очаквам да видя нещо което ти си конструирал. Може дори и да е от 20 век и да е за гимназисти.

Болгария не спит.Когда в великом Советском Союзе делали искатели на нулевом биением в Болгарии самодельние искатели откривали монету диаметром 25 мм на 25 сантим.
Про китайских детекторах я могу сказать вам что дизайном поиск не производится.Создат saturn-5 американцев не помогли китайцы.Это
сделал фон Браун.

Kt-315 , Is the md-5012 6.99 Khz and 25 cm search coil , detect a small coin to 35 cm ??? Does it work ? Thanks Eugene

[kt315]

I hope do verify these promises when I again will get access to the apparatus but the schematic seems very encouraging.
regards.

Hi KT315. I have the schematic but without components list. I reversed the schematic from the pcb. If you interesting i can post you the schematic at Protel 99SE format.
