MD SCORPION by CHIPSETT

[Artyom]

Hello members of the forum, I bring to your attention a metal detector circuit, assembled by me several years ago from the most interesting nodes of various devices. The result is a stable, deep and fast detector. You can also connect to it a sensor from an ACE 250 with loop capacitors, shown in the green rectangle, I use 6.5x9 as a sniper rifle. Collect and use. Regards, CHIPSETT

Hi
Nice job, must have been a lot of work to do it. Do you also have a lay file? Im interested in this schematic, maybe it works also with 950 BlueMax coil.

Hi Yes, there was a lot of work. Of course I have all the files. I gave the main thing, do the rest yourself, otherwise life will be boring and people will stop thinking. No offense....

Time is the key .

Is there any video related to this detector? To get some impressions of its work? How does threshold tone sounds - rough or smooth... Any air tests or in the ground...

You are a little mistaken in the forum --- you need to go to Tik tok

The .lay file creation is in progress...

This schematic is the same Admiral metal detector.

This is normal. Change a few components, call it a different name and praise)))

Thank you for working with it, Im interested in your work.

2/3 is already placed and traced. I decided all resistors to be SMD 1206 (smaller pcb dimensions, less wholes to be drilled). All other details are DIP version.

In the video, the depth is 40 cm, a copper coin with a diameter of 4 cm, the soil is black earth. There are some false positives because the unit of the device in your pocket and next to the phone, creates interference.
