TL12000

I recently built a new TL12000 circuit. Here is the video of it. Unfortunately, I swapped the titles of the two videos. Based on conductivity, it rejects iron better than other pulse-induction metal detetors

Dear Asanka, the video is excellent. I tried this before but couldn't get the discrimination feature to work; after seeing this video, I want to try it again. I would really appreciate it if you could provide the links for the schematic/PCB layout I should use.

Hi ASDF12345,

Here is the TL12000 Diptrace schematic file. Enjoy...

Dear Geomax, thank you very much. I wonder, what is the difference between this one and your other schema?

I wonder if there is a PCB for this?

Hello,

No, there is no PCB for this schematic. I created it solely for study purposes to get a better overview of the many variations circulating online. Also, please note the information in the bottom right corner of the schematic.
If you like, you can design a PCB and publish it here on Geotech.

Have you watched Asanka's videos? The discrimination works really well.
