No problem, don't bother. Whoever asked me, I do not trust them.

Hello guys,

I just wonder to where this jumper (in red circle) connected?

Hello guys,

I just wonder to where this jumper (in red circle) connected?

On the schematic it shows only one connection from U3 pin 1 to LED1. I think this may have been left over from tests made during development of TOTeM, and it's no longer required.

Is it OK to replace CA3240 with LM1458?

The pinout is identical, and there's no special reason for using a CA3240.
So the answer is "yes".

Hello
Dear All.

Finally, I was able to create the PD-Pistol correctly. In following, there are two videos from my PD, which my clients sent me from their successes.

I see that you've managed eventually to register ok, so welcome to the forum.
At first I thought you might be a spammer who was trying to register with multiple fake email addresses, but it appears that there was some other problem.

Well done on duplicating the TOTeM project. I notice that you have modified the design somewhat, and included a DVM on the front panel. Is this something you would like to share with the forum, since this is an open-source project?

Thanks Qiaozhi.
My mail was not fake, your activation link comes with a little delay.
I called my Pd as PD-GoldZeus. It not only has DVM, but also includes some internal changes.

Hello
Dear All
Yesterday, i received a video from one of my clients.
In the video, there is an ancient hill and he is able to hunt a valuable point (buried gold).
You can see the video in https://youtu.be/UjlO-dL98BQ.

This circuit is a little messy, and who can turn it into a complete circuit diagram?
