mini pulse

Does anyone have idea how the minipulse "Reject" control works from the circuit point of view (timing?) and practically (iron and foil rejection on a PI detector is my dream)? There is one for sale right now. I have also the GoldScan 2 and it works quite well.

Anatoly, the circuit diagram in your post #18 is not of Minipulse:

Superscan uses 24V batteries.

I agree it is not Minipulse, but his ICs' list are too identical that I have did see at the photos. beside the stabs and power supply is not 24V.
it was only some help to give a vector... I have not the schematic of Minipulse... but I hope to get all schematics of Eric Foster with Gods help as well
thank you Mike!

seems clear this schematic... but power supply is 24 V.

Why? Because I do not want to play in your band "Idea Robbers Brothers".

I highly appreciate porkluvr: just as high - as I appreciate you low. Capish you frula-master?

Ha, ha, ha it's a good WM6. It is better to say "truba"- master.

Sometimes we are joking

And, why is there a need to use 24V? Would not one big-*** 12V battery enough to lug around?

No. It was truck mount metal detector.

Give me a f* break. I hate to be impolite, but that is ridiculous.

There is no way that 24V in and 24V on the ground pin of 78L05 will get you 5V out. That drawing has sub-zero credibility.

detector in pic is only uses one 9v battery

back

hope these ok. . . any one want or need any more pics while ive got it apart again

hope this is ok for i c

thanks for replies. . . . i have some photos of the back of the board . . . if you want me to post them . . .

and again thanks

sent you a PM

Yes but as much clear photos as possible. Present photos are not really clear, IC on photos cannot be identified.

Thank you.
