Re: Congratulations!
Hi Fernando,
Congratulations!
It is the most complex, and probably the best Pi schematic, which I see so far. Of course, need time to analyze it.
Are you make some partial version on raster, or tested analog part with some kind of emulator?
What about Tx CH1 and Tx CH2, you have two controls, but in analog part you are using only one?
About Bip-Beep, Fisher cz5 using a nice simple DA for VCO, which giving different frequency beeps, for different metals. If you interested, let me known.
You also mention possibility of ground balance. Can are you give to us more explanation, or some link, about it.

this is the intent: realize a big project together.
>Are you make....with some kind of emulator?
no, a lot of results depend from many factors like the coil, TX, sampler etc. so you obtain a total variable range of values. (i think!)
>What about Tx CH1 and Tx CH2, you have two controls, but in analog part you are using only one?
to do. The normal timing diagrams will explain the TX usage and the alternate method of sampler. In mono coil the TX will be one for the two channels. Tonight we're analizing better what your're appointing. Yet this is 19:00 in Italy and i must go home!
>About Bip-Beep, Fisher cz5 using a nice simple DA for VCO, which giving different frequency beeps, for different metals. If you interested, let me known.
like a short beep (using the ATMega as tone generator, i have the timer-output pins leaved free for this idea... but a short beep is perceptable? (don't have proved!)Comment

Re: about beep
Maybe is simpler to utilized present VCO with NE555, and with CMOS switch (controlled by IC11) changing resistors (referent voltage) on VCO, with some monostabil (or maybe some simple reset circuit) triggered by level change on IC11.
But, of course, it is the last problem, in comparasion with other problems.
Please, tell me more, about ground balance theoretical idea.

Re: about beep
Wow Cossaro, a REALLY nice design there ;-) It's so good to see you guys coming up with designs that break the mould.
Do you plan to make a PCB for it, as if you do, count me in to buy one off you and build this project.
Also, what about code for the micro? Please contact me via my contact page on my website as I have some qquestions I'd like to ask but don't want ot post my email address on any forums.

Re: about beep
>Do you plan to make a PCB for it
yes, it will be realized in a few week, after a discussion on this forum. I'm collect more opinions to eliminate some problems.
>Also, what about code for the micro?
first we must define the HW and last the SW.
>Please contact me via my contact page on my website as I have some qquestions I'd like to ask but don't want ot post my email address on any forums.
and why not to share the questions and the answers on this forum? There's a lot of space here and I like the people that navigate in it.Comment
