Terminator 3, Terminator Trio

[dbanner]

This is interesting, it's the terminator Trio "M" variation. Notice variable tone discrimination towards end of video. Nice feature.

Problem is that there are so many variations with so many different layouts, still can't find the layout KT posted for "double tone" on the russian forum. Google translator is not so good.
Looks to be a very good detector though.

Here is schematic from russian forum for Terminator Trio "M". Very nice. 4069 cmos chips no problem

dbanner, Your board has very big size,- 82x136 mm !!! It won't be convenient to go with such board.

I have made circuits with a resistor k561,k176 and a sd4000 in amplifier mode. They work unstable. When is no signal increased consumption and they are heating up.

what is no signal? if you leave the input opened you get all kind of noises on input and overloading.

This is not my board. I got this from russian forum. If you have skill and steady hands or can do reflow, then you can try smd version.

Could this audio section be implemented in TGSL. Good idea or not? What do you think guys? It is like variable tone ID.
TC1584/40106 hex schmitt trigger-No problem.

dbanner, now also I do it.

WITHOUT SIGNAL - WHERE THE SEARCH HEAD IS NOT INCLUDED.

i asked recently russian guys to help me to find a schematic that is emulating a work of coil. the signal must be changed
amplitude and phase simultaneously. this device will give us a possibility to check any VLF schematic without coil.

My opinion is not obligated. There is a proverb in Bulgaria : " Everybody is a slave of his own brain "

SCS, I made your mods to this circuit, not working, something wrong? Is this correct?
Does this circuit work?

Very good...BUT, there already exists several SMD layouts on russian forum, why re-invent the wheel
