SBG-PID

Received If the speaker field matches the CD4066's strobe.

Sound is made to no get self-excitement.

Maybe I'll try to redraw the schematic.
I **** on the overtone window

The man who brought SBG-PID here deserves better than this.

I agree.

As I said in the previous post, I respect anyone's effort to make something new or upgrade some existing design.

I also made a mistake comparing with the previous version SBG-PI, didn't mean nothing bad by this, just there was more details about it, and tests.

I was just annoyed by the fact that he did not want to publish a layout, and that's why I started to doubt it.

Comparing someone's schematic drawings to a junkies handiwork falls way outside the boundaries of the Overton window.
Just another example of a thread gone awry because of silliness.
Here a man comes with good schematic circuit of his own work, presenting it for everyone's consideration. Then another person who is hell-bent on folly put large pictures of spiders web and rubbishes man's contribution.
Nobody says anything. He escapes unscathed, now he becomes emboldened to do it again and again without any fear of sanction. The Overton window has now become redefined to accept lower standards of behavioral protocol.
This is the classic definition of the Overton window. The regimes of the past and present know of this concept very well.

Koala, this is not same schematic, this is SBG-PID, not SBG-PI. It is different one.

Returning to topic, after examining the schematic a little more intensely, I noticed that NE7555 audio chopper is VCO circuit? No, it looks like it's configured as monostable, triggered by pin 6 of 4538. I don't think that I've seen this before on other pulse circuits. Would this be to keep everything nice and synchronized? This schematic is all over the place. The schematic must be redrawn. And no layout.
No YouTube video to demonstrate performance? No testing on real ground?
Nothing but unverified schematic with little or no description of parameters, timings etc.
No thanks. This one will need a lot of work.

If that makes you feel better...

The rest were defenestrated through the Overton window
I miss so many people here.

Actually, hardly anyone from the Geotech forum gets thrown out the window. The number that have been banned over the years is less than a handful, and they really had to try hard to get kicked out. The reality is that people come and go all the time. The majority are lurkers, and never post anything. Some are what other forums would call leeches, but many just feel that they don't have anything to contribute.

I do not doubt that the circuit works very well, but it is not presented in such a good way(schematic).

[Andi68]

I can not say anything, I'm just a painter

Attacking/Defending - these words have no purpose in forums like this one or I thought so.
The truth is most interesting topics are the older ones where people used to share valuable info that does really help the hobby.

[dbanner]

Guys I urge you stop the attacks as there are only few people left sharing out their own ideas freely.

Who is main transgressor of personal attacks here on forum, always with political innuendo, calling people idiots and dummies. Who?
When others are defending themselves from such diatribe, then and only then does someone else come along to say cool it.
As if this is some affirmation of why so many people no longer actively participate on forum. Poppycock.

[dbanner]

You have no mind to create this. Better to become a painter ...
