[email protected] mentioned... [snip]Can you write a technical description of how that circuit works?
Pretty sad "design".
Well, yeah - hey it's simple. The URL for the whole project,
including a technical explanation of circuit, is at

If Electronic Design isn't the authority, then who else can you trust?

Electronic Design an authority? ROTFLMAO!
Well, that's why I included the smiley.
Particularly got a kick out of "There's a limitation..." ;-)
That's nothing more than an *inaccurate* hand-waving.
The purpose of asking for the data-taking was to cause your mind to do
a little correlation and then some further thought ;-)
For instance... what *is* saturation and what determines when a
transistor will come out of saturation?
...Jim Thompson
IIRC, saturation is the point where Ic has reached its maximum value,
and further increases in Ib won't increase Ic. THe .7 or so V between
emitter and base (assuming an NPN) is a half volt or more greater than
the < .2V collector to emitter, so the collector-base junction is on
the verge of being forward biased. So more and more collector current
'leaks' into the base.
When the collector-base junction is no longer forward biased, then the
transistor is no longer in saturation.
