Not true. Encouraging people to use 555's should be a misdemeanour,
but there are (rare) situations where the the 555 could be the right
solution. I've not run into one in thirty years of design work, but I
suppose there must be a few applications where it is still the right
choice.
I tried to use one once, but the electrical environment was very harsh;
all my circuit did was eat 555s.
So, I started over and used an ordinary astable with some robust
transistors, and it got the job done. Unfortunately, the project
died due to poor mismanagement. )-;
Cheers!

I'm just about to try syncing 3 little smps together. Of course the
555 was the first thing that came into my head as a master clock, say
80K, what would you suggest?
I'm certainly not going to use a PIC
The 74121 and 74221 both produce more stable delays than the 555, with
less jitter.
I'd be more likely to stick a crystal oscillator onto a PLD.
Thanks Bill, I'd actually forgotten about 74121s etc. but I think an
crystal + PLD may be a bit overkill,

adjustment came a year or two after that).
Dare I ask how it's possible to score over 100% ? It's not by any change an
attempt to massage the average figure is it ?
Talking of which the average figure someone posted is equivalent to 56% which is
pretty damn lame.

SAT scores have no direct relation to % correct. |

But let's hope the relationship is at least monotonic.

Like I said, mean people suck.
I agree. What sort of sick, twisted scum sucking bastards lie to thousands
of people so they can steal from them and live a life of luxury while their
'believers' live in misery? Apart from Republicans that is?

In the "Who Really Cares" book, there's a pair of USA maps. One shows
the states where people are most generous, in terms of charity, blood
donations, volunteerism, that sort of thing. The other map is the
states that voted for Kerry. They are almost exact complements.

Cripes!
You expect mismanagement as standard. Having poor mismanagement must really
suck.
What sort of Mismanagers are schools turning out these days?

You persist in seeing things in the most simple minded terms. What does that
tell us about you? |

That I believe in causality?
That the most self-declared-liberal people I've known were also the
meanest to real people around them?
OK, what's your, more nuanced, explanation for the mappings?

Ah, aren't you confusing liberal with libertarian? I think there is a
difference. |

That neither right nor left wing voters are a single block of identical
persons. What happened to the 'wide tent' the right keeps proclaiming?
What makes you think the methodology used in the survey accurately describes
the claimed result?
Practical experience would suggest that those who do the bulk of the work in
helping the afflicted are as different from the Hollywood elite you hate as
the conservatives of the mid west are from the Cheneys and Rumsfelds of the
world. |

Actually, there is no claimed result; just two maps. But I am pretty
good at pattern matching, as most engineers are.

Hate? Have I ever expressed hate for anyone?
You are projecting. I don't even hate you.

I think when he says "self-declared-liberal" he's excluding Libertarians
by default. A "self-declared-liberal" is just a Socialist in a Democrat
suit, just like a "neoconservative" is a Nazi in a Republican suit.
Find out how libertarian you are:

Libertarians seem to have the core political belief "I want to be left
alone." That's not as agressive as a classic angry liberal, but it's
not real supportive, either.

By degrees. Traditional liberals are libertarians too.
