There are several factors.

1. Basic rate structure as approved by some regulatory body..
This varies by location, depending on the type of power generation
equipment and the distribution area. Usually with differing rates for
residential versus commercial versus industrial use.

2. Usage rate structure.
There are different usage "bands", depending on the average
daily/monthly power usage (usually only affects commercial/industrial users).
Think of it as wholesale pricing. This pricing is a two-edged sword, as
exceeding the contracted-for usage level can bring high penalties. This is one
way the power companies try to manage peak usage.
I worked in a large office building in Atlanta, GA, that ran the emergency
diesel generators on the hottest summer days to provide enough power to avoid
exceeding the contracted-for daily power requirements. The penalty rates must
be high, because diesel generators don't provide cheap electricity.
Our campus was on one of those plans. If we exceeded a certain
threshold on a hot day, we got socked with a huge charge. Tens of
thousands for just a few days.

Just a curiosity and a little personal experience. The curiosity is during the
Calif. energy crisis some high energy users (e.g. alumimum manufacturing) had
long term contracts for low cost energy and found it cheaper to shut down and
sell their rights to electrictricty on the open market.

I have an all electric apartment with a time of day meter that has probably
saved me many thousands over the years. It is not very hard, to cope with: I
have the fridge on a timer (cycles on and off during the day - on all night),
shower off-peak, watch the A/C during the day in the summer and that is pretty
much it.

The fan that Lambda used was anything but cheaply constructed. It
had steel cased ball bearings, and a fan good signal line. It wasn't
the fan's fault that lambda put the fans at the end of the heat sinks
and sucked the hot air through the fan. It basically cooked the grease
to death.


Chassis are supposed to be positive pressure. That would be fans
pushing air in, not sucking already heated air out.

Poor design.
So the moral to the story would be......
Buy high end fans if you want reliability like the Lamda supplies....I
remember finding those supplies still working on 25+ year old
equipment that was scrapped....
But anyway...you buy cheap ones...you best have a good preventative
maintenance crew to baby sit them from month to month......

You need to see the bigger picture to understand why the catastrophe
happens. Take a flood plain, build on it, put embankments on the river
in the centre of town and Bingo! a disaster waiting to happen.

This ain't rocket science.


This wasn't a flood plain, nor a river. This was a deadwood issue
where greenies, thru their political connections, wouldn't allow
anyone to go into the forest and clear it out.

That is going to change!

Hi,

I am working on some project that works like the Jeopardy Game. What happens
is, there are three teams, with buttons infront of them, and on each team's
desk is a light bulb.

After asking the question, the first one to press the button gets the ligth
go on, on their table, while the rest of the team's buttons are disables,
hence their ligth bulbs dont go on even if they press their button(as ong as
one light is on.. the rest are disabled).

Anyone who can give me an idea of how to do this? I know how to work if it
were only two teams, but what do i use (if realys, any specific one? ) that
would help me resolve this issue?

Thank you for the help in advance,

I used a PIC. This allowed some additional features such as a start
button that the questioner had to press before answers were accepted. Or
is that answerer and questions for jeopardy?

I also added an anti-cheat feature that locked out buttons that were
down before the start was pressed, and a timeout that buzzed if no one
pressed a button in 10 or 15 sec (selectable). Another advantage of a
micro is that you can make some changes in the operation after a few
people use it - some students can be particularly creative.

Heavy duty switches and lights (it was for school use) cost more than
the electronics.
 
Just nitpicking. The PIC would have to poll the inputs, then in a
close call
The next 1 to be polled would win in spite of the previous 1 to be
polled being first.

Why? You could support up to 8 players completely
synchronously with a conventional 8-bit parallel port.

Besides, even if they were polled, you are talking
about a few milliseconds, imperceptable by humans.

Actually all the switches are read at once. At 4MHz the poll time is so
short nobody will notice if there was a tie, but in fact the lower
number switches have an advantage in the case of a tie. I figured it was
so unlikely I didn't bother to randomize in case of a tie.

Imperceptible by humans (with their inbuilt sensors) perhaps, but a
fair number of sporting events are won and lost by such tiny margins -

Certainly! But that is several orders of magnitude beyond

Any Windows 98 or higher though. You can get simple USB I/O adaptors
that use FTDI or Cypress chips. If just serial any micro can do. If
you need USB, you could use the micro as if you did use serial , but
use a USB RS 232 adaptor.

I would like to know how it happened, I was reading the newsgroup last night
and needed to send an email. I clicked new email (which is actually new post
in OE when you are reading newsgroups) and I sent the email. I noticed
straight away what I had done and went to the outbox and deleted the one to
the newsgroup, I checked and it was in deleted items and didn't appear in my
sent items so I thought I had stopped it. This morning it appeared in my
sent items as having gone at 8:40 am. How can it do that and how do I cancel
a message before I download it off the newsgroup, it isn't an option until
it actually appears as posted. I am seriously sick about putting that in the
public domain.

Excuse me now while I go cry in my beer.:(
