Brown on lightbulb changing:
Roman B. knows where you can get light bulbs changed for
free and they also throw in a new socket.

Scott D. knows how to do the change process in 3 less steps than anyone
else but it takes more time. He also knows a way that takes 1 more
step, but cuts the total time in half.

Bob Blick will also show that light bulbs are most useful when in
motion, and has a contraption that can detect failure and change said
bulbs automatically (of course whilst still in motion).

Finally, a few will point out that the bulb should not be forcibly changed,
instead it should be motivated to change by providing an environment wherein the bulb can change itself.

Students/Newbies DEMAND help on changing and the subsequent blinking their light bulb.
Wouter refers them to examples on his web site and mentions his light bulb programmer.
He even sells light bulbs in small quantities!

Tweed, Lathrop:
Most fish tank pumps pump air, not water.

But water pumps are out there. I know because I bought the pump for my
temperature controlled water bath at a pet shop and it was sold as a
"fish tank pump". Of course that was in 1980, so maybe the fish have developed
better technology by now.

Probably the People's Democratic Republic of Elbonia. They only have one
PIC and it's a 16F84A, replacing the older 16F84 that was destroyed by
angry mobs in the popular uprising of 1998.

Subject: Re: [PIC] PICLIST admin stuff

I propose to consider new [ASP/SQL] tag on this list.

Actually PIC based devices could serve as light web clients within
ASP.NET/MS SQL applications. This kicks off huge market. Hope MCHP
people will understand it not too late.

For example, your know, here in "Texas" sized Inner Mongolia we would
like to equip every camel with cheap Internet-over-GPRS enabled
PIC-based mobile to report to California based web server about the
current condition of the camel and its load.

The "data logger" software on the server would report in real time
about camel status, and would predict camel possible failure, so a
herdsman would receive warning SMS and could care of the situation in
timely manner.

We have a good number of camels roaming around the desert.
So the project seems to be quite big.

Some good/gold level PIC professionals are on the list to consult
with. And for ASP.NET/MS SQL part of the project we'd like to have
consultants on the list too to keep the development consistent.

So, again, why not new [ASP/SQL] tag on this list.

Gokhan SEVER responded to me as follows:

"P is defined as 10*log10(p / 1mW) with a unit of dBm. And here m means
decibels relative to a power of one milliwat (1 mW). Therefore we don't
need
to use an extra milliwatt in our final calculation. "

I don't agree with this. For instance, let's say I take the following
four sentences:

The current is 1 amp.
The current is 10 amps.
The current is 100 amps.
The current is 1000 amps.

Now let's say I convert them to milliamps, giving:

The current is 1000 milliamps.
The current is 10000 milliamps.
The current is 100000 milliamps.
The current is 1000000 milliamps.

Then I convert to bels:

The current is 3 bel milliamps.
The current is 4 bel milliamps.
The current is 5 bel milliamps.
The current is 6 bel milliamps.

Using "tenths of a bel" instead of bels, I get:

The current is 30 dB milliamps.
The current is 40 dB milliamps.
The current is 50 dB milliamps.
The current is 60 dB milliamps.

So the unit I'm left with is "decibel milliamps", or in shorthand: "db
mA". Note the presence of "A" to indicate amps.

Why one earth do people write "decibel milliwatts" as "dbm", i.e.
without the W to indicate watts? I remember when I was back in college,
we used to get docked marks if we left the units out; for instance if
you gave an answer as "5" instead of "5 amps", you'd probably only get
90% instead of 100%. So why is it OK to leave out the "watt" in "dBm"???
Where did this practise start, and why do so many people perpetuate it?

I can convert whatever I want to decibels. (Why wouldn't be able to?)

I have 100 dogs = I have 20 decibel dogs
I have 1 million dollars = I have 60 decibel dollars
The universe is 6 billion years old = The universe is 98 decibel years old
The diameter of Jupiter is 142,984,000 m = The diameter of Jupiter is 82

That's wrong several ways. First, there is no ratio here. 20 dogs compared
to what? You haven't specified what the 0 dB reference is. Second, you are
implicitly saying that the number of dogs is proportional to power. That is
rediculous, certainly without context. How do you know they're not related
to the power squared like volts are, or some other relationship?

To stretch things and make this example correct you could use dB to compare
the motive power of sleds. You could rate a 15 dog sled team some dB above
or below a particular snow mobile, for example. But you couldn't give your
sled team a absolute dB rating without specifying the 0 dB reference, like 1
Watt, 1 Horsepower, the equivalent of 10 standard sled dogs, etc.

A new unit, the Hb (handbag), is being promoted by Prada and Gucci.
Roughly equivalent to a hecto-chihuahua, dBHb would be a useful
measurement of vacuousness

But there's also a lot of Shitzu around of course
