It's clear to me that if the motor load is resistive and draws 6 amperes
from 115VRMS mains, then the power delivered to a nonreactive mechanical
load cannot be greater than:
P = IE = 6A * 115V = 690 watts.
As a matter of fact, (so far) the three basic laws of thermodynamics
are:
1. You can't win.
2. You can't break even
3. You can't get out of the game
So, for 690 watts taken from a source, what will be delivered to the
eventual load will depend on the price exacted by the delivery system.

True, but still utter nonsense since we draw power from a voltage source
which _is_ fixed at 120V.
That means that no matter how much power we ask the source to deliver,
it will deliver it into a load which is designed to drop 120V at its
required power
---
Sure, if the 12VDC source can supply 50 amperes into the load without
sagging, but so what?

I think what's been confirmed is that you're an idiot and, consequently,
that your opinions are irrelevant.

This should be better when there is no moon, further allowing exposure increase.
It takes a few pictures for teh auto exposure to stabilize
Had to scale the images down to 1400 x 1050 pixels so the movie would

Not bad for that cheapo camera, it is all in the software
The sensor is very good, very little noise, but some compression artefacts.
For the Linux users:
This is how the avi was made, from the camera jpegs
For each jpg, from a script:
convert -resize 1920x1050 nnn.jpg nnn.jpg
This processes 1375.jpg to 1417.jpg:

Crickey, what is it made of?
Those Vishay Bulk Metal resistors:
http://www.vishay.com/resistors-discrete/metal-foil/
are made of a proprietary variant of 75Ni-20Cr-3Al, which is roughly
an order of magnitude better than Shunt Manganin, and is the lowest
resistance tempco material known in the vicinity of room temperature.
One commercially available variant is known as Evanohm IIRC, available
as foil and wire in case you want to make your own resistors
When comparing tempcos of different materials it is important also to
compare the specified temperature range or better yet look at the
resistance vs temp curve.
Low resistance TC metal alloys get their low TC the same way Invar
gets its low thermal expansion. Invar, at one specific temperature,
exactly cancels thermal expansion with a gradual phase change to a
lower volume phase. Low TC resistance alloys like Manganin and NiCrAl
exactly cancel tempco at one specific temperature with a gradual phase
change to a lower resistance phase. The further you get from the
temperature which is exactly compensated the worse the tempco in
either case. Specify TC very close to the compensated temp and you
can make it arbitrarily low

Glen
Thanks. I appreciate it much better with the explanation of how it
works.
How about OpAmp offset voltage? That'll do you in royally, unless you
have an auto-zero periodically.

I use reverse osmosis myself, I don't bother with "geniune DI water" (what

fact, I don't buy the theory that plain drinking water isn't fine.
It isn't like you're running thousands of gallons through a battery and
the contiminents will be left behind and build up. In the lifetime of a car
battery, less than two gallons of water will be added.
You really have tons of arsenic in your drinking water, enough to

Not true. Humans can tolerate quite high levels of dissolved salts like
magnesium, calcium and sodium chlorides in drinking water.
Lead acid batteries do not like chloride contamination.
Much more likely to be chloride contamination that does the damage.
Your loss. Lead acid batteries will last longer if you look after them.
That isn't the point. It only takes a small amount of chloride impurity
to cause trouble. There is good reason why lead acid batteries use

You insist that power is in AMP and you assume power in car is fixed at 14V. Not always, some are less some are more, big truck uses 24V. So you were wrong.
