Hi Jim,
with Verizon can't you just buy a data plan and then access any email

And your evidence for this claim is?
The press does mock certain fundamentalist christians, mainly bcause
fundamentalists not only go out of their way to tell other people how
they should live their lives, but also encourage legislation intended
to impose their absurd prejudices on the rest of the population.

Minimum reliable operating voltage appears to be 2.5V and operation
may be more stable and accurate.

I'd go for a circuit with an adjustable undervoltage trip point.
Once power returns,the charging voltage is sensed and the circuit
returns to normal.
I propose one comparator set up with hysteresis, one V reference and a
transistor to drive the relay..
Alternatively a DTL circuit could be made up.
Extra relay contacts can sometimes put to use for circuit function.

Why don't you sell your house and move to a place next to the TV

Or the bare finger.

Low Voltage Cutout

kol...@gmail.com — Thu, 20 Nov 2008 08:05:19 UT

Hi
I have an access control system running off a float charged battery.
If there is a power outage of +-8 Hours, the battery drops to a level
lower than the access-control system can handle, and then it does not
recognise the tags (the readers actually lockup, but the maglocks stay
locked).
I was thinking of putting a 9v zener diode on the battery, running a

Hi Rich,
Someone else has already provided the translation, so that will take
care of some of the wholes in data entry and reading.
Tau is related to the shape of what you call the pyramid, or more
actually to the angle of the taper. This defines the smoothness of
matching across the span of frequencies you entered into the program.

OK brother, you may not be what I accuse you of ...
But darn, the antenna you bought was designed with certain parameters in
mind ... I would seriously doubt you are going to vastly increase
performance with the route(s) you have described here ...

Before you dog on phlatlight, Jim, remember its a MIT project gone
commercial.
Its also one of the few manufacturers I've looked at that can meet its
specs. The inherent 60' beam width makes it useful, or am I the only
one here who has ever found out how frustrating it is to try to make
lambertian collection optics. Yeah, Osram has a roomlight. Try to
