So when's the installation date, Tom?

:-)

Just need to tie in the infrared and give it a thorough checkout.
Should be able to send it up before next Friday!


What, you're not coming for a weekend in the Memphis Belle suite?

:-)

Much as I would like to come up, my schedule won't let me for at least
a few weeks. Waiting on me would cause needless delay in your
(and the world's) enjoyment of the MRALS system installation 8-)
Maybe I can get a "rain check" for the stay?
I did test 3 leds available from Radio Shack. Two blue ones
and a white one. The white one looked best due to its 90 degree
viewing angle, and the the higher priced of the two blue ones
was next. The blue one only has a 30 degree viewing angle, however.
That means only 15 degress on each side of center, 45 each side
for the white one. With these high intensity leds, the systems
will look pretty spiffy, if I do say so myself 8-)

Geez, Tom, this is sounding better all the time!

I'm really looking forward to it -- and you can "use" your "Memphis Belle"
rain-check anytime, if you can't make it up for the "grand install!"

The previous tennant of my office left behind a passive infrared
detector from his security system. I probably can integrate that into
the system as well, and adding a pot to set "turn off delay" will
give you an "auto start with time delayed off" function.


The detectors I've seen used in security systems have been low voltage units. If
you need 110v, the heat/motion detectors used for outdoor lights work well and
can be purchased separately from the lights. These usually have primitive adjustable
timers. Many of them also have photocells to keep them from operating during the
day, so, if you go this route, disable that.

Great discoveries are not announced with "Eureka!". What's usually said is
"Hummmmm... That's interesting...."


How wierd! George's post just now showed up several days late! I'm not
sure I even want to know how that happens. 8-)
Anyhoo, the passive infrared works great. Runs off the 12 volt "system"
supply, and has relay contacts that I tied into a "port" pin on the CPU.
A pot gives a 0-256 second off-delay adjustment. The MRALS system
controller has passed hardware and software testing, and just needs
to be mounted in a small box and shipped!

And Jay, I do hope to "cash in" that rain check soon! 8-)

I just switched to Verizon DSL from Comcast. Verizon has their own news server
(Comcast sub-contracts that). Being a former part of the old Bell Telephone
System, Verizon is real big on doing things their own way. I suspect their ideas
about connecting to external networks are, shall we say, unique.

Saw it here no problem at somewhere around the correct time.

Well, I'm not an expert on the net, but as I understand it, a post is relayed from
the server that accepts it to one or more other servers in the net, who relay the
data on as well as storing it for their users. The time between my posting the info
and someone else having it available is directly proportional to the number of links
the post has to go through before reaching the reader. In addition, if there is a
"critical" node in the path between the two, and that server is down at the time,
the post may be lost or some time may elapse before it arrives over a more roundabout
path. Users on other servers may see the post immediately because the server which
is down is not a critical node in the path to their server.

One way to avoid this is for each server to send postings which it receives to
several other servers, rather than just one. This is, however, somewhat of a foreign
concept in telephony, so I theorized that Verizon may not be doing this in the best
manner. Then again, they may. In any case, that post was made in the first day or
so that I began using the Verizon account, and that may be the reason behind the
delay.

Of course, if Tom's server was down at the time my post would have reached it,
that would certainly count as a "critical node".

Ah. Funny that it gets to a Dutch or Swedish server, wherever this
is, quicker! :-)

It is amazing how we have come to take this "world-wide" web for granted,
no?

I push this here button, and Paul is reading it in Great Britain --
instantly! Who'd ever have believed it?
