Old and new things used on Birds - Ralph L. Fullenwider - 05-27-2009 03:06
Hi Bill:
From tube logic, to relay logic, to??? and on and on. Today we have more
computing power in a hand held Blackberry than there was to put our men on
the moon and bring them hope safely.
Odd at how some of yesterday's technology is still used in RV's and Birds
today. The "ammonia" gravity fed refrigerators is one. The electronics of
today is used to control, change, and re fire the system but the system is
still old school and works nicely.
We have seen the Birds go from micro switch logic to relay and then further
into the fiber optic, central hubs with satellite hubs going into a digital
central processor. Engines have gone from mechanical control to a DDEC,
DDEC1 and 2 then to computer based units tied into an EPU. Smart
transmissions with on board computers that interface with engine
controllers than can be changed on the fly,,,,, whew, and the test
equipment to trouble shoot all of that has changed and of course the price
of that test unit went out of sight. Remember when we thought setting up a
double pumper or 3 duce carb was a challenge? Now it is trying to find out
how the DD 6 and 8V's incorporate the jake engine break, and that on and
old system.
The list goes on with "smart" cylinders that out put a digital signal for
positioning and stacking two separate units, 20 feet apart and making them
interact as one, every time! Of course drag co efficient's, mechanical
problems interject problems that a computer cannot compute to a point. All
that to make a slide out work. The list goes on and on.
I would guess that many on this Forum know exactly what I am talking about.
My question to my self is; Why so darn complicated just to go camping???
about it all. LOL
Safe travels,

Ralph,
When I was a boy scout, we used shelter halves -- and you always wanted an even number of scouts on a camping trip!! (Or, at least, you didn't want to be the odd one out....)
From experience, I note that there are those who had trouble with the seemingly simple task of buttoning together shelter halves.

The buttoning of shelter 1/2's used to be the most complicated thing
about it all. LOL
