Thanks, Joe
I am using the Microchip 18F452 - which is probably
overkill - but its structure makes it easier for me to program without having to
worry about memory banks.

Ed,
What
processor are you using? Nice job.

Geez,
Finn, I was unaware that there was a "protocol" for resistor sizes on PC
boards. Seriously, is there some reason (vibration?) for forcing
resistors all the way to the board or is it just
"esthetics?".

- Nice.
- I assume those resistors are just temporary until you get hold of
smaller ones that can actually rest on the PCB rather than hanging in
their legs? I know it's not flight critical, but still...

system, I have mentioned in the past (seems like I've been working on it
forever). Got the PC board in today and got it mostly populated
with the components. It will sit in a 2 1/4" instrument case with
the LCD extending out past the boundary of the case. I plan on
trying some vacuum molding of thin ABS plastic to form a
attractive front cover.

- The front panel shows the LCD display screen as well as the push
buttons for loading fuel, setting alarms and selecting which screen you
wish to display. The center shaft controls the LCD backlite so it
will be visible either in day or night.

- Hopefully, I have designed and constructed the board properly (my
first microcomputer/controller board) and if so, then the software
(which I have completed) will be loaded and it will be installed
in the aircraft for testing. I certainly plan on having it
installed for Sun & Fun.
