Lynn,
Late last night I checked out Mouser, my favorite electronics outlet. Be
careful though, if you buy too much you will get a New York City phonebook
sized catalog ever three months. They have several 2 volt digital volt
meters. The hitch is that they will need a 5 volt supply to to feed the LCD
display. I have found it almost impossible, though, to navigate their
online catalog.
Try this. In their home page search field, Type in Murata. Then on the
next page there will be a search field titled "Select Manufacturer" - click
on the down arrow and select "Murata Power Solutions". Then click on "Panel
Meters". Here you will find a page that shows filters that will narrow your
search. This is where it gets fun. As you click on the filters, the red
line will give you the number if items still remaining after the filters are
applied.
One other thing, for the 5v supply, do a search on DC to DC converters.
These are small postage stamp sized solid state devices that will convert
the 12 or more volt input to a regulated 5 volt output.
The reason I like this company is that they have almost everything you will
ever need electronically, but they also don't have a minimum order so will
sell to the occasional hobbyist, or the bulk buying manufacturer. They will
also give an inventory supply so you know if it is a stocked item or will be
back ordered.
Hope this helps.
Lowell

Are you wanting digital or analog and with how much resolution?
What is the voltage range you are needing (ie 1.00 to 2.00 vdc or 1.000 to
1.100 etc)
What size display do you want? 3/8 1/2 1 etc
What first comes to mind is an *el cheapo multimeter*
<http://www.harborfreight.com/catalogsearch/result?q=multimeter>set on the 2
VDC range.
(I presume VDC), remove the digital display from the meter and mount it
remotely (your instrument panel), and mount the internal electronics where
there is more room. Don't worry about the other functions, just set it to 2
vdc max and go from there. That automatically selects the number of decimals
to the right of the decimal point.
*Harbor Freight*<http://www.harborfreight.com/catalogsearch/result?q=multimeter>comes
to mind. Buy an el-cheapo meter and crack it open and try it. If you
like what you see, go from there . . . if not keep exploring. You are
looking at a less than $5-$20 investment. I once built a event counter
display out of a $2 calculator to prove a point and solve a problem A
person can throw all sorts of money at something like this. It all depends
on the persons mind set to get the job done, to lean towards the frugal side
or the expensive side. Secondly, is the primary function variable from the
cockpit and you wish to measure and see the results? Said another way, can
you change your timing from the cockpit? If so, what voltage range
correlates with the minimum and maximum timing angles you want to measure?
Also keep this in mind: You can install a couple jacks on your panel or
below where you can plug a meter in and hang the meter somewhere out of the
way. This would be simple if you don't need the information all the time
plus you have your meter intact for other things if needed.
Consider the battery too. Are you going to use internal or external power
for the meter/display? If internal, you will need to be able to change the
battery occasionally plus you will need an on/off power switch or a relay
from your master.
My 2 pennies . . . .

*Try separating the display from the electronics on one of your meters.
possibly you can use a ribbon wire to extend the display from the meter
internals. I would consider using a plug connector between them otherwise
you wind up with the same problem. *

That helps a bunch, Lowell...thanks. I have a Hobbico digital
voltmeter, which I thought about stripping and using, but if I can
find a unit like you describe, that'll be much better. I've got a
local electronics guru who'll be able to help, so maybe I'll get this
thing going. I'm gonna copy this post and take it with me when I see
him tomorrow.
