RE: LM3914???

[Frederic Breitwieser <Frederic@xephic.dynip.com>]

The only drawback to this module is that it has an on-chip 10/1 divider, so
it reads 1.2V to 12V in... rather than 0-1V.  Good idea though.

www.digikey.com has the LM3914N for a little over a buck in single quantity
and the all the parts can be purchased for about 10 bucks minus the box and
perf board.

I made this and it works well, except I made eight on one board, using eight
10-segment bar graph LEDs, allowing me/us to monitor Air/Fuel on each
cylinder of an engine on a dyno.

Even better; Jameco sells a complete unit that has the LED segments and
chip
all on one board - even less soldering! Costs $6.95 in their catalog.
Might
be a bit more expensive than just buying the chip and a 10-segment LED
display, but it's a lot easier than trying to fab a board and hopefully
not
fry the LED's or 3914.

http://www.jameco.com is their website.
