Cheezy boost gauge

I don't know if anyone is interested, but I cooked up a cheezy boost
gauge with a 30 led display. Nothing special, basically a page out of
the National Semiconductor LM3914 .pdf file. But it does have adjustable
gain, and it fits (just) on a common radio shack pre-plated PC board.
I'll probably put up a pic and a schematic on a web site soon. It does
work with lung pressure and vacuum. BTW, I use a motorola MPX4250 for
the pressure sensing which is a 3 bar absolute unit. Overkill for my
purposes, but it was lying there unused. So when I get a diagram up I'll
post a link if anyone wants it.
