Built myself a rev counter!!

Though it may not look like you expect! I've been busy with the soldering iron and electronics spare bits box recently, so here it is in all its glory:



It's an amalgamation of various designs available on the internet, and should produce 1 Volt of output per 1000rpm for an 8 cylinder engine (adjustable to get just right). I'll hook it up to a microprocessor and attached Analog-to-Digitial convertor I'm working on:



These guts then sit behind the new console section I've constructed:



Which sits in the dash:



The display will (when I'm finished) display the RPM as a number, e.g. "2000 RPM"

Pics when finished :)

Yeah, the point was you could err . . man sausage Titsy.

That sounds so wrong . .

EDIT - Re. Rev guage - very cool.  I don't understand electronics in the slightest so am easily impressed on that score.
