Let us know if you find something cheap. I've been looking
for something like this to use on my lawnmower. Already have
a big ole magnet spinning around on the flywheel, just need
something to read it cheaply.

You gave me a thought. My Fluke 117 reads frequency. I wonder if a wrap or two around
the spark plug wire would be enough for it to register?

Currently my meter is at work and I'm waiting for a blade adaptor since mine is cracked or
I'd be telling you how it worked out.

well, for whomever originally wanted some thing - it just dawned on me that
I have the "speedometer" pulled off of an exercise bicycle that is exactly
what you want - still works

if you want it ping me off the list (get my email form my web page,
www.wbnoble.com )

oh, and I wouldn't put the fluke's input near the HT plug wire - that's a
good way to turn your fluke into a brick

I was thinking of using a shunt resistor.

My Fluke can read frequency too, but at ~$300 it ain't the
cheapest way to go. Would probably work okay for testing and
such though. Just hook on to the alternator output and
divide the measurement appropriately.

I want something cheap to display the RPM while mowing. I've
got horsepower plus, only need to run it fast enough to get
a decent cut. Even at maybe 3/4 throttle I can't hear the
motor hesitate a bit in the deepest grass going full out. If
I could see the RPM it would be a lot easier to duplicate
the sweet spot where it cuts good enough for me.

For ~$40 you can get one of these:

Which is about the easiest and cheapest solution I've seen.
May eventually get one, was hoping to pay even less though.
Already have an hour meter, really just want the tach.

Google on "tinytach" they make a small tachometer for gasoline or
diesel engines. I have a couple and they work as advertized. I believe
that the gasoline model is $39.00
