$1 counter ?

[Jerry]

I was in the local dollor store (wife getting chritmas wrap and such) I got some sandpapper, glue, 3 big calculators and I couldn't resist this littel step counter.

You hook it to your belt and it counts steps up to 99,999. It apears to have a small pendulum that swings up and down. Not sure what type of scensore picks up thisd movement?

I was thinking maybe the could be modifide to become a tack or something? Seems to work well and even comes with a AG13 button cell battery rated to opperate this thing 24 months.

OH well it was only a buk?

Norm re-did some $1 calculators to counters.

Works quite well.

Problem was they couldn't count fast enough for some things.

Norm would be all over this one, but his 'puter busted.

Mount it on your coil winder to count turns.

Jerry,

       Right on Jerry...here it is:

  Only thing they can't count very fast maybe not

over 200 rpm. but would be okay for a manual coil

winder counter unless you're really fast!

  Then for a rpm counter like on a mill you can use:

disadvantage with this one, it shuts off after

5-10 minutes and you lose the data.

Not quite right the problem with the calculator..

...wasn't !!

 The mechanical contact would float aat about 100 rpm I needed....(still do...) some

magnetic reed switches or how to use the optical counters in a $1 mouse....Yes you can even buy

$1 mouse at Dollar Tree.
