[sdiy] quick continuity tester?

[ElmacacoX at aol.com]

Hi all,

I need a continuity buzzer to make my trouble shooting easier.  my dmm 
doesn't have one, and I don't really want to buy a new one just yet.  
I have a little LED roullette wheel kit I built a while ago, that runs off of 
a 9v battery &
it has a little 8ohm speaker, I was thinking that maybe I could make a little 
buzzer to use for now by breaking the power connection and putting in two 
probe wires to test the continuity by placing them over the span I wish to 
test.  
I imagine I don't want to be playing with 9V around the IC's, so maybe a 
resistor based voltage divider to get it to.. what, 3V?

I might be missing what a continuity tester is exactly or how it works, but 
that's  where you guys can straighten me out I hope.

so is this a bad idea?

thanks

Eduardo
