Munch away.
At one point, I mentioned a header. This http://www.digikey.com/product-detail/en/aries-electronics/16-600-10/A103-ND/4260 is what I was talking about.
The idea would be:
1. to use these for the input/output of the comparitor. For example you could try out different filter combinations and different valued resistors without wasting your main board. They are re-useable to a point, but the hand made breadboard even less so. You can do things to help out in that area, by using 0.042 hole push in pins by Vector.
With your comparitor on a DIP socket, you could swap out an inverting comparitor if you liked.
These headers would be socketed.
Doing stuff on the output, maybe you could use an LED for trial #1 and something else for trial #2. ANother part, that could be useful is this one: http://www.clare.com/home/pdfs.nsf/0/B850B566672E5B828825806F004CB226/$file/CPC2907B.pdf or similar.
You could have one section operate the LED with the cr2032 battery and another use an entirely different power supply.
But, i still like playing with the input/filter circuit with a LED and then graduate.
Search out buzzers and see if they are loud enough at 3V, 9V, 12V whatever.
Here: http://www.mallory-sonalert.com/AVBySeries.aspx there are buzzers that may not even be suitable, but you can listen to their sounds etc, but probably won't be able to tell how loud they are. I put a sonalert on my "alarm clock" which is actually a timer. In order to guarantee that I wake-up, I have to turn the clock around so the sounder is facing me. I did use the variable volume disc.
For like fun and giggles, you could use a wall wart for the alarm buzzer, but make make the probes use a battery for safety reasons. These are just possibilities. Thrown out as an idea, not advocated.
