Here's the link to the pictures. I got a number of ideas from this the forum. I initially used a little RC filter for a debounce circuit but found that it was unnecessary with the counter I ended up using. Total cost was under $100. All of the specifics and part sources I could remember are included in the narratives under each picture.
The adjustable fixture for holding the reed switch is essential because a slight adjustment in or out makes the counter unstable. Its just a matter of adjusting the screws until the counter reads properly and doing this isn't quirky at all.
