So I'm out in the far depths of the E-Quad. Counting every single tooth on every single gear on my clock. I've been working for well over three hours, and I probably have at least another hour to go. Do you have any idea how amazingly boring it is to count gear teeth? And how hard it is to keep track of how many teeth you've counted on one gear once you're past 50?

Arrgh. So bored. Going to pass out and bonk head on table from boredom.

You need one of those clicker counter things they use to take headcounts in large crowds. And how do you know you're not counting around and around the same gear?

Hmm. How did the clockmakers do this, back in the day? Or did they have apprentices to do the counting?

Something tells me this is a job for a digital camera and a computer program. But then, I'm a CS major.

Also, if it's symmetric, can't you just count half or a quarter and multiply?

Asking silly questions because I'm still at work myself... with no hope of leaving anytime soon.

Oops, you missed one. Better start over. :)

Okay, if I'm going to be a wise-ass, I might as well offer a potentially useful suggestion also. Here's an idea: Mark one tooth, as you've been doing. Then roll the gear firmly on a piece of paper, so that the teeth make distinct indentations. Label two indentations made by the marked gear, so that one full revolution is known to occur between the two labels. Then repeatedly fold the paper (accounting for possible odd numbers of indentations) until it's easy to count the indentations in a fold and multiply by the number of folds (adding one as appropriate). Might that save you some time and increase the accuracy, maybe?
