Isn't it cool when you invent something only to find out that it's already been invented?

I've got this old-timey pendulum clock that I got from a Freecycler and it loses time; like 10 - 20 minutes every 2 - 3 days.

Well, I never gave it much thought, I mean, it's an old-timey, pendulum, type clock; you expect something like that to lose time.

Well, as I was thinking about how hard it would prove to be to change the gears to account for such small increments of time, I thought if only you could make the pendulum move faster, such as if it was shorter...

A few more minor links and I realized you could make everyone's home-clock easily adjustable with an adjustment for the pendulum length. I pulled my clock off the wall and sure enough, the pendulum had a little weight on the end that screws upwards and downwards to change the rate of swing, therefore time, through the speed of the gears.

Sometimes it frustrates me, because it's already been done, and other times it justifies me, such as this time. It works.*

(*An assumption since the adjustment is really there. I only found it, (and adjusted it,) minutes ago.)
