Thank goodness it is Friday. Nothing too scary this week. Typical Glenn, teething, screaming, but sleeping well.

Work has been keeping me busy, as always, but not too busy.

Even though I an Electronics Engineer, I have a growing respect for purely mechanical things. In particular, mechanical watches. To me, it is fascinating how something designed 100 years ago works so well. No battery, no motors, just some springs and cogs and gears. Automatic watches are an even more amazing chunk of technology. Just the motion of your arm winds the watch. This is done using what is known as a rotor, which is just an uneven weight.

(This is a Seiko 7S26 automatic movement.)

Just look at how much stuff gets crammed in a watch case. This modern movement is based on designs from the late 50’s. It has about 40 moving parts. The more I read about mechanical watches, the more respect I have for long dead engineers and watchmakers.
