@anthracite i've actually built a pendulum with the sort of ratchet mechanism they use in clocks with lego technic and i recommend it! it was a fun mental exercise and really satisfying to see in motion even if it doesn't run for long
I found a guy on Youtube who made one that he said kept running over an entire year, and only lost a few seconds! Plus a lot of wear to the parts, plastic's really not durable enough for all that constant motion.
@anthracite I recc Wristwatch Revival on YT if you want some good videos on teardown and buildup, and talk about the way components interact preparatory to doing your own build/etc
I'm a grumpy queer dragon lady and this is my quiet cave for me and some friends.
