paper astrolabe

Learned about an educational web site today. And discovered they had a little project whereby you could build your own astrolabe! Funny. I've been thinking about wanting a device like this for a while, to more accurately gauge or measure elevation or altitude of objects in the sky.

I've already made some mods:
  • I printed another copy of the scale but reversed, flipped horizontally. I affixed this on the opposite side of the cardboard plate. Now it's double-sided, the scale.
  • I will use a loop of string through the hole at the apex as opposed to tying a single strand. This will then show the vertical line on either side of the plate.
I shall try it out this weekend, at Mom's...
