Euler's Disk - Charity Shop Find - 12v Solar Shed

A charity shop find which doesn't include any electronics at all. This is a Euler's Disk and is a toy or educational demonstration model to show the dynamic system of a spinning disk.

Visually it's quite interesting, but I love the noise it makes.

This item was bought from a charity shop, but they can be found on Ebay:

Very cool and the best part you do the work of spinning it and storing it in the closet.

You need a more solid/level surface for it to work longer/faster. That clattering is from skips and jumps caused by opposing vibrations on your table, which hinders the effect and slows it more quickly.

It's pronounced "Oyler's Disk"
