Description: An ‘anemometer’ is a device that measures wind speed. You can buy them, but they are usually quite small.
So I decided to build one myself. The BLANDA BLANK servings bowls are excellent for this purpose. Twelve centimeters in diameter, you can’t ignore them when they are spinning around in the wind.
The rest is PVC tubing, with red spray paint. The bearing that allows for smooth rotation is the motor from a hard drive. The shiny disks from the drive add bling to the device. The finishing touch, the big green glass marble, I bought in a toy shop.
