#1719: SpinScreen

Making a colourful circular display using lights and the persistence of vision is a technology that you can buy off the shelf to decorate your car’s wheels.

Today’s invention is an upgrade to that approach.

If you are sick of the small size of your smartphone screen, you can clamp the device onto a handle with an internal motor and spin it, as shown.

Running an application simultaneously allows the persistence of vision to show eg messages or even low-res movies on a virtual screen area roughly 3Pi/4 times as big.
