#107: Shop window turntables

Today’s invention is a cheap alternative display system for shop windows.

It involves using a number of those low-cost, square electronic clock mechanisms, which are battery-powered. Remove the hands in each case and replace the second hand with a small, round platform.

Placing a lightweight object for sale on this mini turntable would allow it to slowly rotate in the shop window, adding a certain extra visual interest at very little additional cost. This effect would be enhanced by playing the usual spotlights on the object(s) in question and by having a large array of merchandise items. Battery replacement need only happen once or twice a year.

For those with an interest in ‘novelties’, it would be possible to make an internal sundial using one such clock mechanism with a stationary light source and a pointer attached to the turntable.
