Way-T Electronic Hourglass
The concept of the hourglass has been given a modern twist whereby FiveCo has replaced the sand with LEDs that change from green to red as time trickles by.
As requested by Temporel SA, FiveCo constructed the whole electronic hourglass, from prototype to final commercial version.
The hourglass is made of very few components and therefore easy to put together. It is simple and efficient.
