LED Coaster - Wireless/Batteryless

A new take on the LED coaster with wireless power charging and supercapacitor energy storage.

Similar projects worth following
LED drink coasters are nothing new, but what about one that charges wirelessly and doesn't require traditional chemical batteries? When not in use simply place the coaster in it's charging base to recharge.

Using slim supercapacitors will allow for a thin and light design.

The charging base and coaster will communicate to ensure to ensure that when charging, the LEDS will be off, and once fully charged the charger will turn off so as not to waste energy.
