JustJ0n made a replica of Green Lantern power battery from Lego. But what is a lantern without a ring to power it up?
Inside the lantern is an Arduino responsible for activating the lights when the RFID ring is near it.
A nice mixture of fantasy comics and modern technology coming together.

Alain V. made a simple project with an RFID reader attached to an arduino microcontroller which sends the commands to a pc and enables him by selecting different cards or tokens to start play a playlist or stop it. Nice, simple and does the job with a hi-tech touch. You can find all the info you need here.
