It is no secret that you can do a lot of fun things with a Spark Core. Those of you who are a fan of the Avengers are going to find this project interesting. The below video demonstrates how a Spark Core and Internet Button can be used to create an Iron Man Repulsor and Arc Reactor.
The Repulsor uses the Button’s accelerometer to determine what position your hand is in. When you hold your hand at a 90 degree angle, an event is published to the cloud. The servo and the Reactor are subscribed to the cloud for that event. Overall, this is a fun project to try especially for those of you learning how to create new things with Spark products.
