Instead of rock-hard bubble gum that loses its flavor after 2 minutes, this gumball machine delivers apps and games directly to your smartphone.
The communications protocol used by this app-delivering gumball machine isn’t bluetooth or WiFi but near field communication. This protocol allows for a point-to-point network between the app dispenser and a phone to deliver games, music, videos, and ebooks to any compatible portable device.
The hardware for the gumball machine is a Galaxy Tab, an Adafruit NFC shield, two Arduinos, and a few switches and other components stuffed into an old gumball machine. To get purchase an app, just put a quarter or two in the machine, turn the crank, and put your phone up against the dispenser. Through the magic of near field communications, you phone or tablet receives whatever media you purchased.
Near field communication has been a standard for a while, but hasn’t been available in most phones. With oracles of Apple speculating the upcoming iPhone will have NFC capability other phone manufacturers are sure to pick up the tech. Very cool project, and we can’t wait to see some truly home-brew versions of this build.
Vidia after the break.
