[...]This PayPal vending machine on exhibit at the PayPal X Innovate 2010 developers conference was created by Ray Tanaka and his crew at PayPal Labs.

They hacked together the multi-part system using a mechanical candy dispenser, a couple of Arduino Duemilanove, a WiShield, relay, proximity sensor, and LED display.

The end result allows you to scan a QR code, make a payment, and acquire munchies using a smartphone. As you make your payment, the machine will tweet your purchase and notify a confirmation display.

Martin Bircher “Type Case” is a low-resolution display made out of an old case used to hold printer’s lead type. The 125 rectangular “pixels” reflect light from Arduino-controlled LEDs. In the videos on his Vimeo page, different types of visual information are displayed on the Type Case, including scrolling headlines and a Betty Boop cartoon.

Martin says: “Viewed close up, it is nearly impossible to recognize more than a flicker – however after moving some distance away, it becomes distinguishable, that the lights and shadows give a representation of the latest headlines.”
