The Ping Pong Printer

Vern Graner and Rick Abbott of The Robot Group built an inkjet printer for ping pong balls:

Why print on boring old paper, when you can get your message across on some nice bouncy ping pong balls? The appropriately named PingPongPrinter can print dot-matrix messages directly onto the spherical surface of ping pong balls.

Builders Vern Graner and Rick Abbott of The Robot Group used a Parallax inkjet print head kit and the EFX-TEK Prop-2 controller board to bring their wondrous creation to life. As each ball leaves the hopper, it’s loaded onto a rotating platform, and sprayed with tiny ink droplets.

The best part: the balls it prints are used as ammunition for the group’s other dastardly invention, the pneumatic, ping pong ball firing PONGINATOR!
