Erik Gregg (Hank) wanted a name badge using an 16×2 alphanumeric display for use at conferences, nerdfests, etc. He constructed this simple ATtiny2313 based badge which interfaces with the LCD with a minimum of components. This project is based upon this Instructable. He took the Instructable to the next level by moving from breadboard to PCB.
