At the bench in my old lab, presenting the rpi2caster project. It's a Raspberry Pi based computer control device for a Monotype composition caster, a hot metal typesetting machine developed at the turn of the 19th and 20th century. I made three of these units, and two prototypes. Talking about how I built it, engineering challenges and some history.
