Quoted from HankScorpio:Lyonsden and I were making several products under Prof. Pinball, but I was the one making the Pinball Shields. He makes the super incredible Pinduino, which I absolutely love.

These shields are the brain-child of the great HankScorpio! They are a must. (and thanks for the Pinduino shoutout).
