Pongmechanik

This electro-mechanic Pong Game is just too cool! The guy spent 900 hours to build a mechanized version of the original Pong game. He used 52 old telephone relays (vintage 1958) to create the controller. The collision detection is actually done through electric contacts. I think this explains a lot about why German engineering and craftsmanship rules...

I didn't initially notice that the site was in German (I guess I'm not as rusty as I thought). The video has English sub-titles, though.

The construction reminds me of the inverted pendulum I saw at the EPFL while visiting Christophe Salzman and the smaller one built by Doug Norman at NI. But it's the relay controller that really kicks ass.
