“When Jim’s thirty year old Pachinko machine started to freeze up and shorted out his computer’s graphics card he decided it was time to replace the old electronics with an Arduino. Originally the Pachinko machine ran off a 48 volt supply and control was achieved using about 20 relays, the random numbers were generated using some complex mechanical reels which we hope will find their way into a new project in the future.” via Hackaday
