>From Esa's closeup, the single component on the board is labeled IC2. However, it is only a 2-port device (only two wires are connected). There are other components labeled including IC1. The board is labeled "Roth Electronics Company RE901". Interesting that it is a surface mount board, an unnecessary complication for this demonstration. Terry
