           I checked again and the signal is rather marginal. It might be
           that they are using different makes of sensor which have
           different characteristics.

           I spent a long time trying to find out what was going on, and
           eventally realized that there is a design fault with the board
           I have. On my board the series resistor in the LED circuit (the
           only component on the board apart from the sensors) is 820
           ohms. This is simply incorrect. The correct value is 100 ohms.
           The too-high value causes the LEDs not to emit enough light
           and the sensing doesn't work properly. If you also have an
           820 ohm resistor (marked 821) then soldering an 100 ohm
           one across it will cure the problem.

I'm confused.  Is he saying that the Opti-PAC has an incorrect resistor in the LED circuit?

No.  The optical board on the tornado spinner does.
