Note that the schematic in the article shows the op-amp with positive 
feedback.  The connections to the + and - op-amp inputs should be 
swapped to make it a noninverting amplifier with voltage gain of 
22.  (That is, the 100k resistor should go from op-amp Pin 6 to Pin 
2, not to Pin 3.)

Best regards,
