Someone either goobed the math on the needed resister or fed the wrong resisters into it... i always thought the surface mount stuff was only done by machine but google shows otherwise.

Still prefer a different way: the digital pot chips are pretty cheap and have serial line interfaces which is easy... but no takers.
