Hi Jay,

If you mean that me, personally, am in need of a layer of fuzzy logic, you're a bit late - it's been in place since my first major electric shock (at 6) - just ask my wife!

I've just finished another evening working session with friend Ralph, who wants a device to track a light source. The next prototype will use an 8751, 3 photo sensors, A/D conversion & 2 stepper motors - an ear for light waves?

Time for some shut-eye (23:00 CET).

Bye,
Richard
