Hi, Stick.

If you were looking at Ian's circuit labelled "reverser", go down two
circuits further and take a look at the "Complete walker".

Without knowing precisely which circuit you are using, the general idea
is to hook a touch sensor up to a switch which connects the input of an
inverter to ground through a resistor. Typically you already have a
resistor going from that point to ground, so your touch switch connects
a second one parallel to it, thus reducing the delay time of the neuron.
Get's somewhat more complicated with a floating bicore.

No such thing :)

Close! Actually, it's more lack of space. I've even had to take down the
walls of my own RJP to make room for another person (wife) to help work on
BEAM/WCRG stuff. It's right in front of a sunny window (perfect for RJP,
lousy for computer), so perhaps if all goes well, I'll be able to steal it
back.


Sigh...

'Tis a concept we're working on. Hopefully this summer when Kenny the
wonder-web-boy is back in our employ...
