Subject: [alt-beam] Walker with reverser in one chip! (schematic)

Hi list
I just thought I'd post this schematic for a bicore driven walker that
has reverse. The cool thing is that it fits into one chip! (excluding
motor drivers) Just freeform the circuit and use your motor driver of
choice. If you have any questions let me know.
Value code
--------
Violate capacitors - .22 uF Bipolar
Orange capacitor - around 30uF
Red resistors - 1.6M Ohm
Blue resistor - 2.5M Ohm
Green resistors - 47K Ohm
BTW: I've been having TONS of problems with my ISP so I couldn't upload
the schematic to my web site. It's only 17K so it should only take a few
second to download.

True, but the hc14 is a convinent package. It has six inverters
2 inverters for one bicore (only one's needed)
2 inverters for the reverse
2 inverters for two Nu's to controll the reverse/
And I think it's possible for the Nu's to directly controll the reversing
process. So It's just a matter of preference.
