74*14-based photopopper circuits - 0 views

Droidmakr (Cliff Boerema) came up with an interesting idea for a light-tracking head with a form of peripheral vision. As often happens, the circuit turned into something different -- a photopopper:
-
All done with a single 74HC14 (the '240 being a motor driver).
-
I tried the same setup with the 74*240 (with an extra inverter per motor) and 7404, but the 74HC14 seems to work best.
