I just made another circuit solution, much simpler than my first.
Breadboarded it and everything works great, and doesn't seem at all
affected by voltage - a circuit I can actually use!
8 components. Any bids below 8 components? :-)
Eagle eyed observers may note that as well as inverting the truth table
(it now shows the HC240 inverted output instead of the enable pin
states), it differs in one respect from the one specified, but even
eagler-eyed observers will have read the blurb on what the "gate" is
for, and realised that the only thing the change actually changes is the
polarity in which you wire up the completely non-polarised motor :-)
