Subject: RE: i swear the circuit's correct!!!


I had my 74HC14 act odd when a single 74HC245 motordriver wasn't sufficient
to run the cirquit. Two 74HC245's did the trick and it worked like a charm.

I got both neurons in front firing at the same time and both in back right
afterwards.

Hope this helps,

Thomas
