I used some perf board to wire up my circuit point to point - put the component lead through the holes and pull it to where it needs to connect then solder. ~50 components.
I thought I'd be cute and work from a pcb auto routing program. Somehow I managed to get "turned around" and forgot which side of the board I was working on - the net effect was to swap pins 1and 14 around - and 2-13, and 3-12, etc. etc.
I "rang it out" (used an ohm meter to check connections) and discovered the mistake. Also fortunate to use an IC socket. I pulled the picaxe out carefully bent every pin 180 degrees and put it in the socket upside down. Works like a champ.
