Mixed success this week - I was able to get two projects working; however several others did not work.  Not sure if the issue is difference in components or not.  At this point I'll probably work on circuits *based* on the original projects but tweaked to work with my new hardware. 

Project examples (need to create YouTube videos... :-o )

(Note that original speaker on PCB is pretty small and not very loud!!
