I knew going in that I was confused by a specific part of the directions which stated,
"Solder up the rest of the circuit for flashing the LEDs: Add the power transistor to the perf board and after noting the E, C, and B legs, wire up the connections to the speaker, then solder the connections to the dropping resistor and the 2 LEDs."
Although I wasn't quite sure what to do at this point, I'd figured that a combination of experimenting, Googling, tweeting, and emailing might help me conquer the hurdle. For now, I have reluctantly reached a pausing point.
If you have made this project, or think you might be able to help me, I would be most grateful!
While I'm out of ideas, I am more determined now than ever to figure this sucker out.
