Thanks for the positive remarks. It was one of those builds where the info is scattered all over the place... no "Technology of" article to be had... I think this list covers most of what is known about the circuit.
For anyone who uses this list and builds a Dr. Boogey, if you learn something that isn't on the list or do something different that works, then please post a link to your build report here. Build reports are the one of the most important parts of the evolution of the DIY community.
