@alexpikkert Thanks! I'll look into that, and I'll keep an eye out for the 9V threshold.
@JackANDJude I don't have enough experience yet, but I've been considering picking one of the HDKs up once I have a better grasp of electronics. (I have a Rad-Fi kit coming to see if it'll help me understand things better as far as electronics for music, specifically.) Danke!
@sc4r4b Cool ideas! They might not be what I was looking for w/r/t power starve stuff, but I'll have to give those a try at some point. Thanks!
@waxmoose Nice, I'll have to take a gander at that stuff, though I'll have to get some more electronics knowledge under my belt before taking the plunge. Though I guess trial and error are part of the learning process... :-o Thank you!
Thanks again, everyone--I have some research (and development?!) to do! Now to find the time. Well, make the time!
