I hate to throw out AC adapters/wall warts. They're probably full of toxic substances, and I always have the nagging suspicion that I might be able to use them again in some fashion. I don't have much storage space in my little house, but I have one of the 4"x4"x8" stacking bins in my linen/storage closet set aside for old AC adapters. I suspect that my roommates think I'm a packrat, but I can't quite say I give a rat's ass. Apparently, my dad is the same way. I'm at my folks' house right now and discovered that my M-Audio FireWire Solo, which I had heretofore only used with my desktop PC, won't power up when plugged into the PCMCIA FireWire adapter I bought the other day for my laptop. The FireWire Solo requires a 12VDC power supply providing 1000mA. I've got one of those at home, but that's 1900 miles away. I went down to my folks' basement, hunted around a bit, and found more or less what I needed: a 12VDC power supply pushing 800mA. I doubt it's regulated, but it appears to have come from my dad's old C-PAP (automatic air pump he uses to control his snoring), so I can't imagine that it'd fry electronics too easily. So, instead of having to go to Rat Shack and hunt around for a 12V adapter that pushes more than 200mA, I have a usable FireWire Solo that will power a phantom-powered mic. Now to just record some damn music.
