I'll start off by saying that I am all too aware of the differences between AC and DC.
Last night I was finishing up a hack. I am putting a USB 2.0/FW 400 bridge and a removable hard drive rack into a old NEC CD-ROM case. So I reached into my bin-o-wall warts and pulled out one that said 12v 1 amp. I said great that will work to test with. Pluged it in and 30 sec later POP. I unplug it and look at the power adapter. The oputput is 12v AC not DC. DOH!! I pull the case apart and it blew one of the CAPs in the voltage regulator.
I plan on replaceing the cap but I am conserned that I may have damaged the voltage regulator. Does anyone know if this is likely or am I just worrying about nothing?
