I saw on youtube a programmable AC/DC adapter/sequencer, about the size of a hand held transistor radio, that output 4.5V DC to 8 different outputs, for programmable time intervals. I SAW IT! Can't find anything like it. Does anyone know of such a thing? It would be perfect for our display of just a few Lemax audio/animated buildings, so they don't all come on at the same time and annoyingly blast sound over each other, causing me to turn them all off. Looking for a simple, turn-key solution, not something you need to be a soldering or electronics geek to understand and install. Plug it in and it works! I saw on working on youtube! I can't even find the video now let alone the device. I can't believe there is no market for such a device, but it sure seems that way.
