One of the challenges of building a large chaos machine is that each of the elevators (either the old screw-style or the new chain-style) requires a separate power brick. If you’ve got 4 or 5 elevators, then you’re going to need a lot of power strips and/or squids. Until now.
Today my wife and I went shopping at the local Micro Center, and while I was checking out, she went next door to Michaels. When I went in after her, I noticed an interesting widget in the seasonal decoration area: a 1A, 4.5V power brick that had three (3) separate output jacks. Just the thing to drive three elevators at once. The manufacturer is Lemax, and they have them in black (Halloween) and white (Christmas). (Wait until AFTER the holiday if you want the bargain prices.)
